    Many of us think that all wild animals are dangerous. In fact, very few of them will eat a man if he leaves them alone. If you meet a tiger, I'm sure you will run away, but even a tiger doesn't like meeting a man if it isn't hungry. Tigers only kill and eat man when they are too old to catch their food, such as sheep and other small animals. Some animals get frightened when they only smell a man. Some of themst and and look at a man for a short time before they run away.

    Diverse wild animal species can be reservoirs of zoonotic flagellate parasites, which can cause pathologic Chagas disease. The present study aimed to detect the natural occurrence of flagellate parasites through direct microscopic examination of the parasites in blood samples and through PCR of whole blood and blood culture (haemoculture) samples from 38 captive and 65 free-living wild animals in the Centre for Conservation of Wild Fauna (CCWF), an area endemic for leishmaniasis. For this study, PCR was accomplished using primers for the ribosomal region (ITS-1) of the flagellate parasites. The amplified fragments were cloned and sequenced to identify DNA of the Trypanosomatid parasite species, observed in blood cultures from 3.9% (04/103) of the animals. Through these techniques, Trypanosoma cruzi was identified in haemoculture samples of the following three free-living species: common agouti (Dasyprocta aguti), white-eared opossum (Didelphis albiventris), and nine-banded armadillo (Dasypus novemcinctus). Furthermore, Trypanosoma minasense was identified in whole blood samples from 01 (0.9%) captive animal (black howler monkey-Alouatta caraya). These results demonstrated the first report of T. cruzi isolation in wild species from the CCWF using blood culture, which can be applied in addition to molecular tools for epidemiological studies and to identify trypanosomatids in wild animals.

    Wild animal diseases are a global growing concern, given the threat that they pose to animal health and their zoonotic potential. The World Organisation for Animal Health (OIE) was among the first organisations to recognise the importance of having a comprehensive knowledge of the disease situation in wild animals, collecting information on wildlife diseases worldwide since 1993, when for the first time an annual questionnaire was distribute by OIE to members Countries in order to collect qualitative and quantitative data on selected diseases in wild animals. Starting with 2008 until 2012 an updated version of questionnaire was circulated to allow for identifying wildlife species by their Latin name and by their common names in the 3 OIE official languages (English, French, and Spanish). This specific functionality was then implemented in the World Animal Health Information System (WAHIS) in 2012, when this information was made available to the public through WAHIS-Wild Interface.

    Pathogenic Yersinia strains were isolated between December 1998 and April 1999 from 37 wild animals: rabbit (Lepus europeus), boar (Sus scrofa scrofa), asiatic jackal (Canis aureus), red fox (Vulpes vulpes), mouflon (Ovis musimon), european river otter (Lutra lutra), beech marten (Martes foina), polecat (Musleta putorius) and wild cat (Felis silvestris). It was established that among the wild animals Y. enterocolitica strains of serotype 0:3 predominated, accompanied by Y. pseudotuberculosis strains of serotype 0:3. In one sample from asiatic jackal and one sample from rabbit, Y. enterocolitica serotype 0:8 was isolated. Yersinia enterocolitica and Y. pseudotuberculosis strains were isolated from tonsils and tongues as well as from the viscera--lung, liver, heart, spleen, kidney and lymph nodes, mainly in young animals (1-2 years of age). The results showed that wild animals are a possible natural reservoir for pathogenic Y. enterocolitica and Y. pseudotuberculosis and are included in the epidemiological chain of yersinioses.

    1972-07-01

    Lead poisoning was diagnosed post-mortem in 34 simian primates, 11 parrots, and 3 Australian fruit bats at the National Zoological Park. Diagnoses were made by the finding of acid-fast intranuclear inclusion bodies in renal epithelia or hepatocytes and, in most cases, by finding excess lead in samples of liver. The estimated prevalence of lead intoxication among autopsied primates and parrots was 44% and 50% respectively. Leaded paint was found in many animal enclosures at this zoo and it was available to all the lead-poisoned animals in this study. The finding of renal intranuclear inclusion bodies in animals at several zoos, scattered reports of lead intoxication of animals dwelling in various zoos, the occurrence of leaded paint in many zoos and the high incidence of lead poisoning at this zoo, indicated that lead poisoning of zoo animals is much more common than was previously thought.

    2003-01-01

    Many free-ranging wild animals consume significant amounts of tannins and other polyphenolics. Historically, attention has focused on their negative effects: Tannins reduce apparent digestibility, impair the use of absorbed nutrients, can be toxic and reduce the palatability of many forages. Thus, tannins act as feeding deterrants. However, recently the antioxidant and cardioprotective potential of tannins/polyphenolics has been emphasized in human nutrition. Wild animals in captivity are ...

    As a reflection on recent debates on the value of wild animals we examine the question of the intrinsic value of wild animals in both natural and man-made surroundings. We examine the concepts being wild and domesticated. In our approach we consider animals as dependent on their environment, whether it is a human or a natural environment. Stressing this dependence we argue that a distinction can be made between three different interpretations of a wild animal’s intrinsic value: a species-spec...

    2014-01-01

    There is a long history of animal images in literature. What we have known about animal literature is confined into the Greek mythology, Aesop’s Fables and some fairy tales. But in the 20th century, the development of animal literary which focuses on the real animals is great. The Call of the Wild by Jack London is a representative work of describing real animals. This paper will discuss two different images of Buck by means of two archetypes based on Archetype Theory of Carl G. Jung, shadow and hero, in order to study how Buck changed from a dog to a wolf.

    The objective of this study was to investigate the frequency of occurrence and variety of intestinal parasites among free-living wild animals. Fecal samples from wild mammals and birds at rehabilitation centers in the states of Mato Grosso do Sul and São Paulo were analyzed by sedimentation and flotation-centrifugation methods. Parasite eggs, oocysts, cysts and/or trophozoites were found in 71% of the samples. Cryptosporidium sp. oocysts were detected in fecal samples from oncillas (Leopardus tigrinus) and scaly-headed parrots (Pionus maximiliani). Giardia cysts were identified in the feces of a gray brocket (Mazama gouazoubira). Among the most common parasites found, there were eggs from Toxocara cati, Toxascaris leonina and Ancylostoma tubaeforme, and from Cestoda. Several Enterobius sp. eggs were found in the feces of red howler monkeys (Alouatta seniculus). It can be concluded from this study that despite the small number of samples, the diversity of parasites found was noteworthy. Additional information about parasite endofauna in wild animals is needed, since their presence might suggest that there could be proximity to and interactions with domestic animals and/or humans. In addition, further studies on parasites from free-living wild animals are of prime importance for understanding the intensity of anthropic changes in wild environments. PMID:23778826

    Full Text Available Necrophagous Diptera associated with wild animal carcasses in southern Brazil. The aim of this study was to acquire a better knowledge concerning the diversity of necrophagous Diptera that develop on wild animal carcasses. For this purpose, the decomposition of six wild animal carcasses was observed in order to collect and identify the main species of necrophagous flies associated with the decomposition process. The carcasses were found on highways near the cities of Pelotas and Capão do Leão in the initial stage of decomposition, with no significant injuries or prior larval activity. Four wild animal models were represented in this study: two specimens of Didelphis albiventris Lund, 1840; two Tupinambis merianae Linnaeus, 1758; one Nothura maculosa Temminck, 1815; and one Cerdocyon thous Linnaeus, 1766. A total of 16,242 flies from 14 species were reared in the laboratory, where Muscidae presented the greatest diversity of necrophagous species. Overall, (i carcasses with larger biomass developed a higher abundance of flies and (ii the necrophagous community was dominated by Calliphoridae, two patterns that were predicted from published literature; and (iii the highest diversity was observed on the smaller carcasses exposed to the lowest temperatures, a pattern that may have been caused by the absence of the generalist predator Chrysomya albiceps (Wiedemann, 1819. (iv An UPGMA analysis revealed a similar pattern of clusters of fly communities, where the same species were structuring the groupings.

    2010-01-01

    An image-based red blood cell (RBC) automatic counting system is presented for wild animals blood analysis. Images with 2048×1536-pixel resolution acquired on an optical microscope using Neubauer chambers are used to evaluate RBC counting for three animal species (Leopardus pardalis, Cebus apella and Nasua nasua) and the error found using the proposed method is similar to that obtained for inter observer visual counting method, i.e., around 10%. Smaller errors (e.g., 3%) can be obtained in regions with less grid artifacts. These promising results allow the use of the proposed method either as a complete automatic counting tool in laboratories for wild animal's blood analysis or as a first counting stage in a semi-automatic counting tool.

    The zoonotic nematode Trichinella britovi has been documented in animals and/or humans of the Mediterranean islands of Corsica and Sardinia since 2004. From 2005 to 2007 in the Sardinia island, several surveys had shown that T. britovi was circulating among backyard and free-ranging pigs reared in the Orgosolo municipality but all attempts had failed to detect this parasite in wild susceptible animals. The aim of the present work was to investigate the circulation of T. britovi in pigs and wildlife of the Orgosolo municipality, and of surrounding municipalities and provinces in the 2010-2014 slaughtering/hunting seasons. The results show that the T. britovi circulation was still restricted to the Orgosolo municipality with a prevalence of 2.6% in free-ranging pigs and 0.2% in backyard pigs but, for the first time, this parasite was detected also in 0.4% of wild boar, and 27.6% of red foxes. No infection was detected in backyard pigs, wild boar, and red foxes of the other municipalities and provinces. Since 1978, African swine fever is endemic in Sardinia and foci of this virus are still active in the investigated areas favoring cannibalism and, consequently, the T. britovi transmission, due to the high mortality rate caused by this virus. This is the first documented report on the transmission of T. britovi between the domestic and the sylvatic cycle. The health authority of the island must provide a service to dispose animal carcasses and offal, stamping out illegal free-ranging pigs, and train hunters and pig owners to manage waste and by-products according to the EU regulations.

  17. Book review: Fowler's zoo and wild animal medicine (volume 8)

    Sleeman, Jonathan M.

    2014-01-01

    In the eighth volume of Fowler's Zoo and Wild Animal Medicine, the editors have returned to the original, comprehensive, taxa-based format last used in the fifth volume that was released in 2003. The book consists of 82 chapters, divided into taxonomic classes that include amphibians, reptiles, birds, and mammals, and a general topics section. The editors deliberately selected new senior authors who are expert veterinary advisors for the various taxa. This international assemblage of authors is impressive, although the book would have benefited from a greater diversity of disciplinary expertise. Synthesis of the large and expanding body of knowledge about zoo and wild animal medicine is a Sisyphean task, but one that the editors have accomplished well. The chapters were well written and are beautifully illustrated with high-quality images and generally well referenced. Much of the information is summarized in tabular format, which I found both a blessing and a curse. Tabulation of hematologic variables and anesthetic doses is helpful; however, tabulation of information regarding infectious and parasitic diseases results in a loss of detail. For example, methods of diagnosis for some diseases are omitted from some tables. The need for succinctness results in trade-offs, and statements such as “Batrachochytrium dendrobatidis … is one of the most well described pathogens of anurans” with no further information leaves readers unsated. In addition, the book does not have any chapters on fish or invertebrates, which are notable omissions given the importance of these species. Those quibbles aside, this is a must-have book for all zoo and wild animal medicine students and practitioners. However, perhaps it is time to recognize that, during the 36 years since the first volume was published, this discipline has become too large to be contained in 1 book. This is largely because of the success of this book series, and it is a nice problem to have.

  18. Microwave sensors for detection of wild animals during pasture mowing

    Directory of Open Access Journals (Sweden)

    A. Patrovsky

    2005-01-01

    Full Text Available More than 400000 wild animals are killed or severely injured every year during spring time pasture mowing. Conventional methods for detection and removal or expulsion of animals before mowing are either inefficient or very time-consuming. The first really working method is based on a pyro-detector which senses the temperature contrast between the animals body and the surrounding pasture. Unfortunately, the detection reliability of this sensor decreases with increasing ambient temperature and strong sunlight, i.e. for typical weather conditions, when pasture is mowed, especially around noon. In this paper, a detector is presented that exhibits complementary behaviour. It works best during dry conditions (i.e. around noon, but has a tendency to false alarms when dew is present (i.e. morning and evening. The sensor is based on a commercial, low-cost Doppler module at 24GHz. It senses the difference of radar cross section between the animals body (high water content, specular reflection and the pasture (low water content, diffuse reflection. The signal is analysed by means of a non-linear Wigner time-frequency transformation. Experimental results are presented for a laboratory setup as well as for measurement in actual spring-time pasture. The results prove that a microwave sensor is capable of reliably detecting animals of the size of a fawn even if it is covered by a layer of pasture.

  19. Wild Origins: The Evolving Nature of Animal Behavior

    Science.gov (United States)

    Flores, Ifigenia

    For billions of years, evolution has been the driving force behind the incredible range of biodiversity on our planet. Wild Origins is a concept plan for an exhibition at the National Zoo that uses case studies of animal behavior to explain the theory of evolution. Behaviors evolve, just as physical forms do. Understanding natural selection can help us interpret animal behavior and vice-versa. A living collection, digital media, interactives, fossils, and photographs will relay stories of social behavior, sex, navigation and migration, foraging, domestication, and relationships between different species. The informal learning opportunities visitors are offered at the zoo will create a connection with the exhibition's teaching points. Visitors will leave with an understanding and sense of wonder at the evolutionary view of life.

  20. Interactions between environment, wild animals and human leptospirosis

    Directory of Open Access Journals (Sweden)

    LS Ullmann

    2011-01-01

    Full Text Available Leptospirosis, a worldwide distributed zoononis caused by bacteria of the genus Leptospira (antigenically classified into serovars, may be direct or indirectly transmitted through infected urine or environment. Several domestic and wild animals are leptospirosis reservoirs. The disease presents occupational character since it is widely reported in professionals that work in humid environments - such as sewage workers and fishermen - and in places where rodents or susceptible animals are found, like slaughterhouses and veterinary clinics. In developing countries, outbreaks are related to lack of sanitation, overcrowding in inadequate housing and climatic conditions. In developed countries, sporadic cases occur in aquatic recreational activities including swimming and triathlon. The diagnosis of leptospirosis is complex due to the variety of symptoms, disease severity and the lack of techniques that are able to early detect the infection. Thus, leptospirosis causes numerous public health problems and educational activities are very important to its control.

    An outbreak of tuberculosis due to Mycobacterium bovis occurred in a wild animal park. Three pot-bellied pigs (Sus scrofa vittatus), one red deer (Cervus elaphus), one buffalo (Bison bonasus) and two European lynxes (Lynx lynx) were affected and showed clinical signs including weight loss, enlarged lymph nodes and paralysis of the hindlimbs. Postmortem examinations revealed multifocal granulomatous lesions in various organs, including the lymph nodes, lungs, intestines, kidneys and the central nervous system. Acid-fast organisms were demonstrated in various organs histologically and bacteriologically. Spoligotyping of 17 isolates from various organs of the affected animals confirmed an infection by M bovis and revealed an identical pattern indicating a common origin. The spoligotype was different from the pattern of M bovis recorded in the cattle population in Germany between 2000 and 2006. Investigations of sentinel animals such as an aged silver fox (Vulpes vulpes), a badger (Meles meles), a ferret (Mustela putorius) and rodents, and tuberculin skin tests of the animal attendants and randomly collected faecal samples from the enclosures were all negative for M bovis.

    Non-typhoidal salmonellosis is an important zoonotic disease caused by Salmonella enterica. This work focuses on the identification of Salmonella enterica clonal strains which, presenting a wide distribution potential, express resistance determinants that compromise effectiveness of the antimicrobial therapy. The screening was performed on 506 Salmonella enterica isolates from animals and humans, which were characterized by serovar and phage typing, genome macrorestriction and pulsed-field gel electrophoresis, and detection of phenotypic and genotypic traits for antimicrobial resistance. A Salmonella Enteritidis strain with strong quinolone resistance is spread on three host environments carrying one of the four variants found for the GyrA protein: (1) Asp87Tyr, the major polymorphism found in 39 Salmonella isolates from human origin and six from poultry; (2) Ser83Phe, with four isolates from human origin and one from white stork (Ciconia ciconia); and (3) Asp87Asn or (4) Asp87Gly, with two isolates each from human origins. Several Salmonella Typhimurium strains that presented int1 elements and the classically associated pentaresistance (ACSSuT) phenotype were found distributed between two host environments: domestic animals and humans, domestics and wild animals, or wild fauna plus humans. This study points out the importance of monitoring gut microbiota and its antimicrobial resistance from wildlife, in parallel to livestock animals and humans, especially for animal species that are in close contact with people.

    2003-01-01

    Over the past 100 years, the global average temperature has increased by approximately 0.6°C and is projected to continue to rise at a rapid rate. Although species have responded to climatic changes throughout their evolutionary history, a primary concern for wild species and their ecosystems is this rapid rate of change. We gathered information on species and global warming from 143 studies for our meta-analyses. These analyses reveal a consistent temperature-related shift, or `fingerprint', in species ranging from molluscs to mammals and from grasses to trees. Indeed, more than 80% of the species that show changes are shifting in the direction expected on the basis of known physiological constraints of species. Consequently, the balance of evidence from these studies strongly suggests that a significant impact of global warming is already discernible in animal and plant populations. The synergism of rapid temperature rise and other stresses, in particular habitat destruction, could easily disrupt the connectedness among species and lead to a reformulation of species communities, reflecting differential changes in species, and to numerous extirpations and possibly extinctions.

  8. Responses toward a trapped animal by wild bonobos at Wamba.

    2012-07-01

    Chimpanzees and bonobos are the closest living relatives of humans and diverged relatively recently in their phylogenetic history. However, a number of reports have suggested behavioral discrepancies between the two Pan species, such as more cooperative and tolerant social interaction and poorer tool-using repertoires in bonobos. Concerning hunting behavior and meat consumption, recent studies from the field have confirmed both behaviors not only in chimpanzees but also in bonobos. The present study reports an encounter by wild bonobos at Wamba with a duiker trapped in a snare. Bonobos interacted with the live duiker for about 10 min but did not eventually kill the animal. They showed fear responses when the duiker moved and exhibited behaviors related to anxiety and stress such as branch-drag displays and self-scratching. Although bonobos manipulated nearby saplings and parts of the snare, they did not use detached objects to make indirect contact with the duiker. Juveniles and adults of both sexes engaged in active interactions with the trapped duiker. Overall, bonobos' behavioral responses indicated species-specific cognitive characteristics largely different from those of chimpanzees. PMID:22411619

    Most molecular measures of inbreeding do not measure inbreeding at the scale that is most relevant for understanding inbreeding depression-namely the proportion of the genome that is identical-by-descent (IBD). The inbreeding coefficient FPed obtained from pedigrees is a valuable estimator of IBD, but pedigrees are not always available, and cannot capture inbreeding loops that reach back in time further than the pedigree. We here propose a molecular approach to quantify the realized proportion of the genome that is IBD (propIBD), and we apply this method to a wild and a captive population of zebra finches (Taeniopygia guttata). In each of 948 wild and 1057 captive individuals we analyzed available single-nucleotide polymorphism (SNP) data (260 SNPs) spread over four different genomic regions in each population. This allowed us to determine whether any of these four regions was completely homozygous within an individual, which indicates IBD with high confidence. In the highly nomadic wild population, we did not find a single case of IBD, implying that inbreeding must be extremely rare (propIBD=0-0.00094, 95% CI). In the captive population, a five-generation pedigree strongly underestimated the average amount of realized inbreeding (FPed=0.013capture inbreeding loops that reach back up to a few hundred generations.

    Samples (serum or meat juice) collected from 205 animals in New Caledonia in April 2009 were tested for antibodies against Toxoplasma gondii by ELISA using the multi-species ID Screen® Toxoplasmosis Indirect kit (IDVET, Montpellier). Antibodies to T. gondii were detected in 2% (1/49) of the pigs, in 3.3% (1/30) of the cattle, in 13.8% (4/29) of Rusa deers, in 16% (4/25) of the horses, in 32.8% (21/64) of the dogs, and in 50% (4/8) of cats. Statistically, no significant difference was observed between T. gondii seroprevalence and age or sex. No survey on the prevalence of T. gondii in animals has ever been conducted in New Caledonia and this is the first serological evidence of T. gondii in Rusa deer (Cervus timorensis russa).

    1995-03-01

    Diseases and pathogens are receiving increasing recognition as sources of mortality in animal populations. Immune system strength is clearly important in fending off pathogen attack. Physical barriers to pathogen entry are also important. Various individual behaviors are efficacious in reducing contact with diseases and pests. This paper focuses on a fourth mode of defense: social barriers to transmission. Various social behaviors have pathogen transmission consequences. Selective pressures on these social behaviors may therefore exist. Effects on pathogen transmission of mating strategies, social avoidance, group size, group isolation, and other behaviors are explored. It is concluded that many of these behaviors may have been affected by selection pressures to reduce transmission of pathogens. 84 refs., 1 tab.

    The aim of the present study was to evaluate the frequency of antibiotic resistance in Salmonella spp. strains from wild animals in captivity at the Culiacan Zoo and the Mazatlan Aquarium in Sinaloa, Mexico. We identified 17 different Salmonella enterica serovars at a prevalence of 19.90% (Culiacan Zoo) and 6.25% (Mazatlan Aquarium). Antibiotic sensitivity tests revealed that, of the 83 strains studied, 100% were multidrug resistant (MDR). The drugs against which the greatest resistance was observed were: penicillin, erythromycin, dicloxacillin, ampicillin, cephalothin, and chloramphenicol. We therefore conclude that MDR is common among Salmonella isolates originating from wild animals in captivity in Sinaloa. PMID:25282954

    Full Text Available Based on the results of the vertebrate fauna research from 10 Neolithic archaeological sites in Vojvodina (Serbia, two of which belong to Kőrös culture, 7 to Starčevo culture, and one to Vinča culture, the proportional contribution of domestic and wild animals was analysed. These sites were approximately dated between 6000 and 3200 BC. The smallest proportion of domestic animals was recorded at the sites of Golokut-Vizić and Nosa Biserna Obala, while the biggest one at the sites of Prosine-Pećinci, Zlatara-Ruma and Kudoš-Šašinci. A small proportion of domestic animals at Nosa Biserna Obala shows that the animal husbandry was only just at the beginning, and a high proportion of wild animals testifies about the importance of hunting in economy. These are the characteristics of settlements of Kőrös culture, where goats and sheep dominate among domestic animals. Low proportion of domestic and high proportion of wild animals were recorded at the site of Golokut which, like most of the described sites in this paper, belongs to the Middle Neolithic; this is not characteristic for Starčevo culture and it testifies that hunting was much more important than animal husbandry. What is characteristic for settlements of Starčevo culture is the domination of oxen in the total vertebrate fauna and among domestic animals. At the site of Donja Branjevina-Deronje, the settlement which belongs to Starčevo culture as well, goats and sheep have the biggest proportional contribution. The only analysed set­tlement in this paper which belongs to the Early Neolithic (Vinča culture is Gomolava - Hrtkovci where domestic animals dominate, oxen being the most numerous ones.

    A wide array of wildlife species, including many animals, are used in traditional medicines across many medicinal systems, including in Traditional Chinese Medicine (TCM). Due to over-exploitation and habitat loss, the populations of many animals commonly used in TCM have declined and are unable to meet market demand. A number of measures have been taken to try to reduce the impact that this large and growing market for TCM may have on wild animal species. Consumer preferences and behavior are known to play an important role in the consumption and protection of wild animals used in traditional medicine, and thus are likely to be an important factor in the success of many of these mechanisms--particularly given the significant percentage of TCMs that are over-the-counter products (access to which is not mediated by practitioners). In this study we conducted questionnaires and designed stated preference experiments embodying different simulation scenarios using a random sample of the population in Beijing to elicit individuals' knowledge, perceptions and preferences toward wild or farmed animal materials and their substitutes used in traditional Chinese medicine. We found that respondents had a stated preference for wild materials over farm-raised and other alternatives because they believe that the effectiveness of wild-sourced materials is more credible than that of other sources. However, we also found that, although respondents used TCM products, they had a poor understanding of the function or composition of either traditional Chinese medicines or proprietary Chinese medicines (PCM), and paid little attention to the composition of products when making purchasing decisions. Furthermore, awareness of the need for species protection, or "conservation consciousness" was found to play an important role in willingness to accept substitutions for wild animal materials, while traditional animal medicinal materials (TAMs) derived from well-known endangered species, such

    Javier Bustamante

    2013-02-01

    Full Text Available This paper proposes a novel and autonomous weighing system for wild animals. It allows evaluating changes in the body weight of animals in their natural environment without causing stress. The proposed system comprises a smart scale designed to estimate individual body weights and their temporal evolution in a bird colony. The system is based on computational intelligence, and offers valuable large amount of data to evaluate the relationship between long-term changes in the behavior of individuals and global change. The real deployment of this system has been for monitoring a breeding colony of lesser kestrels (Falco naumanni in southern Spain. The results show that it is possible to monitor individual weight changes during the breeding season and to compare the weight evolution in males and females.

    2016-01-01

    Crimean-Congo hemorrhagic fever (CCHF) is a widely distributed, tick-borne viral disease. Humans are the only species known to develop illness after CCHF virus (CCHFV) infection, characterized by a nonspecific febrile illness that can progress to severe, often fatal, hemorrhagic disease. A variety of animals may serve as asymptomatic reservoirs of CCHFV in an endemic cycle of transmission. Seroepidemiological studies have been instrumental in elucidating CCHFV reservoirs and in determining endemic foci of viral transmission. Herein, we review over 50 years of CCHFV seroepidemiological studies in domestic and wild animals. This review highlights the role of livestock in the maintenance and transmission of CCHFV, and provides a detailed summary of seroepidemiological studies of wild animal species, reflecting their relative roles in CCHFV ecology.

    Full Text Available Domestication has led to similar changes in morphology and behavior in several animal species, raising the question whether similarities between different domestication events also exist at the molecular level. We used mRNA sequencing to analyze genome-wide gene expression patterns in brain frontal cortex in three pairs of domesticated and wild species (dogs and wolves, pigs and wild boars, and domesticated and wild rabbits. We compared the expression differences with those between domesticated guinea pigs and a distant wild relative (Cavia aperea as well as between two lines of rats selected for tameness or aggression towards humans. There were few gene expression differences between domesticated and wild dogs, pigs, and rabbits (30-75 genes (less than 1% of expressed genes were differentially expressed, while guinea pigs and C. aperea differed more strongly. Almost no overlap was found between the genes with differential expression in the different domestication events. In addition, joint analyses of all domesticated and wild samples provided only suggestive evidence for the existence of a small group of genes that changed their expression in a similar fashion in different domesticated species. The most extreme of these shared expression changes include up-regulation in domesticates of SOX6 and PROM1, two modulators of brain development. There was almost no overlap between gene expression in domesticated animals and the tame and aggressive rats. However, two of the genes with the strongest expression differences between the rats (DLL3 and DHDH were located in a genomic region associated with tameness and aggression, suggesting a role in influencing tameness. In summary, the majority of brain gene expression changes in domesticated animals are specific to the given domestication event, suggesting that the causative variants of behavioral domestication traits may likewise be different.

  1. Hungry for success: Urban consumer demand for wild animal products in Vietnam

    Directory of Open Access Journals (Sweden)

    Rebecca Drury

    2011-01-01

    Full Text Available Rising urban prosperity is escalating demand for wild animal products in Vietnam. Conservation interventions seek to influence consumer demand, but are based on a limited understanding of consumers and consumption behaviour. This report presents key findings of a structured survey (n=915 and semi-structured interviews (n=78 to investigate the social context of consumption of wild animal-derived products among the population of central Hanoi. Wildmeat is the product most commonly reported consumed-predominantly by successful, high-income, high-status males of all ages and educational levels-and is used as a medium to communicate prestige and obtain social leverage. As Vietnam′s economy grows and its population ages, demand for wildmeat and medicinal products is likely to rise. Given the difficulties of acting on personal rather than collective interests and the symbolic role of wildmeat in an extremely status-conscious society, reducing demand is challenging. Influencing consumer behaviour over the long term requires social marketing expertise and has to be informed by an in-depth understanding, achieved using appropriate methods, of the social drivers of consumer demand for wild animal products. In the meantime, strengthened enforcement is needed to prevent the demand being met from consumers prepared to pay the rising costs of finding the last individuals of a species.

    2003-12-01

    The prevalence of antibodies to Neospora caninum was examined in six wild Artiodactyla species, and in five wild Carnivora species from Kenya. Blood sera (104 wild ungulates from Marula Estates (MEs), and 31 wild carnivores from Masai-Mara reserve and from other wildlife areas in northern and Southern Kenya), were screened using a Neospora agglutination test (NAT), with a twofold dilution (1:40-1:320 titres). Presence of NAT antibodies to N. caninun is reported here for the first time in zebra (Equus burchelli), eland (Taurotragus oryx), African buffalo (Syncerus caffer), Thompson gazelle (Gazella thompsoni), impala (Aepyceros melampus), warthog (Phacochoerus aethiopicus), spotted hyena (Crocuta crocuta) and in free-ranging cheetah (Acinonyx jubatus). At 1:80 dilution, prevalence was 61.5% in eland, 58.5% in zebra, 19.2% in Thompson gazelle, 33.3% in warthog, 50% in African buffalo, 30% in lion (Panthera leo), 20% in cheetah, and 33.3% in spotted hyena. Antibodies up to 1:320 titre were detected in eland (38.4%), zebra (19.5%), Thompson gazelle (3.8%) and lion (5%). Amongst herbivores, sero-prevalence was significantly (P<0.05) higher, at all dilutions, in "grazer/digger" species (e.g. eland and zebra) than in non-"grazer/digger" species (e.g. impala and Thompson gazelle). No antibodies to N. caninum were found in two leopards (Panthera pardus) and one serval (Felis serval). Our results indicates a steady presence of N. caninum in wild mammals from Kenya. The hypothesis of a sylvatic cycle of N. caninum could be suggested, but more data are needed to verify the hypothesis, as to evaluate the role of N. caninum infection on the dynamics of wild animals population in the study area.

    Understanding the exploration patterns of foragers in the wild provides fundamental insight into animal behavior. Recent experimental evidence has demonstrated that path lengths (distances between consecutive turns) taken by foragers are well fitted by a power law distribution. Numerous theoretical contributions have posited that "Lévy random walks"-which can produce power law path length distributions-are optimal for memoryless agents searching a sparse reward landscape. It is unclear, however, whether such a strategy is efficient for cognitively complex agents, from wild animals to humans. Here, we developed a model to explain the emergence of apparent power law path length distributions in animals that can learn about their environments. In our model, the agent's goal during search is to build an internal model of the distribution of rewards in space that takes into account the cost of time to reach distant locations (i.e., temporally discounting rewards). For an agent with such a goal, we find that an optimal model of exploration in fact produces hyperbolic path lengths, which are well approximated by power laws. We then provide support for our model by showing that humans in a laboratory spatial exploration task search space systematically and modify their search patterns under a cost of time. In addition, we find that path length distributions in a large dataset obtained from free-ranging marine vertebrates are well described by our hyperbolic model. Thus, we provide a general theoretical framework for understanding spatial exploration patterns of cognitively complex foragers. PMID:27385831

    Severe fever with thrombocytopenia syndrome (SFTS) is caused by SFTS virus (SFTSV), a novel bunyavirus reported to be endemic to central-northeastern China, southern Japan, and the Republic of Korea (ROK). To investigate SFTSV infections, we collected serum samples and ticks from wild animals. Using serum samples and ticks, SFTSV-specific genes were amplified by one-step RT-PCR and nested PCR and sequenced. Indirect immunofluorescence assay (IFA) was performed to analyze virus-specific antibody levels in wild animals. Serum samples were collected from a total of 91 animals: 21 Korean water deer (KWD), 3 Siberian roe deer, 5 gorals, 7 raccoon dogs, 54 wild boars (WBs), and 1 carrion crow. The SFTSV infection rate in wild animals was 3.30% (3 of 91 animals: 1 KWD and 2 WBs). The seropositive rate was 6.59% (6 of 91 animals: 5 KWD and 1 WB). A total of 891 ticks (3 species) were collected from 65 wild animals (9 species). Of the attached tick species, Haemaphysalis longicornis (74.86%) was the most abundant, followed by Haemaphysalis flava (20.20%) and Ixodes nipponensis (4.94%). The average minimum infection rate (MIR) of SFTSV in ticks was 4.98%. The MIRs of H. longicornis, H. flava, and I. nipponensis were 4.51%, 2.22%, and 22.73%, respectively. The MIRs of larvae, nymphs, and adult ticks were 0.68%, 6.88%, and 5.53%, respectively. In addition, the MIRs of fed and unfed ticks were 4.67% and 4.96%, respectively. We detected a low SFTSV infection rate in wild animals, no differences in SFTSV infection rate with respect to bloodsucking in ticks, and SFTSV infection for all developmental stages of ticks. This is the first report describing the detection of SFTSV in wild animals in the ROK. PMID:27043361

    Full Text Available Clostridium perfringens is a microorganism commonly found in the microbiota of humans and animals and a potential cause of enteric, muscle or nervous diseases. The treatment of these diseases is based on antimicrobial therapy and it is extremely important to know the antimicrobial susceptibility profile of the strains present in the region. The aim of this study was to evaluate the antimicrobial susceptibility of C. perfringens isolated from domestic and wild animals in Brazil against seven different antimicrobials. Forty-one strains from the stool samples of cattle (n = 12, buffalo (n = 2, goat (n = 3, dogs (n = 12 and wild carnivores (n = 12 were examined. The minimum inhibitory concentration was determined by the agar dilution method using Brucella agar supplemented with 5% of sheep blood, 0.1% of vitamin K, 0.1% of hemin and concentrations ranging from 0,25 to 256,0 mg L-1 of the following antibiotics: erythromycin, florfenicol, metronidazole, oxytetracycline, penicillin, tylosin, and vancomycin. All C. perfringens strains were susceptible to florfenicol, metronidazole, penicillin and vancomycin. Two strains (4.9% were resistant to erythromycin and tylosin, while five (12.2% were resistant to oxytetracycline, one of which (2.4% from an ocelot.

  10. Indicators for wild animal offtake: methods and case study for African mammals and birds

    Full Text Available Unsustainable exploitation of wild animals is one of the greatest threats to biodiversity and to millions of people depending on wild meat for food and income. The international conservation and development community has committed to implementing plans for sustainable use of natural resources and has requested development of monitoring systems of bushmeat offtake and trade. Although offtake monitoring systems and indicators for marine species are more developed, information on harvesting terrestrial species is limited. Building on approaches developed to monitor exploitation of fisheries and population trends, we have proposed two novel indicators for harvested terrestrial species: the mean body mass indicator (MBMI assessing whether hunters are relying increasingly on smaller species over time, as a measure of defaunation, by tracking body mass composition of harvested species within samples across various sites and dates; and the offtake pressure indicator (OPI as a measure of harvesting pressure on groups of wild animals within a region by combining multiple time series of the number of harvested individuals across species. We applied these two indicators to recently compiled data for West and Central African mammals and birds. Our exploratory analyses show that the MBMI of harvested mammals decreased but that of birds rose between 1966/1975 and 2010. For both mammals and birds the OPI increased substantially during the observed time period. Given our results, time-series data and information collated from multiple sources are useful to investigate trends in body mass of hunted species and offtake volumes. In the absence of comprehensive monitoring systems, we suggest that the two indicators developed in our study are adequate proxies of wildlife offtake, which together with additional data can inform conservation policies and actions at regional and global scales.

    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

    Full Text Available Domestic dogs' skills such as hunting and herding shifted as man migrated from rural areas to developing urban centers and led to a change in human-dog relationship and in the purpose of these animals in the properties. The countryside of Viçosa is characterized by small coffee farms surrounded by borders with fragments from the Brazilian Atlantic Forest. The close proximity of these environments favors the encounter between domestic and wild animals which may lead to dog attacks to wild animals and, consequently, disease transmission. The aim of this study was to understand the role of dogs in the rural environment and assess the possible risks they offer to native fauna. The data were obtained from structured questionnaires answered by dogs' owners from rural Viçosa. Results regarding the socioeconomic status of the owners revealed that the majority belonged to either the middle class or low educational level categories. In addition, it was observed that there is a preference for male dogs due to its guard activity and that most dogs live unconstrained. Even though most dogs are provided with good food management, 58% of them prey on wildlife. However, more than half of the dogs do not consume their prey which can be explained by the inherited ability of artificial selection but 36.5% of them have scavenger diet. Most of the dogs were immunized against rabies, whereas, only 28.8% were immunized against infectious diseases such as leptospirosis, distemper and parvovirus. In conclusion, the management of dogs by rural owners, mainly unrestrained living, and allied to inadequate vaccination coverage suggest that dogs are predators of Viçosa's rural wildlife and potential disseminators of disease.

    Wild animals contribute to endemic infection in livestock as well as the introduction, reintroduction and maintenance of pathogens. The source of introduction of endemic diseases to a piggery is often unknown and the extent of wildlife contribution to such local spread is largely unexplored. The aim of the current study was to quantitatively assess the probability of domestic pigs being exposed to different pathogens from wild animals commonly found around commercial piggeries in Australia. Specifically, this study aims to quantify the probability of exposure to the pathogens Escherichia coli, Salmonella spp. and Campylobacter spp. from European starlings (Sturnus vulgarus); Brachyspira hyodysenteriae, Lawsonia intracellularis and Salmonella spp. from rats (Rattus rattus and Rattus norvegicus); and Mycoplasma hyopneumoniae, Leptospira spp., Brucella suis and L. intracellularis from feral pigs (Sus scrofa). Exposure assessments, using scenario trees and Monte Carlo stochastic simulation modelling, were conducted to identify potential pathways of introduction and calculate the probabilities of these pathways occurring. Input parameters were estimated from a national postal survey of commercial pork producers and from disease detection studies conducted for European starlings, rats and feral pigs in close proximity to commercial piggeries in Australia. Based on the results of the exposure assessments, rats presented the highest probability of exposure of pathogens to domestic pigs at any point in time, and L. intracellularis (median 0.13, 5% and 95%, 0.05-0.23) and B. hyodysenteriae (median 0.10, 0.05-0.19) were the most likely pathogens to be transmitted. Regarding European starlings, the median probability of exposure of domestic pigs to pathogenic E. coli at any point in time was estimated to be 0.03 (0.02-0.04). The highest probability of domestic pig exposure to feral pig pathogens at any point in time was found to be for M. hyopneumoniae (median 0.013, 0

    Since 1986, scrapie-like spongiform encephalopathy has been diagnosed in 19 captive wild animals of eight species at or from eight zoological collections in the British Isles. The affected animals have comprised members of the family Bovidae: one nyala (Tragelaphus angasi), four eland (Taurotragus oryx), and six greater kudu (Tragelaphus strepsiceros), one gemsbok (Oryx gazella), one Arabian oryx (Oryx leucoryx), and one scimitar-horned oryx (Oryx dammah), and members of the family Felidae: four cheetah (Acinonyx jubatus) and one puma (Felis concolor). In addition, three cases of a spongiform encephalopathy of unknown aetiology have been reported in ostriches (Struthio camellus) from two zoos in north west Germany. Three features suggest that some of these cases may have been caused by the agent of bovine spongiform encephalopathy (BSE). First, they have been temporally and geographically coincident with the BSE epidemic. Secondly, in all the ungulates for which details are available, it is possible that either the affected animal itself, or the herd into which it was born or moved, had been exposed to proprietary feeds containing ruminant-derived protein or other potentially contaminated material, and all the carnivores had been fed parts of cattle carcases judged unfit for human consumption. Thirdly, the pathological results of inoculating mice with a homogenate of fixed brain tissue from the nyala and from one greater kudu were similar to the results of inoculating mice with BSE brain tissue.

    Full Text Available Listeria species were isolated from faecal samples collected from different captive wild animals of Nandankanan Zoo, Baranga, Odisha, using selective enrichment medium. The isolates were characterized based on their cell morphology, biochemical and sugar fermentation characteristics as well as culture morphology. Further, in vitro and in vivo pathogenicity tests were carried out to assess the pathogenic potential of the isolates. Listeria were found in 24 (23.07% of the total 104 faecal samples. Listeria were isolated from the samples of tiger, bear, hyena, leopard, zebra, elephant, jackal, lion, barking deer, porcupine, chital, monkey and wild boar. Out of the 24 Listeria isolates 11 were confirmed as L. monocytogenes. The other 13 isolates included L. innocua, L. seeligeri, L. welshimeri and L. ivanovii. The pathogenicity study revealed that only four isolates were pathogenic. Three of these were L. monocytogenes isolated from tiger, hyena and elephant and one was L. ivanovii isolated from leopard. Antibiotic sensitivity of the 24 isolates was high towards ciprofloxacin, levofloxacin, amoxicillin, azithromycin and enrofloxacin. The isolates showed resistance towards oxytetracyclin, gentamicin, cephadroxil, penicillin- G and nalidixic acid.

    Toxoplasmosis stands out as a global disease that has felines as definitive hosts. In the municipality of Natal, Rio Grande do Norte State, Brazil, two parks are notable for their ecological and social importance. This study aimed to investigate the presence of Toxoplasma gondii in short hair cats, bats and small non-volant mammals in these two ecological reserves. Altogether, biological samples were obtained from 154 mammals, 92 wild animals from both areas and 62 domestic cats of the Parque da Cidade. In total, 22 (53.7%) non-volant wild mammals, 11 (21.5%) bats and 28 (52.8%) cats were positive for IgG anti-T. gondii antibodies using the Modified Agglutination Test (≥ 25). It was possible to detect the presence of T. gondii DNA, by means of a molecular amplification of a B1 gene fragment (155bp), in 92 tissue samples from wild animals, including Didelphis albiventris, Monodelphis domestica, Artibeus lituratus, Carollia perspicillata and Glossophaga soricina. Of the 62 cats examined by the same molecular method, T. gondii DNA could be detected in 4 cats. In this study, it was observed the circulation of T. gondii in wild species and domestic cats, demonstrating the involvement of wild and domestic animals in the cycle of T. gondii. PMID:25517529

    Fecal samples obtained from wild boar habitats are useful for the surveillance of diseases in wild boar populations; however, it is difficult to determine the species of origin of feces collected in natural habitats. In this study, a fecal IgA ELISA was evaluated as a method for identifying the porcine species from fecal samples. Both domestic pigs (Sus scrofa domestica) and wild boars (Sus scrofa coreanus) showed significantly higher levels of fecal IgA than other animal species. Additionally, age dependent changes in the level of Ig A in wild boars and domestic pigs were identified; Titers of Ig A were highest in suckling period and lowest in weanling period. PMID:27340389

    Ticks collected in the last two decades from free-living and captive wild animals from 28 municipalities of the Brazilian state of Mato Grosso were identified and tested using molecular methods for the presence of rickettsial agents. A total of 4467 ticks (229 larvae, 1676 nymphs, 1565 males, 997 females) representing 27 ixodid species were collected from 235 species of amphibians, reptiles, birds, and mammals from three different ecoregions (Pantanal, Cerrado, and Amazonia). The species Amblyomma parkeri, Amblyomma romitii, Amblyomma varium and Ixodes luciae are reported for the first time in the state of Mato Grosso. Amongst 538 ticks tested by molecular methods for rickettsial infection, we detected 'Candidatus Rickettsia amblyommii' infecting Amblyomma cajennense sensu stricto and Amblyomma coelebs, Rickettsia sp. strain Atlantic rainforest infecting Amblyomma ovale, Rickettsia sp. strain NOD infecting Amblyomma nodosum, and 'Candidatus Rickettsia andeanae' infecting Amblyomma sculptum. Our results represent an impressive expansion of knowledge on tick fauna and rickettsiae and are essential for understanding the ecology of ticks and tick-borne diseases in the Neotropical region, particularly in midwestern Brazil.

    From 2005 to 2009, 147 ticks found on 32 wild animals from or referred to two zoobotanical parks (Parque Zoobotânico Arruda Câmara and Parque Estadual Dois Irmãos) located in northeastern Brazil were identified. Ticks found on two veterinarians working in one of the parks (i.e., Parque Estadual Dois Irmãos), after return from forested areas within the park's territory, were also identified. The following tick-host associations were recorded: Amblyomma fuscum Neumann on Boa constrictor L.; Amblyomma longirostre Koch on Ramphastos vitellinus ariel Vigors and Coendou prehensilis (L.); Amblyomma varium Koch on Bradypus variegates Schinz; Amblyomma rotundatum Koch on Chelonoidis carbonaria (Spix), Chelonoidis denticulata (L.), Micrurus ibiboboca (Merrem), Python molurus bivittatus Kuhl, Iguana iguana (L.) and B. variegatus; Amblyomma nodosum Neumann on Myrmecophaga tridactyla L. and Tamandua tetradactyla (L.); and Rhipicephalus sanguineus (Latreille) on Nasua nasua (L.). The ticks found on the veterinarians were identified as nine Amblyomma larvae. The presence of Am. nodosum in Pernambuco and Am. rotundatum and Am. varium in Paraíba is recorded for the first time and the occurrence of Am. longirostre in Pernambuco is confirmed. Ramphastos vitellinus ariel is a new host record for Am. longirostre whereas M. ibiboboca and B. variegatus are new host records for Am. rotundatum. Finally, the human parasitism by Amblyomma ticks is reported for the first time in Pernambuco, highlighting the potential of tick-borne pathogen transmission in this state. PMID:19693679

  7. Soil- to-Whole Body Transfer Factors of Radionuclides for Terrestrial Wild Animals Living around the Gyeongju Nuclear Site

    International Nuclear Information System (INIS)

    In the Gyeongju nuclear site, a low and medium level radioactive waste repository and five nuclear reactors are currently operating. The IAEA and ICRP consider it necessary to demonstrate that not only men but also wild organisms are protected from ionizing radiations. Therefore, it may not be long before the dose assessment for wildlife should be carried out in Korea. The transfer factor (TF) defined as the concentration ratio between an organism and an environmental medium is a key parameter in assessing the radiation dose to wildlife. For eight animal species inhabiting mountainous areas around the Gyeongju nuclear site, the TF values of 22 stable elements were measured. The acquired values varied considerably with the elements and animal species. Further TF data need to be produced for various Korean wild animal and plant species in preparation for future governmental regulations of wildlife exposure to ionizing radiations

Some species have become extinct due to naturalcauses but the greatest danger to wild life result from human activities. Thuswe ourselves have created this need for wild life conservation. The progress ofman throughout has been beneficial for the human race but it is the wild thathas suffered through the years. Invention of sophisticated weapons,industrialization, urbanization, ever increasing human population have beensome of the major causes for the dwindle of our once rich wild life resource.Hunting, clearing of forests, draining of swamps and damming of rivers forirrigation and industry, this is what we apprise of man’s progress.

    Tularemia, a highly infectious zoonotic disease caused by Francisella tularensis, occurs sporadically in Japan. However, little is known about the prevalence of the disease in wild animals. A total of 632 samples obtained from 150 Japanese black bears, 142 Japanese hares, 120 small rodents, 97 rats, 53 raptors, 26 Japanese monkeys, 21 Japanese raccoon dogs, 20 masked palm civets, and three Japanese red foxes between 2002 and 2010 were investigated for the presence of antibodies to F. tularensis by competitive enzyme-linked immunosorbent assay (cELISA) and the commonly used microagglutination (MA) test. Seropositive cELISA and MA results were obtained in 23 and 18 Japanese black bears, three and two Japanese raccoon dogs, and two and one small rodents, respectively. All MA-positive samples (n=21) were also positive by cELISA. Six of seven samples that were only positive by cELISA were confirmed to be antibody-positive by western blot analysis. These findings suggest that cELISA is a highly sensitive and useful test for serosurveillance of tularemia among various species of wild animals. Because this is the first study to detect F. tularensis-seropositive Japanese raccoon dogs, these could join Japanese black bears as sentinel animals for tularemia in the wild in Japan. Further continuous serosurveillance for F. tularensis in various species of wild animals using appropriate methods such as cELISA is important to assess the risks of human exposure and to improve our understanding of the ecology of F. tularensis in the wild.

    Despite thousands of papers on the topic, precious few of the studies on animal personality have considered the role of personality in shaping community-level processes. Here, we test the effect of individual variation on the long-term trajectories of biological communities, from initiation to their demise. The spider Anelosimus studiosus builds webs that serve as habitat for >50 species of spider, which together construct a species-rich silken reef. This species also exhibits a temporally consistent behavioural polymorphism where females exhibit either an aggressive or docile phenotype (personality). In this study, we established incipient colonies of either two docile or two aggressive females and then tracked community succession and persistence over 7 years in the field. In particular, we noted the community compositions associated with colony extinction/collapse events, which are common in this species. The community composition of webs founded by different phenotypes diverged rapidly in their early successional stages. However, this period of divergence was ephemeral and all communities eventually converged on a similar composition; communities founded by aggressive females merely took longer to reach it. This secondary stage of community convergence was itself short-lived and independent of founders' personality; all communities collapsed within a year of achieving it. Experimentally imposing this fatal climax composition on colonies caused 80% of communities to collapse within a year, suggesting that this climax composition actually causes the collapse of the community. Community collapse was characterized by a complete die-off of the foundation species and the dispersal of all other spiders. Thus, the behavioural traits of the founding, foundational individuals of these communities dictate their path of succession and longevity in the wild. PMID:26061961

    Full Text Available Fleas were collected from 61 wild carnivores belonging to 13 species in various nature reserves and on farms, two feral domestic cats in a nature reserve and a domestic dog in the city of Johannesburg. Eleven flea species, including two subspecies of one of these, belonging to six genera were recovered. Amongst these only Ctenocephalides felis felis and Ctenocephalides felis strongylus are considered specific parasites of carnivores. The remaining ten species normally infest the prey animals of the various carnivores.

    2011-05-01

    We report an investigation of antibodies to Toxoplasma gondii in 52 wild birds and 20 wild mammals from northern and central areas of Portugal by using the modified agglutination test. The birds comprised 26 common buzzards (Buteo buteo), five tawny owls (Strix aluco), four white storks (Ceconia ceconia), three Eurasian eagle owls (Bubo bubo), three northern goshawks (Accipiter gentilis), two booted eagles (Hieraaetus pennatus), two common barn owls (Tyto alba), two Eurasian sparrowhawks (Accipiter nisus), two short-toed eagles (Circaetus gallicus), one black kite (Milvus migrans), one Griffin vulture (Gyps fulvus), and one peregrine falcon (Falco peregrinus). The mammals were eight wild boars (Sus scrofa), six red foxes (Vulpes vulpes), two common genets (Genetta genetta), two European badgers (Meles meles), one European roe deer (Capreolus capreolus), and one Iberian wolf (Canis lupus signatus). Fifty percent of the wild birds and 90% of the wild mammals were seropositive; the overall seroprevalence of infection was 61.1%. When comparing the prevalence of antibodies in birds and mammals from northern Portugal, a significant difference was found, but the same was not true for birds and mammals from central Portugal. Seroprevalence levels were 30.0% in juvenile and 62.5% in adult birds (p=0.046), 0.0% in juvenile and 94.7% in adult mammals (p=0.100), 80.0% in female and 66.7% in male birds (p=1.000), and 81.8% in female and 100% in male mammals (p=0.479). This is the first study performed on T. gondii in birds of prey, white storks, and wild carnivores in Portugal. PMID:21104273

  16. Diagnosis of tuberculosis in the wild boar (Sus scrofa: a comparison of methods applicable to hunter-harvested animals.

    Directory of Open Access Journals (Sweden)

    Nuno Santos

    Full Text Available BACKGROUND: To obtain robust epidemiological information regarding tuberculosis (TB in wildlife species, appropriate diagnostic methods need to be used. Wild boar (Sus scrofa recently emerged as a major maintenance host for TB in some European countries. Nevertheless, no data is available to evaluate TB post-mortem diagnostic methods in hunter-harvested wild boar. METHODOLOGY/PRINCIPAL FINDINGS: Six different diagnostic methods for TB were evaluated in parallel in 167 hunter-harvested wild boar. Compared to bacteriological culture, estimates of sensitivity of histopathology was 77.8%, gross pathology 72.2%, PCR for the MPB70 gene 66.7%, detection of acid-fast bacilli (AFB in tissue contact smears 55.6% and in histopathology slides 16.7% (estimated specificity was 96.7%, 100%, 100%, 94.4% and 100%, respectively. Combining gross pathology with stained smears in parallel increased estimated sensitivity to 94.4% (94.4% specificity. Four probable bacteriological culture false-negative animals were identified by Discriminant Function Analysis. Recalculating the parameters considering these animals as infected generated estimated values for sensitivity of bacteriology and histopathology of 81.8%, gross pathology 72.7%, PCR for the MPB70 gene 63.6%, detection of AFB in tissue contact smears 54.5% and in histopathology slides 13.6% (estimated specificity was 100% for gross pathology, PCR, bacteriology and detection of AFB in histopathology slides, 96.7% for histopathology and 94.4% for stained smears. CONCLUSIONS/SIGNIFICANCE: These results show that surveys for TB in wild boar based exclusively on gross pathology considerably underestimate prevalence, while combination of tests in parallel much improves sensitivity and negative predictive values. This finding should thus be considered when planning future surveys and game meat inspection schemes. Although bacteriological culture is the reference test for TB diagnosis, it can generate false

    Among a variety of uncommon firearms of different origin used worldwide, the trap gun used in Sri Lanka is underreported. This is an illegal, locally made, smooth-bore, long-barreled, muzzle-loading firearm with a victim-activated simple trigger mechanism. It is mainly used to protect crops and livestock from the potential harm by wild animals. Trap gun is mounted horizontally on pegs of sticks fixed to the ground. Miscellaneous metal pieces are used as ammunition. A small metal container filled with powdered matchstick heads/firecrackers covered by the striker surface of the matchstick box is used as the percussion cap. A metal hammer is set to hit the percussion cap. Through a lever mechanism, the hammer is kept under tension. The lever mechanism is connected to a trigger cord, which runs across the animal path. The first passerby, a human being or a wild animal, who accidentally trips the trigger cord and activates the trigger mechanism is critically injured. This characteristically damages the lower limbs of the human being. This communication highlights a death due to trap gun injury. The injury pattern caused by trap gun could overlap with that of shotgun and rifled firearm. A meticulous autopsy could sort it out. PMID:24457573

    Authors report results emerging from gastric content analysis from n. 96 wild boars hunted in Sardinia isle, during the hunting tide (2001-2005), from November to January. Mean pH of the gastric content was 3.77 +/- 0.69. Mean total capacity (TC) of each stomach was 1702 +/- 680 g. Mean Stuff ratio (CW/TC) between the content weight (CW) and stomachs TC was 0.45. Food categories found in animal stomachs were: 19 categories of vegetal species (Allium spp., Arbutus unedo, Arisarum vulgare, Avena fatua, Avena sativa, Castanea sativa, Ceratonia siliqua, Chamaerops umilis, Cichorium intybus, Hordeum sativum, Juniperus oxycedrus, Myrtus communis, Olea europea, Pirus amygdaliformis, Pistacia lentiscus, Quercus spp., Rhamnus alaternus, Triticum durum, Zea mais); 11 categories of animal species (Agriotes lineatus, Apodemus sylvaticus dicrurus, Chalcides chalcides, Chalcides ocellatus tiligugu, Crematogaster scutellaris, Forficula auricularia, Helix aspersa, Lumbricus terrestris, Ovis aries, Podarcis tiliguerta tiliguerta, Scolopendra cingulata); three categories were identified in general terms (insects larvae, hairs of mammals, feathers of birds). Food categories found in the stomach contents of Sus scrofa meridionalis confirm observations by other researchers who report the prevalence of vegetables in spite of animal food sorts in the wild boar diet in Italian regions.

    Full Text Available A serosurvey was conducted in wild animals captured close to two areas where hantavirus cardiopulmonary syndrome (HCPS occurred in São Paulo State, Brazil. Serum samples from a total of 43 mammals were tested for antibodies reactive with Sin Nombre (SN hantavirus using a strip immunoblot assay. RNAs from the blood clots of the positive samples were submitted to reverse transcriptase-polymerase chain reaction (RT-PCR. Two rodents of the genus Oligoryzomys were positive for hantavirus antibodies. These animals were captured in the Iguape region and represented 16.7% (2/12 of the sera from rodents and 100.0% (2/2 of the Oligoryzomys captured in that area. RT-PCR failed to amplify any viral cDNA. These results are in agreement with other data that suggest that members of this genus are important reservoirs of hantaviruses in Brazil.

    Sixty Giardia duodenalis isolates from domestic (n=49) and wild (n=11) animals (dogs, cats, deers, wolves, raccoon dog and muskrat) were analysed by PCR-RFLP at glutamate dehydrogenase locus (gdh). The isolates were obtained from positive feces samples for Giardia cysts analysed by flotation technique with saturated sodium chloride solution (specific gravity 1.28). Three G. duodenalis genotypes were identified: C (10/60; 16.7%); D (42/60; 70.0%); and E (7/60; 11.7%). In dogs all three genotypes were found, with the following prevalences: 76.9% genotype D (30/39); 23.1% C (9/39); 2.6% genotype E (1/39). One dog was co-infected with C and D genotypes. In cats we identified only G. duodenalis genotype D. Wolves and raccoon dog harbored infection with G. duodenalis genotype D, deers with E type and muskrat C type. This is the first study regarding genotyping of G. duodenalis in cats and wild animals from Romania. To the best of our knowledge, this is the first report of assemblages E in roe deers; assemblage C in wolves and muskrat; and assemblage D in raccoon dog. PMID:26827864

    Full Text Available Aim: The study was conducted to know the prevalence of gastrointestinal parasites of captive wild animals at Bir Moti Bagh Mini Zoo (Deer Park, Patiala, Punjab. Materials and Methods: A total of 31 fecal samples from eight species of captive animals including Civet cat (Viverra zibetha, Porcupine (Hystrix indica, Nilgai (Boselaphus tragocamelus, Spotted deer (Axis axis, Black buck (Antelope cervicapra, Sambar deer (Cervus unicolor, Hog deer (Axis porcinus, and Barking deer (Muntiacus muntjak were screened using classical parasitological techniques including sedimentation and floatation technique. Results: Out of 31 fecal samples examined, 20 were positive for parasitic ova/oocysts of different species indicating an overall prevalence of 68.0%. The six different types of parasites observed in the study included strongyle (67%, Strongyloides spp. (14%, coccidia (38%, Trichuris spp. (19%, ascarid (10%, and Capillaria spp. (10%. Strongyles were the most common parasites observed (67% followed by coccidia (38%. Mixed helminth and protozoan infection were observed in 48% of animals. No cestode or trematodes were detected during the study. Conclusion: The high prevalence of gastrointestinal parasites without overt clinical signs of disease or mortality as observed in this study is suggestive of subclinical infection. The findings will help in formulating the appropriate deworming protocol for parasitic control in these captive animals.

    We report molecular evidence for the presence of spotted fever group rickettsiae (SFGR) in ticks collected from roe deer, addax, red foxes, and wild boars in Israel. Rickettsia aeschlimannii was detected in Hyalomma marginatum and Hyalomma detritum while Rickettsia massiliae was present in Rhipicephalus turanicus ticks. Furthermore, a novel uncultured SFGR was detected in Haemaphysalis adleri and Haemaphysalis parva ticks from golden jackals. The pathogenicity of the novel SFGR for humans is unknown; however, the presence of multiple SFGR agents should be considered when serological surveillance data from Israel are interpreted because of significant antigenic cross-reactivity among Rickettsia. The epidemiology and ecology of SFGR in Israel appear to be more complicated than was previously believed. PMID:22049050

    Species of the genus Spirometra are diphyllobothriid tapeworms with complex life cycles and are involved in human sparganosis, a neglected disease that affects individuals worldwide. Although some species were reported in wild felids and human cases of sparganosis were described in Brazil, the biology and taxonomy of these parasites are poorly understood. In the present study, samples of diphyllobothriids (eggs and/or proglottids) obtained from the stools of wild carnivores (Leopardus pardalis and Lycalopex vetulus) and plerocercoid larvae found in a snake (Crotalus durissus) from Brazil were analysed by amplifying a fragment of the gene cytochrome c oxidase subunit 1 (cox 1). The DNA sequences obtained here for the first time from the Spirometra spp. from Brazil were used to evaluate the phylogenetic relationships with other species. Molecular data identified two species in the Brazilian samples (evolutionary divergence of 17.8-19.2%). The species were identified as Spirometra sp. 1, found in Le. pardalis, and Spirometra sp. 2 found in Ly. vetulus and C. durissus, and they differed from Asian isolates of Spirometra erinaceieuropaei (17.5-20.2% and 12.2-15.6%, respectively), a species previously considered to be distributed worldwide. Moreover, Spirometra sp. 1 is genetically distinct from Sparganum proliferum from Venezuela (19.6-20.4%), while Spirometra sp. 2 is more closely related with the Venezuelan species (6.1-7.0%). Sequences of Spirometra sp. 2 revealed that it is conspecific with the Argentinean isolate of Spirometra found in Lycalopex gymnocercus (1.9-2.2%). Taxonomic and phylogenetic aspects related to New World species of Spirometra are briefly discussed. PMID:27235572

    Full Text Available Wild animals are infected by diverse parasites, but how they influence host health is poorly understood. We examined the relationship of trypanosomatids and gastrointestinal parasites with health of wild brown-nosed coatis (Nasua nasua from the Brazilian Pantanal. We used coati body condition and hematological parameters as response variables in linear models that were compared using an information theoretic approach. Predictors were high/low parasitemias by Trypanosoma cruzi and T. evansi, and indices representing the abundance of distinct groups of gastrointestinal parasites. We also analyzed how host health changed with host sex and reproductive seasonality. Hemoparasites was best related to coati body condition and hematological indices, whereas abundance of gastrointestinal parasites was relatively less associated with coati health. Additionally, some associations were best predicted by models that incorporated reproductive seasonality and host sex. Overall, we observed a lower health condition during the breeding season, when coatis are under reproductive stress and may be less able to handle infection. In addition, females seem to handle infection better than males. Body condition was lower in coatis with high parasitemias of T. evansi, especially during the reproductive season. Total red blood cell counts, packed cell volume, platelets and eosinophils were also lower in animals with high T. evansi parasitemias. Total white blood cell counts and mature neutrophils were lower in animals with high parasitemias for both Trypanosoma species, with neutrophils decreasing mainly during the reproductive season. Overall, decreases in hematological parameters of females with T. evansi high parasitemias were less evident. For T. cruzi, monocytes decreased in individuals with high parasitemias. High abundances of microfilariae in the bloodstream, and cestode eggs and coccidian oocysts in feces were also associated with coati blood parameters. This

Total white blood cell counts and mature neutrophils were lower in animals with high parasitemias for both Trypanosoma species, with neutrophils decreasing mainly during the reproductive season. Overall, decreases in hematological parameters of females with T. evansi high parasitemias were less evident. For T. cruzi, monocytes decreased in individuals with high parasitemias. High abundances of microfilariae in the bloodstream, and cestode eggs and coccidian oocysts in feces were also associated with coati blood parameters. This study shows the

    Studying animal movement and distribution is of critical importance to addressing environmental challenges including invasive species, infectious diseases, climate and land-use change. Motion sensitive camera traps offer a visual sensor to record the presence of a broad range of species providing location -specific information on movement and behavior. Modern digital camera traps that record video present new analytical opportunities, but also new data management challenges. This paper describes our experience with a terrestrial animal monitoring system at Barro Colorado Island, Panama. Our camera network captured the spatio-temporal dynamics of terrestrial bird and mammal activity at the site - data relevant to immediate science questions, and long-term conservation issues. We believe that the experience gained and lessons learned during our year long deployment and testing of the camera traps as well as the developed solutions are applicable to broader sensor network applications and are valuable for the ad...

    Artificial selection is the selection of advantageous natural variation for human ends and is the mechanism by which most domestic species evolved. Most domesticates have their origin in one of a few historic centers of domestication as farm animals. Two notable exceptions are cats and dogs. Wolf domestication was initiated late in the Mesolithic when humans were nomadic hunter-gatherers. Those wolves less afraid of humans scavenged nomadic hunting camps and over time developed utility, initi...

    Objective: To determine the prevalence of zoonotic tick-borne bacteria in feeding ticks removed from hunted wild animals. Methods: PCR was executed on DNA extracted from 77 tick pools to detect Anaplasma phagocytophilum, Bartonella spp., Borrelia burgdorferi sensu lato, Coxiella burnetii and Rickettsia spp. Results: A total of 432 ticks were collected: 30(6.94%) Haemaphysalis punctata, 72(16.7%) Dermacentor marginatus and 330(76.38%) Ixodes ricinus. For each animal one or two pools of 3 ticks of the same species was constituted. Seventy-seven tick pools were examined by PCR: 58(75.32%) resulted infected and among them 14(18.18%) showed co-infections. In particular, 29(37.66%) pools were positive for Bartonella spp., 23(29.87%) for Anaplasma phagocytophilum, 16(20.78%) for Rickettsia spp., and 5(6.49%) for Borrelia burgdorferi s.l. All samples were negative for Coxiella burnetii. Conclusions: The results demonstrate the presence of several zoonotic tick-borne pathogens in the studied area, and underline the risk of exposure to infections for hunters not only during the outdoor activity, but also when they manipulate hunted animals infested by infected ticks.

  12. A systematic review of the epidemiology of echinococcosis in domestic and wild animals.

    Directory of Open Access Journals (Sweden)

    Belen Otero-Abad

    Full Text Available BACKGROUND: Human echinococcosis is a neglected zoonosis caused by parasites of the genus Echinococcus. The most frequent clinical forms of echinococcosis, cystic echinococcosis (CE and alveolar echinococcosis (AE, are responsible for a substantial health and economic burden, particularly to low-income societies. Quantitative epidemiology can provide important information to improve the understanding of parasite transmission and hence is an important part of efforts to control this disease. The purpose of this review is to give an insight on factors associated with echinococcosis in animal hosts by summarising significant results reported from epidemiological studies identified through a systematic search. METHODOLOGY AND PRINCIPAL FINDINGS: The systematic search was conducted mainly in electronic databases but a few additional records were obtained from other sources. Retrieved entries were examined in order to identify available peer-reviewed epidemiological studies that found significant risk factors for infection using associative statistical methods. One hundred studies met the eligibility criteria and were suitable for data extraction. Epidemiological factors associated with increased risk of E. granulosus infection in dogs included feeding with raw viscera, possibility of scavenging dead animals, lack of anthelmintic treatment and owners' poor health education and indicators of poverty. Key factors associated with E. granulosus infection in intermediate hosts were related to the hosts' age and the intensity of environmental contamination with parasite eggs. E. multilocularis transmission dynamics in animal hosts depended on the interaction of several ecological factors, such as hosts' population densities, host-prey interactions, landscape characteristics, climate conditions and human-related activities. CONCLUSIONS/SIGNIFICANCE: Results derived from epidemiological studies provide a better understanding of the behavioural, biological and

    Disease and pathogens have been studied as regulators of animal populations but not really as selective forces. The authors propose that pathogens can be major selective forces influencing social behaviors when these are successful at reducing disease transmission. The behaviors whose evolution could have been influenced by pathogen effects include group size, group isolation, mixed species flocking, migration, seasonal sociality, social avoidance, and dominance behaviors. Mate choice, mating system, and sexual selection are put in a new light when examined in terms of disease transmission. It is concluded that pathogen avoidance is a more powerful selective force than has heretofore been recognized.

    Plague surveillance is routinely conducted to predict future epizootics in wildlife and exposure risk for humans. The most common surveillance method for sylvatic plague is detection of antibodies to Yersinia pestis F1 capsular antigen in sentinel animals, such as coyotes (Canis latrans). Current serologic tests for Y. pestis, hemagglutination (HA) test and enzyme-linked immunosorbent assay (ELISA), are expensive and labor intensive. To address this need, we developed a complete lateral flow device for the detection of specific antibodies to Y. pestis F1 and V antigens. Our test detected anti-F1 and anti-V antibodies in serum and Nobuto filter paper samples from coyotes, and in serum samples from prairie dogs (Cynomys ludovicianus), lynx (Lynx canadensis), and black-footed ferrets (Mustela nigripes). Comparison of cassette results for anti-F1 and anti-V antibodies with results of ELISA or HA tests showed correlations ranging from 0.68 to 0.98. This device provides an affordable, user-friendly tool that may be useful in plague surveillance programs and as a research tool.

    In human tuberculosis (Mycobacterium tuberculosis), molecular epidemiology has accurately indicated the risk factors involved in active transmission of the disease, by comparing individuals whose isolates belong to a cluster with patients whose strains are considered unique. Nevertheless, this application has not been used in bovine tuberculosis (Mycobacterium bovis). Our study describes the integration of epidemiological data into molecular classification data on M. bovis isolates. These were isolated from wild ungulates in Extremadura (western Spain) with the objective of detecting the risk factors linked to the association of strains in clades, which are indicators of the active spread of the disease. The molecular markers used were spoligotyping + VNTR typing (loci: VNTR 2165, VNTR 2461, VNTR 0577, VNTR 0580, VNTR 3192 VNTR 2163a and VNTR 2163b) on a population of 59 M. bovis strains isolated from deer (Cervus elaphus), 112 from wild boar (Sus scrofa), six from bovines, 28 from pigs and 2 from goats (n=207). Epidemiological variables included the animal species from which the strain was isolated, pathological condition of the host (incipient lesion, early and late generalisation), date of sampling (during or after the reproductive period) and hunting season. Bivariant analysis was used to establish the risk factors connected to the association of strains and later, the variables were evaluated by means of logistic regression. Molecular typing grouped a total of 131 strains (64.21%) in 28 clusters and 76 isolates shows unique profiles. The association of strains was connected to the appearance of macroscopic lesions during the reproductive period (O.R. 4.80; 95% CI 1.09-22.99, PActive spread was not connected to any species in particular, or to any concrete pathological condition.

    Full Text Available In order to review evidence of human-animal relations, the paper offers an overview of the customs and funerary traditions of the Square Mouthed Pottery culture, between c. 5000 and 4300 calBC. We focus on the importance of domestic and wild animals on the basis of an analysis of grave-goods, funerary rites and personal ornaments. We also consider recent discoveries of peculiar offerings of animals and some dog burials. The evidence testifies to a diffusion of a wild component, symbolically emphasising the importance of the hunter identity in a society where subsistence actually depends primarily on domestic animals. Therefore, a contrast is drawn between the everyday and the symbolic worlds.

    Full Text Available Digestive and respiratory tracts parasite’s protozoan, Cryptosporidium spp. now-a-days is a major zoonotic agent, it causes self-limiting diarrhea, remaining in the body passively until the moment immune system decreases, leading to an increase in its multiplication in the mucosa and appearance of clinical signs. As there are few studies on cryptosporidiosis in wild free-living and captive animals, especially in Brazil, this study aimed to identify the presence of Cryptosporidium spp. in feces of captive animals in Cascavel, PR Municipal Zoo. Between 2011 and 2012 there have been four collections of bird feces and five mammalian feces totaling 65 and 118 samples respectively. Samples were sent to the laboratory of Veterinary Parasitology of Federal University of Parana. The feces were diluted, centrifuged and the pellets were used to make blades which were stained by the Ziehl-Neelsen modified method and observed under a microscope with 1000X magnification. Then the blades containing the oocysts were observed under a capture microscope, where they were measured. Mammals showed 49.15% and birds 44.61% of positivity. Oocysts’ sizes ranged from 3,54?m to 5,81?m with an average of 4,32?m for birds and 3,11?m to 5,60?m averaging 4,63?m to mammals. As of yet, there isn’t effective treatment against this parasite and considering that it’s a zoonotic disease, preventive measures should be taken to prevent transmission to humans.

    Objective:To assess the prevalence ofLeptospira detected in wildlife and domesticated animals in Jiangxi Province, China, in2009.Methods:Urine samples from 28 buffaloes and kidney samples from50 pigs,50 dogs and38 rats were collected from Fuliang and Shangrao County, Jiangxi Province, China, in October2009. Polymerase chain reaction(PCR) and culture analyses were used to detectLeptospira. The cultured isolates were typed using the microscopic agglutination test (MAT).Results:The results showed that rats potentially serve as the main reservoir of leptospiral infection, followed by dogs. Although16% of rats (6/38) were positive using culture analysis, PCR analysis using the diagnostic primersG1/G2 and B64I/B64II or lipL32 showed identification as50% and24%, respectively, of the rat samples as positive for the presence of leptospiralDNA.Conclusions:PCR-based detection of leptospiralDNA in infected kidney tissues of reservoirs is more efficient when usingG1/G2 primers thanlipL32 primers. However, the latter primers have a potential application for detection in urine samples. The alarmingly high prevalence of leptospiralDNAin the wild rat population near human habitation underscores the utility of routineLeptospira surveillance, preferably usingPCR methods, which are more sensitive than traditional culture-based methods.

    Both social and ecological factors influence population process and structure, with resultant consequences for phenotypic selection on individuals. Understanding the scale and relative contribution of these two factors is thus a central aim in evolutionary ecology. In this study, we develop a framework using null models to identify the social and spatial patterns that contribute to phenotypic structure in a wild population of songbirds. We used automated technologies to track 1053 individuals that formed 73 737 groups from which we inferred a social network. Our framework identified that both social and spatial drivers contributed to assortment in the network. In particular, groups had a more even sex ratio than expected and exhibited a consistent age structure that suggested local association preferences, such as preferential attachment or avoidance. By contrast, recent immigrants were spatially partitioned from locally born individuals, suggesting differential dispersal strategies by phenotype. Our results highlight how different scales of social decision-making, ranging from post-natal dispersal settlement to fission-fusion dynamics, can interact to drive phenotypic structure in animal populations.

    From 1976 to 1999, we conducted a prospective study of overall and cause-specific mortality among the population of 42 villages of south-eastern Senegal. Of 4,228 deaths registered during this period, 26 were brought on by snakebites, 4 by invertebrate stings and 8 by other wild or domestic animals. The average annual mortality rate from snakebite was 14 deaths per 100,000 population. Among persons aged 1 year or more, 0.9% (26/2,880) of deaths were caused by snakebite and this cause represented 28% (26/94) of the total number of deaths by accident. We also investigated the snake fauna of the area. Of 1,280 snakes belonging to 34 species that were collected, one-third were dangerous and the proportion of Viperidae, Elapidae and Atractaspididae was 23%, 11% and 0.6%, respectively. The saw-scaled viper Echis ocellatus was the most abundant species (13.6%). Other venomous species were Causus maculatus (6.5%), Naja katiensis (5.5%), Bitis arietans (2.7%), Elapsoidea trapei (2.4%), Naja nigricollis (1.2%), Naja melanoleuca (1.1%), Atractaspis aterrima (0.4%), Dendroaspis polylepis (0.3%) and Naja haje (0.1%).

  6. Comprehensive Serology Based on a Peptide ELISA to Assess the Prevalence of Closely Related Equine Herpesviruses in Zoo and Wild Animals.

    Directory of Open Access Journals (Sweden)

    Azza Abdelgawad

    Full Text Available Equine herpesvirus type 1 (EHV-1 causes respiratory disorders and abortion in equids while EHV-1 regularly causes equine herpesvirus myeloencephalopathy (EHM, a stroke-like syndrome following endothelial cell infection in horses. Both EHV-1 and EHV-9 infections of non-definitive hosts often result in neuronal infection and high case fatality rates. Hence, EHV-1 and EHV-9 are somewhat unusual herpesviruses and lack strict host specificity, and the true extent of their host ranges have remained unclear. In order to determine the seroprevalence of EHV-1 and EHV-9, a sensitive and specific peptide-based ELISA was developed and applied to 428 sera from captive and wild animals representing 30 species in 12 families and five orders. Members of the Equidae, Rhinocerotidae and Bovidae were serologically positive for EHV-1 and EHV-9. The prevalence of EHV-1 in the sampled wild zebra populations was significantly higher than in zoos suggesting captivity may reduce exposure to EHV-1. Furthermore, the seroprevalence for EHV-1 was significantly higher than for EHV-9 in zebras. In contrast, EHV-9 antibody prevalence was high in captive and wild African rhinoceros species suggesting that they may serve as a reservoir or natural host for EHV-9. Thus, EHV-1 and EHV-9 have a broad host range favoring African herbivores and may have acquired novel natural hosts in ecosystems where wild equids are common and are in close contact with other perissodactyls.

  7. Animals

    International Nuclear Information System (INIS)

    The radionuclides of most concern with respect to contamination of animals after a nuclear accident are radioiodine, radiocaesium and radiostrontium (ICRP 30, 1979). Of the other significant anthropogenic radionuclides likely to be released in most accidents, only small proportions of that ingested will be absorbed in an animals gut, and the main animal products, milk and meat, will not normally be contaminated to a significant extent. Animal products will mostly be contaminated as a result of ingestion of contaminated feed and possibly, but to a much lesser extent, from inhalation (for radioiodine only). Direct external contamination of animals is of little or no consequence in human food production. Radioiodine and radiostrontium are important with respect to contamination of milk; radiocaesium contaminates both milk and meat. The physical and chemical form of a radionuclide can influence its absorption in the animal gut. For example, following the Chernobyl accident radiocaesium incorporated into vegetation by root uptake was more readily absorbed than that associated with the original deposit. The transfer of radiocaesium and radiostrontium to animals will be presented both as transfer coefficients and aggregated transfer coefficients. For most animal meat products, only radiocaesium is important as other radionuclides do not significantly contaminate muscle. Farm animal products are the most important foodstuff determining radiocaesium intake by the average consumer in the Nordic countries. The major potential source of radioiodine and radiostrontium to humans is milk and milk products. Of the different species, the smaller animals have the highest transfer of radiocaesium from fodder to meat and milk. (EG)

    Hepatitis E virus (HEV) infection is recognized as a zoonosis. The prevalence of HEV RNA and anti-HEV antibodies in many animal species has been reported, but the host range of HEV is unclear. The aims of this study were to investigate HEV infection in various animal species and to determine the reservoirs of HEV. Eight hundred twenty-two fecal samples from 17 mammal species and 67 fecal samples from 24 avian species were collected in China and tested for HEV RNA by RT-nPCR. The products of PCR were sequenced and analyzed phylogenetically. The positive rates of HEV RNA isolated from pigs in Beijing, Shandong, and Henan were 33%, 30%, and 92%, respectively, and that from rabbits in Beijing was 5%. HEV RNA was not detectable in farmed foxes, sheep or sika deer, or in wild animals in zoos, including wild boars, yaks, camels, Asiatic black bears, African lions, red pandas, civets, wolves, jackals and primates. Sequence analysis revealed that swine isolates had 97.8%-98.4% nucleotide sequence identity to genotype 4d isolates from patients in Shandong and Jiangsu of China. Phylogenetic analysis showed that swine HEV isolates belong to genotype 4, including subgenotype 4h in Henan and 4d in Beijing and Shandong. The rabbit HEV strains shared 93%-99% nucleotide sequence identity with rabbit strains isolated from Inner Mongolia. In conclusion, swine and rabbits have been confirmed to be the main reservoirs of HEV in China. PMID:26303139

    Proximity data were collected in a captive breeding group of gorillas (Gorilla gorilla gorilla) at the San Diego Wild Animal Park (currently called the San Diego Zoo Safari Park) twice a year (spring and fall periods) for over 12 years, by using a convenient method in which individuals less than 5 m from each animal in the group were recorded by scan sampling, approximately once per hour. Immature females from infancy to young adulthood maintained relatively frequent proximity to both their mothers and the silverback male and spent little time alone (no animals within 10 m), with relatively large individual differences. On the other hand, immature males decreased the time spent near their mothers and the silverback male and increased the time spent alone with increasing age. Therefore, sex differences in proximity to mothers and the silverback male became apparent after late juvenility. Some adult females maintained increased frequency of proximity to the silverback male than that by other females over the 12-year period, indicating the presence of long-term, stable proximity relationships between the silverback male and the adult females. Such long-term, stable proximity relationships were also observed among adult females. Some association patterns reported in wild gorillas, such as frequent proximity between adult females with dependent offspring and the silverback male and close relationships between related females, were not observed in the present study. The idiosyncratic or individual factors influencing some association patterns were easily reflected in captive situations. PMID:24838632

    2012-01-01

    Full Text Available As a result of heightened financial and food insecurity, populations adversely affected by HIV and/or AIDS may be more likely to utilise wild natural resources to supplement their diet and livelihoods. Should this effect be pronounced, HIV and AIDS may pose a serious environmental threat. We explored the hypothesis that the presence of factors in the household, such as chronic illness in and recent mortality of individuals in a high HIV-risk age group, as well as the fostering of orphans, are associated with increased utilisation of wild animal products (WAPs at the household level. We randomly surveyed 519 households from four sites in rural South Africa, recording household socio-economic status, the utilisation of wild animal products and health and demographic factors attributed to HIV or AIDS. Binary logistic regressions were used to test if households with markers of HIV and/or AIDS affliction were more likely to have a higher incidence and frequency of WAP utilisation relative to non-afflicted households, after adjusting for socio-economic and demographic variables. We found that, although households with markers of HIV and/or AIDS were generally poorer and had higher dependency ratios, there was no evidence to support the hypothesis that WAP harvesting was associated with either poverty, or markers of HIV and/or AIDS affliction. Our findings suggest that generalisations about a possible interaction between HIV and/or AIDS and the environment may not uniformly apply to all categories of natural resources or to all user groups.

    Full Text Available The objective of this study was to investigate the frequency of occurrence and variety of intestinal parasites among free-living wild animals. Fecal samples from wild mammals and birds at rehabilitation centers in the states of Mato Grosso do Sul and São Paulo were analyzed by sedimentation and flotation-centrifugation methods. Parasite eggs, oocysts, cysts and/or trophozoites were found in 71% of the samples. Cryptosporidium sp. oocysts were detected in fecal samples from oncillas (Leopardus tigrinus and scaly-headed parrots (Pionus maximiliani. Giardia cysts were identified in the feces of a gray brocket (Mazama gouazoubira. Among the most common parasites found, there were eggs from Toxocara cati, Toxascaris leonina and Ancylostoma tubaeforme, and from Cestoda. Several Enterobius sp. eggs were found in the feces of red howler monkeys (Alouatta seniculus. It can be concluded from this study that despite the small number of samples, the diversity of parasites found was noteworthy. Additional information about parasite endofauna in wild animals is needed, since their presence might suggest that there could be proximity to and interactions with domestic animals and/or humans. In addition, further studies on parasites from free-living wild animals are of prime importance for understanding the intensity of anthropic changes in wild environments.O objetivo deste trabalho foi pesquisar a frequência de ocorrência e a variedade de parasitas intestinais de animais silvestres de vida livre.

    The orientation of elk and other mammals studied in fields with visual and instrumental tracing has obviously hierarchical organization. Animals usually choose general direction headed for distant markers and then select short-distance landmarks. Movements of animals to distant and close landmarks is characterized by almost constant or regularly changing angles between main direction and movement vector. Fragments of trajectories represent left-side or right-side spirals with decreasing or increasing curvature according to the main direction. Three types of spirals differed by average values of initial angles are considered. Orientation to distant landmarks or along direction of movement possesses discrete reaction on the given landmarks and has some characters of iteration process. Special rhythms of activity (rhythms of orientation changing) participate in regulation of changing of movement directions and orientation reactions. They take part in formation of sinusoid, spiral and other trajectories. Rhythmic regulation involves great statistical variability of parameters (lengths, angles, time periods between consecutive orientations) that can be adaptive meaning. Lengths of orientation vectors and trajectory fragments are similar to some linear elements of landscape. Angular parameters of orientation are more variable. The main ones are similar to the angular parameters of Earth rotation. It looks, that orientation parameters evolved under the influence of Sun-Earth compass in inertial field of Earth rotation.

    Full Text Available Leishmania sp. infection was investigated in wild animals from the Ingá Park, in the municipality of Maringá, Paraná state, Brazil, where American cutaneous leishmaniasis (ACL is an endemic disease. Sixty-five mammals, comprising Didelphis albiventris, Cerdocyon thous, Lycalopex vetulus, Cebus apella, Dasyprocta azarae, Dasypus novemcinctus, Procyon cancrivorus and Nasua nasua, were captured. Blood samples were collected for parasite cultivation. Antibodies were investigated by direct agglutination test (DAT using Leishmania (Viannia braziliensis as antigen. Flagellates were observed in blood cultures of 14 (35.9% Didelphis albiventris. Anti-Leishmania antibodies were detected in 31 (51.6% specimens of Cerdocyon thous, Lycalopex vetulus, Cebus apella, Dasyprocta azarae, Procyon cancrivorus and Nasua nasua. These results suggest that Cerdocyon thous and Lycalopex vetulus (crab-eating fox, Cebus apella (capuchin monkey, Dasyprocta azarae (agouti, Procyon cancrivorus (crab-eating raccoon and Nasua nasua (coati play an important role in the ACL transmission cycle in the northwestern region of Paraná, Brazil.

    Full Text Available Twenty-eight isolates of Histoplasma capsulation were obtained from eight species of forest mammals from the States of Amazonas, Pará and Rondônia in the Amazon Region of Brazil. Primary isolates were obtained by inoculating triturated liver and spleen tissue intradermally and intraperito-neally in hamsters. Mycological diagnosis in hamsters presenting lesions was confirmed by histopathology and culture on Sabouraud dextrose-agar. Infected hamsters developed signs of disease within two to nine months; all had disseminated visceral lesions and most also had skin lesions at the sites of inoculation. None of the hamsters inoculated with skin macerates of the original hosts developed histoplasmosis, and histopathological examination of the viscera of the wild hosts failed to reveal H. capsulation. Prevalence of infection was considerably higher in females than in males both for the opossum Didelphis marsupialis and for total wild animals (479 examined. It is proposed that canopy-dwelling mammals may acquire the infection from conidia borne on convective currents in hollow trees with openings at ground-level.Vinte e oito amostras de Histoplasma capsulatum foram obtidas de oito espécies de mamíferos silvestres nos Estados do Amazonas, Pará e Rondônia. Os isolamentos foram feitos mediante inoculação de amostras trituradas de fígado e baço em hamsters por via intradérmica e intraperitoneal. O diagnóstico micológico nos hamsters que apresentaram lesões foi confirmado por histopatologia e cultivo em meio dextrose-agar de Sabouraud. Os hamsters infectados desenvolveram sinais de doença após dois a nove meses; todos apresentaram lesões disseminadas nas vísceras e a maioria apresentou também lesões cutâneas nos locais da inoculação.

    Background:The role of wild foods in combating problems of food shortage is paramount. However, existing approaches to combat food insecurity shock have generally focused on reducing vulnerability via increasing productivity of domesticated foods. In contrast, approaches that enhance resilience mainly through wild food sources have been less focused. This study examined the contribution of wild foods to household resilience to food insecurity in the green famine belt of Ethiopia. Methods: A cross-sectional survey of 220 households was conducted using a structured questionnaire, key informant interviews, and semi-participant observations. Factor analysis was run using SPSS to analyze data. Correlation analysis was used to examine the direction and strength of association between wild foods and the income and food access (IFA), a latent proxy indicator of resilience. Cross-tabulation was also run to determine the proportion of households in each ethno-culture group under each resilience category. Results: The mean amount of wild foods obtained by households was 156.61 kg per household per annum. This was about 5%and 9%of, gross and, net food available from al sources respectively. Wild foods contributed well to household resilience as the factor loading (Factor2=0.467) was large enough and were significantly correlated with IFA (r=0.174). Wild vegetables were the most col ected and consumed type of wild foods constituting 52.4%of total amount of wild foods. The total amount of wild foods was smaller than that of domesticated sources of food. The majority of households (38.6%) reported"reduced source of wild foods"as a reason for this. Smaller proportion of the indigenous (11.2%) than the non-indigenous (34.1%) ethno-culture group reported one or more reasons for their lower level of dependence on wild foods. Conclusion:From the study we concluded that wild foods had important contribution to households' resilience to food shortages and are likely to continue to

Diseases caused by protozoa are rarely found in wild ruminants in nature. Causes of coccidiosis, cryptosporidiosis, toxoplasmosis, sarcocystiosis, giardiasis, babesiosis, and theileriosis have been diagnosed in deer. The most significant helminthoses in wild ruminants are fasciosis, dicrocoeliasis, paramphistomosis, fascioloidosis, cysticercosis, anoplocephalidosis, coenurosis, echinococcosis, pulmonary strongyloidiasis, parasitic gastroenteritis, strongyloidiasis and trichuriasis, with certain differences in the extent of prevalence of infection with certain species. The most frequent ectoparasitoses in wild deer and doe are diseases caused by ticks, mites, scabies mites, and hypoderma. The most represented endoparasitoses in wild boar throughout the world are coccidiosis, balantidiasis, metastrongyloidiasis, verminous gastritis, ascariasis, macracanthorhynchosis, trichinelosis, trichuriasis, cystecercosis, echinococcosis, and less frequently, there are also fasciolosis and dicrocoeliasis. The predominant ectoparasitoses in wild boar are ticks and scabies mites. Knowledge of the etiology and epizootiology of parasitic infections in wild ruminants and wild boar is of extreme importance for the process of promoting the health protection system for animals and humans, in particular when taking into account the biological and ecological hazard posed by zoonotic infections.

  13. Pulmonary hypertension in wild type mice and animals with genetic deficit in KCa2.3 and KCa3.1 channels.

    Christine Wandall-Frostholm

    Full Text Available OBJECTIVE: In vascular biology, endothelial KCa2.3 and KCa3.1 channels contribute to arterial blood pressure regulation by producing membrane hyperpolarization and smooth muscle relaxation. The role of KCa2.3 and KCa3.1 channels in the pulmonary circulation is not fully established. Using mice with genetically encoded deficit of KCa2.3 and KCa3.1 channels, this study investigated the effect of loss of the channels in hypoxia-induced pulmonary hypertension. APPROACH AND RESULT: Male wild type and KCa3.1-/-/KCa2.3T/T(+DOX mice were exposed to chronic hypoxia for four weeks to induce pulmonary hypertension. The degree of pulmonary hypertension was evaluated by right ventricular pressure and assessment of right ventricular hypertrophy. Segments of pulmonary arteries were mounted in a wire myograph for functional studies and morphometric studies were performed on lung sections. Chronic hypoxia induced pulmonary hypertension, right ventricular hypertrophy, increased lung weight, and increased hematocrit levels in either genotype. The KCa3.1-/-/KCa2.3T/T(+DOX mice developed structural alterations in the heart with increased right ventricular wall thickness as well as in pulmonary vessels with increased lumen size in partially- and fully-muscularized vessels and decreased wall area, not seen in wild type mice. Exposure to chronic hypoxia up-regulated the gene expression of the KCa2.3 channel by twofold in wild type mice and increased by 2.5-fold the relaxation evoked by the KCa2.3 and KCa3.1 channel activator NS309, whereas the acetylcholine-induced relaxation - sensitive to the combination of KCa2.3 and KCa3.1 channel blockers, apamin and charybdotoxin - was reduced by 2.5-fold in chronic hypoxic mice of either genotype. CONCLUSION: Despite the deficits of the KCa2.3 and KCa3.1 channels failed to change hypoxia-induced pulmonary hypertension, the up-regulation of KCa2.3-gene expression and increased NS309-induced relaxation in wild-type mice point to a

  16. Threat Perception and Attitudes of Adolescents Towards Re-Introduced Wild Animals: A qualitative study of young learners from affected regions in Germany

    2013-12-01

    Conservation efforts such as the restoration of European bison or the support of wolf immigration into Germany are often socio-scientifically controversial. In many cases, disputes are based on individuals' threat perception and attitudes towards the animal involved. The herewith reported study provides qualitative insights into German adolescents' (n = 31, Mage = 16.6 years) attitudes towards animal reintroduction, their threat and coping appraisal about wildlife and their knowledge of local endangered species. We found that students had rather limited knowledge of local endangered species. After Kellert's categories of animal attitudes, the adolescents showed a strong moralistic view on wildlife return. Naturalistic, ecologistic and utilitarian views were also strongly apparent. According to the Protection Motivation Theory, perceived threats could be identified as threats to animals on the one hand and threats to human interests on the other. Such threat perceptions often lead to a dilemma, which made it difficult to decide upon the priorities of wildlife protection versus protection of human interests. Coping mechanism to reduce threats to human interests as mentioned by the participants included restrictions of the animal as well as strategies that focused on responsibility by humans. Regarding coping mechanism to prevent the species' extinction, participants showed a relatively superficial understanding. Furthermore, we found that participants from regions where wolves are currently immigrating or European bison are being reintroduced showed a more positive understanding of the respective animal. Our findings are discussed in the light of this topic's potential as an example of a real-life socio-scientific issue in classroom discussions.

    Tick-borne viruses infect humans through the bite of infected ticks during opportunistic feeding or through crushing of ticks by hand and, in some instances, through contact with infected viremic animals. The Ijara District, an arid to semiarid region in northern Kenya, is home to a pastoralist community for whom livestock keeping is a way of life. Part of the Ijara District lies within the boundaries of a Kenya Wildlife Service-protected conservation area. Arbovirus activity among mosquitoes, animals, and humans is reported in the region, mainly because prevailing conditions necessitate that people continuously move their animals in search of pasture, bringing them in contact with ongoing arbovirus transmission cycles. To identify the tick-borne viruses circulating among these communities, we analyzed ticks sampled from diverse animal hosts. A total of 10,488 ticks were sampled from both wildlife and livestock hosts and processed in 1520 pools of up to eight ticks per pool. The sampled ticks were classified to species, processed for virus screening by cell culture using Vero cells and RT-PCR (in the case of Hyalomma species), followed by amplicon sequencing. The tick species sampled included Rhipicephalus pulchellus (76.12%), Hyalomma truncatum (8.68%), Amblyomma gemma (5.00%), Amblyomma lepidum (4.34%), and others (5.86%). We isolated and identified Bunyamwera (44), Dugbe (5), Ndumu (2), Semliki forest (25), Thogoto (3), and West Nile (3) virus strains. This observation constitutes a previously unreported detection of mosquito-borne Semliki forest and Bunyamwera viruses in ticks, and association of West Nile virus with A. gemma and Rh. pulchellus ticks. These findings provide additional evidence on the potential role of ticks and associated animals in the circulation of diverse arboviruses in northeastern Kenya, including viruses previously known to be essentially mosquito borne.

  1. Phenotypic variation in metabolism and morphology correlating with animal swimming activity in the wild: relevance for the OCLTT (oxygen- and capacity-limitation of thermal tolerance), allocation and performance models

    Ongoing climate change is affecting animal physiology in many parts of the world. Using metabolism, the oxygen- and capacity-limitation of thermal tolerance (OCLTT) hypothesis provides a tool to predict the responses of ectothermic animals to variation in temperature, oxygen availability and pH in the aquatic environment. The hypothesis remains controversial, however, and has been questioned in several studies. A positive relationship between aerobic metabolic scope and animal activity would be consistent with the OCLTT but has rarely been tested. Moreover, the performance model and the allocation model predict positive and negative relationships, respectively, between standard metabolic rate and activity. Finally, animal activity could be affected by individual morphology because of covariation with cost of transport. Therefore, we hypothesized that individual variation in activity is correlated with variation in metabolism and morphology. To test this prediction, we captured 23 wild European perch (Perca fluviatilis) in a lake, tagged them with telemetry transmitters, measured standard and maximal metabolic rates, aerobic metabolic scope and fineness ratio and returned the fish to the lake to quantify individual in situ activity levels. Metabolic rates were measured using intermittent flow respirometry, whereas the activity assay involved high-resolution telemetry providing positions every 30 s over 12 days. We found no correlation between individual metabolic traits and activity, whereas individual fineness ratio correlated with activity. Independent of body length, and consistent with physics theory, slender fish maintained faster mean and maximal swimming speeds, but this variation did not result in a larger area (in square metres) explored per 24 h. Testing assumptions and predictions of recent conceptual models, our study indicates that individual metabolism is not a strong determinant of animal activity, in contrast to individual morphology, which is

    A total of 69 warthogs, Phacochoerus aethiopicus, were collected from 4 localities within the Kruger National Park, eastern Transvaal Lowveld. These animals harboured 16 nematode species, 2 trematodes, 1 or 2 species of adult cestodes and the larval stages of 4 cestodes. No pattern of seasonal abundance could be determined for any of the helminths. The warthogs were also infested with 3 flea species, 1 louse species, 8 ixodid tick species, 1 argasid tick and the nymphae of a pentastomid. The seasonal abundance of fleas of the genus Echidnophaga, of the sucking louse Haematopinus phacochoeri and the ixodid ticks Amblyomma hebraeum, Rhipicephalus appendiculatus, Rhipicephalus simus and Rhipicephalus zambeziensis was determined.

Combined with GPS positioning and wireless mobile cell network positioning technology, this study researches on the positioning technology of pseudo-cellular wireless mobile network for locating and tracking wild animals. Pseudo-cellular base station location, PCBSL for short, is a mobile communications network based on the principle of a positioning radiolocation and tracking technology, different from wireless mobile communications cellular network positioning, which is a direct application of mobile communication network positioning technology. In the technology of mobile communication, to determine the location of a mobile terminal in the network, it is calculated by the relative position of the device with the different base stations. The position of mobile terminals is determined through base station. The base station divided the whole communication area into many individual cells, the diameter of each cell ranged from tens of meters to thousands of meters mobie terminals actually get online through one of these cells, and then transfer data (voice, text, or multimedia data) via internet. Therefore, when a mobile terminal communicates in the internet, it is always connected to one of the cells, so the position of the mobile terminal can be

    bapA, previously named stm2689, encodes the BapA protein, which, along with cellulose and fimbriae, constitutes biofilms. Biofilms are communities of microorganisms that grow in a matrix of exopolysaccharides and may adhere to living tissues or inert surfaces. Biofilm formation is associated with the ability to persist in different environments, which contributes to the pathogenicity of several species. We analyzed the presence of bapA in 83 strains belonging to 17 serovars of Salmonella enterica subsp. enterica from wildlife in captivity at Culiacan's Zoo and Mazatlán's Aquarium. Each isolate amplified a product of 667 bp, which corresponds to the expected size of the bapA initiator, with no observed variation between different serovars analyzed. bapA gene was found to be highly conserved in Salmonella and can be targeted for the genus-specific detection of this organism from different sources. Since bapA expression improves bacterial proliferation outside of the host and facilitates resistance to disinfectants and desiccation, the survival of Salmonella in natural habitats may be favored. Thus, the risk of bacterial contamination from these animals is increased. PMID:27379195

    International activities with regards the development of methods for assessing impacts on the environment from ionising radiation have been substantial in recent years. In developing these methods, there are requirements (i) to determine the transfer of radionuclides within ecosystems and (ii) to determine background dose-rates arising from the presence of naturally occurring radionuclides, in a satisfactory manner. It has quickly become evident that fulfilling these 2 requirements is not entirely straightforward reflecting a lack of data in many cases. This report specifies exactly where these data-gaps lie through analyses of data generated from the most recent studies conducted internationally on this topic. It is evident that information is limited for numerous radionuclides from U-238 and Th-232 decay series and notably, in view of its importance as a contributor to dose-rates in plants and animals, Po-210. The simple way to rectify these data deficiencies is to organise target field campaigns focusing on particular species and radionuclides where information is lacking. To this end, field sampling has been conducted in a semi-natural mountain ecosystem in Norway and freshwater aquatic systems in Finland. It is envisaged that the data derived from the studies briefly described in this report will provide fundamental information for our understanding of the behaviour and fate of natural decay series radionuclides in terrestrial and aquatic systems and provide the basis for more robust way.

    With increasing population of the wild animals, conflict between the herbivorous wild animals ( such as Tibetan Antelope, Kiangs, and Wild Yaks) and domestic animals for limited grassland resources is becoming increasingly significant in Changtang grassland of Tibet Autonomous Region. The ecological compensation scheme has been considered as one of the important approaches to deal with such problems. Therefore, assessment of the ecological value of wild animals could provide the basis for setting up ecological compensation standard.In this research, we have collected relevant second data including statistics and documents to know current socio-economic conditions of the region, In 2008, a questionnaire survey concerning the protection of ecological environment was conducted among 115 full time government employees in Lasa and Nagqu and among 84 herdsmen in Nyima and Shuanghu Zone. Altogether 199 copies of the questionnaires have been distributed and completed, with 198 valid ones. Key questions designed include the willingness to pay for the protection of wild animals in Changtang area, which late were used for estimation of the non-use values.In this paper we established the valuation system and methodologies for the assessment of ecological service value of the wild animals in Changtang grassland. The Tibetan antelope has been taken as indicative wild animal for the assessment. The value system consists of use value and non-use value. Use value includes direct use value ( commercial value and recreational & entertainment value) and indirect use value (ecological value, cultural and educational value, and aesthetic value, and scientific research value). Non-use value includes existence value, choice value, and heritage value. We estimated the use value mainly through market valuation method and non use value using the contingent valuation method.As there is no market trading for wild animals, so for no corresponding pricing system for valuing the wild animals.

  20. WILD PIG ATTACKS ON HUMANS

    2013-04-12

    Attacks on humans by wild pigs (Sus scrofa) have been documented since ancient times. However, studies characterizing these incidents are lacking. In an effort to better understand this phenomenon, information was collected from 412 wild pig attacks on humans. Similar to studies of large predator attacks on humans, data came from a variety of sources. The various attacks compiled occurred in seven zoogeographic realms. Most attacks occurred within the species native range, and specifically in rural areas. The occurrence was highest during the winter months and daylight hours. Most happened under non-hunting circumstances and appeared to be unprovoked. Wounded animals were the chief cause of these attacks in hunting situations. The animals involved were typically solitary, male and large in size. The fate of the wild pigs involved in these attacks varied depending upon the circumstances, however, most escaped uninjured. Most human victims were adult males traveling on foot and alone. The most frequent outcome for these victims was physical contact/mauling. The severity of resulting injuries ranged from minor to fatal. Most of the mauled victims had injuries to only one part of their bodies, with legs/feet being the most frequent body part injured. Injuries were primarily in the form of lacerations and punctures. Fatalities were typically due to blood loss. In some cases, serious infections or toxemia resulted from the injuries. Other species (i.e., pets and livestock) were also accompanying some of the humans during these attacks. The fates of these animals varied from escaping uninjured to being killed. Frequency data on both non-hunting and hunting incidents of wild pig attacks on humans at the Savannah River Site, South Carolina, showed quantitatively that such incidents are rare.

  3. ADVANCES IN ANIMAL WELFARE FOR FREE-LIVING ANIMALS.

    Science.gov (United States)

    2016-04-01

    Over several decades, animal welfare has grown into its own free-standing field of scientific study, from its early beginnings in laboratory animal research to eventually include exhibited animals and farm animals. While it has always been present to some degree, consideration of animal welfare for free-ranging animals has lagged behind, developing as a field of study in the last 20 yr or so. Part of that increase was that animal welfare legislation was finally applied to studies being done on free-ranging animals. But it is the appreciation by the biologists and veterinarians working on wild animals, in which the quality of their results is largely controlled by the quality of the animals they use in their studies, which has resulted in increased attention to the well-being or welfare of the animals that they use. Other important influences driving the recognition of wildlife welfare have been changes in the public's expectations of how wild animals are dealt with, a shift in focus of wildlife professionals from managing animals that can be hunted or angled to include nongame species, the decrease in participation in hunting and fishing by members of the public, and the entry of large numbers of women into fish and wildlife agencies and departments and into veterinary medicine. Technical improvements have allowed the safe capture and handling of large or dangerous animals as immobilization drugs and equipment have been developed. The increasing use of sedating drugs allows for handling of animals with reduced stress and other impacts. A number of topics, such as toe-clipping, branding, defining which taxa can or cannot feel pain, catch-and-release fishing, and more, remain controversial within wildlife science. How we treat the wild animals that we deal with defines who we are as wildlife professionals, and animal welfare concerns and techniques for free-ranging animals will continue to develop and evolve.

    The results are given of a study on the role of wildlife in the transmission of Echinococcus granulosus in the Turkana and Narok Districts of Kenya. A total of 76 wild carnivores belonging to three separate species was examined from Turkana District. Echinococcus adults were found in 11 of 38 silver-backed jackals (Canis mesomelas) and in six of 22 golden jackals (Canis aureus). This is the first record of golden jackals being infected with this parasite in Kenya. None of 16 spotted hyaenas (Crocuta crocuta) harboured the parasite. Morphological features of the parasites obtained from the jackals were compared with material obtained from dogs in the same area. No morphological differences were recorded when this material was compared with data reported by others, hence the Turkana material belonged to the single species E. granulosus. Three silver-backed jackals and three puppies (Canis familiaris) were successfully infected with protoscolices obtained from a hydatid cyst surgically removed from a Turkana patient. Three spotted hyaenas fed the same material failed to become infected. None of 152 wild herbivores of five species examined in Turkana harboured hydatid cysts. The natural jackal infections in this District are thought to be incidental and dependent on the continuance of the domestic cycle. The role of the Turkana themselves in the perpetuation of the cycle is discussed. Twenty-six wild herbivores of six species were examined for hydatid cysts, in Narok District; hydatids were found in three wildebeest (Connochaetes taurinus) and a single topi (Damaliscus korrigum). The discovery of fertile cysts in wildebeest and the reported infections in lions (Panthera leo), Cape hunting dogs (Lycaon pictus) and silver-backed jackals, support previous evidence of the existence of a wildlife cycle in the Masailand and Serengeti regions of East Africa. The relationship of this cycle to the domestic cycle operating in the same area is unclear and requires further

    Full Text Available The paper presents the most important parasitic infections of wild rabbits and hares, which harmful effect in this animal population is manifested as a gradual weakening of the immune system, reduction in fertility, weight loss and constant exhaustion. Order of Lagomorpha (hares or lagomorphs belongs to superorder of higher mammals which includes the family of rabbits (Leporidae which are represented in Europe as well as the family of whistleblowers (Ochotonidae which live only in North America and Northern regions of Asia. The most important representatives of Leporidae family are European hare (Lepus europeus and wild rabbit (Oryctolagus cuniculus. The most important endoparasitosis of hares and wild rabbits are: coccidiosis, encephalitozoonosis (nosemosis, toxoplasmosis, sarcocystosis, giardiasis, cryptosporidiosis, protostrongylosis, trichostrngylodosis, passalurosis, anoplocephalidosis, cysticercosis and fasciolosis. The most frequent ectoparasites of rabbits and wild hares are fleas, lice and ticks. Reduction in hare population, which is noticed in whole Europe including Serbia, is caused by changed living conditions, quantitatively and qualitatively insufficient nutrition, increased use of herbicides as well as various infectious diseases and the diseases of parasitic etiology. Since wild rabbits and hares pose a threat to health of domestic rabbits and people, knowledge of parasitic fauna of these wild animals is of extreme epizootiological and epidemiological importance.

  6. CHARACTERIZATION OF WILD PIG VEHICLE COLLISIONS

    2007-05-23

    Wild pig (Sus scrofa) collisions with vehicles are known to occur in the United States, but only minimal information describing these accidents has been reported. In an effort to better characterize these accidents, data were collected from 179 wild pig-vehicle collisions from a location in west central South Carolina. Data included accident parameters pertaining to the animals involved, time, location, and human impacts. The age structure of the animals involved was significantly older than that found in the population. Most collisions involved single animals; however, up to seven animals were involved in individual accidents. As the number of animals per collision increased, the age and body mass of the individuals involved decreased. The percentage of males was significantly higher in the single-animal accidents. Annual attrition due to vehicle collisions averaged 0.8 percent of the population. Wild pig-vehicle collisions occurred year-round and throughout the 24-hour daily time period. Most accidents were at night. The presence of lateral barriers was significantly more frequent at the collision locations. Human injuries were infrequent but potentially serious. The mean vehicle damage estimate was $1,173.

    Raccoons (Procyon lotor) are common, widely distributed animals that frequently come into contact with wild waterfowl, agricultural operations, and humans. Serosurveys showed that raccoons are exposed to avian influenza virus. We found antibodies to a variety of influenza virus subtypes (H10N7, H4N6, H4N2, H3, and H1) with wide geographic variation in seroprevalence. Experimental infection studies showed that raccoons become infected with avian and human influenza A viruses, shed and transmit virus to virus-free animals, and seroconvert. Analyses of cellular receptors showed that raccoons have avian and human type receptors with a similar distribution as found in human respiratory tracts. The potential exists for co-infection of multiple subtypes of influenza virus with genetic reassortment and creation of novel strains of influenza virus. Experimental and field data indicate that raccoons may play an important role in influenza disease ecology and pose risks to agriculture and human health.

  11. Wild genius - domestic fool? Spatial learning abilities of wild and domestic guinea pigs

    Directory of Open Access Journals (Sweden)

    2010-03-01

    Full Text Available Abstract Background Domestic animals and their wild relatives differ in a wide variety of aspects. The process of domestication of the domestic guinea pig (Cavia aperea f. porcellus, starting at least 4500 years ago, led to changes in the anatomy, physiology, and behaviour compared with their wild relative, the wild cavy, Cavia aperea. Although domestic guinea pigs are widely used as a laboratory animal, learning and memory capabilities are often disregarded as being very scarce. Even less is known about learning and memory of wild cavies. In this regard, one striking domestic trait is a reduction in relative brain size, which in the domesticated form of the guinea pig amounts to 13%. However, the common belief, that such a reduction of brain size in the course of domestication of different species is accomplished by less learning capabilities is not at all very well established in the literature. Indeed, domestic animals might also even outperform their wild conspecifics taking advantage of their adaptation to a man-made environment. In our study we compared the spatial learning abilities of wild and domestic guinea pigs. We expected that the two forms are different regarding their learning performance possibly related to the process of domestication. Therefore wild cavies as well as domestic guinea pigs of both sexes, aged 35 to 45 days, were tested in the Morris water maze to investigate their ability of spatial learning. Results Both, wild cavies and domestic guinea pigs were able to learn the task, proving the water maze to be a suitable test also for wild cavies. Regarding the speed of learning, male as well as female domestic guinea pigs outperformed their wild conspecifics significantly. Interestingly, only domestic guinea pigs showed a significant spatial association of the platform position, while other effective search strategies were used by wild cavies. Conclusion The results demonstrate that domestic guinea pigs do not at all

  12. Osmoregulation in wild and captive West Indian manatees (Trichechus manatus).

    The ability of West Indian manatees (Trichechus manatus latirostris and Trichechus manatus manatus) to inhabit both freshwater and marine habitats presents an interesting model to study osmoregulation in sirenians. Blood samples were analyzed from manatees held in fresh- and saltwater and from wild animals captured in fresh-, brackish, and saltwater for concentrations of aldosterone, arginine vasopressin, plasma renin activity, Na+, K+, Cl-, and osmolality. Two separate experiments were also conducted on captive animals to evaluate osmoregulatory responses to acute saltwater exposure and freshwater deprivation. Spurious differences were observed in plasma electrolyte and osmolality among the captive and wild groups. Wild brackish water animals exhibited the highest vasopressin concentrations, while wild freshwater manatees had the highest aldosterone levels. A significant correlation between mean vasopressin and osmolality was demonstrated for captive and wild animals. When freshwater animals were acutely exposed to saltwater, osmolality, Na+, and Cl- increased 5.5%, 8.0%, and 14%, respectively, while aldosterone decreased 82.6%. Saltwater animals deprived of freshwater exhibited an almost twofold increase in aldosterone during the deprivation period and a fourfold decrease when freshwater was again provided. Within this group, osmolality increased significantly by 3.4% over the course of the study; however, electrolytes did not change. The lack of consistent differences in electrolyte and osmolality among wild and captive groups suggests that manatees are good osmoregulators regardless of the environment. The high aldosterone levels in wild freshwater animals may indicate a need to conserve Na+, while the high vasopressin levels in wild brackish-water manatees suggest an antidiuretic state to conserve water. Vasopressin levels appear to be osmotically mediated in manatees as in other mammals. PMID:9678505

    Don Griffin showed more than 50 years ago that bats echolocate for orientation and to capture prey. Experiments also demonstrated that captive dolphins can echolocate; more recent work parallels Griffin's work with bats in the wild. Digital acoustic recording tags were attached to sperm and beaked whales, Ziphius cavirostris and Mesoplodon densirostris, to record outgoing clicks and incoming echoes. The sperm whale data show echoes from the sea surface and seafloor, which are probably used for orientation and obstacle avoidance. When diving, sperm whales adjust their interclick interval as they change their pitch angle, consistent with the hypothesis that they are echolocating on a horizontal layer at the depth at which they will feed. This suggests that they may be listening for volume reverberation to select a prey patch. The beam pattern of sperm whales includes a narrow, forward-directed high-frequency beam probably used for prey detection, and a broader, backward-directed lower-frequency beam probably used for orientation. Beaked whales produce directional clicks with peak frequencies in the 25-40-kHz region. Echoes from individual prey items have been detected from clicks of beaked whales. This opens a new window into the study of how animals use echolocation to forage in the wild.

    Infanticidal behaviour is wide-spread among animals of various taxonomic groups, but has not previously been reported in European wild boars, which are commonly kept in enclosures in Sweden and Finland for meat and recreation purposes. We studied the behaviour of wild boars in one enclosure during three reproductive seasons. Non-maternal infanticide was documented in 14 out of 22 litters, causing the deaths of all piglets in all but one affected litters. Infanticide was typically performed du...

    In boars, sexually motivated mounting can not only cause problems such as lameness, but penile injuries are also reported. The relevance of penis biting in boars is discussed controversially, but reliable data is missing. In the present study, boars ( n = 435) and barrows ( n = 85) from experimental farms were therefore evaluated for scars, fresh wounds and severe injuries of the penis. Similarly, 321 boars from 11 farms specializing in pork production with boars, and 15 sexually mature wild boars from the hunting season of 2015/16 were included in the study. In domestic boars, a high incidence of penile injuries was obvious (76.6%-87.0% of animals with scars and/or wounds at experimental farms, 64.0%-94.9% at commercial farms). The number of boars with severe injuries was in a similar range in both groups (7.3% vs. 9.3%). At commercial farms, the number of scars but not that of fresh wounds increased per animal with age by 0.3 per week. Moreover, raising boars in mixed groups led to about a 1.5 times higher number of scars than in single-sex groups. In wild boars, a considerable proportion of animals (40%) revealed penile injuries, which were even severe in three animals. We therefore conclude that penis biting is a highly relevant and severe welfare problem in the male pig population, but this phenomenon is not limited to intensive production systems. PMID:27023619

    We measured the hearing abilities of seven wild beluga whales (Delphinapterus leucas) during a collection-and-release experiment in Bristol Bay, AK. Here we summarize the methods and initial data from one animal and discuss the implications of this experiment. Audiograms were collected from 4 to 150 kHz. The animal with the lowest threshold heard best at 80 kHz and demonstrated overall good hearing from 22 to 110 kHz. The robustness of the methodology and data suggest that the auditory evoked potential audiograms can be incorporated into future collection-and-release health assessments. Such methods may provide high-quality results for multiple animals, facilitating population-level audiograms and hearing measures in new species. PMID:26611025

    2011-02-01

    The question of whether animals possess 'cultures' or 'traditions' continues to generate widespread theoretical and empirical interest. Studies of wild chimpanzees have featured prominently in this discussion, as the dominant approach used to identify culture in wild animals was first applied to them. This procedure, the 'method of exclusion,' begins by documenting behavioural differences between groups and then infers the existence of culture by eliminating ecological explanations for their occurrence. The validity of this approach has been questioned because genetic differences between groups have not explicitly been ruled out as a factor contributing to between-group differences in behaviour. Here we investigate this issue directly by analysing genetic and behavioural data from nine groups of wild chimpanzees. We find that the overall levels of genetic and behavioural dissimilarity between groups are highly and statistically significantly correlated. Additional analyses show that only a very small number of behaviours vary between genetically similar groups, and that there is no obvious pattern as to which classes of behaviours (e.g. tool-use versus communicative) have a distribution that matches patterns of between-group genetic dissimilarity. These results indicate that genetic dissimilarity cannot be eliminated as playing a major role in generating group differences in chimpanzee behaviour. PMID:20719777

  6. Ecotoxicology of Wild Mammals

    Science.gov (United States)

    2001-01-01

    An international group of 32 scientists has critically reviewed the scientific literature on exposure and effects of environmental contaminants in wild mammals. The underlying theme of this text is encompassed by the following four questions: What exactly do we know about environmental contaminants in mammals? What are the commonalities and differences between mammal orders/species in the effects that contaminants have? How and to what degree of accuracy can we predict the adverse effects of environmental contaminants on mammalian wildlife? How significant are contaminant insults compared with other density-independent and -dependent factors such as habitat loss, climatic factors and disease? The book is organized three topical sections including introductory chapters that provide a background on environmental contaminants and the mammalian orders, eight taxonomic chapters discussing all aspects of the exposure to and effects of contaminants in mammalian orders, and four thematic chapters that review and discuss generic issues including biomarkers, prediction and extrapolation of exposure and effects, hazard and risk assessment, and the relative significance of contaminants on mammals compared with other commonly encountered stressors. A final a summary chapter identifies phylogenetic trends, critical data gaps, and overarching research needs. Although the absolute number of toxicological studies in domesticated and wild mammals eclipses that wildlife species, a detailed examination of our knowledge base reveals that information for 'wild' birds is actually greater than that for 'wild' mammals. Of the various mammalian taxa, ecotoxicological data is most noticeably lacking for marsupials and monotremes. In contrast, rodents (comprising 43% of all mammal species) have been studied extensively, despite evidence of their tolerance to some organochlorine compounds, rodenticides, and even radionuclides. Mammalian species at greatest risk of exposure include those that

    1998-01-01

    Under the pressure of a public vote in Switzerland (7 June 1998) on an initiative to ban the production, use and patenting of transgenic animals, their value for biomedical research and development is intensely debated. In addition, the Swiss legislation has adopted (1992) a constitutional obligation to "take into account the dignity of creatures". The term "dignity of creatures", however, can be interpreted in anthropocentric or biocentric ways. The government has now formulated the legal implications of this term for transgenic animals and plants in various laws including the animal and environmental protection laws. This paper gives arguments for a fair evaluation of trangenic animals from an animal welfare point of view where not only the costs of animal suffering must be considered but also the probability of potential benefit for man. A self-confident research community should allow such an evaluation procedure even in view of an outcome which could ban many uses of transgenic animals PMID:11208266

    Ecological variation influences the appearance and maintenance of tool use in animals, either due to necessity or opportunity, but little is known about the relative importance of these two factors. Here, we combined long-term behavioural data on feeding and travelling with six years of field experiments in a wild chimpanzee community. In the experiments, subjects engaged with natural logs, which contained energetically valuable honey that was only accessible through tool use. Engagement with the experiment was highest after periods of low fruit availability involving more travel between food patches, while instances of actual tool-using were significantly influenced by prior travel effort only. Additionally, combining data from the main chimpanzee study communities across Africa supported this result, insofar as groups with larger travel efforts had larger tool repertoires. Travel thus appears to foster tool use in wild chimpanzees and may also have been a driving force in early hominin technological evolution. PMID:27431611

    Simple Summary Male pigs raised for pork production on experimental and commercial farms were evaluated for scars, fresh wounds and severe injuries of the penis. A high incidence of penile injuries (64.0%–94.9% of the animals/farm) was found in boars but not in barrows (castrated males) with even severe wounds in 5.2% to 9.3% of the boars. A similar evaluation of 15 free-ranging wild boars also revealed a considerable proportion of animals with penile injuries. Thus, penis biting is a highly relevant and severe welfare problem in boars which is not limited to intensive production systems. Abstract In boars, sexually motivated mounting can not only cause problems such as lameness, but penile injuries are also reported. The relevance of penis biting in boars is discussed controversially, but reliable data is missing. In the present study, boars (n = 385) and barrows (n = 85) from experimental farms were therefore evaluated for scars, fresh wounds and severe injuries of the penis.

    Habituation to human observers is an essential tool in animal behaviour research. Habituation occurs when repeated and inconsequential exposure to a human observer gradually reduces an animal's natural aversive response. Despite the importance of habituation, little is known about the psychological mechanisms facilitating it in wild animals. Although animal learning theory offers some account, the patterns are more complex in natural than in laboratory settings, especially in large social groups in which individual experiences vary and individuals influence each other. Here, we investigate the role of social learning during the habituation process of a wild chimpanzee group, the Waibira community of Budongo Forest, Uganda. Through post hoc hypothesis testing, we found that the immigration of two well-habituated, young females from the neighbouring Sonso community had a significant effect on the behaviour of non-habituated Waibira individuals towards human observers, suggesting that habituation is partially acquired via social learning.

    Pavlov and Thorndike pioneered the experimental study of animal learning and provided psychologists with powerful tools to unveil its underlying mechanisms. Today's research developments and theoretical analyses owe much to the pioneering work of these early investigators. Nevertheless, in the evolution of our knowledge about animal learning, some initial conceptions have been challenged and revised. We first review the original experimental procedures and findings of Pavlov and Thorndike. Next, we discuss critical research and consequent controversies which have greatly shaped animal learning theory. For example, although contiguity seemed to be the only condition that is necessary for learning, we now know that it is not sufficient; the conditioned stimulus (CS) also has to provide information about the occurrence of the unconditioned stimulus (US). Also, animals appear to learn different things about the same stimuli when circumstances vary. For instance, when faced with situations in which the meaning of a CS changes, as in the case of acquisition and later extinction, animals seem to preserve the original knowledge (CS-US) in addition to learning about the new conditions (CS-noUS). Finally, we discuss how parallels among Pavlovian conditioning, operant conditioning, and human causal judgment suggest that causal knowledge may lie at the root of both human and animal learning. All of these empirical findings and theoretical developments prove that animal learning is more complex and intricate than was once imagined. Copyright © 2009 John Wiley & Sons, Ltd.

    An animal's behavior is affected by its cognitive abilities, which are, in turn, a consequence of the environment in which an animal has evolved and developed. Although behavioral ecologists have been studying animals in their natural environment for several decades, over much the same period animal cognition has been studied almost exclusively in the laboratory. Traditionally, the study of animal cognition has been based on well-established paradigms used to investigate well-defined cognitive processes. This allows identification of what animals can do, but may not, however, always reflect what animals actually do in the wild. As both ecologists and some psychologists increasingly try to explain behaviors observable only in wild animals, we review the different motivations and methodologies used to study cognition in the wild and identify some of the challenges that accompany the combination of a naturalistic approach together with typical psychological testing paradigms. We think that studying animal cognition in the wild is likely to be most productive when the questions addressed correspond to the species' ecology and when laboratory cognitive tests are appropriately adapted for use in the field. Furthermore, recent methodological and technological advances will likely allow significant expansion of the species and questions that can be addressed in the wild. PMID:26781051

  15. REVIEW: TIBET WILD

    Full Text Available Review of: George B. Schaller. 2012. Tibet Wild: A Naturalist's Journeys on the Roof of the World. Washington, D.C.; Island Press George Schaller's remarkable career spans nearly six decades of work resulting in field studies of wildlife in the most remote regions, including pioneering investigations on four continents. More than half of that time was spent involved with studies of the wildlife of the Tibetan Plateau and neighboring regions. Following each new phase of his career, from his work on mountain gorillas in Rwanda, tigers in India, lions on the Serengeti, wild sheep in the Himalayas, and Tibetan antelope and other wildlife on the Tibetan steppes, he has made the time to publish a book on each of his expeditions – or more exactly, two (see full list in Appendix. One is always a scholarly monograph full of data, tables, and maps, the other a popular account for the general public. These paired volumes are usually published within one year of each other, and there have been six such pairings so far. For example, Schaller's classic the Mountain Monarchs: Wild Sheep and Goats of the Himalaya was published in 1978; in 1980, he published Stones of Silence: Journeys in the Himalaya; in 1997 he published the popular Tibet's Hidden Wilderness: Wildlife and Nomads of the Chang Tang Reserve; and the next year, 1998, saw the appearance of his scholarly monograph Wildlife of the Tibetan Steppe. By this accounting, this latest book, coming fifteen years after the last, seems an outlier – perhaps we can expect a scholarly monograph on Schaller's work in Tibet and Central Asia soon. And yet, this current book is scholarly enough, being filled with facts, figures, maps, and even data tables. Perhaps it is meant to pair with the highly personal A Naturalist and Other Beasts, a collection of essays that Schaller has written over the past fifty years. However, this new book has few references and is interspersed with anecdotes, bibliographic

    In Switzerland sarcoptic mange is frequent in free-ranging wild carnivores but until recent years no cases had been recorded in wild ungulates. Since 2010, cases have been observed in wild boar in the cantons of Solothurn, Tessin and Thurgau. Here, we report the detection of mange-like skin lesions in wild boars by photo-trapping and the post-mortem findings in 6 culled animals presenting different stages of the disease. Potential sources of infection include mangy red foxes, outdoor domestic pigs and wild boars from surrounding countries. Disease spread in the wild boar population may become relevant not only for wildlife but also for domestic pig health in the future if piggeries' biosecurity is insufficient to prevent interactions with wild boar.

  1. Wild Boar Research – A Never Ending Story?

    Full Text Available Wild boar science is changing a lot. The species wild boar (Sus scrofa, once threatened, is one of the latest domesticated species. Wild boar is so successful that currently it causes strong economic and ecological damages all over the world. The interest in Sus scrofa continues to grow rapidly, not only within its native range, but also in all other continents where wild boar and feral pigs have been introduced. Environmentally sensitive and adaptative management plus conservation of wild boar, feral pigs and other suids is of increasing concern to conservation biologists, wildlife managers, veterinarians, policy makers and the general public. Important advances in research may help managing wild boar as a pest and other suids as threatened species. Also a good exchange with stakeholders is of huge importance within wildlife management. In this special issue of Wildlife Biology in Practice some results from the 9th International Symposium on Wild Boar and other Suids as well as additional publications on wild boar are centralised. All together 110 participants from 24 countries took part at the 9th ISWB in Hannover, Germany. The main part of the 59 presentations focused on wild boar management and monitoring (29 contributions. These numbers points out the importance of wild boar in all parts of its current distribution area. Everywhere populations are increasing (with some very few exceptions. In many of these regions economic problems, mainly by agricultural damages, road accidents and animal diseases are the main drivers for scientific interests. Recently many researchers try to establish, or even to create, reliable and practical census methods. Only with reliable data on numbers, reproduction, im- and emigration as well as mortality rates, managers will be able to know the efficiency of management methods. Even if a lot of effort is done, it looks like we are still far away from successful control of wild boar or feral pigs’ populations

    C-peptide of insulin presents a promising new tool for behavioral ecologists that allows for regular, noninvasive assessment of energetic condition in wild animals. C-peptide is produced on an equimolar basis with insulin, thus is indicative of the body's response to available glucose and, with repeated measurement, provides a biomarker of energy balance. As yet, few studies have validated the efficacy of C-peptide for monitoring energy balance in wild animals. Here, we assess seasonal and in...

No entanto, os avanços têm sido mais lentos do que antecipados, especialmente em razão da dificuldade na identificação dos genes responsáveis pelas características fenotípicas de interesse zootécnico. Três estratégias principais têm sido utilizadas para identificar esses genes - mapeamento de QTL, genes candidatos e sequenciamento de DNA e mRNA - e cada uma tem suas vantagens e limitações. O mapeamento de QTL permite determinar as regiões genômicas que contêm genes, mas o intervalo de confiança do QTL pode ser grande e conter muitos genes. A estratégia de genes candidatos é limitada por causa do conhecimento ainda restrito das funções de todos os genes. Os sequenciamentos de genomas e de sequências expressas podem auxiliar na identificação da posição de genes e de vias metabólicas associadas à característica de interesse. A integração dessas estratégias por meio do desenvolvimento de programas de bioinformática permitirá a identificação de novos genes de interesse zootécnico. Assim, os programas de melhoramento genético se beneficiarão pela inclusão da informação obtida diretamente do DNA na avaliação do mérito genético dos plantéis disponíveis.Animal biotechnology is providing new tools for animal breeding and genetics and thus contributing to advances in production efficiency and quality of animal products.

    In the spring of 2007, seven raccoon dogs and a weasel were captured near the city of Tanabe in Wakayama prefecture, Japan. The causative agent of the animals' death 1-2 days after capture was identified as canine distemper virus (CDV) by virus isolation, immunostaining with an anti-CDV polyclonal antibody, and a commercially available CDV antigen-detection kit. Sequence analysis of hemagglutinin genes indicated the isolated viruses belong to genotype Asia-1 and possess the substitution from tyrosine (Y) to histidine (H) at position 549 that is associated with the spread of CDV to non-canine hosts. A serosurvey for CDV was then conducted among wild animals in the region. The animals assayed consisted of 104 raccoons, 41 wild boars, 19 raccoon dogs, five Sika deer, two badgers, one weasel, one marten, one Siberian weasel and one fox. Virus-neutralization (VN) tests showed that, except for fox and weasel, all of the species assayed had VN antibodies to CDV. Interestingly, 11 of the 41 wild boars (27%) and two of the five Sika deer assayed possessed VN antibodies to CDV. These findings indicate that CDV infection was widespread among wild mammals during this epizootic. PMID:21840141

  9. The control of classical swine fever in wild boar

    2015-11-01

    Full Text Available Classical swine fever (CSF is a viral disease with severe economic consequences for domestic pigs. Natural hosts for the CSF virus (CSFV are members of the family Suidae, i.e. Eurasian wild boar (sus scrofa are also susceptible. CSF in wild boar poses a serious threat to domestic pigs. CSFV is an enveloped RNA virus belonging to the pestivirus genus of the Flaviviridae family. Transmission of the infection is usually by direct contact or by feeding of contaminated meat products. In recent decades CSF has been successfully eradicated from Australia, North America, and the European Union. In areas with dense wild boar populations CSF tends to become endemic whereas it is often self-limiting in small, less dense populations. In recent decades eradication strategies of CSF in wild boar have been improved considerably. The reduction of the number of susceptible animals to a threshold level where the basic reproductive number is R0<1 is the major goal of all control efforts. Depending on the epidemiological situation, hunting measures combined with strict hygiene may be effective in areas with a relatively low density of wild boar. Oral immunization was shown to be highly effective in endemic situations in areas with a high density of wild boar.

    As travellers seek ever more exotic destinations they are more likely to encounter dangerous animals. Compared to risks such as AIDS, traffic accidents and malaria, the risk is not so great; many travellers are, however, concerned about this and those who give pre-travel vaccines and advice should know something about it. This article is mainly based on medical and zoological textbooks. Venomous stings and bites may be prevented by adequate clothing and by keeping safe distance to the animals. Listening to those who live in the area is of course important. Travellers should not carry antisera with them, but antisera should be available at local hospitals. It should be borne in mind that plant eaters cause just as many deaths as large predators. In some cases it is necessary to carry a sufficiently powerful firearm. PMID:12555616

    2011-07-01

    In 1997, cutaneous papillomatosis caused by Florida manatee (Trichechus manatus latirostris [Tm]) papillomavirus 1 (TmPV1) was detected in seven captive manatees at the Homosassa Springs Wildlife State Park, Florida, USA, and, subsequently, in two wild manatees from the adjacent Homosassa River. Since then, papillomatosis has been reported in captive manatees housed in other locations, but not in wild animals. To determine TmPV1 antibody prevalence in captive and wild manatees sampled at various locations throughout Florida coastal regions, virus-like particles, composed of the L1 capsid protein of TmPV1, were generated with a baculovirus expression system and used to measure anti-TmPV1 antibodies in an enzyme-linked immunosorbent assay. Serologic analysis of 156 manatees revealed a TmPV1 antibody prevalence of 26.3%, with no significant difference between captive (n=39) and wild (n=117) manatees (28.2% and 25.6%, respectively). No antibody-positive wild animal showed PV-induced cutaneous lesions, whereas papillomatosis was observed in 72.7% of antibody-positive captive manatees. Our data indicate that Florida manatees living in the wild are naturally infected by TmPV1 but rarely show TmPV1-induced papillomatosis. Hence, it appears that the wild population would not be harmed in a case of contact with captive animals without visible lesions and productive infections, which could be thus released into the wild.

  17. WILD PIGS: BIOLOGY, DAMAGE, CONTROL TECHINQUES AND MANAGEMENT

    Energy Technology Data Exchange (ETDEWEB)

    Mayer, John; Brisbin, I. Lehr

    2009-12-31

    The existence of problems with wild pigs (Sus scrofa) is nothing new to the Western Hemisphere. Damage by these introduced animals was reported as far back as 1505 by the early Spanish colonies in the Caribbean, where wild pigs were killing the colonists cattle. Droves of these animals also ravaged cultivated crops of maize and sugarcane on islands in the West Indies during this same time period. These wild pigs reportedly were very aggressive and often attacked Spanish soldiers hunting rebellious Indians or escaped slaves on these islands, especially when these animals were cornered. The documentation of such impacts by introduced populations of this species in the United States has subsequently increased in recent years, and continued up through the present (Towne and Wentworth. 1950, Wood and Barrett 1979, Mayer and Brisbin 1991, Dickson et al. 2001). In spite of a fairly constant history in this country since the early 1900s, wild pigs have had a dramatic recent increase in both distribution and numbers in the United States. Between 1989 and 2009, the number of states reporting the presence of introduced wild pigs went from 19 up to as many as 44. This increase, in part natural, but largely manmade, has caused an increased workload and cost for land and resource managers in areas where these new populations are found. This is the direct result of the damage that these introduced animals do. The cost of both these impacts and control efforts has been estimated to exceed a billion dollars annually (Pimentel 2007). The complexity of this problem has been further complicated by the widespread appeal and economic potential of these animals as a big game species (Tisdell 1982, Degner 1989). Wild pigs are a controversial problem that is not going away and will likely only get worse with time. Not only do they cause damage, but wild pigs are also survivors. They reproduce at a rate faster than any other mammal of comparable size, native or introduced; they can eat just

    The development of a new anticancer drug is a long, complex and multistep process which is supervised by regulatory authorities from the different countries all around the world [1]. Application of a new drug for admission to the market is supported by preclinical and clinical data, both including the determination of pharmacodynamics, toxicity, antitumour activity, therapeutic index, etc. As preclinical studies are associated with high cost, optimization of animal experiments is crucial for the overall development of a new anticancer agent. Moreover, in vivo efficacy studies remain a determinant panel for advancement of agents to human trials and thus, require cautious design and interpretation from experimental and ethical point of views.

    2008-07-01

    Full Text Available Abstract Background Functional genomics has particular promise in silkworm biology for identifying genes involved in a variety of biological functions that include: synthesis and secretion of silk, sex determination pathways, insect-pathogen interactions, chorionogenesis, molecular clocks. Wild silkmoths have hardly been the subject of detailed scientific investigations, owing largely to non-availability of molecular and genetic data on these species. As a first step, in the present study we generated large scale expressed sequence tags (EST in three economically important species of wild silkmoths. In order to make these resources available for the use of global scientific community, an EST database called 'WildSilkbase' was developed. Description WildSilkbase is a catalogue of ESTs generated from several tissues at different developmental stages of 3 economically important saturniid silkmoths, an Indian golden silkmoth, Antheraea assama, an Indian tropical tasar silkmoth, A. mylitta and eri silkmoth, Samia cynthia ricini. Currently the database is provided with 57,113 ESTs which are clustered and assembled into 4,019 contigs and 10,019 singletons. Data can be browsed and downloaded using a standard web browser. Users can search the database either by BLAST query, keywords or Gene Ontology query. There are options to carry out searches for species, tissue and developmental stage specific ESTs in BLAST page. Other features of the WildSilkbase include cSNP discovery, GO viewer, homologue finder, SSR finder and links to all other related databases. The WildSilkbase is freely available from http://www.cdfd.org.in/wildsilkbase/. Conclusion A total of 14,038 putative unigenes was identified in 3 species of wild silkmoths. These genes provide important resources to gain insight into the functional and evolutionary study of wild silkmoths. We believe that WildSilkbase will be extremely useful for all those researchers working in the areas of

    Ecological variation influences the appearance and maintenance of tool use in animals, either due to necessity or opportunity, but little is known about the relative importance of these two factors. Here, we combined long-term behavioural data on feeding and travelling with six years of field experiments in a wild chimpanzee community. In the experiments, subjects engaged with natural logs, which contained energetically valuable honey that was only accessible through tool use. Engagement with the experiment was highest after periods of low fruit availability involving more travel between food patches, while instances of actual tool-using were significantly influenced by prior travel effort only. Additionally, combining data from the main chimpanzee study communities across Africa supported this result, insofar as groups with larger travel efforts had larger tool repertoires. Travel thus appears to foster tool use in wild chimpanzees and may also have been a driving force in early hominin technological evolution.

    Full Text Available FUNDAMENTOS: Nos últimos anos, existe um aumento progressivo do contato de moradores urbanos com ambientes selvagens devido a atividades de lazer. Com isso, algumas dermatites pouco conhecidas podem ser observadas nas clínicas privadas e ambulatórios dermatológicos, especialmente nos inícios de semana e finais de férias. OBJETIVOS: Obter e fornecer informações para dermatologistas sobre o problema. PACIENTES E MÉTODOS: O autor observou, em adultos e crianças, dermatites agudas associadas a plantas ou animais em Ubatuba, cidade litorânea de São Paulo, por dois meses (junho/julho de 2006 e na Faculdade de Medicina de Botucatu, também por dois meses (junho/julho de 2007. RESULTADOS: Foram observados 25 pacientes na área rural e 43 na área litorânea nas condições estabelecidas. Em áreas rurais, foram mais observadas fitofotodermatites e picadas de insetos, enquanto em áreas litorâneas traumas por ouriços-do-mar e fitofotodermatites predominaram; entretanto, em ambas as áreas ocorreram outros acidentes de difícil identificação na prática diária. CONCLUSÕES: Devemos estar atentos ao fato de o paciente procurar o dermatologista somente após as fases agudas dos acidentes. Informações sobre as enfermidades mais comuns e suas características podem ser muito úteis para a prática nos consultórios.

    As described by Lori Gruen in the Perspective column at the back of this issue, federally supported biomedical research conducted on chimpanzees has now come to an end in the United States, although the wind-down has taken longer than expected. The process began with a 2011 Institute of Medicine report that set up several stringent criteria that sharply limited biomedical research. The National Institutes of Health accepted the recommendations and formed a committee to determine how best to implement them. The immediate question raised by this transition was whether the IOM restrictions should be extended in some form to other nonhuman primates-and beyond them to other kinds of animals. In the lead article in this issue, Anne Barnhill, Steven Joffe, and Franklin Miller consider the status of other nonhuman primates. PMID:27417859

    Wild boar are widely distributed throughout the Iberian Peninsula and can carry potentially virulent strains of Streptococcus suis. The objective of this study was to determine the prevalence of S. suis in wild boars from two large geographical regions of Spain. Serotypes 1, 2, 7 and 9 identified were further genetically characterised by virulence-associated genotyping, pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) to determine the population structure of S. suis carried by these animals. Streptococcus suis was isolated from 39.1% of the wild boars examined: serotype 9 was the most frequently isolated (12.5%), followed by serotype 1 (2.5%). Serotype 2 was rarely isolated (0.3%). Eighteen additional serotypes were identified indicating wide diversity of this pathogen within the wild boar population. This heterogeneity was confirmed by PFGE and MLST analyses and the majority of isolates exhibited the virulence-associated genotype mrp-/epf-/sly-. The results of this study highlight that the carriage of S. suis by wild boars is commonplace. However, MLST data indicate that these isolates are not related to prevalent clonal complexes ST1, ST16, ST61 and ST87 typically associated with infection of pigs or humans in Europe. PMID:24726078

    2012-04-01

    Full Text Available The radiocaesium activity concentration may still remain high in natural products such as game meat, wild mushrooms, and forest berries even more than two decades after the Chernobyl accident. The results of regular control studies of game meat conducted in Poland showed wild boars as the most contaminated game animals. It is well documented that some mushrooms, readily consumed by animals, show high ability to accumulate caesium radioisotopes. Bay bolete, one of the most wide-spread mushroom species in Poland, reveals a unique radiocaesium accumulation feature. Moreover, deer truffle, containing also particularly high levels of radiocaesium, could be another radionu-clide source for wild boars. Furthermore, animals consuming deer truffles could digest contaminated soil components. Among 94 wild boar meat samples analysed in 2008–2009, two exceeded the permitted level. Hence, some precautions should be taken in the population with an elevated intake of wild boar meat. Moreover, since each hunted wild boar is examined for the presence of Trichinella larvae, regular measurements of radiocaesium concentrations in these animals may be advisable for enhancing consumer safety.

    Artificial selection affects phenotypes differently by natural selection. Domestic traits, which pass into the wild, are usually negatively selected. Yet, exceptionally, this axiom may fail to apply if genes, from the domestic animals, increase fertility in the wild. We studied a rare case of a wild boar population under the framework of Wright's interdemic selection model, which could explain gene flow between wild boar and pig, both considered as demes. We analysed the MC1R gene and microsatellite neutral loci in 62 pregnant wild boars as markers of hybridization, and we correlated nucleotide mutations on MC1R (which are common in domestic breeds) to litter size, as an evaluation of fitness in wild sow. Regardless of body size and phyletic effects, wild boar sows bearing nonsynonymous MC1R mutations produced larger litters. This directly suggests that artificially selected traits reaching wild populations, through interdemic gene flow, could bypass natural selection if and only if they increase the fitness in the wild.

    2010-12-01

    Full Text Available The aim of this study was to investigate the presence of various bacterial species in the wild boar populations of Lugar Nuevo and Selladores-Contadero woodlands from Sierra Morena (Spain. Bacteriological analyses were carried out on a total of 229 wild boar individuals hunted in the period 2000-2003 in eleven experimental plots which are representative for the different biotopes of the area. The following species were detected: Brucella ovis, Clostridium sp., Corynebacterium sp., Streptococcus pneumoniae, Escherichia coli, Mycobacterium bovis, Mycobacterium avium subsp. paratuberculosis, Mannheimia haemolytica, Pasteurella multocida, Pseudomonas aeruginosa, Chlamydophila psittaci, Staphylococcus aureus and Staphylococcus sp. and the bacterial prevalence was estimated for each of them. The results provide useful indications of the health status of wild boar in both locations and highlight the potential of the wild boar populations to act as biological reservoirs of certain microorganisms that can be passed onto other vertebrate wild animals and humans.

  4. Search for Mycobacterium leprae in wild mammals

    Directory of Open Access Journals (Sweden)

    Sílvia Cristina Barboza Pedrini

    2010-02-01

    Full Text Available Leprosy is still a worldwide public health problem. Brazil and India show the highest prevalence rates of the disease. Natural infection of armadillos Dasypus novemcinctus with Mycobacterium leprae has been reported in some regions of the United States. Identification of bacilli is difficult, particularly due to its inability to grow in vitro. The use of molecular tools represents a fast and sensitive alternative method for diagnosis of mycobacteriosis. In the present study, the diagnostic methods used were bacilloscopy, histopathology, microbiology, and PCR using specific primers for M. leprae repetitive sequences. PCR were performed using genomic DNA extracted from 138 samples of liver, spleen, lymph nodes, and skin of 44 D. novemcinctus, Euphractus sexcinctus, Cabassous unicinctus, and C. tatouay armadillos from the Middle Western region of the state of São Paulo and from the experimental station of Embrapa Pantanal, located in Pantanal da Nhecolândia of Mato Grosso do Sul state. Also, the molecular analysis of 19 samples from internal organs of other road killed species of wild animals, such as Nasua nasua (ring-tailed coati, Procyon cancrivoros (hand-skinned, Cerdocyon thous (dog-pity-bush, Cavia aperea (restless cavy, Didelphis albiventris (skunk, Sphigurrus spinosus (hedgehog, and Gallictis vittata (ferret showed PCR negative data. None of the 157 analyzed samples had shown natural mycobacterial infection. Only the armadillo inoculated with material collected from untreated multibacillary leprosy patient presented PCR positive and its genomic sequencing revealed 100% identity with M. leprae. According to these preliminary studies, based on the used methodology, it is possible to conclude that wild mammals seem not to play an important role in the epidemiology of leprosy in the Middle Western region of the São Paulo state and in the Pantanal of Mato Grosso do Sul state.

    In this paper, a new resampling procedure, called the wild tapered block bootstrap, is introduced as a means of calculating standard errors of estimators and constructing confidence regions for parameters based on dependent heterogeneous data. The method consists in tapering each overlapping block......-of-the-art block-based method in terms of asymptotic accuracy of variance estimation and distribution approximation. For stationary time series, the asymptotic validity, and the favorable bias properties of the new bootstrap method are shown in two important cases: smooth functions of means, and M-estimators. The...... estimator for the sample mean is shown to be robust against heteroskedasticity of the wild tapered block bootstrap. This easy to implement alternative bootstrap method works very well even for moderate sample sizes....

  6. Gestural communication in wild chimpanzees

    OpenAIRE

    Hobaiter, Catherine

    2012-01-01

    Great ape gesture is an elaborate, flexible system of intentional communication. It has been suggested that human language originated in gesture, thus, the gestural communication of great apes is of great interest for questions on the origin of language. To date, systematic studies of great ape gesture have been limited to restricted captive settings, supplemented by the study of a few specific gestures in wild populations. To address questions about gestural communication from an evolutionar...

    Full Text Available Interactions that animals experience can have a significant influence on their health and welfare. These interactions can occur between animals themselves, but also between animals and keepers, and animals and the public. Human and non-human animals come into contact with each other in a variety of settings, and wherever there is contact there is the opportunity for interaction to take place. Interaction with companion animals are well known, but human–animal interaction (HAR (Hosey, 2008 also occurs in the context of farms (Hemsworth and Gonyou, 1997; Hemsworth, 2003, laboratories (Chang and Hart, 2002, zoos (Kreger and Mench, 1995 and even the wild (e.g. Cassini, 2001. This project proposes a permanent monitoring scheme to record animal-human interactions and animal-animal interactions in zoos. This will be accompanied by a survey of animal personality for welfare, husbandry, breeding programs and reintroduction purposes. The pilot project is currently based on direct monitoring of animal behaviour, use of time lapse cameras and animal personality questionnaires completed by experienced keepers. The goal of this project is to create a network between zoos to explore the aforementioned interactions to produce husbandry protocols and explore personality and behavioural traits in multiple species. We present provisional data regarding polar bear (Fasano Zoosafari, Italy, Sumatran tigers, Amur tigers and Asiatic lion (ZSL London and Whipsnade zoo interactions with humans and conspecifics. This data is collected across a broad range of environmental conditions and outlines the monitoring protocols developed to collect this data. The first year data show the great adaptability of these species to ex situ environments, low or absent negative impact of visitors’ presence and the relevance of individual personality in these interactions.

    This article reports for the first time data regarding trichinellosis in sacrificed animals (domestic pigs and wild boars) inspected during the period from January 1998 to November 2011 in the largest of the Romanian counties. The data were collected from the Veterinary Public Health Department of Timis County. A total of 5,586,431 domestic pigs on farms, 609,325 pigs in private households, and 823 wild boars were examined during the study period. The results indicated that 681 domestic pigs (0.01%) on farms and 407 pigs in private households (0.07%) were found to be infected with Trichinella. Regarding wild boars, infection was detected in only 4 animals (0.5%). Although no infected animals have recently been identified during routine examinations (2009-2011), human outbreaks continue to occur yearly, and the main factors for these include improper handling by the population.

  11. Wild chimpanzees show population-level handedness for tool use.

    Lonsdorf, Elizabeth V; Hopkins, William D

    2005-08-30

    Whether nonhuman primates exhibit population-level handedness remains a topic of considerable theoretical and empirical debate. One continued subject of discussion is whether evidence of population-level handedness in primates is confined to studies in captive animals or whether it is in both captive and wild subjects. Here, we report evidence of population-level handedness in wild chimpanzees for a tool-use task known as "termite-fishing." We subsequently compared the handedness for termite-fishing with other published reports on handedness for nut-cracking and wadge-dipping and found task-specific differences in handedness. Last, when combing all of the published data on tool use in wild chimpanzees, we show that hand preferences are heritable. Contrary to previous claims, our results demonstrate that population-level handedness is evident in wild chimpanzees and suggest that the antecedents of lateralization of function associated with hand use were present at least 5 million years ago, before the Pan-Homo split.

  12. Cytogenetic radio-sensitivity in wild and laboratory rats

    International Nuclear Information System (INIS)

    Radiation-induced chromosomal aberrations have been found differ considerably between different species and also between individuals of the same species (Andrews, 1958; Carlson, 1954; Scott and Bigger, 1974). The work of Blumel (1950) on drosophila and crowley and curtis (1963) on mice represent few examples of the vast differences in frequencies of radiation-induced chromosomal aberrations in different species. however, in most cases, all experimental work on the genetic effects of radiation has been carried out on laboratory stocks that have been living under artificial conditions. Domestication of many organisms has been found to be associated with many genetical changes (Berry, 1969). Searle, berry and Beechey (1970) have reported significant differences between irradiated wild and laboratory mice in the frequency of translocations in spermatocyte ,metaphases. Badr and Badr (1971 a, b) have found that the responses of two different populations of rats, a laboratory albino strain (Rattus norvegicus) and a wild type (Rattus Rattus) to various doses of X-ray irradiation in terms of mitotic activity, mortality rate and mean survival times are significantly different. In this report, the differential response of two populations of the rat (Rattus norvegicus), wild and laboratory types, to X-ray irradiation in bone marrow cells has been studied. These comparative studies are needed to supplement the now available information on the response of the wild form of experimental animals and thereby to provide a better understanding of the magnitude of radiosensitivities within a species. 4 tabs., 1 tab

  13. Cross-modal individual recognition in wild African lions.

    2016-08-01

    Individual recognition is considered to have been fundamental in the evolution of complex social systems and is thought to be a widespread ability throughout the animal kingdom. Although robust evidence for individual recognition remains limited, recent experimental paradigms that examine cross-modal processing have demonstrated individual recognition in a range of captive non-human animals. It is now highly relevant to test whether cross-modal individual recognition exists within wild populations and thus examine how it is employed during natural social interactions. We address this question by testing audio-visual cross-modal individual recognition in wild African lions (Panthera leo) using an expectancy-violation paradigm. When presented with a scenario where the playback of a loud-call (roaring) broadcast from behind a visual block is incongruent with the conspecific previously seen there, subjects responded more strongly than during the congruent scenario where the call and individual matched. These findings suggest that lions are capable of audio-visual cross-modal individual recognition and provide a useful method for studying this ability in wild populations. PMID:27555649

  15. Molecular epidemiology of Mycoplasma hyopneumoniae from outbreaks of enzootic pneumonia in domestic pig and the role of wild boar.

    Kuhnert, Peter; Overesch, Gudrun

    2014-11-01

    Mycoplasma hyopneumoniae is the major cause of enzootic pneumonia (EP) in domestic pigs, a disease with low mortality but high morbidity, having a great economic impact for producers. In Switzerland EP has been successfully eradicated, however, sporadic outbreaks are observed with no obvious source. Besides the possibility of recurrent outbreaks due to persisting M. hyopneumoniae strains within the pig population, there is suspicion that wild boars might introduce M. hyopneumoniae into swine herds. To elucidate possible links between domestic pig and wild boar, epidemiological investigations of recent EP outbreaks were initiated and lung samples of pig and wild boar were tested for the presence of specific genotypes by multilocus sequence typing (MLST). Despite generally different genotypes in wild boar, outbreak strains could be found in geographically linked wild boar lungs after, but so far not before the outbreak. Recurrent outbreaks in a farm were due to the same strain, indicating unsuccessful sanitation rather than reintroduction by wild boar. In another case outbreaks in six different farms were caused by the same strain never found in wild boar, confirming spread between farms due to hypothesized animal transport. Results indicate the presence of identical lineages of wild boar and domestic pig strains, and possible transmission of M. hyopneumoniae between wild boar and pig. However, the role of wild boar might be rather one as a recipient than a transmitter. More important than contact to wild boar for sporadic outbreaks in Switzerland is apparently persistence of M. hyopneumoniae within a farm as well as transmission between farms. PMID:25236987

    Full Text Available We analyzed signs occurring among domestic and wild terrestrial animal species infected with raccoon rabies variant virus (RRV in Massachusetts, 1992–2010. The clinical sign of aggression was significantly associated with rabid stray cats (odds ratio, OR = 2.3 and RRV affected major wild terrestrial animal species individually, which included raccoons (OR = 2.8, skunks (OR = 8.0, gray foxes (OR = 21.3, red foxes (OR = 10.4, woodchucks (OR = 4.7 and coyotes (OR = 27.6. While aggression is a useful predictor of rabies among wild animals, combinations of other signs such as ataxia, disorientation, and salivation are useful predictors of rabies among domestic animals. Pets reported with multiple clinical signs had significantly higher rabies positive testing result than those reported with single clinical sign (p < 0.001. The result suggested the importance of avoiding aggressive terrestrial wild animals and giving additional attention to pets with multiple clinical signs.

    Laboratory animal is the animal with artificial feeding in the certain conditions, having the particular biological characteristics and for scientific research. They are indispensable props of life science and have made great contributions and sacrifices for human health and development. Laboratory animal science is an important branch of the life science,including laboratory animal and animal experiment. Along with development of mankind society, economy and civilization, now the realm of laboratory animal science is confronted with the problems of animal welfare and animal ethics.The animal protectionism inevitably conflict with the laboratory animal science in the certain way. People protect the wild animals first, then protect the artificially fed animal. Also people protect pets first and then protect the laboratory animals. Now it is popularization of protecting the wild and petted animals. It makes people hard to accept the reality of the experiments with animals. But life science especially biomedicine can't make great progress without the laboratory animals.

    Do non‐human animals have rights? The answer to this question depends on whether animals have morally relevant mental properties. Mindreading is the human activity of ascribing mental states to other organisms. Current knowledge about the evolution and cognitive structure of mindreading indicates that human ascriptions of mental states to non‐human animals are very inaccurate. The accuracy of human mindreading can be improved with the help of scientific studies of animal minds. However, the s...

    The role of domestic dogs in the epidemiology of Neospora caninum as well as the relationship between N. caninum infection of farm dogs and cattle were demonstrated, however, evidence is scarce regarding the role of wild canids in domestic animal neosporosis. The present study was undertaken to evaluate the role of wild canids in the epidemiology of bovine neosporosis in Israel by analyzing the prevalence of antibodies to N. caninum in wild canids. Sera samples were collected from 114 free ranging wild golden jackals (Canis aureus), 24 red foxes (Vulpes vulpes) and nine wolves (Canis lupus), which were collected in Israel during the years 1999-2004. Of a total of 147 wild canids tested antibodies to N. caninum were only found in two golden jackals with IFAT titers of 1:50, and in one red fox and one wolf with IFAT titer of 1:400. The low seroprevalence found in this study (2.7%) indicated that wild canids probably do not have an important role in the epidemiology of N. caninum in Israel. However, since the diet of different species of wild canids and even diverse populations of the same canid species vary, it is possible that other results might be obtained from specific wild canids populations, which scavenge in the vicinity of infected bovines.

    2016-01-01

    Anthropogenic noise has been increasing globally. Laboratory experiments suggest that noise disrupts foraging behavior across a range of species, but to reveal the full impacts of noise, we must examine the impacts of noise on foraging behavior among species in the wild. Owls are widespread nocturnal top predators and use prey rustling sounds for localizing prey when hunting. We conducted field experiments to examine the effect of traffic noise on owls’ ability to detect prey. Results suggest that foraging efficiency declines with increasing traffic noise levels due to acoustic masking and/or distraction and aversion to traffic noise. Moreover, we estimate that effects of traffic noise on owls’ ability to detect prey reach >120 m from a road, which is larger than the distance estimated from captive studies with bats. Our study provides the first evidence that noise reduces foraging efficiency in wild animals, and highlights the possible pervasive impacts of noise. PMID:27537709

    Infestation with Sarcoptes scabiei was diagnosed from four wild raccoon dogs (Nyctereutes procyonoides) accidentally captured and presented to the Animal Health Center in Seoul Grand Park Zoo, Korea. Diagnosis was done by microscopic and histologic examination from skin lesions. Sarcoptes scabiei was the only species detected from the lesions and characterized by dorsoventrally flattened and round bodies, sucker-like pulvilli borne on long nonjointed pretarsi, triangular scales and spinelike setae on the dorsum, and three epimeres that are chitinous extensions of the coxae of the legs. In addition, infiltration of mast cells in the dermis was associated with infestation of the burrowing mite. This is the first report of sarcoptic mange in raccoon dogs in Korea. Because heavy infestation with S. scabiei was found in all of the captured wild raccoon dogs, further work is necessary to develop prophylactic interventions to prevent the spread of sarcoptic mange in free-living raccoon dogs in Korea.

    Hundreds of thousands of laboratory animals are being used every year for scientific experiments held in Israel, mostly mice, rats, rabbits, guinea pigs, and a few sheep, cattle, pigs, cats, dogs, and even a few dozen monkeys. In addition to the animals sacrificed to promote scientific research, millions of animals slain every year for other purposes such as meat and fine leather fashion industries. While opening a front against all is an impossible and perhaps an unjustified task, the state of Israel enacted the Animal Welfare (Animal Experimentation) Law (1994). The law aims to regulate scientific animal experiments and to find the appropriate balance between the need to continue to perform animal experiments for the advancement of research and medicine, and at the same time to avoid unnecessary trials and minimize animal suffering. Among other issues the law deals with the phylogenetic scale according to which experimental animals should be selected, experiments for teaching and practicing, and experiments for the cosmetic industry. This article discusses bioethics considerations in animal experiments as well as the criticism on the scientific validity of such experiments. It further deals with the vitality of animal studies and the moral and legal obligation to prevent suffering from laboratory animals. PMID:24660572

    Wild fire vulnerability is a measure of potential socio-economic damage caused by a fire in a specific area. As such it is an important component of long-term fire risk management, helping policy-makers take informed decisions about adequate expenditures for fire prevention and suppression, and to target those regions at highest risk. This paper presents a first approach to assess wild fire vulnerability at the European level. A conservative approach was chosen that assesses the cost of restoring the previous land cover after a potential fire. Based on the CORINE Land Cover, a restoration cost was established for each land cover class at country level, and an average restoration time was assigned according to the recovery capacity of the land cover. The damage caused by fire was then assessed by discounting the cost of restoring the previous land cover over the restoration period. Three different vulnerability scenarios were considered assuming low, medium and high fire severity causing different levels of damage. Over Europe, the potential damage of wild land fires ranges from 10 - 13, 732 Euro*ha-1*yr-1 for low fire severity, 32 - 45,772 Euro*ha-1*yr-1 for medium fire severity and 54 - 77,812 Euro*ha-1*yr-1 for high fire severity. The least vulnerable are natural grasslands, moors and heathland and sclerophyllous vegetation, while the highest cost occurs for restoring broad-leaved forest. Preliminary validation comparing these estimates with official damage assessments for past fires shows reasonable results. The restoration cost approach allows for a straightforward, data extensive assessment of fire vulnerability at European level. A disadvantage is the inherent simplification of the evaluation procedure with the underestimation of non-markets goods and services. Thus, a second approach has been developed, valuing individual wild land goods and services and assessing their annual flow which is lost for a certain period of time in case of a fire event.

    Full Text Available A Wireless Nano Sensor Network (WNSN is a collection of Nano Sensor nodes that dynamically self organize them in a wireless network without a need but with possible utilization of any pre-existing infrastructure. WNSNs may be employed on the wildlife health and condition monitoring. Most of the current research in WNSNs on wildlife monitoring is performed on theoretical basis involving simulations of abstract, unrealistic situations. The research focusing on the real life evaluation of the WNSN techniques involves usually nano-scale studies with the very limited number of nodes attached with the body of the wild animals. The major problem with the Sensors/ Radio Collar which are attachedto the body of wild animals is size of the mote. For which reasons they feel uncomfortable and when they try to be free from it, the mechanism would be damaged. Then it is needed to be changed and it affects the cost. And for the macro size of the Sensors/ Radio Collar, the power consumption is also high which isthe main problem is for the maintainer. It requires changing the battery frequently. Finding the location of that certain animal and putting it into a cage after tranquilization claimed a huge amount time andlabour.

    Full Text Available The aim of this research is to characterise the wild rabbit (Oryctolagus cuniculus commercial game farms in Spain using variables related to structure, management and marketing. To this end, a structured survey was administered in 2009 to 21 privately-owned farms. This subsector was an average age of 13. The average size of the breeding stock of the farms was 431 does and 64 bucks. Eighty-five percent of the farms kept all or part of the breeding stock in cages and 38.1% used artificial insemination. All the farms carried out breeder self-replacement, 4.8% by buying wild rabbits from other farms, whereas 38.1% captured wild rabbits for this purpose. Nineteen percent of the wild rabbit game farms also produced other game species, mainly red-legged partridge (Alectoris rufa, pheasant (Phasianus colchicus and quail (Coturnix coturnix. Fourteen percent of the farms supplied wild rabbits to be used as prey to be released in programmes for the conservation of endangered predators, and 38.1% supplied breeding rabbits to be used by other farms to replace culled animals. Eighty-six percent of the farms offered the service of transporting the animals from the farm to the hunting grounds to their clients, and 14.3% advised customers on how to successfully release and restock hunting grounds. Seventy-six percent of the farms marketed their products throughout Spain, and 38.1% exported wild rabbits to neighbouring countries, mainly Portugal and France. Forty-three percent of the farms advertised themselves in hunting magazines, 19.1% promoted themselves by attending livestock and game fairs, and 38.1% had their own websites. In conclusion, this alternative rabbit production system constitutes a well-established subsector in Spain, despite being only 2 decades old. It also seems that it has not yet reached its development maturity. It shows wide diversity in terms of farm size and structure, as well as marketing and promotional activities.

    Bruin, Henk

    2012-01-01

    Fibonacci unimodal maps can have a wild Cantor attractor, and hence be Lebesgue dissipative, depending on the order of the critical point. We present a one-parameter family $f_\\lambda$ of countably piecewise linear unimodal Fibonacci maps in order to study the thermodynamic formalism of dynamics where dissipativity of Lebesgue (and conformal) measure is responsible for phase transitions. We show that for the potential $\\phi_t = -t\\log|f'_\\lambda|$, there is a unique phase transition at some $t_1 \\le 1$, and the pressure $P(\\phi_t)$ is analytic (with unique equilibrium state) elsewhere. The pressure is majorised by a non-analytic $C^\\infty$ curve (with all derivatives equal to 0 at $t_1 < 1$) at the emergence of a wild attractor, whereas the phase transition at $t_1 = 1$ can be of any finite order for those $\\lambda$ for which $f_\\lambda$ is Lebesgue conservative. We also obtain results on the existence of conformal measures and equilibrium states, as well as the hyperbolic dimension and the dimension of th...

  17. Echolocation signals of wild dolphins

    Au, W. W. L.

    2004-07-01

    Most of our understanding of dolphin echolocation has come from studies of captive dolphins performing various echolocation tasks. Recently, measurements of echolocation signals in the wild have expanded our understanding of the characteristics of these signals in a natural setting. Measuring undistorted dolphin echolocation signals with free swimming dolphins in the field can be a challenging task. A four hydrophone array arranged in a symmetrical star pattern was used to measure the echolocation signals of four species of dolphins in the wild. Echolocation signals of the following dolphins have been measured with the symmetrical star array: white-beaked dolphins in Iceland, Atlantic spotted dolphins in the Bahamas, killer whales in British Columbia, and dusky dolphins in New Zealand. There are many common features in the echolocation signals of the different species. Most of the signals had spectra that were bimodal: two peaks, one at low frequencies and another about an octave higher in frequency. The source level of the sonar transmission varies as a function of 20log R, suggesting a form of time-varying gain but on the transmitting end of the sonar process rather than the receiving end. The results of the field work call into question the issue of whether the signals used by captive dolphins may be shaped by the task they are required to perform rather than what they would do more naturally.

    Full Text Available Two species of wild potato Solanum commersonii, subspecies commersonii and malmeanum, and S. chacoense, subspecies muelleri occur in southern Brazil. Their rusticity and easy adaptation to extreme climatic conditions make them valuable for breeding programs. The objective of this work was to analyze the isoenzymatic variability of 113 clones of wild potato subspecies. They were collected and maintained at Embrapa-Centro de Pesquisa Agropecuária de Clima Temperado, at Pelotas, RS, Brazil. Enzymes involved in energetic (group I or in peripherical (group II metabolism constituted the material used. Polyacrylamide horizontal gel electrophoresis was used to analyze peroxidase, aspartate transaminase, phosphoglucomutase and isocitrate dehydrogenase isoenzymes. Solanum spp. has considerable genetic variability for isoenzymatic patterns. Cluster analysis classified the clones into 51 subgroups, based on electrophoretic variants of group I enzymes, and into 89, when group II enzyme variants were added. Genotypic differentiation of S. chacoense muelleri in relation to S. commersonii commersonii and S. commersonii malmeanum is evident when expressed through similarity and cluster analysis.

    The results presented describe and compare the fatty acid composition and melting properties of captive, healthy wild, and pansteatitis-affected wild crocodiles (Crocodylus niloticus). Differences in fatty acid composition between intramuscular and adipose fat is noted in captive crocodiles, and the latter differs from wild crocodiles as a result of different diets. Adipose fat of healthy wild crocodiles differs minimally from diseased ones, respectively with 37.3+/-2.6% vs. 43.2+/-2.3% monounsaturated fatty acids, and 43.2+/-2.9% in dead crocodiles, while polyunsaturated fatty acids decrease from 27.3+/-1.9% to as low as 21.9+/-3.6% respectively. Of the unsaturated fatty acids 18:2n-6 decreased from 6.5+/-2.6% in unaffected crocodiles to 3.5+/-0.6% in highly affected and 3.2+/-0.4% in dead crocodiles, and 22:5n-3 from 2.8+/-0.6% to 1.8+/-0.3% and 2.2+/-0.3% respectively. The melting properties as determined by differential scanning calorimetry show that extracted adipose fat is a small degree softer in pansteatitis-affected tissue, specifically in the temperature range 7-36 degrees C, and does not contribute to the hard texture noted for adipose fat tissue of pansteatitis-affected animals. A high moisture content of 51.0+/-19.7% of the fat tissue of pansteatitis-affected animals vs.17.1+/-8.0% of healthy ones, suggests that physiological changes due to interstitial inflammation may contribute to the hard texture.

    Full Text Available Anthropogenic pressure causes significant changes in the environment that affect the fauna. However, few studies have been conducted to support management and handling of wild animals victimized in urban ecosystem. The purpose of this study was to evaluate the decentralized management of wildlife by the Municipality of São Paulo, through the Technical Division of Veterinary Medicine and Wild Fauna Management (DEPAVE-3, of Municipal Secretariat for Environment. The methodology was based on references and data obtained from the care of animals that passed through the service in the period 1993 to 2007. The research showed that the DEPAVE-3 is structured to make the veterinary medical and biological support for wild animals, seeking their replacement in nature. The study evaluated and described the physical structure the physical structure and operational assignments related to the handling of animals, the investigation of zoonoses, the inventory of fauna, in addition to data used in decision making. In conclusion, the study showed that the successful management of wildlife, held by the Municipality of São Paulo, stems from the existence of a service aimed at serving victimized animals in the region and recommends that this model be also implemented in other major urban centers.

    What does domestication select for in terms of foraging and anti-predator behaviors? We applied principles of patch use and foraging theory to test foraging strategies and fear responses of three strains of Mus musculus: wild-caught, control laboratory, and genetically modified strains. Foraging choices were quantified using giving-up densities (GUDs) under three foraging scenarios: (1) patches varying in microhabitat (covered versus open), and initial resource density (low versus high); (2) daily variation in auditory cues (aerial predators and control calls); (3) patches with varying seed aggregations. Overall, both domestic strains harvested significantly more food than wild mice. Each strain revealed a significant preference for foraging under cover compared to the open, and predator calls had no detectable effects on foraging. Both domestic strains biased their harvest toward high quality patches; wild mice did not. In terms of exploiting favorable and avoiding unfavorable distributions of seeds within patches, the lab strain performed best, the wild strain worst, and the mutant strain in between. Our study provides support for hypothesis that domestic animals have more energy-efficient foraging strategies than their wild counterparts, but retain residual fear responses. Furthermore, patch-use studies can reveal the aptitudes and priorities of both domestic and wild animals. PMID:26548716

    Helicobacter species are widely distributed in the gastrointestinal system of humans and many animal taxa. Investigations of natural infections are essential to elucidating their role within the host. The feces of fur seals Arctocephalus pusillus doriferus and sea lions Neophoca cinerea from 3 separate captive populations, as well as a wild colony from Kangaroo Island, Australia, were examined for the occurrence of Helicobacter spp. The feces from several wild silver gulls Larus novahollandiae were also investigated. As detected by PCR, 18 of 21 samples from captive and 12 of 16 samples from wild seals were positive for Helicobacter spp. Three species were identified in these animals. Whilst one possibly novel type was identified from wild fur seals, the majority of wild and captive individuals had the same species. This species also occurred in more than 1 seal type and in silver gulls, and shared a 98.1 to 100% identity to other Helicobacter spp. from harp seals and sea otters. A similar sequence type to species identified from cetaceans was also detected in several captive seals. This study reports for the first time the presence of Helicobacter spp. in wild and captive seals and demonstrates the diversity and broad-host range of these organisms in the marine host.

    This article discusses the notion that the invisibility of the animalness of the animal constitutes a fundamental obstacle to change within current production systems. It is discussed whether housing animals in environments that resemble natural habitats could lead to a re-animalization...... of the animals, a higher appreciation of their moral significance, and thereby higher standards of animal welfare. The basic claim is that experiencing the animals in their evolutionary and environmental context would make it harder to objectify animals as mere bioreactors and production systems. It is argued...... that the historic objectification of animals within intensive animal production can only be reversed if animals are given the chance to express themselves as they are and not as we see them through the tunnel visions of economy and quantifiable welfare assessment parameters....

    Nature-based tourism can generate important revenue to support conservation of biodiversity. However, constant exposure to tourists and subsequent chronic activation of stress responses can produce pathological effects, including impaired cognition, growth, reproduction, and immunity in the same animals we are interested in protecting. Utilizing fecal samples (N = 53) from 2 wild habituated orangutans (Pongo pygmaeus morio) (in addition to 26 fecal samples from 4 wild unhabituated orangutans) in the Lower Kinabatangan Wildlife Sanctuary of Sabah, Malaysian Borneo, we predicted that i) fecal glucocorticoid metabolite concentrations would be elevated on the day after tourist visitation (indicative of normal stress response to exposure to tourists on the previous day) compared to samples taken before or during tourist visitation in wild, habituated orangutans, and ii) that samples collected from habituated animals would have lower fecal glucocorticoid metabolites than unhabituated animals not used for tourism. Among the habituated animals used for tourism, fecal glucocorticoid metabolite levels were significantly elevated in samples collected the day after tourist visitation (indicative of elevated cortisol production on the previous day during tourist visitation). Fecal glucocorticoid metabolite levels were also lower in the habituated animals compared to their age-matched unhabituated counterparts. We conclude that the habituated animals used for this singular ecotourism project are not chronically stressed, unlike other species/populations with documented permanent alterations in stress responses. Animal temperament, species, the presence of coping/escape mechanisms, social confounders, and variation in amount of tourism may explain differences among previous experiments. Acute alterations in glucocorticoid measures in wildlife exposed to tourism must be interpreted conservatively. While permanently altered stress responses can be detrimental, preliminary results

    The use of animals in research will be necessary for scientific advances in the basic and biomedical sciences for the foreseeable future.As we learn more about the ability of animals to experience pain,suffering,and distress,and particularly for mammals,it becomes the responsibility of scientists,institutions,animal caregivers,and veterinarians to seek ways to improve the lives of research animals and refine their care and use.Refinement is one of the three R's emphasized by Russell and Burch,and refers to modification of procedures to minimise the potential for pain,suffering and distress. It may also refer to procedures used to enhance animal comfort. This paper summarizes considerations for refinements in research animal.

    Field studies of four sympatric parrot species in Costa Rica are revealing several possible functions for the well-known ability of parrots to mimic new sounds throughout life. Despite earlier suggestions that this might facilitate exchanges of environmental information, all data so far suggest that vocal mimicry in the wild is associated with mediation of the fission/fusion of groups of parrots and/or of conflicts between mated pairs. Recent results using array recording and interactive playback will be summarized, and several technical problems created by the mechanisms of parrot vocal signal production discussed.

    2013-04-01

    We sampled 325 small and medium-sized wild mammals in Ontario, Canada in 2007 and 2010 to determine the prevalence and characteristics of Clostridium difficile in wild mammals living in proximity to captive wildlife and livestock. Clostridium difficile was isolated from five of 109 animals (4.6%) on four of 25 farms (16%), but was not isolated from any of the 216 samples from raccoons (Procyon lotor) living on the grounds of the Toronto Zoo. The positive animals included two raccoons from one beef farm, one raccoon from a different beef farm, one raccoon from a swine farm, and a shrew (Blarina brevicauda) from a dairy farm. None had evidence of gastrointestinal disease. Three of the five isolates were toxinotype variants (II, IV, and XIII) that are rarely identified in humans and domestic animals. The other two were toxinotype 0, a common toxinotype in humans and animals; however, all five isolates were of different ribotypes. None of the recovered ribotypes were recognized as ribotypes present in the authors' reference library of over 3,000 human and domestic animal C. difficile isolates. Neither the public health nor the animal health relevance of these findings is clear. It is not known whether C. difficile is a pathogen of small and medium-sized wild mammals, although the susceptibility of various laboratory species suggests it could cause disease. PMID:23568920

    For years, the animal culture debate has been dominated by the puzzling absence of direct evidence for social transmission of behavioral innovations in the flagship species of animal culture, the common chimpanzee. Although social learning of novel behaviors has been documented in captivity, critics argue that these findings lack ecological validity and therefore may not be relevant for understanding the evolution of culture. For the wild, it is possible that group-specific behavioral differences emerge because group members respond individually to unspecified environmental differences, rather than learning from each other. In a recent paper, we used social network analyses in wild chimpanzees (Pan troglodytes schweinfurthii) to provide direct evidence for social transmission of a behavioral innovation, moss-sponging, to extract water from a tree hole. Here, we discuss the implications of our findings and how our new methodological approach could help future studies of social learning and culture in wild apes. PMID:26479151

In total, 22 (50% wild boars were PCR positive. Sequencing of the amplicons identified Chlamydia suis and Chlamydia pecorum in 12 and 5 samples, respectively. For one sample found PCR positive, the nucleotide sequence could not be determined. Four conjunctival samples showed ≥ 92% sequence similarities to 16S rRNA sequences from Chlamydia-like organisms, as did large intestine, uterus, and vaginal swabs from the same four animals. Amoeba DNA was found in one Chlamydia-like organism positive conjunctival swab. To our knowledge, this is the first detection of members of the Parachlamydiaceae family in wild boars, confirming a large animal host range for Chlamydia-like organisms.

    Full Text Available We reviewed historical records of the abundance and distribution of wild reindeer {Rangifer tarandus L. in Chukotka and studied reindeer numbers, distribution and behavior from 1983 to 1993. There were large numbers of wild reindeer in Chukotka until the end of the eighteenth century, but during the nineteenth century the population declined probably from intensive harvest after the introduction of firearms by the Cossacks. During the nineteenth century herding of domestic reindeer also increased, and reindeer herders continued to hunt wild reindeer intensively. During the 1950s there were only about 8500 wild reindeer in two separate herds in Chukotka. By the late 1970s the wild reindeer population had increased to about 11 000. Ten years later we estimated 16 534 reindeer, and found only one contiguous population. Presently, the population calves and spends the summer in the Anadyr Uplands and migrates west and southwest to spend the winter in forest tundra and northern taiga regions. Predators, primarily wolves and brown bears, kill a significant number of calves. Today, the wild reindeer in Chukotka coexist with 300 000 domestic reindeer. However, current costs of gasoline and helicopters make it prohibitive to herd reindeer in much of central Chukotka, so that wild reindeer have room for expansion. Poaching is a major conservation problem. Poachers shoot wild reindeer from helicopters to obtain velvet antlers. Leaders of domestic reindeer cooperatives encourage poaching by telling people that wild reindeer are in fact just stray domestic reindeer and there is no enforcement of game laws.

    Full Text Available Marine animals contain various carotenoids that show structural diversity. These marine animals accumulate carotenoids from foods such as algae and other animals and modify them through metabolic reactions. Many of the carotenoids present in marine animals are metabolites of β-carotene, fucoxanthin, peridinin, diatoxanthin, alloxanthin, and astaxanthin, etc. Carotenoids found in these animals provide the food chain as well as metabolic pathways. In the present review, I will describe marine animal carotenoids from natural product chemistry, metabolism, food chain, and chemosystematic viewpoints, and also describe new structural carotenoids isolated from marine animals over the last decade.

    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.

    An investigation into the potential for transmission of gastrointestinal helminths from wild hogs to livestock and humans was prompted by concerns of recreational wild-hog hunting in the Caribbean region and the recent practice, by livestock farmers in Jamaica, of co-rearing wild and domesticated swine. Thirty-one wild hogs from the Hellshire Hills, a dry limestone forest in southern Jamaica, were necropsied during the period June 2004 to August 2006. Thirteen of the captured animals were male and 18 female. Four species of adult helminths were recovered from the gastrointestinal tracts of the wild hogs: Hyostrongylus rubidus (77%), Globocephalus urosubulatus (48%), Oesophagostomum dentatum (42%) and Macroacanthorhynchus hirudinaceus (77%). Two (6.2%), ten (32.2%) and 18 (58.0%) hogs harboured one, two and three species of helminths, respectively. Mean infection intensities varied from 8.1 for M. hirudinaceus, to 115.5 for O. dentatum. There was no association between any of the recovered helminths and sex of the host; however, a multivariate analysis indicated a positive association between the prevalence of G. urosubulatus and host age (odds ratio (OR) = 6.517). Domesticated hogs co-reared with wild hogs are potentially at risk of infection with all four helminths, while wild-hog hunters and pig farmers may be exposed to M. hirudinaceus. PMID:26821705

    1986-06-01

    Release of Hg compounds into the environment from point sources has largely been curtailed due to the known impacts of Hg on biological systems. Mercury continues to be released into the environment, however, from nonpoint sources such as combustion of fossil fuels and smelting operations. While the accumulation and toxicity of Hg in aquatic biota, domestic animals, and humans is well documented, relatively little is understood about these processes in wild terrestrial mammals. The purpose of this paper is to review the available literature on Hg levels and toxicity in wild mammals (excluding marine mammals). It is clear that Hg levels are biomagnified within terrestrial food chains, where carnivores greater than omnivores greater than herbivores. Among carnivorous species, Hg levels are generally highest in fish-eating animals. There is usually a high degree of correlation of Hg levels between different animal tissues. The age and sex of an animal appear to influence observed Hg levels, but field data are conflicting for both factors. Tissue Hg levels are affected by location, with significant differences attributable to both local contamination and natural background variability. Experimental studies have shown many mammal species to sensitive to Hg intoxication, but documented incidents of Hg poisoning in wild mammals are rare. Such rarity may be more a function of our inability to observe and demonstrate Hg poisoning in wild populations, rather than an absence of the disease. PMID:3519207

    Streptococcus mutans, an organism implicated in dental caries and not previously found outside of man and certain laboratory animals, was isolated from the mouths of wild rats which ate sugar cane. The strains isolated fermented mannitol and sorbitol, and failed to grow in 6.5% NaCl or at 45 C. They formed in vitro plaques on nichrome wires when grown in sucrose broth. They also stored intracellular polysaccharide which could be catabolized by washed, resting cells. Deoxyribonucleic acid-deoxyribonucleic acid reassociations revealed two genetic types. One type shared extensive deoxyribonucleic acid base sequences with S. mutans strains HS6 and OMZ61, two members of a genetic type found in man and laboratory hamsters. The other type seemed unrelated to any S. mutans genetic type previously encountered. It is concluded that the ecological triad of tooth-sucrose-S. mutans is not a phenomenon unique to man and experimental animals. PMID:4601769

    2008-01-01

    Since Roman Antiquity, domestic and wild animals have been transported over long distances for purposes as different as improvement of livestock production, food supply, scientific interest, public entertainment, war and numerous other purposes. This long distance transportation was originally limited to the Mediterranean area but, during the Middle Ages extended to the rest of Europe. The conquest of the New World was the first major occasion to transport large numbers of horses and other livestock across the oceans. Domestic animals were necessary for the new colonies and their armies. European expansion to Asia and the Pacific also required the transportation of large numbers of domestic animals. Data, figures and description of the conditions of transport of animals as different as wild beasts, horses, camels, elephants or poultry are reported for each historical period. PMID:20405409

    Aquatic and migratory birds, the main reservoir hosts of avian influenza viruses including those with high pathogenic potential, are the wildlife species with the highest risk for viral dissemination across countries and continents. In 2002, the Chilean poultry industry was affected with a highly pathogenic avian influenza strain, which created economic loss and triggered the establishment of a surveillance program in wild birds. This effort consisted of periodic samplings of sick or suspicious animals found along the coast and analyses with standardized techniques for detection of influenza A virus. The aim of this work is to report the detection of three avian influenza strains (H13N2, H5N9, H13N9) in gulls from Chile between 2007-2009, which nucleotide sequences showed highest similitudes to viruses detected in wild birds from North America. These results suggest a dissemination route for influenza viruses along the coasts of Americas. Migratory and synanthropic behaviors of birds included in this study support continued monitoring of avian influenza viruses isolated from wild birds in The Americas and the establishment of biosecurity practices in farms.

    2011-01-01

    In hand reared birds and mammals,it is generally considered that the development of hoarding behavior is the result of an interaction between the development and maturation of the nervous system and learning from individual experience.However,few studies have been done on wild animals.We tested differences in hoarding behavior between captive reared and wild individuals of two sympatric small rodents,Korean field mice Apodemus peninsulae and Chinese white-bellied rats Niviventer confucianus.Our aim was to identify if lack of experience from the wild would result in poorly developed hoarding behavior.The Korean field mice perform scatter- and larder-hoarding behaviors whereas Chinese white-bellied rats hoard food in larders only.Within outdoor enclosures we compared seed-hoarding behavior in reared juveniles (RJ,40-50 d old,pregnant mothers were captured in the wild),wild juveniles (WJ,as young as the R J) and wild adults (WA,over-winter animals).We found that a lack of experience from the wild had significant effects on seed-hoarding behavior for both species.The R J-group removed and hoarded fewer seeds than the WJ- and WA-groups.The two latter groups hoarded seeds in a similar way.In the Korean filed mouse the RJ-group placed more seeds on the ground surface than other groups.These findings suggest that wild experience is important for the acquisition of an appropriate food-hoarding behavior (especially for scatter-hoarding) in these species [Current Zoology 57 (6):725-730,2011].

  15. Animal Images and Metaphors in Animal Farm

    Directory of Open Access Journals (Sweden)

    Ping Sun

    2015-05-01

    Full Text Available In literary works animal images are frequently used as the “source domain” of a metaphor to disclose the natures of the “target domain”, human beings. This is called “cross-domain mapping” or “conceptual metaphor” in cognitive linguistics, which is based on the similar qualities between animals and human beings. Thus the apparent descriptions of the animals are really the deep revelations of the human beings. Animal Farm is one exemplary product of this special expressing way. Diversified animal images are intelligently used by George Orwell to represent the people, so all the characters are animals in appearance, but humans in nature. Starting from the animal images and then the conceptual metaphors, readers can perceive a fresh understanding of this classical book. In this novel, three conceptual metaphors are identified and the special findings can be illustrated as the following: Firstly, the whole story of the animals represents the history and politics of the Soviet Union. Secondly, the pigs symbolize the authorities of the society. Thirdly, the names of the characters in the novel reveal their identities.

  16. Trichinella spp. imported with live animals and meat.

    2015-09-30

    Nematodes of the genus Trichinella are widely distributed throughout the world in omnivorous and carnivorous animals (mammals, birds, and reptiles) and in incidental hosts. To prevent the transmission of these zoonotic parasites to humans, meat samples from Trichinella spp. susceptible animals are tested at the slaughterhouse or in game processing plants. The aim of the present review was to collect documented cases on Trichinella infected animals, meat, or meat derived products which reached the international trade or were illegally introduced from one to another country in personal baggage. In the course of the last 60 years in the international literature, there have been 43 reports of importation of Trichinella spp. infected animals or meat, most of which (60%, 26/43) related to live horses or their meat. Meat or meat derived products from pigs, wild boar and bears, account only for 18.6% (8/43), 4.7% (3/43), and 14.3% (6/43), respectively. However, only live horses or their meat intended for human consumption, meat from a single wild boar, and live polar bears caught in the wild for zoos, were imported through the international market; whereas, meat from pigs, wild boars and bears were illegally introduced in a country in personal baggage. Trichinella infected animals or meat which were officially or illegally introduced in a country were the source of 3443 Trichinella infections in humans in a 40-year period (1975-2014). Most of these infections (96.8%) have been linked to horsemeat consumption, whereas meat from pigs, wild boars and bears accounted only for 2.2%, 0.7% and 0.3% of cases, respectively. This review shows the Trichinella spp. risk in the international animal and meat trade has been linked mainly to horses and only one time to wild boar, if they carcasses are not adequately tested, whereas pigs and other wild animals or their derived products infected with Trichinella spp. are unlikely to reach the international market by the official animal and

    2014-01-01

    A clear understanding of space use is required to more fully understand biological requirements of nonhuman animals in zoos, aid the design of exhibits, and maximize the animals' welfare. This study used electivity indexes to assess space use of two packs of African wild dogs (Lycaon pictus) and the appropriateness of two naturalistic, outdoor enclosures at the San Diego Zoo and Bronx Zoo. The results identified enclosure features that were both underutilized and overutilized. They suggest that replacing underutilized areas with features similar to areas that were overutilized may provide more preferred opportunities for the animals. Assessing space use of animals in human care may serve as an indicator of enclosure appropriateness and could have welfare implications. By looking at the possible reasons for area preferences, animal managers can get an idea of where improvements could be made. Designing future exhibits accordingly thus can provide possible welfare benefits for the animals concerned. PMID:24665950

    Acquired antibiotic resistances have been reported in lactobacilli of various animal and food sources, but there are no data from wild boar. The objective was a preliminary examination of the antibiotic resistance prevalence of intrinsically vancomycin-resistant lactobacilli isolated from wild boar intestines and analysis of the genetic determinants implicated. Out of three wild boars, 121 lactobacilli were recovered and grouped according to their whole cell protein patterns. Initial phenotypic screening revealed that all were susceptible to erythromycin (2 μg/ml), but 30 were resistant to tetracycline (32 μg/ml). Based on Randomly Amplified Polymorphic DNA-PCR clustering, 64 strains were selected as representative genotypes for identification and minimum inhibitory concentration (MIC) determination. Partial 16S rRNA gene sequencing identified four species: (i) L. mucosae (n=57), (ii) L. reuteri (n=47), (iii) L. fermentum (n=12), and (iv) L. murinus (n=5). Most heterofermentative strains displayed low MICs for ampicillin (AMP), chloramphenicol (CHL), streptomycin (STR), kanamycin (KAN), gentamicin (GEN), erythromycin (ERY), quinupristin/dalfopristin (Q/D), and clindamycin (CLI). Atypical MICs were found mainly in L. mucosae and L. reuteri for TET, KAN, STR, AMP and CHL, but except the TET MICs of L. mucosae mostly at low level. L. murinus strains revealed atypical MICs for aminoglycosides, and/or CHL, AMP, CLI. PCR screening detected tet(W) in 12 and tet(M) in one of heterofermentative strains, as well as the aph(3')-III kanamycin gene in L. murinus. This is the first report showing acquired antibiotic resistance determinants in intestinal lactobacilli of wild boar origin. PMID:24326231

  7. Oscar Wilde and the brain cell.

    Science.gov (United States)

    Cohn, Elisha

    2013-01-01

    This chapter considers Oscar Wilde's interest in the brain cell as an aesthetic object. Offering an account of Wilde's career that analyzes his early interest in physiology and philosophy, this chapter argues that Wilde's uniquely aesthetic take on the brain suggests that he rejects an account of the self as autonomous or self-determining. For many late Victorians brain science threatened both the freedom of human action and the legitimacy of beauty because it had the potential to invalidate conscious experience. But writers whose work Wilde knew, like John Ruskin, W. K. Clifford, and John Tyndall, avoided the despair of materialism by using aesthetic terms in their own discussions of life's invisible materials. Wilde's art collaborates with the contemporary sciences. His depictions of the cell direct the senses to a new field of being that emphasizes the molecular life all humans have in common, in which individual responsibility and activity matter less than the necessity of beauty.

  8. A stated preference investigation into the Chinese demand for farmed vs. wild bear bile.

    2011-01-01

    Farming of animals and plants has recently been considered not merely as a more efficient and plentiful supply of their products but also as a means of protecting wild populations from that trade. Amongst these nascent farming products might be listed bear bile. Bear bile has been exploited by traditional Chinese medicinalists for millennia. Since the 1980s consumers have had the options of: illegal wild gall bladders, bile extracted from caged live bears or the acid synthesised chemically. Despite these alternatives bears continue to be harvested from the wild. In this paper we use stated preference techniques using a random sample of the Chinese population to estimate demand functions for wild bear bile with and without competition from farmed bear bile. We find a willingness to pay considerably more for wild bear bile than farmed. Wild bear bile has low own price elasticity and cross price elasticity with farmed bear bile. The ability of farmed bear bile to reduce demand for wild bear bile is at best limited and, at prevailing prices, may be close to zero or have the opposite effect. The demand functions estimated suggest that the own price elasticity of wild bear bile is lower when competing with farmed bear bile than when it is the only option available. This means that the incumbent product may actually sell more items at a higher price when competing than when alone in the market. This finding may be of broader interest to behavioural economists as we argue that one explanation may be that as product choice increases price has less impact on decision making. For the wildlife farming debate this indicates that at some prices the introduction of farmed competition might increase the demand for the wild product. PMID:21799733

  9. Mortality and the magnitude of the "wild effect" in chimpanzee tooth emergence.

    Science.gov (United States)

    Smith, B Holly; Boesch, Christophe

    2011-01-01

    Age of tooth emergence is a useful measure of the pace of life for primate species, both living and extinct. A recent study combining wild chimpanzees of the Taï Forest, Gombe, and Bossou by Zihlman et al. (2004) suggested that wild chimpanzees erupt teeth much later than captives, bringing into question both comparisons within the hominin fossil record and assessment of chimpanzees. Here, we assess the magnitude of the "wild effect" (the mean difference between captive and wild samples expressed in standard deviation units) in these chimpanzees. Tooth emergence in these wild individuals is late, although at a more moderate level than previously recorded, with a mean delay conservatively estimated at about 1 SD compared to the captive distributions. The effect rises to 1.3 SD if we relax criteria for age estimates. We estimate that the mandibular M1 of these wild chimpanzees emerges at about 3 (2)/(3)-3 ¾ years of age. An important point, often ignored, is that these chimpanzees are largely dead of natural causes, merging the effect of living wild with the effect of early death. Evidence of mortality selection includes, specifically: younger deaths appear to have been more delayed than the older in tooth emergence, more often showed evidence of disease or debilitation, and revealed a higher occurrence of dental anomalies. Notably, delay in tooth emergence for live-captured wild baboons appears lower in magnitude (ca. 0.5 SD) and differs in pattern. Definitive ages of tooth emergence times in living wild chimpanzees must be established from the study of living animals. The fossil record, of course, consists of many dead juveniles; the present study has implications for how we evaluate them. PMID:21071064

    2010-07-01

    Wild animal populations face threats from pathogens from both intentionally released captive animals and domestic animals that accompany human settlements. From December 2004 through August 2005, we studied free living macaws and parrots in the Tambopata National Reserve in the Peruvian Amazon and semicaptive domestic fowl in human settlements adjacent to the reserve. In 1992-1993, large macaws (Aras spp.) that were serologically positive for Salmonella Pullorum were released into this reserve, which hosts dense populations of free-living parrots and macaws. We collected cloacal swabs from 64 birds and cultured for Salmonella spp. via standard laboratory methods. All 35 psittacines tested were culture negative for Salmonella spp., while 31% of 29 domestic fowl were culture positive. Our findings suggest that the domestic fowl that accompany human settlement in this region carry and shed Salmonella spp. that could threaten wild bird populations in and around the reserve.

    Full Text Available IntroductionPeste des petits ruminants (PPR is the most contagious and extremely infectious respiratory diseases in goats and sheep and is most common in West and Central Africa, Middle East and Southern Asia; it spreads rapidly regardless of country borders (1. A serological and virological outbreak of PPR was identified in Ilam province, Iran near the Iraqi border in 1995. Since then, despite all control measures, numerous incidents of the disease have been reported throughout the country (2. Between 1995 and 2004, vaccination of sheep and goats was performed by cell cultured rinderpest (RP vaccine; the small ruminants started to be vaccinated from early 2005 (2. In spite of vaccination of susceptible animals and application of some containment measures, PPR spread through the whole country, infecting every province with fluctuating prevalence and continuity. The cause of this failure might be related to the fact that well-designed control program in the country was not carried out appropriately and vaccination schedule was not covered abundantly. For instance in 2011, just over 3.5 million small ruminants received vaccine from an estimated National population of just fewer than 80 million animals (3. Some species of animal , e.g. such as gazelles, goats and sheep, that are relatively prevalent in Middle Eastern countries especially in Iran are believed to be immune to PPR infection (4. The wildlife in Iran consists of several animal species that include bears, gazelles, foxes, and also domestic animals including sheep, goats, cattle, and camels.It is believed that PPR virus circulates in domestic ruminants and acts as a potential source of virus for wild animal species in wildlife and the role of domestic small ruminants in the spread of the disease to wild ruminants is clear. It is quite possible that in cases of pastures exchange between domestic and wild animals, the spread of PPR is facilitated between the two populations (5. In Iran

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available Animism is often described as the imputation of life to inert objects. Such imputation is more typical of people in western societies who dream of finding life on other planets than of indigenous peoples to whom the label of animism has classically been applied. These peoples are united not in their beliefs but in a way of being that is alive and open to a world in continuous birth. In this animic ontology, beings do not propel themselves across a ready-made world but rather issue forth through a world-in-formation, along the lines of their relationships. To its inhabitants this weather-world, embracing both sky and earth, is a source of astonishment but not surprise. Re-animating the ‘western’ tradition of thought means recovering the sense of astonishment banished from offi cial science.

More than 80 % of samples came from following districts of Slovakia: Ziar nad Hronom, Prievidza, Martin, Rimavska Sobota, Senica, Banska Bystrica, Roznava, Poprad and Spisska Nova Ves. All measurements were carried out using gamma spectrometric system equipped with 4 high purity germanium detectors. Presented results were obtained using statistical evaluation for left-censored log-normal distribution of data sets. Overall activities of Cs-137 found in red deer and wild boards in Slovakia are considerably lower, than activities reported in game animals from some parts of Northern Moravia, Southern Bohemia and Austria. While the mean activities in red deer show a decreasing tendency, mean activities of wild boar are low, but with higher occurrence of extreme values, and hence, higher variance. The observed difference could be explained by the feeding habits of wild boar: grubbing in the ground for worms, larvae, roots, etc. can lead to presence of up to 20 % of contaminated soil in their stomach. At the same time wild boars often graze farmlands, where the activity of the Cs-137 in the top soil layer is reduced by ploughing and radiocesium on clay particles. Fraction of farmlands in the home range of the wild boars and the time of shooting could contribute to observed variations in radiocesium activity. (J.K.) 2 tabs., 3 refs

    International audience In computer vision, the animation of objects has attracted a lot attention, specially the animations of 3D face models. The animation of face models requires in general to manually adapt each generic movement (open/close mouth) to each specific head geometry. In this work we propose a technique for the animation of any face model avoiding most of the manual intervention. In order to achieve this we assume that: (1) faces, despite obvious differences are quite similar...

  5. Linkage disequilibrium in wild mice.

    Full Text Available Crosses between laboratory strains of mice provide a powerful way of detecting quantitative trait loci for complex traits related to human disease. Hundreds of these loci have been detected, but only a small number of the underlying causative genes have been identified. The main difficulty is the extensive linkage disequilibrium (LD in intercross progeny and the slow process of fine-scale mapping by traditional methods. Recently, new approaches have been introduced, such as association studies with inbred lines and multigenerational crosses. These approaches are very useful for interval reduction, but generally do not provide single-gene resolution because of strong LD extending over one to several megabases. Here, we investigate the genetic structure of a natural population of mice in Arizona to determine its suitability for fine-scale LD mapping and association studies. There are three main findings: (1 Arizona mice have a high level of genetic variation, which includes a large fraction of the sequence variation present in classical strains of laboratory mice; (2 they show clear evidence of local inbreeding but appear to lack stable population structure across the study area; and (3 LD decays with distance at a rate similar to human populations, which is considerably more rapid than in laboratory populations of mice. Strong associations in Arizona mice are limited primarily to markers less than 100 kb apart, which provides the possibility of fine-scale association mapping at the level of one or a few genes. Although other considerations, such as sample size requirements and marker discovery, are serious issues in the implementation of association studies, the genetic variation and LD results indicate that wild mice could provide a useful tool for identifying genes that cause variation in complex traits.

    Small ruminant lentivirus (SRLV) infection causes losses in the small ruminant industry due to reduced animal production and increased replacement rates. Infection of wild ruminants in close contact with infected domestic animals has been proposed to play a role in SRLV epidemiology, but studies are limited and mostly involve hybrids between wild and domestic animals. In this study, SRLV seropositive red deer, roe deer and mouflon were detected through modified ELISA tests, but virus was not successfully amplified using a set of different PCRs. Apparent restriction of SRLV infection in cervids was not related to the presence of neutralizing antibodies. In vitro cultured skin fibroblastic cells from red deer and fallow deer were permissive to the SRLV entry and integration, but produced low quantities of virus. SRLV got rapidly adapted in vitro to blood-derived macrophages and skin fibroblastic cells from red deer but not from fallow deer. Thus, although direct detection of virus was not successfully achieved in vivo, these findings show the potential susceptibility of wild ruminants to SRLV infection in the case of red deer and, on the other hand, an in vivo SRLV restriction in fallow deer. Altogether these results may highlight the importance of surveilling and controlling SRLV infection in domestic as well as in wild ruminants sharing pasture areas, and may provide new natural tools to control SRLV spread in sheep and goats.

    Full Text Available Disease can cause declines in wildlife populations and significantly threaten their survival. Recent expansion of human and domestic animal populations has made wildlife more susceptible to transmission of pathogens from domestic animal hosts. We conducted a pathogen surveillance and mortality survey for the population of African wild dogs (Lycaon pictus in KwaZulu-Natal (KZN, South Africa, from January 2006–February 2007. Samples were obtained from 24 wild dogs for canine distemper virus (CDV and canine parvovirus (CPV serological testing. Data were collected on the presence of CDV, CPV, and rabies virus in the KZN domestic dog (Canis familiaris population from 2004–06. The presence of these pathogens was confirmed in domestic dogs throughout KZN. Wild dogs exhibited 0% and 4.2% prevalence for CDV and CPV antibodies, respectively. In 2006 the largest wild dog pack in KZN was reduced from 26 individuals to a single animal; disease due to rabies virus was considered the most probable cause. This study provides evidence that CDV, CPV and rabies are potential threats to African wild dog conservation in KZN. The most economical and practical way to protect wild dogs from canine pathogens may be via vaccination of sympatric domestic dogs; however, such programmes are currently limited.

    Declines in economic activity and associated changes in human livelihood strategies can increase threats of species overexploitation. This is exemplified by the effects of economic crises, which often drive intensification of subsistence poaching and greater reliance on natural resources. Whereas development theory links natural resource use to social-economic conditions, few empirical studies of the effect of economic downturns on wild animal species have been conducted. I assessed the relations between African elephant (Loxodonta africana) mortality and human-caused wounds in Samburu, Kenya and (1) livestock and maize prices (measures of local economic conditions), (2) change in national and regional gross domestic product (GDP) (measures of macroeconomic conditions), and (3) the normalized difference vegetation index (NDVI) (a correlate of primary productivity). In addition, I analyzed household survey data to determine the attitudes of local people toward protected areas and wild animals in the area. When cattle prices in the pastoralist study region were low, human-caused wounds to and adult mortality of elephants increased. The NDVI was negatively correlated with juvenile mortality, but not correlated with adult mortality. Changes in Kenyan and East Asian (primary market for ivory) GDP did not explain significant variation in mortality. Increased human wounding of elephants and elephant mortality during periods of low livestock prices (local economic downturns) likely reflect an economically driven increase in ivory poaching. Local but not macroeconomic indices explained significant variation in mortality, likely due to the dominance of the subsistence economy in the study area and its political and economic isolation. My results suggest economic metrics can serve as effective indicators of changes in human use of and resulting effects on natural resources. Such information can help focus management approaches (e.g., antipoaching effort or proffering of

    Hepatitis E virus (HEV) causes acute hepatitis E in humans in developing countries, but sporadic and autochthonous cases do also occur in industrialized nations. In Europe, food-borne zoonotic transmission of genotype 3 (gt3) has been associated with the consumption of raw and undercooked products from domestic pig and wild boar. As shown recently, naturally acquired HEV gt3 replicates efficiently in experimentally infected wild boar and is transmissible from a wild boar to domestic pigs. Generally, following an acute infection swine suffer from a transient febrile illness and viremia in connection with fecal virus shedding. However, little is known about sub-acute or chronic HEV infections in swine, and how and where HEV survives the immune response. In this paper, we describe the incidental finding of a chronic HEVgt3 infection in two naturally infected European wild boar which were raised and housed at FLI over years. The wild boar displayed fecal HEV RNA excretion and viremia over nearly the whole observation period of more than five months. The animal had mounted a substantial antibody response, yet without initial clearance of the virus by the immune system. Further analysis indicated a subclinical course of HEV with no evidence of chronic hepatitis. Additionally, we could demonstrate that this chronic wild boar infection was still transmissible to domestic pigs, which were housed together with this animal. Sentinel pigs developed fecal virus shedding accompanied by seroconversion. Wild boar should therefore be considered as an important reservoir for transmission of HEV gt3 in Europe. PMID:26344041

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

    International Nuclear Information System (INIS)

    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.

    Full Text Available ANIMAL metaphors are conventional in many languages and their metaphorical use is not limited only to human beings, non-physical domains may also be understood in terms of the assumed properties of animals. Set within the wider theoretical framework of Cognitive Theory of Metaphor, this paper deals with the conceptualisation of INFLATION as an ANIMAL in English. We focus on the INFLATION IS A FEROCIOUS ANIMAL metaphor, in which the most salient properties of wild animals as a source domain are mapped onto the abstract and complex target domain, INFLATION, producing various conceptual mappings, which refer to the ways wild animals move, look, sound, eat/are fed, attack and are controlled. We show how the INFLATION IS A FEROCIOUS ANIMAL metaphor functions within popular economic discourse, as well as how it structures our thinking about inflation, a dangerous phenomenon which poses a potential threat to every economy in the world.

  19. Wild reindeer in Norway – population ecology, management and harvest

    Full Text Available Wild reindeer in Norway, presently (winter 2005-06 numbering some 25 000 animals, are found in 23 more or less separated areas in the mountainous southern part of the country (see map in appendix. All herds are hunted and management is organized in close cooperation between owner organizations and state agencies. I will provide a historical review of the wild reindeer management and research in Norway and conclude with the present situation. We identify 3 types of wild reindeer on basis of their origin: (1 the original wild reindeer with minor influence from previous domestic reindeer herding activities (Snøhetta, Rondane and Sølenkletten, (2 wild reindeer with some influx of animals from past domestic reindeer herding in the area (Nordfjella, Hardangervidda, Setesdal-Ryfylke and (3 feral reindeer with a domesticated origin (reindeer released or escaped from past reindeer husbandry units; Forolhogna, Ottadalen North and Ottadalen South, Norefjell-Reinsjøfjell and several smaller areas. In Norway, genetic origin (wild or domesticated, body size and reproductive performance of reindeer differ among areas. Feral reindeer have higher body weights and enjoy higher reproductive rates than their originally wild counterparts. These differences may partially be explained by differences in food quality and availability among the populations. However, there is a growing suspicion that other explanatory factors are also involved. Wild reindeer are more vigilant and show longer fright and flight distances than feral reindeer. Number of animals harvested was 4817, or ca. 20% of the total population in 2005, but varies between 40% in feral reindeer areas to below 20% in some of the "wild" reindeer areas. Causal factors behind this variation include differences in age at maturation, postnatal calf mortality and herd structure. The Norwegian Institute for nature research (NINA in cooperation with the Directorate for nature management (DN allocate considerable

    The aim of this study was to evaluate the epidemiological situation of swine influenza virus (SIV) infections in different wild boar populations in Germany based on a serological surveillance in some Bundeslaender (federal states) in connection with virological investigations in wild boar shot in Northern Germany (Mecklenburg-Western Pomerania, district of Nordvorpommern). Altogether, 1245 sera from wild boar were tested using the hemagglutination inhibition test. The established seroprevalence rate was low (on average 5.2%). Antibodies were only detected against the subtypes H1N1 and H3N2 showing differences between wild boar populations and age classes. The virological investigation of samples derived from lungs of wild boar shot in Mecklenburg-Western Pomerania, district of Nordvorpommern (n=242), revealed that the virus prevalence (two virologically positive animals, 0.8%) was very low. Based on serological typing, the isolated SIV was identified as subtype H3N2. Molecular biological investigations of the hemagglutinin (HA) and neuraminidase (NA) genes confirmed this result. This study suggests that SIV infections in wild boar seem to be no serious threat for domestic pigs. PMID:18440732

    Infectious disease has only recently been recognized as a major threat to the survival of Endangered chimpanzees and Critically Endangered gorillas in the wild. One potentially powerful tool, vaccination, has not been deployed in fighting this disease threat, in good part because of fears about vaccine safety. Here we report on what is, to our knowledge, the first trial in which captive chimpanzees were used to test a vaccine intended for use on wild apes rather than humans. We tested a virus-like particle vaccine against Ebola virus, a leading source of death in wild gorillas and chimpanzees. The vaccine was safe and immunogenic. Captive trials of other vaccines and of methods for vaccine delivery hold great potential as weapons in the fight against wild ape extinction. PMID:24912183

    Science.gov (United States)

    Coakley, D

    2016-05-01

    It is widely believed that Sir William Wilde's forebears were in Ireland for just two or three generations. This belief stems from a number of short biographies of Wilde which were published during his lifetime. These biographies gave different versions of the origin of the Wilde family and appear to have been generated by the creative imagination of Lady Jane Wilde or, as she was better known by her nom de plume, Speranza. She was equally imaginative in creating narratives about her own family background and in one she claimed descent from the Italian poet Dante Alighieri. So it was not a great challenge for her to invent biographies of her husband which she deemed suitable for a knight living at the prestigious address of 1 Merrion Square, leading many to believe that William and his son Oscar were more English than Irish. It was also important for Speranza to distance Sir William from any connection which the Wilde family might have had with trade.

    As many studies of cognition and behavior involve captive animals, assessing any psychological impact of captive conditions is an important goal for comparative researchers. Ferdowsian and colleagues (2011) sought to address whether captive chimpanzees show elevated signs of psychopathology relative to wild apes. They modified a checklist of diagnostic criteria for major depression and posttraumatic stress disorder in humans, and applied these criteria to various captive and wild chimpanzee populations. We argue that measures derived from human diagnostic criteria are not a powerful tool for assessing the psychological health of nonverbal animals. In addition, we highlight certain methodological drawbacks of the specific approach used by Ferdowsian and colleagues (2011). We propose that research should (1) focus on objective behavioral criteria that account for species-typical behaviors and can be reliably identified across populations; (2) account for population differences in rearing history when comparing how current environment impacts psychological health in animals; and (3) focus on how changes in current human practices can improve the well-being of both captive and wild animals.

    Circoviruses are relatively novel pathogens with increased importance in canids. In this study, we first screened the presence of dog circovirus (DogCV) by molecular methods from a total number of 389 internal organ samples originating from 277 individuals of domestic dogs and wild animals including wolves, foxes and badgers. All the animals originated from Central-Southern Italy, specifically from Abruzzi and Molise regions, areas hosting several natural parks. DogCV was detected in 9/34 wolves (P=26.4%; IC 95%: 14.6-43.1%), 8/209 dogs (P=3.8%; IC 95%: 1.9-7.3%), 0/24 foxes (P=0%; IC 95%: 0-13.8%), 1/10 badgers (P=10%; IC 95%: 1.79-40.4%). However, all DogCV positive animals were shown to be infected at least by an additional key pathogen, including canine distemper virus (CDV) and canine parvovirus type 2. All wolves, but one, presenting DogCV in the internal tissues suffered from CDV infection. The DNA purified from 17 DogCV infected organs was used for whole genome sequencing and phylogenetic analysis. PMID:26848830

  1. Identification of learning mechanisms in a wild meerkat population.

    Directory of Open Access Journals (Sweden)

    Will Hoppitt

    Full Text Available Vigorous debates as to the evolutionary origins of culture remain unresolved due to an absence of methods for identifying learning mechanisms in natural populations. While laboratory experiments on captive animals have revealed evidence for a number of mechanisms, these may not necessarily reflect the processes typically operating in nature. We developed a novel method that allows social and asocial learning mechanisms to be determined in animal groups from the patterns of interaction with, and solving of, a task. We deployed it to analyse learning in groups of wild meerkats (Suricata suricatta presented with a novel foraging apparatus. We identify nine separate learning processes underlying the meerkats' foraging behaviour, in each case precisely quantifying their strength and duration, including local enhancement, emulation, and a hitherto unrecognized form of social learning, which we term 'observational perseverance'. Our analysis suggests a key factor underlying the stability of behavioural traditions is a high ratio of specific to generalized social learning effects. The approach has widespread potential as an ecologically valid tool to investigate learning mechanisms in natural groups of animals, including humans.

    Electronic media have unlocked a hitherto largely untapped potential for swarm intelligence (SI; generally, the realisation that group living can facilitate solving cognitive problems that go beyond the capacity of single animals) in humans with relevance for areas such as company management, prediction of elections, product development and the entertainment industry. SI is a rapidly developing topic that has become a hotbed for both innovative research and wild speculation. Here, we tie together approaches from seemingly disparate areas by means of a general definition of SI to unite SI work on both animal and human groups. Furthermore, we identify criteria that are important for SI to operate and propose areas in which further progress with SI research can be made. PMID:19735961

  3. Small Animal Retinal Imaging

    Science.gov (United States)

    Choi, WooJhon; Drexler, Wolfgang; Fujimoto, James G.

    Developing and validating new techniques and methods for small animal imaging is an important research area because there are many small animal models of retinal diseases such as diabetic retinopathy, age-related macular degeneration, and glaucoma [1-6]. Because the retina is a multilayered structure with distinct abnormalities occurring in different intraretinal layers at different stages of disease progression, there is a need for imaging techniques that enable visualization of these layers individually at different time points. Although postmortem histology and ultrastructural analysis can be performed for investigating microscopic changes in the retina in small animal models, this requires sacrificing animals, which makes repeated assessment of the same animal at different time points impossible and increases the number of animals required. Furthermore, some retinal processes such as neurovascular coupling cannot be fully characterized postmortem.

  4. Animals as disgust elicitors

    2015-01-01

    This paper attempts to explain how and why nonhuman animals elicit disgust in human beings. I argue that animals elicit disgust in two ways. One is by triggering disease–protection mechanisms, and the other is by eliciting mortality salience, or thoughts of death. I discuss how these two types...... of disgust operate and defend their conceptual and theoretical coherence against common objections. I also outline an explanatory challenge for disgust researchers. Both types of disgust indicate that a wide variety of animals produce aversive and avoidant reactions in human beings. This seems somewhat odd......, given the prominence of animals in human lives. The challenge, then, is explaining how humans cope with the presence of animals. I propose, as a hypothesis for further exploration, that we cope with animals, and our disgust responses to them, by attributing mental states that mark them as inferior...

  5. Hematological profile as a crude oil exposure-related marker in wild rodents

    2013-01-01

    Full Text Available The toxicity of petroleum components is well described in the literature, especially with regard to mutagenic and carcinogenic effects. In some groups of animals, such as birds, oil exposure seems to alter blood parameters, while this relationship is poorly understood in rodents. The study aimed to investigate alterations in hematological profile in the wild rodent Calomys laucha exposed to crude oil contaminated soils. In this study, males specimens of Calomys laucha were exposed for 14 days to two soils contaminated by petroleum: (I landfarming soil, coming from a bioremediation area of contaminated soil from a Petrochemical Complex through landfarming technique and (II soil of a simulated oil spill in laboratory conditions. The animals were exposed individually in cages containing 1 kg soil with free access to food and water. Control animals were exposed to an artificial uncontaminated soil. At the end of the experiment, animals were anesthetized and blood was collected for hematological profile. The animals exposed to soil landfarming had significant reduction in the number of bands, segmented, eosinophils, monocytes, lymphocytes and increased red cell distribution width (RDW, while animals exposed to simulated soil spillage in laboratory had decreased number of bands, but an increase in the number of lymphocytes and platelets. These changes in hemostasis may indicate an early stage of the development of associated pathologies, while the hematological profile can be used as a crude oil exposure-related marker in wild rodents.

    Trichinosis is natural focal invasion in the Kursk Region. Porkworms (Trichinella) circulate in natural biocenoses among wild carnivorous mammals, wild boars, and rodents. Trichinosis cases are recorded in synanthropic animals. Carnivorous mammals form the basis for the parasitic system of trichinosis. The animals are infected with Trichinella through carnivorism, necrophagy, and cannibalism. The transport Trichinella vectors, necrophagous insects, naturally play an insignificant role-in the spread of trichinosis. Trichinella infection in animals occurs more commonly through necrophagia and cannibaism during winter months. Not only animals, but also man, play a great role in the spread of trichinosis. Infested wild and synanthropic aninals inhabiting the Kursk Region may carry the risk for Trichinella infection in the population. PMID:26827582

In Rasht and Bandar-An­zali, in Gilan Province, where experienced two large human fasciolosis outbreaks, no update information is available on ani­mal fasciolosis. Paucity of information on animal fasciolosis in these regions and its possible impacts on human fasciolo­sis called us for carrying out this study."nMethods: During 2005, coprologic surveys using flotation method were applied to fecal samples of 156 stray cattle, 171 calves, 178 sheep, 85 buffaloes, 79 horses and 10 samples from 10 different preserved animal manure collec­tions to detect Fasciola egg."nResults: Fecal samples of 32 % of sheep, 32.1% of cattle, 0% of calves, 17% of buffaloes, 50% of horses and 100% of ani­mal manure samples harbored Fasciola egg. The mean intensity of Fasciola egg per gram of feces (EPG was low (0-13."nConclusion: Fasciolosis was very prevalent among animals in studied regions. Because sheep breeding is not a common prac­tice in Rasht and Bandar -Anzali and horse population is low, cattle and to a lesser extent buffalo were the predominant reser­voir hosts of infection. Regular treatment of all animals with an effective flukicide and sanitation of animal manure through its preservation for two month should be applied in order to reduce the level of infection in animals, water, wild and culti­vated vegetables and consequently human beings.

    Between January and December 2013, the dental and periodontal health of 99 Swedish wild boars (Sus scrofa) was investigated. Sampling occurred in conjunction with routine hunting at six large estates in the southern and middle parts of Sweden. All six of the estates use supplemental feeding. The weight of the animals, their sex and their dates of death were noted. Age was estimated using tooth eruption and tooth replacement patterns. The oral cavity was inspected and abnormalities were recorded on a dental chart modified for wild boars. The findings included supernumerary teeth, absence of teeth, mild class II malocclusion, severe tooth wear, periodontitis, calculus, caries, tooth fractures and the presence of enamel defects. Swedish wild boars suffer from different dental lesions and the impact of supplemental feeding on dental and periodontal health is still to be investigated. PMID:25979683

    Viral infections are one of the leading source of mortality worldwide. The great majority of them circulate and persist in wild reservoirs and periodically spill over into humans or domestic animals. In the wild reservoirs, the progression of disease is frequently quite different from that in spillover hosts. We propose a mathematical treatment of the dynamics of viral infections in wild mammals using models with alternative outcomes. We develop and analyze compartmental epizootic models assuming permanent or temporary immunity of the individuals surviving infections and apply them to rabies in bats. We identify parameter relations that support the existing patterns in the viral ecology and estimate those parameters that are unattainable through direct measurement. We also investigate how the duration of the acquired immunity affects the disease and population dynamics. PMID:19278278

    Wild flowers in the South of Spain were screened for Enterococcus faecalis and Enterococcus faecium. Enterococci were frequently associated with prickypear and fieldpoppy flowers. Forty-six isolates, from 8 different flower species, were identified as E. faecalis (28 isolates) or E. faecium (18 isolates) and clustered in well-defined groups by ERIC-PCR fingerprinting. A high incidence of antibiotic resistance was detected among the E. faecalis isolates, especially to quinupristin/dalfopristin (75%), rifampicin (68%) and ciprofloxacin (57%), and to a lesser extent to levofloxacin (35.7%), erythromycin (28.5%), tetracycline (3.5%), chloramphenicol (3.5%) and streptomycin (3.5%). Similar results were observed for E. faecium isolates, except for a higher incidence of resistance to tetracycline (17%) and lower to erythromycin (11%) or quinupristin/dalfopristin (22%). Vancomycin or teicoplanin resistances were not detected. Most isolates (especially E. faecalis) were proteolytic and carried the gelatinase gene gelE. Genes encoding other potential virulence factors (ace, efaA (fs), ccf and cpd) were frequently detected. Cytolysin genes were mainly detected in a few haemolytic E. faecium isolates, three of which also carried the collagen adhesin acm gene. Hyaluronidase gene (hyl ( Efm )) was detected in two isolates. Many isolates produced bacteriocins and carried genes for enterocins A, B, and L50 mainly. The similarities found between enterococci from wild flowers and those from animal and food sources raise new questions about the puzzling lifestyle of these commensals and opportunistic pathogens.

    2015-07-01

    Understanding animal episodic-like memory is important for tracing the evolution of the human mind. However, our knowledge about the existence and nature of episodic-like memory in non-human primates is minimal. We observed the behaviour of a wild male chacma baboon faced with a trade-off between protecting his stationary group from aggressive extra-group males and foraging among five out-of-sight platforms. These contained high-priority food at a time of natural food shortage. In 10 morning and eight evening trials, the male spontaneously visited the platforms in five and four different sequences, respectively. In addition, he interrupted foraging sequences at virtually any point on eight occasions, returning to the group for up to 2 h. He then visited some or all of the remaining platforms and prevented revisits to already depleted ones, apparently based on his memory for the previous foraging episode about food value, location, and time. Efficient use of memory allowed him to keep minimal time absent from his group while keeping food intake high. These findings support the idea that episodic-like memory offers an all-purpose solution to a wide variety of problems that require flexible, quick, yet precise decisions in situations arising from competition for food and mates in wild primates.

    2015-01-01

    Full Text Available A female coyote (Canis latrans was fatally injured by a vehicle on a road in San Luis Potosi, Mexico. Because of deteriorating clinical signs, the animal was euthanized. Postmortem examination of the lungs showed numerous small multifocal white nodules (0.5–1 cm diameter disseminated throughout. Histopathologic examination revealed multifocal coalescing granulomas with abundant macrophages, numerous neutrophils, fibroblasts, plasma cells, and lymphocytes. Abundant intracellular and extracellular thick-walled, refractile, spherical yeasts (10–15 μm were observed within the granulomas. The yeasts were intensely PAS-positive, with granular protoplasm. Broad-based single budding yeasts were occasionally present. Based on the microscopic findings of the pulmonary lesions and the morphological features of the organism, a diagnosis of chronic pyogranulomatous pneumonia caused by Blastomyces dermatitidis was made. To our knowledge, the case described herein is the first report of pulmonary blastomycosis in a wild coyote.

    Chapparvovirus, a recently determined new genus in the family Parvoviridae, can infect many species of animals including bats, chickens, and pigs. Here, using viral metagenomics method, we identified a novel Chapparvovirus from feces of wild rats and designated it as rat parvovirus 2 (RPV2). The nearly complete genome of RPV2 is 4222-nt long and includes two ORFs encoding a 654-aa nonstructural protein 1 (NS1) and a 472-aa capsid protein (VP), respectively. Phylogenetic analysis over the amino acid sequence of the NS1 showed that RPV2 clustered with Eidolon helvum parvovirus 2 (EHPV2), porcine parvovirus 7 (PPV7), and turkey parvovirus 1 (TP1), forming a separate clade. Sequence analysis indicated that the NS1 protein of RPV2 shared the highest amino acid sequence identity (51 %) with that of EHPV2. According to the genetic distance-based criteria, RPV2 identified here belongs to a novel species of Chapparvovirus. PMID:27473724

  8. 'Eavesdropping' in wild rough-toothed dolphins (Steno bredanensis)?

    2006-03-22

    Several authors suggest that dolphins use information obtained by eavesdropping on echoes from sonar signals of conspecifics, but there is little evidence that this strategy is used by dolphins in the wild. Travelling rough-toothed dolphins (Steno bredanensis) either exhibit asynchronous movements or an extremely synchronized swimming behaviour in tight formations, which we expect to facilitate eavesdropping. Therefore, we determined, whether either one or more dolphins were echolocating in subgroups that were travelling with asynchronous and synchronized movements. Since, the number of recording sequences in which more than one animal produced sonar signals was significantly lower during synchronized travel, we conclude that the other members of a subgroup might get information on targets ahead by eavesdropping. Synchronized swimming in tight formations might be an energetic adaptation for travelling in a pelagic dolphin species that facilitates eavesdropping. PMID:17148311

  9. Radiation effects in wild terrestrial vertebrates - the EPIC collection

    International Nuclear Information System (INIS)

    The paper presents data on radiation effects in populations of wild vertebrate animals inhabiting contaminated terrestrial ecosystems. The data were extracted from the database 'Radiation effects on biota', compiled within the framework of the EC Project EPIC (2000-2003). The data collection, based on publications in Russian, demonstrates radiation effects in the areas characterized with high levels of radionuclides (Kyshtym radioactive trace; 'spots' of enhanced natural radioactivity in the Komi region of Russia; territories contaminated from the Chernobyl fallout). The data covers a wide range of exposures from acute accidental irradiation to lifetime exposures at relatively low dose rates. Radiation effects include mortality, changes in reproduction, decrease of health, ecological effects, cytogenetic effects, adaptation to radiation, and others. Peculiarities of radiation effects caused by different radionuclides are described, also the severity of effects as they appear in different organisms (e.g. mice, frogs, birds, etc.)

    Rabies is an endemic disease in Brazil, where it is considered a serious public health problem. Although the number of human and dog-transmitted cases has declined in recent decades, rabies in wildlife has emerged considerably. Among the sylvatic animals, wild canids have been considered important hosts of the rabies virus. We performed a retrospective study of reported cases of rabies in wild canids and human victims in Ceará state (Northeast Brazil) during 2003 to 2013. Information was provided by governmental laboratories involved in rabies detection and by the Ministry of Health. From January 2003 to December 2013, a total of 11 931 animal samples were examined for rabies. Positivity were detected in 438 samples (3.67%), of which 229 (52.28%) were domestic animals, 105 (23.97%) wild canids and 104 (23.74%) other wild animals (bats, marmosets and raccoons). Approximately 33% of wild canids surveyed (n = 317) were positive for rabies. During the studied period, a total of 1923 attacks on humans by wild canids were registered. Males (n = 1405) were more affected than females (n = 520; 72.98% versus 27.01%), and the median age of all cases was 36.5 years. Injuries to individuals up to 19 years old corresponded to approximately 30% (n = 565) of all cases. Most of the victims lived in rural areas (72.46%; n = 1395), and the majority showed bites (81.13%; n = 1677) or scratches (12.23%; n = 253). Injuries were considered profound (52.1%; n = 1003), superficial (40.91; n = 788) or multiple with severe laceration (6.98%; n = 134). Only 1300 (67.53%) victims were enrolled for the complete rabies post-exposure prophylaxis scheme. Data from the present study confirm that wild canids are important hosts of rabies virus in northeastern Brazil and jeopardize rabies control in this area. Local authorities should focus their efforts in education of health professionals. In addition, strategies should be formulated to preserve wildlife. PMID:26815766

    Toxoplasma gondii is a zoonotic intracellular protozoan parasite of worldwide distribution that infects many species of warm-blooded animals, including birds. To date, there is scant information about the seropositivity of T. gondii and the risk factors associated with T. gondii infection in wild bird populations. In the present study, T. gondii infection was evaluated on sera obtained from 1079 wild birds belonging to 56 species (including Falconiformes (n=610), Strigiformes (n=260), Ciconiiformes (n=156), Gruiformes (n=21), and other orders (n=32), from different areas of Spain. Antibodies to T. gondii (modified agglutination test, MAT titer ≥1:25) were found in 282 (26.1%, IC(95%:)23.5-28.7) of the 1079 birds. This study constitute the first extensive survey in wild birds species in Spain and reports for the first time T. gondii antibodies in the griffon vulture (Gyps fulvus), short-toed snake-eagle (Circaetus gallicus), Bonelli's eagle (Aquila fasciata), golden eagle (Aquila chrysaetos), bearded vulture (Gypaetus barbatus), osprey (Pandion haliaetus), Montagu's harrier (Circus pygargus), Western marsh-harrier (Circus aeruginosus), peregrine falcon (Falco peregrinus), long-eared owl (Asio otus), common scops owl (Otus scops), Eurasian spoonbill (Platalea leucorodia), white stork (Ciconia ciconia), grey heron (Ardea cinerea), common moorhen (Gallinula chloropus); in the International Union for Conservation of Nature (IUCN) "vulnerable" Spanish imperial eagle (Aquila adalberti), lesser kestrel (Falco naumanni) and great bustard (Otis tarda); and in the IUCN "near threatened" red kite (Milvus milvus). The highest seropositivity by species was observed in the Eurasian eagle owl (Bubo bubo) (68.1%, 98 of 144). The main risk factors associated with T. gondii seropositivity in wild birds were age and diet, with the highest exposure in older animals and in carnivorous wild birds. The results showed that T. gondii infection is widespread and can be at a high level in

    One hundred fifty-three Mycobacterium bovis strains from cattle, various animal species from zoos and wild parks, and humans were analyzed for three different genetic markers for use in the epidemiology of bovine tuberculosis. M. bovis strains isolated from cattle were found to carry a single IS6110 element, whereas the majority of strains from other animals such as antelopes, monkeys, and seals harbored multiple IS6110 elements, suggesting that the reservoirs in cattle and wild animals are s...

  14. Non-invasive genetic monitoring of wild central chimpanzees.

    Full Text Available BACKGROUND: An assessment of population size and structure is an important first step in devising conservation and management plans for endangered species. Many threatened animals are elusive, rare and live in habitats that prohibit directly counting individuals. For example, a well-founded estimate of the number of great apes currently living in the wild is lacking. Developing methods to obtain accurate population estimates for these species is a priority for their conservation management. Genotyping non-invasively collected faecal samples is an effective way of evaluating a species' population size without disruption, and can also reveal details concerning population structure. METHODOLOGY/PRINCIPAL FINDINGS: We opportunistically collected wild chimpanzee faecal samples for genetic capture-recapture analyses over a four-year period in a 132 km(2 area of Loango National Park, Gabon. Of the 444 samples, 46% yielded sufficient quantities of DNA for genotyping analysis and the consequent identification of 121 individuals. Using genetic capture-recapture, we estimate that 283 chimpanzees (range: 208-316 inhabited the research area between February 2005 and July 2008. Since chimpanzee males are patrilocal and territorial, we genotyped samples from males using variable Y-chromosome microsatellite markers and could infer that seven chimpanzee groups are present in the area. Genetic information, in combination with field data, also suggested the occurrence of repeated cases of intergroup violence and a probable group extinction. CONCLUSIONS/SIGNIFICANCE: The poor amplification success rate resulted in a limited number of recaptures and hence only moderate precision (38%, measured as the entire width of the 95% confidence interval, but this was still similar to the best results obtained using intensive nest count surveys of apes (40% to 63%. Genetic capture-recapture methods applied to apes can provide a considerable amount of novel information on

  15. Visual laterality of calf-mother interactions in wild whales.

    Full Text Available BACKGROUND: Behavioral laterality is known for a variety of vertebrate and invertebrate animals. Laterality in social interactions has been described for a wide range of species including humans. Although evidence and theoretical predictions indicate that in social species the degree of population level laterality is greater than in solitary ones, the origin of these unilateral biases is not fully understood. It is especially poorly studied in the wild animals. Little is known about the role, which laterality in social interactions plays in natural populations. A number of brain characteristics make cetaceans most suitable for investigation of lateralization in social contacts. METHODOLOGY/PRINCIPAL FINDINGS: Observations were made on wild beluga whales (Delphinapterus leucas in the greatest breeding aggregation in the White Sea. Here we show that young calves (in 29 individually identified and in over a hundred of individually not recognized mother-calf pairs swim and rest significantly longer on a mother's right side. Further observations along with the data from other cetaceans indicate that found laterality is a result of the calves' preference to observe their mothers with the left eye, i.e., to analyze the information on a socially significant object in the right brain hemisphere. CONCLUSIONS/SIGNIFICANCE: Data from our and previous work on cetacean laterality suggest that basic brain lateralizations are expressed in the same way in cetaceans and other vertebrates. While the information on social partners and novel objects is analyzed in the right brain hemisphere, the control of feeding behavior is performed by the left brain hemisphere. Continuous unilateral visual contacts of calves to mothers with the left eye may influence social development of the young by activation of the contralateral (right brain hemisphere, indicating a possible mechanism on how behavioral lateralization may influence species life and welfare. This hypothesis is

    In Central Europe the wild boar population is permanently growing and consequently Cf foodborne infections. In this study serological and molecular detection of Toxoplasma gondii and Neospora caninum in wild boars was evaluated. Moreover, same samples were screened for the presence and genetic variability of tick-borne bacterium Anaplasma phagocytophilum. Blood samples collected from 113 wild boars from Southern Slovakia were examined for antibodies to T. gondii by indirect and to N. caninum by competitive ELISA. The presence of parasitic DNA in blood samples was determined by standard or real time PCR techniques. Antibodies against T. gondii and N. caninum were detected in 45 (39.8%) and 38 (33.6%) animals, respectively. Females were more frequently infected for both pathogens than males. The high seropositivity against both coccidia indicates a permanent occurrence of these pathogens in the studied locality. T. gondii DNA was confirmed in five seropositive boars (4.4%) and N. caninum in 23 blood samples (20.4%). Three out of 23 N. caninum PCR positive animals did not show seropositivity. Three out of 113 blood samples of wild boars were positive for A. phagocytophilum (2.7%). The obtained A. phagocytophilum sequences were 100% identical with GenBankTM isolates from Slovak dog (KC985242); German horse (JF893938) or wild boar (EF143810) and red deer (EF143808) from Poland. Coinfections of T. gondii with N. caninum and N. caninum with A. phagocytophilum were detected in single cases. Results suggest a potential zoonotic risk of toxoplasmosis transmission to humans and the spread of neosporosis to farm animals. PMID:27078648

    DNAs from four wild chimpanzees (Pan troglodytes schweinfurthi) from eastern Africa were screened for 14 DNA viruses and retroviruses. Between two and three viruses were found in each animal. An entire hepatitis B virus (HBV) genome was amplified and sequenced from samples taken from one animal. This indicates that HBV is distributed across the entire range of chimpanzee habitats.
