    2016-01-01

    We describe a novel papillomavirus - Rusa alfredi papillomavirus 1 (RalPV1) - which causes endemic fibropapillomatosis in the European conservation breeding population of the highly endangered Visayan spotted deer (Rusa alfredi). Degenerated papillomavirus-specific primers were used to amplify and sequence parts of the viral DNA. Subsequently, the complete genomic DNA was cloned and the sequence was determined. The RalPV1 genome has a length of 8029 bp, encodes the early proteins E6, E7, E1, E2 and E5, the two late proteins L1 and L2 and contains an upstream regulatory region. Highest sequence identities were observed with two deltapapillomaviruses, the Capreolus capreolus PV1 and Cervus elaphus PV1. Pairwise comparisons and phylogenetic analysis based on the ORF L1 suggested that RalPV1 is a putative new type of the papillomavirus species Deltapapillomavirus 5. PMID:26555294

    2015-01-01

    After initial observations of suspicious cases in 2009, the occurrence of Fascioloides (F.) magna in deer of a deer farm located in northeastern Bavaria, Germany, at the border to the Czech Republic was confirmed in autumn 2011. In March 2012, the deer were treated for fascioloidosis with triclabendazole. To monitor the epizootiology of fascioloidosis in the farm, 80-100 faecal samples were examined for Fascioloides eggs at monthly intervals from June 2012 to June 2013 inclusive. In addition, livers of 27 red deer and one sika deer collected during winter 2012/2013 were examined for gross lesions suspicious for F. magna infection and 21 of the 28 livers were dissected for F. magna recovery. Fascioloides eggs were recorded in 63 (4.9%) of 1280 faecal samples (range 0.4 to 355 eggs per gram). Both, number of Fascioloides-egg positive samples and egg counts were low during the first eight months of the study but increased notably since February 2013. While Fascioloides egg-positive faecal samples were obtained from red deer (46/948,4.9%) and fallow deer (17/166, 10.2%), no Fascioloides eggs were demonstrated in the 166 samples obtained from sika deer. Livers of five red deer and the sika deer showed gross lesions characteristic for fascioloidosis, and F. magna were recovered from three of the five affected red deer livers (range, five to seven flukes). Results of this study confirm that F. magna is endemic in the deer farm, and measures should be implemented to minimize the transmission of the parasite. PMID:26054221

  7. Yersiniosis in farmed deer.

    Jerrett, I V; Slee, K J; Robertson, B I

    1990-06-01

    Samples from 77 chital (Axis axis), 42 fallow (Dama dama), 26 red (Cervus elaphus), 7 rusa (Cervus timorensis) and 1 sambar deer (Cervus unicolor) were examined. Yersinia pseudotuberculosis infection was diagnosed as the cause of death in 6 (23%) of the red and 23 (30%) of the chital deer. Yersiniosis was the most common infectious cause of death diagnosed. Affected deer were usually found moribund or dead, often with faecal staining of the perineum. Gross pathology in chital included a fibrinous enterocolitis, enlarged congested mesenteric lymph nodes and multiple pale foci through the liver. Gross changes in red deer were limited to intense congestion of the intestinal mucosa and enlargement and congestion of mesenteric lymph nodes. Microscopic intestinal changes in both species consisted of microabscessation or diffuse suppurative inflammation of the intestinal mucosa with numerous bacterial colonies in the lamina propria. Multifocal suppurative mesenteric lymphadenitis was a common finding. Multifocal suppurative or non-suppurative hepatitis was frequently present in the liver of chital but was uncommon in the red deer. Yersiniosis occurred during the cooler months from June to November, with younger age classes most commonly affected. Y. pseudotuberculosis serotypes I, II and III were isolated in the ratio 17:3:0 in the chital deer and 1:1:2 in red deer. The clinical, epidemiological and bacteriological features are similar to those documented previously by New Zealand workers. The increased susceptibility to disease of red deer and chital compared to fallow deer and perhaps other species has not previously been documented. PMID:2222364

  10. SRP deer hunt data base

    The Savannah River Plant (SRP) site is an ideal habitat for white-tailed deer. The large deer population of more than 6000 animals has resulted in collisions between deer and automobiles. To control this population and thus reduce accidents, deer hunts were begun in 1965. These hunts are organized and supervised by U.S. Forestry Service Personnel. The deer have access to all of the plant site except the fenced operating areas. Access to radioactive liquid effluents and contamination vegetation can result in radioactive body burdens in deer. Prior to 1970, samples of about 20% of the deer shot during the deer hunts were radioassayed. Based on these results and plant effluent information, 137Cs was the radionuclide of interest. A portable instrument was developed to measure 137Cs in deer and, beginning in 1970, all deer have been monitored for their 137Cs concentration before being released to the hunters. All slain deer were released to the hunters immediately after monitoring; no deer were above acceptable safe limits for food

  11. Infectious Disease and Grouping Patterns in Mule Deer.

    María Fernanda Mejía Salazar

    Full Text Available Infectious disease dynamics are determined, to a great extent, by the social structure of the host. We evaluated sociality, or the tendency to form groups, in Rocky Mountain mule deer (Odocoileus hemionus hemionus from a chronic wasting disease (CWD endemic area in Saskatchewan, Canada, to better understand factors that may affect disease transmission. Using group size data collected on 365 radio-collared mule deer (2008-2013, we built a generalized linear mixed model (GLMM to evaluate whether factors such as CWD status, season, habitat and time of day, predicted group occurrence. Then, we built another GLMM to determine factors associated with group size. Finally, we used 3 measures of group size (typical, mean and median group sizes to quantify levels of sociality. We found that mule deer showing clinical signs of CWD were less likely to be reported in groups than clinically healthy deer after accounting for time of day, habitat, and month of observation. Mule deer groups were much more likely to occur in February and March than in July. Mixed-sex groups in early gestation were larger than any other group type in any season. Groups were largest and most likely to occur at dawn and dusk, and in open habitats, such as cropland. We discuss the implication of these results with respect to sociobiology and CWD transmission dynamics.

  13. Chronic Wasting Disease Drives Population Decline of White-Tailed Deer.

    Edmunds, David R; Kauffman, Matthew J; Schumaker, Brant A; Lindzey, Frederick G; Cook, Walter E; Kreeger, Terry J; Grogan, Ronald G; Cornish, Todd E

    Chronic wasting disease (CWD) is an invariably fatal transmissible spongiform encephalopathy of white-tailed deer, mule deer, elk, and moose. Despite a 100% fatality rate, areas of high prevalence, and increasingly expanding geographic endemic areas, little is known about the population-level effects of CWD in deer. To investigate these effects, we tested the null hypothesis that high prevalence CWD did not negatively impact white-tailed deer population sustainability. The specific objectives of the study were to monitor CWD-positive and CWD-negative white-tailed deer in a high-prevalence CWD area longitudinally via radio-telemetry and global positioning system (GPS) collars. For the two populations, we determined the following: a) demographic and disease indices, b) annual survival, and c) finite rate of population growth (λ). The CWD prevalence was higher in females (42%) than males (28.8%) and hunter harvest and clinical CWD were the most frequent causes of mortality, with CWD-positive deer over-represented in harvest and total mortalities. Survival was significantly lower for CWD-positive deer and separately by sex; CWD-positive deer were 4.5 times more likely to die annually than CWD-negative deer while bucks were 1.7 times more likely to die than does. Population λ was 0.896 (0.859-0.980), which indicated a 10.4% annual decline. We show that a chronic disease that becomes endemic in wildlife populations has the potential to be population-limiting and the strong population-level effects of CWD suggest affected populations are not sustainable at high disease prevalence under current harvest levels.

    1991-01-01

    Seventy-six wild sika deer (Cervus nippon yesoensis) from areas endemic for Borrelia burgdorferi during 1988 to 1989 had the IgG antibody to the bacteria in enzyme-linked immunosorbent assay. The percentage of seropositive deer was 25.0% to strain HO14 and 22.4% to strain HP3, respectively. Specific IgG antibody titers were high in summer but low in winter. In summer, seropositive deer were 75.0%. Similar results were obtained in serum specimens obtained monthly from 4 farmed deer. It was suggested that the sika deer could be one of the wild reservoirs for B. burgdorferi in Hokkaido, Japan. The transmission risk of B. burgdorferi is considered to be greatest during late spring to early summer. PMID:1808467

  16. Genetic diversity among Chinese sika deer (Cervus nippon) populations and relationships between Chinese and Japanese sika deer

    2006-01-01

    Sika deer (Cervus nippon) is a cervid endemic to mainland and insular Asia and endangered. We analyzed variation in the mitochondrial DNA (mtDNA) control region for four subspecies to understand the genetic diversity, population structure and evolutionary history in China. 335 bp were sequenced and eight haplotypes were identified based on 25 variable sites among the populations. Sika deer in China showed lower genetic diversity, suggesting a small effective population size due to habitat fragmentation, a low number of founder individuals, or the narrow breeding program. AMOVA analysis indicated that there was significant genetic subdivision among the four populations, but no correlation between the genetic and geographic distance. Phylogenetic analyses also revealed that Chinese sika deer may be divided into three genetic clades, but the genetic structure among Chinese populations was inconsistent with subspecies designations and present geographic distribution. Including the sequence data of Japanese sika deer, the results indicated that Chinese populations were more closely related to Southern Japanese populations than to the Northern Japanese one, and the Taiwan population was closer to populations of Northeastern China and Sichuan than to those of Southern China.

  17. Habitat, wildlife, and one health: Arcanobacterium pyogenes in Maryland and Upper Eastern Shore white-tailed deer populations

    Melissa M. Turner

    2013-08-01

    antler and nasal swabs from deer were positive for A. pyogenes, respectively. On the Upper Eastern Shore, prevalence of A. pyogenes cultured from deer did not differ between management areas, and was abundant among both sexes and across all age classes. No A. pyogenes was cultured from a small sample of neonates. Conclusion: Our study indicates A. pyogenes may be carried widely among white-tailed deer regardless of sex or age class, but we found no evidence the pathogen is acquired in utero. The distribution of A. pyogenes across regions and concentration in a region with low livestock levels suggests the potential for localized endemicity of the organism and the possibility that deer may serve as a maintenance reservoir for an emerging one health concern.

  19. Epidemiology, diagnostics, and management of tuberculosis in domestic cattle and deer in New Zealand in the face of a wildlife reservoir

    Buddle, BM; de Lisle, GW; Griffin, JFT; Hutchings, SA

    2015-01-01

    Abstract The control of tuberculosis (TB) in cattle and farmed deer in New Zealand has been greatly influenced by the existence of a wildlife reservoir of Mycobacterium bovis infection, principally the Australian brushtail possum (Trichosurus vulpecula). The reduction in possum numbers in areas with endemic M. bovis infection through vigorous vector control operations has been a major contributor to the marked reduction in the number of infected cattle and farmed deer herds in the past two de...

  20. Applications of mathematical modeling in managing the spread of chronic wasting disease (CWD) in wild deer under alternative harvesting scenarios.

    Al-Arydah, M; Croteau, M C; Oraby, T; Smith, R J; Krewski, D

    2016-01-01

    The application of a recently developed mathematical model for predicting the spread of chronic wasting disease (CWD) in wild deer was assessed under different scenarios where harvesting is employed in disease management. A process-based mathematical model for CWD transmission in wild deer populations was recently developed and parameterized by Al-arydah et al. (2011) to provide a scientific basis for understanding the factors that affect spread of CWD and evaluate concomitant disease-control strategies. The impact of gender on CWD transmission was shown to have a significant influence on the spread of the disease in the wild. Our model demonstrates a range of harvesting rates in which CWD is controlled and deer populations survive. However, if harvesting rates are too low, the disease remains endemic for decades. Conversely, the Canadian deer population is eradicated if harvesting rates are excessive. Future investigation includes building the model to assess the spread of CWD under different disease-management scenarios. PMID:27556563

    David eGonzález-Barrio

    2015-12-01

    Full Text Available Several aspects of the dynamics of Coxiella burnetii that are relevant for the implementation of control strategies in ruminant herds with endemic Q-fever are unknown. We designed a longitudinal study to monitor the dynamics of exposure to C. burnetii in a red deer herd with endemic infection in order to allow the design of Q fever specific control approaches. Other relevant aspects of the dynamics of C. burnetii - the effect of herd immune status, age, season and early infection on exposure, the average half-life of antibodies, the presence and duration of maternal humoral immunity and the age of first exposure - were analysed. The dynamics of C. burnetii in deer herds seems to be modulated by host herd and host individual factors and by particular host life history traits. Red deer females become exposed to C. burnetii at the beginning of their second year since maternal antibodies protect them after birth and during the main pathogen shedding season - at the end of spring-early summer. Infection pressure varies between years, probably associated to herd immunity effects, determining inter-annual variation in the risk of exposure. These results suggest that any strategy applied to control C. burnetii in deer herds should be designed to induce immunity in their first year of life immediately after losing maternal antibodies. The short average life of C. burnetii antibodies suggests that any protection based upon humoral immunity would require re-vaccination every 6 months.

    Hybridisation between introduced and endemic species causes conservation concerns, but also provides us with an opportunity to study the dynamics of gene flow between two species as they first meet. Japanese sika deer (Cervus nippon) were introduced to the British Isles at a number of locations at the beginning of the 20th century. In the intervening time, sika have spread and their range now extends across approximately 40% of Scotland, where they overlap with that of native red ...

  4. Aerial survey estimates of fallow deer abundance

    Gogan, Peter J.; Gates, Natalie B.; Lubow, Bruce C.; Pettit, Suzanne

    2012-01-01

    Reliable estimates of the distribution and abundance of an ungulate species is essential prior to establishing and implementing a management program. We used ground surveys to determine distribution and ground and aerial surveys and individually marked deer to estimate the abundance of fallow deer (Dama dama) in north-coastal California. Fallow deer had limited distribution and heterogeneous densities. Estimated post-rut densities across 4 annual surveys ranged from a low of 1.4 (SE=0.2) deer/km2 to a high of 3.3 (se=0.5) deer/km2 in a low density stratum and from 49.0 (SE=8.3) deer/km2 to 111.6 deer/km2 in a high density stratum. Sightability was positively influenced by the presence of white color-phase deer in a group and group size, and varied between airial and ground-based observers and by density strata. Our findings underscore the utility of double-observer surveys and aerial surveys with individually marked deer, both incorporating covariates to model sightability, to estimate deer abundance.

Adequate data on the epidemiology of bejel and pinta is lacking. Each disease is restricted to a specific ecologic...

  6. Lions and prions and deer demise.

    Michael W Miller

    Full Text Available BACKGROUND: Contagious prion diseases--scrapie of sheep and chronic wasting disease of several species in the deer family--give rise to epidemics that seem capable of compromising host population viability. Despite this prospect, the ecological consequences of prion disease epidemics in natural populations have received little consideration. METHODOLOGY/PRINCIPAL FINDINGS: Using a cohort study design, we found that prion infection dramatically lowered survival of free-ranging adult (>2-year-old mule deer (Odocoileus hemionus: estimated average life expectancy was 5.2 additional years for uninfected deer but only 1.6 additional years for infected deer. Prion infection also increased nearly fourfold the rate of mountain lions (Puma concolor preying on deer, suggesting that epidemics may alter predator-prey dynamics by facilitating hunting success. Despite selective predation, about one fourth of the adult deer we sampled were infected. High prevalence and low survival of infected deer provided a plausible explanation for the marked decline in this deer population since the 1980s. CONCLUSION: Remarkably high infection rates sustained in the face of intense predation show that even seemingly complete ecosystems may offer little resistance to the spread and persistence of contagious prion diseases. Moreover, the depression of infected populations may lead to local imbalances in food webs and nutrient cycling in ecosystems in which deer are important herbivores.

  7. Enterocytozoon bieneusi in sika deer (Cervus nippon) and red deer (Cervus elaphus): deer specificity and zoonotic potential of ITS genotypes.

    Zhao, Wei; Zhang, Weizhe; Wang, Rongjun; Liu, Weishi; Liu, Aiqin; Yang, Dong; Yang, Fengkun; Karim, Md Robiul; Zhang, Longxian

    2014-11-01

    As the most common cause of the human microsporidiosis, Enterocytozoon bieneusi has been found in a wide variety of animal hosts. Deers are the ruminant mammals living in a variety of biomes, and the distribution of deer species differ by geography. To understand the prevalence of natural infection of E. bieneusi in deer and to assess their epidemiological role in the transmission of microsporidiosis caused by E. bieneusi, 91 fecal specimens were collected from 86 sika deers and five red deers in the northeast of China. By PCR and sequencing of the internal transcribed spacer (ITS) region of the ribosomal RNA (rRNA) gene of E. bieneusi, an average infection rate of 31.9% (29/91) was observed in deer, with 32.6% (28/86) for sika deer, and 20% (1/5) for red deer. Six ITS genotypes were identified: one known genotype BEB6 (n = 20) and five novel genotypes HLJD-I to HLJD-IV (one each) and HLJD-V (n = 5). A phylogenetic analysis based on a neighbor-joining tree of the ITS gene sequences of E. bieneusi indicated that genotypes HLJD-II and HLJD-III fell into group 1 of zoonotic potential, while the other genotypes (BEB6, HLJD-I, HLJD-IV, HLJD-V) were clustered into so-called bovine-specific group 2. This is the first report of E. bieneusi in deer in China. The observation of genotype BEB6 in humans previously and in deer here and also the findings of the two novel genotypes (HLJD-II to HLJ-III) belonging to potential zoonotic group 1 suggested the possibility of deer in the transmission of E. bieneusi to humans.

  8. Welfare issues of modern deer farming

    Silvana Mattiello

    2010-01-01

    Full Text Available This paper will start with briefly outlining the recent domestication history of red deer (Cervus elaphus and fallow deer (Dama dama, followed by a description of the present status of modern deer farming. It will then review the main welfare issues of deer farming. The following aspects will be considered: accommodation and housing, management and handling, nutrition (feed and water provision, transport and slaughter, plus a short mention of velvet harvest. As a summary, the following practices can be recommended to ensure animal welfare in modern deer farming: the adoption of suitable housing systems and of adequate management techniques (e.g. specific handling pens and drop-floor cradles or crushes and the respect of specific needs (e.g. provision of protection and shelter from predators as well as from climatic extremes, such as cold winds or direct solar radiation. Handling and yarding operations will be easier when they occur in dim light. Special attention must be paid to the manipulation of the newborns. At the slaughterhouse, facilities must be designed specifically for deer. The presence of well trained stockpersons, with a sound knowledge of deer physiology and behaviour, is also a key-factor for improving welfare levels in deer farms. To achieve these aims, training of the managers and stockpersons and the adoption of specific codes of conducts are highly recommendable.

  9. Identity of rumen fluke in deer.

    O'Toole, Ailis; Browne, John A; Hogan, Sean; Bassière, Thomas; DeWaal, Theo; Mulcahy, Grace; Zintl, Annetta

    2014-11-01

    As evidence is growing that in many temperate areas paramphistome infections are becoming more common and widespread, this study was undertaken to determine the role of deer as reservoirs for rumen fluke infections in livestock. A total of 144 deer faecal samples (88 from fallow deer, 32 from red deer and 24 samples from sika, sika/red deer hybrids) were screened for the presence of fluke eggs. Based on the ITS-2 rDNA locus plus flanking 5.8S and 28S sequences (ITS-2+), fluke eggs were identified to species level. Our results indicate that, of the 3 deer species, fallow deer had the highest fluke infection rates. Two rumen fluke species, Calicophoron daubneyi and Paramphistomum leydeni, with morphologically distinct eggs, were identified. Concurrent infections of the two paramphistome species and liver fluke, Fasciola hepatica, were common. Considering the comparatively low egg burdens observed in this study, it is unlikely that deer represent a significant source of infection for Irish livestock. PMID:25127736

    2009-01-01

    To determine whether Ehrlichia chaffeensis exists in Japan, we used PCR to examine blood from sika deer in Nara, Japan. Of 117 deer, 36 (31%) were infected with E. chaffeensis. The E. chaffeensis 16S rRNA base and GroEL amino acid sequences from Japan were most closely related to those of E. chaffeensis Arkansas.

  11. Antimicrobial Susceptibility Testing of Mycobacterium bovis Isolates from Michigan White-Tailed Deer during the 2009 Hunting Season

    Scott D. Fitzgerald

    2011-01-01

    Full Text Available Michigan has had an ongoing outbreak of endemic Mycobacterium bovis which has been recognized within and sustained by its free-ranging white-tailed deer population since 1994. Worldwide, organisms within the Mycobacterium tuberculosis complex have exhibited the ability to develop resistance to antimicrobial agents, resulting in both the multidrug-resistant (MDR and extensively drug-resistant (XDR strains of human tuberculosis. Michigan's Bovine Tuberculosis Working Group has conducted active antimicrobial susceptibility testing on wildlife isolates of the endemic M. bovis organism at five-year intervals to detect any emerging drug resistance patterns. The results of 33 white-tailed deer origin isolates collected from the 2009 hunting season are reported here. There continues to be no evidence of any drug resistance except for pyrazinamide resistance. These results are likely due to the lack of antibacterial treatment applied to either wildlife or domestic animals which would provide selection pressure for the development of drug resistance.

  12. Reproductive Behaviour Of Timor Deer (Rusa Timorensis

    Daud Sansudewa

    2011-09-01

    Full Text Available Timor deer (Rusa timorensis is a newly domesticated animal in Indonesia and other countries in the world. It is a potential source of meat and livelihood. Low birth rate is a problem of deer farming in Indonesia. It happens because of low concern for key aspects of behaviors including reproductive behavior. The aim of this review is to give information about reproductive behavior of Timor deer in natural habitat and captivity breeding. Libido and estrous behaviors of Timor deer in captivity breeding were similar with natural habitat. However, male Timor deer in captivity breeding took longer time to approach the females before mating, compared with those in their natural habitat. Aggressive behavior commonly leads mating. Parturition and maternal behavior of hinds are affected by limitation of space, therefore dividing the area of cage which depends on age and physiological status is needed to improve reproductive management.

  13. Immunohistochemical and biochemical characteristics of BSE and CWD in experimentally infected European red deer (Cervus elaphus elaphus

    Dagleish Mark P

    2009-07-01

    Full Text Available Abstract Background The cause of the bovine spongiform encephalopathy (BSE epidemic in the United Kingdom (UK was the inclusion of contaminated meat and bone meal in the protein rations fed to cattle. Those rations were not restricted to cattle but were also fed to other livestock including farmed and free living deer. Although there are no reported cases to date of natural BSE in European deer, BSE has been shown to be naturally or experimentally transmissible to a wide range of different ungulate species. Moreover, several species of North America's cervids are highly susceptible to chronic wasting disease (CWD, a transmissible spongiform encephalopathy (TSE that has become endemic. Should BSE infection have been introduced into the UK deer population, the CWD precedent could suggest that there is a danger for spread and maintenance of the disease in both free living and captive UK deer populations. This study compares the immunohistochemical and biochemical characteristics of BSE and CWD in experimentally-infected European red deer (Cervus elpahus elaphus. Results After intracerebral or alimentary challenge, BSE in red deer more closely resembled natural infection in cattle rather than experimental BSE in small ruminants, due to the lack of accumulation of abnormal PrP in lymphoid tissues. In this respect it was different from CWD, and although the neuropathological features of both diseases were similar, BSE could be clearly differentiated from CWD by immunohistochemical and Western blotting methods currently in routine use. Conclusion Red deer are susceptible to both BSE and CWD infection, but the resulting disease phenotypes are distinct and clearly distinguishable.

    A previous study showed that Sitka black-tailed deer (Odocoileus hemionus sitkensis) consumption was negatively correlated with monoterpene content in western redcedar (Thuja plicata). To test whether these monoterpenes were deterrent to Sitka black-tailed deer, we performed feeding choice experiments with four hydrocarbon (sabinene, myrcene, alpha-pinene, and d + l-limonene) and one oxygenated (alpha,beta-thujone) monoterpene solution at their highest natural concentration in western redcedar foliage. To test whether deer response was species specific, we ran similar experiments on European roe deer (Capreolus capreolus) and rusa deer (Cervus timorensis russa). In all experiments, monoterpenes were repellent. Solutions with alpha,beta-thujone, the major monoterpene in redcedar leaves, were the most repellent of the solutions tested. We then analyzed how black-tailed and roe deer responded to (1) an increase in concentration of the monoterpenes with the weakest repellent effects (hydrocarbon monoterpenes) and (2) a decrease in concentration of the monoterpene with strongest effect (alpha,beta-thujone). Repellency tended to increase with concentration for hydrocarbon monoterpenes, but remained strong for alpha,beta-thujone. As wild deer regularly feed on plants containing monoterpenes, this raises the question as to how the animals deal with these molecules. PMID:12564790

  16. The endemic treponematoses.

    Giacani, Lorenzo; Lukehart, Sheila A

    2014-01-01

    The agents of human treponematoses include four closely related members of the genus Treponema: three subspecies of Treponema pallidum plus Treponema carateum. T. pallidum subsp. pallidum causes venereal syphilis, while T. pallidum subsp. pertenue, T. pallidum subsp. endemicum, and T. carateum are the agents of the endemic treponematoses yaws, bejel (or endemic syphilis), and pinta, respectively. All human treponematoses share remarkable similarities in pathogenesis and clinical manifestations, consistent with the high genetic and antigenic relatedness of their etiological agents. Distinctive features have been identified in terms of age of acquisition, most common mode of transmission, and capacity for invasion of the central nervous system and fetus, although the accuracy of these purported differences is debated among investigators and no biological basis for these differences has been identified to date. In 2012, the World Health Organization (WHO) officially set a goal for yaws eradication by 2020. This challenging but potentially feasible endeavor is favored by the adoption of oral azithromycin for mass treatment and the currently focused distribution of yaws and endemic treponematoses and has revived global interest in these fascinating diseases and their causative agents.

  17. Foot-and-mouth disease in British deer: transmission of virus to cattle, sheep and deer.

    Gibbs, E P; Herniman, K A; Lawman, M J; Sellers, R F

    1975-06-28

    After exposure for two hours to cattle with foot-and-mouth disease, each of the five species of deer found in the British countryside became infected. Clinical disease was typical and severe in the roe and muntjac deer, with some animals dying, less severe in the sika deer and usually subclinical in the fallow and red deer. Each species transmitted disease to its own species and to cattle and sheep. The amounts of virus present in the blood, and in oesophageal/pharyngeal samples and excreted as an aerosol during the course of the infection in the deer were similar to those recorded for the sheep and cattle in the same experiment. The fallow and sika deer commonly carried virus in the pharynx beyond 28 days after exposure; some red deer also became carriers. In epidemics of foot-and-mouth disease in the UK, it is likely that deer would have such intimate contact with farm animals as occurred in this study. The natural behavior of free-living deer in the UK suggests that, although the five species are susceptible to foot-and-mouth disease, they are unlikely to be an important factor in the maintenance and transmission of the virus during an epidemic of foot-and-mouth disease in domestic livestock.

    2015-01-01

    Full Text Available Lyme borreliosis, caused by the bacterium, Borrelia burgdorferi, is an emerging vector-borne infectious disease in Canada. According to the Public Health Agency of Canada (PHAC, by the year 2020, 80% of Canadians will live in Lyme endemic areas. An understanding of the association of Ixodes scapularis, the main vector of Lyme disease, with it hosts is a fundamental component in assessing changes in the spatial distribution of human risk for Lyme disease. Through the application of Geographic Information System (GIS mapping methods and spatial analysis techniques, this study examines the population dynamics of the black-legged Lyme tick and its primary host, the white-tailed deer, in eastern Ontario, Canada. By developing a habitat suitability model through a GIS-based multi-criteria decision making (MCDM analysis, the relationship of the deer habitat suitability map was generated and the results were compared with deer harvest data. Tick submission data collected from two public health units between 2006 and 2012 were used to explore the relationship between endemic ticks and deer habitat suitability in eastern Ontario. The positive correlation demonstrated between the deer habitat suitability model and deer harvest data allows us to further analyze the association between deer habitat and black-legged ticks in our study area. Our results revealed that the high tick submission number corresponds with the high suitability. These results are useful for developing management strategies that aim to prevent Lyme from becoming a threat to public health in Canada. Further studies are required to investigate how tick survival, behaviour and seasonal activity may change with projected climate change.

    Sika deer is of great commercial value because their antlers are used in tonics and alternative medicine and their meat is healthy and delicious. The goal of this study was to generate transcript sequences from sika deer for functional genomic analyses and to identify the transcripts that demonstrate tissue-specific, age-dependent differential expression patterns. These sequences could enhance our understanding of the molecular mechanisms underlying sika deer growth and development. In the present study, we performed de novo transcriptome assembly and profiling analysis across ten tissue types and four developmental stages (juvenile, adolescent, adult, and aged) of sika deer, using Illumina paired-end tag (PET) sequencing technology. A total of 1,752,253 contigs with an average length of 799 bp were generated, from which 1,348,618 unigenes with an average length of 590 bp were defined. Approximately 33.2 % of these (447,931 unigenes) were then annotated in public protein databases. Many sika deer tissue-specific, age-dependent unigenes were identified. The testes have the largest number of tissue-enriched unigenes, and some of them were prone to develop new functions for other tissues. Additionally, our transcriptome revealed that the juvenile-adolescent transition was the most complex and important stage of the sika deer life cycle. The present work represents the first multiple tissue transcriptome analysis of sika deer across four developmental stages. The generated data not only provide a functional genomics resource for future biological research on sika deer but also guide the selection and manipulation of genes controlling growth and development.

  1. Radiocesium contamination of roe-deers kidneys

    Radiocesium (137Cs and 134Cs) have been measured in kidneys of 48 roe-deers shot in November 1986 on several Belgian game reserves. A large variability of the contamination levels was observed from one site to another due to significant differences in radioactive deposits after the Chernobyl accident. As direct deposit measurements are lacking, the radioactivity accumulated in bramble leaves could be a good indicator of internal roe-deer contamination. (Author)

  2. Parasites, diseases, and health status of sympatric populations of sika deer and white-tailed deer in Maryland and Virginia.

    Davidson, W R; Crow, C B

    1983-10-01

    In July 1981, investigations on parasites, diseases, and herd health status were conducted on sympatric populations of sika deer (Cervus nippon) and white-tailed deer (Odocoileus virginianus) from Blackwater National Wildlife Refuge (Maryland) and Chincoteague National Wildlife Refuge (Virginia) on the Delmarva Peninsula. Five adult deer of each species were collected from each location and subjected to thorough necropsy examinations and laboratory tests. White-tailed deer at both locations harbored protozoan, helminth, and arthropod parasites typically associated with this species throughout the southeastern United States. In contrast, sika deer at both locations harbored only light burdens of ticks, chiggers, and sarcocysts. Serologic tests for antibodies to seven infectious disease agents revealed evidence of exposure to bovine virus diarrhea (BVD) virus, infectious bovine rhinotracheitis virus, and parainfluenza3 virus in white-tailed deer, but only BVD virus in sika deer. At both locations the general health status of sika deer was superior to that of white-tailed deer. PMID:6644934

    1994-12-31

    The Rocky Mountain Arsenal is a fenced, 6,900-ha Superfund site under remediation by the US Army and the Shell Oil Company. A variety of environmental contaminants including organochlorine pesticides, metals, and nerve-gas-production by-products are in the soil or in the water on the site. The authors evaluated the health of 18 radio-collared deer (13 mule deer [Odocoileus hemionus] and 5 white-tailed deer [O. virginianus]) collected by gunshot. Prior to collection, more than 4,000 locations of the 18 deer were plotted during a period of more than 2 years. Blood samples from the euthanized animals were collected for serologic, hematologic, and contaminant evaluations. Necropsies were preformed and tissues collected for histopathologic examinations and environmental contaminants analyses. Results indicate that the physical conditions of the mule deer were fair/good and of the white-tailed deer were good. Antibody prevalence against epizootic hemorrhagic disease serotype 2 was 85% and bovine virus diarrhea 56%. Two mule deer had severe testicular atrophy, and one of these animals also had antler deformities. Three mule deer had alopecia with dermatitis and hyperkeratosis. Results of heavy metal, and organochlorine pesticide analyses from blood and tissue samples and other analyses will be presented.

  10. Authenticity control of game meat products--a single method to detect and quantify adulteration of fallow deer (Dama dama), red deer (Cervus elaphus) and sika deer (Cervus nippon) by real-time PCR.

    Druml, Barbara; Grandits, Stephanie; Mayer, Walter; Hochegger, Rupert; Cichna-Markl, Margit

    2015-03-01

    This contribution presents a single real-time PCR assay allowing the determination of the deer content (the sum of fallow deer (Dama dama), red deer (Cervus elaphus) and sika deer (Cervus nippon)) in meat products to detect food adulteration. The PCR assay does not show cross-reactivity with 20 animal species and 43 botanical species potentially contained in game meat products. The limit of quantification is 0.5% for fallow deer and red deer and 0.1% for sika deer. The deer content in meat products is determined by relating the concentration obtained with the deer PCR assay to that obtained with a reference system which amplifies mammals and poultry DNA. The analysis of binary meat mixtures with pork, a meat mixture containing equal amounts of fallow deer, red deer and sika deer in pork and a model game sausage showed that the quantification approach is very accurate (systematic error generally <25%).

  11. Deer density and disease prevalence influence transmission of Chronic Wasting Disease in White-tailed Deer

    Samuel, Michael D.; Richards, Bryan J.; Storm, Daniel J.; Rolley, Robert E.; Shelton, Paul; Nicholas S. Keuler; Timothy R. Van Deelen

    2013-01-01

    Host-parasite dynamics and strategies for managing infectious diseases of wildlife depend on the functional relationship between disease transmission rates and host density. However, the disease transmission function is rarely known for free-living wildlife, leading to uncertainty regarding the impacts of diseases on host populations and effective control actions. We evaluated the influence of deer density, landscape features, and soil clay content on transmission of chronic wasting disease (CWD) in young (tailed deer (Odocoileus virginianus) in south-central Wisconsin, USA. We evaluated how frequency-dependent, density-dependent, and intermediate transmission models predicted CWD incidence rates in harvested yearling deer. An intermediate transmission model, incorporating both disease prevalence and density of infected deer, performed better than simple density- and frequency-dependent models. Our results indicate a combination of social structure, non-linear relationships between infectious contact and deer density, and distribution of disease among groups are important factors driving CWD infection in young deer. The landscape covariates % deciduous forest cover and forest edge density also were positively associated with infection rates, but soil clay content had no measurable influences on CWD transmission. Lack of strong density-dependent transmission rates indicates that controlling CWD by reducing deer density will be difficult. The consequences of non-linear disease transmission and aggregation of disease on cervid populations deserves further consideration.

    2015-01-01

    Full Text Available Little is known about the prevalence of Toxoplasma gondii in wild life, particularly game animals in Poland. Meat juice collected during the 2009/2010 and 2010/2011 hunting seasons from 552 red deer (Cervus elaphus, 367 wild boars (Sus scrofa and 92 roe deer (Capreolus capreolus was tested for T. gondii antibodies using the multi-species ID Screen Toxoplasmosis Indirect kit (IDvet, Montpellier, France. Antibodies to T. gondii were detected in 24.1% of red deer (95% CI: 20.7%, 27.8%, 37.6% of wild boar (95% CI: 32.8%, 42.7% and 30.4% of roe deer (95% CI: 22.0%, 40.5%. To the authors’ best knowledge, this is the first epidemiological report of T. gondii prevalence in red deer, roe deer and wild boars in Poland. T. gondii is present in wildlife animal tissues and consumption of the game may be a potential source of infection for humans.

  17. Neurology of endemic skeletal fluorosis

    Reddy D

    2009-01-01

    Full Text Available Endemic skeletal fluorosis is widely prevalent in India and is a major public health problem. The first ever report of endemic skeletal fluorosis and neurological manifestation was from Prakasam district in Andhra Pradesh in the year 1937. Epidemiological and experimental studies in the endemic areas suggest the role of temperate climate, hard physical labor, nutritional status, presence of abnormal concentrations of trace elements like strontium, uranium, silica in water supplies, high fluoride levels in foods and presence of kidney disease in the development of skeletal fluorosis. Neurological complications of endemic skeletal fluorosis, namely radiculopathy, myelopathy or both are mechanical in nature and till date the evidence for direct neurotoxicity of fluoride is lacking. Prevention of the disease should be the aim, knowing the pathogenesis of fluorosis. Surgery has a limited role in alleviating the neurological disability and should be tailored to the individual based on the imaging findings.

  18. The nature of serpentine endemism.

    Anacker, Brian L

    2014-02-01

    Serpentine soils are a model system for the study of plant adaptation, speciation, and species interactions. Serpentine soil is an edaphically stressful, low productivity soil type that hosts stunted vegetation and a spectacular level of plant endemism. One of the first papers on serpentine plant endemism was by Arthur Kruckeberg, titled "Intraspecific variability in the response of certain native plant species to serpentine soil." Published in the American Journal of Botany in 1951, it has been cited over 100 times. Here, I review the context and content of the paper, as well as its impact. On the basis of the results of reciprocal transplant experiments in the greenhouse, Kruckeberg made three important conclusions on the nature of serpentine plant endemism: (1) Plants are locally adapted to serpentine soils, forming distinct soil ecotypes; (2) soil ecotypes are the first stage in the evolutionary progression toward serpentine endemism; and (3) serpentine endemics are restricted from more fertile nonserpentine soils by competition. Kruckeberg's paper inspired a substantial amount of research, especially in the three areas reviewed here: local adaptation and plant traits, speciation, and the interaction of climate and soil in plant endemism. In documenting soil ecotypes, Kruckeberg identified serpentine soils as a potent selective factor in plant evolution and helped establish serpentine soils as a model system in evolution and ecology.

  19. Somatic Chromosomes of the Bornean Sambar Deer and Rusa Deer Interspecific Hybrids

    Ismail Idris

    2009-01-01

    Full Text Available Problem statement: Hybridization has potential benefits to the Malaysian farmed deer industries in terms of increased growth rate and increased proportion of muscle and an improved alignment of feed supply and annual energy requirement. Species or subspecies of different chromosome constitution could mate to produce healthy hybrid offspring in a normal ratio of males and females. If any of the hybrid offspring were sterile, the sterile offspring would be the heterogametic offspring. The study investigated the use of chromosome banding method to detect chromosomal variation and to define the chromosome homology and the possibility of the Bornean Sambar deer (Cervus unicolor brookei and Rusa deer (Cervus timorensis hybrids to reproduce. Approach: Samples were collected from the Livestock Breeding Station, Sabrang, Keningau, Sabah, East Malaysia. The animals studied consisted of two deer subspecies namely the Bornean Sambar deer, Rusa deer and their hybrids. The karyotypes of the Bornean Sambar deer, Rusa deer and their F1 hybrids have been investigated by solid giemsa staining, G-banding and Ag-NOR banding techniques. Results: Rusa and Bornean Sambar have different chromosome number; 60 and 62 respectively, but share the same fundamental number of chromosome arm, 70. The hybrids have 2n = 61, consisting of 9 metacentric to submetacentric autosomes and 24 pairs of acrocentric autosomes with two acrocentrics and one submetacentric chromosome being unpaired. The morphology of the sex chromosomes in the F1 hybrids was similar to that of the parental species. The Ag-NOR pattern and the conventional Giemsa staining of chromosomes were effective as markers in the characterization of the karyotypes of the parental lines and hybrids because of the presence of active NORs on different chromosomes of different species. G-band, in contrast, showed complete homology in the presence of euchromatic bands and heterochromatin blocks respectively on each chromosome

    2012-07-01

    Full Text Available Abstract Background In the Eastern and Upper Midwestern regions of North America, Ixodes scapularis (L. is the most abundant tick species encountered by humans and the primary vector of B. burgdorferi, whereas in the southeastern region Amblyomma americanum (Say is the most abundant tick species encountered by humans but cannot transmit B. burgdorferi. Surveys of Borreliae in ticks have been conducted in the southeastern United States and often these surveys identify B. lonestari as the primary Borrelia species, surveys have not included Arkansas ticks, canines, or white-tailed deer and B. lonestari is not considered pathogenic. The objective of this study was to identify Borrelia species within Arkansas by screening ticks (n = 2123, canines (n = 173, and white-tailed deer (n = 228 to determine the identity and locations of Borreliae endemic to Arkansas using PCR amplification of the flagellin (flaB gene. Methods Field collected ticks from canines and from hunter-killed white-tailed were identified to species and life stage. After which, ticks and their hosts were screened for the presence of Borrelia using PCR to amplify the flaB gene. A subset of the positive samples was confirmed with bidirectional sequencing. Results In total 53 (21.2% white-tailed deer, ten (6% canines, and 583 (27.5% Ixodid ticks (252 Ixodes scapularis, 161 A. americanum, 88 Rhipicephalus sanguineus, 50 Amblyomma maculatum, 19 Dermacentor variabilis, and 13 unidentified Amblyomma species produced a Borrelia flaB amplicon. Of the positive ticks, 324 (22.7% were collected from canines (151 A. americanum, 78 R. sanguineus, 43 I. scapularis, 26 A. maculatum, 18 D. variabilis, and 8 Amblyomma species and 259 (37.2% were collected from white-tailed deer (209 I. scapularis, 24 A. maculatum, 10 A. americanum, 10 R. sanguineus, 1 D. variabilis, and 5 Amblyomma species. None of the larvae were PCR positive. A majority of the flaB amplicons were homologous with B

  1. Country, cover or protection: what shapes the distribution of red deer and roe deer in the Bohemian Forest Ecosystem?

    Marco Heurich

    Full Text Available The Bohemian Forest Ecosystem encompasses various wildlife management systems. Two large, contiguous national parks (one in Germany and one in the Czech Republic form the centre of the area, are surrounded by private hunting grounds, and hunting regulations in each country differ. Here we aimed at unravelling the influence of management-related and environmental factors on the distribution of red deer (Cervus elaphus and roe deer (Capreolus capreolus in this ecosystem. We used the standing crop method based on counts of pellet groups, with point counts every 100 m along 218 randomly distributed transects. Our analysis, which accounted for overdispersion as well as zero inflation and spatial autocorrelation, corroborated the view that both human management and the physical and biological environment drive ungulate distribution in mountainous areas in Central Europe. In contrast to our expectations, protection by national parks was the least important variable for red deer and the third important out of four variables for roe deer; protection negatively influenced roe deer distribution in both parks and positively influenced red deer distribution in Germany. Country was the most influential variable for both red and roe deer, with higher counts of pellet groups in the Czech Republic than in Germany. Elevation, which indicates increasing environmental harshness, was the second most important variable for both species. Forest cover was the least important variable for roe deer and the third important variable for red deer; the relationship for roe deer was positive and linear, and optimal forest cover for red deer was about 70% within a 500 m radius. Our results have direct implications for the future conservation management of deer in protected areas in Central Europe and show in particular that large non-intervention zones may not cause agglomerations of deer that could lead to conflicts along the border of protected, mountainous areas.

    2015-11-01

    Forest musk deer is one of the large-scale farming musk deer animals with the largest population at the same time. The male musk deer can secrete valuable medicines, which has high medicinal and economic value. Due to the loss of habitat and indiscriminate hunting, the numbers of wild population specie and the distribution have been drastically reduced. Therefore, in-depth understanding of the molecular genetics progress of forest musk deer will pave a way for musk deer protection and breeding. In this review, the progress associated with the molecular marker, genetic classification, artificial breeding, musk secretion and disease in past decades were reviewed, in order to provide a theoretical basis for subsequent molecular genetic researches in forest musk deer.

  3. Motivations of female Black Hills deer hunters

    Gigliotti, Larry M.; Covelli Metcalf, Elizabeth

    2016-01-01

    State fish and wildlife agencies are particularly interested in attracting female participation because of the potential to offset declining participation in hunting. Understanding female hunters’ motivations will be critical for designing effective recruitment and retention programs for women hunters. Although female participation in hunting is increasing, males still outnumber females by about tenfold. Gender differences in deer hunters were explored by comparing ratings of eight motivations (social, nature, excitement, meat, challenge, trophy, extra hunting opportunity, and solitude). Hunter types were defined by hunters’ selection of the most important motivation for why they like Black Hills deer hunting. Overall, females and males were relatively similar in their ratings of the eight motivations, and we found 85% gender similarity in the selection of the most important motivation. Women were slightly more motivated by the food aspect of the hunt while men placed slightly more value on the hunt as a sporting activity.

  4. A method for testing handgun bullets in deer

    Courtney, Michael; Courtney, Amy

    2007-01-01

    Using service handguns to test bullets in deer is problematic because of velocity loss with range and accuracy giving sub-optimal shot placement. An alternate method is presented using a scoped muzzleloader shooting saboted handgun bullets to allow precise (within 2" in many cases) shot placement for studying terminal ballistics in a living target. Deer are baited to a known range and path obstructions are used to place the deer broadside to the shooter. Muzzleloading powder charges provide a...

  6. Babesias of red deer (Cervus elaphus in Ireland

    Zintl Annetta

    2011-01-01

    Full Text Available Abstract Blood samples were obtained from 38 wild red deer (Cervus elaphus at two sites in Ireland and subjected to PCR analysis of the 18S rRNA gene followed by sequencing. Two fragments of the 18S rRNA gene were generated by two different PCR protocols and subsequent sequencing suggested that at least six of the deer were infected by a babesia that, in those loci, is indistinguishable from Babesia divergens, an important tick-borne pathogen of cattle and of zoonotic significance. Additionally, a B. odocoilei-like parasite was detected in three samples and a babesia that did not match any sequences in the GenBank database was found in five samples. Neither B. capreoli nor B. venatorum (EU1 were found. There have been several reports of B. divergens occurring in deer species, including red deer, roe deer (Capreolus capreolus and reindeer (Rangifer tarandus. However, in view of recent re-sequencing of bovine-origin samples deposited previously in GenBank, it is unlikely that any of these sequences from deer are B. divergens. The present study describes the only deer piroplasm detected so far that shows complete identity with B. divergens, in just over half of the 18S rRNA gene. The entire gene of this deer parasite should be analysed and transmission experiments undertaken before the infectivity of B. divergens for red deer can be confirmed.

    This paper reports an outbreak of trypanosomiasis due to Trypanosoma evansi in Java deer (Cervus timorensis) on a government deer farm in Lenggong, Perak. Seventeen adult female Java deer were found dead within a week. Symptoms of dullness, inappetence, anaemia, anorexia, respiratory distress and recumbency were seen prior to death in the infected Java deer. Beside trypanosomiasis, other parasitic infections such as theileriosis, helminthiasis and ectoparasite infestation were also recorded. Post mortem results showed generalized anaemia in most animals with isolated cases of jaundice. There was no significant finding with respect to bacteriological and viral investigations.

    The genetic basis of susceptibility to chronic wasting disease (CWD) in free-ranging cervids is of great interest. Association studies of disease susceptibility in free-ranging populations, however, face considerable challenges including: the need for large sample sizes when disease is rare, animals of unknown pedigree create a risk of spurious results due to population admixture, and the inability to control disease exposure or dose. We used an innovative matched case–control design and conditional logistic regression to evaluate associations between polymorphisms of complement C1q and prion protein (Prnp) genes and CWD infection in white-tailed deer from the CWD endemic area in south-central Wisconsin. To reduce problems due to admixture or disease-risk confounding, we used neutral genetic (microsatellite) data to identify closely related CWD-positive (n = 68) and CWD-negative (n = 91) female deer to serve as matched cases and controls. Cases and controls were also matched on factors (sex, location, age) previously demonstrated to affect CWD infection risk. For Prnp, deer with at least one Serine (S) at amino acid 96 were significantly less likely to be CWD-positive relative to deer homozygous for Glycine (G). This is the first characterization of genes associated with the complement system in white-tailed deer. No tests for association between any C1q polymorphism and CWD infection were significant at p < 0.05. After controlling for Prnp, we found weak support for an elevated risk of CWD infection in deer with at least one Glycine (G) at amino acid 56 of the C1qC gene. While we documented numerous amino acid polymorphisms in C1q genes none appear to be strongly associated with CWD susceptibility.

  9. Epidemiology, diagnostics, and management of tuberculosis in domestic cattle and deer in New Zealand in the face of a wildlife reservoir.

    2015-06-01

    The control of tuberculosis (TB) in cattle and farmed deer in New Zealand has been greatly influenced by the existence of a wildlife reservoir of Mycobacterium bovis infection, principally the Australian brushtail possum (Trichosurus vulpecula). The reduction in possum numbers in areas with endemic M. bovis infection through vigorous vector control operations has been a major contributor to the marked reduction in the number of infected cattle and farmed deer herds in the past two decades. Management of TB in cattle and farmed deer in New Zealand has involved a combination of vector control, regionalisation of diagnostic testing of cattle and deer herds, abattoir surveillance and movement control from vector risk areas. Accurate diagnosis of infected cattle and deer has been a crucial component in the control programme. As the control programme has evolved, test requirements have changed and new tests have been introduced or test interpretations modified. Subspecific strain typing of M. bovis isolates has proved to be a valuable component in the epidemiological investigation of herd breakdowns to identify whether the source of infection was domestic livestock or wildlife. New initiatives will include the use of improved models for analysing diagnostic test data and characterising disease outbreaks leading to faster elimination of infection from herds. The introduction of the National Animal Identification Tracing programme will allow better risk profiling of individual herds and more reliable tracing of animal movements. TB in cattle and farmed deer in New Zealand can only be controlled by eliminating the disease in both domestic livestock and the wildlife reservoir. PMID:24992203

  10. Intranasal inoculation of white-tailed deer (Odocoileus virginianus with lyophilized chronic wasting disease prion particulate complexed to montmorillonite clay.

    Tracy A Nichols

    Full Text Available Chronic wasting disease (CWD, the only known prion disease endemic in wildlife, is a persistent problem in both wild and captive North American cervid populations. This disease continues to spread and cases are found in new areas each year. Indirect transmission can occur via the environment and is thought to occur by the oral and/or intranasal route. Oral transmission has been experimentally demonstrated and although intranasal transmission has been postulated, it has not been tested in a natural host until recently. Prions have been shown to adsorb strongly to clay particles and upon oral inoculation the prion/clay combination exhibits increased infectivity in rodent models. Deer and elk undoubtedly and chronically inhale dust particles routinely while living in the landscape while foraging and rutting. We therefore hypothesized that dust represents a viable vehicle for intranasal CWD prion exposure. To test this hypothesis, CWD-positive brain homogenate was mixed with montmorillonite clay (Mte, lyophilized, pulverized and inoculated intranasally into white-tailed deer once a week for 6 weeks. Deer were euthanized at 95, 105, 120 and 175 days post final inoculation and tissues examined for CWD-associated prion proteins by immunohistochemistry. Our results demonstrate that CWD can be efficiently transmitted utilizing Mte particles as a prion carrier and intranasal exposure.

    Lyme Disease is caused by the bacterial pathogen Borrelia burgdorferi, and is transmitted by the tick-vector Ixodes scapularis. It is the most prevalent arthropod-borne disease in the United States. To determine the seroprevalence of B. burgdorferi antibodies in white-tailed deer (Odocoileus virginianus) from Texas, we analyzed serum samples (n = 1493) collected during the 2001-2015 hunting seasons, using indirect ELISA. Samples with higher sero-reactivity (0.803 and above) than the negative control group (0.662) were further tested using a more specific standardized western immunoblot assay to rule out false positives. Using ELISA, 4.7% of the samples were sero-reactive against B. burgdorferi, and these originated in two eco-regions in Texas (Edwards Plateau and South Texas Plains). However, only 0.5% of the total samples were sero-reactive by standardized western immunoblot assay. Additionally, both ELISA and standardized western immunoblot assay results correlated with an increased incidence in human Lyme Disease cases reported in Texas. This is the first longitudinal study to demonstrate fluctuation in sero-reactivity of white-tailed deer to B. burgdorferi sensu stricto antigens in southern United States. Future ecological and geographical studies are needed to assess the environmental factors governing the prevalence of Lyme Disease in non-endemic areas of the southern United States. PMID:27366674

  12. The effect of terrain and female density on survival of neonatal white-tailed deer and mule deer fawns.

    2016-07-01

    Juvenile survival is a highly variable life-history trait that is critical to population growth. Antipredator tactics, including an animal's use of its physical and social environment, are critical to juvenile survival. Here, we tested the hypothesis that habitat and social characteristics influence coyote (Canis latrans) predation on white-tailed deer (Odocoileus virginianus) and mule deer (O. hemionus) fawns in similar ways during the neonatal period. This would contrast to winter when the habitat and social characteristics that provide the most safety for each species differ. We monitored seven cohorts of white-tailed deer and mule deer fawns at a grassland study site in Alberta, Canada. We used logistic regression and a model selection procedure to determine how habitat characteristics, climatic conditions, and female density influenced fawn survival during the first 8 weeks of life. Fawn survival improved after springs with productive vegetation (high integrated Normalized Difference Vegetation Index values). Fawns that used steeper terrain were more likely to survive. Fawns of both species had improved survival in years with higher densities of mule deer females, but not with higher densities of white-tailed deer females, as predicted if they benefit from protection by mule deer. Our results suggest that topographical variation is a critical resource for neonates of many ungulate species, even species like white-tailed deer that use more gentle terrain when older. Further, our results raise the possibility that neonatal white-tailed fawns may benefit from associating with mule deer females, which may contribute to the expansion of white-tailed deer into areas occupied by mule deer.

  15. Welfare of farmed deer in New Zealand. 1. Management practices.

    Pollard, J C; Wilson, P R

    2002-12-01

    This review summarises research of management practices that potentially impact on the welfare of farmed deer. The processes of capture and initial domestication of feral deer caused many welfare problems but are now essentially complete in New Zealand. The health and production status of farmed deer, and readily visible indicators of their welfare are generally good, although preventive medicines and optimum management practices have not been universally adopted. Research into social behaviour, effects of yarding, weaning, mating, calving, shelter, shade and nutrition has identified ways of improving the welfare of farmed deer and has provided recommendations for deer industry quality assurance programmes. Research has identified transport design and practices that minimise the impact of transport on deer welfare and reduce carcass wastage caused by bruising during transport. Time in lairage prior to slaughter should be minimised and electrical stunning is a humane method of slaughter. Ongoing research is needed on management practices and farm environments to further improve the welfare of farmed deer, consistent with the goals of the New Zealand deer industry and its proactive approach to date.

Over one year, we collect feces samples every month from different habitat types (e.g., heath, marsh, meadow, open forests and coniferous plantation) within the park. DNA barcoding can not only tell us which plants are consumed but...... also in which proportions. We intend to uncover the variation in deer diet over a year and among different habitats and how supplementary fodder influences the diet preference. The results will contribute to a better understanding of deer management as well as how deer grazing can be used as a tool in...

  1. Can coyotes affect deer populations in Southeastern North America?

    Kilgo, J., C.; Ray, H., Scott; Ruth, Charles; Miller, Karl, V.

    2010-07-01

    ABSTRACT The coyote (Canis latrans) is a recent addition to the fauna of eastern North America, and in many areas coyote populations have been established for only a decade or two. Although coyotes are known predators of white-tailed deer (Odocoileus virginianus) in their historic range, effects this new predator may have on eastern deer populations have received little attention. We speculated that in the southeastern United States, coyotes may be affecting deer recruitment, and we present 5 lines of evidence that suggest this possibility. First, the statewide deer population in South Carolina has declined coincident with the establishment and increase in the coyote population. Second, data sets from the Savannah River Site (SRS) in South Carolina indicate a new mortality source affecting the deer population concurrent with the increase in coyotes. Third, an index of deer recruitment at SRS declined during the period of increase in coyotes. Fourth, food habits data from SRS indicate that fawns are an important food item for coyotes during summer. Finally, recent research from Alabama documented significant coyote predation on fawns there. Although this evidence does not establish cause and effect between coyotes and observed declines in deer recruitment, we argue that additional research should proactively address this topic in the region. We identified several important questions on the nature of the deer–coyote relationship in the East.

  4. Bovine virus diarrhea virus in free-living deer from Denmark.

    Nielsen, S S; Roensholt, L; Bitsch, V

    2000-07-01

    Free-living deer are suggested as a possible source of infection of cattle with bovine virus diarrhea (BVD) virus. To examine this hypothesis blood samples from 476 free-living deer were collected during two different periods and tested for BVD virus and antibody in Denmark. In 1995-96, 207 animals were tested. These included 149 roe deer (Capreolus capreolus), 29 fallow deer (Dama dama), 20 red deer (Cervus elaphus) and one sika deer (Cervus sika). For the remaining eight animals no species information was available. In 1998-99, 269 animals were tested including 212 roe deer and 57 red deer. The animals were selected from areas with a relatively high prevalence of cattle herds with a BVD persistent infection status in 1997 and 1998. All 207 samples from 1995-96 were found antibody-negative except two samples from red deer. Only 158 of the 207 samples were tested for virus and were all found negative. Of the 269 samples from 1998-99 all but one were antibody negative. The positive sample was from a red deer. All samples were virus-negative. It appears that BVD infection does not occur in roe deer in Denmark. The presence of antibody in a few red deer from various districts in Jutland probably results from cattle to deer transmission, rather than spread among deer. Hence, the possibility of free-living deer as a source of infection for cattle in Denmark seems to be remote. PMID:10941751

    We demonstrate by means of simple, noninvasive methods (analysis of satellite images, field observations, and measuring “deer beds” in snow) that domestic cattle (n = 8,510 in 308 pastures) across the globe, and grazing and resting red and roe deer (n = 2,974 at 241 localities), align their body axes in roughly a north–south direction. Direct observations of roe deer revealed that animals orient their heads northward when grazing or resting. Amazingly, this ubiquitous phenomenon does not seem...

  7. Possible species differences between Sarcocystis from mule deer and cattle.

    Hudkins-Vivion, G; Kistner, T P; Fayer, R

    1976-01-01

    In preliminary studies with Sarcocystis from bovine (Bos taurus) and mule deer (Odocoileus hemionus hemionus), a coccidia-free laboratory dog (Canis familiaris) and captive coyote (Canis latrans) were fed flesh from a local Sarcocystis-infected bovine and later flesh from an infected mule deer from Eastern Oregon. Sporocysts were passed in the feces of both canine hosts 10-15 days after ingestion of infected meat. There was a statistical difference in the size of sporocysts derived from bovine and deer. It was concluded that the Sarcocystis from bovine and mule deer probably constitute distinct species with a life cycle dependent on the respective ruminant host and a canine host. PMID:815572

  8. A method for testing handgun bullets in deer

    Courtney, M; Courtney, Amy; Courtney, Michael

    2007-01-01

    Using service handguns to test bullets in deer is problematic because of velocity loss with range and accuracy giving sub-optimal shot placement. An alternate method is presented using a scoped muzzleloader shooting saboted handgun bullets to allow precise (within 2" in many cases) shot placement for studying terminal ballistics in a living target. Deer are baited to a known range and path obstructions are used to place the deer broadside to the shooter. Muzzleloading powder charges provide a combination of muzzle velocity and velocity loss due to air resistance for a given ballistic coefficient that produce impact velocities corresponding to typical pistol velocities. With readily available sabots, this approach allows for testing of terminal ballistics of .355, .357, .40, .429, .45, and .458 caliber bullets with two muzzleloaders (.45 and .50 caliber). Examples are described demonstrating the usefulness of testing handgun bullets in deer for acoustic shooting event reconstruction, understanding tissue damag...

  11. Mycobacterium bovis infection in a captive herd of Sika deer.

    Mirsky, M L; Morton, D; Piehl, J W; Gelberg, H

    1992-05-15

    Infection with Mycobacterium bovis was diagnosed in a small privately owned herd of Sika deer. After postmortem examination of a deer with progressive pulmonary disease, diagnosis of infection with M bovis was confirmed by bacteriologic culture. The 2 remaining deer in this herd were euthanatized, necropsied, and confirmed to be infected with M bovis. Three cats in contact with the deer were also euthanatized and necropsied. One of these cats had lesions suggestive of mycobacterial infection in the colon and mesenteric lymph nodes. Infection of this cat with M bovis was not confirmed by bacterial culture. Mycobacteriosis, infrequently encountered in clinical veterinary practice, may be confused with disease caused by other infective agents or neoplasia. The zoonotic potential of these bacteria and a recent increase in human tuberculosis warrants continued surveillance of companion and food animal populations for mycobacterial infection.

  12. Deer predation on leaf miners via leaf abscission

    Yamazaki, Kazuo; Sugiura, Shinji

    2008-03-01

    The evergreen oak Quercus gilva Blume sheds leaves containing mines of the leaf miner Stigmella sp. (Lepidoptera: Nepticulidae) earlier than leaves with no mines in early spring in Nara, central Japan. The eclosion rates of the leaf miner in abscised and retained leaves were compared in the laboratory to clarify the effects of leaf abscission on leaf miner survival in the absence of deer. The leaf miner eclosed successfully from both fallen leaves and leaves retained on trees. However, sika deer ( Cervus nippon centralis Kishida) feed on the fallen mined leaves. Field observations showed that deer consume many fallen leaves under Q. gilva trees, suggesting considerable mortality of leaf miners due to deer predation via leaf abscission. This is a previously unreported relationship between a leaf miner and a mammalian herbivore via leaf abscission.

  14. Reproductive biology of the pampas deer (Ozotoceros bezoarticus: a review

    Olazabal Daniel

    2008-06-01

    Full Text Available Abstract The pampas deer (Ozotoceros bezoarticus is a South American grazing deer which is in extreme danger of extinction. Very little is known about the biology of the pampas deer. Moreover, most information has not been published in peer-reviewed scientific journals, and is only available in local publications, theses, etc. Therefore, our aim was to update and summarize the available information regarding the reproductive biology of the pampas deer. Moreover, in most sections, we have also included new, unpublished information. Detailed descriptions are provided of the anatomy of both the female and the male reproductive tract, puberty onset, the oestrous cycle and gestational length. Birthing and the early postpartum period are described, as are maternal behaviour and early fawn development, seasonal distribution of births, seasonal changes in male reproduction and antler cycle, reproductive behaviour, semen collection, and cryopreservation. Finally, an overview is given and future directions of research are proposed.

  15. Model for predicting 90Sr levels in mule deer

    A model was developed to estimate the strontium-90 levels in male mule deer (Odocoileus hemionus hemionus) from known 90Sr intake rates. The model was formulated on results from a study on the effects of age and season on Sr kinetics in mule deer. Captive deer of various ages, at selected times throughout the year, were given acute oral doses of 85SrCl2 and whole body counted to determine the retention function. A two-component exponential equation was used to mathematically describe the retention of 85Sr. The average for the slopes of the short component (1.09 day-1) corresponded very closely with the mean retention time for insoluble material in the gastrointestinal tract. For male deer, the value of the fractional intercept of the long component generally increased with age. The fractional intercepts also varied with the time of year the deer was administered the 85Sr, ranging from an average of 0.0539 during antler dormancy to 0.154 during periods of antler growth. The average of the observed values for the slope of the long component was 0.00365 day-1 for all deer. For the bucks, the slope of the long component was observed to decrease with age at time of spiking and to vary from a minimum for those spiked during antler dormancy to a maximum for those spiked during the antler growth period. There were no apparent effects of age and season on the kinetics of Sr in female deer. The model was developed to describe the uptake and retention of chronically ingested Sr. Due to the variations in the fractional intercept and slope of the long component, both associated with skeletal bone remodeling, the model utilized varying parameters. The predicted values were compared with those observed in a wild deer population and the close agreement added credibility to the coefficients of the total body retention equations utilized in the model

  19. Assessing Vehicle-Related Mortality of Mule Deer in Utah

    Olson, Daniel D.

    2013-01-01

    Roads are essential in modern societies, but as populations grow and traffic volumes rise, roads will continue to be built and expanded. As a result, the effects that roads have on wildlife will likely intensify, making it imperative that managers understand those effects so mitigation can be directed accordingly. In Utah, considerable areas of mule deer (Odocoileus hemionus) habitat have been bisected by roads. Mule deer are commonly involved in vehicle collisions and there is concern that r...

  1. Will Culling White-Tailed Deer Prevent Lyme Disease?

    Kugeler, K J; Jordan, R A; Schulze, T L; Griffith, K S; Mead, P S

    2016-08-01

    White-tailed deer play an important role in the ecology of Lyme disease. In the United States, where the incidence and geographic range of Lyme disease continue to increase, reduction of white-tailed deer populations has been proposed as a means of preventing human illness. The effectiveness of this politically sensitive prevention method is poorly understood. We summarize and evaluate available evidence regarding the effect of deer reduction on vector tick abundance and human disease incidence. Elimination of deer from islands and other isolated settings can have a substantial impact on the reproduction of blacklegged ticks, while reduction short of complete elimination has yielded mixed results. To date, most studies have been conducted in ecologic situations that are not representative to the vast majority of areas with high human Lyme disease risk. Robust evidence linking deer control to reduced human Lyme disease risk is lacking. Currently, there is insufficient evidence to recommend deer population reduction as a Lyme disease prevention measure, except in specific ecologic circumstances. PMID:26684932

    2014-07-01

    Full Text Available In this study, the effects of melatonin (MT on superovulation and reproductive hormones (melatonin, follicle-stimulating hormone (FSH, luteinizing hormone (LH and PRL were investigated in female sika deer. Different doses (40 or 80 mg/animal of melatonin were subcutaneously implanted into deer before the breeding season. Exogenous melatonin administration significantly elevated the serum FSH levels at the time of insemination compared with levels in control animals. During superovulation, the serum LH levels in donor sika deer reached their highest values (7.1 ± 2.04 ng/mL at the point of insemination, compared with the baseline levels (4.98 ± 0.07 ng/mL in control animals. This high level of LH was sustained until the day of embryo recovery. In contrast, the serum levels of PRL in the 80 mg of melatonin-treated group were significantly lower than those of control deer. The average number of corpora lutea in melatonin-treated deer was significantly higher than that of the control (p < 0.05. The average number of embryos in the deer treated with 40 mg of melatonin was higher than that of the control; however, this increase did not reach significant difference (p > 0.05, which may be related to the relatively small sample size. In addition, embryonic development in melatonin-treated groups was delayed.

  3. Investigation of anatomical anomalies in Hanford Site mule deer

    Tiller, B.L.; Cadwell, L.L.; Poston, T.M. [and others

    1997-03-01

    Rocky Mountain mule deer (Odocoileus hemionus hemionus), common residents of the Hanford Site, are an important part of the shrub-steppe ecosystem as well as being valued for aesthetics and hunting. Because mule deer have been protected from hunting on the Site for 50 years, the herd has developed unique population characteristics, including a large number of old animals and males with either large or atypically developed antlers, in contrast to other herds in the semi-arid regions of the Northwest. Hanford Site mule deer have been studied since 1991 because of the herd`s unique nature and high degree of public interest. A special study of the mule deer herd was initiated in 1993 after observations were made of a relatively large number of male deer with atypical, velvet-covered antlers. This report specifically describes our analyses of adult male deer found on the Site with atypical antlers. The report includes estimates of population densities and composition; home ranges, habitat uses, and dietary habits; natural and human-induced causes of mortality; and the herd`s overall health and reproductive status.

  8. Endemism analysis of Neotropical Pentatomidae (Hemiptera, Heteroptera

    Augusto Ferrari

    2010-12-01

    Full Text Available The definition of areas of endemism is central to studies of historical biogeography, and their interrelationships are fundamental questions. Consistent hypotheses for the evolution of Pentatomidae in the Neotropical region depend on the accuracy of the units employed in the analyses, which in the case of studies of historical biogeography, may be areas of endemism. In this study, the distribution patterns of 222 species, belonging to 14 Pentatomidae (Hemiptera genera, predominantly neotropical, were studied with the Analysis of Endemicity (NDM to identify possible areas of endemism and to correlate them to previously delimited areas. The search by areas of endemism was carried out using grid-cell units of 2.5° and 5° latitude-longitude. The analysis based on groupings of grid-cells of 2.5° of latitude-longitude allowed the identification of 51 areas of endemism, the consensus of these areas resulted in four clusters of grid-cells. The second analysis, with grid-cells units of 5° latitude-longitude, resulted in 109 areas of endemism. The flexible consensus employed resulted in 17 areas of endemism. The analyses were sensitive to the identification of areas of endemism in different scales in the Atlantic Forest. The Amazonian region was identified as a single area in the area of consensus, and its southeastern portion shares elements with the Chacoan and Paraná subregions. The distribution data of the taxa studied, with different units of analysis, did not allow the identification of individual areas of endemism for the Cerrado and Caatinga. The areas of endemism identified here should be seen as primary biogeographic hypotheses.

  9. Molecular identification of the Cryptosporidium deer genotype in the Hokkaido sika deer (Cervus nippon yesoensis) in Hokkaido, Japan.

    2016-04-01

    The protozoan Cryptosporidium occurs in a wide range of animal species including many Cervidae species. Fecal samples collected from the Hokkaido sika deer (Cervus nippon yesoensis), a native deer of Hokkaido, in the central, western, and eastern areas of Hokkaido were examined by polymerase chain reaction (PCR) to detect infections with Cryptosporidium and for sequence analyses to reveal the molecular characteristics of the amplified DNA. DNA was extracted from 319 fecal samples and examined with PCR using primers for small-subunit ribosomal RNA (SSU-rRNA), actin, and 70-kDa heat shock protein (HSP70) gene loci. PCR-amplified fragments were sequenced and phylogenetic trees were created. In 319 fecal samples, 25 samples (7.8 %) were positive with SSU-rRNA PCR that were identified as the Cryptosporidium deer genotype. Among Cryptosporidium-positive samples, fawns showed higher prevalence (16.1 %) than yearlings (6.4 %) and adults (4.7 %). The result of Fisher's exact test showed a statistical significance in the prevalence of the Cryptosporidium deer genotype between fawn and other age groups. Sequence analyses with actin and HSP70 gene fragments confirmed the SSU-rRNA result, and there were no sequence diversities observed. The Cryptosporidium deer genotype appears to be the prevalent Cryptosporidium species in the wild sika deer in Hokkaido, Japan. PMID:26687968

  11. Removal of cesium from red deer meat

    The effect was studied of marinading on the reduction of cesium radionuclide activity in red deer meat contaminated by ingestion of feed containing 134Cs+137Cs from radioactive fallout following the Chernobyl accident. Two types of marinade were studied, viz., a vinegar infusion and a vinegar infusion with an addition of vegetables and spices. The meat was chopped to cubes of about 1.5 cm in size and the marinading process took place at temperatures of 5 and 11 degC. The drop of cesium content in the meat was determined by gamma spectrometry at given time intervals. The replacement of the marinade and the duration of the process were found to maximally affect efficiency. If the solution was not replaced, about 80% of cesium radionuclides were removed after seven hours of marinading. With one replacement of the infusion the drop in 134Cs+137Cs radioactivity amounted to up to 90% after seven hours of marinading. No effects were shown of vegetable additions to the vinegar infusion and of the change in temperature from 5 to 11 degC on the efficiency of the process. (author). 3 tabs., 6 refs

  17. Wolf, Canis lupus, visits towhite-tailed deer, Odocoileus virginianus, summer ranges: Optimal foraging?

    Demma, D.J.; Mech, L.D.

    2009-01-01

    We tested whether Wolf (Canis lupus) visits to individual female White-tailed Deer (Odocoileus virginianus) summer ranges during 2003 and 2004 in northeastern Minnesota were in accord with optimal-foraging theory. Using GPS collars with 10- to 30-minute location attempts on four Wolves and five female deer, plus eleven VHF-collared female deer in the Wolves' territory, provided new insights into the frequency of Wolf visits to summer ranges of female deer. Wolves made a mean 0.055 visits/day to summer ranges of deer three years and older, significantly more than their 0.032 mean visits/day to ranges of two-year-old deer, which generally produce fewer fawns, and most Wolf visits to ranges of older deer were much longer than those to ranges of younger deer. Because fawns comprise the major part of the Wolf's summer diet, this Wolf behavior accords with optimal-foraging theory.

  18. Minimizing capture-related stress on white-tailed deer with a capture collar

    DelGiudice, G.D.; Kunkel, K.E.; Mech, L.D.; Seal, U.S.

    1990-01-01

    We compared the effect of 3 capture methods for white-tailed deer (Odocoileus virginianus) on blood indicators of acute excitement and stress from 1 February to 20 April 1989. Eleven adult females were captured by Clover trap or cannon net between 1 February and 9 April 1989 in northeastern Minnesota [USA]. These deer were fitted with radio-controlled capture collars, and 9 deer were recaptured 7-33 days later. Trapping method affected serum cortisol (P capture-collared deer (0.54 .+-. 0.07 [SE] .mu.g/dL) compared to Clover-trapped (4.37 .+-. 0.69 .mu.g/dL) and cannon-netted (3.88 .+-. 0.82 .mu.g/dL) deer. Capture-collared deer were minimally stressed compared to deer captured by traditional methods. Use of the capture collar should permit more accurate interpretation of blood profiles of deer for assessement of condition and general health.

  19. Polonium assimilation and retention in mule deer and pronghorn antelope

    Excretion kinetics and tissue distribution of polonium-210 in mule deer and pronghorn were studied. Each animal in a captive herd of 7 mule deer and 2 pronghorn received an intraruminal injection of 4.4 μCi of polonium chloride. Feces and urine were collected periodically over a 43-day period and daily excretion rate for each pathway was regressed as a function of time. Assimilation fractions of 0.40 and 0.51 were calculated for mule deer (n=2) and 0.60 for a pronghorn. Body burden retention functions were calculated from integrated excretion rate functions. Polonium burdens in muscle, liver, and kidney were calculated as a fraction of body burden from serially-sacrificed animals. Background tissue burdens in mule deer were comparable to those of other ruminants reported in the literature. Hypothetical cases were assumed which combined feeding rate of mule deer, forage concentrations of polonium, retention function, tissue burden fraction, and human intake to estimate human radiation dose. 26 references

  1. Hunter perceptions and acceptance of alternative deer management regulations

    Cornicelli, L.; Fulton, D.C.; Grund, M.D.; Fieberg, J.

    2011-01-01

    Wildlife managers are often confronted with a policy paradox where a majority of the public supports an outcome, but there is no agreement on specific management strategies to achieve this outcome. Previous research has also reported a link between regulatory acceptance, hunter satisfaction, and hunter participation rates. Thus, human dimensions research aimed at understanding hunter motivations and behavior is needed for effective management. In 2005, we surveyed Minnesota (USA) deer hunters (n = 6,000; 59% response) to evaluate attitudes regarding alternative deer (Odocoileus virginianus) harvest regulations. We also conducted a series of forced choice experiments in which respondents were asked to select an option from a list of representative regulations that might be adopted to achieve a particular deer management goal. Specifically, we modeled 5 deer population scenarios ranging from low populations with high buck-harvest rates to populations 50% over goal density. Our results indicate that hunters preferred different regulations depending on the population scenario, but generally preferred antler-point restrictions and disliked limiting buck licenses through a lottery. We also found consistency among scenarios, in that a small percentage of respondents indicated they would not hunt if regulations were changed. The results from this study should help wildlife managers design deer harvest regulations that are both acceptable to hunters and achieve management objectives. ?? 2011 The Wildlife Society.

    2014-01-01

    Spatial gradients in human activity, coyote activity, deer activity, and deer herbivory provide an unusual type of evidence for a trophic cascade. Activity of coyotes, which eat young mule deer (fawns), decreased with proximity to a remote biological field station, indicating that these predators avoided an area of high human activity. In contrast, activity of adult female deer (does) and intensity of herbivory on palatable plant species both increased with proximity to the station and were p...

  10. An Assessment of Agricultural Damage Caused by Red Deer (Cervus elaphus L.and Fallow Deer (Dama dama L. in Southwest England

    Charles John Wilson

    2009-12-01

    Full Text Available The impact of deer grazing on agricultural grassland and cereal crops was assessed at two locations with medium to high deer densities in the Exmoor area of southwest England. Red deer impact on early spring grazing was measured at one site by comparing samples of herbage cut from inside and outside deer-proof exclosure cages, just prior to turn out of livestock, on 1 March 1989. Fallow deer impact on first-cut silage grass production was similarly measured using exclosure cages at a second site by cutting samples on 31 May 1990 and on 6 June 1995. In addition, impact of fallow deer on cereal crops was assessed at this site by measuring sample grain yields from areas of the crop used or unused by deer in 1995 (winter wheat, 1996 (winter barley and 1997 (winter wheat. Significant dry matter yield losses were recorded for red deer impact on spring grazing in 1989 (14.5% and for fallow deer impact on first-cut silage (15.9% in 1995 but not in 1990. In 1995 a small but significant yield loss (7.1% was recorded for winter wheat at the fallow deer site but no loss in cereal yield was recorded in 1996 or 1997. These assessments, carried out in response to complaints about deer damage, suggest that the impacts of deer in this area, where they occur at relatively high density, are only moderate. This highlights the need for careful assessment of cost-benefits when considering deer management strategies to reduce perceived agricultural damage.

  11. Vaccination with BM86, subolesin and akirin protective antigens for the control of tick infestations in white tailed deer and red deer.

    2012-01-01

    Red deer (Cervus elaphus) and white-tailed deer (Odocoileus virginianus) are hosts for different tick species and tick-borne pathogens and play a role in tick dispersal and maintenance in some regions. These factors stress the importance of controlling tick infestations in deer and several methods such as culling and acaricide treatment have been used. Tick vaccines are a cost-effective alternative for tick control that reduced cattle tick infestations and tick-borne pathogens prevalence while reducing the use of acaricides. Our hypothesis is that vaccination with vector protective antigens can be used for the control of tick infestations in deer. Herein, three experiments were conducted to characterize (1) the antibody response in red deer immunized with recombinant BM86, the antigen included in commercial tick vaccines, (2) the antibody response and control of cattle tick infestations in white-tailed deer immunized with recombinant BM86 or tick subolesin (SUB) and experimentally infested with Rhipicephalus (Boophilus) microplus, and (3) the antibody response and control of Hyalomma spp. and Rhipicephalus spp. field tick infestations in red deer immunized with mosquito akirin (AKR), the SUB ortholog and candidate protective antigen against different tick species and other ectoparasites. The results showed that deer produced an antibody response that correlated with the reduction in tick infestations and was similar to other hosts vaccinated previously with these antigens. The overall vaccine efficacy was similar between BM86 (E=76%) and SUB (E=83%) for the control of R. microplus infestations in white-tailed deer. The field trial in red deer showed a 25-33% (18-40% when only infested deer were considered) reduction in tick infestations, 14-20 weeks after the first immunization. These results demonstrated that vaccination with vector protective antigens could be used as an alternative method for the control of tick infestations in deer to reduce tick populations

    Full Text Available The objectives of the research were to study on habitat distribution and the diversity of forest plants as feed resources of mouse deer (Tragulus javanicus and barking deer (Muntiacus muntjak was conducted in Nature Preserve of Nusakambangan. Preferred Habitat of mouse deer is the dense of bushes with many fallen dry leaves which seemingly they use for their mattress cover as well as the places with bush dense of zalacca palm and generally not far from the river. While the barking deer prefers the dense of bushes on the edges of forest with coarse grass grow there. Forest plants as feed resources for mouse deer and barking deer found in this research consist of 34 species grouped in 21 families.

  13. NEW FOSSIL VERTEBRATE REMAINS FROM SAN GIOVANNI DI SINIS (LATE PLEISTOCENE, SARDINIA: THE LAST MAUREMYS (REPTILIA, TESTUDINES IN THE CENTRAL MEDITERRANEAN

    FRANCESCO CHESI

    2007-07-01

    Full Text Available New fossil vertebrates from the most representative Upper Pleistocene section (Tyrrhenian, MIS 5e of the outcrop of San Giovanni di Sinis (Oristano, Sardinia are here reported and described. The fossils, although scarce and fragmentary, document the occurrence of a terrapin (Mauremys sp. and the endemic Sardinian deer (Praemegaceros cazioti. Significant is the occurrence of the terrapin because it is the youngest representative of the genus in the central Mediterranean area where it is extinct at present. The Late Pleistocene extinction of Mauremys in Italy follows the same pattern of other Mediterranean reptiles, in being in some cases delayed on the islands. A comparison of the modern range of Mauremys and that of the pond turtle, Emys, as well as of their past ranges as evidenced by the fossil record, might suggest that some sort of thermophily (at least during pre-hatching stages characterized the former taxon and is responsible for its past and present distribution. SHORT NOTE

  15. Evaluating immunocontraception for managing suburban white-tailed deer in Irondequoit, New York

    Rudolph, B.A.; Porter, W.F.; Underwood, H.B.

    2000-01-01

    Immunocontraception is frequently proposed as an alternative to lethal removal of females for deer management. However, little information is available for evaluating the potential of applying immunocontraceptives to free-ranging populations. Our objectives were to estimate effort required to apply porcine zona pellucida (PZP) to individual deer and assess the utility of using immunocontraception to control growth of deer populations. The study was conducted in a 43-km2 suburban community with about 400 deer. Effort per deer was measured as time required to capture and mark deer, and then to apply booster immunocontraceptive treatments by remote injection. Estimates of numbers of females to treat to control population growth were based on the generalized sustained-yield (SY) model adapted for contraception of females. The SY curve was calibrated using data on deer abundance acquired from aerial population surveys and nutritional condition of females removed by a concurrent culling program. Effort was influenced by 4 factors: deer population density, approachability of individual deer, access to private and public land, and efficacy of the contraceptive treatment. Effort and deer density were inversely related. Cumulative effort for treatment increased exponentially because some deer were more difficult to approach than others. Potential of using immunocontraception at low deer population densities (<25% ecological carrying capacity) is limited by the interaction of the proportion of breeding-age females in the population and treatment efficacy, as well as encounter rates. Immunocontraception has the best potential for holding suburban deer populations between 30 and 70% of ecological carrying capacity, but is likely to be useful only in localized populations when the number of females to be treated is small (e.g., <200 deer).

  16. Analysis of radionuclide concentrations and movement patterns of Hanford-site mule deer

    From 1980 through 1982, the movements of 37 radio-collared mule deer (Odocoileus hemionus) were monitored for periods of 3 to 17 months on the Handord Site in southcentral Washington. The objectives were to compare radionuclide concentrations in deer residing near the 200 Area waste management sites with concentrations in deer occupying areas remote from waste management sites and to document movement patterns of Hanford Site deer with particular emphasis on offsite movements. Cesium-137 in deer muscle and liver and 90Sr concentrations in deer bone were statistically higher in deer living near the 200 Area than in control animals. During this study, the highest concentrations of 137Cs and 90Sr in 200 Area deer were in those individuals residing in or immediately adjacent to radiation zones. Cesium-137 and 90Sr concentrations were more variable in deer residing near the 200 Area than in control animals, where only background (fallout) levels were observed. Movement patterns of Hanford site deer were analyzed to determine home range size and usage. The average home range was 0.39 +- 27 km2. In addition, ten (27%) of the monitored deer made offsite movements during the study period. While most of these movements were made in the spring and summer, some fall and winter movements were noted. It was estimated that approximately 8% (95% confidence interval is from 0 to 21%) of the Hanford deer herd is harvested each year. As a result of the low harvest rate, the Hanford deer herd appears to have a disproportionate number of older animals, with 24% of the 17 examined deer older than 10.5 years

  2. Sarcocystosis in wild red deer (Cervus elaphus) in Patagonia, Argentina.

    Reissig, Elizabeth Chang; Moré, Gastón; Massone, Adriana; Uzal, Francisco A

    2016-05-01

    Sarcocystis spp. are protozoan parasites with a heteroxenous life cycle, which produce cysts in the muscle of herbivorous animals. In these animal species, sarcocystosis is frequently asymptomatic, although it may occur with high prevalence. Seven Sarcocystis spp. have been described in red deer (Cervus elephus). The aim of this study was to determine the prevalence of sarcocystosis, and to perform the morphological and molecular characterization of Sarcocystis spp. found in wild red deer of the Nahuel Huapi National Park (NHNP), Patagonia, Argentina. Full necropsies of 62 red deer killed by hunters in the NHNP and neighboring areas were performed. Samples of heart and skeletal muscle were examined histologically and selected samples were also examined by transmission electron microscopy (TEM), PCR and sequencing. Sarcocystis spp. thin walled cysts were detected in 62 % (38/62) of heart, and in 22 % (3/14) of skeletal muscle samples examined histologically. TEM revealed a smooth and thin cyst wall (≤1 μm), with scarce and separated ribbon-like protrusions. A total of three partial and one full 18S ribosomal RNA (rRNA) gene sequences were obtained, and showed the highest identity (≥99 %) with Sarcocystis taeniata, a species described in moose (Alces alces). The morphological and molecular results indicate that red deer in Argentina are frequently infected with S. taeniata, a species for which the definitive host is unknown. The present results also confirm that Sarcocystis spp. using cervids as intermediate host are not host-specific. Further studies are needed to improve the epidemiological knowledge of Sarcocystosis in red deer. PMID:26779923

    To address the need to preserve current genetic diversity before it is lost forever; further studies to adapt assisted reproductive technologies to various endangered species are needed, among other things. Roe deer (Capreolus capreolus), an over abundant wild deer, can serve as model species to develop or improve sperm cryopreservation of threatened or endangered deer species. The aim of this study was to compare the ability of three diluents (Berliner Cryomedium [BC]; Tris, citric acid, glucose [TCG]; TES, Tris, glucose) to support chilling, cryopreservation (with 5% glycerol; G) and postthaw incubation (at 22 °C and 37 °C) of roe deer spermatozoa collected by electroejaculation. Berliner Cryomedium was the diluent that better preserved roe deer spermatozoa during refrigeration, able to maintain motility for at least 14 days, longer than the other extenders. BC + G was the extender of choice for cryopreservation, showing higher viability compared with TCG + G (66.7 ± 3.4 vs. 54.5 ± 6.5; P < 0.05) and higher level of acrosome integrity compared with TES, Tris, glucose + G (79.4 ± 3.4 vs. 67.9 ± 5.0; P < 0.05). Maintaining the samples at 22 °C after thawing presented higher values in various parameters compared with 37 °C. The knowledge gained through this study can potentially act as a preliminary step toward development of new protocols to help increase the reproductive success of biologically similar, yet endangered, wild species.

  4. Pampas deer (Ozotoceros bezoarticus courtship and mating behavior

    Morales-Piñeyrúa Jéssica T

    2012-10-01

    Full Text Available Abstract Background Pampas deer, Ozotoceros bezoarticus (Linnaeus 1758, is a South American grazing deer categorized as "near threatened". However, knowledge about pampas deer behavior including courtship and mating is scarce and incomplete. The aim of this study was to characterize the courtship and mating behavior of the pampas deer (Ozotoceros bezoarticus, an endangered species from South America. Methods We performed focal observations of 5 males allocated at the Estación de Cría de Fauna Autóctona Cerro Pan de Azúcar, Uruguay, 4 times a day from 5 to 20 minutes each time on a daily basis from February to May. During that period we recorded all courtship and mating behaviors, as well as quantified the frequency of the specific behaviors shown. As mating were rarely observed, we recorded that behavior when it was observed in the context of other studies performed in the same population during the following 2 years. Results During the observation period we recorded 928 courtships and 5 mating periods. In addition, we recorded 10 more matings performed during other studies, totaling 15. The duration of each mating calculated from the 15 recordings was 3.9 ± 0.4 s, and the total period of female receptivity (from first to last mating acceptance was 8.2 ± 1.1 min. Main observed courtship behaviors in males were “chase” and “ostentation”, while the most observed close to mating were “chinning”, “raised head” and “anogenital sniffing”. The most observed behaviors in females during the mating period were “vulva exhibition” and “move away”. Conclusion This is the first detailed report in pampas deer mating behavior. Estrus lasted only 8 min accepting only 3 short copulations per estrus. However, female behavior during courtship can be characterized as highly proceptive.

  5. Clinical significance of neurocysticercosis in endemic villages

    Cerebral cysticercosis is the main cause of late-onset epilepsy in most developing countries. Data on the neuroepidemiology of cysticercosis in endemic populations is scarce. In an endemic village on the northern coast of Peru, 49 individuals with neurological symptomatology (41 epileptic and 8 non-epileptic) were screened for antibodies to Taenia solium, using a serum electroimmuno transfer blot assay. Fifteen subjects were seropositive, 14 (34%) of those with epilepsy but only one (13%) of those who were non-epileptic. A history of passing proglottides was associated with positive serology. Thirteen of the 15 seropositive individuals underwent cerebral computed tomography; only 7 (54%) were abnormal. A randomly selected sample of 20 pigs from the village was also tested, and 6 (30%) were seropositive. This study demonstrated the importance of cysticercosis in the aetiology of epilepsy in endemic villages and the close relationship between porcine and human infection

    Effective delivery of vaccines and other pharmaceuticals to wildlife populations is needed when zoonotic diseases pose a risk to public health and natural resources or have considerable economic consequences. The objective of our study was to develop a bait-distribution strategy for potential delivery of oral bovine tuberculosis (bTB) vaccine to white-tailed deer (Odocoileus virginianus) where deer are reservoirs for the disease. During 17 February and 2 March 2011, we created a grid of experimental bait stations (n = 64) on Sandhill Wildlife Management Area, Wisconsin, USA, to assess station densities needed to attract and deliver placebo baits to free-ranging white-tailed deer and look for associations among deer density, number of bait stations per deer, and bait consumption. We placed 1 L of commercially available alfalfa cubes at bait stations 652 m apart, and monitored stations with motion-activated cameras for 5 days to document visitation and consumption by deer and nontarget species. Deer discovered 38% of all bait stations within 37 hr, on average (SE = 3.91 hr), and consumed variable amounts of bait at each station. Deer were documented in 94% of all photographs of wildlife at bait stations. We found no correlation between bait consumption and deer density or the number of bait stations per deer. We provide the first information on use of baits by free-ranging deer and nontarget wildlife to eventually vaccinate deer against bTB at a landscape level. The results of this study can further the development of strategies in delivery of pharmaceuticals to free-ranging white-tailed deer.

  7. Weak population structure in European roe deer (Capreolus capreolus and evidence of introgressive hybridization with Siberian roe deer (C. pygargus in northeastern Poland.

    Juanita Olano-Marin

    Full Text Available We investigated contemporary and historical influences on the pattern of genetic diversity of European roe deer (Capreolus capreolus. The study was conducted in northeastern Poland, a zone where vast areas of primeval forests are conserved and where the European roe deer was never driven to extinction. A total of 319 unique samples collected in three sampling areas were genotyped at 16 microsatellites and one fragment (610 bp of mitochondrial DNA (mtDNA control region. Genetic diversity was high, and a low degree of genetic differentiation among sampling areas was observed with both microsatellites and mtDNA. No evidence of genetic differentiation between roe deer inhabiting open fields and forested areas was found, indicating that the ability of the species to exploit these contrasting environments might be the result of its phenotypic plasticity. Half of the studied individuals carried an mtDNA haplotype that did not belong to C. capreolus, but to a related species that does not occur naturally in the area, the Siberian roe deer (C. pygargus. No differentiation between individuals with Siberian and European mtDNA haplotypes was detected at microsatellite loci. Introgression of mtDNA of Siberian roe deer into the genome of European roe deer has recently been detected in eastern Europe. Such introgression might be caused by human-mediated translocations of Siberian roe deer within the range of European roe deer or by natural hybridization between these species in the past.

  8. Pathophysiology of white-tailed deer vaccinated with porcine zona pellucida immunocontraceptive

    Curtis, P.D.; Richmond, M.E.; Miller, L.A.; Quimby, F.W.

    2007-01-01

    White-tailed deer (n = 14 treated, n = 7 control) were examined postmortem to identify any possible pathophysiology resulting from PZP immunocontraception vaccination. Deer were treated twice in 1997; given a booster in 1998, with six being revaccinated in September 2000. Granulomas were found at injection sites of most deer, even 2 years post-treatment. Eosinophilic oophoritis occurred in 6 of 8 (75%) deer vaccinated in 1998, and 3 of 6 (50%) revaccinated in 2000. The 2000 revaccinates without oophoritis, had significantly fewer normal secondary follicles than control females (P = 0.03), and deer in the1998 treatment group (P = 0.04). PZP immunocontraceptive vaccine elicited ovarian pathologies in deer similar to those observed in other species. ?? 2007 Elsevier Ltd. All rights reserved.

  11. Cutaneous fibroma in the roe deer (Capreolus capreolus

    Kureljušić Branislav

    2009-01-01

    Full Text Available Fibromas present very frequent skin neoplasms in different species of wild game of the family Cervidae. Viral etiology of skin neoplasms was proven in certain species of wild game from this family, with the most frequent diagnoses being: fibromas, ossifying fibromas, fibrosarcomas, multiple neurofibromatosis, fibropapillomas, and papillomas. The diagnozed tumor in the roe deer had the histological characteristics of a polimorphous fibroblast, which is not the case with domestic animals. This finding can be considered as a characteristic of fibromas in animals of the family Cervidae. Solitary fibroma or multiple fibroma (fibromatosis does not present a significant cause of deer deaths, but they cause concern among hunters who are in direct contact with them. Although fibromas do not lead to spoilage of game meat, they are esthetically repellent and people are reluctant to consume meat of such game.

  12. Red deer synchronise their activity with close neighbours

    Sean A. Rands

    2014-04-01

    Full Text Available Models of collective animal behaviour frequently make assumptions about the effects of neighbours on the behaviour of focal individuals, but these assumptions are rarely tested. One such set of assumptions is that the switch between active and inactive behaviour seen in herding animals is influenced by the activity of close neighbours, where neighbouring animals show a higher degree of behavioural synchrony than would be expected by chance. We tested this assumption by observing the simultaneous behaviour of paired individuals within a herd of red deer Cervus elaphus. Focal individuals were more synchronised with their two closest neighbours than with the third closest or randomly selected individuals from the herd. Our results suggest that the behaviour of individual deer is influenced by immediate neighbours. Even if we assume that there are no social relationships between individuals, this suggests that the assumptions made in models about the influence of neighbours may be appropriate.

    2011-12-01

    Full Text Available This syndrome is a shock-like hyper metabolic myopathy triggered in susceptible animals by stress. Capture myopathy (C.M. is a commonly occurring condition in mammals following trapping and ransportation. In this case 12 to 24 hours after transportation of red deer (Cevus elaphus and wild goats (Capra ibex clinical signs such as: muscular tremor, ataxia, recumbency, hyperthermia, tachycardia, hyperventilation and red brown urine observed. According to symptoms Capture myoparthy was diagnosed Treatment was ineffective on one red deer and one wild goat. Necropsy findings of dead animals were included: hyperemia, petechial hemorrhage in pericardium and heart muscle, pale foci of leg and heart muscles and red brown urine in bladder. This case report represents the attention to Capture myopathy in wild animals and particular caution that should be exercised in capturing and handling of these animals.

    2009-09-01

    A captive fallow deer (Dama dama) in a zoo was spontaneously poisoned after consumption of Sida carpinifolia. The paddock where cervids were kept was severely infested by S. carpinifolia. The deer developed a neurological syndrome characterized by muscular weakness, intention tremors, visual and standing-up deficits, falls, and abnormal behavior and posture. Because a severe mandibular fracture and the consequent deteriorating condition, it was euthanized. Main microscopic findings were swelling and multifocal cytoplasmic vacuolation in the Purkinje cells. The cytoplasm of multiple cells of the cerebellum, especially the Purkinje cells, stained with the lectins Concanavalia ensiformis, Triticum vulgaris, and succinylated Triticum vulgaris. Diagnostic possibilities such as bovine diarrhea virus, rabies, and transmissible spongiform encephalopathy were excluded. The report focuses on the risk of maintaining S. carpinifolia populations in zoo enclosures of wild herbivores. PMID:19746879

    Hyper-herbivory following predator removal is a global issue. Across North America and Europe, increasing deer numbers are affecting biodiversity and human epidemiology, but effectiveness of deer management in heterogeneous landscapes remains poorly understood. In forest habitats in Europe, deer numbers are rarely assessed and management is mainly based on impacts. Even where managed areas achieve stable or improving impact levels, the extent to which they act as sinks or persist as sources e...

    Adiaspiromycosis is a pulmonary infection caused by the soil fungi, Emmonsia crescens and E. parva. It primarily affects small mammals and can range from an asymptomatic condition to fatal disseminated disease. We detected a granuloma containing fungal spherules, which were morphologically consistent with the adiaspores of E. crescens in the lungs of a female Hokkaido sika deer. This is the first reported case of adiaspiromycosis involving a cervid in the world. PMID:25787928

    Stefano Mattioli

    2003-10-01

    Full Text Available Abstract The biometry, demography and genetics of red deer Cervus elaphus of Mesola Wood (NE Italy, are presented and discussed in relation to the conservation of this population. Modest body size, low stature, oversimplified antlers and a low reproductive performance characterise red deer from Mesola Wood. The mitochondrial genome showed a private haplotype, different from other red deer in Italy and central Europe. The uniqueness of this nucleus and its biogeographic importance make a long-term conservation plan particularly urgent. Management measures such as fallow deer reduction, winter feeding and pasture mowing were tested, giving promising results. The physical condition of the animals improved, calf and adult mortality declined, and a few cases of antlers with bez tine or crown were reported in this study after four decades. Riassunto Il Cervo della Mesola: caratteristiche fisiche, dinamica di popolazione e prospettive di conservazione La biometria, la demografia e la genetica del cervo Cervus elaphus del Gran Bosco della Mesola (Italia nord-orientale, vengono presentate e discusse in relazione alla salvaguardia di questa popolazione. Il cervo della Mesola risulta caratterizzato dalle modeste dimensioni corporee, dalla struttura semplificata dei palchi e da un basso rendimento riproduttivo. L'analisi del genoma mitocondriale ha evidenziato un aplotipo privato, diverso da quello degli altri cervi italiani e centroeuropei. L'unicità di questo nucleo e la sua importanza biogeografica rendono particolarmente urgente un piano di conservazione a lungo termine. Sono stati verificati interventi gestionali quali la riduzione numerica dei daini, il foraggiamento invernale e lo sfalcio delle superfici a pascolo, con risultati promettenti. Le condizioni fisiche degli animali sono migliorate, la mortalità tra i piccoli e gli adulti è diminuita, e sono stati registrati alcuni

  12. Improved Oocyte Isolation and Embryonic Development of Outbred Deer Mice

    Jung Kyu Choi; Xiaoming He

    2015-01-01

    In this study, we improved the protocol for isolating cumulus-oocyte complexes (COCs) from the outbred deer mice by using only one hormone (instead of the widely used combination of two hormones) with reduced dose. Moreover, we identified that significantly more metaphase II (MII) oocytes could be obtained by supplementing epidermal growth factor (EGF) and leukemia inhibition factor (LIF) into the previously established medium for in vitro maturation (IVM) of the COCs. Furthermore, we overcam...

  13. Predator evasion by white-tailed deer fawns

    Grovenburg, Troy W.; Monteith, Kevin L.; Klaver, Robert W.; Jenks, Jonathan A.

    2012-01-01

    Despite their importance for understanding predator–prey interactions, factors that affect predator evasion behaviours of offspring of large ungulates are poorly understood. Our objective was to characterize the influence of selection and availability of escape cover and maternal presence on predator evasion by white-tailed deer, Odocoileus virginianus, fawns in the northern Great Plains, U.S.A. We observed 45 coyote, Canis latrans, chases of fawns, and we participated in 83 human chases of fawns during 2007–2009, of which, 19 and 42 chases, respectively, ended with capture of the fawn. Evasive techniques used by fawns were similar for human and coyote chases. Likelihood of a white-tailed deer fawn escaping capture, however, was influenced by deer group size and a number of antipredator behaviours, including aggressive defence by females, initial habitat and selection of escape cover, all of which were modified by the presence of parturient females. At the initiation of a chase, fawns in grasslands were more likely to escape, whereas fawns in forested cover, cultivated land or wheat were more likely to be captured by a coyote or human. Fawns fleeing to wetlands and grasslands also were less likely to be captured compared with those choosing forested cover, wheat and cultivated land. Increased probability of capture was associated with greater distance to wetland and grassland habitats and decreased distance to wheat. Use of wetland habitat as a successful antipredator strategy highlights the need for a greater understanding of the importance of habitat complexity in predator avoidance.

  14. Genetic analysis of evolutionary relationships among deer (subfamily Cervinae).

    Emerson, B C; Tate, M L

    1993-01-01

    The evolutionary relationships among 10 taxa of deer from the four genera of the subfamily Cervinae (Cervus, Elaphurus, Axis, and Dama) were examined by a comparison of their electrophoretic types for 22 proteins. We analyzed the data using both phenetic and cladistic methods and found that the genera of the Cervinae were not monophyletic. The genus Cervus was split into two distinct groups with red deer, wapiti (C. elaphus ssp.), and sika (C. nippon) in one clade and sambar (C. unicolor) and rusa (C. timorensis) in another. There was a close genetic relationship between the genus Elaphurus and the red deer, wapiti, sika group, whereas sambar and rusa were more similar to members of the genera Dama and Axis than to the other members of their own genus. These findings contrast with the taxonomy of the species that is based largely on studies of comparative morphology. Our samples (n = 5) showed fixed allelic differences between wapiti and red, wapiti and sika, and red and sika samples at 3, 6, and 7 loci, respectively. Analysis of these protein loci in a wider range of C. elaphus and C. nippon subspecies could resolve debate over the evolutionary relationships of these taxa. PMID:8340615

    2009-01-01

    The aim of this study was to document the behavior of captive alpine musk deer and to determine if daily behavior patterns varied between females and males. From August 2002 to January 2003, focal sampling was used to observe 32 adult captive alpine musk deer (13 female and 19 male) at Xinglongshan Musk Deer Farm (XMDF), Xinglongshan National Nature Reserve, Gansu Province. Results indicated similar behavior patterns for males and females, with only two out of 12 recorded behaviors showing significant sex differences. In comparison to females, males rested for a longer duration and exhibited tail pasting more frequently. This study also provided the first recording of tail pasting by female musk deer.

  16. Age determination in roe deer - a new approach to tooth wear evaluated on known age individuals

    Høye, Toke Thomas

    2006-01-01

    A novel, simple, and objective method is presented for ageing roe deer Capreolus capreolus (Linnaeus, 1758) evaluated on 471 lower jaws from roe deer of known age (351 with permanent premolars). It is based on tooth eruption patterns and presence/absence of wear characters in jaws from roe deer...... originate from two separated Danish roe deer populations exposed to contrasting habitats, but no difference in wear rate is found between populations. Thus, previous concern about the validity of age determination methods based on tooth wear may have been overstated. The findings demonstrate that objective...

    1975-06-01

    Red, sika, fallow, roe and muntjac deer adapted to captivity in experimental units designed for working with foot-and-mouth disease. The red, sika and fallow deer readily accepted rolled oats and hay as their staple diet. This diet was replaced for the roe and muntjac deer with flaked maize, calf starter pellets and green browse. Etorphine/acepromazine ans xylazine were found to be suitable sedatives for detailed examination of the tongue and oral cavity of the various species of deer and gave adequate analgesia for the inoculation and collection of virus samples.

  18. Complement-mediated killing of Borrelia garinii--bactericidal activity of wild deer serum.

    Isogai, E; Kamewaka, Y; Isogai, H; Kimura, K; Fujii, N; Nishikawa, T

    1994-01-01

    The susceptibility of Borrelia garinii to fresh wild deer sera was determined by incubating strain SIKA2 at 10% serum concentration for 1 hr at 37 C in an in vitro bactericidal assay. Each serum showed bactericidal effects at various levels. The effect was dependent on the concentration of antibody to the spirochetes. Complement was essential in the bactericidal assay because the inactivated deer serum showed greatly decreased activity. Our results suggest that B. garinii is sensitive to deer serum, in the presence of antibody and the bactericidal effect is important for preventing Lyme disease in wild sika deer. PMID:7854216

  19. Distribution of Mycobacterium ulcerans in buruli ulcer endemic and non-endemic aquatic sites in Ghana.

    Heather R Williamson

    Full Text Available Mycobacterium ulcerans, the causative agent of Buruli ulcer, is an emerging environmental bacterium in Australia and West Africa. The primary risk factor associated with Buruli ulcer is proximity to slow moving water. Environmental constraints for disease are shown by the absence of infection in arid regions of infected countries. A particularly mysterious aspect of Buruli ulcer is the fact that endemic and non-endemic villages may be only a few kilometers apart within the same watershed. Recent studies suggest that aquatic invertebrate species may serve as reservoirs for M. ulcerans, although transmission pathways remain unknown. Systematic studies of the distribution of M. ulcerans in the environment using standard ecological methods have not been reported. Here we present results from the first study based on random sampling of endemic and non-endemic sites. In this study PCR-based methods, along with biofilm collections, have been used to map the presence of M. ulcerans within 26 aquatic sites in Ghana. Results suggest that M. ulcerans is present in both endemic and non-endemic sites and that variable number tandem repeat (VNTR profiling can be used to follow chains of transmission from the environment to humans. Our results suggesting that the distribution of M. ulcerans is far broader than the distribution of human disease is characteristic of environmental pathogens. These findings imply that focal demography, along with patterns of human water contact, may play a major role in transmission of Buruli ulcer.

  1. Features and distribution patterns of Chinese endemic seed plant species

    Ji-Hong HUANG; Jian-Hua CHEN; Jun-Sheng YING; Ke-Ping MA

    2011-01-01

    We compiled and identified a list of Chinese. endemic seed plant species based on a large number of published References and expert reviews. The characters of these seed plant species and their distribution patterns were described at length. China is rich in endemic seed plants, with a total of 14 939 species (accounting for 52.1%of its total seed plant species) belonging to 1584 genera and 191 families. Temperate families and genera have a significantly higher proportion of endemism than cosmopolitan and tropical ones. The most primitive and derived groups have significantly higher endemism than the other groups. The endemism of tree, shrub, and liana or vine is higher than that of total species; in contrast, the endemism of herb is lower than that of total species. Geographically,these Chinese endemic plants are mainly distributed in Yunnan and Sichuan provinces, southwest China. Species richness and proportion of these endemic plants decrease with increased latitude and have a unimodal response to altitude. The peak value of proportion of endemism is at higher altitudes than that of total species and endemic species richness. The proportions of endemic shrub, liana or vine, and herb increase with altitude and have a clear unimodal curve. In contrast, the proportion of tree increases with altitude, with a sudden increase at~4000 m and has a completely different model. To date, our study provides the most comprehensive list of Chinese endemic seed plant species and their basic composition and distribution features.

  2. Patterns of plant diversity and endemism in Namibia

    P. Craven

    2006-12-01

    Full Text Available Species richness, endemism and areas that are rich in both species and endemic species were assessed and mapped for Namibia. High species diversity corresponds with zones where species overlap. These are particularly obvious where there are altitudinal variations and in high-lying areas. The endemic flora of Namibia is rich and diverse. An estimated 16% of the total plant species in Namibia are endemic to the country. Endemics are in a wide variety of families and sixteen genera are endemic. Factors that increase the likelihood of endemism are mountains, hot deserts, diversity of substrates and microclimates. The distribution of plants endemic to Namibia was arranged in three different ways. Firstly, based on a grid count with the phytogeographic value o f the species being equal, overall endemism was mapped. Secondly, range restricted plant species were mapped individually and those with congruent distribution patterns were combined. Thirdly, localities that are important for very range-restricted species were identified. The resulting maps o f endemism and diversity were compared and found to correspond in many localities. When overall endemism is compared with overall diversity, rich localities may consist of endemic species with wide ranges. The other methods identify important localities with their own distinctive complement of species.

  3. Glycolytic potential and ultimate muscle pH values in red deer (Cervus elaphus and fallow deer (Dama dama

    Eva Wiklund

    2004-04-01

    Full Text Available The ultimate pH value of meat (measured at approx. 24 hours post slaughter gives information about the technological quality, i.e. shelf life, colour, water-holding properties and tenderness and is a direct consequence of muscle glycogen (energy levels at slaughter. It may therefore also indicate whether or not the animal has been exposed to stressful energy depleting events prior to slaughter. In the present study, 141 animals (130 red deer (Cervus elaphus and 11 fallow deer (Dama dama were included to investigate the relationship between ultimate pH and residual glycogen concentration in red deer and fallow deer M. longissimus. In addition, the muscle glycogen content and ultimate pH values in three red deer muscles (Mm. triceps brachii, longissimus and biceps femoris were studied. M. triceps brachii had higher ultimate pH and lower glycogen content compared with the other two studied muscles. The frequency of intermediate DFD (5.8≤ pH<6.2 was 5.4% in red deer M. longissimus, compared with 9.1% in fallow deer, while the frequency of DFD (pH≥ 6.2 was much lower in red deer (3.8% than in fallow deer (54.5%. A curvilinear relationship between ultimate pH and total glucose concentration (glycogen and glucose 30 min post slaughter in red deer and fallow deer M. longissimus was found. The relationship between muscle pH and lactic acid concentration however, was indicated to be linear. A significant variation in total glucose concentration at ultimate pH below 5.80 was observed, including values in the range from 18 to 123 mmol/kg wet tissue. It was concluded that further studies are needed to further explore the relationship between muscle glycogen content and technological and sensory quality attributes of meat from different deer species.Abstract in Swedish / Sammanfattning:Köttets pH-värde (mätt ca 24 timmar efter slakt har stor betydelse för den teknologiska kvaliteten som t. ex. hållbarhet, färg, vattenhållande förmåga och m

  4. Large-scale model-based assessment of deer-vehicle collision risk.

    Torsten Hothorn

    Full Text Available Ungulates, in particular the Central European roe deer Capreolus capreolus and the North American white-tailed deer Odocoileus virginianus, are economically and ecologically important. The two species are risk factors for deer-vehicle collisions and as browsers of palatable trees have implications for forest regeneration. However, no large-scale management systems for ungulates have been implemented, mainly because of the high efforts and costs associated with attempts to estimate population sizes of free-living ungulates living in a complex landscape. Attempts to directly estimate population sizes of deer are problematic owing to poor data quality and lack of spatial representation on larger scales. We used data on >74,000 deer-vehicle collisions observed in 2006 and 2009 in Bavaria, Germany, to model the local risk of deer-vehicle collisions and to investigate the relationship between deer-vehicle collisions and both environmental conditions and browsing intensities. An innovative modelling approach for the number of deer-vehicle collisions, which allows nonlinear environment-deer relationships and assessment of spatial heterogeneity, was the basis for estimating the local risk of collisions for specific road types on the scale of Bavarian municipalities. Based on this risk model, we propose a new "deer-vehicle collision index" for deer management. We show that the risk of deer-vehicle collisions is positively correlated to browsing intensity and to harvest numbers. Overall, our results demonstrate that the number of deer-vehicle collisions can be predicted with high precision on the scale of municipalities. In the densely populated and intensively used landscapes of Central Europe and North America, a model-based risk assessment for deer-vehicle collisions provides a cost-efficient instrument for deer management on the landscape scale. The measures derived from our model provide valuable information for planning road protection and defining

  5. Elk and deer studies related to the Basalt Waste Isolation Project

    A study of elk (Cervus elaphus) and deer (Odocoileus hemionus) was conducted in the vicinity of planned site characterization activities for the Basalt Waste Isolation Project (BWIP). Both species are known to be sensitive to disturbance and are considered important species because they are recreationally and/or commercially valuable. The principal objectives of the study were to (1) estimate pre-activity (site characterization) recruitment of deer and elk, (2) characterize deer and elk use of limited habitats critical to their survival (e.g., riparian areas), (3) describe preferential habitat use by deer and elk during critical seasons (i.e., winter and summer), and (4) document pre-activity distributions of seasonal home range centers of deer and elk. Early termination of BWIP prevented some of the objectives from being fully addressed. Fifteen adult elk (11 females and 4 males) and 19 female deer equipped with radio transmitters were studied on the Arid Lands Ecology (ALE) Reserve from February through December 1987. More than 1800 relocations of the marked elk and deer were made during aerial and ground tracking sessions. Deer confined their activities to within 2 km of water sources. In contrast, elk used 6-12 times the average area used by deer. As with deer, female elk were closely associated with available water sources during the summer and fall, presumably because of the physiological demands of lactation. However, during the winter, female elk showed no preference for areas near water, as did male elk throughout the study. Riparian areas, which are scarce on the arid Hanford Site, are particularly valuable habitat to both elk and deer because they provide drinking water and succulent forage during the dry summer and early fall months

  6. Environmental Factors Influencing White-Tailed Deer (Odocoileus virginianus Exposure to Livestock Pathogens in Wisconsin.

    Shelli Dubay

    Full Text Available White-tailed deer (Odocoileus virginianus are commonly exposed to disease agents that affect livestock but environmental factors that predispose deer to exposure are unknown for many pathogens. We trapped deer during winter months on two study areas (Northern Forest and Eastern Farmland in Wisconsin from 2010 to 2013. Deer were tested for exposure to six serovars of Leptospira interrogans (grippotyphosa, icterohaemorrhagiae, canicola, bratislava, pomona, and hardjo, bovine viral diarrhea virus (BVDV-1 and BVDV-2, infectious bovine rhinotracheitis virus (IBR, and parainfluenza 3 virus (PI3. We used logistic regression to model potential intrinsic (e.g., age, sex and extrinsic (e.g., land type, study site, year, exposure to multiple pathogens variables we considered biologically meaningful to exposure of deer to livestock pathogens. Deer sampled in 2010-2011 did not demonstrate exposure to BVDV, so we did not test for BVDV in subsequent years. Deer had evidence of exposure to PI3 (24.7%, IBR (7.9%, Leptospira interrogans serovar pomona (11.7%, L. i. bratislava (1.0%, L. i. grippotyphosa (2.5% and L. i. hardjo (0.3%. Deer did not demonstrate exposure to L. interrogans serovars canicola and icterohaemorrhagiae. For PI3, we found that capture site and year influenced exposure. Fawns (n = 119 were not exposed to L. i. pomona, but land type was an important predictor of exposure to L. i. pomona for older deer. Our results serve as baseline exposure levels of Wisconsin white-tailed deer to livestock pathogens, and helped to identify important factors that explain deer exposure to livestock pathogens.

  7. Chronic wasting disease in a Wisconsin white-tailed deer farm

    Keane, D.P.; Barr, D.J.; Bochsler, P.N.; Hall, S.M.; Gidlewski, T.; O'Rourke, K. I.; Spraker, T.R.; Samuel, M.D.

    2008-01-01

    In September 2002, chronic wasting disease (CWD), a prion disorder of captive and wild cervids, was diagnosed in a white-tailed deer (Odocoileus virginianus) from a captive farm in Wisconsin. The facility was subsequently quarantined, and in January 2006 the remaining 76 deer were depopulated. Sixty animals (79%) were found to be positive by immunohistochemical staining for the abnormal prion protein (PrPCWD) in at least one tissue; the prevalence of positive staining was high even in young deer. Although none of the deer displayed clinical signs suggestive of CWD at depopulation, 49 deer had considerable accumulation of the abnormal prion in the medulla at the level of the obex. Extraneural accumulation of the abnormal protein was observed in 59 deer, with accumulation in the retropharyngeal lymph node in 58 of 59 (98%), in the tonsil in 56 of 59 (95%), and in the rectal mucosal lymphoid tissue in 48 of 58 (83%). The retina was positive in 4 deer, all with marked accumulation of prion in the obex. One deer was considered positive for PrPCWD in the brain but not in the extraneural tissue, a novel observation in white-tailed deer. The infection rate in captive deer was 20-fold higher than in wild deer. Although weakly related to infection rates in extraneural tissues, prion genotype was strongly linked to progression of prion accumulation in the obex. Antemortem testing by biopsy of rectoanal mucosal-associated lymphoid tissue (or other peripheral lymphoid tissue) may be a useful adjunct to tonsil biopsy for surveillance in captive herds at risk for CWD infection.

  8. Sarcoptic mange in red deer from Spain: improved surveillance or disease emergence?

    Oleaga, A; Casais, R; González-Quirós, P; Prieto, M; Gortázar, C

    2008-06-14

    Concern about emerging diseases has risen in recent years, and multihost situations have become increasingly relevant for wildlife management and conservation. We present data on Asturias, northern Spain, where 80 mangy red deer (Cervus elaphus) have been found since the beginning of the epizootic in chamois (Rupicapra pyrenaica parva) in 1993. We combine field and necropsy data with the results of a serosurvey using an in-house ELISA test to evaluate if deer mange due to Sarcoptes scabiei is an emerging disease in this area. The mean number of deer mange cases per year was 5, with a maximum of 16. No significant relationship was detected between monthly temperatures, rainfall or number of days with snow cover and the annual number of sarcoptic mange cases in red deer. Only 4 mangy red deer (5%) were detected outside the limits of scabietic chamois distribution during the same year, and all were less than 2500 m away from that limit. The longest distance reported between two consecutive mangy deer locations was 18 km. Mange cases were significantly more frequent in stags than in hinds and in adults than in juvenile deer. The time of the first mange detection in chamois in each sector, year with minimum number of chamois recorded, year with maximum chamois population decline rate and chamois density offered no significant correlation with red deer mange cases appearance moment and frequency. In the mange affected area, ELISA testing of 327 blood samples from hunter-harvested deer without obvious mange-compatible lesions revealed only 4 seropositive animals. All 83 sera from hunting preserves without clinical cases yielded negative ELISA results. According to these epidemiological data mange does not seem to threaten red deer populations in Asturias. However, continued monitoring of deer health and ELISA testing for sarcoptic mange is advisable. PMID:18430519

  9. Mural folliculitis and alopecia caused by infection with goat-associated malignant catarrhal fever virus in two sika deer.

    Crawford, Timothy B; Li, Hong; Rosenburg, Stuart R; Norhausen, Robert W; Garner, Michael M

    2002-09-15

    Two sika deer from a zoo in Florida were examined because of chronic hair loss and skin lesions. No common causes of alopecia were identified in either deer. One deer was treated with prednisone, but the condition worsened when the dosage was decreased. Both deer were euthanatized after several months because of continued disease. The predominant histologic lesion in skin specimens was granulomatous mural folliculitis. Serologic testing and sequencing of fragments produced with a consensus polymerase chain reaction assay indicated that both deer were infected with caprine herpesvirus-2, a newly recognized member of the malignant catarrhal fever group of viruses. Disease in these deer was substantially different from that typically seen following infection with ovine herpesvirus-2, the sheep-associated malignant catarrhal fever virus. Findings in these deer establish the pathogenicity of caprine herpesvirus-2 in sika deer and illustrate the ability of this group of complex herpesviruses to cause a wide variety of clinical abnormalities in diverse species.

    2016-01-01

    White-tailed deer (Odocoileus virginianus) populations are impacting long-term regeneration across eastern United States forests. Deer distribution and resulting herbivory patterns are variable across a landscape due to habitat patchiness and topography. It is poorly understood how features associated with topography control deer herbivory. We examined the heterogeneity of deer herbivory as it affects sapling densities across a single forest-type landscape on the Cumberland Plateau. The 1242 ...

  18. Behavioral ecology of sika deer in spring in semi-natural area

    2001-01-01

    Behaviors of sika deer in spring were studied by scan sampling, ad libitum sampling, and all-occurrence recording methods during 1998. The results showed that behaviors of sika deer in spring can be classified by seven categories: grazing, ruminating, bedding, moving, standing, drinking, alert, agonistic and other behaviors. Various behavioral models were more regular. Grazing behavior was a kind of mainly behavioral model.

    2016-08-01

    Twenty-seven species of the genus Onchocerca (Nematoda; Filarioidea) can cause a vector-borne parasitic disease called onchocercosis. Most Onchocerca species infect wild and domestic ungulates or the dog, and one species causes river blindness in humans mainly in tropical Africa. The European red deer (Cervus e. elaphus) is host to four species, which are transmitted by blackflies (simuliids) or biting midges (ceratopogonids). Two species, Onchocerca flexuosa and Onchocerca jakutensis, produce subcutaneous nodules, whereas Onchocerca skrjabini and Onchocerca garmsi live free in the hypodermal serous membranes. During the hunting season, September 2013, red deer (n = 25), roe deer (Capreolus c. capreolus, n = 6) and chamois (Rupicapra r. rupicapra, n = 7), all shot in the Grisons Region (Switzerland) were investigated for the presence of subcutaneous nodules which were enzymatically digested, and the contained Onchocerca worms were identified to species by light and scanning electron microscopy as well as by PCR/sequencing. In addition, microfilariae from skin samples were collected and genetically characterized. Neither nodules nor microfilariae were discovered in the roe deer and chamois. Adult worms were found in 24% of red deer, and all of them were identified as O. jakutensis. Two morphologically different microfilariae were obtained from five red deer, and genetic analysis of a skin sample of one red deer indicated the presence of another Onchocerca species. This is the first report of O. jakutensis in Switzerland with a prevalence in red deer similar to that in neighbouring Germany. PMID:27617204

    We report the first description of Bartonella prevalence and genetic diversity in 64 Honshu sika deer (Cervus nippon centralis) and 18 Yezo sika deer (Cervus nippon yesoensis) in Japan. Overall, Bartonella bacteremia prevalence was 41.5% (34/82). The prevalence in wild deer parasitized with ticks and deer keds was 61.8% (34/55), whereas no isolates were detected in captive deer (0/27) free of ectoparasites. The isolates belonged to 11 genogroups based on a combination of the gltA and rpoB gene sequences. Phylogenetic analysis of concatenated sequences of the ftsZ, gltA, ribC, and rpoB genes of 11 representative isolates showed that Japanese sika deer harbor three Bartonella species, including B. capreoli and two novel Bartonella species. All Yezo deer's isolates were identical to B. capreoli B28980 strain isolated from an elk in the USA, based on the sequences of the ftsZ, gltA, and rpoB genes. In contrast, the isolates from Honshu deer showed a higher genetic diversity. PMID:22832020

  3. Alternative feeding strategies and potential disease transmission in Wisconsin white-tailed deer

    Thompson, A.K.; Samuel, M.D.; VanDeelen, T.R.

    2008-01-01

    We conducted experimental feeding using 3 feeding methods (pile, spread, trough) and 2 quantities (rationed, ad libitum) of shelled corn to compare deer activity and behavior with control sites and evaluate potential direct and indirect transmission of infectious disease in white-tailed deer (Odocoileus virginianus) in central Wisconsin, USA. Deer use was higher at 2 of the feeding sites than at natural feeding areas (P ??? 0.02). Deer spent a higher proportion of time (P < 0.01) feeding at pile (49%) and spread (61%) treatments than at natural feeding areas (36%). We found higher deer use for rationed than ad libitum feeding quantities and feeding intensity was greatest at rationed piles and lowest at ad libitum spreads. We also observed closer pairwise distances (???0.3 m) among deer when corn was provided in a trough relative to spread (P=0.03). Supplemental feeding poses risks for both direct and indirect disease transmission due to higher deer concentration and more intensive use relative to control areas. Concentrated feeding and contact among deer at feeding sites can also increase risk for disease transmission. Our results indicated that restrictions on feeding quantity would not mitigate the potential for disease transmission None of the feeding strategies we evaluated substantially reduced the potential risk for disease transmission and banning supplemental feeding to reduce transmission is warranted.

    2015-02-01

    The deer ked (Lipoptena cervi) is a haematophagous ectoparasite of cervids that harbours haemotrophic Bartonella. A prerequisite for the vector competence of the deer ked is the vertical transmission of the pathogen from the mother to its progeny and transstadial transmission from pupa to winged adult. We screened 1154 pupae and 59 pools of winged adult deer keds from different areas in Finland for Bartonella DNA using PCR. Altogether 13 pupa samples and one winged adult deer ked were positive for the presence of Bartonella DNA. The amplified sequences were closely related to either B. schoenbuchensis or B. bovis. The same lineages were identified in eight blood samples collected from free-ranging moose. This is the first demonstration of Bartonella spp. DNA in a winged adult deer ked and, thus, evidence for potential transstadial transmission of Bartonella spp. in the species. PMID:24901607

    Full Text Available The Himalayan musk deer (Moschus chrysogaster is an endangered species found in the Himalayan region of Nepal. This research was conducted in the Manaslu Conservation Area to explore the deers general population status, distribution, habitat preference and conservation threats. Musk deer are distributed within the altitudinal range of 3128-4039 m spanning 35.43 km2, with the most potential habitat in the Prok VDC (Village Development Committee. Within this area the Musk deer highly preferred altitudes between 3601-3800 m, with a 21-30 slope, 26-50% crown cover and 26-50% ground cover. There are significant differences in the use of different habitat types in terms of altitude, slope, crown cover, ground cover and topography. The preferred tree species were Abies spectabilis, Betula utilis and Rhododendron species. Poaching of deer for their musk is the major conservation threat.

  7. Mule deer antlers as biomonitors of strontium-90 on the Hanford Site

    This study evaluated deer antlers as indicators of animal uptake of localized 90Sr contamination on the Hanford Site in south-central Washington. Levels of 90Sr were examined in 38 mule deer (Odocoileus hemionus hemionus) antler samples collected near and distant from previously active nuclear reactor facilities and from a reference site in central Oregon. Results showed that 90Sr concentrations in antlers collected near reactor facilities were significantly higher (P90Sr compared with Hanford. Strontium-90 concentrations in deer antlers collected at the reference locations were higher than Hanford site deer, presumably because the deer inhabited mountain regions during the summer months that received more atmospheric fallout from historic weapons testing

  8. Deer hunting on Pennsylvania's public and private lands: A two-tiered system of hunters?

    Stedman, R.C.; Bhandari, P.; Luloff, A.E.; Diefenbach, D.R.; Finley, J.C.

    2008-01-01

    Recreational hunting is crucial for controlling white-tailed deer populations. Public land is increasingly important as access to private lands declines. However, differences between public and private land hunters remain unknown. Our study of Pennsylvania hunters revealed differences between private and public land hunters that may pose problems for management. Hunters who only hunted public land had lower harvest rates, especially of antlerless deer, spent less time hunting, were less committed to hunting, were more likely to hunt alone, less likely to belong to a hunting camp, and more likely to live in urban areas. They were less likely to believe that high deer populations could damage forest ecosystems, and less willing to harvest antlerless deer. The implications of these findings, in the context of already-declining hunter capacity to keep deer populations in check, and concomitant declining access to private land, are discussed.

  9. Action Central: Red Deer steps forward as oilfield operations capital

    The growth of Red Deer as the center of the oil and natural gas service industry in the Alberta oilpatch was discussed. Red Deer is the home base of many of Alberta's major service companies (Haliburton, Schlumberger, Computalog, Nowsco, Canadian Fracmaster, Hughes, Bonus and Challenger), and new companies are regularly looking for industrial properties to establish themselves in the city. Industrial land acquisition currently runs at about triple of the average for the previous ten years. Another significant spin-off of energy wealth around Red Deer comes from the manufacturing of petrochemical building blocks of plastics, at nearby Joffre. With expansion projects that include Union Carbide Canada and Amoco Canada, predictions of population growth to 100,000 from the current 75,000, are commonplace. These expansion projects spell up to 2,500 construction jobs for the next three years, and then 400 new permanent plant positions that will pay $60,000 and up for skilled specialist jobs. There are some concerns about the threat of the Alliance Gas Pipeline project that if it materializes it might export many jobs, along with the natural gas, to the United States. However, these concerns are less serious than the fear that Alliance threatens to raise the price of the raw material by draining away surpluses from the industry, thus removing the major Canadian advantage in competition with U.S. industry. Alliance supporters counter that even at maximum export through the Cochin liquid pipeline, only half of the ethane production that will be potentially available, will be exported

    The performance characteristics of a newly developed liquid chromatography-mass spectrometry (LC-MS) method were validated and demonstrated to be fit for purpose in a pharmacokinetic and tissue depletion study of white-tailed deer and bison. Tulathromycin was extracted from bison and deer sera with acetonitrile or trifluoroacetic acid and K2 HPO4 (pH 6.8) buffer solution and cleaned up on a conditioned Bond-Elut cartridge. Tulathromycin, retained on the cartridge; it was eluted with methanol containing 2% formic acid, dried, re-constituted in methanol/1% formic acid, and analyzed by LC-MS. The limit of quantification (LOQ) of the method was 0.6 ng/mL in serum and 0.6 ng/g in tissue with RSDs ≤ 10% and accurate over the linear calibration range of 0.8-100 ng/mL for bison serum, 0.6-50 ng/mL for deer serum, 100-2500 ng/g for deer muscle tissue, and 500-5000 ng/g for deer lung tissue, all with coefficients of determination, r(2) ≥0.99. The validated method was used to quantify the concentration of tulathromycin residues in serum of bison and deer and selected tissue (lung and muscle tissue) samples obtained from 10 healthy, white-tailed deer that were administered the therapeutic dose approved for cattle (i.e., a single 2.5 mg/kg subcutaneous injection of tulathromycin in the neck). The deer were included in a tulathromycin drug depletion study. © 2016 Her Majesty the Queen in Right of Canada. Drug Testing and Analysis © 2016 John Wiley & Sons, Ltd. PMID:27443215

    Chronic wasting disease (CWD) is an efficiently transmitted prion disease of cervids, now identified in 22 United States, 2 Canadian provinces and Korea. One hallmark of CWD is the shedding of infectious prions in saliva, as demonstrated by bioassay in deer. It is also clear that the concentration of prions in saliva, blood, urine and feces is much lower than in the nervous system or lymphoid tissues. Rapid in vitro detection of CWD (and other) prions in body fluids and excreta has been probl...

    2014-09-01

    Irreversible shifts in ecosystems caused by large herbivores are becoming widespread around the world. We analyzed data derived from the 2009-2010 Sika Deer Impact Survey, which assessed the geographical distribution of deer impacts on vegetation through a questionnaire, on a scale of 5-km grid-cells. Our aim was to identify areas facing irreversible ecosystem shifts caused by deer overpopulation and in need of management prioritization. Our results demonstrated that the areas with heavy impacts on vegetation were widely distributed across Japan from north to south and from the coastal to the alpine areas. Grid-cells with heavy impacts are especially expanding in the southwestern part of the Pacific side of Japan. The intensity of deer impacts was explained by four factors: (1) the number of 5-km grid-cells with sika deer in neighboring 5 km-grid-cells in 1978 and 2003, (2) the year sika deer were first recorded in a grid-cell, (3) the number of months in which maximum snow depth exceeded 50 cm, and (4) the proportion of urban areas in a particular grid-cell. Based on our model, areas with long-persistent deer populations, short snow periods, and fewer urban areas were predicted to be the most vulnerable to deer impact. Although many areas matching these criteria already have heavy deer impact, there are some areas that remain only slightly impacted. These areas may need to be designated as having high management priority because of the possibility of a rapid intensification of deer impact.

  15. DIAGNOSIS AND THERAPY OF LIVER FLUKE (FASCIOLOIDES MAGNA) INFECTION IN FALLOW DEER (DAMA DAMA) IN SERBIA.

    Trailović, Saša M; Marinković, Darko; Kulišić, Zoran

    2016-04-28

    Giant liver fluke ( Fascioloides magna ) infection is an important health problem of cervids in southeastern Europe. We measured the prevalence and intensity of infection with F. magna in a fenced area near the Danube River in the South Bačka District of Serbia. Parasitologic, pathomorphologic, and histopathologic examinations were conducted from November 2007 to February 2008, beginning with a population of 127 adult fallow deer ( Dama dama ). After a positive diagnosis, therapy with triclabendazole-medicated corn was applied. Deer were treated at four baiting stations, using medicated feed providing triclabendazole at an estimated dose of 10-14 mg/kg of body weight per deer. Treatment lasted for 7 d in early February 2008 and an additional 7 d 2 wk later. For the complete success of pharmacotherapy it was necessary to prevent any contact of deer with the snail intermediate host ( Galba truncatula ). Intervention in the habitat, removing grass and low vegetation, and draining ponds reduces the possibility of contact. Six months after the treatment, livers of hunted deer were reddish, with fibrous tracks; pigmentation and cysts in the parenchyma were surrounded by a fibrous capsule and their fecal samples contained no eggs of F. magna . Over the following years, livers of hunted deer were negative, and the last control cull in March 2015 confirmed complete absence of infection. We reconfirmed the presence of giant liver flukes in fallow deer in Serbia, apparently the result of natural spread across the Danube from Hungary and Croatia. We also report that the treatment of deer with triclabendazole-medicated corn is an effective method for administration of therapeutic doses of drug in semicaptive deer. Interventions in the environment are necessary to prevent recontact of deer with habitats used by the snail intermediate host, and enable the success of the therapy. PMID:26967130

  16. Radiocesium transfer to roe deer and moose. Modelling and experimental studies

    This thesis summarises and discusses results of modelling and experimental studies of radiocesium transfer to roe deer and moose. Experimental studies were conducted in two forested areas highly contaminated by the Chernobyl deposition. One area is 40 km north west of Uppsala, in central Sweden and the other is in the Bryansk region of Russia. Experimental studies in Sweden are based on measurements of radiocesium levels in roe deer and moose carried out during 1988-1997. Issues addressed were: reasons for seasonal variations of radiocesium levels in roe deer, between years variations and long-term dynamics, correlation between radiocesium levels in roe deer and moose and role of fungi for radiocesium transfer to roe deer and moose. Experimental studies in Bryansk focused on calibration and validation of models developed during the study. Radiocaesium levels in roe deer increase in up to 5 times in summer and autumn due to mushrooms ingestion and remain almost constant the rest of the year. Mushrooms ingestion explained quantitatively between years variations in radiocesium levels in roe deer and 70 % of the variations in moose. The 137Cs levels of in roe deer and moose will decrease at a rate close to 137Cs physical half-life. The radiocesium levels were 2-2.5 times higher in roe deer than in moose. A conceptual model of radiocesium migration and transfer in a forest ecosystem is presented as an interaction matrix. This matrix can be used to study migration pathways and cause-effect relationships and to present status of knowledge. A model of radiocesium transfer in forest ecosystems was developed, which simulates well seasonal and long-term dynamics of radiocesium levels in roe deer and moose. A process level model of radiocesium transfer from soil to understorey plants is used to derive equations relating soil-to-plant concentration ratios with soil characteristics

  17. Linking Hunter Knowledge with Forest Change to Understand Changing Deer Harvest Opportunities in Intensively Logged Landscapes

    Gary Kofinas

    2009-06-01

    Full Text Available The effects of landscape changes caused by intensive logging on the availability of wild game are important when the harvest of wild game is a critical cultural practice, food source, and recreational activity. We assessed the influence of extensive industrial logging on the availability of wild game by drawing on local knowledge and ecological science to evaluate the relationship between forest change and opportunities to harvest Sitka black-tailed deer (Odocoileus hemionus sitkensis on Prince of Wales Island, Alaska. We used data collected through interviews with local deer hunters and GIS analysis of land cover to determine relationships among landscape change, hunter access, and habitat for deer hunting over the last 50 yr. We then used these relationships to predict how harvest opportunities may change in the future. Intensive logging from 1950 into the 1990s provided better access to deer and habitat that facilitated deer hunting. However, successional changes in intensively logged forests in combination with a decline in current logging activity have reduced access to deer and increased undesirable habitat for deer hunting. In this new landscape, harvest opportunities in previously logged landscapes have declined, and hunters identify second-growth forest as one of the least popular habitats for hunting. Given the current state of the logging industry in Alaska, it is unlikely that the logging of the remaining old-growth forests or intensive management of second-growth forests will cause hunter opportunities to rebound to historic levels. Instead, hunter opportunities may continue to decline for at least another human generation, even if the long-term impacts of logging activity and deer harvest on deer numbers are minimal. Adapting hunting strategies to focus on naturally open habitats such as alpine and muskeg that are less influenced by external market forces may require considerably more hunting effort but provide the best option for

  18. Toponyms for centers of endemism in Madagascar

    2012-06-01

    Full Text Available A biogeographical model was proposed in 2006 to explain the centers of endemism and the importance of riparian for­est of some watersheds as refuges or dispersal corridors during paleoclimatic oscillations. Here, we consider these geographical features highlighting their biological and socio-cultural importance. We explain the etymology or eponymy of the major rivers of the retreat-dispersal watersheds, i.e., the drainage basins of Bemarivo, Antainambalana, Mangoro, Manampatrana, Mananara South, Mandrare, Onilahy, Mangoky, Tsiribihina, Betsiboka, Maevarano, Sambirano, and Mahavavy North. We propose a toponymy for each of the 15 centers of endemism and highlight their peculiarities. We named the cent­ers of endemism of Vohimarina, Masoala, Analanjirofo, Tanala, Manombo, Anosy, Ranopiso, Karimbola, Mikea, Menabe, Melaky, Sofia, Ampasindava, Ankify, and Ankarana. We illustrate each center of endemism with a flagship spe­cies and report on its natural and cultural histories, and conservation. RÉSUMÉUn modèle biogéographique a été proposé en 2006 pour expliquer les centres d’endémisme de la biodiversité et l’importance des ripisylves de certains bassins versants en tant que refuges ou couloirs de dispersion au cours des oscillations paléoclimatiques. Ici, nous considérons ces dispositifs géographiques en soulignant leur importance biologique et socioculturelle.

  19. Benzimidazole resistance in Haemonchus contortus recovered from farmed red deer.

    Nagy, Gábor; Csivincsik, Ágnes; Zsolnai, Attila; Sugár, László

    2016-09-01

    Thirty Haemonchus contortus male worms were collected from farmed red deer yearlings in order to determine whether routine administration of albendazole for a long-term period (17 years) could select anthelmintic resistance. PCR-RFLP method based on single-nucleotide polymorphism of codon 200 in isotype 1 ß-tubulin gene (Phe200Tyr) was applied. The results showed a significant frequency of either the resistant allele (85 %) or the homozygous resistant genotype (70 %). By chi-square test, Hardy-Weinberg equilibrium of the population was accepted (p = 0.334, power of test 0.01). True prevalence of the resistant genotype (RR) was estimated to be 46.5-87.2 % (confidence interval 95 %) calculated by Sterne's exact method. These results confirmed that long-term use of benzimidazoles could change the relative allele frequency of genes associated with drug resistance and may cause a large-scale spread of the resistant allele. To our knowledge, this study supported benzimidazole resistance in Haemonchus contortus in red deer for the first time. PMID:27249966

  20. Experimental trichinellosis in fallow-deer (Dama dama L.

    Moretti A.

    2001-06-01

    Full Text Available Herbivora can play a very important role in spreading trichinellosis, as showed by the massive epidemics in man, caused by the consumption of horse meat in the last years. In this context, the present study has been undertaken to verify, through an experimental infection, the susceptibility, together with other biological parameters, of fallow-deer to Trichinella infection. The four animals, 8-9 months of age and 18-25 Kg body weight, were orally infected with low doses of Trichinella britovi and T. pseudospiralis (2,000 larvae/animal. After day 30 p.i,, the animals were necropsied and, using artificial digestion methods, larval burden of Trichinella in muscle tissues was determined. Histopathological, serological (lgG monoclonal blocking ELISA and biochemical data were assessed during the experiment. The results showed the susceptibility of fallow-deer to T. britovi and T. pseudospiralis infection; under the same inoculum size, the number of larvae/g was higher in group infected with T. britovi. The animals showed a higher immunological response to T. pseudospiralis infection. The results are discussed.

  1. Evolutionary relationships of endemic/epidemic and sylvatic dengue viruses.

    Wang, E; Ni, H; Xu, R; Barrett, A D; Watowich, S J; Gubler, D J; Weaver, S C

    2000-04-01

    Endemic/epidemic dengue viruses (DEN) that are transmitted among humans by the mosquito vectors Aedes aegypti and Aedes albopictus are hypothesized to have evolved from sylvatic DEN strains that are transmitted among nonhuman primates in West Africa and Malaysia by other Aedes mosquitoes. We tested this hypothesis with phylogenetic studies using envelope protein gene sequences of both endemic/epidemic and sylvatic strains. The basal position of sylvatic lineages of DEN-1, -2, and -4 suggested that the endemic/epidemic lineages of these three DEN serotypes evolved independently from sylvatic progenitors. Time estimates for evolution of the endemic/epidemic forms ranged from 100 to 1,500 years ago, and the evolution of endemic/epidemic forms represents relatively recent events in the history of DEN evolution. Analysis of envelope protein amino acid changes predicted to have accompanied endemic/epidemic emergence suggested a role for domain III in adaptation to new mosquito and/or human hosts.

    Hepatitis E virus (HEV), a single stranded RNA, nonenveloped virus, belongs to the genus Hepevirus, in the family of Hepeviridae. In this study, 46 (5.43%) out of the 847 serum samples from sika deer (Cervus nippon) were detected as seropositive with hepatitis E virus (HEV) by enzyme linked immunosorbent assay (ELISA). These samples were collected from Inner Mongolia and Jilin and Heilongjiang provinces in China, between October 2012 and October 2013. Seroprevalence of HEV infection in male and female deer was 4.82% and 6.52%, respectively. HEV seroprevalence in sika deer from different geographical locations varied from 3.13% to 6.73%. There was no significant difference in HEV seroprevalence between sika deer collected in autumn (5.65%) and winter (4.85%). This is the first report of HEV seroprevalence in sika deer in China, which will provide foundation information for estimating the effectiveness of future measures to control HEV infection in sika deer in China and assessing the potential risk of humans infected with HEV after consumption of undercooked or raw meat from infected sika deer.

  4. Seasonal habitat selection of the red deer (Cervus elaphus alxaicus in the Helan Mountains, China

    Mingming Zhang

    2013-02-01

    Full Text Available We studied the seasonal habitat selection of the red deer, Cervus elaphus alxaicus Bobrinskii & Flerov, 1935, in the Helan Mountains, China, from December 2007 to December 2008. Habitat selection varied widely by season. Seasonal movements between high and low elevations were attributed to changes in forage availability, alpine topography, the arid climate of the Helan Mountains, and potential competition with blue sheep, Pseudois nayaur (Hodgson, 1833. The use of vegetation types varied seasonally according to food availability and ambient temperature. Red deer used montane coniferous forest and alpine shrub and meadow zones distributed above 2,000 m and 3,000 m in summer, alpine shrub and meadows above 3,000 m in autumn, being restricted to lower elevation habitats in spring and winter. The winter habitat of C. elaphus alxaicus was dominated by Ulmus glaucescens Franch. and Juglans regia Linnaeus, deciduous trees, and differed from the habitats selected by other subspecies of red deer. Cervus elaphus alxaicus preferred habitats with abundant vegetation coverage to open habitats in winter, but the reverse pattern was observed in summer and autumn. Red deer preferred gentle slopes (<10° but the use of slope gradient categories varied seasonally. Red deer avoidance of human disturbance in the Helan Mountains varied significantly by season. Information on red deer habitat selection can help understand the factors affecting seasonal movements and also support decision making in the management and conservation of red deer and their habitats.

    Paratuberculosis or Johne's disease (JD), caused by Mycobacterium avium subspecies paratuberculosis (MAP), is a chronic infectious granulomatous enteritis of ruminants and other animals, which has a worldwide occurrence, but little is known of MAP infection in domestic sika deer in Jilin Province, China. The objective of the present investigation was to examine seroprevalence and risk factors of MAP infection in Jilin Province. Serum samples collected from 1400 sika deer from 16 sika deer herds were collected in the 4 districts of the province between May 2013 and August 2014 and were tested independently for the presence of antibodies against MAP. A total of 247 (17.64 %) sika deer tested positive for MAP antibodies using a commercially available enzyme immunoassay kit. The management level of farm and collecting region of sika deer was the main risk factor associated with MAP infection. The present study revealed the seroprevalence of MAP infection in sika deer in Jilin Province, China, which provided the baseline data for taking comprehensive countermeasures and measures in effectively preventing and controlling MAP infection in sika deer.

  6. Iberian red deer: paraphyletic nature at mtDNA but nuclear markers support its genetic identity.

    Carranza, Juan; Salinas, María; de Andrés, Damián; Pérez-González, Javier

    2016-02-01

    Red deer populations in the Iberian glacial refugium were the main source for postglacial recolonization and subspecific radiation in north-western Europe. However, the phylogenetic history of Iberian red deer (Cervus elaphus hispanicus) and its relationships with northern European populations remain uncertain. Here, we study DNA sequences at the mitochondrial control region along with STR markers for over 680 specimens from all the main red deer populations in Spain and other west European areas. Our results from mitochondrial and genomic DNA show contrasting patterns, likely related to the nature of these types of DNA markers and their specific processes of change over time. The results, taken together, bring support to two distinct, cryptic maternal lineages for Iberian red deer that predated the last glacial maximum and that have maintained geographically well differentiated until present. Haplotype relationships show that only one of them contributed to the northern postglacial recolonization. However, allele frequencies of nuclear markers evidenced one main differentiation between Iberian and northern European subspecies although also supported the structure of both matrilines within Iberia. Thus, our findings reveal a paraphyletic nature for Iberian red deer but also its genetic identity and differentiation with respect to northern subspecies. Finally, we suggest that maintaining the singularity of Iberian red deer requires preventing not only restocking practices with red deer specimens belonging to other European populations but also translocations between both Iberian lineages.

    Full Text Available

    Malaria infection is still to be considered a major public health problem in those 106 countries where the risk of contracting the infection with one or more of the Plasmodium species exists. According to estimates from the World Health Organization, over 200 million cases and about 655.000 deaths have occurred in 2010. Estimating the real health and social burden of the disease is a difficult task, because many of the malaria endemic countries have limited diagnostic resources, especially in rural settings where conditions with similar clinical picture may coexist in the same geographical areas. Moreover, asymptomatic parasitaemia may occur in high transmission areas after childhood, when anti-malaria semi-immunity occurs. Malaria endemicity and control activities are very complex issues, that are influenced by factors related to the host, to the parasite, to the vector, to the environment and to the health system capacity to fully implement available anti-malaria weapons such as rapid diagnostic tests, artemisinin-based combination treatment, impregnated bed-nets and insecticide residual spraying while waiting for an effective vaccine to be made available.

    Full Text Available We present an annotated list for all land, aquatic and marine mammals known to occur in Peru and their distribution by ecoregions. We also present species conservation status according to international organizations and the legal conservation status in Peru. At present, we record 508 species, in 13 orders, 50 families, and 218 genera, making Peru the third most diverse country with regards to mammals in the New World, after Brazil and Mexico, and the fifth most diverse country for mammals in the World. This diversity includes 40 didelphimorphs, 2 paucituberculates, 1 manatee, 6 cingulates, 7 pilosa, 39 primates, 162 rodents, 1 rabbit, 2 soricomorphs, 165 bats, 34 carnivores, 2 perissodactyls, and 47 cetartiodactyls. Bats and rodents (327 species represent almost two thirds of total diversity (64% for Peru. Five genera and 65 species (12.8% are endemics to Peru, with the majority of these being rodents (45 species, 69,2%. Most of the endemic species are restricted to the Yungas of the eastern slope of the Andes (39 species, 60% followed by Selva Baja (14 species, 21.5%. The taxonomic status of some species is commented on, when those depart from accepted taxonomy. The marsupial Marmosa phaea; the rodents Melanomys caliginosus, M. robustulus, and Echinoprocta rufescens; the shrew Cryptotis equatoris; the bats Anoura fistulata, Phyllostomus latifolius, Artibeus ravus, Cynomops greenhalli, Eumops maurus, and Rhogeessa velilla; and the carnivore Nasuella olivacea are first records of species occurrence in Peru. Finally, we also include a list of 15 non-native species.

  9. Solar Radiation Determines Site Occupancy of Coexisting Tropical and Temperate Deer Species Introduced to New Zealand Forests.

    Full Text Available Assemblages of introduced taxa provide an opportunity to understand how abiotic and biotic factors shape habitat use by coexisting species. We tested hypotheses about habitat selection by two deer species recently introduced to New Zealand's temperate rainforests. We hypothesised that, due to different thermoregulatory abilities, rusa deer (Cervus timorensis; a tropical species would prefer warmer locations in winter than red deer (Cervus elaphus scoticus; a temperate species. Since adult male rusa deer are aggressive in winter (the rut, we also hypothesised that rusa deer and red deer would not use the same winter locations. Finally, we hypothesised that in summer both species would prefer locations with fertile soils that supported more plant species preferred as food. We used a 250 × 250 m grid of 25 remote cameras to collect images in a 100-ha montane study area over two winters and summers. Plant composition, solar radiation, and soil fertility were also determined for each camera location. Multiseason occupancy models revealed that direct solar radiation was the best predictor of occupancy and detection probabilities for rusa deer in winter. Multistate, multiseason occupancy models provided strong evidence that the detection probability of adult male rusa deer was greater in winter and when other rusa deer were present at a location. Red deer mostly vacated the study area in winter. For the one season that had sufficient camera images of both species (summer 2011 to allow two-species occupancy models to be fitted, the detection probability of rusa deer also increased with solar radiation. Detection probability also varied with plant composition for both deer species. We conclude that habitat use by coexisting tropical and temperate deer species in New Zealand likely depends on the interplay between the thermoregulatory and behavioural traits of the deer and the abiotic and biotic features of the habitat.

    Backgroud Studies on new vertebral internal fixations of animals are very important prior to clinical application. This study aimed to determine the feasibility of vertebral internal fixation on morphologic and biomechanical properties using deer and sheep as animal models and comparing to human data.Methods Thirty sets of fresh Sika deer lumbar, 30 sets of fresh sheep lumbar, and 20 sets of fresh lumbar from male cadavers were used. We examined the morphology of the centra and pedicles of the three groups, and determined the cancellous bone density and biomechanical properties in all groups.Results There were marked differences in all parameters measured between the different species. The sizes of the upper, middle, and lower transverse diameter were largest in the human, followed by the deer, then the sheep. The index of centrum transverse diameters and sagittal diameters were less than 0.8 (a triangle), and the deer was more similar to the human. The heights of the right vertebral pedicles and the anterior disc heights (IDH) were largest in the human, followed by the deer, then the sheep. The apparent density, elastic modulus, and ultimate load were largest in the sheep, followed by the deer, then the human. The range of motion (ROM) of functional lumbar units (FLUs) with a combined flexion-extension moment was largest in the human, followed by the deer then the sheep. Conclusions The deer lumbar is more similar to that of human in anatomical form and biomechanics than the sheep lumbar. As such, deer is more appropriate as an animal model for use in vertebral internal fixation studies.

    2016-06-01

    During the 2008-2011 time period, undiagnosed lesions were observed in 21 of 150 white-tailed deer fawns (Odocoileus virginianus) that were part of a captive deer herd at Mississippi State University. Clinical findings in healthy and diseased fawns from 0 to 90 days of age included bite and scratch marks followed by moderate to severe ear and tail necrosis. Gross necropsy findings of necrotizing ulcerative dermatitis correlated with histopathologic findings that included focally severe multifocal vasculitis, vascular necrosis, and thrombosis. This article is a clinical description of these previously unreported lesions associated with tissue necrosis in young captive white-tailed deer. PMID:27468041

  14. Parelaphostrongylus tenuis-associated meningoencephalitis in a sika deer (Cervus nippon).

    Gerhold, Richard W; Keel, M Kevin; Arnold, Kim; Hotton, Doug; Beckstead, Robert B

    2010-01-01

    An adult, female, free-ranging, sika deer (Cervus nippon yakushimae) from Wicomico County, Maryland, USA, was found circling and having no fear of humans. The animal was euthanized and submitted for a postmortem exam. There were no gross lesions and the deer was negative for rabies. Microscopic examination revealed lymphoplasmacytic, neutrophilic, and eosinophilic meningoencephalitis with intralesional adult nematodes, larvae, and eggs consistent with nematodes in the family Protostrongylidae. Parelaphostrongylus tenuis was identified by polymerase chain reaction and DNA sequencing. To our knowledge, this is the first report of P. tenuis-associated encephalitis in a sika deer.

    2005-03-01

    Surveillance of chronic wasting disease (CWD) was conducted by performing Western blot analysis of tissue samples from 136 sika deer (Cervus nippon) killed by hunters in the Tokachi district of Hokkaido Island. No prion protein (PrPSc) associated with CWD was detected in any of the samples. To assess amino acid polymorphisms of the sika deer PrP gene, nucleotide sequencing of the PrP gene was performed. The only amino acid polymorphisms detected were 3 silent mutations at nucleotide positions 63, 225 and 408. These results suggest that sika deer in the Tokachi district are genetically homogeneous, and are not infected with CWD. PMID:15805745

    Full Text Available The macroscopic anatomy of the stomach of the adult pampas deer, Ozotoceros bezoarticus (Linnaeus, 1758, a cervid species considered to ingest high quantities of grass in its natural diet, was described. Fourteen deceased adult pampas deer of both sexes from a captive breeding station were used for this study. There were no differences in the absolute or relative size from the different compartments of the stomach in relation to gender. Compared to measurements in other ruminants, pampas deer appeared anatomically capable of feeding on a variety of diets as an 'intermediate feeder'.

    The objectives of this study were to determine the prevalence of antibodies against brucellosis, leptospirosis, infectious bovine rhinotracheitis virus, and bovine viral diarrhea virus (BVDV) in white-tailed deer (Odocoileus virginianus) in northeastern Mexico. Deer (n=521) were captured from helicopter using a netgun on 15 ranches covering 62,114 ha in the states of Coahuila, Nuevo Leon, and Tamaulipas during spring 2004. The prevalence of antibodies against Leptospira, infectious bovine rhinotracheitis, BVDV, and brucellosis were 5.6, 41.1, 63.5, and 0%, respectively, indicating that white-tailed deer and cattle may share disease agents when cohabiting in northeastern Mexico.

The data suggests that short term, controlled dog hunting has little long-term effect on adult, female white-tailed deer movement on the Savannah River Site.

  19. Origin and differentiation of endemism in the flora of China

    2007-01-01

    The present paper analyzed 239 endemic genera in 67 families in the flora of seed plants in China.The results showed that there are five families containing more than ten endemic genera,namely,Gesneriaceae (27),which hereafter refers to the number of endemic genera in China,Composite (20),Labiatae (12),Cruciferae (11),and Umbelliferae (10),15 families with two endemic genera,and another 30 families with only one endemic genus.Four monotypic families (Ginkgoaceae,Davidiaceae,Eucommiaceae and Acanthochlamydaceae)are the most ancient,relict and characteristic in the flora of seed plants in China.Based on integrative data of systematics,fossil history,and morphological and molecular evidence of these genera,their origin,evolution and relationships were discussed.In gymnosperms,all endemic genera are relicts of the Arctic-Tertiary flora,having earlier evolutionary history,and can be traced back to the Cretaceous or to the Jurassic and even earlier.In angiosperms,the endemic genera are mostly relicts,and are represented in all lineages in the"Eight-Class System ofClassification of Angiosperms",and endemism can be found in almost every evolutionary stage of extant angiosperms.The relict genera once occupied huge areas in the northern hemisphere in the Tertiary or the late Cretaceous,while neo-endemism mostly originated in the late Tertiary.They came from Arctic-Tertiary,Paleo-tropical-Tertiary and Tethys-Tertiary florisitic elements,and the blend of the three elements with many genera of autochthonous origin.The endemism was formed when some dispersal routes such as the North Atlantic Land Bridge,and the Bering Bridge became discontinuous during the Tertiary,as well as the climate change and glaciations in the late Tertiary and the Quaternary.Therefore,the late Tertiary is the starting point of extant endemism of the flora in China.

  1. Energy metabolism and hematology of white-tailed deer fawns

    Rawson, R.E.; DelGiudice, G.D.; Dziuk, H.E.; Mech, L.D.

    1992-01-01

    Resting metabolic rates, weight gains and hematologic profiles of six newborn, captive white-tailed deer (Odocoileus virginianus) fawns (four females, two males) were determined during the first 3 mo of life. Estimated mean daily weight gain of fawns was 0.2 kg. The regression equation for metabolic rate was: Metabolic rate (kcal/kg0.75/day) = 56.1 +/- 1.3 (age in days), r = 0.65, P less than 0.001). Regression equations were also used to relate age to red blood cell count (RBC), hemoglobin concentration (Hb), packed cell volume, white blood cell count, mean corpuscular volume, mean corpuscular hemoglobin concentration (MCHC), and mean corpuscular hemoglobin. The age relationships of Hb, MCHC, and smaller RBC's were indicative of an increasing and more efficient oxygen-carrying and exchange capacity to fulfill the increasing metabolic demands for oxygen associated with increasing body size.

  2. a Uav-Based ROE Deer Fawn Detection System

    Israel, M.

    2011-09-01

    This paper presents a UAV based remote sensing system for the detection of fawns in the meadows. There is a high demand because during pasture mowing many wild animals, especially roe deer fawns are killed by mowing machines. The system was tested in several real situations especially with differing weather and iluminating conditions. Its primary sensor is a lightweight thermal infrared camera. The images are captured onboard of the flight system and also transmitted as analog video stream to the ground station, where the user can follow the camera live stream on a monitor for manual animal detection. Beside a high detection rate a fast workflow is another very important objective for this application. Therefore a waypoint planning software was developed that accelerates the workflow. At adequate illuminating and weather conditions the presented UAV-based fawn detection via thermal imaging is a comfortable, fast and reliable method.

  3. Maternal investment and reproductive success in Chinese water deer

    Christiane MAUGET; Robert MAUGET

    2009-01-01

    Among cervids, maternal investment, estimated as the amount of resources and care allocated to the offspring, was expected to be related to species body size. Therefore, maternal investment in a herd of captive Chinese water deer Hydropotes inermis, a relatively small species of cervid, was investigated over 3 years. Except during the lactation period, reproductive females spent about 2-fold more time resting than feeding. During lactation, the amount of time spent feeding increased highly (25.3 min/h during lactation vs 17.3 min/h during the gestation period). Females spent less than 30% of time in communal behaviours with offspring. They did not reject alien fawns during this care period. Frequency and duration of suckling events decreased exponentially from the second week onwards. More than 10% of suckling bouts were non-filial. Prenatal investment leads to a mean litter mass (about 12% of maternal mass) higher than in most cervid species. Postnatal investment in fawns represents a daily mass gain of ca. 85 g/d during the first 2 weeks, without any sexual difference. Female production, timing and synchrony of births and survival of fawns characterized reproductive success. Seventy percent of mature females gave birth, with a mean of 1.9 offspring per female. The sex ratio was even. Births were synchronous, 80% of births occurring in 25 days. In this herd, 0.74 fawn per female was successfully weaned and 0.56 fawn per female survived through their first year. Based on these results we conclude that reproductive strategy of Chinese water deer was efficient and characterized by mother-offspring relationships typical of hiders and high levels of pre- and postnatal investments. This strategy seems typical of small species of cervids without marked sexual dimorphism.[Current Zoology 55(2):102-110,2009].

    Eight atypical Mannheimia isolates were isolated from lesions in roe deer (Capreolus capreolus). Traditional classification based on morphologic and physiologic traits showed that they belong to a distinct biogroup (taxon) within genus Mannheimia. Extensive phenotypic characterization suggested...... that the isolates should be classified as M. granulomatis, although the presence of distinct traits justified their classification into a separate biogroup within this species. Phylogenetic analyses based on 16S rRNA sequences from two roe deer isolates and 41 other Mannheimia strains supported that...... the roe deer isolates form a monophyletic group within M. granulomatis. The lktA genotype was present in all roe deer isolates based on Southern blot analysis, whereas the corresponding beta-hemolytic phenotype was absent in one of these isolates....

    Full Text Available The Javan deer which inhabit Panaitan Island (± 175 Km2 were reintroduced from Peucang Island (± 4.5 Km2 during 1978–1982 (3 males: 13 females. The information of home range and habitat use of these animals were needed for wildlife habitat management especially in the small island habitat. We measured the home range size and habitat use of Javan deer in Peucang Island and Panaitan Island and compared them. The home range size was measured using Minimum Convex Polygon and then the polygon of home ranges were used to measure the habitat use. The results showed that in general the home range size in all age class of Javan deer between both islands did not differ significantly, only subadult males in Peucang Island which have a larger home range size than subadult males in Panaitan Island. Javan deer in Panaitan Island have found suitable conditions.

    Calero-Bernal, Rafael; Verma, Shiv K; Cerqueira-Cézar, Camila K; Schafer, Laurence M; Van Wilpe, Erna; Dubey, Jitender P

    2015-12-01

    Infection with Sarcocystis is common in many species of wild cervids but none is reported from the black-tailed deer (Odocoileus hemionus columbianus). Here, we report Sarcocystis infection in two black-tailed deer from northwest USA for the first time. Sarcocysts were microscopic, up to 556 μm long and mature. The sarcocyst wall was up to 1.39 μm thick and had rectangular 1.17-μm-long villar protrusions, type 17, with thin (230 nm) electron dense ground substance layer. Molecular characterization and phylogenetic analysis indicated that Sarcocystis in the black-tailed deer is related to structurally distinct Sarcocystis species in cervids. A new name, Sarcocystis mehlhorni, is proposed for the Sarcocystis species in black-tailed deer. PMID:26346449

  19. Efficacy of clorsulon and albendazole against Fascioloides magna in naturally infected white-tailed deer.

    Foreyt, W J; Drawe, D L

    1985-12-01

    The efficacy of clorsulon and of albendazole against Fascioloides magna were evaluated in 36 naturally infected white-tailed deer (Odocoileus virginianus) in southern Texas. A single oral dose of clorsulon suspension (12 to 30 mg/kg of body weight; mean = 24 mg/kg) was given to each deer and killed 153 (92%) of 167 mature flukes and 4 (80%) of 5 immature flukes recovered at necropsy. A single oral dose of albendazole paste (17 to 46 mg/kg; mean = 26 mg/kg) was given to each deer and killed 148 (89%) of 167 mature flukes and 4 (67%) of 6 immature flukes recovered at necropsy. In 82 nontreated control deer, 271 live flukes were recovered; dead flukes were not recovered. PMID:4077630

  3. Seasonality of 137Cs in roe deer from Austria and Germany

    Empirical data on the 137Cs activity concentration in meat of roe deer (Capreolus capreolus) roaming in 3 spruce forest areas and one peat bog area are presented and compared. They cover time series of nearly 20 years after a spike contamination in 1986 originating from Chernobyl. A model is presented which considers three soil compartments to describe the change of the availability of 137Cs with time. The time-dependency of the 137Cs activity concentration in meat of roe deer is a combination of two components: (1) an exponential decay and (2) a peak in the second half of each year during the mushroom season. The exponential decay over the years can be described by a sum of two exponential functions. The additional transfer of 137Cs into roe deer during the mushroom season depends on precipitation. On the peat bog the 137Cs activity concentration in roe deer is higher and more persistent than in spruce forest

  7. The effect of immobilizing drugs on adrenal responsiveness to ACTH in Rusa deer.

    Van Mourik, S; Stelmasiak, T

    1984-01-01

    Resting cortisol values in a fully tame Rusa deer (Cervus rusa timorensis) and the influence of two anaesthetics, Rompun and Fentaz, on cortisol levels as well as the response to synthetic ACTH were investigated. The mean level of cortisol in a completely tame Rusa deer was found to be 2.22 ng/ml (SD 1.45 ng/ml n = 36; minimal level recorded was 0.96 ng/ml, maximal level recorded was 9.21 ng/ml). No circadian rhythm of cortisol in plasma was detected. Rompun (xylazine hydrochloride) and/or Fentaz (fentanyl citrate) alone or in combination can be used for immobilization of Rusa deer. Neither Rompun nor Fentaz alone or in combination influences the cortisol response to synthetic ACTH administration. Because of the narrow range for safe dosage for Fentaz the use of Rompun for immobilizing deer is recommended. PMID:6149097

    2012-01-01

    Hainan Eld's deer ( Cervus eldi hainanus ) is a national - level protected species and endemic to China. The stability and development of Eld's deer habitats play a significant role in population growth. Alien invasive plants can affect habitats ir- reversibly over long time periods. We surveyed the alien plants in Hainan Datian National Nature Reserve, where Hainan Eld's deer occur, using line transects and quadrats from 2009 to 2011. We recorded 115 alien plant species of 40 families and 95 genera. Among these, 80 herbs accounted for 70% and most are tropical species, 50% were introduced from the Americas and were mainly distributed in grasslands. The widely distributed alien plants impact the abundance and distribution of native spe- cies and may have a negative effect on Eld's deer food resource in future. We make several recommendations for effective man- agement and conservation. Our survey results can provide a basis for maintaining the stability of Hainan Eld's deer habitat.%海南坡鹿是中国特有的国家Ⅰ级重点保护野生动物,其栖息地的稳定和发展对该物种种群有重要意义。潜在的外来入侵植物会对栖息地产生长期不可恢复的影响。因此,我们于2009—2011年采用样方调查和线路调查相结合的方法对海南坡鹿的栖息地海南大田国家级自然保护区内的外来植物进行了调查,共记录外来植物40科95属115种。其中,草本植物80种,占总物种数的69.6%;不论从科区系还是属区系上看,外来植物的区系分布都具有热带性;50.4%的外来植物产自美洲,在草地中分布最多。保护区内分布广泛的外来植物已对乡土物种产生一定的影响,也将可能对坡鹿的食物资源产生不利影响。根据调查结果,我们提出了一些保护管理建议。

  10. Endemic time-spaces of Finland: Aquatic regimes

    Tero Mustonen

    2014-08-01

    Full Text Available This article explores the endemic time-spaces of Finnish aquatic regimes. More precisely, it examines the socio-ecological relationships between Finns and lakes, rivers, and marshes-mires. First, the 'engine' of endemic time-space research, land use, and occupancy documentation, is explored in the Finnish context. Then two catchment areas, Kokemäenjoki in Western Finland and Vuoksi in Eastern Finland, provide cases which illustrate both past endemic time-spaces and surviving aspects of cultural readings of lakes and rivers. The ongoing winter seining in Lake Puruvesi in North Karelia emerges as an unbroken practice, with deep roots, that maintains the endemic time-spaces of a traditional Finnish relationship with a lake. As industrial uses of catchment areas, zoning, and environmental permitting exclude endemic readings inherent on the land and waterscapes, solutions are explored through mapping, along with its limitations, as a form bridging the gap between local realities and resource extraction.

  11. Winter habitat selection of mule deer before and during development of a natural gas field

    Sawyer, H.; Nielson, R.M.; Lindzey, F.; McDonald, L.L.

    2006-01-01

    Increased levels of natural gas exploration, development, and production across the Intermountain West have created a variety of concerns for mule deer (Odocoileus hemionus) populations, including direct habitat loss to road and well-pad construction and indirect habitat losses that may occur if deer use declines near roads or well pads. We examined winter habitat selection patterns of adult female mule deer before and during the first 3 years of development in a natural gas field in western Wyoming. We used global positioning system (GPS) locations collected from a sample of adult female mule deer to model relative frequency or probability of use as a function of habitat variables. Model coefficients and predictive maps suggested mule deer were less likely to occupy areas in close proximity to well pads than those farther away. Changes in habitat selection appeared to be immediate (i.e., year 1 of development), and no evidence of well-pad acclimation occurred through the course of the study; rather, mule deer selected areas farther from well pads as development progressed. Lower predicted probabilities of use within 2.7 to 3.7 km of well pads suggested indirect habitat losses may be substantially larger than direct habitat losses. Additionally, some areas classified as high probability of use by mule deer before gas field development changed to areas of low use following development, and others originally classified as low probability of use were used more frequently as the field developed. If areas with high probability of use before development were those preferred by the deer, observed shifts in their distribution as development progressed were toward less-preferred and presumably less-suitable habitats.

  12. Susceptible conditions for debarking by deer in subalpine coniferous forests in central Japan

    Hayato Iijima; Takuo Nagaike

    2016-01-01

    Background:Recently, deer have expanded their distribution to higher altitude ranges including subalpine forests. However, culling deer and construction of deer fence in subalpine forests are difficult because of steep slopes and complex topography. Thus it is necessary to clarify the factors which are associated with debarking by deer for the effective protection of subalpine forests. In this study, we examined which factors are associated with debarking by sika deer (Cervus nippon) in subalpine coniferous forests. Methods:We conducted our survey in Minami-Alps National Park, central Japan. We established 24 10 m × 40 m plots and surveyed the occurrence of debarking on saplings>30 cm in height and3 cm in DBH, as well as sapling density within each plot. Minimum distances to nearest grassland of plots were calculated (tentatively assuming grassland would attract deer and would cause high debarking pressure in the surrounding subalpine forests). Results:The mean percentage of debarked live saplings was higher than that of live trees. The mean percentage of debarked saplings which had already died was 81.6 %. Debarking of saplings increased with lower elevation, taller sapling size, and marginally increased near grassland. Sapling density was lower in plots with low basal area of conspecific trees near grassland and differed among species. Sapling density marginally decreased with decreasing elevation and increasing stand tree density. Debarking of trees was positively related to small DBH and low elevation, and marginally increased near grassland and differed among species. Conclusions:Our results suggest that tall saplings in subalpine forests of low elevation or near subalpine grassland were susceptible to debarking by deer and monitoring of these areas may permit the early detection of the impacts of deer in subalpine coniferous forests.

  13. Habitat selection by Eld's deer following relocation to a patchy landscape.

    Duo Pan

    Full Text Available An emerging issue in wildlife conservation is the re-establishment of viable populations of endangered species in suitable habitats. Here, we studied habitat selection by a population of Hainan Eld's deer (Cervus eldi relocated to a patchy landscape of farmland and forest. Hainan Eld's deer were pushed to the brink of extinction in the 1970s, but their population expanded rapidly from 26 to more than 1000 individuals by 2003 through effective reserve protection. As part of a wider relocation and population management strategy, 131 deer were removed from the reserve and reintroduced into a farmland-forest landscape in 2005. Habitat use under a context of human disturbance was surveyed by monitoring 19 radio-collared animals. The majority of deer locations (77% were within 0.6-2 km of villages. Annual home ranges of these collared deer averaged 725 ha (SD 436, which was 55% of the size of the reserve from which they had originated. The annual home ranges contained 54% shrub-grassland, 26% forest and 15% farmland. The relocated deer population selected landscape comprising slash-and-burn agriculture and forest, and avoided both intensively farmed areas and areas containing only forest. Within the selected landscape, deer preferred swiddens and shrub-grasslands. Forests above 300 m in elevation were avoided, whereas forests below 300 m in elevation were overrepresented during the dry season and randomly used during the wet season. Our findings show that reintroduced deer can utilize disturbed habitats, and further demonstrate that subsistence agroforest ecosystems have the capacity to sustain endangered ungulates.

  14. Contrasting responses of web-building spiders to deer browsing among habitats and feeding guilds.

    2008-08-01

    We examined web-building spider species richness and abundance in forests across a deer density gradient to determine the effects of sika deer browsing on spiders among habitats and feeding guilds. Deer decreased the abundance of web-building spiders in understory vegetation but increased their abundance in the litter layer. Deer seemed to affect web-building spiders in the understory vegetation by reducing the number of sites for webs because vegetation complexity was positively correlated with spider density and negatively correlated with deer density. In contrast, the presence of vegetation just above the litter layer decreased the spider density, and deer exerted a negative effect on this vegetation, possibly resulting in an indirect positive effect on spider density. The vegetation just above the litter layer may be unsuitable as a scaffold for building webs if it is too flexible to serve as a reliable web support, and may even hinder spiders from building webs on litter. Alternatively, the negative effect of this vegetation on spiders in the litter may be as a result of reduced local prey availability under the leaves because of the reduced accessibility of aerial insects. The response to deer browsing on web-building spiders that inhabit the understory vegetation varied with feeding guild. Deer tended to affect web-invading spiders, which inhabit the webs of other spiders and steal prey, more heavily than other web-building spiders, probably because of the accumulated effects of habitat fragmentation through the trophic levels. Thus, the treatment of a particular higher-order taxon as a homogeneous group could result in misleading conclusions about the effects of mammalian herbivores. PMID:18801259

    Partial nucleotide sequences of the citrate synthase and 17-kDa genes of Rickettsia helvetica were detected from peripheral blood samples of Sika deer (Cervus nippon yesoensis) in Hokkaido, Japan. Results suggest the presence of a rickettsiemia associated with R. helvetica. This is the first evidence of R. helvetica infection in Sika deer and indicates that this species may represent a potential reservoir host of R. helvetica in Japan. PMID:18263833

    Antler rubbing is a form of behaviour by which deer may damage and ultimately induce mortality of trees. Understanding factors affecting selection of trees for rubbing may contribute to mitigation of negative effects of such behaviour in plantations or woodlands. We analysed characteristics of trees rubbed by red and roe deer along transects established in plantations of Pinus pinaster (Aiton), Pseudotsuga menziesii (Mirbel) Franco, Betula alba L. and Quercus robur L. in Northeast Portugal.

    Abstract In a number of countries, tuberculosis (due to infection with Mycobacterium bovis) is a significant health problem of captive deer. This paper describes outbreaks of bovine tuberculosis in sika deer (Cervus nippon) on two farms in Ireland and the methods used to control the disease. On Farm A, infection was first detected during 1993. The infection was eradicated using a programme of test and removal, in association with segregation of young animals. A second outbreak (also due to in...

  1. Of elephants and blind men: Deer management in the U.S. National Parks

    Porter, W.F.; Underwood, H.B.

    1999-01-01

    Overabundant populations of white-tailed deer (Odocoileus virginianus) are becoming common in the eastern United States. Faced with burgeoning deer populations in eastern parks, the National Park Service (NPS) formulated policy based on its long experience with ungulate management in western parks. That the NPS failed to find a management solution acceptable to its many constituencies was inevitable. Like blind men touching different parts of an elephant and disagreeing about its form, those engaged in the debate about deer management in parks are viewing different parts of the ecological system. None has seen the entire system, and consequently, there is neither common agreement on the nature of the problem nor on the solutions. We explore the quandary of deer management in eastern parks by addressing three questions: (1) Can the National Park Service reconcile its management goals with those of its neighbors? (2) Can thresholds be identified for determining when to intervene in natural processes? (3) Is there a scientific foundation for proceeding with effective management of deer? We argue that reconciling the NPS management with that of state conservation agencies is not possible because management policy guides these agencies in opposite directions: the NPS is charged with limiting human impact on ecological processes, and state agencies are charged with exerting human control over population abundance. Questions about thresholds and a scientific basis for management arise from concern that irrupting deer populations are a manifestation of disrupted natural processes. Several population growth paradigms are at the heart of this ecological question. The science provides no consensus about which of these paradigms are appropriate to deer in eastern ecosystems. Thus, it is premature to expect science to identify if or when natural processes have been disrupted. While the NPS cannot effectively achieve its goals without better science, neither can it wait for

    2012-09-01

    Full Text Available The aim of this research was to determine the profit obtained from breeding of Timor deer commercially. This research was done in East Java. Survey method was used to answer the objective. The study location were selected by purposive sampling. Usually deer was develop in conservation area, but because the area was decrease so the number of deer also decrease. Model of deer raising development should be improved not only for conservation but also for commercial purpose. The optimum deer raising were considered and monitored with a purpose to maximize commercial Timor deer by using Multiple Objective Goal Programming (MOGP to find the Optimistic Rate Estimation. The result of this study showed to get the optimum benefit, it had to be applied together with conservation and commercial effort at the same time. Results of study showed that profit was taken from selling velvet was 164.46%. Profits taken from selling antler was 350.56%, from selling alive deer was 394.28%, from selling recreation tickets was 259.08%, from selling venison1 was 135.98%, and from selling deer leather was 141.24%. Operational cost spent were 168.46% for feeding cost, 213.23% for maintenance cost, and 232.04% for labors’ salaries. The amount of operational cost required in MOGP model, with lower expenses and commercial priority were 185.54% for feeding cost, 253.13% for maintenance cost, and 246.95% for paying labors’ salaries. The MOGP model result with commercial priority reached 335.21%, while in MOGP model with lower costs and commercial priority gave profit for breeders up to 381.26%.

    QIAO Jianfang; YANG Weikang; GAO Xingyi

    2006-01-01

    In order to determine the natural diet and food habitat use of Tarim red deer (Cervus elaphus yarkandensis), a study was carried out in Qiemo, Xinjiang, China from October 2000 to June 2001. Direct observation combined with faecal analysis method was used to determine the natural diet of red deer. 15 different species of plant were identified as food items. Among them, 13 species of plants were identified in winter diet and 9 species in summer. Red deer consumed a wider range of species in winter because of their nutrient requirement as well as the shortage of food and the scarcity of high-quality forage in the study area. Phragmites communis, Glycyrrhiza inflata and populus diversifolia were frequently present in the deer's diet whenever in winter and summer. Among them, Phragmites communis was the most abundant plant in the area and was included in the deer's diet. Observation on food selection frequency of captive Tarim red deer showed that Populus diversifolia was the first preferred species. However, this food was limited in the study area. Five food habitat types were found in the study area according to plant association: (1)Phragmites communis-Tamarix ramosissima association, (2) Tamarix ramosissima-Halostachys caspica association, (3) Tamarix ramosissima-Phragmites communis association, (4) Populus diversifoliaPhragmites communis association, (5) Burned area.Among them, Phragmites communis-Tamarix ramosissima association (reed meadow and reed marsh)was preferred to other types within the study area whenever in summer and winter. Dense reed cover could reduce the chance of detection from predator and obstruct attack from predator. Furthermore, under the cover of the reed, Tarim red deer was protected from direct solar radiation during the hours of www. scichina.com www.springerlink.com hot day in summer. The reed meadow and marsh was preferred, presumably because the red deer could minimize their movements while searching for food, water and cover.

    Gastrointestinal (GI) nematodes are among the most important causes of production loss in farmed ruminants, and anthelmintic resistance is emerging globally. We hypothesized that wild deer could potentially act as reservoirs of anthelmintic-resistant GI nematodes between livestock farms. Adult abomasal nematodes and faecal samples were collected from fallow (n = 24), red (n = 14) and roe deer (n = 10) from venison farms and areas of extensive or intensive livestock farming.

  9. Life in the Fast Lane: Road Crossing Behavior of Mule Deer in a Wildland-Urban Interface

    In 2009, approximately 260,000 animal-vehicle collisions were reported in the United States, resulting in 12,000 human injuries and 173 human fatalities. Research has focused on identifying factors associated with high densities of animal-vehicle collisions, including variables such as traffic speed and volume, road design, topographic features, vegetative cover, and local deer or elk (Cervus elaphus) abundance. The purposes of this study were to document how often and where mule deer (Odocoileus hemionus) crossed roads in a western United States wildland-urban interface area, and to relate deer road-crossing behavior to deer-vehicle collision locations. Seven adult mule deer (four males [M] and three females [F]) were captured and collared with GPS-enabled collars during December 2001 and January 2002. Five of the seven deployed collars were recovered. None of the roads in the study area appeared to act as a substantial barrier to deer passage. Deer home ranges straddled highways and primary, secondary, and tertiary arterial roads. Deer crossed all types of roads. The average number of times deer crossed road during 24 hours of monitoring ranged from 2.1 to 7.0. Deer in the Los Alamos townsite avoided crossing roads during day and before sunset. Deer-vehicle accidents occurred at 350 percent of the level expected after sunset. All other time periods had fewer accidents than expected. The distribution of accidents across time periods was not similar to the distribution of road crossings across time periods for any deer. Within Los Alamos County there was a clear trend for deer-vehicle collisions to occur on roads with speed limits > 35 mph. Deer in the townsite frequently crossed roads with lower speed limits; therefore, the reason for the paucity of accidents along these roads was evidently the ability of drivers to detect deer (or the ability of deer to detect vehicles) and respond before an accident occurred. There was a significant but not strong correlation

    When a pathogen infects a number of different hosts, the process of determining the relative importance of each host species to the persistence of the pathogen is often complex. Removal of a host species is a potential but rarely possible way of discovering the importance of that species to the dynamics of the disease. This study presents the results of a 12-year programme aimed at controlling brucellosis in cattle, sheep and goats and the cascading impacts on brucellosis in a sympatric population of red deer (Cervus elaphus) in the Boumort National Game Reserve (BNGR; NE Spain). From February 1998 to December 2009, local veterinary agencies tested over 36 180 individual blood samples from cattle, 296 482 from sheep and goats and 1047 from red deer in the study area. All seropositive livestock were removed annually. From 2006 to 2009 brucellosis was not detected in cattle and in 2009 only one of 97 red deer tested was found to be positive. The surveillance and removal of positive domestic animals coincided with a significant decrease in the prevalence of brucellosis in red deer. Our results suggest that red deer may not be able to maintain brucellosis in this region independently of cattle, sheep or goats, and that continued efforts to control disease in livestock may lead to the eventual eradication of brucellosis in red deer in the area.

  11. Prevalence of Dermatophytes in Red Deer (Cervus elaphus in The Stelvio National Park, Italy

    2015-10-01

    Full Text Available Dermatophytosis has been described in wildlife, but the literature reporting dermatophyte prevalence in deer is incomplete. To determine the prevalence of dermatophytes and to evaluate the hypothetical role of asymptomatic carriers hair samples were collected from 30 legally hunted wild red deer (Cervus elaphus in the Stelvio National Park, Italy. All deer were visually examined for dermatologic lesions and the coat was brushed using a modified Mackenzie collection method. A small sample of hair was used for direct microscopical examination and subsequently fungal culture was performed on the hair samples. Macroscopic and microscopic examinations were used to identify dermatophytes, saprophytic fungi and yeasts. None of the deer had visible cutaneous lesions. No dermatophyte spores or hyphae were found on direct microscopical examination and, when hair samples were cultured, dermatophytes were not demonstrated in any sample. Only saprophytic fungi were grown, predominantly Alternaria spp., Mucor spp., Cladosporium spp. These results did not reveal the presence of asymptomatic carriers of dermatophytes in the deer sample population of Stelvio National Park and suggest that it is unlikely that, at least in the investigated geographical area, the red deer act a reservoir for transmission of dermatophytes to other wild animals, livestock or people living locally

    Spatial gradients in human activity, coyote activity, deer activity, and deer herbivory provide an unusual type of evidence for a trophic cascade. Activity of coyotes, which eat young mule deer (fawns), decreased with proximity to a remote biological field station, indicating that these predators avoided an area of high human activity. In contrast, activity of adult female deer (does) and intensity of herbivory on palatable plant species both increased with proximity to the station and were positively correlated with each other. The gradient in deer activity was not explained by availabilities of preferred habitats or plant species because these did not vary with distance from the station. Does spent less time feeding when they encountered coyote urine next to a feed block, indicating that increased vigilance may contribute, along with avoidance of areas with coyotes, to lower herbivory away from the station. Judging from two palatable wildflower species whose seed crop and seedling recruitment were greatly reduced near the field station, the coyote-deer-wildflower trophic cascade has the potential to influence plant community composition. Our study illustrates the value of a case-history approach, in which different forms of ecological data about a single system are used to develop conceptual models of complex ecological phenomena. Such an iterative model-building process is a common, but underappreciated, way of understanding how ecological systems work.

    Full Text Available The general objective of the study was to provide current information on grassland communities as deer habitat and its future development plan for a sustainable forage management in upland Kebar, Papua. Quantitative estimation of forage production was carried out by measuring a biomass harvest in fresh weight bases, while occasional observations on ranging deer were done within habitat range with the aid of 7x50 binoculars verified by actual visitation of grazed area. The study indicated that Kebar was the only grazing area of deer varies in low layer vegetation composition that comprised of eleven grass species and five legume species. Imperata cylindrica, Paspalum conjugatum, Themeda arguens, Melinis minutiflora and Cyperus rotundus were identified as food plant of deer in Kebar. Among these species T. arguens, M. minutiflora, C. rotundus and I. cylindrica were the most preferred species consumed by deer. The biomass harvest (species productivity was 30.36 kg/ha fresh weight, while deer food productivity in the grassland was slightly lower (26.70 kg/ha than total productivity of the grassland. The major drainage area is Kasi River, but two other rivers across this valley (Api River, Apriri River are also supply water to the swampy area.

  14. Response of mule deer to habitat modification near natural gas development

    2012-09-01

    Full Text Available Mule deer (Odocoileus hemionus are known to shift habitat use in response to environmental modifications, including those associated with energy development. Their specific behavioral responses, however, and capacities to habituate to particular aspects of energy development have not been effectively studied. We examined mule deer response to habitat alteration near natural gas wells in Las Animas County, Colorado, USA in 2008—2010, an area experiencing development for extraction of natural gas. We created 10-1 ha openings in forests adjacent to 10 wells by removing standing trees in 2008, with concomitant establishment of 10 1-ha control sites adjacent to the same wells. On each site, we estimated deer use, indexed by pellet density, before and after tree removal. Concurrently, we measured plant production, cover, nutritional quality, species composition and biomass removed by deer and other large herbivores. Species richness and diversity and graminoid and forb cover and biomass increased on cut sites following tree removal. Use increased following tree removal on cut and control sites, but was greater on cut sites in 2010. Herbivores removed negligible quantities of vegetation on control sites in both years, suggesting that control sites may have been used primarily for concealment. Mule deer demonstrated the behavioral capacity to habituate to habitat modifications and other environmental changes associated with development for the extraction of energy. Managing forage and habitat availability appears to have the potential to affect the type of response and degree of habituation by mule deer to such development.

  15. Comparison of the prevalence of Crimean-Congo hemorrhagic fever virus in endemic and non-endemic Bulgarian locations

    2013-12-01

    Full Text Available Background & objectives: The Balkans is an endemic region for Crimean-Congo hemorrhagic fever (CCHF, caused by the CCHF virus (CCHFV. Several Bulgarian regions comprised of smaller locations are categorized either as endemic or non-endemic for CCHF. However, little is known about the dynamics that underlie the development of endemicity within the locations throughout the years. Methods: Seven locations categorized as endemic in one central Bulgarian region (Stara Zagora were compared to seven non-endemic areas. During the period 2006-12, a total of 1775 blood samples from cattle, were tested for anti-CCHFV antibodies using an indirect immunofluorescence antibody assay. Also, the infestation of 617 mature ticks for CCHFV was studied using a combination of an immunofluorescence haemocytes assay and molecularvirological methods. Results: Anti-CCHFV antibodies were established in 7.89% (140/1775 of the sera. The average CCHFV-infestation in the ticks was 1.46% (9/617. CCHFV was detected in three tick species: H.m. marginatum (3.73%, 6/161, being the main vector of the infection; R. sanguineus (1.63%, 2/123; and I. ricinus (1.96%, 1/51. Interpretation & conclusion: The data for the endemic and non-endemic locations did not reveal significant differences for the prevalence of CCHFV. Mosaic dispersion of the virus was determined in the studied region and the results did not vary significantly throughout the investigated years.

  17. Changes in distribution area of Korean musk deer (Moschus moschiferus parvipes) from 1950s to 1999 in South Korea

    2002-01-01

    Based on the literature reviews and questionnaire, field survey on the species, feces, and tracks in non-snow season and snow season of Korean musk deer from February to December of 1999 in South Korea (Cultural Properties Administration 1999), the authors summarized the change of distribution area and number of Korean musk deer from 1950s to 1999. The results showed that the distribution area of Korean musk deer (Moschus moschiferus parvipes) was sharply decreased from 1950s to 1999 in South Korea. Due to the road and forest road construction in the habitat of Korean musk deer, the musk deer habitats were fragmented and lost. And the illegal capture for economic benefits was the main reason of decreases in number of individuals and habitats of this species. Forest roads in high elevation area were also used as the passages for illegal captures. For the conservation and protection of Korean musk deer, strict regulation of illegal capture is urgently needed.

  18. A Paleozoological Perspective on White-Tailed Deer ( Odocoileus virginianus texana) Population Density and Body Size in Central Texas

    Wolverton, Steve; Kennedy, James H.; Cornelius, John D.

    2007-04-01

    Archaeological and paleontological datasets are used in conservation to add time-depth to ecology. In central Texas, several top carnivores including prehistoric Native American hunters have been extirpated or have had their historic ranges restricted, which has resulted in pest-level white-tailed deer ( Odocoileus virginianus texana) populations in some areas. Differences in body size of deer between prehistory and modernity are expected, given that a lack of predation likely has increased intraspecific competition for forage among deer, resulting in smaller body size today. In fact, modern deer from settings without harvest pressure are significantly smaller than those from harvested areas and from prehistoric deer. From a natural history perspective, this research highlights potential evolutionary causes and effects of top-predator removal on deer populations and related components of biological communities in central Texas.

  19. Urinary iodine excretion in relation to goiter prevalence in households of goiter endemic and non endemic regions of Ethiopia

    A Survey of goiter prevalence, among population of five endemic and four non endemic regions of Ethiopia was carried out prior to the distribution of iodate d salt. urine samples were collected from 327 subjects selected by systematic random sampling from endemic and 276 taken as non endemic. The lowest mean urinary iodine excretion (UIE) value was recorded in Bure (22 micro gl/day) and the highest in Alemmaya (148 micro gl/day). The highest goiter rate ( percent TGR) was recorded in Sawla 55.6 %) and the lowest (0.6 %) in Yabello. Iodine content of drinking was in the range of 0.4 - 48.5 micro gl. Iodine content of water source was correlated positively ( r0.8399) with the mean of UIE and TGR, however, indicates that sites considered as non endemic seem to be affected by iodine deficiency. The study results urge the need for intervention in controlling Iodine Deficiency Disorders. 3 tab

  20. Efficacy of a 15-Strand High-Tensile Electric Fence to Control White-tailed Deer Movements

    2009-06-01

    Full Text Available Although, high-tensile electric fences (HTEF have gained in popularity as a low-cost alternative to traditional fence designs, little research has focused on the effects of HTEF on white-tailed deer (Odocoileus virginianus. Our objectives were to: determine the efficacy of a HTEF to control deer movements and evaluate its influence on deer spatial dynamics. We conducted our study on the Samuel Roberts Noble Foundation Wildlife Unit located in Oklahoma, USA. An electric 15-strand, 2.5 m high fence was erected around the study area in 1992. We captured and ear-tagged 419 deer from 1993-2005 and fitted 35 of these deer (19 females, 16 males with GPS collars during winter 1998-2004. Eight of 35 radio-collared deer (23% crossed through the fence a total of 15 times and returned 13 times. Most fence crossings were at or near a hole or water gap (75%; n = 21 while 21.4% (n = 6 crossed through the electric strands. Twenty four of 419 (6% ear-tagged deer were reported dead or harvested off of the property over 13 years. We found ≥13 deer core areas and ≥29 of home ranges bordered the fence. Core area and home range sizes of males and females were larger for deer associated with the fence compared to deer not associated with the fence. The percentage of deer FK core area and home range perimeters in common with the fence was 17 and 28%, respectively. It appears deer were tolerable of the fence and willing to attempt to cross at weak locations (i.e., holes and water gaps. If fully maintained, the 15-strand HTEF would have been a safe and effective alternative to more traditional and expensive fence designs.

    Assemblages of introduced taxa provide an opportunity to understand how abiotic and biotic factors shape habitat use by coexisting species. We tested hypotheses about habitat selection by two deer species recently introduced to New Zealand’s temperate rainforests. We hypothesised that, due to different thermoregulatory abilities, rusa deer (Cervus timorensis; a tropical species) would prefer warmer locations in winter than red deer (Cervus elaphus scoticus; a temperate species). Since adult m...

    Pathogens can be critical drivers of the abundance and distribution of wild animal populations. The presence of an overdispersed pathogen load distribution between hosts (where few hosts harbour heavy parasite burdens and light infections are common) can have an important stabilizing effect on host-pathogen dynamics where infection intensity determines pathogenicity. This may potentially lead to endemicity of an introduced pathogen rather than extirpation of the host and/or pathogen. Overdispersed pathogen load distributions have rarely been considered in wild animal populations as an important component of the infection dynamics of microparasites such as bacteria, viruses, protozoa and fungi. Here we examined the abundance, distribution and transmission of the model fungal pathogen Batrachochytrium dendrobatidis (Bd, cause of amphibian chytridiomycosis) between wild-caught Litoria rheocola (common mist frogs) to investigate the effects of an overdispersed pathogen load distribution on the host population in the wild. We quantified host survival, infection incidence and recovery probabilities relative to infectious burden, and compared the results of models where pathogen overdispersion either was or was not considered an important feature of host-pathogen dynamics. We found the distribution of Bd load between hosts to be highly overdispersed. We found that host survival was related to infection burden and that accounting for pathogen overdispersion allowed us to better understand infection dynamics and their implications for disease control. In addition, we found that the pattern of host infections and recoveries varied markedly with season whereby (i) infections established more in winter, consistent with temperature-dependent effects on fungal growth, and (ii) recoveries (loss of infection) occurred frequently in the field throughout the year but were less likely in winter. Our results suggest that pathogen overdispersion is an important feature of endemic

  5. Advances in methods for measuring patterns of endemic plant diversity

    Full Text Available Endemism, the restriction of a taxon’s distribution to a specified geographical area, is central to the study of biogeography. Understanding endemism not only concerns a number of evolutionary and biogeographical issues, but also plays an important role in maintaining biodiversity and in the selection of priority areas for conservation. In recent years, various measures and analytical methods have been used to investigate patterns of endemism for various taxa from different regions. The emergence of these new measurements has benefited from the construction of phylogenetic trees and the implementation of data from spatial statistics. Some of these measures, such as phylogenetic diversity, phylogenetic endemism, and biogeographically weighted evolutionary distinctiveness deserve much more attention. Here, we review progress in the methodology used to measure the distribution patterns of endemism. These metrics have generally developed from a single time or space perspective to space-time united patterns. Specifically, the metrics include species richness, phylogenetic diversity and evolutionary distinctiveness, plus all there in combination as well as the weight of species range size. Moreover, we propose that studies on the distribution patterns of Chinese endemic taxa should pay attention to species diversity, phylogenetic diversity, species β-diversity, and phylogenetic β-diversity. In particular, model simulation analysis should be emphasized and implemented during investigations. These studies will provide fundamental knowledge for comprehensive recognition of scale-induced differences and for the detection of mechanisms underlying the distribution patterns of endemic taxa, and therefore provide theoretical support for biodiversity conservation.

  6. Large Impact of Eurasian Lynx Predation on Roe Deer Population Dynamics

    Andrén, Henrik; Liberg, Olof

    2015-01-01

    The effects of predation on ungulate populations depend on several factors. One of the most important factors is the proportion of predation that is additive or compensatory respectively to other mortality in the prey, i.e., the relative effect of top-down and bottom-up processes. We estimated Eurasian lynx (Lynx lynx) kill rate on roe deer (Capreolus capreolus) using radio-collared lynx. Kill rate was strongly affected by lynx social status. For males it was 4.85 ± 1.30 S.E. roe deer per 30 days, for females with kittens 6.23 ± 0.83 S.E. and for solitary females 2.71 ± 0.47 S.E. We found very weak support for effects of prey density (both for Type I (linear) and Type II (non-linear) functional responses) and of season (winter, summer) on lynx kill rate. Additionally, we analysed the growth rate in a roe deer population from 1985 to 2005 in an area, which lynx naturally re-colonized in 1996. The annual roe deer growth rate was lower after lynx re-colonized the study area, but it was also negatively influenced by roe deer density. Before lynx colonized the area roe deer growth rate was λ = 1.079 (± 0.061 S.E.), while after lynx re-colonization it was λ = 0.94 (± 0.051 S.E.). Thus, the growth rate in the roe deer population decreased by Δλ = 0.14 (± 0.080 S.E.) after lynx re-colonized the study area, which corresponded to the estimated lynx predation rate on roe deer (0.11 ± 0.042 S.E.), suggesting that lynx predation was mainly additive to other mortality in roe deer. To conclude, this study suggests that lynx predation together with density dependent factors both influence the roe deer population dynamics. Thus, both top-down and bottom-up processes operated at the same time in this predator-prey system. PMID:25806949

    Full Text Available Macrophytes are a critical component of freshwater ecosystems and are often eaten by cervids. However, the impact of cervids on macrophytes is not well known. In this study, we investigated the effect of sika deer (Cervus nippon yesoensis on the endangered macrophyte Ranunculus nipponicus var. submersus in a spring stream in southwestern Hokkaido, Japan. We monitored the frequency of stream habitat use by deer by using sensor cameras in photography mode for four seasons. We also monitored deer feeding behavior on R. nipponicus var. submersus using sensor cameras in movie mode. To quantitatively evaluate the impact of deer on R. nipponicus var. submersus, we conducted a field experiment in which deer were excluded from part of the stream. We selected 10 pairs of adjacent patches of R. nipponicus var. submersus and set up exclosures covering one patch in each pair. We assessed the frequency of deer feeding and trampling on the control patches using the sensor cameras in photography mode and measured the mean macrophyte stem length in the exclosure and control patches every month for four seasons. To compare abiotic conditions between the exclosure and control patches, we investigated canopy openness, water depth, water temperature, electrical conductivity, pH, current velocity, and water quality at each patch during the growing season. The frequency of deer in the stream habitat was higher from spring to summer than in other seasons. Direct evidence of deer feeding behavior on R. nipponicus var. submersus was recorded using the sensor cameras. Deer often fed on and trampled on the control patches, particularly from spring to summer. The R. nipponicus var. submersus stem length was longer in the exclosure patches than in control patches (P 0.189. Stem growth of R. nipponicus var. submersus differed among seasons (P <0.001, and was low from winter to spring. In addition, exclosure and seasonality significantly affected stem length (P <0.001, and the

    We constructed and analyzed the RBG-banded karyotype of five deer species: Chital (Axis axis), White-lipped deer (Cervus albirostris), Rusa deer (Cervus timorensis russa), Sambar deer (Cervus unicolor) and Eld's deer (Cervus eldi siamensis). Among these five species, only Eld's deer had been previously karyotyped using R-banding. In order to identify all the chromosome correspondences with cattle and precisely which chromosome arms are involved in Robertsonian translocations, we compared the karyotypes of these five species with those of the closely related and well-characterized species, cattle (Bos taurus) and Vietnamese Sika deer (Cervus nippon pseudaxis). Among these six deer species (the five above plus the Vietnamese Sika deer), we found thirteen different Robertsonian translocations involving nineteen different chromosome arms. Thirteen chromosome arms were identified by comparison of R-banding patterns only and the remaining six were either confirmed or identified by FISH-mapping of bovine or caprine probes previously localized in cattle. Finally, we observed that five of the thirteen Robertsonian translocations are shared by at least two species and that some chromosome arms are more frequently involved in Robertsonian translocations than others.

    2015-01-01

    The demographic characteristics of an amphibian population fluctuate independently over time, mainly in response to the temporal variation of environmental factors, especially precipitation and temperature. These temporal fluctuations may contribute to the size of an amphibian population and could be used to determine the current conservation status of a species. During a five year (2004-2008) period, we studied the relative abundance, sex ratio, and age-sex structure of a population of metamorphosed individuals of the endemic treefrog Hyla eximia in Central Mexico. We also studied the species' relationship with climatic variables such as temperature and precipitation. We found an interannual constant abundance during the study period. However, interannual differences were observed in the population structure by age-sex category (males, females, or juveniles), with decreased abundance of males and juveniles during the rainy months (August-November). The annual abundance of H. eximia was positively correlated with rainfall, but negatively with monthly temperature. We found the sex ratio was male-biased (2:1), except for year 2008. Also, differences in snout-vent length (SVL) were found between years, suggesting changes in recruitment of new individuals. We conclude that variations in abundance, and frequencies by age-sex category, of H. eximia are related to seasonal variations in temperature and precipitation characteristics of temperate zones. However, this temporal stability may suggest that anurans have an unusual capacity to persist even in the face of human-induced habitat change. PMID:26421242

  10. REVIEW: Endemic plants of serpentine soils

    SUDARMONO

    2007-10-01

    Full Text Available Plant adaptation to serpentine soils is a system ideal for studies in evolutionary ecology. Serpentine soils are characterized by low calcium to magnesium ratios with Ca at significantly lower concentrations relative to surrounding areas. Although some variation occurs between sites which identified three collective traits: poor plant productivity, high rates of endemism and vegetation type distinct from those of neighboring areas. The several morphological feature characteristic of serpentine-tolerant species is possess xeromorphic foliage, including reduced leaf size and sclerophylls, the stature is significantly reduced relative to counterparts on non serpentine soil and root systems of species growing on and off serpentine sites are often more developed on serpentine soils than on neighboring soils. Serpentine soils are ubiquitous, but patchily distributed and thus promote geographic isolation. Adaptation to edaphic conditions may also beget reproductive isolation. Adaptive mutation might be influenced frequently from related species inhabiting surrounding areas. For the future studies involving serpentine systems merge the fields of ecology, evolution, physiology, and genetics required for serpentine adaptation.

  11. Geography, deer, and host biodiversity shape the pattern of Lyme disease emergence in the Thousand Islands Archipelago of Ontario, Canada.

    Lisa Werden

    Full Text Available In the Thousand Islands region of eastern Ontario, Canada, Lyme disease is emerging as a serious health risk. The factors that influence Lyme disease risk, as measured by the number of blacklegged tick (Ixodes scapularis vectors infected with Borrelia burgdorferi, are complex and vary across eastern North America. Despite study sites in the Thousand Islands being in close geographic proximity, host communities differed and both the abundance of ticks and the prevalence of B. burgdorferi infection in them varied among sites. Using this archipelago in a natural experiment, we examined the relative importance of various biotic and abiotic factors, including air temperature, vegetation, and host communities on Lyme disease risk in this zone of recent invasion. Deer abundance and temperature at ground level were positively associated with tick abundance, whereas the number of ticks in the environment, the prevalence of B. burgdorferi infection, and the number of infected nymphs all decreased with increasing distance from the United States, the presumed source of this new endemic population of ticks. Higher species richness was associated with a lower number of infected nymphs. However, the relative abundance of Peromyscus leucopus was an important factor in modulating the effects of species richness such that high biodiversity did not always reduce the number of nymphs or the prevalence of B. burgdorferi infection. Our study is one of the first to consider the interaction between the relative abundance of small mammal hosts and species richness in the analysis of the effects of biodiversity on disease risk, providing validation for theoretical models showing both dilution and amplification effects. Insights into the B. burgdorferi transmission cycle in this zone of recent invasion will also help in devising management strategies as this important vector-borne disease expands its range in North America.

    Parathyroid-hormone-related peptide (PTHrP) is an important regulator of chondrocyte differentiation in growth plates but little is known about its role in deer antler cartilage. The aim of the present study was to use the deer antler as a model to determine the possible role of PTHrP in regulating chondrocyte differentiation of deer antler. PTHrP and its receptor PTH1R mRNA were highly expressed in the perichondrium and cartilage of sika deer antler, as shown by in situ hybridization. Chondrocytes of deer antler were identified by toluidine blue staining of glycosaminoglycan and immunocytochemical staining of type II collagen (Col II). Treatment with PTHrP (1-34) reduced the expression of prehypertrophic chondrocyte marker Col IX and hypertrophic chondrocyte marker Col X. In order to confirm the mechanism of action of PTHrP, we initially examined the expression of cyclin D1, Bcl-2 and runt-related transcription factor 2 (Runx2) in sika deer antler by in situ hybridization and found that cyclin D1, Runx2 and Bcl-2 mRNA were also expressed in antler chondrocytes. Exogenous PTHrP induced the expression of cyclin D1 and Bcl-2 mRNA by various signalling pathways, whereas it inhibited Runx2 expression through PKA, p38MAPK, MEK and PI3K signalling pathways. Thus, PTHrP might promote the proliferation of antler chondrocytes and prevent their differentiation; it might furthermore influence the growth and development of sika deer antler. PMID:23824099

    Wild species are essential hosts for maintaining Ixodes ticks and the tick-borne diseases. The aim of our study was to estimate the prevalence, the rate of co-infection with Babesia, Bartonella, and Anaplasma phagocytophilum, and the molecular diversity of tick-borne pathogens in roe deer in Poland. Almost half of the tested samples provided evidence of infection with at least 1 species. A. phagocytophilum (37.3%) was the most common and Bartonella (13.4%) the rarest infection. A total of 18.3% of all positive samples from roe deer were infected with at least 2 pathogens, and one-third of those were co-infected with A. phagocytophilum, Bartonella, and Babesia species. On the basis of multilocus molecular studies we conclude that: (1) Two different genetic variants of A. phagocytophilum, zoonotic and nonzoonotic, are widely distributed in Polish roe deer population; (2) the roe deer is the host for zoonotic Babesia (Bab. venatorum, Bab. divergens), closely related or identical with strains/species found in humans; (3) our Bab. capreoli and Bab. divergens isolates differed from reported genotypes at 2 conserved base positions, i.e., positions 631 and 663; and (4) this is the first description of Bart. schoenbuchensis infections in roe deer in Poland. We present 1 of the first complex epidemiological studies on the prevalence of Babesia, Bartonella, and A. phagocytophilum in naturally infected populations of roe deer. These game animals clearly have an important role as reservoir hosts of tick-borne pathogens, but the pathogenicity and zoonotic potential of the parasite genotypes hosted by roe deer requires further detailed investigation.

    2016-04-13

    Red deer (Cervus elaphus) have played a key role in human societies throughout history, with important cultural significance and as a source of food and materials. This relationship can be traced back to the earliest human cultures and continues to the present day. Humans are thought to be responsible for the movement of a considerable number of deer throughout history, although the majority of these movements are poorly described or understood. Studying such translocations allows us to better understand ancient human-wildlife interactions, and in the case of island colonizations, informs us about ancient human maritime practices. This study uses DNA sequences to characterise red deer genetic diversity across the Scottish islands (Inner and Outer Hebrides and Orkney) and mainland using ancient deer samples, and attempts to infer historical colonization events. We show that deer from the Outer Hebrides and Orkney are unlikely to have originated from mainland Scotland, implying that humans introduced red deer from a greater distance. Our results are also inconsistent with an origin from Ireland or Norway, suggesting long-distance maritime travel by Neolithic people to the outer Scottish Isles from an unknown source. Common haplotypes and low genetic differentiation between the Outer Hebrides and Orkney imply common ancestry and/or gene flow across these islands. Close genetic proximity between the Inner Hebrides and Ireland, however, corroborates previous studies identifying mainland Britain as a source for red deer introductions into Ireland. This study provides important information on the processes that led to the current distribution of the largest surviving indigenous land mammal in the British Isles. PMID:27053752

    Full Text Available Abstract Background Bovine viral diarrhea virus (BVDV infections continue to cause significantly losses in the deer population. Better isolation and identification of BVDV from sika deer may contribute significantly to the development of prophylactic therapeutic, and diagnostic reagents as well as help in prevention and control of BVDV. However, isolation and identification of BVDV from sika deer is seldom reported in literature. In this study, we collected some samples according to clinical sign of BVDV to isolation and identification of BVDV from sika deer. Results we isolated a suspected BVDV strain from livers of an aborted fetus from sika deer in Changchun (China using MDBK cell lines, named as CCSYD strain, and identified it by cytopathic effect (CPE, indirect immunoperoxidase test (IPX and electron microscopy(EM. The results indicated that this virus was BVDV by a series of identification. The structural proteins E0 gene was cloned and sequenced. The obtained E0 gene sequence has been submitted to GenBank with the accession number: FJ555203. Alignment with other 9 strains of BVDV, 7 strains of classical swine fever virus (CSFV and 3 strains of border disease virus(BDV in the world, showed that the homology were 98.6%-84.8%, 76.0%-74.7%, 76.6%-77.0% for nucleotide sequence, respectively. The phylogenetic analysis indicated that new isolation and identification CCSYD strain belonged to BVDV1b. Conclusion To the best of our knowledge, this is the first report that BVDV was isolated and identified in sika deer. This current research contributes development new BVDV vaccine to prevent and control of BVD in sika deer.

    2015-01-01

    The objectives of the present study were to assess heavy metal cadmium (Cd), lead (Pb) and organochlorine pesticide concentrations in tissues of red deer (Cervus elaphus) and wild boar (Sus scrofa) from nine hunting areas and to evaluate related risk factors for the host animal. Over a period of 2 years, a total of 1055 and 210 masseters, 424 and 201 livers, 642 and 152 kidneys were collected from wild boar and red deer, respectively, and concentrations of Cd, Pb and organochlorine pesticides were determined. Comparing the two species, Cd concentration in the kidney (3.72 mg/kg), liver (0.67 mg/kg) and muscle (0.02 mg/kg) of wild boar was found to be significantly higher than in the organs of red deer (1.02 mg/kg in the kidneys, 0.07 mg/kg in the liver and 0.006 mg/kg in muscle). Mean Pb concentrations were found to be similar in both animals, with 0.39, 0.52 and 2.60 mg/kg detected in the wild boar kidney, liver and muscle, respectively, and 0.24, 0.21 and 2.04 mg/kg in the respective organs of the red deer. No difference in concentrations were found based on age class, location of tissue sample or contaminant in the case of wild boar. By contrast, a significantly lower Cd concentration was found in the kidney of the young red deer. The search for organochlorine pesticides in both red deer and wild boar produced negative results with values below the limits of detection. Due to the high levels of renal Cd and muscle Pb detected in wild boar and red deer, further research needs to be carried out in an effort to identify the source of contamination and preserve the health of animals and humans.

    2014-08-01

    A population of approximately 70,000 rusa deer (Cervus timorensis russa) represents the most important mammal species reared for food on the island of Mauritius, being the main source of red meat for the local population. However, very limited information is available on the circulation of pathogens affecting the productivity and health of this species. To produce baseline data on the circulation of infectious pathogens in rusa deer under production, a serological survey and/or direct pathogen detection for six selected infectious diseases was undertaken in 2007 in a sample of 53% of the herds reared in semi-free-ranging conditions in hunting estates. Seropositive results were recorded for Johne's disease with an indirect ELISA test (1.7%, n = 351), heartwater with an immunofluorescence antibody test (IFAT) (95.5%, n = 178) and leptospirosis with a Microscopic Agglutination Test (MAT) (25.9%, n = 363). Significant associations were found between seroprevalence to some of the leptospiral serogroups detected (Tarassovi, Pomona, Sejroe and Mini) and age of the animals, animal density or location of the estates (being more prevalent in hotter and more humid areas). In addition, Mycobacterium bovis and M. avium subspecies paratuberculosis were confirmed in two deer carcasses by culture and PCR, respectively. No antibodies against Brucella spp. nor Rift Valley Fever virus were detected with the use of respective indirect ELISA's. The results obtained suggest that the population of rusa deer from Mauritius is exposed to a wide range of pathogens which may affect their productivity. In addition, the results highlight the potential public health risks incurred by deer industry workers and consumers. This survey fills an important gap in knowledge regarding the health of tropical deer meat in Mauritius and justifies the need to implement more regular surveys of selected pathogens in the deer population.

  18. Generation of competent bone marrow-derived antigen presenting cells from the deer mouse (Peromyscus maniculatus

    Farrell Regina M

    2004-09-01

    Full Text Available Abstract Background Human infections with Sin Nombre virus (SNV and related New World hantaviruses often lead to hantavirus cardiopulmonary syndrome (HCPS, a sometimes fatal illness. Lungs of patients who die from HCPS exhibit cytokine-producing mononuclear infiltrates and pronounced pulmonary inflammation. Deer mice (Peromyscus maniculatus are the principal natural hosts of SNV, in which the virus establishes life-long persistence without conspicuous pathology. Little is known about the mechanisms SNV employs to evade the immune response of deer mice, and experimental examination of this question has been difficult because of a lack of methodologies for examining such responses during infection. One such deficiency is our inability to characterize T cell responses because susceptible syngeneic deer mice are not available. Results To solve this problem, we have developed an in vitro method of expanding and generating competent antigen presenting cells (APC from deer mouse bone marrow using commercially-available house mouse (Mus musculus granulocyte-macrophage colony stimulating factor. These cells are capable of processing and presenting soluble protein to antigen-specific autologous helper T cells in vitro. Inclusion of antigen-specific deer mouse antibody augments T cell stimulation, presumably through Fc receptor-mediated endocytosis. Conclusions The use of these APC has allowed us to dramatically expand deer mouse helper T cells in culture and should permit extensive characterization of T cell epitopes. Considering the evolutionary divergence between deer mice and house mice, it is probable that this method will be useful to other investigators using unconventional models of rodent-borne diseases.

  19. Lead and cadmium in red deer and wild boar from different hunting grounds in Croatia

    The concentration and relations of Cd and Pb as environmental risk factors were studied by atomic absorption spectrophotometry in the liver, kidney and muscle of free ranging wild boar (n = 94) and red deer (n = 45) from hunting grounds in four counties of north-east Croatia. In all four counties, the levels of Cd found in the kidney of red deer ranged from 2.28 to 5.91 mg/kg, and in wild boar from 3.47 to 21.10 mg/kg. The mean renal concentration of Cd was significantly higher in wild boar than in red deer from all four study areas. The mean hepatic (0.11 to 0.49 mg/kg, respectively) and muscle (0.01 to 0.04 mg/kg, respectively) Cd concentrations were similar in both species. The mean renal Cd concentration in wild boar and red deer exceeded 1 mg/kg in all four counties, ranging from 67.0% to 91.4% and from 45.5% to 69.2%, respectively. Also, the hepatic Cd/renal Cd ratio was lower than 1 in all animals. In all four counties, renal Pb concentration ranged from 0.058 to 3.77 mg/kg in red deer and from 0.056 to 11.60 mg/kg in wild boar. Hepatic Pb concentration was similar in both species (0.061 to 0.202 mg/kg in wild boar and 0.077 to 0.108 mg/kg in red deer). Because of the high Cd level in the organs of wild boar and red deer, further research is needed to identify the source of contamination in order to preserve the health of animals and humans.

  20. The dynamics of endemic malaria in populations of varying size

    A mathematical model for endemic malaria involving variable human and mosquito populations is analysed. A threshold parameter R0 exists and the disease can persist if and only if R0 exceeds 1. R0 is seen to be a generalisation of the basic reproduction ratio associated with the Ross-Macdonald model for malaria transmission. The disease free equilibrium always exist and is globally stable when R0 is below 1. A perturbation analysis is used to approximate the endemic equilibrium in the important case where the disease related death rate is nonzero. A diffusion approximation is used to approximate the quasi-stationary distribution of the associated stochastic model. Numerical simulations show that when R0 is distinctly greater than 1, the endemic deterministic equilibrium is globally stable. Furthermore, in quasi-stationarity, the stochastic process undergoes oscillations about a mean population whose size can be approximated by the stable endemic deterministic equilibrium. (author)

  1. Spatial distribution of Madeira Island Laurisilva endemic spiders (Arachnida: Araneae

    Luís Crespo

    2014-02-01

    Full Text Available Madeira island presents a unique spider diversity with a high number of endemic species, many of which are still poorly known. A recent biodiversity survey on the terrestrial arthropods of the native forest, Laurisilva, provided a large set of standardized samples from various patches throughout the island. Out of the fifty two species recorded, approximately 33.3% are Madeiran endemics, many of which had not been collected since their original description. Two new species to science are reported – Ceratinopsis n. sp. and Theridion n. sp. – and the first records of Poeciloneta variegata (Blackwall, 1841 and Tetragnatha intermedia Kulczynski, 1891 are reported for the first time for Madeira island. Considerations on species richness and abundance from different Laurisilva locations are presented, together with distribution maps for endemic species. These results contribute to a better understanding of spider diversity patterns and endemic species distribution in the native forest of Madeira island.

    1996-09-01

    Several issues dominated the 36th Red Deer Seminar of the propane industry, among them changes to the Alberta fuel tax collection system, propane and automobile emissions and industry self-management. With regard to changes to the Alberta fuel tax collection system, details were provided on how the system, coming into effect on January 1, 1997, will impact on producers, distributors and retailers. In terms of automobile emissions, it was said that propane has lagged behind gasoline in technological development, hence propane no longer has advantages in emissions. It was noted, however, that with equivalent technology propane can still meet ultra-low emission standards. Regarding industry self-management, it was stressed that self-management did not mean deregulation since government retains policy, regulation and standard setting. It means a new partnership arrangement in which industry delivers services formerly provided by government. In this spirit of cooperation, it was announced that effective September 1996, administration of the auto propane vehicle conversion program will be transferred to the PGAC under the name of Alberta Propane Vehicle Administration Organization. 3 figs.

    2004-10-01

    We examined the geographical variation of the skull size and shape of the lesser mouse deer (Tragulus javanicus) from Laos, Thailand, Peninsular Malaysia, Sumatra, Java, Borneo, Langkawi and some Islands of Tenasserim in Myanmar. Although the influence of the climatic condition on skull size was not confirmed in the mainland populations, the skull became rostro-caudally longer in the populations of Tenasserim and Sumatra because of island isolation effect. The skull size was classified into the following three clusters of localities from the matrix of Q-mode correlation coefficients: 1) Langkawi and Tenasserim, 2) Laos and Thailand, 3) Sumatra and Borneo. The skulls in the population of Java belong to the cluster of Langkawi and Tenasserim in male, however were morphologically similar to those in the cluster of Borneo and Sumatra. The canonical discriminant analysis pointed out that the Laos and Tenasserim populations were separated from the other ones and that the populations of Sumatra, Java and Borneo were intermingled each other.

  6. Intracerebral Malignant Plasmacytoma in a Mule Deer (Odocoileus hemionus).

    Clancy, C S; Roug, A; Armien, A G; Van Wettere, A J

    2016-01-01

    A wild, mature, gravid female mule deer (Odocoileus hemionus) was presented with marked neurological signs, including abnormal behaviour, circling and incoordination. The animal was humanely destroyed and submitted for diagnostic investigation. Grossly, a well-demarcated, 3 × 3 × 3 cm intracranial mass replaced the left olfactory bulb and frontal lobe. Histologically, there was a highly cellular, infiltrative and unencapsulated neoplastic mass of round cells with eccentrically located nuclei. Neoplastic cells were immunohistochemically labelled for lambda immunoglobulin light chain. Clusters of CD20- and CD79a-positive cells were scattered throughout the tumour and CD3- and Iba1-positive cells diffusely infiltrated the neoplasm. Ultrastructurally, the cytoplasm of the neoplastic cells had prominent rough endoplasmic reticulum with a variable degree of dilation. Histopathological, immunohistochemical and electron microscopical results were diagnostic for a solitary extramedullary plasmacytoma. Intracranial neoplasms are rarely diagnosed in wildlife species, but they should be included in the differential diagnosis for potential causes of central nervous system disease. PMID:26987510

  7. A world malaria map: Plasmodium falciparum endemicity in 2007.

    2009-03-01

    Full Text Available BACKGROUND: Efficient allocation of resources to intervene against malaria requires a detailed understanding of the contemporary spatial distribution of malaria risk. It is exactly 40 y since the last global map of malaria endemicity was published. This paper describes the generation of a new world map of Plasmodium falciparum malaria endemicity for the year 2007. METHODS AND FINDINGS: A total of 8,938 P. falciparum parasite rate (PfPR surveys were identified using a variety of exhaustive search strategies. Of these, 7,953 passed strict data fidelity tests for inclusion into a global database of PfPR data, age-standardized to 2-10 y for endemicity mapping. A model-based geostatistical procedure was used to create a continuous surface of malaria endemicity within previously defined stable spatial limits of P. falciparum transmission. These procedures were implemented within a Bayesian statistical framework so that the uncertainty of these predictions could be evaluated robustly. The uncertainty was expressed as the probability of predicting correctly one of three endemicity classes; previously stratified to be an informative guide for malaria control. Population at risk estimates, adjusted for the transmission modifying effects of urbanization in Africa, were then derived with reference to human population surfaces in 2007. Of the 1.38 billion people at risk of stable P. falciparum malaria, 0.69 billion were found in Central and South East Asia (CSE Asia, 0.66 billion in Africa, Yemen, and Saudi Arabia (Africa+, and 0.04 billion in the Americas. All those exposed to stable risk in the Americas were in the lowest endemicity class (PfPR2-10 5 to or = 40% areas. High endemicity was widespread in the Africa+ region, where 0.35 billion people are at this level of risk. Most of the rest live at intermediate risk (0.20 billion, with a smaller number (0.11 billion at low stable risk. CONCLUSIONS: High levels of P. falciparum malaria endemicity are common

  12. Bird pollination of Canary Island endemic plants

    Ollerton, Jeff; Cranmer, Louise; Stelzer, Ralph J.; Sullivan, Steve; Chittka, Lars

    2009-02-01

    The Canary Islands are home to a guild of endemic, threatened bird-pollinated plants. Previous work has suggested that these plants evolved floral traits as adaptations to pollination by flower specialist sunbirds, but subsequently, they appear to have co-opted generalist passerine birds as sub-optimal pollinators. To test this idea, we carried out a quantitative study of the pollination biology of three of the bird-pollinated plants, Canarina canariensis (Campanulaceae), Isoplexis canariensis (Veronicaceae) and Lotus berthelotii (Fabaceae), on the island of Tenerife. Using colour vision models, we predicted the detectability of flowers to bird and bee pollinators. We measured pollinator visitation rates, nectar standing crops as well as seed-set and pollen removal and deposition. These data showed that the plants are effectively pollinated by non-flower specialist passerine birds that only occasionally visit flowers. The large nectar standing crops and extended flower longevities (>10 days) of Canarina and Isoplexis suggests that they have evolved a bird pollination system that effectively exploits these low frequency non-specialist pollen vectors and is in no way sub-optimal. Seed set in two of the three species was high and was significantly reduced or zero in flowers where pollinator access was restricted. In L. berthelotii, however, no fruit set was observed, probably because the plants were self-incompatible horticultural clones of a single genet. We also show that, while all three species are easily detectable for birds, the orange Canarina and the red Lotus (but less so the yellow-orange Isoplexis) should be difficult to detect for insect pollinators without specialised red receptors, such as bumblebees. Contrary to expectations if we accept that the flowers are primarily adapted to sunbird pollination, the chiffchaff ( Phylloscopus canariensis) was an effective pollinator of these species.

  13. Endemic pemphigus over a century: Part II

    Ana María Abréu-Vélez

    2010-03-01

    Full Text Available Background: Endemic pemphigus foliaceus (EPF is an autoimmune disease, classically occurring in a restricted geographic area. Foci of EPF have been described in several Central and South American countries, often affecting young people and Amerindians, with some female predilection. Although most American EPF cases have been documented in Brazil, cases have been reported in Peru, Paraguay, El Salvador and Venezuela. An additional variant of EPF has been described in El Bagre, Colombia, (El Bagre-EPF affecting older men and a few post-menopausal females. Finally, one additional type of EPF has been described in nomadic tribes affecting females of child bearing age in Tunisia, Africa. Aims: The main aim of this review is to summarize current knowledge about autoantigens, and immunologic and genetic studies in EPF. Material and Methods: We utilized a retrospective review of the literature, aiming to compile and compare the multiple geographic foci of EPF. Results: The primary autoantigens in EPF are still considered to be desmogleins in the case of the Tunisian and all American cases, in contradistinction to plakins and desmogleins in El Bagre-EPF. Although several autoantigens are been suggested, their biochemical nature needs further elucidation. Current knowledge still supports the concept that an antibody mediated immune response represents the principal pathophysiology in all variants of EPF. Conclusion: A strong genetic susceptibility appears to contribute to disease development in several people affected by these diseases; however, no specific genes have been confirmed at present. We conclude that further investigation is necessary to define these disorders immunologically and genetically.

  15. Dama roberti, a new species of deer from the early Middle Pleistocene of Europe, and the origins of modern fallow deer

    Breda, Marzia; Lister, Adrian M.

    2013-06-01

    The ancestry of the modern fallow deer, Dama dama, has been tentatively traced back to Pliocene/Early Pleistocene forms referred to 'Pseudodama', characterized by unpalmated three- or four-point antlers. By the late Middle Pleistocene, Dama with palmated antlers appears, as Dama dama clactoniana. However, fallow deer from the interim period, the early Middle Pleistocene, are poorly-known. A new specimen from Pakefield (Suffolk, UK), represented by a portion of cranium with a substantial part of both antlers plus a mandible and scapula, is the most complete medium-sized deer specimen from the British early Middle Pleistocene (ca 700 ka). The position and orientation of the basal tine, together with dental characters and mandibular morphology, are typical of fallow deer. The narrow palmation is reminiscent of D. dama clactoniana, but the lack of palmation tines is unique. Moreover, the lack of second (and third) tines in an adult specimen differs from both D. dama dama and D. d. clactoniana, being a primitive character shared with the last representatives of 'Pseudodama' which, on the other hand, has a circular beam lacking any palmation. This combination of features justifies the erection of a new species provisionally placed within the genus Dama, Dama roberti n. sp. Another specimen, from Soleilhac (Auvergne, France), represented by portions of the two antlers, a mandible and a tibia, shares antler morphology with the Pakefield specimen and can be ascribed to the same new species. Isolated antler and dental remains from coeval British sites are tentatively ascribed to D. roberti n. sp. The new species has implications for the ancestry of modern fallow deer.

  16. Future of Endemic Flora of Biodiversity Hotspots in India

    Chitale, Vishwas Sudhir; Behera, Mukund Dev; Roy, Partha Sarthi

    2014-01-01

    India is one of the 12 mega biodiversity countries of the world, which represents 11% of world's flora in about 2.4% of global land mass. Approximately 28% of the total Indian flora and 33% of angiosperms occurring in India are endemic. Higher human population density in biodiversity hotspots in India puts undue pressure on these sensitive eco-regions. In the present study, we predict the future distribution of 637 endemic plant species from three biodiversity hotspots in India; Himalaya, Wes...

    2016-01-01

    The legume genus Mimosa has > 500 species, with two major centres of diversity, Brazil (c. 350 spp.) and Mexico (c. 100 spp.). In Brazil most species are nodulated by Burkholderia. Here we asked whether this is also true of native and endemic Mexican species. We have tested this apparent affinity for betaproteobacteria by examining the symbionts of native and endemic species of Mimosa in Mexico, especially from the central highlands where Mimosa spp. have diversified.

    Endemic/epidemic dengue viruses (DEN) that are transmitted among humans by the mosquito vectors Aedes aegypti and Aedes albopictus are hypothesized to have evolved from sylvatic DEN strains that are transmitted among nonhuman primates in West Africa and Malaysia by other Aedes mosquitoes. We tested this hypothesis with phylogenetic studies using envelope protein gene sequences of both endemic/epidemic and sylvatic strains. The basal position of sylvatic lineages of DEN-1, -2, and -4 suggested...

    2008-01-01

    Summary The quantification of malaria transmission for the classification of malaria risk has long been a concern for epidemiologists. During the era of the Global Malaria Eradication Programme, measurements of malaria endemicity were institutionalised by their incorporation into rules outlining defined action points for malaria control programmes. We review the historical development of these indices and their contemporary relevance. This is at a time when many malaria-endemic countries are ...

  20. Malaria seroprevalence in blood bank donors from endemic and non-endemic areas of Venezuela

    2011-03-01

    Full Text Available In Venezuela, a total of 363,466 malaria cases were reported between 1999-2009. Several states are experiencing malaria epidemics, increasing the risk of vector and possibly transfusion transmission. We investigated the risk of transfusion transmission in blood banks from endemic and non-endemic areas of Venezuela by examining blood donations for evidence of malaria infection. For this, commercial kits were used to detect both malaria-specific antibodies (all species and malaria antigen (Plasmodium falciparum only in samples from Venezuelan blood donors (n = 762. All samples were further studied by microscopy and polymerase chain reaction (PCR. The antibody results showed that P. falciparum-infected patients had a lower sample/cut-off ratio than Plasmodium vivax-infected patients. Conversely, a higher ratio for antigen was observed among all P. falciparum-infected individuals. Sensitivity and specificity were higher for malarial antigens (100 and 99.8% than for antibodies (82.2 and 97.4%. Antibody-positive donors were observed in Caracas, Ciudad Bolívar, Puerto Ayacucho and Cumaná, with prevalences of 1.02, 1.60, 3.23 and 3.63%, respectively. No PCR-positive samples were observed among the donors. However, our results show significant levels of seropositivity in blood donors, suggesting that more effective measures are required to ensure that transfusion transmission does not occur.

    Oceanic islands are of fundamental importance for the conservation of biodiversity because they exhibit high endemism rates coupled with fast extinction rates. Nowhere in Europe is this pattern more conspicuous than in the Macaronesian biogeographic region. A large network of protected areas within the region has been developed, but the question of whether these areas will still be climatically suitable for the globally threatened endemic element in the coming decades remains open. Here, we make predictions on the fate of the Macaronesian endemic bryophyte flora in the context of ongoing climate change. The potential distribution of 35 Macaronesian endemic bryophyte species was assessed under present and future climate conditions using an ensemble modelling approach. Projections of the models under different climate change scenarios predicted an average decrease of suitable areas of 62-87% per species and a significant elevational increase by 2070, so that even the commonest species were predicted to fit either the Vulnerable or Endangered IUCN categories. Complete extinctions were foreseen for six of the studied Macaronesian endemic species. Given the uncertainty regarding the capacity of endemic species to track areas of suitable climate within and outside the islands, active management associated to an effective monitoring program is suggested.

  3. Is Sustainablity Possible in Protected Areas in Mexico? Deer as an Example of a Renewable Resource

    2012-09-01

    Full Text Available In 2000, Mexico’s National Commission of Protected Areas (CONANP was created to encourage the protection, management and restoration of natural and cultural resources and their conservation. Protected areas were recently increased by more than 3 million hectares, for a current total of more than 25 million hectares, corresponding to 174 protected areas that cover 12.90% of the country’s surface area. The information obtained by research helps us understand both biodiversity and ecological processes, as well as the social and economic phenomena that influence the use of ecosystems. In Mexico there are four species of deer: white-tailed deer, mule deer, red brocket and brown brocket. These ungulates have been an important part of the diet of indigenous people and rural communities, and represent an important resource for sport and trophy hunting. We found the best deer populations in protected areas; these can therefore maintain the gene pool and serve as source populations for other areas. These populations are also useful from a research perspective. People living in some protected areas continue to use natural resources such as deer, and also receive economic inputs to develop ecotourism programs, and support from the government for the environmental services derived from conserving biodiversity.

  4. Determinants of vigilance in a reintroduced population of Père David's deer

    2013-04-01

    Full Text Available After being kept in captivity and isolated from natural predators for more than 1,200 years, Père David’s deer has been reintroduced in China and now occurs in a reserve where human activity is the only potential threat. Antipredator vigilance is an important component of survival for many prey animals in their natural habitat. Do deer still adjust vigilance as a function of risk after such a long period of relaxed predation pressure? Here, we examined vigilance levels in Père David’s deer groups as a function of group size, sex and level of human disturbance. The results showed that individual vigilance significantly decreased with group size in all-female groups but not in all-males or mixed-sex groups. In rutting season, males compete with one another and harass females, and we argue that vigilance is partly aimed at threatening males and that such vigilance increases with group size. This explains why overall vigilance did not vary with group size for males in general and for females in mixed-sex groups. Vigilance increased in more disturbed areas but in in male deer only. The results indicate that despite relaxed predation pressure over centuries, Père David’s deer can still adjust antipredator responses as a function of perceived risk. Such information may become useful in the rewilding programme now under way for this species in China [Current Zoology 59 (2: 265–270, 2013].

  6. Complement-mediated killing of Borrelia burgdorferi by nonimmune sera from sika deer.

    Nelson, D R; Rooney, S; Miller, N J; Mather, T N

    2000-12-01

    Various species of cervid deer are the preferred hosts for adult, black-legged ticks (Ixodes scapularis and Ixodes pacificus) in the United States. Although frequently exposed to the agent of Lyme disease (Borrelia burgdorferi), these animals, for the most part, are incompetent as transmission reservoirs. We examined the borreliacidal activity of normal and B. burgdorferi-immune sera from sika deer (Cervus nippon) maintained in a laboratory setting and compared it to that of similar sera from reservoir-competent mice and rabbits. All normal deer sera (NDS) tested killed > 90% of B. burgdorferi cells. In contrast, normal mouse and rabbit sera killed 1:1,024. Heat treatment (56 C, 30 min) of NDS reduced borreliacidal activity, with 90% of the cells killed. Addition of 10 mM EDTA reduced the killing to approximately 30%, whereas the addition of Mg2+ (10 mM) restored borreliacidal activity to NDS. The addition of zymosan A, an activator of the alternative pathway, increased the survival of B. burgdorferi cells to approximately 80% in NDS. These data suggest that the alternative complement activation pathway plays a major role in the borreliacidal activity of NDS. Additionally, 10 mM EGTA had almost no effect on the killing activity of B. burgdorferi-exposed deer sera, suggesting that the classical pathway is not involved in Borrelia killing, even in sera from B. burgdorferi-exposed deer.

  7. Tuberculosis, genetic diversity and fitness in the red deer, Cervus elaphus.

    2016-09-01

    Understanding how genetic diversity, infections and fitness interact in wild populations is a major challenge in ecology and management. These interactions were addressed through heterozygosity-fitness correlation analyses, by assessing the genetic diversity, tuberculosis (TB) and body size in adult red deer. Heterozygosity-fitness correlation models provided a better understanding of the link between genetic diversity and TB at individual and population levels. A single local effect was found for Ceh45 locus at individual level, enhancing the importance of its close functional genes in determining TB presence. At population level, the ability of the red deer to control TB progression correlated positively with population genetic diversity, indicating that inbred populations might represent more risk of deer TB severity. Statistical models also gained insights into the dynamics of multi-host interaction in natural environments. TB prevalence in neighbouring wild boar populations was positively associated with deer TB at both individual and population levels. Additionally, TB presence correlated positively with red deer body size, for which "general and local effect" hypotheses were found. Although body size might be correlated with age, an indirect genetic effect on TB presence could be implied. This study provides new insights towards understanding host-pathogen interactions in wild populations and their relation to fitness traits. PMID:27245150

    1975-10-01

    Serums from 4 species of deer and 1 species of antelope were analyzed for various components in order to define an animal disease model for sickle cell disease in people. Animal species included black-tailed deer (Odocoileus hemionus columbianus), mule deer (Odocoileus hemionus), sika deer (Cervus nippon nippon), fallow deer (Dama dama), and pronghorn antelope (Antilocapra americana). The mean serum values for total bilirubin, total protein, albumin, creatinine, urea nitrogen, and electrolytes were similar in all species and were in the normal range for human beings. Cholesterol and uric acid values for all animals were lower than those for people. Alkaline phosphatase values in the 4 cervid species were higher than in the pronghorn antelope. Values for glutamic oxalacetic transaminase were lower in the cervids than in the pronghorn antelope. Lactic dehydrogenase values were similar in the 5 species. High activities for glutamic oxalacetic transaminase and lactic dehydrogenase in the 5 species probably related to muscle mass and great muscular activity. PMID:1190586

  9. Fine-scale genetic structure and social organization in female white-tailed deer.

    Comer, Christopher E.; Kilgo, John C.; D' Angelo, Gino J.; Glenn, Travis C.; Miller, Karl V.

    2005-07-01

    Abstract: Social behavior of white-tailed deer (Odocoileus virginianus) can have important management implications. The formation of matrilineal social groups among female deer has been documented and management strategies have been proposed based on this well-developed social structure. Using radiocollared (n = 17) and hunter or vehicle-killed (n = 21) does, we examined spatial and genetic structure in white-tailed deer on a 7,000-ha portion of the Savannah River Site in the upper Coastal Plain of South Carolina, USA. We used 14 microsatellite DNA loci to calculate pairwise relatedness among individual deer and to assign doe pairs to putative relationship categories. Linear distance and genetic relatedness were weakly correlated (r = –0.08, P = 0.058). Relationship categories differed in mean spatial distance, but only 60% of first-degree-related doe pairs (full sibling or mother–offspring pairs) and 38% of second-degree-related doe pairs (half sibling, grandmother–granddaughter pairs) were members of the same social group based on spatial association. Heavy hunting pressure in this population has created a young age structure among does, where the average age is <2.5 years, and <4% of does are >4.5 years old. This—combined with potentially elevated dispersal among young does—could limit the formation of persistent, cohesive social groups. Our results question the universal applicability of recently proposed models of spatial and genetic structuring in white-tailed deer, particularly in areas with differing harvest histories.

  10. Measuring Fine-Scale White-Tailed Deer Movements and Environmental Influences Using GPS Collars

    Few studies have documented fine-scale movements of ungulate species, including white-tailed deer (Odocoileus virginianus), despite the advent of global positioning system (GPS) technology incorporated into tracking devices. We collected fine-scale temporal location estimates (i.e., 15 min/relocation attempt) from 17 female and 15 male white-tailed deer over 7 years and 3 seasons in Oklahoma, USA. Our objectives were to document fine-scale movements of females and males and determine effects of reproductive phase, moon phase, and short-term weather patterns on movements. Female and male movements were primarily crepuscular. Male total daily movements were 20% greater during rut (7,363? 364) than postrut (6,156 m±260). Female daily movements were greatest during post parturition (3,357 91), followed by parturition (2,902 m±107), and pre parturition (2,682 m±121). We found moon phase had no effect on daily, nocturnal, and diurnal deer movements and fine-scale temporal weather conditions had an inconsistent influence on deer movement patterns within season. Our data suggest that hourly and daily variation in weather events have minimal impact on movements of white-tailed deer in southern latitudes. Instead, routine crepuscular movements, presumed to maximize thermoregulation and minimize predation risk, appear to be the most important factors influencing movements.

    The objective of the present study was to investigate the prevalence and genetic characterization of Toxoplasma gondii infection in sika deer in China. During August 2014 to November 2014, a total of 450 tissue samples coming from 150 sika deer were collected to detect the T. gondii B1 gene using a nested PCR, and the positive samples were genotyped at 11 genetic markers (SAG1, 5'- and 3'-SAG2, alternative SAG2, SAG3, BTUB, GRA6, L358, PK1, c22-8, c29-2, and Apico) using multilocus polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technology. Seventeen of 150 sika deer (11.33%) were tested positive by nested PCR. Six DNA samples from the 17 positive samples were completely typed, in which 4 samples from lung tissues, and 2 from muscular tissues, were identified as ToxoDB Genotype #9 (http://toxodb.org/toxo/). The results of the present study revealed the existence of T. gondii infection in sika deer in China, which provided the information of T. gondii genetic diversity in this host species. This study also indicated that ToxoDB Genotype #9 has a wide distribution in sika deer that could be potential reservoirs for T. gondii transmission, which may pose a threat to human health.

  12. Effects of supplemental dietary tannins on the performance of white-tailed deer (Odocoileus virginianus).

    Chapman, G A; Bork, E W; Donkor, N T; Hudson, R J

    2010-02-01

    Tannins are natural and nutritionally significant components of the diets of browsing ungulates. In trials on supplemented pastures and in drylots, we estimated dry matter intake (DMI), weight gain, and urea N, potassium, cortisol and creatinine in urine of captive white-tailed deer fed pelleted diets that differed only in the respective quebracho tannin (QT) content. The low control, medium and high QT rations were 3.6, 63 and 152 g/kg DM respectively. There was no tannin-free pellet option. Trials were divided into winter pasture, restricted choice and spring growth. In winter pasture trial on pasture using QT, deer reduced QT intake relative to that expected under random foraging. This aversion was also apparent during the spring growth trial. While DMI in the winter pasture trial remained similar among treatments (p > 0.05), averaging 130 g/kg(0.75)/day, deer gained more weight (p 0.05). Collectively, these results suggest that although deer do not avoid tannins, and even ingested up to 5% under the choice options in these trials, the effect of tannins on deer performance may vary by season as well as by foraging opportunities.

  13. Iodine-129 in forage and deer on the Hanford site and other Pacific Northwest locations

    Samples of surface soil, litter, forage, and deer (rumen content, muscle, liver, and thyroid gland) were collected from Bend, Oregon; Centralia, Washington; Wenatchee, Washington; the Wooten Game Range near Dayton, Washington; and on or near the Hanford Site, Richland, Washington. The concentrations of 129I and 127I were determined using neturon activation techniques. The purpose of the study was to establish the current levels of 129I in the environs of the Hanford Site prior to the proposed restart of fuel reprocessing at the PUREX plant. The results of this study clearly demonstrated the longevity of 129I in the biosphere following gaseous release from a nuclear facility. Analyses of thyroid glands showed that deer living within 160 km (Wooten Game Range) of Hanford had elevated levels of 129I when compared to the more distant Pacific Northwest locations (Centralia, or Bend). Levels of 129I in deer thyroid from Bend, or Centralia, (15 fCi/g wet weight), were about five times higher than values reported for the central United States, while, Hanford samples were about 2,700 times higher. The average concentration of 129I in deer thyroids collected at Hanford in 1978 was similar to samples collected 14 years earlier. The concentrations of 129I in soil, litter, forage, and other deer samples generally decrease in the order: Hanford > Wooten > Wenatchee > Centralia approx. = Bend. This corresponds to an increase in distance from the Hanford Site

    Large herbivores and deer in particular can have dramatic effects on ecosystem functions and act as keystone species in many forest systems. At high densities, deer are assumed to determine the structure and composition of forest understory. The introduction in the late 19th century of the Sitka black-tailed deer (Odocoileus hemionus sitkensis) on Haïda Gwaii archipelago (British Columbia, Canada) gave us the opportunity to illustrate the effects of predator-free deer populations on previousl...

  17. Candidate adaptive genes associated with lineage divergence: identifying SNPs via next-generation targeted resequencing in mule deer (Odocoileus hemionus).

    Powell, John H; Amish, Stephen J; Haynes, Gwilym D; Luikart, Gordon; Latch, Emily K

    2016-09-01

    Mule deer (Odocoileus hemionus) are an excellent nonmodel species for empirically testing hypotheses in landscape and population genomics due to their large population sizes (low genetic drift), relatively continuous distribution, diversity of occupied habitats and phenotypic variation. Because few genomic resources are currently available for this species, we used exon data from a cattle (Bos taurus) reference genome to direct targeted resequencing of 5935 genes in mule deer. We sequenced approximately 3.75 Mbp at minimum 20X coverage in each of the seven mule deer, identifying 23 204 single nucleotide polymorphisms (SNPs) within, or adjacent to, 6886 exons in 3559 genes. We found 91 SNP loci (from 69 genes) with putatively fixed allele frequency differences between the two major lineages of mule deer (mule deer and black-tailed deer), and our estimate of mean genetic divergence (genome-wide FST  = 0.123) between these lineages was consistent with previous findings using microsatellite loci. We detected an over-representation of gamete generation and amino acid transport genes among the genes with SNPs exhibiting potentially fixed allele frequency differences between lineages. This targeted resequencing approach using exon capture techniques has identified a suite of loci that can be used in future research to investigate the genomic basis of adaptation and differentiation between black-tailed deer and mule deer. This study also highlights techniques (and an exon capture array) that will facilitate population genomic research in other cervids and nonmodel organisms. PMID:27438092

    A single Gray Wolf (Canis lupus) killed an adult male White-tailed Deer (Odocoileus virginianus) and cached the intact carcass in 76 cm of snow. The carcass was revisited and entirely consumed between four and seven days later. This is the first recorded observation of a Gray Wolf caching an entire adult deer.

  1. Diversity of rickettsial pathogens in Columbian black-tailed deer and their associated keds (Diptera: Hippoboscidae) and ticks (Acari: Ixodidae).

    Foley, Janet E; Hasty, Jeomhee M; Lane, Robert S

    2016-06-01

    Cervids host multiple species of ixodid ticks, other ectoparasites, and a variety of rickettsiae. However, diagnostic test cross-reactivity has precluded understanding the specific role of deer in rickettsial ecology. In our survey of 128 Columbian black-tailed deer (Odocoileus hemionus columbianus (Richardson)) and their arthropod parasites from two northern Californian herds, combined with reports from the literature, we identified four distinct Anaplasma spp. and one Ehrlichia species. Two keds, Lipoptena depressa (Say) and Neolipoptena ferrisi Bequaert, and two ixodid ticks, Ixodes pacificus Cooley and Kohls and Dermacentor occidentalis Marx, were removed from deer. One D. occidentalis was PCR-positive for E. chaffeensis; because it was also PCR-positive for Anaplasma sp., this is an Anaplasma/Ehrlichia co-infection prevalence of 4.3%. 29% of L. depressa, 23% of D. occidentalis, and 14% of deer were PCR-positive for Anaplasma spp. DNA sequencing confirmed A. bovis and A. ovis infections in D. occidentalis, A. odocoilei in deer and keds, and Anaplasma phagocytophilum strain WI-1 in keds and deer. This is the first report of Anaplasma spp. in a North America deer ked, and begs the question whether L. depressa may be a competent vector of Anaplasma spp. or merely acquire such bacteria while feeding on rickettsemic deer.

  3. Natural and experimental tests of trophic cascades: gray wolves and white-tailed deer in a Great Lakes forest.

    Flagel, D G; Belovsky, G E; Beyer, D E

    2016-04-01

    Herbivores can be major drivers of environmental change, altering plant community structure and changing biodiversity through the amount and species of plants consumed. If natural predators can reduce herbivore numbers and/or alter herbivore foraging behavior, then predators may reduce herbivory on sensitive plants, and a trophic cascade will emerge. We have investigated whether gray wolves (Canis lupus) generate such trophic cascades by reducing white-tailed deer (Odocoileus virginianus) herbivory on saplings and rare forbs in a northern mesic forest (Land O' Lakes, WI). Our investigation used an experimental system of deer exclosures in areas of high and low wolf use that allowed us to examine the role that wolf predation may play in reducing deer herbivory through direct reduction in deer numbers or indirectly through changing deer behavior. We found that in areas of high wolf use, deer were 62 % less dense, visit duration was reduced by 82 %, and percentage of time spent foraging was reduced by 43 %; in addition, the proportion of saplings browsed was nearly sevenfold less. Average maple (Acer spp.) sapling height and forb species richness increased 137 and 117 % in areas of high versus low wolf use, respectively. The results of the exclosure experiments revealed that the negative impacts of deer on sapling growth and forb species richness became negligible in high wolf use areas. We conclude that wolves are likely generating trophic cascades which benefit maples and rare forbs through trait-mediated effects on deer herbivory, not through direct predation kills. PMID:26670677

  4. Co-phylogeography and morphological evolution of sika deer lice (Damalinia sika) with their hosts (Cervus nippon).

    Mizukoshi, Atsushi; Johnson, Kevin P; Yoshizawa, Kazunori

    2012-10-01

    Lice are obligate parasites of mammals and birds and have become an important model for studies of host-parasite co-evolution and co-phylogenetics. Population genetic and phylogeographic studies represent an important bridge between microevolution and co-phylogenetic patterns. We examine co-phylogeographic patterns in sika deer and their parasitic lice. Co-phylogeographic patterns in deer and lice were evaluated using homologous regions of mitochondrial COI sequences. The phylogeographic breaks recovered for deer populations matched those of previous studies. Comparisons of the phylogeographic tree topology for deer lice with that of their hosts revealed a significant level of congruence. However, comparisons of genetic distances between deer and lice suggested that one of the estimated co-divergence events is more likely a recent host switch. Taking into account genetic divergence, there is not strong evidence for complete phylogeographic co-divergence between deer and their parasitic lice. However, mitochondrial phylogenies only track genetic structure of female lineages, and the incongruence between deer and louse phylogeography may be explained by louse migration mediated by male deer. Morphological analysis of head shape variation based on an elliptic Fourier descriptor showed that overall morphological variation contained phylogenetic signal, suggesting that in general morphology of these lice evolves congruent to population history.

  5. Pattern and Drivers of White-Tailed Deer (Odocoileus virginianus Herbivory on Tree Saplings across a Plateau Landscape

    Jonathan P. Evans

    2016-05-01

    Full Text Available White-tailed deer (Odocoileus virginianus populations are impacting long-term regeneration across eastern United States forests. Deer distribution and resulting herbivory patterns are variable across a landscape due to habitat patchiness and topography. It is poorly understood how features associated with topography control deer herbivory. We examined the heterogeneity of deer herbivory as it affects sapling densities across a single forest-type landscape on the Cumberland Plateau. The 1242 hectare site represented a peninsula of tableland that transitioned from developed land to forest and was surrounded on three sides by a bluff, irregularly punctuated by drainages. We examined the spatial variability of deer impacts on sapling density and modeled the relative importance of plateau accessibility features related to topography, proximity to edge, and deer culling as predictors of sapling variation. We used a stratified random design to sample sapling density across the landscape in 2012 and 2015. The intensity of deer herbivory on saplings varied, with the fewest saplings in forests surrounded by residential development. Our model predicted that plateau accessibility measures best determined sapling densities, followed by distance from edge and deer culling measures. Our results suggest that herbivory impacts may not be homogeneous in a contiguous uniform landscape if there are topographic barriers.

  6. Preventing the Establishment of a Wildlife Disease Reservoir: A Case Study of Bovine Tuberculosis in Wild Deer in Minnesota, USA

    Michelle Carstensen

    2011-01-01

    Full Text Available Bovine tuberculosis (bTB has been found in 12 cattle operations and 27 free-ranging white-tailed deer (Odocoileus virginianus in northwestern Minnesota, following the state's most recent outbreak of the disease in 2005 in the northwest part of the state. Both deer and cattle have the same strain of bTB. The Minnesota Board of Animal Health has been leading efforts to eradicate the disease in Minnesota's cattle, which have included the depopulation of all infected herds, a cattle buy-out program, and mandatory fencing of stored feeds. The Minnesota Department of Natural Resources began surveillance efforts in free-ranging white-tailed deer in fall 2005. All bTB-infected deer have been found within a 16 km2 area in direct association with infected cattle farms. Aggressive efforts to reduce deer densities through liberalized hunting and sharpshooting have resulted in a 55% decline in deer densities. Also, recreational feeding of wild deer has been banned. Disease prevalence in deer has decreased from 1.2% in 2005 to an undetectable level in 2010.

    of mammalian species that are high-altitude natives. Here we investigated genetically based differences in Hb–O2 affinity between highland and lowland populations of the deer mouse (Peromyscus maniculatus), a generalist species that has the broadest altitudinal distribution of any North American...... mammal. The results of a combined genetic and proteomic analysis revealed that deer mice harbor a high level of Hb isoform diversity that is attributable to allelic polymorphism at two tandemly duplicated -globin genes and two tandemly duplicated β-globin genes. This high level of isoHb diversity...... experiments also revealed distinct biochemical properties of deer mouse Hb related to the anion-dependent allosteric regulation of O2 affinity. In conjunction with previous findings, our results demonstrate that modifications of Hb structure that alter allosteric anion sensitivity play an important role in...

  8. Aversive responses of white-tailed deer,Odocoileus virginianus, to predator urines.

    Swihart, R K; Pignatello, J J; Mattina, M J

    1991-04-01

    We tested whether predator odors could reduce winter browsing of woody plants by white-tailed deer (Odocoileus virginianus). Urine from bobcats (Lyra rufus) and coyotes (Canis latrans) significantly reduced browsing of Japanese yews (Taxus cuspidata), and repellency was enhanced when urine was reapplied weekly as a topical spray. Urine of cottontail rabbits (Sylvilagus floridanus) and humans did not reduce damage, suggesting that deer do not respond aversively to odors of nonpredatory mammals or occasional predators with which they lack a long evolutionary association. Bobcat and coyote urine were more effective in tests conducted with eastern hemlock (Tsuga canadensis), which is less palatable to white-tailed deer than Japanese yew. A dichloromethane extract of bobcat urine was as effective as unextracted urine in reducing damage to hemlocks. Testing of the organic components of bobcat urine, particularly the volatile components, may enable identification of the compounds responsible for the repellency we observed. PMID:24258921

    2007-01-01

    We examined 976 sika deer serum samples, 159 liver tissue samples and 88 stool samples collected from 16 prefectures in Japan, and performed ELISA and RT-PCR assays to detect antibodies to HEV and HEV RNA, respectively. Although 25 (2.6%) of 976 samples were positive for anti-HEV IgG, the antibody titers were very low. The OD values ranged between 0.018 and 0.486, forming a single distribution rather than a bimodal distribution, suggesting that the antibody detected in this study was not induced by HEV infection, or that deer have low sensitivity to HEV. HEV RNA was not detected in these samples, also suggesting that deer may not play a role as an HEV reservoir. PMID:17431737

  10. Some preliminary studies of the metabolism of 99Mo-labelled compounds in deer

    The metabolism of (99Mo) compounds in plasma was followed after intravenous injection of (99Mo) trithiomolybdate and intraruminal infusion of (99Mo) molybdate in one red deer and one sika deer. Clearance of (99Mo) trithiomolybdate was rapid and residual radioactivity was (99Mo) dithiomolybdate. After ruminal infusion of (99Mo) molybdate, the main plasma (99Mo) thiomolybdate detected was also (99Mo) dithiomolybdate. These preliminary studies may provide an explanation of the apparent insensitivity of the deer to high dietary Mo, since dithiomolybdate is less likely to be toxic systemically than trithiomolybdate to tetrathiomolybdate. However, further studies with more animals and over a wider range of conditions would be advisable before definitive conclusions are drawn. (author)

    2016-08-01

    Full Text Available Aim: This study was planned to study the genotypes of verocytotoxigenic Escherichia coli (VTEC in fecal samples of deer due to its public health significance. Materials and Methods: A total of 160 fecal samples of deer were taken from Mathura district and Kanpur Zoo and screened for VTEC genes by polymerase chain reaction (PCR. Results: All fecal samples were positive for E. coli. All the E. coli isolates were screened by PCR to detect virulence genes stx1, stx2, eaeA, and hlyA. Of these, 15 isolates were found positive for VTEC having one or more genes in different combinations. Conclusion: Genes such as stx1, stx2, eaeA, and hlyA were prevalent in VTEC isolates from feces of deer. The presence of VTEC isolates having virulent genes may pose a threat to public health.

    2015-12-01

    Full Text Available This case report describes the necropsy findings of two potentially zoonotic parasites infecting the Philippine brown deer (Cervus mariannus in Leyte Island, Philippines. A female deer aging approximately 5-year was presented for necropsy to the Diagnostic Laboratory at the College of Veterinary Medicine, Visayas State University. Gross pathology was recorded and the selected organs having lesion were collected for histopathological studies. Results showed severe necrotizing lesions in the nasal and palatal areas, infestation of calliphorid maggots, hepatic fibrosis, cholangitis, cholecystitis, lung atelectasis and duodenitis. Heavy ruminal fluke infection was also observed. Two potentially zoonotic parasites namely Fasciola gigantica and Sarcocystis spp. were identified. The Philippine brown deer appears to have a role in transmission and amplification of zoonotic parasites, and can also be threatened by diseases caused by the parasites.

    2011-12-01

    Full Text Available Deer (Cervidaei belong to the most important species used as farmed animals. We focused on assesing the genetic diversity among five deer populations. Analysis has been performed on a total of 183 animals originating from Czech Republic, Hungary, New Zealand, Poland and Slovak Republic. Genetic variability were investigated using 8 microsatellite markers used in deer. Statistical data of all populations we obtained on the basis of Nei statistics, using by POWERMARKER 3.23 programme. Graphical view of relationships among populations and individuals in the populations was obtained using the Dendroscope software. Molecular genetic data combinated with evaluation in statistical programmes could lead to a complex view of populations and diffrences among them.doi:10.5219/172

  14. Serum biochemical values of rusa deer (Cervus timorensis russa) in New Caledonia.

    Audigé, L

    1992-11-01

    Blood samples were collected from 91 rusa deer (Cervus timorensis russa), immediately after being shot. Serum mean biochemical values from shot deer are presented for blood urea nitrogen, creatinine, creatine kinase, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total bilirubin, total protein, albumin, calcium, and phosphorus. Mean total protein and albumin increased with age. There was an age-associated increase of gamma globulins. Mean creatine kinase activity and creatinine, albumin and phosphorus concentrations were higher in stags than in hinds. Pregnant hinds had lower mean creatine kinase activity and phosphorus and higher mean alanine aminotransferase and total protein than non-pregnant hinds. Mean calcium concentration increased when deer were agitated before bleeding. PMID:1288472

  15. Molybdenum and copper levels in white-tailed deer near uranium mines in Texas

    King, K.A.; LeLeux, J.; Mulhern, B.M.

    1984-01-01

    Molybdenum toxicity, molybdenosis, in ruminant animals has been identified in at least 15 states and in Canada, England, Australia, and New Zealand. In most western states, molybdenosis has been associated with strip-mine spoil deposits. Molybdenum toxicity has been diagnosed in cattle pastured near uranium strip-mine spoils in several Texas counties. Recent reports from hunters and the authors' observations indicated that white-tailed deer (Odocoileus virginianus ) that fed near uranium-mine spoil deposits may also have been exposed to high levels of molybdenum. The objectives of this study were to determine if white-tailed deer from a South Texas uranium mining district were accumulating harmful levels of molybdenum and to compare molybdenum and copper levels with antler development in deer from the mined area vs. an unmined control area.

    Background Efficient allocation of resources to intervene against malaria requires a detailed understanding of the contemporary spatial distribution of malaria risk. It is exactly 40 y since the last global map of malaria endemicity was published. This paper describes the generation of a new world map of Plasmodium falciparum malaria endemicity for the year 2007. Methods and Findings A total of 8,938 P. falciparum parasite rate (PfPR) surveys were identified using a variety of exhaustive search strategies. Of these, 7,953 passed strict data fidelity tests for inclusion into a global database of PfPR data, age-standardized to 2–10 y for endemicity mapping. A model-based geostatistical procedure was used to create a continuous surface of malaria endemicity within previously defined stable spatial limits of P. falciparum transmission. These procedures were implemented within a Bayesian statistical framework so that the uncertainty of these predictions could be evaluated robustly. The uncertainty was expressed as the probability of predicting correctly one of three endemicity classes; previously stratified to be an informative guide for malaria control. Population at risk estimates, adjusted for the transmission modifying effects of urbanization in Africa, were then derived with reference to human population surfaces in 2007. Of the 1.38 billion people at risk of stable P. falciparum malaria, 0.69 billion were found in Central and South East Asia (CSE Asia), 0.66 billion in Africa, Yemen, and Saudi Arabia (Africa+), and 0.04 billion in the Americas. All those exposed to stable risk in the Americas were in the lowest endemicity class (PfPR2−10 ≤ 5%). The vast majority (88%) of those living under stable risk in CSE Asia were also in this low endemicity class; a small remainder (11%) were in the intermediate endemicity class (PfPR2−10 > 5 to < 40%); and the remaining fraction (1%) in high endemicity (PfPR2−10 ≥ 40%) areas. High endemicity was widespread in the

    Coyotes (Canis latrans) may affect adult and neonate white-tailed deer (Odocoileus virginianus) survival and have been implicated as a contributor to the decline of deer populations. Additionally, coyote diet composition is influenced by prey availability, season, and region. Because coyote movement and diet vary by region, local data are important to understand coyote population dynamics and their impact on prey species. In southeast Minnesota, we investigated the effect of coyotes on white-tailed deer populations by documenting movement rates, distances moved, and habitats searched by coyotes during fawning and non-fawning periods. Additionally, we determined survival, cause-specific mortality, and seasonal diet composition of coyotes. From 2001 to 2003, we captured and radiocollared 30 coyotes. Per-hour rate of movement averaged 0.87 km and was greater (P = 0.046) during the fawning (1.07 km) than the nonfawning period (0.80 km); areas searched were similar (P = 0.175) between seasons. Coyote habitat use differed during both seasons; habitats were not used in proportion to their availability (P coyote diets were primarily composed of Microtus spp. (65.2%), and consumption of deer was 9.1%. During the study, 19 coyotes died; annual survival rate range was 0.33-0.41, which was low compared with other studies. Consumption of deer was low and coyotes searched open areas (i.e., cropland) more than fawning areas with dense cover. These factors in addition to high coyote mortality suggested that coyote predation was not likely limiting white-tailed deer populations in southeast Minnesota. ?? 2011 The Wildlife Society.

  18. Susceptibility of European red deer (Cervus elaphus elaphus to alimentary challenge with bovine spongiform encephalopathy.

    Mark P Dagleish

    Full Text Available European red deer (Cervus elaphus elaphus are susceptible to the agent of bovine spongiform encephalopathy, one of the transmissible spongiform encephalopathies, when challenged intracerebrally but their susceptibility to alimentary challenge, the presumed natural route of transmission, is unknown. To determine this, eighteen deer were challenged via stomach tube with a large dose of the bovine spongiform encephalopathy agent and clinical signs, gross and histological lesions, presence and distribution of abnormal prion protein and the attack rate recorded. Only a single animal developed clinical disease, and this was acute with both neurological and respiratory signs, at 1726 days post challenge although there was significant (27.6% weight loss in the preceding 141 days. The clinically affected animal had histological lesions of vacuolation in the neuronal perikaryon and neuropil, typical of transmissible spongiform encephalopathies. Abnormal prion protein, the diagnostic marker of transmissible encephalopathies, was primarily restricted to the central and peripheral nervous systems although a very small amount was present in tingible body macrophages in the lymphoid patches of the caecum and colon. Serial protein misfolding cyclical amplification, an in vitro ultra-sensitive diagnostic technique, was positive for neurological tissue from the single clinically diseased deer. All other alimentary challenged deer failed to develop clinical disease and were negative for all other investigations. These findings show that transmission of bovine spongiform encephalopathy to European red deer via the alimentary route is possible but the transmission rate is low. Additionally, when deer carcases are subjected to the same regulations that ruminants in Europe with respect to the removal of specified offal from the human food chain, the zoonotic risk of bovine spongiform encephalopathy, the cause of variant Creutzfeldt-Jakob disease, from consumption of

  19. Dietary Response of Sympatric Deer to Fire Using Stable Isotope Analysis of Liver Tissue

    David M. Leslie, Jr.

    2009-12-01

    Full Text Available Carbon (δ13C and nitrogen (δ15N isotopes in biological samples from large herbivores identify photosynthetic pathways (C3 vs. C4 of plants they consumed and can elucidate potential nutritional characteristics of dietary selection. Because large herbivores consume a diversity of forage types, δ13C and δ15N in their tissue can index ingested and assimilated diets through time. We assessed δ13C and δ15N in metabolically active liver tissue of sympatric mule deer (Odocoileus hemionus and white-tailed deer (O. virginianus to identify dietary disparity resulting from use of burned and unburned areas in a largely forested landscape. Interspecific variation in dietary disparity of deer was documented 2–3 years post-fire in response to lag-time effects of vegetative response to burning and seasonal (i.e., summer, winter differences in forage type. Liver δ13C for mule deer were lower during winter and higher during summer 2 years post-fire on burned habitat compared to unburned habitat suggesting different forages were consumed by mule deer in response to fire. Liver δ15N for both species were higher on burned than unburned habitat during winter and summer suggesting deer consumed more nutritious forage on burned habitat during both seasons 2 and 3 years post-fire. Unlike traditional methods of dietary assessment that do not measure uptake of carbon and nitrogen from dietary components, analyses of stable isotopes in liver or similar tissue elucidated δ13C and δ15N assimilation from seasonal dietary components and resulting differences in the foraging ecology of sympatric species in response to fire.

  20. Serosurveillance for livestock pathogens in free-ranging mule deer (Odocoileus hemionus.

    Annette Roug

    Full Text Available Routine disease surveillance has been conducted for decades in mule deer (Odocoileus hemionus in California for pathogens shared between wildlife and domestic ruminants that may have implications for the animal production industry and wildlife health. Deer sampled from 1990 to 2007 (n = 2,619 were tested for exposure to six pathogens: bluetongue virus (BTV, epizootic hemorrhagic disease virus (EHDV, bovine viral diarrhea virus (BVDV, Leptospira spp., Anaplasma spp. and Brucella spp. We evaluated the relationship between exposure to these pathogens and demographic risk factors to identify broad patterns in seroprevalence across a large temporal and spatial scale. The overall seroprevalence for the entire study period was 13.4% for BTV, 16.8% for EHDV, 17.1% for BVDV, 6.5% for Leptospira spp., 0.2% for Brucella spp., and 17% for Anaplasma spp. Antibodies against BTV and EHDV were most prevalent in the deer populations of southern California. Antibodies against Leptospira spp. and Anaplasma spp. were most prevalent in coastal and central northern California whereas antibodies against BVDV were most prevalent in central-eastern and northeastern California. The overall seroprevalence for Anaplasma spp. was slightly lower than detected in previous studies. North and central eastern California contains large tracts of federal land grazed by livestock; therefore, possible contact between deer and livestock could explain the high BVDV seroprevalence found in these areas. Findings from this study will help to establish baseline values for future comparisons of pathogen exposure in deer, inform on long-term trends in deer population health and provide relevant information on the distribution of diseases that are shared between wildlife and livestock.

  1. Bohr effect and temperature sensitivity of hemoglobins from highland and lowland deer mice.

    Jensen, Birgitte; Storz, Jay F; Fago, Angela

    2016-05-01

    An important means of physiological adaptation to environmental hypoxia is an increased oxygen (O2) affinity of the hemoglobin (Hb) that can help secure high O2 saturation of arterial blood. However, the trade-off associated with a high Hb-O2 affinity is that it can compromise O2 unloading in the systemic capillaries. High-altitude deer mice (Peromyscus maniculatus) have evolved an increased Hb-O2 affinity relative to lowland conspecifics, but it is not known whether they have also evolved compensatory mechanisms to facilitate O2 unloading to respiring tissues. Here we investigate the effects of pH (Bohr effect) and temperature on the O2-affinity of high- and low-altitude deer mouse Hb variants, as these properties can potentially facilitate O2 unloading to metabolizing tissues. Our experiments revealed that Bohr factors for the high- and low-altitude Hb variants are very similar in spite of the differences in O2-affinity. The Bohr factors of deer mouse Hbs are also comparable to those of other mammalian Hbs. In contrast, the high- and low-altitude variants of deer mouse Hb exhibited similarly low temperature sensitivities that were independent of red blood cell anionic cofactors, suggesting an appreciable endothermic allosteric transition upon oxygenation. In conclusion, high-altitude deer mice have evolved an adaptive increase in Hb-O2 affinity, but this is not associated with compensatory changes in sensitivity to changes in pH or temperature. Instead, it appears that the elevated Hb-O2 affinity in high-altitude deer mice is compensated by an associated increase in the tissue diffusion capacity of O2 (via increased muscle capillarization), which promotes O2 unloading.

  2. Effect of the association of cattle and rusa deer (Cervus timorensis russa) on populations of cattle ticks (Boophilus microplus).

    Barre, N; Bianchi, M; De Garine-Wichatitsky, M

    2002-10-01

    The wild population of rusa deer (Cervus timorensis russa) in New Caledonia (South Pacific) is nearly as large as the cattle population. The cattle tick is widespread and occurs all year round. Opinions are divided on the role of deer in the biological cycle of the tick: i) Do they maintain a sustainable tick population that is secondarily available for cattle? ii) Do they decrease the infestation of the environment by collecting larvae on the pasture, but preventing their development to the engorged female stage? or iii) Do they contribute to both situations? An experiment was conducted in three groups of pastures, each seeded with 450 000 larvae/ha and allowed to be grazed only by cattle, only by deer, and by a mixed herd of deer and cattle (deer representing 30% of the biomass), at approximately the same stocking rate (470-510 kg/ha). After 15 months of exposure, the tick burden per weight unit of host was 42 ticks/kg for the steers-only herd and 0.01/kg for the deer-only herd. The steers in the "mixed group" harbored 7 times fewer ticks (6.2/kg) than the cattle-only group, and the deer in the "mixed group," 130 times more (1.3/kg) than the deer-only group. Five emergency acaricide treatments had to be applied in the cattle-only group, but none in the other groups. The long-term sustainability of a viable tick population on deer as well as the potential benefit resulting from the association of deer and susceptible cattle in the tick control of cattle are highlighted.

    2006-10-01

    A critical concern in the transmission of prion diseases, including chronic wasting disease (CWD) of cervids, is the potential presence of prions in body fluids. To address this issue directly, we exposed cohorts of CWD-naïve deer to saliva, blood, or urine and feces from CWD-positive deer. We found infectious prions capable of transmitting CWD in saliva (by the oral route) and in blood (by transfusion). The results help to explain the facile transmission of CWD among cervids and prompt caution concerning contact with body fluids in prion infections.

  5. Antioxidant activity of hydrolysates of deer bone gelatin in a liposome

    ZHAO Yuhong; GAO Tian; ZHANG Ligang

    2007-01-01

    Gelatin extracted from deer bone was hydrolyzed for 3.5-120 min. The degree of hydrolysis was higher from Alcalase-hydrolyzed gelatin than that from neutral proteinase-hydrolyzed gelatin. Alcalase-hydrolyzed gelatin exhibited a stronger antioxidant activity than that of neutral proteinase-hydrolyzed gelatin. Hydrolysates showed strong radical-scavenging ability and Fe2+-chelating activity, both of which were influenced by hydrolysis time. Although nonhydrolyzed gelatin displayed a certain antioxidative effect, it was far less than that of hydrolysates. The hydrolysates of deer bone gelatin can work as a radical stabilizer and metal ion chelator to inhibit lipid oxidation.

    Deer bone has been used as a health-enhancing food as well as an antiaging agent in traditional Oriental medicine. Recently, the water extract of deer bone (DBE) showed a neuroprotective action against glutamate or Aβ1–42-induced cell death of mouse hippocampal cells by exerting antioxidant activity through the suppression of MAP kinases. The present study is to examine whether DBE improves memory impairment induced by scopolamine. DBE (50, 100 or 200 mg/kg) was administered orally to mice fo...

  9. Chronic Wasting Disease of Deer and Elk in Transgenic Mice: Oral Transmission and Pathobiology

    Trifilo, Matthew J.; Ying, Ge; Teng, Chao; Oldstone, Michael B. A.

    2007-01-01

    To study the pathogenesis of chronic wasting disease (CWD) in deer and elk, transgenic (tg) mice were generated that expressed the prion protein (PrP) of deer containing a glycine at amino acid (aa) 96 and a serine at aa 225 under transcriptional control of the murine PrP promoter. This construct was introduced into murine PrP-deficient mice. As anticipated, neither non-tg mice nor PrP ko mice were susceptible when inoculated intracerebrally (i.c.) or orally with CWD brain material (scrapie p...

    Yin, Yupeng; Tang, Lina; Zhang, Jiabao; Tang, Bo; Li, Ziyi

    2011-01-01

    Background One important protein family that functions in nucleotide excision repair (NER) factors is the SNF2 family. A newly identified mouse ERCC6-like gene, Ercc6l (excision repair cross-complementing rodent repair deficiency, complementation group 6-like), has been shown to be another developmentally related member of the SNF2 family. Methodology/Principal Findings In this study, Sika deer Ercc6l cDNA was first cloned and then sequenced. The full-length cDNA of the Sika deer Ercc6l gene ...

  13. Neutron activation analysis of trace metals in the livers of Japanese sika deer (cervus Nippon)

    Neutron activation analysis facilities at the JMTR reactor was used to determine the levels of trace metals in the livers of nine Japanese sika deer. The samples were cut into pieces, pulverized in liquid nitrogen, freeze-dried, and finally fractionated through a stainless steel sieve of 200 mesh. Then the samples were irradiated for 6 or 24 hours by a neutron flux of 1.0x1014 n·cm-2·sec-1. In the present work, we analysed the concentrations of six elements (Ag, Co, Fe, Rb, Se, and Zn) in the livers of nine deer. (author)

    The diversity of Babesia species infecting cervids in parts of central and southern Spain was analyzed by collecting blood from farmed red deer (Cervus elaphus). Babesia sp. was isolated in vitro from two red deer herds in Cádiz and Ciudad Real. The number of Babesia sp. carriers differed between the two herds: 36/77 in Cádiz and 1/35 in Ciudad Real. Hyalomma lusitanicum was the most prevalent tick species identified on the Cádiz farm vegetation and on sampled animals, and is therefore a cand...

  16. Is there adaptation of the exocrine pancreas in wild animal? The case of the Roe Deer

    Guilloteau Paul

    2012-05-01

    Full Text Available Abstract Background Physiology of the exocrine pancreas has been well studied in domestic and in laboratory animals as well as in humans. However, it remains quite unknown in wildlife mammals. Roe deer and cattle (including calf belong to different families but have a common ancestor. This work aimed to evaluate in the Roe deer, the adaptation to diet of the exocrine pancreatic functions and regulations related to animal evolution and domestication. Results Forty bovine were distributed into 2 groups of animals either fed exclusively with a milk formula (monogastric or fed a dry feed which allowed for rumen function to develop, they were slaughtered at 150 days of age. The 35 Roe deer were wild animals living in the temperate broadleaf and mixed forests, shot during the hunting season and classified in two groups adult and young. Immediately after death, the pancreas was removed for tissue sample collection and then analyzed. When expressed in relation to body weight, pancreas, pancreatic protein weights and enzyme activities measured were higher in Roe deer than in calf. The 1st original feature is that in Roe deer, the very high content in pancreatic enzymes seems to be related to specific digestive products observed (proline-rich proteins largely secreted in saliva which bind tannins, reducing their deleterious effects on protein digestion. The high chymotrypsin and elastase II quantities could allow recycling of proline-rich proteins. In contrast, domestication and rearing cattle resulted in simplified diet with well digestible components. The 2nd feature is that in wild animal, both receptor subtypes of the CCK/gastrin family peptides were present in the pancreas as in calf, although CCK-2 receptor subtype was previously identified in higher mammals. Conclusions Bovine species could have lost some digestive capabilities (no ingestion of great amounts of tannin-rich plants, capabilities to secrete high amounts of proline-rich proteins

  17. White-Tailed Deer Browse Preferences in a Southern Bottomland Hardwood Forest

    The authors examined spring and summer use of browse by white-tailed deer in forest gaps created by group selection timber harvest at the SRS. Total percentage browse was low in both years, averaging 2.5% of the available browse. Six species were rated high use, 4 species as proportional use and 10 species as low use. Ratings were in agreement to others in the Southeast. Preferred species were maple, winged elm, greenbriar and black willow. Deer browse had very little impact on regeneration of most species

  18. Forage intake rates of mule deer estimated with fallout cesium-137

    Forage intake rates of 87 wild, Rocky Mountain mule deer (Odocoileus hemionus) collected over a 2-year period from the Cache la Poudre Drainage, Colorado, were estimated utilizing available data on fallout cesium-137 concentrations in the deer and their inferred diet. The method employed involved the convolution of an intake function and a retention function. Ingestion rates are reported and analyzed by sex, season, and age class. An overall mean forage intake of 21.9 grams air dry forage/kg carcass weight/day was calculated. Adult animals consumed significantly (less than 0.01) more than adults throughout the year. (U.S.)

  19. The endemic plants of Micronesia: a geographical checklist and commentary

    Lorence, D.H.

    2012-05-01

    Full Text Available The Micronesia-Polynesia bioregion is recognized as a global biodiversity hotspot. However, until now estimates regarding the number of endemic plant species for the region were not supported by any comprehensive published work for the region. The results of this study indicate that Micronesia has the world’s highest percentage of plant endemism per square kilometer out of all globally recognized insular biodiversity hotspots. A checklist of all endemic plant species for Micronesia is presented here with their corresponding geographical limits within the region. A summary of previous work and estimates is also provided noting the degree of taxonomic progress in the past several decades. A total of 364 vascular plant species are considered endemic to Micronesia, most of them being restricted to the Caroline Islands with a large percentage restricted to Palau. The checklist includes seven new combinations, one new name, and two unverified names that require additional study to verify endemic status. Overviews of each respective botanical family represented in the list are given including additional information on the Micronesian taxa. Recommendations for future work and potential projects are alluded to throughout the text highlighting major data gaps and very poorly known taxa. The following new combinations and names are made: Cyclosorus carolinensis (Hosokawa Lorence, comb. nov. , Cyclosorusgretheri (W. H.

    2009-08-01

    The incidence of severe burn is extremely high in the Low and Middle Income Countries with an estimated 90% of the world incidence of which 50% is in South East Asia. Through an earlier analysis of 11,196 burn admission over 8 years (1993-2000--Phase I) to our burn unit we established the endemic nature of the injury [Ahuja RB, Bhattacharya S. An analysis of 11,196 burn admissions and evaluation of conservative management techniques. Burns 2002;28:555-61]. A continued analysis of 5566 burn admissions over the next 7 years (2001-2007--Phase II) and its comparison with the Phase I reveals a significant change in the epidemiological profile. The average yearly admissions have fallen by 43.14%, from 1399.5 patients in Phase I to 795.14 patients in Phase II. This fall in average yearly admissions is predominant in the age group 16-35 years (52.61% decline) and 36-55 years (46.51% decline). The overall female to male ratio has also changed from 1.26:1 to 0.91:1. However, the overall mean %TBSA burn has reduced only mildly from 49.12% TBSA in Phase I to 44.39% in Phase II. During Phase II there was also a significant decline of 46.93% and 56.25% in the yearly admission of flame and scald burn respectively. Non-intentional incidents still remain the main mode of injury accounting for 87.12% in Phase I and 89.89% in Phase II. But, the yearly admissions of non-intentional burns fell from 1219.25 in Phase I to 714.71 in Phase II, which is a significant drop of 41.38%. Kitchen continues to dominate as the main location for flame incidents, but the yearly admission rate from kitchen accidents dropped from 897.5 patients in Phase I to 368.43 patients in Phase II. At the same time, liquefied petroleum gas (LPG) leaks which accounted for only 0.72% of all kitchen accidents in Phase I rose to 10.74% in Phase II. Another redeeming feature is the reduction in overall mortality from 51.8% in Phase I to 40.20% in Phase II. Interestingly, a very significant negative correlation exists

  1. Does Large Genome Size Limit Speciation in Endemic Island Floras?

    Maxim V. Kapralov

    2011-01-01

    Full Text Available Genome sizes in plants vary by several orders of magnitude, and this diversity may have evolutionary consequences. Large genomes contain mainly noncoding DNA that may impose high energy and metabolic costs for their bearers. Here we test the large genome constraint hypothesis, which assumes that plant lineages with large genomes are diversifying more slowly Knight et al. (2005, using endemic floras of the oceanic archipelagos of the Canaries, Hawaii, and Marquesas Islands. In line with this hypothesis, the number of endemic species per genus is negatively correlated with genus-average genome size for island radiations on Hawaiian and Marquesas archipelagos. However, we do not find this correlation on the Canaries, which are close to the continent and therefore have higher immigration rate and lower endemism compared to Hawaii. Further work on a larger number of floras is required to test the generality of the large genome constraint hypothesis.

    2004-03-01

    The risk of dengue virus infection to travelers visiting dengue fever endemic regions was studied through the use of mathematical modeling. A Susceptible-Infected-Recovered (SIR) model is used to describe the transmission of dengue fever (DF) in an endemic region into which tourists enter. The dynamics of a new class of human, the traveler, is incorporated into the systems of first order differential equations in the SIR describing the dynamics of the transmission in the host region. Using standard dynamic analysis methods, the numbers of travelers who become infected with the dengue virus are calculated as a function of the length of time the tourist stays in the region.

    Although rotaviruses have been detected in a variety of host species, there are only limited records of their occurrence in deer, where their role is unknown. In this study, group A rotavirus was identified in roe deer during a study of enteric viruses in game animals. 102 samples of intestinal content were collected from roe deer (56), wild boars (29), chamois (10), red deer (6) and mouflon (1), but only one sample from roe deer was positive. Following whole genome sequence analysis, the rotavirus strain D38/14 was characterized by next generation sequencing. The genotype constellation, comprising 11 genome segments, was G6-P[15]-I2-R2-C2-M2-A3-N2-T6-E2-H3. Phylogenetic analysis of the VP7 genome segment showed that the D38/14 rotavirus strain is closely related to the various G6 zoonotic rotavirus strains of bovine-like origin frequently detected in humans. In the VP4 segment, this strain showed high variation compared to that in the P[15] strain found in sheep and in a goat. This finding suggests that rotaviruses from deer are similar to those in other DS-1 rotavirus groups and could constitute a source of zoonotically transmitted rotaviruses. The epidemiological status of group A rotaviruses in deer should be further investigated. PMID:27374907

  5. Three finger palpation technique of vas deferens for keyhole vasectomy in spotted (Axis axis and sambar deer (Cervus unicolor

    B. J. William

    2014-09-01

    Full Text Available Aim: Vasectomy is performed in deer for population control, maintain pedigreed animals and prevent inbreeding. Conventional procedure of vasectomy required a long-term anesthesia and longer duration of hospitalization, which often result in stress, morbidity and mortality. A study was conducted to capture, neuter and release the deer with minimal hospitalization and stress by adopting three finger palpation technique of vas deferens and performing vasectomy through a key-hole incision. Materials and Methods: The study was conducted on three spotted male deer and three sambar male deer, which were immobilized with a mixture of xylazine at the dose of 1.00 mg/kg and ketamine at the dose of 5.00 mg/kg. The vas deferens could be palpated as a piece of cooked spaghetti at the neck of the scrotum on the anterior aspect by three finger palpation technique and was able to fix the vas deferens between the thumb and middle finger. Through a key-hole incision of <5 mm length, the vas deferens was exteriorized and resected using electrocautery and the skin incision was sealed with methyl methacrylate. The deer were released on the same day, and no post-operative complication was noticed. Conclusion: The study revealed that three finger palpation technique of vas deferens provided guidance for easy access to vas deferens for vasectomy in deer with less hospitalization, and the deer could be released on the same day.

    Enterocytozoon bieneusi is one of the most important zoonotic pathogen that can infect almost all animals, including humans. However, little information is available regarding prevalence and genotypes of E. bieneusi in sika deer. In the present study, the prevalence of E. bieneusi infection in sika deer in Jilin province, Northeastern China was examined using PCR amplification of the internal transcribed spacer (ITS) region of the ribosomal RNA (rRNA) gene. 23 (7.06%) of 326 samples were tested E. bieneusi-positive, and the risk factor significantly associated with E. bieneusi prevalence was the age of sika deer. Sequence analysis of the ITS rRNA gene suggested that 8 genotypes of E. bieneusi were found in this study, with five known genotypes, namely J (n = 11), BEB6 (n = 4), EbpC (n = 1), CHN-DC1 (n = 1), KIN-1 (n = 1) and three novel genotypes, namely JLD-1 (n = 2), JLD-2 (n = 2) and JLD-3 (n = 1). Phylogenetic analysis indicated that genotypes CHN-DC-1, KIN-1, EbpC, JLD-2 and JLD-3 fell into group 1, while other three genotypes (genotypes J, BEB6 and JLD-1) were clustered into group 2 (so-called bovine-specific groups). These findings indicated the presence of zoonotic E. bieneusi in Jilin province, Northeastern China. Effective strategies should be performed to control E. bieneusi infection in sika deer, other animals and humans. PMID:27078663

  8. Unfencing the Range: History, Identity, Property, and Apocalypse in "Lame Deer Seeker of Visions."

    Sanborn, Geoff

    1990-01-01

    Seemingly chaotic to Western eyes, John Lame Deer's autobiography has a meaningful structure based on Lakota numerology and oral tradition. The book explores conflicts between White and Indian conceptions of identity and property, and sees itself as an instrument in the apocalyptic triumph of Indian spirituality over White greed. (SV)

  9. Mismatch between birth date and vegetation phenology slows the demography of roe deer.

    Floriane Plard

    2014-04-01

    Full Text Available Marked impacts of climate change on biodiversity have frequently been demonstrated, including temperature-related shifts in phenology and life-history traits. One potential major impact of climate change is the modification of synchronization between the phenology of different trophic levels. High phenotypic plasticity in laying date has allowed many bird species to track the increasingly early springs resulting from recent environmental change, but although changes in the timing of reproduction have been well studied in birds, these questions have only recently been addressed in mammals. To track peak resource availability, large herbivores like roe deer, with a widespread distribution across Europe, should also modify their life-history schedule in response to changes in vegetation phenology over time. In this study, we analysed the influence of climate change on the timing of roe deer births and the consequences for population demography and individual fitness. Our study provides a rare quantification of the demographic costs associated with the failure of a species to modify its phenology in response to a changing world. Given these fitness costs, the lack of response of roe deer birth dates to match the increasingly earlier onset of spring is in stark contrast with the marked phenotypic responses to climate change reported in many other mammals. We suggest that the lack of phenotypic plasticity in birth timing in roe deer is linked to its inability to track environmental cues of variation in resource availability for the timing of parturition.

  15. Prevalence and Sequence-Based Identity of Rumen Fluke in Cattle and Deer in New Caledonia.

    Laura Cauquil

    Full Text Available An abattoir survey was performed in the French Melanesian archipelago of New Caledonia to determine the prevalence of paramphistomes in cattle and deer and to generate material for molecular typing at species and subspecies level. Prevalence in adult cattle was high at animal level (70% of 387 adult cattle and batch level (81%. Prevalence was lower in calves at both levels (33% of 484 calves, 51% at batch level. Animals from 2 of 7 deer farms were positive for rumen fluke, with animal-level prevalence of 41.4% (29/70 and 47.1% (33/70, respectively. Using ITS-2 sequencing, 3 species of paramphistomes were identified, i.e. Calicophoron calicophorum, Fischoederius elongatus and Orthocoelium streptocoelium. All three species were detected in cattle as well as deer, suggesting the possibility of rumen fluke transmission between the two host species. Based on heterogeneity in ITS-2 sequences, the C. calicophorum population comprises two clades, both of which occur in cattle as well as deer. The results suggest two distinct routes of rumen fluke introduction into this area. This approach has wider applicability for investigations of the origin of rumen fluke infections and for the possibility of parasite transmission at the livestock-wildlife interface.

  16. Bovine Viral Diarrhea Virus (BVDV) in White-Tailed Deer (Odocoileus virginianus).

    Passler, Thomas; Ditchkoff, Stephen S; Walz, Paul H

    2016-01-01

    Bovine viral diarrhea virus (BVDV) is the prototypic member of the genus Pestivirus in the family Flaviviridae. Infections with BVDV cause substantial economic losses to the cattle industries, prompting various organized control programs in several countries. In North America, these control programs are focused on the identification and removal of persistently infected (PI) cattle, enhancement of BVDV-specific immunity through vaccination, and the implementation of biosecure farming practices. To be successful, control measures must be based on complete knowledge of the epidemiology of BVDV, including the recognition of other potential sources of the virus. BVDV does not possess strict host-specificity, and infections of over 50 species in the mammalian order Artiodactyla have been reported. Over 50 years ago, serologic surveys first suggested the susceptibility of white-tailed deer (Odocoileus virginianus), the most abundant free-ranging ruminant in North America, to BVDV. However, susceptibility of white-tailed deer to BVDV infection does not alone imply a role in the epidemiology of the virus. To be a potential wildlife reservoir, white-tailed deer must: (1) be susceptible to BVDV, (2) shed BVDV, (3) maintain BVDV in the population, and (4) have sufficient contact with cattle that allow spillback infections. Based on the current literature, this review discusses the potential of white-tailed deer to be a reservoir for BVDV. PMID:27379074

  17. The construction of cloned Sika deer embryos (Cervus nippon hortulorum) by demecolcine auxiliary enucleation.

    Yin, Y; Mei, M; Zhang, D; Zhang, S; Fan, A; Zhou, H; Li, Z

    2014-02-01

    The objective of our study was to establish the feasibility of experimental protocols for cloning sika deer. We performed auxiliary enucleation to improve the efficiency of nuclear transfer operation by optimizing the demecolcine concentration to induce cytoplasmic protrusions in the sika deer oocytes. In the present study,we had studied the impact of different demecolcine concentrations on cytoplasmic protrusions and enucleation rates. We determined that 95.9% of the sika deer oocytes formed cytoplasmic protrusions when treated for 1 h with 0.8 μg/ml demecolcine. The lowest observed rate of protrusion was 19.3% after overnight treatment with demecolcine. When the oocytes aged or had a poor cumulus expansion, they exhibited a significant decrease in the ability to form cytoplasmic protrusions. The rates of enucleation (94.9% vs 85.8%, p sika deer oocytes could be enucleated quickly and effectively using demecolcine auxiliary enucleation, which could enhance the enucleation rate, cell fusion rate and blastocyst rate of cloned embryos in vitro.

  18. Incidence and Injury Types in Motorcycle Collisions Involving Deer in Western New York.

    Smith, Bradley W; Buyea, Cathy M; Anders, Mark J

    2015-06-01

    Motorcycle popularity, urban sprawl, and large deer populations result in a significant number of deer-motorcycle collisions. This retrospective review of a level I trauma center in Buffalo, New York, revealed that 40 of 487 (8.2%) of patients admitted because of motorcycle crashes from May 2007 through June 2011 involved deer. There were 120 total injuries: the most common were orthopedic (39/120; 32.5%), chest (38/120; 31.7%), head (18/120; 15.0%), spine (10/120; 8.3%), facial (8/120; 6.7%), and abdominal (7/120; 5.8%). Thirty-five of 40 (87.5%) were men and were older (48.9 years, [SD, 8.9 years]) than the average for all motorcycle crashes during the study period (41.9 years, [SD, 13.9 years]). Mean (SD) injury severity score was 17.1 (9.8), reflecting the severity of encountered injuries. This study highlights the relatively common risk that deer pose to the motorcyclist and is comparable to published series in more rural Midwestern settings. PMID:26047002

  19. Global reach: Red Deer oilfield expertise, not least in taming disasters, lures international clientele

    Lorenz, A.

    2002-10-07

    The rise to international prominence of two Red Deer, Alberta, firms --Safety Boss and Red Flame -- by performing heroic feats in Kuwait's flaming oil fields, are chronicled. These two firms, along with several others in Red Deer, provide expertise in fire fighting that is sought after by petroleum companies in the farthest corners of the world. Red Deer companies can be found training Kazakhs, Russians, Kuwaitis, Iranians, and Turkmen in fighting oil well fires. Red Flame, for example developed a method called 'hot-tapping' while fighting blazing oil well fires in Kuwait, which they have since extended by developing hot-tapping equipment that would work on the highest pressure wells in the world. Last summer Red Flame personnel trained a Schlumberger crew in Kazakhstan working on custom-designed equipment that could perform at pressures of 5,000 psi. Red Flame also designed 'extended reach' hot-tapping in response to a request from Petro-Canada. Meanwhile, Safety Boss, the oldest and best known oil well fire fighting company in Canada, boasts of having extinguished 180 wells in their 1991 stint in Kuwait, while their closest competitor, Texas-based Wild Well, doused only 117. With improved safety policies and procedures the number of oil well blow-outs diminished dramatically in recent years, but there are always opportunities for the Red Deer expertise somewhere around the world.

    2015-07-30

    Neospora caninum is a worldwide protozoan that can induce neuromuscular disease in dogs and reproductive failure in domestic and wild ruminants. The objective of the present investigation was to determine the seroprevalence of N. caninum infection in farmed sika deer in China as little is known of this host-parasite relationship. A total of 1800 serum samples were collected during 2013 and 2014 from farmed sika deer in the major production areas of Liaoning, Jilin and Heilongjiang provinces.Assay by ELISA for N. caninum antibodies indicated a seroprevalence of 13.6% in 2013 and 15.8% in 2014, varying in different regions from 9.5% to 27.5%. Statistical analysis revealed that prevalence in animals aged >4 years (20.4%) was significantly higher than in the age ranges sika deer in herds with a history of miscarriage (41.9%) had a significantly higher seroprevalence than in those without (12.6%) (Psika deer in China and provides base-line data for the design and evaluation of measures for its control and prevention in this host.

    We report in vitro culture of zoonotic Babesia sp. EU1 from blood samples of roe deer in France. This study provides evidence of transovarial and transstadial transmission of the parasite within Ixodes ricinus, which suggests that this tick could be a vector and reservoir of EU1.

    Delineating populations is critical for understanding population dynamics and managing habitats. Our objective was to delineate subpopulations of migratory female white-tailed deer (Odocoileus virginianus) in the central Black Hills, South Dakota and Wyoming, USA, on summer and winter ranges. We used fuzzy classification to assign radiocollared deer to subpopulations based on spatial location, characterized subpopulations by trapping sites, and explored relationships among survival of subpopulations and habitat variables. In winter, Kaplan-Meier estimates for subpopulations indicated 2 groups: high (S = 0.991 ?? 0.005 [x- ?? SE]) and low (S = 0.968 ?? 0.007) weekly survivorship. Survivorship increased with basal area per hectare of trees, average diameter at breast height of trees, percent cover of slash, and total point-center quarter distance of trees. Cover of grass and forbs were less for the high survivorship than the lower survivorship group. In summer, deer were spaced apart with mixed associations among subpopulations. Habitat manipulations that promote or maintain large trees (i.e., basal area = 14.8 m2/ha and average dbh of trees = 8.3 cm) would seem to improve adult survival of deer in winter.

    2005-03-10

    As a direct and indirect consequence of human activities, only two subspecies, Cervus nippon sinchuanicus and Cervus nippon kopschi, currently subsist in the wild of China. However, a large population of Cervus nippon hortulorum and Cervus nippon nippon is raised in order to gain deer parts for Chinese traditional medicine. According to Chinese Wild Animal Conservation Law, hunting, capturing and trading of the wild sika deer are strictly banned, however, raising and trading of the domestic individual are permitted. Thus, it is very necessary to identify the subspecies of sika deer in China in forensic tests. In our study, we used mitochondrial DNA control region sequence analysis and phylogenetic analysis to identify the subspecies of sika deer. Mitochondrial DNA control region sequences analysis revealed that two haplotypes came from the unknown samples. One is the same as the haplotype that came from the samples of wild population of C. n. kopschi. Phylogenetic analysis indicated that the two haplotypes of unknown samples clustered with the haplotypes of C. n. kopschi, and had significant difference from the haplotypes of the other subspecies. These results together revealed that the unknown samples came from two individuals that belong to the wild population of C. n. kopschi living in the Qinglingfeng State Natural Reserve of Zhejiang province. Therefore, the results provide forensic evidence of illegal wild animal hunting. PMID:15639603

  7. Linking bovine tuberculosis on cattle farms to white-tailed deer and environmental variables using Bayesian hierarchical analysis.

    W David Walter

    Full Text Available Bovine tuberculosis is a bacterial disease caused by Mycobacterium bovis in livestock and wildlife with hosts that include Eurasian badgers (Meles meles, brushtail possum (Trichosurus vulpecula, and white-tailed deer (Odocoileus virginianus. Risk-assessment efforts in Michigan have been initiated on farms to minimize interactions of cattle with wildlife hosts but research on M. bovis on cattle farms has not investigated the spatial context of disease epidemiology. To incorporate spatially explicit data, initial likelihood of infection probabilities for cattle farms tested for M. bovis, prevalence of M. bovis in white-tailed deer, deer density, and environmental variables for each farm were modeled in a Bayesian hierarchical framework. We used geo-referenced locations of 762 cattle farms that have been tested for M. bovis, white-tailed deer prevalence, and several environmental variables that may lead to long-term survival and viability of M. bovis on farms and surrounding habitats (i.e., soil type, habitat type. Bayesian hierarchical analyses identified deer prevalence and proportion of sandy soil within our sampling grid as the most supported model. Analysis of cattle farms tested for M. bovis identified that for every 1% increase in sandy soil resulted in an increase in odds of infection by 4%. Our analysis revealed that the influence of prevalence of M. bovis in white-tailed deer was still a concern even after considerable efforts to prevent cattle interactions with white-tailed deer through on-farm mitigation and reduction in the deer population. Cattle farms test positive for M. bovis annually in our study area suggesting that the potential for an environmental source either on farms or in the surrounding landscape may contributing to new or re-infections with M. bovis. Our research provides an initial assessment of potential environmental factors that could be incorporated into additional modeling efforts as more knowledge of deer herd

  8. Reappearance of Taenia ovis krabbei muscle cysts in a roe deer (Capreolus capreolus) in Denmark after 60+ years

    2013-01-01

    The present report describes the reappearance of Taenia ovis krabbei in a roe deer from Denmark after more than 60 years. The cysticerci were isolated from the thigh muscle of the deer, and the diagnosis was based on histostological analysis, morphology of the rostellar-hooks as well as molecular...... typing of the mitochondrial cytochrome c oxidase I (cox1) gene. The exact definitive host was not revealed in this report, but domestic dogs may play a role of the definitive host in the area. This finding is of concern to hunters and deer meat producers, since the infected meat is usually condemned due...

    2014-12-01

    Full Text Available Deer antler is a precious animal-sourced traditional Chinese medicine. We aimed to rapidly assess the quality of deer antler slices by electronic nose so that we can ensure medical safety. In this study, response intensity of the electronic nose was favorably optimized, and samples were well assessed by using an electronic nose based on LDA model. The results obtained herein suggested that electronic nose could be an effective method to rapidly assess the quality of deer antler slices, and could also be an important tool for categorization of complex aroma mixtures for the control of quality of drugs or food.

  11. The content of selected metals in muscles of the red deer (Cervus elaphus) from Poland.

    Skibniewski, Michał; Skibniewska, Ewa M; Kośla, Tadeusz

    2015-06-01

    The aim of this study was to evaluate the concentrations of Pb, Cu, Zn, Rb, Cs, Sr and Ba in the muscles of red deer that were hunted in two regions of Poland (south-western and north-eastern). The data obtained were evaluated with regards to benefits and potential risk to consumers' health. Samples for the investigations were collected in 2008 and 2009 from 50 female red deer, and the metal concentrations were determined by using the inductively coupled plasma-mass spectrometric (ICP-MS) method. The mean concentrations of Pb did not differ statistically between regions and were equal to that permitted for farm animals. The results of this study support the conclusion that the meat of the analysed animals does not pose a risk of lead intoxication. Statistically higher mean concentrations of Cu and Zn were found in the muscles of red deer from the south-western region (namely, 2.99 and 25.78 mg kg(-1)) than those in animals from north-eastern Poland (namely, 2.61 and 23.39 mg kg(-1) wet weight). In terms of human nutritional needs, the meat of red deer can be considered as a good source of Cu and Zn. Furthermore, Rb, Cs, Sr and Ba concentrations did not differ statistically between regions. Their mean concentrations were 4.50, 0.09, 0.16 and 0.31 mg kg(-1) wet weight, respectively. Although high Cs, Sr and Ba concentrations were found, the meat of red deer does not pose a risk for adult consumers. Only high Ba content may potentially result in negative health effects for children. PMID:25548020

    Full Text Available Abstract Background Our American College of Surgeons Level 1 Trauma Center serves a rural population. As a result, there is a unique set of accidents that are not present in an urban environment such as deer related motor vehicle crashes (dMVC. We characterized injury patterns between motorcycle/all-terrain vehicles (MCC and automobile (MVC crashes related to dMVC (deer motor vehicle crash with the hypotheses that MCC will present with higher Injury Severity Score (ISS and that it would be related to whether the driver struck the deer or swerved. Methods The records of 157 consecutive patients evaluated at our institution for injury related to dMVC from January 1st, 1997 to December 31st, 2006 were reviewed from our prospectively collected trauma database. Demographic, clinical, and crash specific parameters were abstracted. Injury severity was analyzed by the Abbreviated Injury Scale score for each body region as well as the overall Injury Severity Score (ISS. Results Motorcycle crashes presented with a higher median ISS than MVCs (14 vs 5, p Within the MVC group, there was no difference between swerving and hitting the deer in any AIS group. Forty-seven percent of drivers were not wearing seat belts which resulted in similar median ISS (6 vs 5 and AIS of all body regions. Conclusions Motorcycle operators suffered higher ISS. There were no significant differences in median ISS if a driver involved in a deer-related motor vehicle crash swerved rather than collided, was helmeted, or restrained.

  13. Chronic wasting disease of deer and elk in transgenic mice: oral transmission and pathobiology.

    Trifilo, Matthew J; Ying, Ge; Teng, Chao; Oldstone, Michael B A

    2007-08-15

    To study the pathogenesis of chronic wasting disease (CWD) in deer and elk, transgenic (tg) mice were generated that expressed the prion protein (PrP) of deer containing a glycine at amino acid (aa) 96 and a serine at aa 225 under transcriptional control of the murine PrP promoter. This construct was introduced into murine PrP-deficient mice. As anticipated, neither non-tg mice nor PrP ko mice were susceptible when inoculated intracerebrally (i.c.) or orally with CWD brain material (scrapie pool from six mule deer) and followed for 600+ days (dpi). Deer PrP tg mice were not susceptible to i.c. inoculation with murine scrapie. In contrast, a fatal neurologic disease occurred accompanied by conversion of deer PrPsen to PrPres by western blot and immunohistochemistry after either i.c. inoculation with CWD brain into two lines of tg mice studied (312+32 dpi [mean+2 standard errors] for the heterozygous tg line 33, 275+46 dpi for the heterozygous tg line 39 and 210 dpi for the homozygous tg line 33) or after oral inoculation (381+55 dpi for the homozygous tg line 33 and 370+26 dpi for the homozygous tg line 39). Kinetically, following oral inoculation of CWD brain, PrPres was observed by day 200 when mice were clinically healthy in the posterior surface of the dorsum of the tongue primarily in serous and mucous glands, in the intestines, in large cells at the splenic marginal zone that anatomically resembled follicular dendritic cells and macrophages and in the olfactory bulb and brain stem but did not occur in the cerebellum, cerebral cortex or hippocampus or in hearts, lungs and livers of infected mice. After 350 days when mice become clinically ill the cerebellum, cerebral cortex and hippocampus became positive for PrPres and displayed massive spongiosis, neuronal drop out, gliosis and florid plaques.

  14. Late Quaternary distribution dynamics and phylogeography of the red deer ( Cervus elaphus) in Europe

    Sommer, R. S.; Zachos, F. E.; Street, M.; Jöris, O.; Skog, A.; Benecke, N.

    2008-04-01

    Here we present spatial-temporal patterns for European late Quaternary red deer (Cervus elaphus), based on radiocarbon-supported evidence derived mainly from archaeological sites. This is followed by an overview of the recent phylogeography of this species using haplogroup studies of recent molecular data. The implications of the synthesis of palaeontological and genetic data are discussed and we propose that present day European red deer haplogroup distributions are best explained against the history of late Quaternary population contractions into and expansions from glacial refugia. Around 800 records of Cervus elaphus were assigned to the period covering the later part of the Last Glacial and the Early to Middle Holocene. Red deer becomes increasingly visible in faunal assemblages dated to late OIS-3 (<40.0 ka 14C BP). The species persisted throughout the LGM on the Iberian Peninsula, in adjacent regions of South-Western France (Gascony, Dordogne, Languedoc), on the Italian Peninsula, in the Balkans and Greece, and east of the Carpathians in Moldavia. We suggest that genetic exchange between the populations of the Balkans and the East of the Carpathians remained uninterrupted during the LGM. The expansion of red deer from its southern refugia into Central and Northern Europe begins rapidly at 12,500 14C BP. The expansion of red deer coincides with the sudden rise in temperature at the onset of Greenland Interstadial 1e and the dispersion of open birch woodland into the northern half of Europe. Radiocarbon supported records show a more or less universal distribution of Cervus elaphus across Europe following the Pleistocene/Holocene climatic change at 10.0 ka 14C BP for the first time. Molecular data and fossil record combined provide a clearer temporal and spatial pattern for the Lateglacial recolonisation process of the northern part of Europe.

  15. Detection and genetical characterization of Shiga toxin-producing Escherichia coli from wild deer.

    1998-01-01

    Shiga toxin (Stx)-producing Escherichia coli (STEC) strains isolated from wild deer in Japan were examined. A total of 43 fecal samples were collected 4 times from 4 different sites around Obihiro City, Hokkaido, Japan, in June and July 1997. Seven STEC strains were isolated by PCR screening, all of them were confirmed by ELISA and Vero cell cytotoxicity assay to be producing only active Stx type 2 (Stx2). Moreover, they seemed to carry the hemolysin and eaeA genes of STEC O157:H7, and some isolates harbored large plasmids which were similar to the 90-kilobase virulence plasmid of STEC O157:H7. Based on their plasmid profiles, antibiotic resistance patterns, PCR-based DNA fingerprinting data obtained by using random amplified polymorphic DNA (RAPD) and the stx2 gene sequences, all isolates were divergent from each other except for 3 isolates from the first and second samplings. A DNA sequence analysis of representative isolates revealed that deer originating STEC strains were closely related to each other, but not to the Stx2-producing STEC strains isolated from a mass outbreak in Obihiro at the same time. A phylogenic analysis of the deduced Stx2 amino acid sequences demonstrated that three distinct clusters existed in the deer originating STEC strains and that the Stx of deer originating STEC was closely associated with that originating from humans, but not those of STEC originating from other animals. These results suggest that STEC contamination of deer carcasses should be considered as a potential source of human infection and adequate sanitary inspection of meat for human consumption is also essential for wild animals.

    In the past, Listeria monocytogenes has been isolated from game feces and meat. However, less information is available on the occurrence of L. monocytogenes in other specimens originating from game animals. Hence, the aim of this study was to get an overview of the occurrence and distribution of L. monocytogenes in game animals by characterization of isolates from different matrices. For that purpose, samples were collected from red deer (Cervus elaphus), wild boars (Sus scrofa), and feed during the hunting season 2011-2012 in three different regions of Germany and Austria. Six samples from each animal were examined: tonsils, content of the rumen or the stomach, liver, intestinal lymph nodes, cecum content, and feces. Nineteen of 45 red deer and 12 of 49 wild boars were found to be positive for L. monocytogenes as well as 4 of 22 pooled feed samples. L. monocytogenes was isolated most frequently from the rumen of red deer (14 of 19) and the tonsils of wild boars (7 of 12). Serotypes 1/2a, 1/2b, 4a, and 4b were detected in samples of game animals and feed, and serotypes 1/2a and 4b were the most prevalent serotypes. The presence of L. monocytogenes serotype 4a had not yet been described in red deer. This might be due to the fact that it was only isolated from the content of rumen and that no other study has yet examined ruminal content. Pulsed-field gel electrophoresis showed a wide variety of strains. Some strains occurred in both species and feed samples, but one strain was dominant in one region. The results show that red deer and wild boars can be carriers of L. monocytogenes in different matrices, although the feces samples can be negative. PMID:27159352

  17. Sustainable monitoring of roe deer in public hunting areas in the Spanish Pyrenes

    Herrero, J.; Torres, R. T.; Prada, C.; Garcia-Serrano, A.; Gimenez-Anaya, A.; Fernandez, O.

    2013-07-01

    Aim of study: Monitoring trends in animal populations is essential for the development of appropriate wildlife management strategies. Area of study: The area is situated in the southern Pyrenees (Aragon), Spain. Material and methods: To measure the abundance, population trends, sex ratio, and mortality of roe deer populations, we analyzed data from i) driven hunts for wild boar (hunting seasons 1995/96-2009/10, n = 1,417, ii) itineraries, which were used to calculate the KAI and density using DS (2003-2010, n = 310 itineraries), iii) roe deer carcass recoveries (2006-2010, n = 100), and iv) data from the deer hunting quota fulfillment (2006-2010, n = 325 hunted animals. Main results: Based on DS, in 2010, the average density of roe deer populations was 2.3 km–2 (CV 17%). Based on the KAI and the battues, the estimated average annual rate of increase was 5.8% and 4.3%, respectively. Based on the KAI and the carcass recoveries, the estimates of the population sex ratio were 0.75 (n = 641) and 0.9 (n = 100) males per female, respectively. Carcass recoveries indicated that mortality was highest in late winter and early spring. The average body masses and sizes of males and females were within the ranges reported for other Iberian and European populations. Research highlights: Monitoring should be continued in the Aragon population of roe deer, although larger sample sizes are required to increase the accuracy of estimates and assessments of the impact of management actions.

  18. Movement behavior, dispersal, and the potential for localized management of deer in a suburban environment

    Porter, W.F.; Underwood, H.B.; Woodard, J.L.

    2004-01-01

    We examined the potential for localized management of white-tailed deer (Odocoileus virginianus) to be successful by measuring movements, testing site fidelity, and modeling the effects of dispersal. Fifty-nine females were radiomarked and tracked during 1997 through 2000 in Irondequoit, New York, USA, a suburb of Rochester. We constructed home ranges for those deer with A greater than or equal to 18 reclocations/season. Fifty percent minimum convex polygons (MCP) averaged 3.9 (SE = 0.53) ha in the summer and 5.3 (SE = 0.80) ha in the winter. Deer showed strong fidelity to both summer and winter home ranges, and 30 of 31 females showed overlap of summer and winter home ranges. Annual survival was 64%; the major cause of mortality was deer-automobile collisions. Average annual dispersal rates were <15% for yearlings and adults. Using matrix population modeling, we explored the role of female dispersal in sustaining different management objectives in adjacent locales of approximately 1,000 ha. Modeling showed that if female dispersal was 8%, culling would have to reduce annual survival to 58% to maintain a population just under ecological carrying capacity and reduce survival to 42% to keel) the population at one-half carrying capacity. With the same dispersal, contraception Would need to be effective in 32% of females if the population is near carrying capacity and 68% if the population is at one-half of carrying capacity. Movement behavior data and modeling results lend support to the use of a localized approach to management of females that emphasizes neighborhood-scale manipulation of deer populations, but our research suggests that dispersal rates in females could be critical to long-term success.

    2016-03-01

    The study was performed on 20 (10 males, 10 females) roe deer (Capreolus capreolus) to investigate the concentration of cadmium, lead, mercury, and arsenic in the muscle tissue. They reside in forest and meadow, about 50 km distance from industrial activities and traffic. Samples were taken from the musculus biceps femoris of each deer without external contamination after shooting during the regular hunting season on a hunting area close to Eger in Hungary. The determination of heavy metal contents was carried out by inductively coupled plasma optical emission spectrometry (ICP-OES). The statistical analysis was performed by statistical package for the social sciences (SPSS) version 11.0. The measured residue concentration of cadmium was below the limit of detection in the roe deer meat indicating no health risk for the consumers. The average lead concentration (0.48 ± 0.21 mg/kg wet weight) exceeded the regulated maximum limit, but its calculated weekly intake was below the provisional tolerable weekly intake (PTWI). The residue level of mercury is not regulated and the average mercury content of roe deer meat (0.87 ± 0.40 mg/kg wet weight) was about half of PTWI, but the consumption of meat with the highest detected concentrations results in higher PTWI than recommended. The measured concentration of arsenic (0.27 ± 0.20 mg/kg wet weight) in the roe deer meat may not pose any health risk for the human consumers according to the PTWI set by the World Health Organization.

    2016-01-01

    Amphitecna loreae Ortiz-Rodr. & Burelo, sp. nov. (Bignoniaceae), a new species endemic to the karst rainforest in southern Mexico, is described and illustrated. The new species differs from the other species of Amphitecna by the combination of cauliflorous inflorescences, larger flowers, buds rounded at apex, and globose-ellipsoid rather than acuminate fruits. A key to the Mexican species of Amphitecna is presented.

    2016-01-01

    The legume genus Mimosa has > 500 species, with two major centres of diversity, Brazil (c. 350 spp.) and Mexico (c. 100 spp.). In Brazil most species are nodulated by Burkholderia. Here we asked whether this is also true of native and endemic Mexican species. We have tested this apparent affinity for betaproteobacteria by examining the symbionts of native and endemic species of Mimosa in Mexico, especially from the central highlands where Mimosa spp. have diversified. Nodules were tested for betaproteobacteria using in situ immunolocalization. Rhizobia isolated from the nodules were genetically characterized and tested for their ability to nodulate Mimosa spp. Immunological analysis of 25 host taxa suggested that most (including all the highland endemics) were not nodulated by betaproteobacteria. Phylogenetic analyses of 16S rRNA, recA, nodA, nodC and nifH genes from 87 strains isolated from 20 taxa confirmed that the endemic Mexican Mimosa species favoured alphaproteobacteria in the genera Rhizobium and Ensifer: this was confirmed by nodulation tests. Host phylogeny, geographic isolation and coevolution with symbionts derived from very different soils have potentially contributed to the striking difference in the choice of symbiotic partners by Mexican and Brazilian Mimosa species.

  5. Studies on bilharziasis endemicity in the vicinity of Basra, Iraq*

    Najarian, H. H.; de Araoz, J.; Klimt, C. R.; al Ani, K.; Azzawi, J.

    1961-01-01

    This paper reports on investigations into the distribution of snail genera and possible limiting environmental factors in the endemic and non-endemic areas of human bilharziasis in and near Basra, carried out in 1958 by the WHO Bilharziasis Control Project staff in Iraq. These investigations confirmed the existence of an abrupt line of demarcation between these areas immediately south of Basra. During June and October 1958, the known intermediate snail host, Bulinus truncatus, was not found in canals bordering on areas of either infected or non-infected human populations. From these findings and the evidence of previous investigations it is concluded that in southern Iraq, and particularly in Basra, B. truncatus has been demonstrated with difficulty, if at all. Nevertheless, transmission has continued to take place. Explanations of this apparent phenomenon are discussed and it is concluded that populations of B. truncatus may be completely absent for several years and that other snail genera may play a role in transmitting the disease. A study of environmental factors indicates that water velocities, salinity, turbidity, and pH in the endemic and non-endemic areas showed no significant differences, but that the continuous change in water flow may be a factor limiting B. truncatus colonization. It is also concluded that the salinity in the Shatt al Arab River originates from Lake Hammar and is not introduced from the Persian Gulf by tidal wave, as has been previously believed.

  6. Trichomonad infection in endemic and introduced columbids in the Seychelles.

    Bunbury, N

    2011-07-01

    Island endemic avifaunas face many threats, including the now well-documented impacts of pathogens. The impacts of pathogens on the endemic Seychelles avifauna, however, have been little studied. The protozoan parasite Trichomonas gallinae has been shown to reduce survival and reproductive success of the endemic Pink Pigeon Columba mayeri on the nearby island of Mauritius. I investigated trichomonad infection prevalence and pathogenicity in endemic Seychelles Blue Pigeons, Alectroenas pulcherrima, and two introduced species of columbid, the Madagascar Turtle-dove, Streptopelia picturata, and the Barred Ground Dove, Geopelia striata, on the Seychelles island of Mahé during September-October 2007. I asked whether: 1) trichomonad infections occur in these species; 2) prevalence varies among species; and 3) birds show any signs of pathogenicity consistent with tricho-monosis. I use the results to assess the potential threat of this pathogen to A. pulcherrima. All three species were infected with trichomonads, and the overall prevalence was 27.5%. Alectroenas pulcherrima had higher prevalence (47.1%) than the two introduced species combined (24.3%). No infected individuals showed any signs of disease. These findings suggest that trichomonad parasites should be considered as a potential disease threat to the A. pulcherrima population. PMID:21719842

  7. Future of endemic flora of biodiversity hotspots in India.

    Vishwas Sudhir Chitale

    Full Text Available India is one of the 12 mega biodiversity countries of the world, which represents 11% of world's flora in about 2.4% of global land mass. Approximately 28% of the total Indian flora and 33% of angiosperms occurring in India are endemic. Higher human population density in biodiversity hotspots in India puts undue pressure on these sensitive eco-regions. In the present study, we predict the future distribution of 637 endemic plant species from three biodiversity hotspots in India; Himalaya, Western Ghats, Indo-Burma, based on A1B scenario for year 2050 and 2080. We develop individual variable based models as well as mixed models in MaxEnt by combining ten least co-related bioclimatic variables, two disturbance variables and one physiography variable as predictor variables. The projected changes suggest that the endemic flora will be adversely impacted, even under such a moderate climate scenario. The future distribution is predicted to shift in northern and north-eastern direction in Himalaya and Indo-Burma, while in southern and south-western direction in Western Ghats, due to cooler climatic conditions in these regions. In the future distribution of endemic plants, we observe a significant shift and reduction in the distribution range compared to the present distribution. The model predicts a 23.99% range reduction and a 7.70% range expansion in future distribution by 2050, while a 41.34% range reduction and a 24.10% range expansion by 2080. Integration of disturbance and physiography variables along with bioclimatic variables in the models improved the prediction accuracy. Mixed models provide most accurate results for most of the combinations of climatic and non-climatic variables as compared to individual variable based models. We conclude that a regions with cooler climates and higher moisture availability could serve as refugia for endemic plants in future climatic conditions; b mixed models provide more accurate results, compared to single

  8. Sequence Characterization of Mitochondrial 12S rRNA Gene in Mouse Deer (Moschiola indica for PCR-RFLP Based Species Identification

    2013-01-01

    Full Text Available Mitochondrial 12S rRNA has proven to be a useful molecular marker for better conservation and management of the endangered species. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP of the mitochondrial 12S rRNA gene has proven to be a reliable and efficient tool for the identification of different Indian deer species of family cervidae. In the present study, mitochondrial 12S rRNA gene sequence of mouse deer (Moschiola indica belonging to the family Tragulidae was characterized and analysed in silico for its use in species identification. Genomic DNA was isolated from the hair follicles and mitochondrial 12S rRNA gene was amplified using universal primers. PCR product was cloned and sequenced for the first time. The sequence of mouse deer showed 90.04, 90.08, 90.04, 91.2, 90.04, and 90.08% identities with sika deer, sambar, hog deer, musk deer, chital, and barking deer, respectively. Restriction mapping in Lasergene (DNAstar Inc., Madison, WI, USA revealed that mouse deer mitochondrial 12S rRNA gene sequence can be differentiated from the other deer species in PCR-RFLP using RsaI, DdeI, BsrI, and BstSFI. With the help of predicted pattern, mouse deer can be identified using genomic DNA from a variety of biomaterials, thereby providing molecular aid in wildlife forensics and conservation of the species.

  9. The pCS20 PCR assay for Ehrlichia ruminantium does not cross-react with the novel deer ehrlichial agent found in white-tailed deer in the United States of America

    White-tailed deer are susceptible to heartwater (Ehrlichia [Cowdria] ruminantium infection) and are likely to suffer high mortality if the disease spreads to the United States. It is vital, therefore, to validate a highly specific and sensitive detection method for E. ruminantium infection that can be reliably used in testing white-tailed deer, which are reservoirs of antigenically or genetically related agents such as Ehrlichia chaffeensis, Anaplasma (Ehrlichia) phagocytophilum (HGE a...

  14. Plant community and white-tailed deer nutritional carrying capacity response to intercropping switchgrass in loblolly pine plantations

    Greene, Ethan Jacob

    Switchgrass (Panicum virgatum L.) is a cellulosic feedstock for alternative energy production that could grow well between planted pines (Pinus spp.). Southeastern planted pine occupies 15.8 million hectares and thus, switchgrass intercropping could affect biodiversity if broadly implemented. Therefore, I evaluated effects of intercropping switchgrass in loblolly pine (P. taeda L.) plantations on plant community diversity, plant biomass production, and white-tailed deer (Odocoileus virginianus Zimmerman) nutritional carrying capacity. In a randomized complete block design, I assigned three treatments (switchgrass intercropped, switchgrass monoculture, and a "control" of traditional pine management) to 4 replicates of 10-ha experimental units in Kemper County, Mississippi during 2014-2015. I detected 246 different plant species. Switchgrass intercropping reduced plant species richness and diversity but maintained evenness. I observed reduced forb and high-use deer forage biomass but only in intercropped alleys (interbeds). Soil micronutrient interactions affected forage protein of deer plants. White-tailed deer nutritional carrying capacity remained unaffected.

  15. Drought effect on selection of conservation reserve program grasslands by white-tailed deer on the Northern Great Plains

    Limited information exists regarding summer resource selection of white-tailed deer (Odocoileus virginianus) in grassland regions of the Northern Great Plains. During summers 2005-2006, we analyzed habitat selection of adult female white-tailed deer in north-central South Dakota. We collected 1905 summer locations and used 21 and 30 home ranges during 2005 and 2006, respectively, to estimate habitat selection. Results indicated that selection occurred at the population (P drought conditions during 2006. Deer likely selected for fields of CRP grasslands during early summer for cover and natural forages, such as clover (Trifolium sp.), prior to the period when agricultural crops become available. Drought conditions occurring in semiarid prairie grassland regions may reduce food and water availability and contribute to subsequent changes in deer habitat selection across the range of the species.

  19. Prevalence and molecular analyses of hemotrophic Mycoplasma spp. (hemoplasmas) detected in sika deer (Cervus nippon yesoensis) in Japan.

    Tagawa, Michihito; Matsumoto, Kotaro; Yokoyama, Naoaki; Inokuma, Hisashi

    2014-03-01

    Hemotropic mycoplasmas (hemoplasmas) are cell-wall deficient, epierythrocytic bacteria that cause infectious anemia in several mammalian species. The prevalence of hemoplasma species was examined by screening and species-specific PCR using blood samples collected from 51 sika deer in Hokkaido, Japan. Molecular analyses were performed for the 16S rRNA, 23S rRNA and RNase P RNA (rnpB) gene sequences. A total of 23/51 (45%) deer DNA samples were positive for hemoplasmas in the screening PCR. Using species-specific PCR, 12 and 17 samples were positive for 'Candidatus Mycoplasma haemocervae' and 'Candidatus M. erythrocervae', respectively. Sequencing and phylogenetic trees of those three genes indicate that the 'Candidatus M. haemocervae' and 'Candidatus M. erythrocervae' detected in Japanese deer are potentially different species from the cervine hemoplasma found in deer from America and Brazil.

    This work demonstrates the feasibility of making sensitive nanometer distance measurements between Fe(III) heme centers and nitroxide spin labels in proteins using the double electron-electron resonance (DEER) pulsed EPR technique at 94 GHz. Techniques to measure accurately long distances in many classes of heme proteins using DEER are currently strongly limited by sensitivity. In this paper we demonstrate sensitivity gains of more than 30 times compared with previous lower frequency (X-band) DEER measurements on both human neuroglobin and sperm whale myoglobin. This is achieved by taking advantage of recent instrumental advances, employing wideband excitation techniques based on composite pulses and exploiting more favorable relaxation properties of low-spin Fe(III) in high magnetic fields. This gain in sensitivity potentially allows the DEER technique to be routinely used as a sensitive probe of structure and conformation in the large number of heme and many other metalloproteins.

  1. Rusa deer (Cervus timorensis) as a host for the cattle tick (Boophilus microplus) in Papua New Guinea.

    Owen, I L

    1977-04-01

    The rusa deer (Cervus timorensis) is more resistant to the cattle tick (Boophlilus microplus) than are Britsh breed cattle in Papua New Guinea. The average yield of replete female ticks from deer was 1.6% (0.3-3.2%) as compared to 11.2% (3.4-23.1%) from calves. Ticks from deer were more slender, lighter in weight and produced fewer eggs (mean 1,800) than did ticks from calves (mean 2,200) but the deer was shown to be an effective host. A cervid population can maintain a tick population in the absence of bovine hosts thus presenting an important factor in eradication programs. Nutritional stress appears to result in a higher seasonal prevalence of infestation amongst males and non-pregnant females. PMID:864854

    2016-04-01

    Orally delivered mycobacterial antigens may not sensitize the immunized animals causing a positive tuberculin skin test response. As the first step to address this critical issue, we characterized the response of farmed red deer (Cervus elaphus) to orally delivered heat-inactivated Mycobacterium bovis. Thirty-two adult red deer hinds from a farm known to be free of tuberculosis (TB) were randomly assigned to two different treatment groups, immunized (n=24) and control (n=8). Immunized hinds were dosed orally with 2ml of PBS containing 6×10(6) heat-inactivated M. bovis. The mean skin test response of immunized deer to both avian purified protein derivative (aPPD) and bovine PPD (bPPD) was consistently lower in immunized than in control hinds. One year after immunization, immunized hinds had a significant reduction in the skin test response to aPPD and in the ELISA antibody levels against both aPPD and bPPD (24-36% reduction; Ptest response to phytohaemagglutinin, or in the ELISA antibody levels against the M. bovis specific antigen MPB70. The mRNA levels for C3, IFN-γ and IL-1β and serum protein levels for IFN-γ and IL-1β did not vary between immunized and control deer. However, serum C3 protein levels were significantly higher (P=0.001) in immunized than in control deer six months after immunization. These results confirm that oral heat-inactivated M. bovis does not sensitize farmed red deer and therefore does not cause false-positive responses in the tuberculin skin test. The absence of sensitization in orally immunized deer opens the possibility of testing the vaccine in deer and possibly other ruminants without the risk of causing false-positive reactions in TB-tests. This study also provided the first evidence that orally-delivered inactivated mycobacterial antigens elicit some kind of immune response in a ruminant. PMID:27032499

    Substantial evidence for prion transmission via blood transfusion exists for many transmissible spongiform encephalopathy (TSE) diseases. Determining which cell phenotype(s) is responsible for trafficking infectivity has important implications for our understanding of the dissemination of prions, as well as their detection and elimination from blood products. We used bioassay studies of native white-tailed deer and transgenic cervidized mice to determine (i) if chronic wasting disease (CWD) blood infectivity is associated with the cellular versus the cell-free/plasma fraction of blood and (ii) in particular if B-cell (MAb 2-104(+)), platelet (CD41/61(+)), or CD14(+) monocyte blood cell phenotypes harbor infectious prions. All four deer transfused with the blood mononuclear cell fraction from CWD(+) donor deer became PrP(CWD) positive by 19 months postinoculation, whereas none of the four deer inoculated with cell-free plasma from the same source developed prion infection. All four of the deer injected with B cells and three of four deer receiving platelets from CWD(+) donor deer became PrP(CWD) positive in as little as 6 months postinoculation, whereas none of the four deer receiving blood CD14(+) monocytes developed evidence of CWD infection (immunohistochemistry and Western blot analysis) after 19 months of observation. Results of the Tg(CerPrP) mouse bioassays mirrored those of the native cervid host. These results indicate that CWD blood infectivity is cell associated and suggest a significant role for B cells and platelets in trafficking CWD infectivity in vivo and support earlier tissue-based studies associating putative follicular B cells with PrP(CWD). Localization of CWD infectivity with leukocyte subpopulations may aid in enhancing the sensitivity of blood-based diagnostic assays for CWD and other TSEs. PMID:20219916

    Mating signals can be used both in contexts of species recognition and mate quality assessment. This study examines species recognition abilities in oestrous females presented with male mating calls from both conspecifics and closely related allopatric heterospecifics. Red deer and sika deer are naturally allopatric polygynous species capable of hybridization during sympatry. Male mating calls are sexually selected and differ greatly between species. Previous work indicated that most but not ...

  6. Hybridisation and introgression of exotic Cervus (nippon and canadensis) with red deer (Cervus elaphus) in the British Isles

    2013-01-01

    Europe’s largest population of wild red deer (Cervus elaphus) resides in the British Isles and has been present since the end of the last ice age, c. 11,000BP. Since the mid-19th century, multiple introductions of Japanese sika (Cervus nippon) and wapiti (Cervus canadensis) have taken place across the British Isles. While wapiti introductions have generally gone extinct, sika have thrived and expanded and now often live in sympatry with red deer. Hybridisation between these spe...

    To address Sin Nombre (SN) virus persistence in deer mice, we sacrificed experimentally infected deer mice at eight time points from day 21 to day 217 postinoculation (p.i.) and examined their tissues for viral nucleocapsid (N) antigen expression and both negative-strand (genomic) and positive-strand (replicative/mRNA) viral S segment RNA titers. All the animals that we inoculated developed persistent infections, and SN virus could be isolated from tissues throughout the course of infection. ...

  10. Long-term regional shifts in plant community composition are largely explained by local deer impact experiments.

    Frerker, Katie; Sabo, Autumn; Waller, Donald

    2014-01-01

    The fact that herbivores and predators exert top-down effects to alter community composition and dynamics at lower trophic levels is no longer controversial, yet we still lack evidence of the full nature, extent, and longer-term effects of these impacts. Here, we use results from a set of replicated experiments on the local impacts of white-tailed deer to evaluate the extent to which such impacts could account for half-century shifts in forest plant communities across the upper Midwest, USA. We measured species' responses to deer at four sites using 10-20 year-old deer exclosures. Among common species, eight were more abundant outside the exclosures, seven were commoner inside, and 16 had similar abundances in- and outside. Deer herbivory greatly increased the abundance of ferns and graminoids and doubled the abundance of exotic plants. In contrast, deer greatly reduced tree regeneration, shrub cover (100-200 fold in two species), plant height, plant reproduction, and the abundance of forbs. None of 36 focal species increased in reproduction or grew taller in the presence of deer, contrary to expectations. We compared these results to data on 50-year regional shifts in species abundances across 62 sites. The effects of herbivory by white-tailed deer accurately account for many of the long-term regional shifts observed in species' abundances (R2 = 0.41). These results support the conjecture that deer impacts have driven many of the regional shifts in forest understory cover and composition observed in recent decades. Our ability to link results from shorter-term, local experiments to regional long-term studies of ecological change strengthens the inferences we can draw from both approaches. PMID:25551827

  11. Impacts of deer herbivory on vegetation in Rock Creek Park, 2001-2009

    Kraft, Cairn C.; Hatfield, Jeff S.

    2011-01-01

    Starting in 2001, vegetation data have been collected annually in 16 study modules consisting of paired (1x4 m) fenced plots and unfenced control plots located in the upland forests of Rock Creek Park, Washington, D.C. Vegetation data collected from 2001-2009 have been analyzed to determine impacts of deer herbivory on vegetation in the park. Differences between fenced plots and unfenced control plots were analyzed for the following variables: cover provided by various groups of species (woody, herbaceous, native, non-native, trees, shrubs, and woody vines), as well as by individual dominant species, vegetation thickness (a measure of percent cover projected horizontally that provides information on the vertical distribution of vegetation), and species richness overall and for groups of species (woody, herbaceous, native, non-native, trees, shrubs, and woody vines). The analyses were performed using repeated measures analysis of variance (ANOVA) and associated tests. Vegetation in plots protected from deer herbivory for 9 years showed significantly greater vegetative cover compared to plots not protected from deer herbivory. This effect was most pronounced for woody and shrub cover. Cover by the dominant species was not significantly greater in the fenced plots compared to the unfenced control plots, indicating that the significant differences observed for groups were not driven by single species within those groups. With respect to vegetation thickness, results indicate that protection from deer herbivory produced significantly higher levels of vegetation in the fenced plots compared to the unfenced control plots for both the Low (0-30 cm) and Middle (30-110 cm) height classes. Protection from deer herbivory has led to higher overall species richness and higher species richness for woody species, natives, and shrubs compared to plots not receiving protection. There is also evidence that plots protected from deer herbivory and those not receiving this protection

  13. Evolution of habitat and environment of deer during the Late-glacial and early Holocene: the case of red deer in French Jura.

    Drucker, Dorothée.; Bridault, Anne; Hujic, Alisa; Bocherens, Hervé

    2010-05-01

    The Late-glacial and early Holocene transition is a key period of environmental changes in a context of to a global warming. In northwestern Europe, extensive studies have documented the vegetation and faunal recomposition with the replacement of the cold steppe-tundra ecosystem by the forested temperate ecosystem we can still observe. Paleoecological interest focused on the extinct large mammals species like the Mammoth. In comparison, little has been done to decipher the ecological adaptation of the surviving species, especially those that are still present in the very same region than in the past. A better knowledge of the impact of changing environmental conditions on the ecology would be useful to define the degree of selective pressure. Thus, we have studied the habitat and environment evolution of red deer (Cervus elaphus) during the Late-glacial and early Holocene using stable isotopes and radiocarbon investigations. The analyzed bone material was selected from archaeological sites in French Jura. Performing direct radiocarbon dating on the bone collagen of the selected remains solved the problem of possible chronological uncertainties of the stratigraphical record of the sites. The same bone collagen samples were used for stable isotope measurements. We investigated the relative abundances in 13C to examine changes in habitat closure (canopy effect), in 15N to decipher changes in pedogenic activities (soil maturation) of the animals dwelling, and in 18O to track changes in altitude and/or local temperatures of the occupied territories. The results demonstrate that the stable isotopic composition of red deer bone collagen can be a valuable and sensitive indicator of habitat use and environmental conditions. The associated direct dating allows us to reconstruct the chronology of ecological changes. The combined chronological and ecological results evidence local differences in red deer adaptation at a small geographical scale.

  14. Lesion Distribution and Epidemiology of Mycobacterium bovis in Elk and White-Tailed Deer in South-Western Manitoba, Canada

    Todd K. Shury

    2011-01-01

    Full Text Available Surveillance for Mycobacterium bovis in free-ranging elk (Cervus elaphus and white-tailed deer (Odocoileus virginianus from south-western Manitoba was carried out from 1997 to 2010 to describe the lesions, epidemiology, and geographic distribution of disease. Tissues were cultured from animals killed by hunters, culled for management, blood-tested, or found opportunistically. Period prevalence in elk was approximately six times higher than deer, suggesting a significant reservoir role for elk, but that infected deer may also be involved. Prevalence was consistently higher in elk compared to deer in a small core area and prevalence declines since 2003 are likely due to a combination of management factors instituted during that time. Older age classes and animals sampled from the core area were at significantly higher risk of being culture positive. Positive elk and deer were more likely to be found through blood testing, opportunistic surveillance, and culling compared to hunting. No non-lesioned, culture-positive elk were detected in this study compared to previous studies in red deer.

    2003-03-01

    Three female sika deer from a single captive herd were submitted for postmortem examination over a 139-day period. The first 2 deer submitted were reported to have lost body mass for 20 days to 1 month before euthanasia. One of these deer had diarrhea, the other had a crusting dermatitis on the nasal planum and inner aspects of both pinnae. The third hind did not have any signs of disease before it was found seizuring and was immediately euthanatized. Microscopically, all 3 animals had a lymphocytic vasculitis typical of malignant catarrhal fever (MCF), with the most severe lesions in the brain. All 3 deer were polymerase chain reaction (PCR) positive for caprine herpesvirus 2 (CpHV-2) and were negative for ovine herpesvirus 2 (OHV-2). Two healthy goats that were housed adjacent to the deer were also PCR positive for CpHV-2 and PCR negative for OHV-2. The CpHV-2, PCR amplicons from the hinds, and the 2 healthy goats had an identical single base polymorphism. A male sika deer that was housed with the hinds and a fawn from 1 of the hinds remained asymptomatic and were PCR negative for CpHV-2. This represents the first report of mortality with MCF-like lesions in association with CpHV-2. PMID:12661731

  16. Changes during the holocene in the size of white-tailed deer ( Odocoileus virginianus) from central Illinois

    Purdue, James R.

    1989-11-01

    White-tailed deer ( Odocoileus virginianus) from central Illinois varied in size during the Holocene. The record, which extends back to 8450 yr B.P., indicates small deer through the mid-Holocene until 3650 yr B.P., after which size increases. Although influences of winter climate, seasonality, anthropogenic effects, and other ecological factors should not be discounted, an intriguing possible cause of the deer size shifts is insolation-driven summer climate and its influence on food resources. In the Holocene, small deer size is correlated with high summer insolation and with low winter insolation. Climatic models indicate that in spite of changes in insolation, Holocene winters did not vary greatly through time, especially in contrast to summers, which were dynamic. Physiological constraints peculiar to O. virginianus make critical the quality of summer forage for determining final adult size. Summer temperature averaged 2°C warmer than present during the middle Holocene, which increased evaporation and probably reduced the period of availability of high-quality forage low in fiber and high in protein. Consequently, less fuel for growth was consumed by mid-Holocene deer and only small body size was achieved. Other possible causes (e.g., Bergmann's rule, seasonality) of clinal variation are considered with reference to central Illinois deer, but at present the most parsimonious explanation appears to be the summer insolation hypothesis.

  17. Cadmium accumulation in deer tongue grass (Panicum clandestinum L.) and potential for trophic transfer to microtine rodents

    Site 36 at the Crab Orchard National Wildlife Refuge includes a Cd-contaminated soil dominated by deer tongue grass (Panicum clandestinum L.). Analysis of deer tongue grass from this site indicated that biomass and leaf surface area were reduced and that there was a linear relationship between both plant bioavailable soil Cd and total soil Zn and tissue Cd concentration. The Cd concentrations in stems and leaves were also used to estimate the dietary Cd exposures that might be experienced by prairie voles (Microtus ochrogaster) and pine voles (M. pinetorum) consuming deer tongue grass. Renal and hepatic Cd burdens predicted from exclusive consumption of deer tongue grass would be comparable to those that have resulted in chronic toxicity in rodents. The results suggest that for the contaminated soil at Site 36, conditions could allow for the accumulation of Cd in deer tongue grass to concentrations that may pose an ecological risk. - Deer tongue grass growing on a Cd-contaminated site accumulated Cd to concentrations that would be potentially toxic to microtine rodents using this plant as an exclusive food source

    2016-03-01

    Numerous species of Sarcocystis have been reported from wild ruminants, but none has been from Williamson's mouse deer (Tuagulus williamsoni). Here, we describe a new species, Sarcocystis tuagulusi, infecting five of 12 Williamson's mouse deer from southwest China. Mature sarcocysts are microscopic, up to 2280-μm long. The sarcocyst wall had 8.2-μm long villar protrusions, type 24. Using transmission electron microscopy, the protrusions on sarcocysts appeared as elongated, lancet- or leaf-like shapes in longitudinal sections; in contrast, the cross-sections revealed mushroom-shaped protrusions. In the core of the protrusion, a bundle of microtubules penetrated diagonally into a ground substance along the longitudinal axis. A phyogenetic analysis based on 18S rRNA and cox1 sequences suggested S. tuagulusi is closely related to Sarcocystis species from ruminants that employ felids as definitive hosts. PMID:26677097

  20. Location analysis and strontium-90 concentrations in deer antlers on the Hanford Site

    The primary objective of this study was to examine the levels of strontium-90 (90Sr) in deer antlers collected from near previously active reactor sites and distant from the reactor sites along that portion of the Columbia River which borders the Hanford Site. A second objective was to analyze the movements and home-ranges of mule deer residing within these areas and determine to what extent this information contributes to the observed 90Sr concentrations. 90Sr is a long-lived radionuclide (29.1 year half life) produced by fission in irradiated fuel in plutonium production reactors on the Hanford Site. It is also a major component of atmospheric fallout from weapons testing. Concentrations of radionuclides found in the developed environment onsite do not pose a health concern to humans or various wildlife routinely monitored. However, elevated levels of radionuclides in found biota may indicate routes of exposure requiring attention

  1. Feeding of roe deer (Capreolus capreolus L.) in the exclusion zone of the Chernobyl accident

    Seasonal feed choice of a roe deer for a 3-year period has been investigated on the basis of the rumen content analysis. Results of the investigation are given. A list of 125 species of forage plants is presented. Seasonal intensity of their consumption is characterized. Significance of main plant assemblages of the evacuated zone of Chernobyl in the diet of the animal population is elucidated. Special attention is paid to the role of the above-ground parts of Oenotera biennis that comprise 34% of the average annual forage of roe deer and are consumed by the animal during 9-10 months. Recent state of the forage base of the population is estimated. An attempt to predict its dynamics for the nearest 10-15 years is made

  2. Intestinal adenocarcinoma in a herd of farmed Sika deer (Cervus nippon): a novel syndrome.

    Kelly, P A; Toolan, D; Jahns, H

    2015-01-01

    Intestinal adenocarcinomas were identified in 76 adult deer from a closed herd of 193 breeding animals grazing pasture heavily infested with bracken fern (Pteridium aquilinum). Tumors were observed postmortem in 32 animals with rapid weight loss, and similar neoplasms were detected in a further 44 clinically normal deer at "cull." Tumors were located in distal ileum, cecum, and proximal colon and presented as single (26%) or multiple (74%), variably sized, pale-gray, firm, poorly circumscribed neoplasms with associated intestinal strictures. Histopathologically tumors were well-differentiated, locally infiltrative, low-grade adenocarcinomas of tubular (51%), mucinous (33.5%), or mixed (15.5%) types. Extraintestinal metastases were not observed. The high incidence of intestinal adenocarcinoma within this herd suggests a specific and novel syndrome, and genetic and/or environmental factors may be involved in the pathogenesis. PMID:24503440

  3. Host-Seeking Behavior of Trombiculid Mites on Vegetation in Relation to Sika Deer.

    Tsunoda, Takashi; Takahashi, Mamoru

    2015-03-01

    We collected larval trombiculid mites on vegetation monthly from October 1997 to February 2000, and from the heads of sika deer culled in March 2003 in Boso Peninsula, central Japan. Two species of trombiculid mites, Neotrombicula nogamii Takahashi, Takano, Misumi, and Kikuchi and Leptotrombidium scutellare Nagayo, Miyagawa, Mitamura, and Tamiya, occurred on vegetation. Peak numbers of N. nogamii were found in January, and L. scutellare numbers peaked in November. Both species were collected predominantly on the top of Sasa bamboo stems, where they formed clusters, though N. nogamii preferred heights of 40-50 cm. Furthermore, N. nogamii and Walchia masoni (Asanuma and Saito) were collected from deer. These findings indicate that vegetation is an important substrate for some trombiculid mites awaiting hosts.

  5. Factors affecting road mortality of white-tailed deer in eastern South Dakota

    Grovenburg, Troy W.; Jenks, Jonathan A.; Klaver, Robert W.; Monteith, Kevin L.; Galster, Dwight H.; Schauer, Ron J.; Morlock, Wilbert W.; Delger, Joshua A.

    2008-01-01

    White-tailed deer (Odocoileus virginianus) mortalities (n = 4,433) caused by collisions with automobiles during 2003 were modeled in 35 counties in eastern South Dakota. Seventeen independent variables and 5 independent variable interactions were evaluated to explain deer mortalities. A negative binomial regression model (Ln Y = 1.25 – 0.12 [percentage tree coverage] + 0.0002 [county area] + 5.39 [county hunter success rate] + 0.0023 [vehicle proxy 96–104 km/hr roads], model deviance = 33.43, χ2 = 27.53, df = 27) was chosen using a combination of a priori model selection and AICc. Management options include use of the model to predict road mortalities and to increase the number of hunting licenses, which could result in fewer DVCs.

  6. Electron probe study of human and red deer cementum and root dentin

    A topographical description of the concentration profiles of Ca, P, Mg, Zn, F, S, and K in human and red deer cementum and root dentin is given. The concentrations reported should be regarded as semiquantitative values. A downward slope of the Ca, P, and Mg profiles toward the pulpal cavity seemed largely to correspond with the secondary dentin. Marked elevations of the Zn profiles, modest elevations of the F profiles, and in a few instances of the S profiles, toward root surface and pulpal cavity were registered. In a couple of scans a slight elevation of the K profile toward the root surface was observed. A high degree of concordance in human and red deer teeth was ascertained. (author)

  8. Malignant catarrhal fever in farmed Rusa deer (Cervus timorensis). 2. Animal transmission and virological studies.

    Westbury, H A; Denholm, L J

    1982-03-01

    A disease with clinical signs and histological lesions similar to malignant catarrhal fever in cattle was transmitted from Rusa deer (Cervus timorensis) to rabbits. This was accomplished on 3 separate occasions, and the disease was serially passaged in rabbits up to 11 times. The clinical signs in affected rabbits were pyrexia, depression, anorexia, mucopurulent conjunctivitis, nasal discharge and diarrhoea. These signs were seen in 27 of 38 inoculated rabbits with the mean incubation period being 12 days (range 8 to 20 days). Histologically, affected rabbits exhibited mononuclear perivascular cuffing and vasculitis in the brain, heart, liver and kidney. Lymph nodes and spleen showed destruction and loss of mature lymphocytes and lymphoid follicles and an increased number of large lymphoblastoid cells. These clinical signs and lesions were not detected in control rabbits. The disease was not transmitted to cattle, sheep, guinea pigs or mice, nor was an agent isolated in cattle, deer or rabbit tissue cultures, or in chicken embryos. PMID:7115234

  9. Campylobacter hyointestinalis-associated enteritis in Moluccan rusa deer (Cervus timorensis subsp. Moluccensis).

    Hill, B D; Thomas, R J; Mackenzie, A R

    1987-11-01

    A morphological and bacteriological study on a Campylobacter hyointestinalis-associated enteritis in adult Moluccan rusa deer is described. Necropsied deer were 2 to 2.5 years of age and had been scouring for 1 to 2 months. There was distension of the ileum and excessive corrugation of the mucosa. Microscopic lesions in the small intestine were confined to the ileum. Stunting and fusion of villi, patchy erosion of epithelium and a predominantly neutrophilic infiltrate were features. The inflammatory reaction in caecum and colon was much less severe. Light and scanning electron-microscopical examination of small and large intestine showed large numbers of Gram-negative curved rods colonizing surface mucus and moderate numbers in close association with gland epithelium. No salmonellae or other enteropathogenic bacteria were isolated on aerobically-incubated media. C. hyointestinalis was isolated from the faeces, ileum, caecum, colon and mesenteric lymph nodes from 2 cases and one farm-collected faecal sample. PMID:3443691

  10. An outbreak of malignant catarrhal fever in young rusa deer (Cervus timorensis).

    Tomkins, N W; Jonsson, N N; Young, M P; Gordon, A N; McColl, K A

    1997-10-01

    On the basis of clinical signs and histological findings eight 9-month-old male rusa deer (Cervus timorensis) were diagnosed with sheep associated-malignant catarrhal fever. Following a variable course involving rectal temperatures around 40.5 degrees C, depression, inappetence, diarrhoea, corneal opacity and hypopyon all animals died or were euthanased over a 5-week period. Severe multifocal vasculitis, mainly periglomerular and in the arcuate vessels were consistent histological findings which in the past have been adequate to confirm clinical diagnosis of sheep associated-malignant catarrhal fever. A nested polymerase chain reaction test has been used to detect a sheep associated-malignant catarrhal fever PRC product, 238 base-pairs in size, in DNA extracted from lymphocyte preparations. The result supported the diagnosis of sheep associated-malignant catarrhal fever in these deer. PMID:9406629

  11. Pre-orbital gland opening during aggressive interactions in rusa deer (Rusa timorensis).

    Ceacero, Francisco; Pluháček, Jan; Komárková, Martina; Zábranský, Martin

    2015-02-01

    The opening of the preorbital gland in cervids has a visual meaning and is frequently associated with agonistic and/or stress related situations. Apart from in red deer, this behaviour has scarcely been studied and the range of situations when it may occur remains unclear. In this study we report the unusual case of preorbital gland opening in rusa deer, Rusa timorensis, associated to direct aggressive agonistic interaction (biting/kicking) between two adult hinds. This case observed in Tierpark Berlin (Germany) is the first one ever recorded in female-female interactions in cervids. Preorbital gland opening was also studied in 116 social interactions in Plzeň Zoo (Czech Republic). Preorbital gland opening by the dominant adult male was twice observed with relation to alert behaviour, which is also rare. In order to contextualise our observations we summarise the current knowledge about the behaviour associated with preorbital gland opening in R. timorensis and in cervids in general. PMID:25481309

  12. Responses to TRH in patients with endemic goiter

    The response to TRH was studied in 32 patients from an endemic goiter area, 20 of them had been previously treated with iodized oil. Blood samples were taken at 0, 20, 40 and 120 minutes after de i.v. administration of 400μg of TRH, and serum levels of TSH, T3 and T4 were measured. The results obtained show that in endemic goiter area there is a modification in the hypothalamus-pituitary-thyroid feedback mechanism, with increased reserve of pituitary TSH and changes in T4 and T3 secretion. The injection of TRH gave exaggerated and delayed responses in the secretion of TSH and T3. Iodized oil used as a prophylatic method produced a disminution of pituitary TSH reserve, and of serum levels of TSH and T3, as a result of the return tonormality of the hypothalamus-pituitary-thyroid feedback mechanism.

    2012-01-01

    In the present study, the presence of the phloroglucinol derivative hyperforin, the naphthodianthrones hypericin and pseudohypericin, the phenylpropane chlorogenic acid and the flavonoids rutin, hyperoside, kaempferol, isoquercetine, quercitrine, and quercetine was investigated in Hypericum leptophyllum Hochst., an endemic Turkish species for the first time. The aerial parts representing a total of 30 individuals were collected at full flowering and dissected into floral, leaf, and stem tissues. After being dried at room temperature, the plant materials were assayed for secondary metabolite concentrations by HPLC. Aerial plant parts accumulated chlorogenic acid, hyperoside, isoquercetine, quercitrine, and quercetine, but they did not accumulate hyperforin, hypericin, pseudohypericin, rutin, and kaempferol. Accumulation levels of the detected compounds varied with plant tissues. Such kind of data could be useful for elucidation of the chemotaxonomical significance of the corresponding compounds and phytochemical evaluation of this endemic species. PMID:22649295

  14. Mapping phylogenetic endemism in R using georeferenced branch extents

    Guerin, Greg R.; Lowe, Andrew J.

    2015-12-01

    Applications are needed to map biodiversity from large-scale species occurrence datasets whilst seamlessly integrating with existing functions in R. Phylogenetic endemism (PE) is a biodiversity measure based on range-restricted phylogenetic diversity (PD). Current implementations use area of occupancy (AOO) or frequency to estimate the spatial range of branch-length (i.e. phylogenetic range-rarity), rather than extent of occurrence (EOO; i.e. georeferenced phylogenetic endemism), which is known to produce different range estimates. We present R functions to map PD or PE weighted by AOO or EOO (new georeferenced implementation), taking as inputs georeferenced species occurrences and a phylogeny. Non-parametric statistics distinguish PD/PE from trivial correlates of species richness and sampling intensity.

  15. Deforestation and apparent extinctions of endemic forest beetles in Madagascar.

    Hanski, Ilkka; Koivulehto, Helena; Cameron, Alison; Rahagalala, Pierre

    2007-06-22

    Madagascar has lost about half of its forest cover since 1953 with much regional variation, for instance most of the coastal lowland forests have been cleared. We sampled the endemic forest-dwelling Helictopleurini dung beetles across Madagascar during 2002-2006. Our samples include 29 of the 51 previously known species for which locality information is available. The most significant factor explaining apparent extinctions (species not collected by us) is forest loss within the historical range of the focal species, suggesting that deforestation has already caused the extinction, or effective extinction, of a large number of insect species with small geographical ranges, typical for many endemic taxa in Madagascar. Currently, roughly 10% of the original forest cover remains. Species-area considerations suggest that this will allow roughly half of the species to persist. Our results are consistent with this prediction. PMID:17341451

  16. Environmental and human factors affecting spatial behaviour and detectability of roe deer (capreolus capreolus): influence on population estimate

    Bongi, Paolo

    2009-01-01

    This work confirmed one of the most crucial issues of wildlife management, i.e., how it’s difficult to estimate roe deer population density. I checked for different accuracy of roe deer census methods. Census methods were considered according to environmental characteristic, i.e., one of the major factors affecting bias in roe deer density estimation. A strong underestimation was given in the use of the line transect, block count, and spotlight count techniques. Depending on en...

  17. Using improved technology for filter paper-based blood collection to survey wild Sika deer for antibodies to hepatitis E virus

    Yu, Claro; Zimmerman, Carl; Stone, Roger; Engle, Ronald E.; Elkins, William; Nardone, Glenn A.; Emerson, Suzanne U.; Purcell, Robert H.

    2007-01-01

    Recent reports from Japan implicated wild Sika deer (Cervus nippon) in the zoonotic transmission of hepatitis E to humans. Seroprevalence studies were performed to determine if imported feral populations of Sika deer in Maryland and Virginia posed a similar risk of transmitting hepatitis E virus (HEV). Hunters collected blood on filter paper disks from freshly killed deer. The disks were desiccated and delivered to a collection point. The dried filters were weighed to estimate the amount of b...

  18. Vegetation Recovery in Response to the Exclusion of Grazing by Sika Deer (Cervus nippon) in Seminatural Grassland on Mt. Kushigata, Japan

    Nagaike, Takuo; Ohkubo, Eiji; Hirose, Kazuhiro

    2014-01-01

    We examined the recovery of vegetation in seminatural grassland in central Japan after eliminating grazing by sika deer (Cervus nippon) by fencing. By 2012, after 5 years of fencing for exclusion of sika deer, the species composition of quadrats within the enclosure reverted to the original species composition in 1981, not browsed by sika deer. Conversely, outside the fence was different from the baseline quadrats in 1981. Iris sanguinea, a prominent flower in the area, recovered within the e...
