The migratory patterns of animals are changing in response to global environmental change with many species forming resident populations in areas where they were once migratory. The white stork (Ciconia ciconia) was wholly migratory in Europe but recently guaranteed, year-round food from landfill sites has facilitated the establishment of resident populations in Iberia. In this study 17 resident white storks were fitted with GPS/GSM data loggers (including accelerometer) and tracked for 9.1 ± 3.7 months to quantify the extent and consistency of landfill attendance by individuals during the non-breeding and breeding seasons and to assess the influence of landfill use on daily distances travelled, percentage of GPS fixes spent foraging and non-landfill foraging ranges. Resident white storks used landfill more during non-breeding (20.1 % ± 2.3 of foraging GPS fixes) than during breeding (14.9 % ± 2.2). Landfill attendance declined with increasing distance between nest and landfill in both seasons. During non-breeding a large percentage of GPS fixes occurred on the nest throughout the day (27 % ± 3.0 of fixes) in the majority of tagged storks. This study provides first confirmation of year-round nest use by resident white storks. The percentage of GPS fixes on the nest was not influenced by the distance between nest and the landfill site. Storks travelled up to 48.2 km to visit landfills during non-breeding and a maximum of 28.1 km during breeding, notably further than previous estimates. Storks nesting close to landfill sites used landfill more and had smaller foraging ranges in non-landfill habitat indicating higher reliance on landfill. The majority of non-landfill foraging occurred around the nest and long distance trips were made specifically to visit landfill. The continuous availability of food resources on landfill has facilitated year-round nest use in white storks and is influencing their home ranges and movement behaviour. White

Full Text Available The authors show a preliminary study regarding the influence of the weather on the flight (soaring, gliding and flapping flight of the white storks (Ciconia ciconia in the spring migration across the Doamnei River hydrographical basin. The research is based on 289 observations and 3153 individuals observed during 1998 – 2010. The lapse of time, the temperature of the air, the atmospheric nebulosity, the type of clouds, and the wind intensity were considered. We stated that the presence of the ascendant air played a major role in the migratory flight, this rising air being used by birds in their economical flight that combine the soaring flight and the gliding one.

Full Text Available BACKGROUND/OBJECTIVE: Exposure to environmental contaminants may result in reduced reproductive success and long-lasting population declines in vertebrates. Emerging data from laboratory studies on model species suggest that certain life-stages, such as development, should be of special concern. However, detailed investigations of long-term consequences of developmental exposure to environmental chemicals on breeding performance are currently lacking in wild populations of long-lived vertebrates. Here, we studied how the developmental exposure to a mine spill (Aznalcóllar, SW Spain, April 1998 may affect fitness under natural conditions in a long-lived bird, the White Stork (Ciconia ciconia. METHODOLOGY: The reproductive performance of individually-banded storks that were or not developmentally exposed to the spill (i.e. hatched before or after the spill was compared when these individuals were simultaneously breeding during the seven years after the spill occurred (1999-2005. PRINCIPAL FINDINGS: Female storks developmentally exposed to the spill experienced a premature breeding senescence compared with their non-developmentally exposed counterparts, doing so after departing from an unusually higher productivity in their early reproductive life (non-developmentally exposed females: 0.5 ± 0.33SE fledglings/year at 3-yr old vs. 1.38 ± 0.31SE at 6-7 yr old; developmentally exposed females: 1.5 ± 0.30SE fledglings/year at 3-yr old vs. 0.86 ± 0.25SE at 6-7 yr old. CONCLUSIONS/SIGNIFICANCE: Following life-history theory, we propose that costly sub-lethal effects reported in stork nestlings after low-level exposure to the spill-derived contaminants might play an important role in shaping this pattern of reproduction, with a clear potential impact on population dynamics. Overall, our study provides evidence that environmental disasters can have long-term, multigenerational consequences on wildlife, particularly when affecting developing individuals

Changes in nest density and reproductive success of a free–ranging population of white stork (Ciconia ciconia) in the Gardens of ZooBotánico Jerez (Cádiz) were studied from 1990 to 2013. Reproductive data (number of nests and number of chicks per nest) and the effect of rainfall on the reproductive success were analyzed. In addition, a number of chicks were colour–ringed each year and the recovery data were also analyzed. The number of nests found in the area steadily increased during the study period and varied greatly from year to year from 2001 onwards (mean 19, range = 4–35, N = 22 years). Reproductive success also varied greatly among years. Overall, the mean number of chicks per nest was 1.78 ± 1.2 (range = 0–5, N = 439 nests).Reproductive success was strongly influenced by rainfall. It was highest (1.88) in years classified as rainy, medium (1.62) in years classified as normal, and lowest (1.24) in dry years. A total of 404 white storks were ringed, 110 of which were observed a total of 308 times (2.8 + 2.8 times per bird, range 1–12, all year data pooled). Recovery data show that with one exception, all ringed birds were recorded at different habitats of S Spain throughout the year. Remarkably, none was observed at traditional wintering quarters, south of the Sahara in Africa. Juveniles remained in the area (from July to October) soon after leaving our colony, and virtually all of them disappeared from November to January (their first winter) but were recorded again during their first breeding season. On the contrary, adults were repeatedly recorded at different sites in Cádiz, Sevilla and Huelva all year round. These birds showed a strong philopatry as some of them were recorded as breeders in our colony, up to 11 years after ringing. Our data emphasize the importance of both refuse damp and wetland areas for the species, especially in winter, and a shift in the timing of the reproductive season as birds were recorded from November to July

Full Text Available In this last part of the series of articles concerning the migration of the white storks (Ciconia ciconia in the Doamnei River hydrographical basin, the authors make some considerations regarding the overflown areas and habitats, the aerial activity dependingon the lapse of time and the intra- and inter-specific bonds. The most individuals were observed in the hilly area, flying principally over the settlements and forests. April was the most intense month regarding the migration, the maximum of the aerial activity being between 16:00 and 17:00 for the observations per hour and between 17:00 and 18:00 for the observed individuals per hour. The birds avoided to fly on bad weather conditions and they preferred to use the soaring and gliding flights. Usually, they did not emit any sound.Rarely, the storks were temporarily accompanied in flight by other birds (Pernis apivorus, Accipiter nisus and Falco tinnunculus.

Herpesvirus isolations from peripheral white blood cells of 253 White Storks (Ciconia ciconia) were obtained during a long-term study (1983 to 2001). The storks lived for a few months to 20 years at four rehabilitation centres. Isolates were obtained from 83 of 253 storks. This herpesvirus is indigenous for storks and unrelated to any other avian herpesvirus. Significantly more herpesvirus isolates were obtained during spring than in autumn samplings. The intervals between the first and last virus isolation ranged from 1 to 15 years. Herpesvirus isolates were simultaneously obtained from white blood cells and from pharyngeal swabs of four of 34 storks but not from cloacal swabs. Neutralizing antibodies to stork herpesvirus were detected in 178 of 191 examined blood plasma samples. Neutralizing antibodies against stork herpesvirus did not correlate with herpesvirus viraemia. The results further substantiate the persistence of herpesvirus in White Storks and underline the previously unrecorded long periods of virus and antibody presence. Virulent avian paramyxovirus type 1 (APMV-1; Newcastle disease virus) was isolated from white blood cells during 1992 and 1993 from four healthy migrating storks, and possessed virulence markers on the cleavage site of the H and F genes. These properties resemble the NE type of APMV-1. Haemagglutination inhibition antibodies against APMV-1 were detected in 16 of 191 blood plasma samples. Avian influenza A virus was not isolated and antibodies against subtypes H5 and H7 were not detected.

In the Aznalcóllar mining accident (April 1998), nearly six million cubic meters of toxic wastes were spilled in the surroundings of the Doñana National Park (southwestern Spain). The present study focused on the likely effects of metal pollution on the immune system of nestling white storks (Ciconia ciconia) and black kites (Milvus migrans) sampled in the nearby area. Using the phytohaemagglutinin skin test, we examined cell-mediated immune response (CMI) in relation to Pb, Zn, Cu, Cd, and As concentrations in blood of 281 nestling white storks and of 89 black kites. The former species was monitored along a four-year period (1999, 2001-2003), while black kites were sampled in 1999. Overall, average levels of heavy metals and As were relatively low when compared to those reported for birds in metal-polluted areas. Copper showed a negative effect on CMI in both species, although the relationship was significant only for white storks in 2002. We found no evidence that environmental exposure to Pb, Zn, As, and Cd had any effect on nestlings' CMI. Interannual consistency is revealed as an important factor, supporting the need of long-term studies when assessing the immunotoxic effects of metal exposure in the wild.

Post-Mating Sexual Behaviors of Oriental Storks (Ciconia boyciana) in Captivity.

Parental behaviors that vary by sex and breeding stage facilitate the survival of offspring in birds. Females invest in reproducing according to the level of direct and/or indirect benefits provided by males. Males face trade-offs from defending territories or nests, providing for the young, and seeking additional mating opportunities. We examined whether post-mating sexual behaviors such as courtship display and nest-building were associated with reproductive investments made by males and females in the current study. The oriental stork (Ciconia boyciana) is known as a solitary breeder that nests in tall trees and provides biparental care with long post-hatching development. We filmed parental behaviors in seven stork pairs in captivity for 655 hours (245 hours during nest-building, 218 hours during incubation, 328 hours during nestling, and 192 hours during the fledgling period). We found that paired mating behaviors such as synchronous allopreening and bill-clattering were highly skewed to the pre-incubation period. Males participated in nest-building more than females although both sexes shared similar parental care during the incubation and nestling period. Male nest-building was negatively correlated with male nest attentiveness only during the nestling period. Our results suggest that male oriental storks with higher nest-building effort might spend more time taking precautions against conspecific intruders or nest predators near the nests with chicks while the females were attending the nests in the form of biparental care.

Bird blood was tested for T. gondii antibodies by an indirect fluorescent antibody test. T. gondii antibodies were detected from 5.8% of 205 analysed white stork chicks and 13.6% of 44 analysed adult storks in the zoo. Because toxoplasmosis is one of the more common parasitic zoonoses worldwide, we briefly discuss the potential epidemiological importance of stork toxoplasmosis to humans.

House sparrows benefit from the conservation of white storks

Kosicki, Jakub Z.; Sparks, Tim H.; Tryjanowski, Piotr

2007-05-01

As with many farmland bird species, the house sparrow Passer domesticus is declining in Europe, mainly due to intensification of agriculture reducing nest sites and food supplies. During 2002-2005, we studied the population size and nest site characteristics of house sparrows breeding within white stork Ciconia ciconia nests in a large area of agricultural landscape within western Poland. To explain sparrow density within stork nests, we examined characteristics of white stork nests (position, age, productivity) and the farm type around the nest. House sparrow density was greatest in the longest established (and hence larger) white stork nests located on traditionally managed farms. Two recent changes appear to have adverse effects on house sparrows. The first is the intensification of farming and the second is active management of white stork nests on electric poles to reduce nest size and thus avoid both disruption to the electrical supply and electrocution of white storks. Because the white stork has such a high profile in Poland, there are numerous schemes to conserve and enhance this species. In conclusion, we clearly show that protecting one species can have valuable, although unplanned, benefits to another species of conservation interest, the house sparrow.

Sex differences in the foraging ecology of monomorphic species are poorly understood, due to problems with gender identification in field studies. In the current study, we used experimental conditions to investigate the food preferences of the white stork Ciconia ciconia, an opportunistic species in terms of food, but characterised by a low level of sexual dimorphism. During a 10-day experiment, 29 individuals (20 females and 9 males) were studied by means of a `cafeteria test' in which the storks' diet consisted of mammals, birds, fish, amphibians, insects and earthworms. The storks preferred food characterised by high calorific and protein values such as mammals, birds and fish. Sexes differed strongly in their preferences; males preferred mammals, whereas females preferred birds. Moreover, females consumed insects and earthworms less often than males. Interestingly, males spent significantly less time foraging than females. We have demonstrated that the white stork exhibits clear sexual differences in food preferences which are mostly attributable to differences in parental duties, physiology and anatomy.

In 1998, the Aznalcollar mine tailings dyke in southwestern Spain broke, flooding the Agrio-Guadiamar river system with acid tailings up to the borders of one of the largest breeding colonies of white storks in the western Palearctic, Dehesa de Abajo. Over the following years, a high proportion of nestlings developed leg defects not seen before the spill, prompting this study. Nestlings with deformed legs had significantly lower plasma phosphorous (P) and higher Ca:P ratios than non-deformed cohorts in the first two years, but in the third year, when more, younger birds were studied, plasma P ranged from much higher to much lower in the affected colony compared with reference birds. Coefficients of variation for phosphorous were 19% and 60%, in reference and contaminated colonies, respectively. Storks from the contaminated colony were unable to control P levels and Ca:P ratios within the narrow limits necessary for normal bone development. - Since a large mine tailings spill near a stork colony in southwestern Spain, nestlings had leg deformities and could not control serum phosphorous levels and Ca:P ratios

Full Text Available The diet of non-breeding White Storks was studied by pellet analysis and included mainly insects (99.9%, n=28947 with a predominance of grasshoppers (Orthoptera, 76.1%, and beetles (Coleoptera, 26.1%. The bush crickets Decticus albifrons/verrucivorus were the most numerous prey (29.9% by items, occurring in almost all pellets (98% occurrence in pellets, n=147 and predominating in half of them (49.7%. The grasshopper associations in the pellets specify foraging mainly in mesophytic grasslands that usually replace abandoned fields and overgrown pastures with a low level of grazing. The xerophytic grass-shrubby habitats, not rare on stony terrains, were of less importance, providing around 20% by prey. The typical aquatic inhabitants and the use of carrion around villages were exceptions in the study diet. The number of innutritious materials in the pellets rose when the White Storks hunted on nippy and agile grasshoppers and decreased when the main pray was slower beetles taken from the ground. The roosting of non-breeding White Storks disappeared when their preferred feeding habitats were ploughed up in the following years.

Full Text Available In a period of 30 years (1984-2013, 1,535 White Stork pulli were ringed on nest and 1,226 nests examined in NE Slovenia. The ringing was implemented in the regions of Dravsko polje, Slovenske gorice and Pomurje. In each season, from 9 to 85 nests were examined, the great majority of them built on overhead powerline pylons. On average, 51.16 pulli or 16.66% were ringed and 40.86 or 18.91% nests visited compared to the census of fledged pulli and inventoried nests in 1999 in NE Slovenia. A total of 71 finds or 4.6% were registered and 37 rings or 52% finds read. There were 26 (36.62% local recoveries, while in foreign countries 34 (47.88% recoveries of Slovenian-ringed storks were made. Two of our recoveries were registered abroad prior to 1984. There were 11 (15.49% foreign recoveries. Local recoveries (n = 26 indicate breeding relationship (mixing between the eastern and southern Slovenian breeding populations. The longest distance of breeding was 115 km in a beeline, the shortest 62 km (n = 4. Other 12 local recoveries at 1 to 38 km from the place of hatching concerns the native NE breeding area. Young sexually mature storks search for new breeding sites only in their fourth year of age. No ringed stork returned to the native nest as a young breeder. The oldest was 14 years old. Some of them breed in the wider area of the Pannonian Plain outside Slovenia, e.g. 3 in Austria, 2 in Serbia and 1 in Croatia. One of them bred in Slovakia 463 km away. In view of the presented recoveries it has been ascertained that the storks from NE Slovenia migrate across the Pannonian Plain, the Balkans and Asia Minor, down to the South African Republic of 8,923 km in a beeline (4 recoveries, using the eastern migration route. The western migration route was not ascertained. The majority of recoveries originated from the autumn migration period, with only one recovery known from the spring migration period. No less than 23 ringed storks, particularly young ones

Impact of supplementary feeding on reproductive success of white storks.

Directory of Open Access Journals (Sweden)

Roland Hilgartner

Full Text Available European white stork (Ciconia ciconia populations have been object to several conservation measures such as reintroduction programs, habitat improvement or supplementary feeding in the last decades. Although recent white stork censuses revealed an upward trend of most of the western populations, evaluations of the relative importance of certain conservation measures are still scarce or even lacking. In our study we analyzed the effect of supplementary feeding on the reproductive success of white storks in conjunction with other factors such as weather or nest site characteristics. We present data of 569 breeding events at 80 different nest sites located in variable distances to an artificial feeding site at Affenberg Salem (south-western Germany collected from 1990-2012. A multilevel Poisson regression revealed that in our study population (1 reproductive success was negatively affected by monthly precipitation in April, May and June, (2 pairs breeding on power poles had a lower reproductive success than pairs breeding on platforms or trees and (3 reproductive success was significantly higher in pairs breeding in close distance to the feeding site. The number of fledglings per nest decreased by 8% per kilometer distance to the feeding site. Our data suggest that supplementary feeding increases fledgling populations which may be a tool to attenuate population losses caused by factors such as habitat deterioration or unfavorable conditions in wintering habitats.

Cadmium, lead, mercury, selenium, iron, zinc and arsenic levels were measured in blood samples from 59 free-ranging white stork nestlings from colonies located in three different environmental conditions in Western Spain. The reference colony was situated in "Llanos de Cáceres y Sierra de Fuentes", an Area of Special Interest for Bird Protection. A second colony was located close to (4.9 km) an urban landfill and a third one was close to both an intensive agricultural area and an urban landfill (1.5 km). Blood samples were diluted and elemental analysis was performed using inductively coupled plasma mass spectrometer. In all cases, the essential metals zinc and iron were found at the highest mean concentrations followed by lead > selenium > mercury > arsenic > cadmium. Regarding toxic metals, the highest concentrations were found for lead (ranging from 23.27 to 146.4 µg/L) although in all cases the concentrations were lower than those considered to cause subclinical effects. The metals levels detected in the chick's blood were not related to the previously reported levels in the soil next to the colonies, which may indicate that landfills are the main source of metals in white stork nestlings. The present data showed that metal levels in white stork chicks may be influenced by the use of landfills as feeding areas by the parents. However, more studies on the metal content in the feed of white stork and the influence of the distance to the landfill are necessary to establish the causality of these findings.

2016-04-01

Full Text Available This article presents data on the diet of the White-Tailed Eagle (Haliaeetus albicilla collected during breeding seasons of 2006–2015 in the Polesski State Radiation-Ecological Reserve. The data included 127 records of prey remains belonging to 27 species of vertebrates collected in and under the nests. We discovered that the diet of the White-Tailed Eagle mainly consists of vertebrates of three classes: fishes (Pisces 48.1 %, birds (Aves 41.7 % and mammals (Mammalia 10.2 %. At the present, the main prey species in the diet of the White-Tailed Eagle in the breeding season are: Bream (Abramis brama – 22.0 %, Black Stork (Ciconia nigra – 12.6 %, Northern Pike (Esox lucius – 10.2 %, Wild Boar (Sus scrofa – 7.1 %, White Stork (Ciconia ciconia – 6.3 %, Mallard (Anas platyrhynchos – 5.5 % and Eurasian Coot (Fulica atra – 5.5 %. Together these species makes up 69.2 % or 2/3 of the diet of this raptor. We also established that cannibalism is a character feature of the local population of White-Tailed Eagle, and its proportion is 2.4 %.

Changes in the number of nesting pairs and breeding success of theWhite Stork Ciconia ciconia in a large city and a neighbouring rural area in South-West Poland

Full Text Available During the years 1994–2009, the number of White Stork pairs breeding in the city of Wrocław (293 km2 fluctuated between 5 pairs in 1999 and 19 pairs 2004. Most nests were clumped in two sites in the Odra river valley. Two nests were located only cca. 1 km from the city hall. The fluctuations in numbers can be linked to the availability of feeding grounds and weather. In years when grass was mowed in the Odra valley, the number of White Storks was higher than in years when the grass was left unattended. Overall, the mean number of fledglings per successful pair during the years 1995–2009 was slightly higher in the rural than in the urban area. Contrary to expectation, the mean number of fledglings per successful pair was the highest in the year of highest population density. In two rural counties adjacent to Wrocław, the number of breeding pairs was similar to that in the city in 1994/95 (15 vs. 13 pairs. However, in 2004 the number of breeding pairs in the city almost doubled compared to that in the neighboring counties (10 vs. 19 pairs. After a sharp decline between 2004 and 2008, populations in both areas were similar in 2009 (5 vs. 4 pairs, but much lower than in 1994–1995. Wrocław is probably the only large city (>100,000 people in Poland, where the White Stork has developed a sizeable, although fluctuating, breeding population. One of the most powerful role the city-nesting White Storks may play is their ability to engage directly citizens with nature and facilitate in that way environmental education and awareness.

Power lines are increasingly widespread across many regions of the planet. Although these linear infrastructures are known for their negative impacts on bird populations, through collision and electrocution, some species take advantage of electricity pylons for nesting. In this case, estimation of the net impact of these infrastructures at the population level requires an assessment of trade-offs between positive and negative impacts. We compiled historical information (1958-2014) of the Portuguese white stork Ciconia ciconia population to analyze long-term changes in numbers, distribution range and use of nesting structures. White stork population size increased 660% up to 12000 breeding pairs between 1984 and 2014. In the same period, the proportion of nests on electricity pylons increased from 1% to 25%, likely facilitated by the 60% increase in the length of the very high tension power line grid (holding the majority of the nests) in the stork’s distribution range. No differences in breeding success were registered for storks nesting on electricity pylons versus other structures, but a high risk of mortality by collision and electrocution with power lines was estimated. We discuss the implications of this behavioral change, and of the management responses by power line companies, both for stork populations and for managers.

Impact of Environmental Changes on Migratory Bird Survival

Sabine Stöcker-Segre

2014-01-01

Full Text Available We present a mathematical model that studies and simulates the interconnection between energetic and ecological aspects of bird migration. By comparing model predictions with experimental data, we show that it can be used to assess the impact of changing environmental conditions in breeding, wintering, and stop-over sites on migratory success. We relate in particular to the European white stork (Ciconia ciconia and its Eastern migration route and discuss questions concerning the timing, stopover, and feeding behavior en route. Opinions concerning the importance of resource availability and resource quality en route are divided. Whereas some studies have shown that storks gain weight in the wintering site, but almost do not feed en route, others stress the importance of the quality of stop-over locations. We address these questions and simulate the development of stork populations for changing environmental conditions. We demonstrate that resource availability and competition for breeding sites are crucial factors determining the timing of spring migration and the length of stop-over periods. Analyzing the robustness of migration strategies with respect to changing environmental conditions, we show that birds will shorten their stay in stop-over places of poor resource availability rather than prolonging it in the attempt to gain time for accumulating fat reserves.

Testing the additive versus the compensatory hypothesis of mortality from ring recovery data using a random effects model

Directory of Open Access Journals (Sweden)

Schaub, M.

2004-06-01

Full Text Available The interaction of an additional source of mortality with the underlying “natural” one strongly affects population dynamics. We propose an alternative way to test between two forms of interaction, total additivity and compensation. In contrast to existing approaches, only ring-recovery data where the cause of death of each recovered individual is known are needed. Cause-specific mortality proportions are estimated based on a multistate capture-recapture model. The hypotheses are tested by inspecting the correlation between the cause-specific mortality proportions. A variance decomposition is performed to obtain a proper estimate of the true process correlation. The estimation of the cause-specific mortality proportions is the most critical part of the approach. It works well if at least one of the two mortality rates varies across time and the two recovery rates are constant across time. We illustrate this methodology by a case study of White Storks Ciconia ciconia where we tested whether mortality induced by power line collision is additive to other forms of mortality.

Excessive use of plastics in daily life and the inappropriate disposal of plastic products are severely affecting wildlife species in both coastal and aquatic environments. Birds are top-predators, exposed to all threats affecting their environments, making them ideal sentinel organisms for monitoring ecosystems change. We set a baseline assessment of the prevalence of marine plastic litter affecting multi-species populations of aquatic birds in southern Portugal. By examining 160 stomach contents from 8 species of aquatic birds, we show that 22.5% were affected by plastic debris. Plastic was found in Ciconia ciconia, Larus fuscus and L. michahellis. Ciconia ciconia ingested the highest amount (number of items and total mass) of plastic debris. Polydimethylsiloxane (PDMS, silicones) was the most abundant polymer and was recorded only in C. ciconia. Plastic ingestion baseline data are of crucial importance to evaluate changes through time and among regions and to define management and conservation strategies. Copyright © 2017 Elsevier Ltd.

2017-10-01

Full Text Available Aquatic wild birds have been intensively studied to better understand their role in avian influenza virus (AIV maintenance and spread. To date, AIV surveillance has primarily focused on natural aquatic environments where different bird species aggregate and viral survival is enhanced. However, artificial habitats such as landfills are attracting substantial numbers of wild birds, AIV reservoir species included. The use of landfills as a predictable food source has significantly influenced population size, migratory traits, and feeding behavior of white storks (Ciconia ciconia and black-headed gulls (Chroicocephalus ridibundus among others. Considering the proximity of landfills to urban settlements and frequently poultry-farms, targeted monitoring of AIV in bird species that forage at landfills but are known to also frequent urban and agricultural habitats could be a useful means for monitoring of AIV, especially during periods of bird aggregation. During the wintering season 2014–2015, the prevalence of AIV in five avian species at two landfills in South-Central Spain was explored by rRT-PCR and species related temporal variation in AIV prevalence determined. We collected and tested 1,186 fresh fecal samples from white storks (N = 689, cattle egrets (Bubulcus ibis, N = 116 and mixed flocks of gulls (N = 381 as well as cloacal and oral swabs from five birds found dead. Seven samples contained AIV, five from gulls and one each from a stork and a cattle egret. Overall, AIV prevalence was 0.60%. No significant temporal variation was observed in AIV prevalence. Prevalence differed significantly among the sampled taxonomic groups, being highest in gulls (1.31%. H16N3 subtype was detected from a cattle egret and H11N9 subtype from a white stork, whereas gulls harbored both subtypes in addition to H11N3 subtype. H16 subtype detection in a cattle egret evidences its host range may not be restricted to gulls. Our results indicate that wild

Full Text Available In 2016, data on 176 bird species were gathered during bird ringing activities in Slovenia. A total of 65,711 birds of 165 different species were ringed. Furthermore, 148 recoveries of birds ringed in Slovenia and found abroad, 245 foreign recoveries in Slovenia and 1840 local recoveries were made. The most frequently ringed species was the Blackcap Sylvia atricapilla. Among the ringed nestlings, Great Tits Parus major, Tree Sparrows Passer montanus and White Storks Ciconia ciconia predominated. Considering recoveries of birds ringed or found abroad, the most frequent were finds based on colour rings, especially of Black-headed Gulls Chroicocephalus ridibundus, Mute Swans Cygnus olor and Common Terns Sterna hirundo. As far as local recoveries are concerned, most data were collected for Great Tit and Siskin Spinus spinus. Among rare species, two Yellow-browed Warblers Phylloscopus inornatus were ringed, one Paddyfield Warbler Acrocephalus agricola, one Little Emberiza pusilla and one Black-headed Bunting Emberiza melanocephala, the latter as a singing male, which probably also bred in 2016. The catch frequency of the Yellow-browed Warblers has indeed been increasing in Slovenia in the last 25 years, but this is still a rare and irregular vagrant on autumn migration.

Characterization of cholinesterases in plasma of three Portuguese native bird species: application to biomonitoring.

Directory of Open Access Journals (Sweden)

Cátia S A Santos

Full Text Available Over the last decades the inhibition of plasma cholinesterase (ChE activity has been widely used as a biomarker to diagnose organophosphate and carbamate exposure. Plasma ChE activity is a useful and non-invasive method to monitor bird exposure to anticholinesterase compounds; nonetheless several studies had shown that the ChE form(s present in avian plasma may vary greatly among species. In order to support further biomonitoring studies and provide reference data for wildlife risk-assessment, plasma cholinesterase of the northern gannet (Morus bassanus, the white stork (Ciconia ciconia and the grey heron (Ardea cinerea were characterized using three substrates (acetylthiocholine iodide, propionylthiocholine iodide, and S-butyrylthiocholine iodide and three ChE inhibitors (eserine sulphate, BW284C51, and iso-OMPA. Additionally, the range of ChE activity that may be considered as basal levels for non-exposed individuals was determined. The results suggest that in the plasma of the three species studied the main cholinesterase form present is butyrylcholinesterase (BChE. Plasma BChE activity in non-exposed individuals was 0.48±0.11 SD U/ml, 0.39±0.12 SD U/ml, 0.15±0.04 SD U/ml in the northern gannet, white stork and grey heron, respectively. These results are crucial for the further use of plasma BChE activity in these bird species as a contamination bioindicator of anti-cholinesterase agents in both wetland and marine environments. Our findings also underscore the importance of plasma ChE characterization before its use as a biomarker in biomonitoring studies with birds.

Full Text Available 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.

Population trends of Goričko agricultural landscape birds

Directory of Open Access Journals (Sweden)

Denac Katarina

2017-12-01

Full Text Available Due to numerous bird surveys in the past 20 years, the avifauna of Goričko is relatively well known. For some species, the very first national ecological researches were conducted in this area. The article summarizes all bird surveys so far. It presents population trends of farmland species which is one of the most threatened bird groups in Europe. Most of the qualifying species of this habitat that are protected within the Natura 2000 network have suffered a decline at Goričko, specifically Quail Coturnix coturnix, Scops Owl Otus scops, Hoopoe Upupa epops, Woodlark Lullula arborea and White Stork Ciconia ciconia. The number of breeding pairs of the latter has not changed, but its fecundity has decreased. Furthermore, populations of other farmland bird species have decreased, for example Skylark Alauda arvensis, Stonechat Saxicola rubicola, Serin Serinus serinus and Common Linnet Linaria cannabina, as well as butterfly populations and tracts of grassland habitat types. National agricultural and nature conservation policies are evidently inefficient in protecting the biodiversity of Goričko. The most probable cause for bird population decline is agricultural intensification, which manifests itself at Goričko as disappearance and intensification of meadows, land consolidation, degradation of traditional orchards and use of pesticides. As a result of land consolidation hedges, uncultivated strips between fields, individual trees and bushes and minority habitat types are disappearing, whereas the surface of arable fields is increasing. Nature conservation measures performed by the Public Institute Goričko Nature Park with the support of DOPPS – BirdLife Slovenia volunteers seem to be efficient, but are spatially and temporally constrained. For this reason, they cannot serve as a substitute for insufficient systemic financing which could be improved by substantive and financial reform of the agri-environmental scheme. Currently, a negligible

Highlights: • G4-STORK is a new, time-dependent, Monte Carlo code for reactor physics applications. • G4-STORK was built by adapting and expanding on the Geant4 Monte Carlo toolkit. • G4-STORK was designed to simulate short-term fluctuations in reactor cores. • G4-STORK is well suited for simulating sub- and supercritical assemblies. • G4-STORK was verified through comparisons with DRAGON and MCNP. - Abstract: In this paper we introduce G4-STORK (Geant4 STOchastic Reactor Kinetics), a new, time-dependent, Monte Carlo particle tracking code for reactor physics applications. G4-STORK was built by adapting and expanding on the Geant4 Monte Carlo toolkit. The toolkit provides the fundamental physics models and particle tracking algorithms that track each particle in space and time. It is a framework for further development (e.g. for projects such as G4-STORK). G4-STORK derives reactor physics parameters (e.g. k eff ) from the continuous evolution of a population of neutrons in space and time in the given simulation geometry. In this paper we detail the major additions to the Geant4 toolkit that were necessary to create G4-STORK. These include a renormalization process that maintains a manageable number of neutrons in the simulation even in very sub- or supercritical systems, scoring processes (e.g. recording fission locations, total neutrons produced and lost, etc.) that allow G4-STORK to calculate the reactor physics parameters, and dynamic simulation geometries that can change over the course of simulation to illicit reactor kinetics responses (e.g. fuel temperature reactivity feedback). The additions are verified through simple simulations and code-to-code comparisons with established reactor physics codes such as DRAGON and MCNP. Additionally, G4-STORK was developed to run a single simulation in parallel over many processors using MPI (Message Passing Interface) pipes

Fish mercury levels from some Carolina bays pose risk to wood stork. - Carolina bays are freshwater wetlands that serve as important feeding habitats for the endangered wood stork (Mycteria americana). Water levels in these bays fluctuate greatly and tend to be acidic and rich in dissolved organic carbon (DOC), factors that favor mercury (Hg) methylation and bioaccumulation in fish. To assess potential risks to wood storks consuming mercury contaminated fish in bays, we sampled fish from 10 bays on the Savannah River Site (SRS), South Carolina, an area with documented use by wood storks. Whole body mercury concentrations in 258 fishes of three species (Erimyzon sucetta, Acantharchus pomotis and Esox americanus) commonly consumed by wood storks were determined. Risk factors for nestlings and free-ranging adults were calculated using published no and lowest observable adverse effect concentration (NOAEC and LOAEC) values for birds. Fish from higher trophic levels and those from wetlands with relatively shallow maximum depths and fluctuating water levels were more likely to exceed NOAEC and LOAEC values. Calculation of exposure rates of nestling wood storks indicated they are at highest risk during the first 10 days of the nestling period. These calculations suggest that there is potential concern for wood storks foraging in relatively shallow bays with fluctuating water levels, even though there is no obvious local source of mercury to these wetlands

Full Text Available In 2014, 162 bird species were recorded during the bird ringing activities in Slovenia. Of 155 species, 62,275 birds were ringed, and 107 recoveries of birds ringed in Slovenia and found abroad, 148 foreign recoveries in Slovenia and 1395 local recoveries were recorded. The most frequently ringed species were Blackcap Sylvia atricapilla and Great Tit Parus major. As far as ringed nestlings are concerned, Great Tits and Barn Swalllows Hirundo rustica predominated. Considering the recoveries ringed of found birds abroad, the commonest were Black-headed Gulls Chroicocephalus ridibundus and Mute Swans Cygnus olor. The farthest recovery was a Barn Swallow Hirundo rustica found in the Democratic Republic of Congo (5171 km away. Among the more interesting finds was also the so far southernmost recovery of a Sand Martin Riparia riparia found in Israel. Let us also mention the first recovery of a Corncrake Crex crex, which bred and was ringed in 2013 at Planinsko polje (central Slovenia and was found in the 2014 breeding season in the Czech Republic. Among rare species, two Little Buntings Emberiza pusilla were caught and ringed. After nine years, the Roller Coracias garrulus bred again in Slovenia in 2014 and its nestlings were ringed. The paper also brings the description of the migration route of the first African migrant, the Black Stork Ciconia nigra, marked with a GPS/GSM telemetric device, which migrated across the Adriatic Sea, Sicily and Sahara to Nigeria.

Full Text Available Niemodlin countryside (c. 300 km2 is situated in the south-western part of Opole Silesia, SW Poland. Forests occupy c. 40%, arable grounds – 1/3, and meadows and pastures – 7%. There are 31 fish-ponds with a total diked surface of 663 ha. The paper presents results of field investigations carried out during the years 2002-2007 and an analysis of changes in the breeding avifauna over the last 56 years. During the years 2002-2007, 123 breeding and 11 probably breeding bird species were recorded in this area. During the years 1962-2007 151 species were recorded as breeding residents; and additional five species – as probably breeding resident. The following species were recorded as breeding for the first time in 1962-2007: Haliaeetus albicilla, Larus canus, Motacilla cinerea, Saxicola torquata, Locustella luscinioides, Ficedula albicollis, Corvus corax and Carpodacus erythrinus. In the same period the following species became extinct: Podiceps nigricollis, Anas clypeata, Milvus milvus, and Tringa glareola. The following species increaed in numbers in 1962-2007: Coturnix coturnix, Grus grus, Columba oenas, Apus apus, Dryocopus martius, Dendrocopos medius, Motacilla cinerea, Saxicola torquata and Corvus corax. In the same period, Tachybaptus ruficollis, Podiceps cristatus, Podiceps grisegena, Ciconia ciconia, Aythya nyroca, Perdix perdix, Gallinago gallinago, Larus ridibundus, Tyto alba, Alcedo atthis, Picus viridis, Riparia riparia and Corvus cornix decreased in numbers. The areas with the highest concentration of rare and endangered species are postulated to be protected as nature reserves, landscape parks and other spatial forms of nature conservation.

Kumasir lake is located next to towns of Donuklu and Fatih, nine km west of Kahramanmaras city center the region of east Mediterranean, Turkey This lake is of crucial importance from the point of native and immigrant birds. We located 17 birdspecies in this area during our observations carried out in the spring and autumn of 2005-2006. These were Ciconia ciconia L., Anas platyrhynchos L., Accipiter nisus L., Accipiter brevipes L., Fulica atra L., Columba palumbus L., Merops apiaster L., Upupa epops L., Alauda arvensis L., Motacilla flava L., Turdus merula L., Acrocephalus scirpaceus L., Regulus regulus L., Garrulus glandarius L., Corvus corax L., Fringilla coelebs L., Hirundo rustica L.. Among observed 17 species; 6 of them were immigrant and remaining 11 of them were native birds. Kumasir lake is surrounded by wetland of Amik and Gavur lake. Since it was greatly dried, it was transformed to farmland. Consequently the birds lost most of theirnests and settlements. However not taken in the care of environmental ethic values, the wastewaters of the villages drain to lake reservoir; herbicides and insecticides used for agriculture are polluting the water reeds have been burned, the lake's reeds are getting dry by the irrigation for the farmland. So, the wetland ecosystem is being affected negatively by these factors. On the other hand, the birds are exposed to illegal and unlawful hunting. For this reasons, this lake must be taken into a management regime of sustainable wetland (protection profiting balance) and used techniques of participation planning via the process of sustainable natural resources and planning.

Chaunocephalosis in a wild population of Asian open-billed storks in Thailand.

Poonswad, P; Chatikavanij, P; Thamavit, W

1992-07-01

The most common trematode collected from Asian open-billed storks (Anastomus oscitans) was Chaunocephalus ferox (80% prevalence). The trematode was paired in granulomas in the intestinal wall. Based on histological examination of these capsules, there was degeneration and necrosis of muscle cells in the tunica muscularis. Granulation tissue with hetrophil and lymphocyte infiltration appeared in the granulomas. Intestinal villi were shorter and wider in infected areas than in non-infected areas. Some intestinal glands were dilated. Storks with high intensity of C. ferox appeared ill. The death of storks infected with C. ferox may result from malnutrition due to the loss of absorptive function of the intestine and from the effect of granuloma formation which might interfere with the intestinal peristalsis.

Wood Storks of the Birdsville Colony and swamps of the Savannah River Site: General overview of research findings, 1983--1990

International Nuclear Information System (INIS)

Coulter, M.C.

1993-02-01

The population of Wood Storks (Mycteria americana) that breeds in the United States has decreased from an estimated 20,000 breeding pairs in 1930 to just under 5,000 pairs in 1980. Since 1980, the number has remained relatively stable, fluctuating between 3,500 and 5,500 breeding pairs. The decline prompted the US Fish and Wildlife Service (USFWS) to list the United States population of Wood Storks as endangered in 1984. When the US Department of Energy (USDOE) decided to restart L-Reactor on the Savannah River Site (SRS), there was concern that when the reactor was restarted, cooling water flowing into the Steel Creek Delta would raise the water level and the area would become too deep for foraging storks. The potential loss of this area to storks was important because storks had been observed foraging in the Steel Creek Delta. The USDOE began consultation with the USFWS in April, 1984, and the USDOE subsequently agreed to develop and maintain alternative foraging habitat to replace the potential loss. In order to design and manage the alternate foraging ponds as effectively as possible, it was necessary to understand aspects of the biology of the storks, the characteristics of their foraging sites and the patterns of their use of the SRSS. Results are described

Suspicious hybrids of painted storks and milky storks were found in a Malaysian zoo. Blood of these birds was sampled on FTA cards for DNA fingerprinting. Of 44 optimized primers, 6 produced diagnostic markers that could identify hybrids. The markers were based on simple, direct PCR-generated multilocus banding patterns that provided two sets of genetic data, one for each of the two stork species and another for the hybrids. It also revealed that large DNA fragments (3,000 bp) could be amplified from blood collected on FTA cards. When the results of each individual bird's DNA fingerprint were compared with plumage characters, the hybrids were found to express a range of intermediate phenotypic traits of the pure breeds with no dominant plumage characteristic from either parental species.

1993-05-01

Colonially-nesting birds often nest in coastal areas, along rivers, or near other bodies of water that also are potentially polluted from industrial, agricultural or urban development. The levels of heavy metals and selenium were examined in the feathers of young wood storks Mycteria americana nesting in Northeastern Florida and from adult and young storks nesting on the Tempisque River on the west coast of Costa Rica. There were no significant yearly differences among the chicks from Costa Rica. Concentration of mercury, cadmium, and lead were significantly higher in the chicks from Florida compared to those from Costa Rica. Adult wood storks at Costa Rica had significantly higher levels of lead, cadmium, selenium, and manganese than young from the same colony.

Genetic characterization of Neotropical Jabiru Storks: Insights for conservation

Jabiru Stork (Jabiru mycteria is listed under Appendix I of CITES and considered threatened in Central America. The first population genetic analysis of Jabiru Storks was carried out using mitochondrial DNA (mtDNA) control region sequences (520 bp) and five heterologous microsatellite loci. Samples were collected from the field (N = 49) and museum skins (N = 22) in Central (mainly Belize, Nicaragua and Costa Rica) and South America (Colombia, Venezuela, Peru and Brazil). A decline of mtDNA diversity was observed in comparisons between past (N = 20) and present (N = 40) samples collected in Central America and northern South America. Similar levels of microsatellite loci diversity were observed among contemporary samples. Lower levels of mtDNA variability were observed in samples from Central America and northern South America when compared to the Brazilian Pantanal region. Significant levels of genetic differentiation were found between contemporary locations sampled, whereas non-significant results were observed for historic samples. The non-geographic association of haplotypes observed at the cladograms and the recent divergence times estimated between locations are indicative of an evolutionary history of a large population size with limited population structure. Reconnection of populations via increased gene flow, particularly in Central America, is recommended if genetic structure and status are to be restored.

Full Text Available Cathaemasia hians is an obligate trematode parasite of Black storks that are on the List of protected birds in Europe. In the present study, adult trematodes were isolated from the Black stork post mortem and morphological study revealed C. hians species. In total, 10 worms were found in the oesophagus and the ventriculus of the bird. Histopathological examination of the tissue samples of oesophagus, proventriculus and ventriculus was performed on paraffin sections using a set of staining procedures. The sporadic lesions were seen in the tela submucosa of oesophagus containing connective tissue mast cells, eosinophils and heterophils and some foci were surrounded by the fibrous tissue. In addition, a few inflammatory nodules had larval-like material inside, probably being of the same species. There were no visible morphological alterations in the epithelial layer of lamina propria mucosae of proventriculus, rich in goblet cells as well as in the tela submucosa. Majority of trematodes were localized in the ventriculus, where the lamina propria mucosae was damaged or disrupted sporadically. In these sites, in the tela submucosa, a various food-originated inorganic/organic material and eggs of C. hians were deposited, stimulating a weak inflammatory response. Nodules containing larvae were not observed in any of ventriculus tissue layers. This study demonstrated, for the first time, infection with adults of C. hians trematode in the Black stork nesting in Slovakia. The presence of larvae and eggs in the tissues of the upper gastrointestinal tract of bird was associated with mild inflammatory response but feeding behaviour of adult worms in the ventriculus probably contributed to the enhanced susceptibility of the lamina propria mucosae to mechanical damage by inorganic material. Although larval stages have not yet been documented in the intermediate hosts in Slovakia, our report indicates that the life cycle of C. hians might occur in Central

Full Text Available In 2014, the International Waterbird Census (IWC was carried out in Slovenia on 18 and 19 Jan. Waterbirds were counted on all larger rivers, along the entire Slovenian Coastland and on most of the major standing waters in the country. During the census, in which 268 observers took part, 413 sections of the rivers and coastal sea with a total length of 1395.1 km and 226 other localities (178 standing waters and 48 streams were surveyed. Altogether, 45,346 waterbirds of 62 species were counted. This is the lowest number of waterbirds recorded after the 1997 and 1998 censuses. The greatest numbers of waterbirds were counted in the Drava count area, i.e. 20,217 individuals (44.6% of all waterbirds in Slovenia. By far the most numerous species was Mallard Anas platyrhynchos (43.0% of all waterbirds, followed by Black-headed Gull Chroicocephalus ridibundus (10.1% of all waterbirds, Coot Fulica atra (7.9% of all waterbirds, Yellow-legged Gull Larus michahellis (6.0% of all waterbirds and Cormorant Phalacrocorax carbo (4.6% of all waterbirds. The number of 1,000 counted individuals was also surpassed by Mute Swan Cygnus olor, Pochard Aythya ferina, Tufted Duck Ay. fuligula and Teal An. crecca. Among the rarer recorded species, the Black Stork Ciconia nigra (registered for the first time during the January Waterbird Censuses; only the second winter record in Slovenia, Cattle Egret Bubulcus ibis and Flamingo Phoenicopterus roseus (both registered only for the second time during the IWC should be given a special mention.

The Canadian Supercritical Water Reactor design was simulated using G4STORK. The results showed the expected trends but the determined Keff of 1.253±0.001 with a Coolant Void Reactivity (CVR) of -25mk differed greatly from the results achieved using MCNP of Keff=1.2914 and a CVR of -14mk. This discrepancy is partly due to the different data libraries used and the mixing of different temperature libraries in MCNP, but is also likely due to a difference in the physics methodology. Work is ongoing to further clarify reasons for discrepancies and improve the efficiency of the simulation. (author)

Aspergillus fumigatus is a common pathogen in poultry and captive wild birds and an emerging opportunistic fungal pathogen in immunocompromised humans. Although invasive aspergillosis is frequently reported in free-ranging wild birds, the incidence and epidemiology of the disease in a natural setting is unknown. We recently reported endemic outbreaks of invasive aspergillosis at white stork nesting sites close to human habitation in Germany with significant subsequent breeding losses. Therefore, we hypothesized that A. fumigatus strains with higher virulence in birds may have evolved in this environment and performed the first epidemiological analysis of invasive aspergillosis in free-ranging wild birds. Sixty-one clinical and environmental A. fumigatus isolates from six affected nesting sites were genotyped by microsatellite analysis using the STRAf-assay. The isolates showed a remarkable high genomic diversity and, contrary to the initial hypothesis, clinical and environmental isolates did not cluster significantly. Interestingly, storks were infected with two to four different genotypes and in most cases both mating types MAT-1.1 and MAT-1.2 were present within the same specimen. The majority of selected clinical and environmental strains exhibited similar virulence in an in vivo infection model using embryonated chicken eggs. Noteworthy, virulence was not associated with one distinct fungal mating type. These results further support the assumption that the majority of A. fumigatus strains have the potential to cause disease in susceptible hosts. In white storks, immaturity of the immune system during the first three weeks of age may enhance susceptibility to invasive aspergillosis. Copyright © 2010 Elsevier B.V. All rights reserved.

Full Text Available Biotelemetry is increasingly used to study animal movement at high spatial and temporal resolution and guide conservation and resource management. Yet, limited sample sizes and variation in space and habitat use across regions and life stages may compromise robustness of behavioral analyses and subsequent conservation plans. Here, we assessed variation in (i home range sizes, (ii home range selection, and (iii fine-scale resource selection of white storks across breeding status and regions and test model transferability. Three study areas were chosen within the Central German breeding grounds ranging from agricultural to fluvial and marshland. We monitored GPS-locations of 62 adult white storks equipped with solar-charged GPS/3D-acceleration (ACC transmitters in 2013–2014. Home range sizes were estimated using minimum convex polygons. Generalized linear mixed models were used to assess home range selection and fine-scale resource selection by relating the home ranges and foraging sites to Corine habitat variables and normalized difference vegetation index in a presence/pseudo-absence design. We found strong variation in home range sizes across breeding stages with significantly larger home ranges in non-breeding compared to breeding white storks, but no variation between regions. Home range selection models had high explanatory power and well predicted overall density of Central German white stork breeding pairs. Also, they showed good transferability across regions and breeding status although variable importance varied considerably. Fine-scale resource selection models showed low explanatory power. Resource preferences differed both across breeding status and across regions, and model transferability was poor. Our results indicate that habitat selection of wild animals may vary considerably within and between populations, and is highly scale dependent. Thereby, home range scale analyses show higher robustness whereas fine-scale resource

Full Text Available The explosion of available data has created much excitement among marketing practitioners about their ability to better understand the impact of marketing investments. Big data allows for detecting patterns and often it seems plausible to interpret them as causal. While it is quite obvious that storks do not bring babies, marketing relationships are usually less clear. Apparent “causalities” often fail to hold up under examination. If marketers want to be sure not to walk into a causality trap, they need to conduct field experiments to detect true causal relationships. In the present digital environment, experiments are easier than ever to execute. However, they need to be prepared and interpreted with great care in order to deliver meaningful and genuinely causal results that help improve marketing decisions.

Exposure of the endangered Milky stork population to cadmium and lead via food and water intake in Kuala Gula Bird Sanctuary, Perak, Malaysia

Directory of Open Access Journals (Sweden)

Faid Rahman

Full Text Available The Milky stork is listed as an endangered species endemic to the Southeast Asia region. In Malaysia, the population is currently being reintroduced back into the wild. However, the increase of anthropogenic activity throughout the coastal area might expose the population to hazardous chemicals such as heavy metals. This study highlights the contamination of cadmium (Cd and lead (Pb in the Milky stork’s diet. Additionally, this is the first time an integrated exposure model being used to assess heavy metal exposure risk to the population. Lead level (5.5–7.98 mg kg−1 in particular was relatively high compared to Cd (0.08–0.33 mg kg−1. This was probably related to the different niches occupied by the species in the aquatic environment. The results further show that the predicted exposure doses (through intake of both food and water for all metals are much lower than the Tolerable Daily Intake (TDI values. The total exposure dose for Cd was 0.11 mg kg−1 d−1 with TDI value of 0.54 mg kg−1 d−1 while Pb total exposure dose was 0.31 mg kg−1 d−1 with TDI value of 0.64 mg kg−1 d−1. Several possible factors that could lead to the observed pattern were discussed. In conclusion, there is an urgent need to improve the current habitat quality to protect the endangered species. The authors also emphasized on the protection of remaining Milky stork’s habitats i.e. mudflats and mangroves and the creation of buffer zone to mitigate the negative impacts that may arise from pollution activity.

Sedentary organisms that are at top trophic levels allow inference about the level of local mercury contamination. We evaluated mercury contamination in feather tissue of nestling Wood Storks (Mycteria americana), sampled in different parts of the Brazilian Pantanal that were variably polluted by mercury releases from gold mining activities. Levels of mercury in feathers sampled in seven breeding colonies were determined by atomic absorption spectroscopy, and the mean value of mercury concentration was 0.557 {mu}g/g, dry weight (n=124), range 0.024-4.423 {mu}g/g. From this total sample, 21 feathers that represent 30% of nestlings collected in Porto da Fazenda and Tucum colonies, in the northern region, ranged from 1.0 to 4.43 {mu}g/g, dry weight (median value=1.87 {mu}g/g). We found significant differences among regions (H=57.342; p=0<0.05). Results suggest that permanently flooded areas, or along mainstream rivers are more contaminated by mercury than dry areas, regardless of the distance from the gold mining center, which is located in the northern Pantanal. Highest values found in nestlings feathers were similar to those found in feathers of adult birds and in tissues of adult mammals that are less sedentary and were captured in the same region of Pantanal. These findings indicate that mercury released has been biomagnified and it is present in high concentrations in tissues of top consumers. We suggest a program to monitor mercury availability in this ecosystem using sedentary life forms of top predators like Wood Storks or other piscivorous birds. - Highlights: Black-Right-Pointing-Pointer Sedentary stork nestlings were used for the first time to show local mercury contamination of Pantanal.

In continuation of an earlier study in which we reported the cross-amplification of Wood stork microsatellites on the DNA obtained from molted feathers of Painted stork (Mycteria leucocephala), here we investigated the nature of cross-amplified microsatellites and the effect of non-invasive samples on cross-amplification success. In a limited manner, we also addressed the genetic diversity and differentiation in a north Indian population of the Painted Stork examined over three nesting seasons. Among the nine cross-amplified loci, only 5 were polymorphic. Three and 6 loci exhibited low ( 80), respectively. For 36 of 145 samples most of the loci failed to amplify. For genetic diversity, only 3 loci could be used since others exhibited low amplification and linkage disequilibrium. Probability of identity (0.034) was not low enough to develop a confidence that the similar genotypes originate from the same individual. Forty-two unique genotypes were identified. In 3 loci, a low to moderate level of genetic diversity (mean He = 0.435) was reported. Non-significant Fst (0.003, P = 0.230), G'stH (0.005, P = 0.247) and Dest (0.003, P = 0.250) values indicate a lack of structuring in temporally distributed populations of Delhi Zoo. The limitations and uniqueness of this study are discussed.

Full Text Available The jabiru stork, Jabiru mycteria (Lichtenstein, 1819, a large, long-legged wading bird occurring in lowland wetlands from southern Mexico to northern Argentina, is considered endangered in a large portion of its distribution range. We conducted aerial surveys to estimate the number of jabiru active nests in the Brazilian Pantanal (140,000 km² in September of 1991-1993, 1998, 2000-2002, and 2004. Corrected densities of active nests were regressed against the annual hydrologic index (AHI, an index of flood extension in the Pantanal based on the water level of the Paraguay River. Annual nest density was a non-linear function of the AHI, modeled by the equation 6.5 · 10-8 · AHI1.99 (corrected r² = 0.72, n = 7. We applied this model to the AHI between 1900 and 2004. The results indicate that the number of jabiru nests may have varied from about 220 in 1971 to more than 23,000 in the nesting season of 1921, and the estimates for our study period (1991 to 2004 averaged about 12,400 nests. Our model indicates that the inter-annual variations in flooding extent can determine dramatic changes in the number of active jabiru nests. Since the jabiru stork responds negatively to drier conditions in the Pantanal, direct human-induced changes in the hydrological patterns, as well as the effects of global climate change, may strongly jeopardize the population in the region.

This qualitative study is based on institutional analysis as the methodological theoretical reference with the objective of analyzing researchers' implication during a research-intervention and the interferences caused by this analysis. The study involved researchers from courses in medicine, nursing, and dentistry at two universities and workers from a Regional Health Department in follow-up on the implementation of the Stork Network in São Paulo State, Brazil. The researchers worked together in the intervention and in analysis workshops, supported by an external institutional analysis. Two institutions stood out in the analysis: the research, established mainly with characteristics of neutrality, and management, with Taylorist characteristics. Differences between researchers and difficulties in identifying actions proper to network management and research were some of the interferences that were identified. The study concludes that implication analysis is a powerful tool for such studies.

Isolated neck-lifting procedure: isolated stork lift.

Science.gov (United States)

Barbarino, Sheila C; Wu, Allan Y; Morrow, David M

2013-04-01

Many patients desire cosmetic improvement of neck laxity when consulting with a plastic surgeon about their face. Neck laxity and loss of the cervicomental angle can be due to multiple components of aging such as skin quality/elasticity, loss of platysma muscle tone, and submental fat accumulation. Traditionally, the procedure of choice for patients with an aging lower face and neck is a cervicofacial rhytidectomy. However, occasionally, a patient wishes to have no other facial surgery than an improvement of their excessive skin of the anterior, lateral, and/or posterior neck. In other instances, a patient may present with having had a face/neck-lifting procedure that left objectionable vertical/diagonal lines at the lateral neck. In both these instances, a surgeon should consider an isolated stork lift (ISL) procedure. An ISL procedure avoids and/or corrects problematic vertical/diagonal lateral neck folds by "walking" the excess skin flaps around the posterior inferior occipital hairline bilaterally, bringing the flaps together at the lateral and posterior neck, which sometimes involves a midline posterior dart excision of the dog ear. A patient presenting with excessive skin of the neck (anterior, lateral, and/or posterior) and/or residual vertical/diagonal skin folds is an excellent candidate for the ISL. The ISL procedure was performed on 273 patients over a 2-year period at The Morrow Institute. Patients were included if they had excessive skin of the anterior, lateral, and/or posterior neck and/or diagonal/vertical lateral bands and did not desire a full face-lifting procedure. Patients were excluded from this study if they would not accept having longer hair in order to cover the scar along the posterior inferior occipital hairline or a midline T-flap skin closure scar at the base of the posterior midline neck. Under a combination of local anesthesia and IV sedation, a postauricular face-lift incision was made that was extended in a circumoccipital fashion

Using heronry birds to monitor urbanization impacts: a case study of painted stork Mycteria leucocephala nesting in the Delhi Zoo, India.

Urfi, Abdul Jamil

2010-03-01

Although urbanization is a frequently cited cause of biodiversity loss (Czech and Krausman 1997) our understanding about urban ecology is severely limited (Marzluff et al. 2001). Birds are popular bio-indicators of environmental change because they are ecologically versatile, their populations as well as select fitness parameters can be conveniently monitored, often with the voluntary involvement of local nature enthusiasts across large geographical scales, and their presence/absence in a particular area is consequential (Bibby et al. 1992; Urfi 2004). In India, while several studies have focused on changes in bird populations and distributions in natural habitats (Urfi et al. 2005), very few have actually attempted to study either the impacts of urbanization on birds or how different species have adjusted to environmental change. However, many Indian cities offer foraging and nesting habitat for birds, especially colonial waterbirds such as stork, ibis, spoonbill, heron, egret, cormorant, and spoonbill. Some notable examples in this regard are Piele Gardens in Bhavnagar city (Parasharya and Naik 1990), Karanji Tank in Mysore (Jamgaonkar et al. 1994) and the National Zoological Park (hence forth Delhi Zoo) in India's capital city New Delhi (Urfi 1997). In this article, I focus on the opportunities for meaningful ecological research offered by the wild waterbirds nesting in the Delhi Zoo premises and discuss the significance for initiating novel, long term conservation monitoring programs, involving volunteers and bird watchers, to create data bases that will be useful for understanding urbanization and climate change impacts on biodiversity.

The 300 square mile Savannah River Plant (SRP) offers a variety of protected habitats for endangered species including the alligator (resident), red-cockaded woodpecker (resident), short-nose sturgeon (migratory), and wood stork (fish-forager). The most recent of these four species to be listed by the US Fish and Wildlife Service (US FWS) is the wood stork. It had been observed prior to 1983 as an infrequent forager in the SRP Savannah River Swamp which adjoins SRP on the south and southwest. In anticipation of its listing as an endangered species, DOE-SR requested in the spring of 1983 that the Savannah River Ecology Laboratory, University of Georgia, conduct field surveys and studies of the nearest colony of wood storks to SRP (the Birdsville colony in north-central Georgia). The objective of these studies was to determine potential effects of the flooding of the Steel Creek swamp area with cooling water from L-Reactor. L-Reactor, which is proposed for restart, has not been operated since 1968. The survey found that wood storks forage in the Steel Creek delta swamp area of the Savannah River at SRP. Based on the numbers of storks at various foraging locations, sites at SRP ranked higher than non-SRP sites during the pre-fledging phase of the colony. Cold flow testing of L-Reactor also demonstrated that foraging sites in the Steel Creek delta would be unavailable during L-Reactor operation because of increased water levels

Avihepadnaviruses have been documented previously in ducks, herons, geese, storks and cranes. Here, we describe the full genome of a new avihepadnavirus isolated from Psittacula krameri (ring-necked parrot) in Poland. The parrot hepatitis B virus (PHBV) genome (3042 bp) shares <76% sequence identity with other avihepadnavirus isolates and is phylogenetically most closely related to heron and stork hepatitis B viruses isolates. PHBV has a genome organization similar to that of other hepadnaviruses and contains ORFs for a preC/C, preS/S and polyprotein. Additionally, we identified an X-like ORF in the genome of PHBV.

Jan Szyszko

2011-05-01

Full Text Available Possibilities of the assessment of a landscape with the use of succession development stages, monitored with the value of the Mean Individual Biomass (MIB of carabid beetles and the occurrence of bird species are discussed on the basis of an example from Poland. Higher variability of the MIB value in space signifies a greater biodiversity. Apart from the variability of MIB, it is suggested to adopt the occurrence of the following animals as indicators, (in the order of importance, representing underlying valuable landscapes: black stork, lesser spotted eagle, white-tailed eagle, wolf, crane and white stork. The higher number of these species and their greater density indicate a higher value of the landscape for biodiversity and ecosystem services, especially carbon sequestration. All these indicators may be useful to assess measures for sustainable land use.

THE RELATIONSHIP BETWEEN MAXIMUM UNILATERAL SQUAT STRENGTH AND BALANCE IN YOUNG ADULT MEN AND WOMEN

Directory of Open Access Journals (Sweden)

Kevin McCurdy

2006-06-01

Full Text Available The purpose of this study was to determine the relationship between unilateral squat strength and measures of static balance to compare balance performance between the dominant and non-dominant leg. Seventeen apparently healthy men (mean mass 90.5 ± 20.9 kg and age 21.7 ± 1.8 yrs and 25 women (mean mass 62.2 ± 14.5 kg and age 21.9 ± 1.3 yrs completed the study. Weight bearing unilateral strength was measured with a 1RM modified unilateral squat on the dominant and non-dominant leg. The students completed the stork stand and wobble board tests to determine static balance on the dominant and non-dominant leg. Maximum time maintained in the stork stand position, on the ball of the foot with the uninvolved foot against the involved knee with hands on the hips, was recorded. Balance was measured with a 15 second wobble board test. No significant correlations were found between the measurements of unilateral balance and strength (r values ranged between -0.05 to 0.2 for the men and women. Time off balance was not significantly different between the subjects' dominant (men 1.1 ± 0.4 s; women 0.3 ± 0.1 s and non-dominant (men 0.9 ± 0.3 s; women 0.3 ± 0.1 s leg for the wobble board. Similar results were found for the time balanced during the stork stand test on the dominant (men 26.4 ± 6.3 s; women 24.1 ± 5.6 s and non-dominant (men 26.0 ± 5.7 s; women 21.3 ± 4.1 s leg. The data indicate that static balance and strength is unrelated in young adult men and women and gains made in one variable after training may not be associated with a change in performance of the other variable. These results also suggest that differences in static balance performance between legs can not be determined by leg dominance. Similar research is needed to compare contralateral leg balance in populations who participate in work or sport activities requiring repetitive asymmetrical use. A better understanding of contralateral balance performance will help

Balance, strength and power relationships may contain important information at various maturational stages to determine training priorities. The objective was to examine maturity-specific relationships of static/dynamic balance with strength and power measures in young male athletes. Soccer players (N = 130) aged 10-16 were assessed with the Stork and Y balance (YBT) tests. Strength/power measures included back extensor muscle strength, standing long jump (SLJ), countermovement jump (CMJ), and 3-hop jump tests. Associations between balance with strength/power variables were calculated according to peak-height-velocity (PHV). There were significant medium-large sized correlations between all balance measures with back extensor strength (r = .486-.791) and large associations with power (r = .511-.827). These correlation coefficients were significantly different between pre-PHV and circa PHV as well as pre-PHV and post-PHV with larger associations in the more mature groups. Irrespective of maturity-status, SLJ was the best strength/power predictor with the highest proportion of variance (12-47%) for balance (i.e., Stork eyes opened) and the YBT was the best balance predictor with the highest proportion of variance (43-78%) for all strength/power variables. The associations between balance and muscle strength/power measures in youth athletes that increase with maturity may imply transfer effects from balance to strength/power training and vice versa in youth athletes.

Visser, B. [Stork Product Eng., Amsterdam (Netherlands)

1996-09-01

To support the discussion on aeroelastic codes, a description of the code FLEXLAST was given and experiences within benchmarks and measurement programmes were summarized. The code FLEXLAST has been developed since 1982 at Stork Product Engineering (SPE). Since 1992 FLEXLAST has been used by Dutch industries for wind turbine and rotor design. Based on the comparison with measurements, it can be concluded that the main shortcomings of wind turbine modelling lie in the field of aerodynamics, wind field and wake modelling. (au)

A reappraisal of azhdarchid pterosaur functional morphology and paleoecology.

Science.gov (United States)

Witton, Mark P; Naish, Darren

2008-05-28

Azhdarchid pterosaurs were among the most widespread and successful of pterosaur clades, but their paleoecology remains controversial. Morphological features common to all azhdarchids include a long, shallow rostrum; elongate, cylindrical cervical vertebrae that formed a long and unusually inflexible neck; and proportionally short wings with an abbreviated fourth phalanx. While azhdarchids have been imagined as vulture-like scavengers, sediment probers, swimmers, waders, aerial predators, or stork-like generalists, most recent authors have regarded them as skim-feeders, trawling their lower jaws through water during flight and seizing aquatic prey from the water's surface. Although apparently widely accepted, the skim-feeding model lacks critical support from anatomy and functional morphology. Azhdarchids lack the many cranial specialisations exhibited by extant skim-feeding birds, most notably the laterally compressed lower jaw and shock absorbing apparatus required for this feeding style. Well-preserved azhdarchid skulls are rare, but their rostra and lower jaws appear to have been sub-triangular in cross-section, and thus dissimilar to those of skim-feeders and sediment probers. Taphonomic data indicates that azhdarchids predominately inhabited inland settings, and azhdarchid morphology indicates that they were poorly suited for all proposed lifestyles bar wading and terrestrial foraging. However, azhdarchid footprints show that their feet were relatively small, padded and slender, and thus not well suited for wading. We argue that azhdarchids were stork- or ground hornbill-like generalists, foraging in diverse environments for small animals and carrion. Proficient terrestrial abilities and a relatively inflexible neck are in agreement with this interpretation.

Hammami, R, Granacher, U, Makhlouf, I, Behm, DG, and Chaouachi, A. Sequencing effects of balance and plyometric training on physical performance in youth soccer athletes. J Strength Cond Res 30(12): 3278-3289, 2016-Balance training may have a preconditioning effect on subsequent power training with youth. There are no studies examining whether the sequencing of balance and plyometric training has additional training benefits. The objective was to examine the effect of sequencing balance and plyometric training on the performance of 12- to 13-year-old athletes. Twenty-four young elite soccer players trained twice per week for 8 weeks either with an initial 4 weeks of balance training followed by 4 weeks of plyometric training (BPT) or 4 weeks of plyometric training proceeded by 4 weeks of balance training (PBT). Testing was conducted pre- and posttraining and included medicine ball throw; horizontal and vertical jumps; reactive strength; leg stiffness; agility; 10-, 20-, and 30-m sprints; Standing Stork balance test; and Y-Balance test. Results indicated that BPT provided significantly greater improvements with reactive strength index, absolute and relative leg stiffness, triple hop test, and a trend for the Y-Balance test (p = 0.054) compared with PBT. Although all other measures had similar changes for both groups, the average relative improvement for the BPT was 22.4% (d = 1.5) vs. 15.0% (d = 1.1) for the PBT. BPT effect sizes were greater with 8 of 13 measures. In conclusion, although either sequence of BPT or PBT improved jumping, hopping, sprint acceleration, and Standing Stork and Y-Balance, BPT initiated greater training improvements in reactive strength index, absolute and relative leg stiffness, triple hop test, and the Y-Balance test. BPT may provide either similar or superior performance enhancements compared with PBT.

2015-06-01

Media interest in cesarean delivery has grown in recent years driven both by rising cesarean delivery rates and the decision by the American College of Obstetrics and Gynecology (ACOG) to permit elective cesarean (EC) delivery. A content analysis of United States newspaper and magazine articles from 2000 to 2013 (n = 131 articles) was completed to understand how the news media portrays ECs. The majority of articles (71.8%) emphasized reasons to support women having an EC, while 38.2 percent of the articles exhibited themes of physician support for ECs. Relatively few articles mentioned reasons against ECs either from the women's perspective (11.5%) or the practitioners' (3.8%). The most common themes given for women choosing ECs were convenience/scheduling (48.9%), avoidance of pain or fear of labor (29.8%), and physical harm to women from vaginal birth (17.6%). Doctors' perspectives were less prevalent in the media than women's perspectives, but when mentioned they were almost exclusively in support of ECs for reasons including avoiding malpractice (28.2%), avoiding physical harm to the woman or baby (16.8%), and timing/scheduling (14.5%). Media coverage suggests ECs are widely accepted by both women and doctors, with women choosing an EC mainly for convenience/scheduling and fear. However, 43 percent of doctors surveyed by ACOG said they were not willing to perform the procedure, and surveys report that mothers rarely request an EC. © 2015 Wiley Periodicals, Inc.

Newborn screening for proximal urea cycle disorders: Current evidence supporting recommendations for newborn screening.

Science.gov (United States)

Merritt, J Lawrence; Brody, Linnea L; Pino, Gisele; Rinaldo, Piero

2018-04-20

Current newborn screening (NBS) for urea cycle disorders (UCD) is incomplete as only distal UCDs are included in most NBS programs by measuring elevated amino acid concentrations. NBS for the proximal UCDs involves the detection in NBS spots of low citrulline values, a finding which is often overlooked because it is considered to be inadequate. We retrospectively analyzed NBS blood spots from known UCD patients comparing the utility of the Region 4 Stork (R4S) interpretive tools to conventional cutoff based interpretation. This study shows the utility of R4S tools in detecting all UCDs, and provides evidence to support the nomination to add proximal UCDs to the recommended uniform screening panel.

Full Text Available So far, the identity of Cyathostoma (Hovorkonema nematodes collected from respiratory tracts of birds of prey (Accipitriformes, Falconiformes and owls (Strigiformes in Europe and North America is extremely inconsistent. Our results, based on analyses of ITS-2 sequences suggest that the Cyathostoma (Hovorkonema nematodes found in the birds of prey and owls from Central Europe and North America probably belong to the same species, C. (Hovorkonema americana Chapin, 1925. We are convinced, that described in recent literature high ITS-2 divergence among C. (Hovorkonema nematodes collected from Europe, has occurred as a result of invalid synonimisation of some C. (Hovorkonema species. In our opinion C. (Hovorkonema americana (typically parasites of tracheae and air sacs of raptors and C.

Can you catch Ebola from a stork bite? Inductive reasoning influences generalization of perceived zoonosis risk.

Directory of Open Access Journals (Sweden)

Tyler Davis

Full Text Available Emerging zoonoses are a prominent global health threat. Human beliefs are central to drivers of emerging zoonoses, yet little is known about how people make inferences about risk in such scenarios. We present an inductive account of zoonosis risk perception, suggesting that beliefs about the range of animals able to transmit diseases to each other influence how people generalize risks to other animals and health behaviors. Consistent with our account, in Study 1, we find that participants who endorse higher likelihoods of cross-species disease transmission have stronger intentions to report animal bites. In Study 2, using real-world descriptions of Ebola virus from the WHO and CDC, we find that communications conveying a broader range of animals as susceptible to the virus increase intentions to report animal bites and decrease perceived safety of wild game meat. These results suggest that inductive reasoning principles may be harnessed to modulate zoonosis risk perception and combat emerging infectious diseases.

1986-12-01

A wind turbine park has been planned near Urk, formerly an island in the Zuiderzee, and now a location in the IJsselmeerpolders. The project covers the erection of 25 wind turbines of 300 kW each. A short description of the foundations and construction is given. Turbines will be supplied by Hayen Maurice Zepperen in Belgium and the rotors by Stork, Venlo, Netherlands. Rotors will consist of three adjustable blades made of glass reinforced polyester. Yawing will be controlled automatically by a central windvane. There are no safety standards in The Netherlands yet for wind turbines with diameters larger than 20 m, but these turbines are expected to be safe. A number of factors which may produce difficulties are mentioned (noise, accidents, landscape pollution, danger for passing birds). There is also a real danger for damage caused by drifting ice. Finally, the economic and financial factors are discussed.

The occurrence of a coccidian parasite, Cryptosporidium, among birds in the Kuala Lumpur National Zoo was investigated in this study. A hundred bird fecal samples were taken from various locations of the zoo. Fecal smears prepared using direct smear and formalin ethyl acetate concentration technique were stained with modified Ziehl-Neelsen stain. Samples positive for Cryptosporidium with Ziehl-Neelsen stain were later confirmed using the immunofluorescence technique and viewed under the epifluorescence microscope. Six species of bird feces were confirmed positive with Cryptosporidium oocysts. They included Wrinkled Hornbill (Aceros corrugatus), Great Argus Pheasant (Argusianus argus), Black Swan (Cygnus atratus), Swan Goose (Anser cygnoides), Marabou Stork (Leptoptilos crumeniferus), and Moluccan Cockatoo (Cacatua moluccencis). These birds were located in the aviary and lake, with the Moluccan Cockatoo routinely used as a show bird. Results obtained in this study indicated that animal sanctuaries like zoos and bird parks are important sources of Cryptosporidium infection to humans, especially children and other animals.

A Roseate Spoonbill sweeps the water for food in the Merritt Island National Wildlife Refuge, which shares a boundary with Kennedy Space Center. The brilliant pink bird is named for its straight bill with the broad spatulate tip. Preferring a habitat of mangroves, it is usually found on the coasts of southern Florida and Texas, occasionally in Louisiana., in the West Indies, Mexico and Central and South America. Spoonbills feed on shrimps and fish in shallow waters, sweeping their bills from side to side and scooping up whatever they encounter. The 92,000- acre refuge is a habitat for more than 310 species of birds, 25 mammals, 117 fishes and 65 amphibians and reptiles. The marshes and open water of the refuge also provide wintering areas for 23 species of migratory waterfowl, as well as a year-round home for great blue herons, great egrets, wood storks, cormorants, brown pelicans and other species of marsh and shore birds.

Zoological and productivity aspects of silver-fir die-back

Energy Technology Data Exchange (ETDEWEB)

Eichhorn, O.

1985-08-25

Using more recent findings and knowledge concerning root aphids, their taxonomy, host specificity, occurrence, distribution and damaging effect, the article shows that they are not the primary cause of silver-fir die-back despite their high level of constance and that they do not play any part in the course of the disease. Neither can other single insect species or several other insect species together which are harmful to silver firs like shoot bell-moth, bud bell-moth, weevil, longicorn and bark beetle, be blamed to be the primary cause of fir die-back. The article discusses reasons why constance and abundance of the bark beetle is surprisingly low even in seriously diseased trees. External appearance of the health condition of trees (proportion of dried-out crown or stag-headedness, number of needle-leaf generations, stork-nest-type crown configuration) and their rate of annual growth agree well. No phytopathogenic nematodes were detected in the inner bark/sapwood area of the trunks and in the roots of diseased silver firs. Nematodes, therefore, are ruled out as a primary cause of fir die-back.

An infectious agent was isolated from the liver of bobwhite quails (Colinus virginianus, L. 1758). The agent was sensitive to chloroform and its multiplication was inhibited by 5-iodine-2-deoxy-uridine. It passed filters with a pore diameter of 220 nm and more but not 100 nm filters. Electron microscopic examination revealed numerous nucleocapsids with hollow capsomeres and few enveloped particles in the supernatant fluids of infected cultures. The nucleocapsids were calculated to have 162 capsomeres on their surface. Using the plaque reduction method for neutralization tests no serological cross reactions could be detected between the quail isolate and sera against Marek's disease virus, turkey herpes-virus (HV), duck enteritis HV, infectious laryngotracheitis HV, amazon parrot HV, great horned owl HV, eagle owl HV, snowy owl HV, falcon HV, pigeon HV, Lake Victoria Cormorant HV, and stork HV. The isolate from bobwhite quail did only cross-react with antiserum against crane HV. It is concluded that the isolated virus is a member of the avian herpesvirus group and it is proposed to tentatively term it herpesvirus colinum (from Colinus virginianus = bobwhite quail).

The greenish iridescence of a male Anhinga nearly blends into the green vegetation behind it on the grounds of the Kennedy Space Center. The mostly black-bodied bird is also known as a 'snakebird' because, when swimming, only its head and long, slender neck are visible above water. The anhinga inhabits freshwater ponds and swamps with thick vegetation and ranges the Atlantic and Gulf coasts from North Carolina to Texas, the Mississippi Valley north to Arkansas and Tennessee, and south to southern South America. The Center shares a boundary with the Merritt Island National Wildlife Refuge, which encompasses 92,000 acres that are a habitat for more than 331 species of birds, 31 mammals, 117 fishes, and 65 amphibians and reptiles. The marshes and open water of the refuge provide wintering areas for 23 species of migratory waterfowl, as well as a year-round home for great blue herons, great egrets, wood storks, cormorants, brown pelicans and other species of marsh and shore birds, as well as a variety of insects.

A white pelican and several small egrets rest on the bank of a pond in in the waters of the Merritt Island National Wildlife Refuge, which shares a boundary with Kennedy Space Center. White pelicans inhabit marshy lakes and along the Pacific and Texas coasts. They winter from Florida and southern California south to Panama, chiefly in coastal lagoons. They are frequently seen flying in long lines, flapping and sailing in unison, but also ride rising air currents to soar gracefully in circles. The range of the egret includes southern and eastern states, Mexico, Central and South America, and the West Indies. The Refuge encompasses 92,000 acres that are a habitat for more than 331 species of birds, 31 mammals, 117 fishes, and 65 amphibians and reptiles.

A black-necked stilt waits near its nesting mate nest in the Merritt Island National Wildlife Refuge, which shares a boundary with Kennedy Space Center. Stilts usually produce three or four brown-spotted buff eggs in a shallow depression lined with grass or shell fragments. In the nesting season they are particularly agressive. Stilts are identified by a distinct head pattern of black and white, very long red legs, and straight, very thin bill. Their habitat is salt marshes and shallow coastal bays from Delaware and northern South America in the East, and freshwater marshes from Oregon and Saskatchewan to the Gulf Coast. The 92,000-acre wildlife refuge is a habitat for more than 310 species of birds, 25 mammals, 117 fishes and 65 amphibians and reptiles. The marshes and open water of the refuge also provide wintering areas for 23 species of migratory waterfowl, as well as a year-round home for great blue herons, great egrets, wood storks, cormorants, brown pelicans and other species of marsh and shore birds.

The purpose of this study was to examine the effect of 8 weeks combined balance and plyometric training on the physical fitness of female adolescent basketball players. Twenty six healthy regional-level players were randomly assigned to either an experimental group (E; n = 16, age = 16.4 ± 0.5) or a control group (C; n = 10, age = 16.5 ± 0.5). C maintained their normal basketball training schedule, whereas for 8 weeks E replaced a part of their standard regimen by biweekly combined training sessions. Testing before and after training included the Squat Jump (SJ), Countermovement Jump (CMJ), Drop Jump (DJ), 5, 10 and 20-m sprints, Stork Balance Test (SBT), Y-Balance Test (YBT) and Modified Illinois Change of Direction Test (MICODT). Results indicated no significant inter-group differences in SJ and CMJ height; however, E increased their DJ height (ptraining to regular in-season basketball training proved a safe and feasible intervention that enhanced DJ height, balance, and agility for female adolescent basketball players relative to the standard basketball training regimen.

State and Federal agencies are working jointly on structural modifications and improved water-delivery strategies to reestablish more natural surface-water flows through the Everglades wetlands and into Florida Bay. Changes in the magnitude, duration, timing, and distribution of inflows from the headwaters of the Taylor Slough and canal C-111 drainage basins have shifted the seasonal distribution and extent of wetland inundation, and also contributed to the development of hypersaline conditions in nearshore embayments of Florida Bay. Such changes are altering biological and vegetative communities in the wetlands and creating stresses on aquatic habitat. Affected biotic resources include federally listed species such as the Cape Sable seaside sparrow, American crocodile, wood stork, and roseate spoonbill. The U.S. Geological Survey (USGS) is synthesizing scientific findings from hydrologic process studies, collecting data to characterize the ecosystem properties and functions, and integrating the results of these efforts into a research tool and management model for this Southern Inland and Coastal System(SICS). Scientists from all four disciplinary divisions of the USGS, Biological Resources, Geology, National Mapping, and Water Resources are contributing to this interdisciplinary project.

[Microbiological studies in poultry meat production].

Monov, G

1981-01-01

Microbiologic studies were carried out in the production of poultry meat in a poultry dressing combine of the Stork system. Examined were a total of 125 washing samples taken at the 9th, 11th and 15th hour from the scalding vat, the cooling vat, the machine of eviscerating and the skin surface after plucking, eviscerating and shower washing and prior to packing the carcasses. It was found that the count of aerobic organisms continuously rose during the technologic processing of the slaughtered birds with regard to the surface of the carcasses, the peak values of the total counts and that of coliforms being reached during evisceration. It was further established that shower washing of the carcasses immediately following evisceration guaranteed a washing effect so far as the microflora on the surface was concerned, amounting to 77.60 per cent. So far as the coliform bacteria was concerned this effect was found to be equal to 89.78 per cent. The total count of aerobic microflora on the surface of carcasses prior to packing was found to vary within the range of 3000 to 72000, while the count of coliforms ranged from 100 to 1800/cm2.

Does a Working Memory Load Really Influence Semantic Priming? A Self-replication Attempt

Directory of Open Access Journals (Sweden)

Tom Heyman

2017-08-01

Full Text Available The present paper describes two attempts to replicate a recent study of ours in the semantic priming domain (Heyman, Van Rensbergen, Storms, Hutchison, & De Deyne, 2015. In that study, we observed that semantic priming for forward associates (e.g., 'panda-bear' completely evaporated when participants’ working memory was taxed, whereas backward (e.g., 'baby-stork' and symmetric associates (e.g., 'cat-dog' showed no ill-effects of a secondary task. This was the case for relatively long and short stimulus onset asynchronies (i.e., 1,200 ms and 200 ms, respectively. The results thus suggested that prospective target activation is, contrary to what some theories of semantic memory posit, not an automatic process. However, the two replication studies reported here cast serious doubt on this conclusion. A Bayesian analysis of all the available data indicated that there is at least substantial evidence for a priming effect in every condition, except for forward associates in the short SOA condition. The null hypothesis is still supported in the latter condition, though the replication studies weakened the evidence for a null effect. The theoretical implications of these findings are discussed.

The synthesis of retinoid vitamin A-vitamin B 6 conjugate analogues from a vitamin B 6 coenzyme analogue and putative HIV-1 trans-activating transcriptional regulatory protein Tat antagonist (Z)-5 ' -O-phosphono-pyridoxylidenerhodanine (B6PR) monosodium salt hemiheptadecahydrate [(Z)-B6PRNa8.5H 2 O] is discussed here. All-trans-retinoic acid (ATRA) is coupled to B6PR by a modified Stork enamine acylation. It results in a product library of more than eight compounds, each with at least one intact all-trans or 13-cis vitamin A double bond system. This yellow oily concentrate mixture was subjected to matrix-assisted laser desorption/ionization-time-of-flight (MALDI-ToF) mass spectrometry (MS), UV/VIS-spectrophotometry, and proton nuclear magnetic resonance spectroscopy ( 1 H-NMR). The chemical structures of six components of the concentrate mixture could be established by combination of these analytical methods. The two main components are 65% 2 ' C,3O-(all-trans-retinylidyne)B6PT (B6RA) and 25% 2 ' C-(all-trans-retinoyl)B6PT, chemically derived from (5RS)-5-(5 ' -O-phosphono-pyridoxyl)-2,4-thiazolidinedione (B6PT). This new retinoid selection could be of further interest in antiviral applications, especially treating conditions caused by RNA viruses like HIV

Preliminary studies to investigate the effects of organochlorine pesticides on birds was conducted in Lower Moshi, NAFCO West Kilimanjaro, Arusha seed farm, Tropical Pesticides Research Institute (TPRI) farms, Manyara ranch and areas around Lake Victoria as well as in the TPRI laboratory in Tanzania. Large quantities of the pesticides particularly DDT, endosulfan, dieldrin, lindane and toxaphene are still being applied against pests of cotton, coffee, maize, beans and other crops as well as disease vectors in the country. Several groups of birds including waterbirds, African Fish Eagles, Marabou storks, Oxpecker, ducks, etc. were found feeding, roosting and swimming in the water and exposed to other substances that were contaminated with organochlorine pesticides and were presumably at risk. Analytical results from the tissues of the African Fish Eagles collected from Lake Victoria areas showed that the kidneys were contaminated with p,p' DDE and o,p' DDE at levels of 0.4 ng g -1 and 1.45 ng g -1 respectively. These organochlorine insecticides as well as β-HCH were also present in the brain and liver tissues. The levels of the organochlorine residues were well below the lethal and sublethal levels for bird raptors reported in the literature. (author). 7 refs, 2 tabs

In this study pretreatment methods for nanofiltration of paper machine save-all clarified water fractions (clear filtrate) were tested. The clear filtrates resulting from both an acidic and a neutral paper making process were used. Tubular compact modules from Stork-Friesland and a Vibration Shear Enhanced Processing (VSEP) - unit from New Logic Int. equipped with various different membranes were used. It was shown, that pretreatment with porous membranes, such as micro- or ultrafiltration membranes was not economically feasible, because the flux in the nanofiltration stage was not increased. The chemical pretreatment enhanced nanofiltration flux at neutral pH by about 20 % and the amount of irreversible fouling was reduced from 40 % to 20 %. Moreover, the chemical dosage needed was low, 0.5 mg/l. This indicates that chemical pretreatment could turn up to be a feasible way to increase the capacity of a nanofiltration plant. It was also shown, that the VSEP module, which tolerates even some amount of fibre and thus needs only coarse pretreatment, such as bend screens, gave at neutral pH nanofiltration fluxes, which were higher than those obtained earlier with other membrane modules. In general, it was seen, that pH is one of the most important factors affecting the membrane behaviour: at acidic pH lower fluxes and more fouling were obtained. (orig.) 6 refs.

CFD computations of wind turbine blade loads during standstill operation KNOW-BLADE, Task 3.1 report

Energy Technology Data Exchange (ETDEWEB)

Soerensen, N.N.; Johansen, J.; Conway, S.

2004-06-01

Two rotors blades are computed during standstill conditions, using two different Navier-Stokes solvers EDGE and EllipSys3D. Both steady and transient linear {kappa} - {omega} RANS turbulence models are applied, along with steady non-linear RANS and transient DES simulations. The STORK 5.0 WPX blade is computed a three different tip pitch angles, 0, 26 and 50 degrees tip pitch angle, while the NREL Phase-VI blade is computed at 90 degrees tip pitch angle. Generally the CFD codes reproduce the measured trends quite well and the two involved CFD codes give very similar results. The discrepancies observed can be explained by the difference in the applied turbulence models and the fact that the results from one of the solvers are presented as instantaneous values instead of averaged values. The comparison of steady and transient RANS results show that the gain of using time true computations are very limited for this case, with respect to mean quantities. The same can be said for the RANS/DES comparison performed for the NREL rotor, even though the DES computation shows improved agreement at the tip and root sections. Finally, it is shown that the DES methodology provides a much more physical representation of the heavily stalled part of the flow over blades at high angles of attack. (au)

The aim of this study was to compare 3 different available methods for estimating left ventricular end-diastolic pressure (LVEDP) noninvasively in patients with coronary artery disease and preserved left ventricular ejection fraction (EF). We used 3 equations for noninvasive estimation of LVEDP: The equation of Mulvagh et al., LVEDP(1) = 46 - 0.22 (IVRT) - 0.10 (AFF) - 0.03 (DT) - (2 ÷ E/A) + 0.05 MAR; the equation of Stork et al., LVEDP(2) = 1.06 + 15.15 × Ai/Ei; and the equation of Abd-El-Aziz, LVEDP(3) = [0.54 (MABP) × (1 - EF)] - 2.23. ( A, A-wave velocity; AFF, atrial filling fraction; Ai, time velocity integral of A wave; DT, deceleration time; E, E-wave velocity; Ei, time velocity integral of E wave; IVRT, isovolumic relaxation time; MABP, mean arterial blood pressure; MAR, time from termination of mitral flow to the electrocardiographic R wave; Ti, time velocity integral of total wave.) LVEDP measured by catheterization was correlated with LVEDP(1) (r = 0.52, P Aziz, LVEDP = [0.54 MABP × (1 - EF)] - 2.23, appears to be the most accurate, reliable, and easily applied method for estimating LVEDP noninvasively in patients with preserved left ventricular ejection fraction and an LVEDP < 20 mm Hg.

Full Text Available Batu Ampar mangrove is an important bird habitat especially for birds which have relation to mangrove ecosystem in West Kalimantan. The research was conducted in February to March 2007, at mangrove Batu Ampar demo site. Sampling was done to get representative area for bird survey. The 19 transects were chosen as sampling site to collect bird data such as species and number of individual. Bird surveys were carried out using Reconnaissance method and index point of abundance (IPA count method. The length of each transect was approximately 500 m. The results showed that the bird community's structure dominated by insectivorous birds represented approximately 60 % of total bird's species at mangrove Batu Ampar demo site. The abundance numbers of the individual with the bird's species has relation pattern like J opposite. Percentage of dominant bird species was approximately 11%, those are such as stork billed kingfisher, white-collared kingfisher, common iora, chestnuts-rumped babbler, Strip-Tit Babbler, magpie robin, ashy tailorbird, mangrove blue flycatcher, pied fantail, mangrove whistler, Brown-throated Sunbird and Cooper-Throated Sunbird. Vertical structure of mangrove vegetation was used by birds at mangrove Batu Ampar demo site is mainly B stratum, and it used around 60% birds species. Based on dendrogram analysis there were 5 cluster birds species. The mangrove bird specialists found at sampling area were mangrove blue flycatcher and Cooper throated sunbird.

1985-01-01

The major objective of the Division is to examine the influences of natural and man-made stressors on plant and animal populations and communities, primarily in southeastern ecosystems. Special attention is given to understanding the ecology and life history of wildlife populations, particularly those native to the SRP. The research programs are ultimately designed to assess the responses of populations and communities to various perturbations, but emphasis is placed on basic ecological studies that establish the solid foundation of information necessary to conduct applied research. Specific studies have looked at the availability and utilization of habitat types by various species. Biomass and reproduction studies on different vertebrate species have yielded comparative information on variation between populations in different geographic regions. Research on the endangered species that occur on the SRP has provided background data necessary to allow SREL scientists to recommend control and mitigation measures for the American alligator and wood stork. Investigations of waterfowl utilization patterns in reactor-affected and unaffected aquatic habitats on the SRP have yielded valuable information on the effects of reactor operations on these game species. Electrophoretic and morphological measurements have been made on a number of the local vertebrate species in addressing problems in genetics and population dynamics. Special emphasis has been placed on the actual or potential effects of reactor operations on fish, including larval fish in riverine swamp systems, and on several game and non-game species of reptiles and mammals

Anthropogenic areas as incidental substitutes for original habitat.

Science.gov (United States)

Martínez-Abraín, Alejandro; Jiménez, Juan

2016-06-01

One speaks of ecological substitutes when an introduced species performs, to some extent, the ecosystem function of an extirpated native species. We suggest that a similar case exists for habitats. Species evolve within ecosystems, but habitats can be destroyed or modified by natural and human-made causes. Sometimes habitat alteration forces animals to move to or remain in a suboptimal habitat type. In that case, the habitat is considered a refuge, and the species is called a refugee. Typically refugee species have lower population growth rates than in their original habitats. Human action may lead to the unintended generation of artificial or semiartificial habitat types that functionally resemble the essential features of the original habitat and thus allow a population growth rate of the same magnitude or higher than in the original habitat. We call such areas substitution habitats and define them as human-made habitats within the focal species range that by chance are partial substitutes for the species' original habitat. We call species occupying a substitution habitat adopted species. These are 2 new terms in conservation biology. Examples of substitution habitats are dams for European otters, wheat and rice fields for many steppeland and aquatic birds, and urban areas for storks, falcons, and swifts. Although substitution habitats can bring about increased resilience against the agents of global change, the conservation of original habitat types remains a conservation priority. © 2016 Society for Conservation Biology.

Background Passerines (Aves: Passeriformes) dominate modern terrestrial bird communities yet their fossil record is limited. Liang Bua is a large cave on the Indonesian island of Flores that preserves Late Pleistocene–Holocene deposits (∼190 ka to present day). Birds are the most diverse faunal group at Liang Bua and are present throughout the stratigraphic sequence. Methods We examined avian remains from the Late Pleistocene deposits of Sector XII, a 2 × 2 m area excavated to about 8.5 m depth. Although postcranial passerine remains are typically challenging to identify, we found several humeral characters particularly useful in discriminating between groups, and identified 89 skeletal elements of passerines. Results At least eight species from eight families are represented, including the Large-billed Crow (Corvus cf. macrorhynchos), the Australasian Bushlark (Mirafra javanica), a friarbird (Philemon sp.), and the Pechora Pipit (Anthus cf. gustavi). Discussion These remains constitute the first sample of fossil passerines described in Wallacea. Two of the taxa no longer occur on Flores today; a large sturnid (cf. Acridotheres) and a grassbird (Megalurus sp.). Palaeoecologically, the songbird assemblage suggests open grassland and tall forests, which is consistent with conditions inferred from the non-passerine fauna at the site. Corvus cf. macrorhynchos, found in the Homo floresiensis-bearing layers, was likely part of a scavenging guild that fed on carcasses of Stegodon florensis insularis alongside vultures (Trigonoceps sp.), giant storks (Leptoptilos robustus), komodo dragons (Varanus komodoensis), and probably H. floresiensis as well.

Maternal factors associated with fetal growth and birthweight are independent determinants of placental weight and exhibit differential effects by fetal sex.

Directory of Open Access Journals (Sweden)

Marie Cecilie Paasche Roland

Full Text Available INTRODUCTION: Maternal nutritional and metabolic factors influence the developmental environment of the fetus. Virtually any nutritional factor in the maternal blood has to pass the placental membranes to reach the fetal blood. Placental weight is a commonly used measure to summarize placental growth and function. Placental weight is an independent determinant of fetal growth and birthweight and modifies the associations between maternal metabolic factors and fetal growth. We hypothesized that maternal factors known to be related to fetal growth, newborn size and body composition are determinants of placental weight and that effects of maternal metabolic factors on placental weight differ between the genders. METHODS: The STORK study is a prospective longitudinal study including 1031 healthy pregnant women of Scandinavian heritage with singleton pregnancies. Maternal determinants (parity, body mass index, gestational weight gain and fasting plasma glucose of placental weight were explored by linear regression models, stratified by fetal sex. RESULTS: Parity, maternal BMI, gestational weight gain and fasting glucose had positive effects on placental weight. There was a sex specific effect in these associations. Fasting glucose was significantly associated with placental weight in females but not in males. CONCLUSION: Maternal factors known to influence fetal growth, birthweight and neonatal body composition are determinants of placental weight. The effect of maternal factors on placental weight is influenced by sex as illustrated in the relation between maternal glucose and placental weight.

Narrow-front loop migration in a population of the common cuckoo Cuculus canorus, as revealed by satellite telemetry.

Directory of Open Access Journals (Sweden)

Full Text Available Narrow migration corridors known in diurnal, social migrants such as raptors, storks and geese are thought to be caused by topographical leading line effects in combination with learning detailed routes across generations. Here, we document narrow-front migration in a nocturnal, solitary migrant, the common cuckoo Cuculus canorus, using satellite telemetry. We tracked the migration of adult cuckoos from the breeding grounds in southern Scandinavia (n = 8, to wintering sites in south-western Central Africa (n = 6 and back to the breeding grounds (n = 3. Migration patterns were very complex; in addition to the breeding and wintering sites, six different stopover sites were identified during the 16,000 km annual route that formed a large-scale clockwise loop. Despite this complexity, individuals showed surprisingly similar migration patterns, with very little variation between routes. We compared observed tracks with simulated routes based on vector orientation (with and without effects of barriers on orientation and survival. Observed distances between routes were often significantly smaller than expected if the routes were established on the basis of an innate vector orientation programme. Average distance between individuals in eastern Sahel after having migrated more than 5,000 km for example, was merely 164 km. This implies that more sophisticated inherent guiding mechanisms, possibly involving elements of intermediate goal area navigation or more elaborate external cues, are necessary to explain the complex narrow-front migration pattern observed for the cuckoos in this study.

The integration of balance and plyometric training has been shown to provide significant improvements in sprint, jump, agility, and other performance measures in young athletes. It is not known if a specific within session balance and plyometric exercise sequence provides more effective training adaptations. The objective of the present study was to investigate the effects of using a sequence of alternating pairs of exercises versus a block (series) of all balance exercises followed by a block of plyometric exercises on components of physical fitness such as muscle strength, power, speed, agility, and balance. Twenty-six male adolescent soccer players (13.9 ± 0.3 years) participated in an 8-week training program that either alternated individual balance (e.g., exercises on unstable surfaces) and plyometric (e.g., jumps, hops, rebounds) exercises or performed a block of balance exercises prior to a block of plyometric exercises within each training session. Pre- and post-training measures included proxies of strength, power, agility, sprint, and balance such as countermovement jumps, isometric back and knee extension strength, standing long jump, 10 and 30-m sprints, agility, standing stork, and Y-balance tests. Both groups exhibited significant, generally large magnitude (effect sizes) training improvements for all measures with mean performance increases of approximately >30%. There were no significant differences between the training groups over time. The results demonstrate the effectiveness of combining balance and plyometric exercises within a training session on components of physical fitness with young adolescents. The improved performance outcomes were not significantly influenced by the within session exercise sequence.

Full Text Available Introduction: Health Care Networks (HCN are seen as a possibility for articulating and coordinating actions, health services and is a priority in the health system. One strategy to assure their improvement is the Tutorial Education Program (PET-Redes in the health area. Within this context, it is important to understand the challenges and strengths for the effectiveness of HCN to the network care. Objective: To identify and analyze the perceptions of professionals who are preceptors of PET-Networks (Stork/at-risk infants Network and Disabled People Network about the configuration of the network care and the challenges of professional actions related to it. Method: Qualitative study conducted through two focus groups with professionals that are preceptors of the PET-Networks. Thematic analysis was used for data analysis. Results: Both networks presented the following categories related to the network care configuration: access, comprehensive health care and communication. For this care network configuration, some challenges mentioned include geographical and architectural barriers, lack of social support, lack of transportation, failure on care flow and discontinuities in the communicative process. To deal with these challenges, the following strategies were mentioned: implementation of electronic medical records and formulation of specific forums for debate and articulation of actions, among others. It is important to notice that these categories are intertwined and that more challenges than strategies to overcome them were pointed out by the participants. Conclusion: There are several challenges for effective HCN from different levels and the construction of strategies needs to be convened among all persons involved in the HCN

Children from multicultural families face physical, social, mental, and intellectual hurdles; however, relative interventions are lacking in South Korea (hereafter Korea) in this regard. The purpose of this study was to investigate the effects of regular Taekwondo (TKD) training on physical fitness, mood, sociability, and cognitive functions in these children. This study included 30 children from multicultural families in Korea who were randomly assigned to a TKD group ( n = 15) and control group ( n = 15). The children in TKD group underwent 16 weeks of TKD training once a week for 60 min. Each participant underwent a basic fitness test and sociability questionnaire before and after the intervention. Furthermore, we examined the changes in the mood and cognitive function by determining the profile of mood states (POMS), and Stroop color and word test, respectively. Results of the Stork test of balance were significantly higher in the TKD group after intervention ( p < 0.05). In terms of sub-variables, POMS, tension, and depression scores were significantly lower ( p < 0.05) after the intervention, while the vigor score was significantly higher in the intervention group than those in the control group ( p < 0.05). Furthermore, sociability and 'being left out' score, a sub-variable of sociability, was significantly lower ( p < 0.05) after the intervention, while sociability score was significantly higher ( p < 0.05). Our findings suggest that participation in regular TKD training can be effective for balanced improvements in variables of basic fitness and that it exerts a positive effect on the mood and development of sociability.

Commercialisation BIVKIN-based gasification technology. Non-confidential version

Van der Drift, A.; De Kant, H.F.; Rajani, J.B.

2000-08-01

In 1996, the Netherlands Energy Research Foundation (ECN) in Petten, Netherlands, developed and built a circulating fluidized bed gasification process BIVKIN (Dutch abbreviation for biomass gasification installation) in co-operation with Novem, Afvalzorg and Stork. The plant was initially used at the ECN location in Petten for the characterisation of more than 15 different biomass species, including wood, sludge, grass and manure. During this test work, it was discovered that BIVKIN was an ideal tool for gasification of such diverse biomass at various thermal outputs. ECN has been conducting tests to improve the gas quality so that such fuel gas can be used for the generation of electricity by the use of a gas engine. In order to bring the BIVKIN technology to the commercial market, ECN, Shell and HoSt performed a study to evaluate the engineering concept and cost of such a design in detail. With this study, co-financed by Novem, the commercial viability of the BIVKIN technology in the electrical output range of 1 to 5 MW, is determined. For this relatively small scale, it is assumed that the extra positive cash flow due to selling the heat can compensate the higher investment per kW compared to large-scale systems where the produced heat generally cannot be used. This report is a reflection of the study to commercialise the BIVKIN technology. The BIVKIN-technology will be compared with alternative technologies commercially available for the power range under consideration. Both technical and economic evaluations will be presented. 12 refs

Gestational diabetes mellitus (GDM) is a significant risk factor for cardiovascular disease (CVD) in later life, but the mechanism remains unclear. The aim of the study was to investigate indices of glucose metabolism, dyslipidemia, and arterial stiffness (as measured by pulse wave velocity (PWV)), in women with and without a history of GDM, using both the old WHO and new IADPSG diagnostic criteria, at 5 years after the index pregnancy. Dyslipidemia and PWV were used as surrogate markers for CVD risk. The population-based prospective cohort included 300 women from the original STORK study. All participants had an oral glucose tolerance test (OGTT) during pregnancy. Five years later, the OGTT was repeated along with dual-energy x-ray absorptiometry, lipid analysis, and PWV analysis. Measurements were compared between those women who did and did not have GDM based on both the WHO and IADPSG criteria. We found that women with GDM based on the old WHO criteria had higher CVD risk at 5 years than those without GDM, with markedly elevated PWV and more severe dyslipidemia (higher triglycerides (TG)/HDL cholesterol ratio). After adjusting for known risk factors, the most important predictors for elevated PWV and TG/HDL-C ratio at 5-year follow-up were maternal age, BMI, GDM, systolic blood pressure, and indices of glucose metabolism in the index pregnancy. In conclusion, we found a higher risk for CVD, based on the surrogate markers PWV and TG/HDL-C ratio, at 5-year follow-up in women diagnosed with GDM in the index pregnancy when using the old WHO diagnostic criteria.

West Nile virus (WNV) has become a wide-spread arbovirus in Europe and the Mediterranean Basin countries. This emerging zoonotic disease disseminated 13 years ago in North America where its impact on animal and public health has been considerable. Although American corvids have been the most reliable avian sentinels for WN surveillance in the United States, there is so far no data available about the susceptibility of their Western European counterparts to WNV. Clinical follow-up and serum, oral swabs and feathers viral RNA load monitoring was herein performed on wild-caught Carrion crows (Corvus corone) experimentally inoculated with two WNV strains, Is98 that was isolated from a stork in Israel where it elicited high rates of avian deaths in 1998, and Fr2000 which was only associated to sporadic equine cases in Camargue, France in 2000. Inoculated crows were sensitive to both WNV infections and, as expected from the available epidemiological data, Is98 induced a higher mortality rate (100% vs. 33%) and a quicker fatal outcome, with higher viral RNA loads detected in the serum, oral swabs and feathers than in the Fr2000 group. Therefore, Carrion crows should also be a target species for WNV surveillance in Western Europe, where reporting for abnormal mortalities could be completed by viral detection in the herein described avian matrices. These experimental findings also emphasize the peculiarity of the European situation where a large spectrum of WNV genetic and pathotypic variants have been so far isolated despite limited WN disease reports in wild birds.

Avian wildlife as sentinels of ecosystem health.

Science.gov (United States)

Smits, Judit E G; Fernie, Kimberly J

2013-05-01

Birds have been widely used as sentinels of ecosystem health reflecting changes in habitat quality, increased incidence of disease, and exposure to and effects of chemical contaminants. Numerous studies addressing these issues focus on the breeding period, since hormonal, behavioural, reproductive, and developmental aspects of the health can be observed over a relatively short time-span. Many body systems within individuals are tightly integrated and interdependent, and can be affected by contaminant chemicals, disease, and habitat changes in complex ways. Animals higher in the food web will reflect cumulative effects of multiple stressors. Such features make birds ideal indicators for assessing environmental health in areas of environmental concern. Five case studies are presented, highlighting the use of different species which have provided insight into ecosystem sustainability, including (i) the consequences of anthropogenic disturbances of sagebrush habitat on the greater northern sage grouse Centrocercus urophasianus; (ii) the high prevalence of disease in very specific passerine species in the Canary Islands closely paralleling deterioration of formerly productive desert habitat and ensuing interspecific stressors; (iii) fractures, abnormal bone structure, and associated biochemical aberrations in nestling storks exposed to acidic tailings mud from a dyke rupture at an iron pyrite mine near Sevilla, Spain; (iv) newly presented data demonstrating biochemical changes in nestling peregrine falcons Falco peregrinus and associations with exposure to major chemical classes in the Great Lakes Basin of Canada; and (v) the variability in responses of tree swallows Tachycineta bicolor to contaminants, biological and meteorological challenges when breeding in the Athabasca oil sands.

Full Text Available Purpose: Children from multicultural families face physical, social, mental, and intellectual hurdles; however, relative interventions are lacking in South Korea (hereafter Korea in this regard. The purpose of this study was to investigate the effects of regular Taekwondo (TKD training on physical fitness, mood, sociability, and cognitive functions in these children. Methods: This study included 30 children from multicultural families in Korea who were randomly assigned to a TKD group (n = 15 and control group (n = 15. The children in TKD group underwent 16 weeks of TKD training once a week for 60 min. Each participant underwent a basic fitness test and sociability questionnaire before and after the intervention. Furthermore, we examined the changes in the mood and cognitive function by determining the profile of mood states (POMS, and Stroop color and word test, respectively. Results: Results of the Stork test of balance were significantly higher in the TKD group after intervention (p < 0.05. In terms of sub-variables, POMS, tension, and depression scores were significantly lower (p < 0.05 after the intervention, while the vigor score was significantly higher in the intervention group than those in the control group (p < 0.05. Furthermore, sociability and ‘being left out’ score, a sub-variable of sociability, was significantly lower (p < 0.05 after the intervention, while sociability score was significantly higher (p < 0.05. Conclusions: Our findings suggest that participation in regular TKD training can be effective for balanced improvements in variables of basic fitness and that it exerts a positive effect on the mood and development of sociability.

Birds provide an interesting opportunity to study the relationships between body size, limb morphology and bipedal locomotor function. Birds are ecologically diverse and span a large range of body size and limb proportions, yet all use their hindlimbs for bipedal terrestrial locomotion, for at least some part of their life history. Here, we review the scaling of avian striding bipedal gaits to explore how body mass and leg morphology influence walking and running. We collate literature data from 21 species, spanning a 2500× range in body mass from painted quail to ostriches. Using dynamic similarity theory to interpret scaling trends, we find evidence for independent effects of body mass, leg length and leg posture on gait. We find no evidence for scaling of duty factor with body size, suggesting that vertical forces scale with dynamic similarity. However, at dynamically similar speeds, large birds use relatively shorter stride lengths and higher stride frequencies compared with small birds. We also find that birds with long legs for their mass, such as the white stork and red-legged seriema, use longer strides and lower swing frequencies, consistent with the influence of high limb inertia on gait. We discuss the observed scaling of avian bipedal gait in relation to mechanical demands for force, work and power relative to muscle actuator capacity, muscle activation costs related to leg cycling frequency, and considerations of stability and agility. Many opportunities remain for future work to investigate how morphology influences gait dynamics among birds specialized for different habitats and locomotor behaviors. © 2018.

Because balance is not fully developed in children and studies have shown functional improvements with balance only training studies, a combination of plyometric and balance activities might enhance static balance, dynamic balance, and power. The objective of this study was to compare the effectiveness of plyometric only (PLYO) with balance and plyometric (COMBINED) training on balance and power measures in children. Before and after an 8-week training period, testing assessed lower-body strength (1 repetition maximum leg press), power (horizontal and vertical jumps, triple hop for distance, reactive strength, and leg stiffness), running speed (10-m and 30-m sprint), static and dynamic balance (Standing Stork Test and Star Excursion Balance Test), and agility (shuttle run). Subjects were randomly divided into 2 training groups (PLYO [n = 14] and COMBINED [n = 14]) and a control group (n = 12). Results based on magnitude-based inferences and precision of estimation indicated that the COMBINED training group was considered likely to be superior to the PLYO group in leg stiffness (d = 0.69, 91% likely), 10-m sprint (d = 0.57, 84% likely), and shuttle run (d = 0.52, 80% likely). The difference between the groups was unclear in 8 of the 11 dependent variables. COMBINED training enhanced activities such as 10-m sprints and shuttle runs to a greater degree. COMBINED training could be an important consideration for reducing the high velocity impacts of PLYO training. This reduction in stretch-shortening cycle stress on neuromuscular system with the replacement of balance and landing exercises might help to alleviate the overtraining effects of excessive repetitive high load activities.

Full Text Available Gestational diabetes mellitus (GDM is a significant risk factor for cardiovascular disease (CVD in later life, but the mechanism remains unclear. The aim of the study was to investigate indices of glucose metabolism, dyslipidemia, and arterial stiffness (as measured by pulse wave velocity (PWV, in women with and without a history of GDM, using both the old WHO and new IADPSG diagnostic criteria, at 5 years after the index pregnancy. Dyslipidemia and PWV were used as surrogate markers for CVD risk. The population-based prospective cohort included 300 women from the original STORK study. All participants had an oral glucose tolerance test (OGTT during pregnancy. Five years later, the OGTT was repeated along with dual-energy x-ray absorptiometry, lipid analysis, and PWV analysis. Measurements were compared between those women who did and did not have GDM based on both the WHO and IADPSG criteria. We found that women with GDM based on the old WHO criteria had higher CVD risk at 5 years than those without GDM, with markedly elevated PWV and more severe dyslipidemia (higher triglycerides (TG/HDL cholesterol ratio. After adjusting for known risk factors, the most important predictors for elevated PWV and TG/HDL-C ratio at 5-year follow-up were maternal age, BMI, GDM, systolic blood pressure, and indices of glucose metabolism in the index pregnancy. In conclusion, we found a higher risk for CVD, based on the surrogate markers PWV and TG/HDL-C ratio, at 5-year follow-up in women diagnosed with GDM in the index pregnancy when using the old WHO diagnostic criteria.

This study examined improvements in static balance and muscle electromyographic (EMG) activity following a four week progressive training program in 16 middle aged females (mean age = 46.9 ± 8.7 yrs; height 161.1 ± 6.0 cm; weight 65.4 ± 11.2 kg). Participants trained 3 times per week for 4 weeks, for 50 min per session, progressing base of support, stability, vision, resistance and torque in each of six basic exercises. Pre and post training measures of balance included feet together standing, a tandem stance and a one-leg stand (unsupported leg in the saggital plane) performed with the eyes closed, and a Stork Stand (unsupported leg in the frontal plane) with both eyes open and closed. In each position postural deviations were tallied for each individual while muscle recruitment was determined using root mean squared (RMS) EMG activity for the soleus, biceps femoris, erector spinae, rectus abdominis and internal oblique muscles of the dominant foot side. Balance scores were significantly improved post training in both the Balance Error Score System (p training in all muscles in each condition except the soleus in the tandem position, although not all significantly. Reduced biceps femoris activity suggest that improved core stability allowed participants to move from a hip to an ankle postural control strategy through improved coordination of muscles involved in balance and reduced body sway. The core muscles were able to control body position with less activity post training suggesting improved muscle coordination and efficiency. These results suggest that short term progressive floor to BOSU™ balance training can improve standing balance in middle aged women. Copyright © 2015 Elsevier Ltd. All rights reserved.

NERATOOM work on pump development

International Nuclear Information System (INIS)

Hoornweg, C.J.

1976-01-01

The prototype pump has been manufactured by Stork Engineerings Works at Hengelo in 1969. The full-scale test on water has been carried out as part of the procedures of acceptance. Tests on sodium have been carried out in the pumptestfacility of Interatom at Bensberg (W. Germany); these tests started in March 1971 and were finished in October 1972. During that period nearly 6000 hours of pump testing were accomplished, of which 150 hours the pump was subjected to cavitation. During 30 hours the pump was subjected to a cavitation intensity of more than 3% loss of delivery head. At some occasions the loss of delivery head was 7%. The measured NPSH with the tests on sodium was 10m, whereas the NPSH obtained with the tests on water was 9m. Attempts have been made to account for this difference of NPSH-setting on the two liquids concerned. At the end of the tests on sodium (that is after the excecution of the cavitation tests) the delivery head of the pump was 2 m.l.c. less than the rated value. After dismantling the pump it appeared that the surface of the impeller vanes was roughened, especially at those parts where the original sand cast surface had not been polished. Based on the testresults and not being contradicted by calculation-results so far, our opinion is that cavitation in sodium of reactor temperature (550 0 C) most probably is of the same order of magnitude as it is in water of roomtemperature under the same conditions of NPSH, provided the same pump operates in systems that are exact replica of one another

Highly Pathogenic Avian Influenza H5N8 Clade 2.3.4.4b in Germany in 2016/2017

Full Text Available Here, we report on the occurrence of highly pathogenic avian influenza (HPAI H5Nx clade 2.3.4.4b in Germany. Between November 8, 2016, and September 30, 2017, more than 1,150 cases of HPAI H5Nx clade 2.3.4.4b in wild birds and 107 outbreaks in birds kept in captivity (92 poultry holdings and 15 zoos/animal parks were reported in Germany. This HPAI epidemic is the most severe recorded in Germany so far. The viruses were apparently introduced by migratory birds, sparking an epidemic among wild birds across Germany with occasional incursions into poultry holdings, zoos and animal parks, which were usually rapidly detected and controlled by stamping out. HPAI viruses (mainly subtype H5N8, in a few cases also H5N5 were found in dead wild birds of at least 53 species. The affected wild birds were water birds (including gulls, storks, herons, and cormorants and scavenging birds (birds of prey, owls, and crows. In a number of cases, substantial gaps in farm biosecurity may have eased virus entry into the holdings. In a second wave of the epidemic starting from February 2017, there was epidemiological and molecular evidence for virus transmission of the infections between commercial turkey holdings in an area of high poultry density, which caused approximately 25% of the total number of outbreaks in poultry. Biosecurity measures in poultry holdings should be adapted. This includes, inter alia, wearing of stable-specific protective clothing and footwear, cleaning, and disinfection of equipment that has been in contact with birds and prevention of contacts between poultry and wild water birds.

Full Text Available Background and Objectives: Plantar foot is a very active part in leap activities, such as rope jumping and with its small surface playes an important role in balance control. In this research, the effect of 12 week rope jumping exercise was investigated on postural control and static and dynamic balance in 10-13 years old male students with cavus foot. Methods: This quasi-experimental study was done on 450 male students aged 13-10 years in Jarghouyeh sofla. After the initial evaluation by pedescope (qualitative and then measurement by a foot scanner (quantitative and Staheli index, 30 students were selected as samples and were divided into two groups (experimental and control, each 15 cases. To measure the postural control, a foot scanner device was used and changes in plantar center of pressure was recorded for 20 seconds. Static balance was evaluated with stork test and dynamic balance by Y balance test. The subjects of the experimental group participated in a rope jumping training protocol three 45-minute sessions per week for 12 weeks. In this period of time, the subjects of the control group did not participate in any regular physical activity program in this time. Data were analyzed using dependent and independent t-tests. The significance level was considered p<0/05. Results: A 12-week rope jumping exercise improved postural control and static and dynamic balance in patients with cavus foot, which this change was significant (p<0.001. Conclusion: According to the results of this study, rope jumping can be a useful exercise to improve static and dynamic balance and postural control in individuals with cavus foot.

Full Text Available The Chhilchhila Wildlife Sanctuary (76036-76046 E and 29052-30000 N, situated in Kurukshetra District of Haryana provides an important wintering ground for a diverse range of wetland birds. This study was carried out from April 2009 to March 2012 to document the diversity of wetland birds. Altogether 57 species of wetland birds belonging to 37 genera and 16 families were recorded from the study area. Family Anatidae dominated the wetland bird community with 13 species. Among recorded species, 33 were winter migrants, two summer migrants and 22 were resident species. The winter migratory birds did not arrive at this wetland in one lot and at one time. Instead, they displayed a definite pattern specific to species for arrival and departure. They appeared at the wetland during mid-October and stayed up to early April. The composition of birds in major feeding guilds in the study area showed that the insectivore guild was the most common with 35.09% species, followed by carnivore (29.82%, omnivore (19.30%, herbivore (10.53% and piscivore (5.26%. Among the birds recorded in this study area, Darter (Anhinga melanogaster and Painted Stork (Mycterialeucocephala were Near Threatened species. Comb Duck (Sarkidiornismelanotos, listed in Appendix II of CITES, was also spotted in the sanctuary. The spotting of these threatened bird species highlights the importance of Chhilchhila Wildlife Sanctuary as a significant wetland bird habitat in Haryana. However, anthropogenic activities like fire wood collection, livestock grazing, cutting of emergent and fringe vegetation and improper management of the wetland are major threats to the ecology of this landscape.

Slater, LV, Vriner, M, Zapalo, P, Arbour, K, and Hart, JM. Difference in agility, strength, and flexibility in competitive figure skaters based on level of expertise and skating discipline. J Strength Cond Res 30(12): 3321-3328, 2016-Figure skating is an extremely difficult sport that requires a combination of grace, artistry, flexibility, speed, and power. Although many skaters are involved with strength and conditioning programs, there is no current information about differences in off-ice performance measures based on skating discipline and level. The purpose of this study was to compare agility, strength, and flexibility performance based on skating discipline and level. A total of 343 figure skaters from 4 different disciplines (singles, dance, pair, and synchronized skating) and 3 different levels (novice, junior, and senior) completed combine testing with the United States Figure Skating Association. All subjects completed the hexagon agility test, t-test, triple bound jumps, vertical jump, timed tuck jumps, push-ups, v-ups, hand press, front split, seated reach, and stork pose. A multivariate analysis of variance with Scheffe's post hoc was used to identify differences in performance based on skating discipline and level. Mean differences, Cohen's d effect sizes, and 95% confidence intervals were reported for all significant differences. Senior and junior skaters tended to be faster and stronger than novice skaters. Singles, dance, and pair skaters tended to be more agile, stronger, and flexible than synchronized skaters, however, senior synchronized skaters tended to perform better than senior skaters in other disciplines. These results indicate that strength and conditioning professionals should consider skating discipline and level when designing strengthening programs for figure skaters.

Using malaise traps to sample ground beetles (Coleoptera: Carabidae).

Pitfall traps provide an easy and inexpensive way to sample ground-dwelling arthropods (Spence and Niemela 1994; Spence et al. 1997; Abildsnes and Tommeras 2000) and have been used exclusively in many studies of the abundance and diversity of ground beetles (Coleoptera: Carabidae). Despite the popularity of this trapping technique, pitfall traps have many disadvantages. For example, they often fail to collect both small (Spence and Niemela 1994) and trap-shy species (Benest 1989), eventually deplete the local carabid population (Digweed et al. 1995), require a species to be ground-dwelling in order to be captured (Liebherr and Mahar 1979), and produce different results depending on trap diameter and material, type of preservative used, and trap placement (Greenslade 1964; Luff 1975; Work et al. 2002). Further complications arise from seasonal patterns of movement among the beetles themselves (Maelfait and Desender 1990), as well as numerous climatic factors, differences in plant cover, and variable surface conditions (Adis 1979). Because of these limitations, pitfall trap data give an incomplete picture of the carabid community and should be interpreted carefully. Additional methods, such as use of Berlese funnels and litter washing (Spence and Niemela 1994), collection from lights (Usis and MacLean 1998), and deployment of flight intercept devices (Liebherr and Mahar 1979; Paarmann and Stork 1987), should be incorporated in surveys to better ascertain the species composition and relative numbers of ground beetles. Flight intercept devices, like pitfall traps, have the advantage of being easy to use and replicate, but their value to carabid surveys is largely unknown. Here we demonstrate the effectiveness of Malaise traps for sampling ground beetles in a bottomland hardwood forest.

Impaired or excessive fetal growth is associated with adverse short- and long-term health outcomes that differ between ethnic groups. We explored ethnic differences in fetal size and growth from mid pregnancy until birth. Data are from the multi-ethnic STORK-Groruddalen study, a population-based, prospective cohort of 823 pregnant women and their offspring in Oslo, Norway. Measures were z-scores of estimated fetal weight (EFW), head circumference (HC), abdominal circumference (AC) and femur length (FL), in gestational week 24, 32 and 37, measured by ultrasound, and similar measures at birth. Differences in fetal size and growth were assessed using separate Linear Mixed Models including all four time points, with ethnic Europeans as reference. In week 24 South Asian fetuses had smaller AC, but larger FL than Europeans, and slightly lower EFW (-0.17 SD (-0.33, -0.01), p=0.04). Middle East/North African fetuses also had larger FL, but similar AC, and hence slightly higher EFW (0.18 (0.003, 0.36), p=0.05). Both groups had slower growth of AC, FL and EFW from this time until birth, and had -0.61 SD (-0.73, -0.49) and -0.28 SD (-0.41, -0.15) lower birth weight respectively. Ethnic East Asians, on the other hand, were smaller throughout pregnancy and had -0.58 SD (-0.82, -0.34) lower birth weight. Significant ethnic differences remained after adjusting for maternal factors. We observed ethnic differences in fetal size and body proportions already in gestational week 24, and in fetal growth from this time until birth, which were only partly explained by key maternal factors.

Improved curvature-based inpainting applied to fine art: recovering van Gogh's partially hidden brush strokes

Kuang, Yubin; Stork, David G.; Kahl, Fredrik

2011-03-01

Underdrawings and pentimenti-typically revealed through x-ray imaging and infrared reflectography-comprise important evidence about the intermediate states of an artwork and thus the working methods of its creator.1 To this end, Shahram, Stork and Donoho introduced the De-pict algorithm, which recovers layers of brush strokes in paintings with open brush work where several layers are partially visible, such as in van Gogh's Self portrait with a grey felt hat.2 While that preliminary work served as a proof of concept that computer image analytic methods could recover some occluded brush strokes, the work needed further refinement before it could be a tool for art scholars. Our current work makes several steps to improve that algorithm. Specifically, we refine the inpainting step through the inclusion of curvature-based constraints, in which a mathematical curvature penalty biases the reconstruction toward matching the artist's smooth hand motion. We refine and test our methods using "ground truth" image data: passages of four layers of brush strokes in which the intermediate layers were recorded photographically. At each successive top layer (currently identified by the user), we used k-means clustering combined with graph cuts to obtain chromatically and spatially coherent segmentation of brush strokes. We then reconstructed strokes at the deeper layer with our new curvature-based inpainting algorithm based on chromatic level lines. Our methods are clearly superior to previous versions of the De-pict algorithm on van Gogh's works giving smoother, natural strokes that more closely match the shapes of unoccluded strokes. Our improved method might be applied to the classic drip paintings of Jackson Pollock, where the drip work is more open and the physics of splashing paint ensures that the curvature more uniform than in the brush strokes of van Gogh.

Our aim was to examine the impact of gestational diabetes (GDM), from before the GDM-diagnosis is made, on fetal growth trajectories, and to compare it in Europeans and South Asians; two ethnic groups with dissimilar fetal growth patterns. We studied European (n = 349) and South Asian (n = 184) pregnant women, from the population-based STORK-Groruddalen cohort in Oslo, Norway. Mothers were enrolled in early pregnancy, screened for GDM in gestational week 28 ±2, and classified as "non-GDM", "mild GDM" or "moderate/severe GDM". We measured fetal head circumference, abdominal circumference and femur length by ultrasound, and estimated fetal weight in gestational week 24, 32 and 37, and performed corresponding measurements at birth. In non-GDM pregnancies, South Asian fetuses (n = 156) had a slower growth from gestational week 24, compared with Europeans (n = 310). More than two thirds of the European mothers later diagnosed with GDM were overweight or obese in early pregnancy, while this was not observed in South Asians. Fetuses of GDM mothers tended to be smaller than fetuses of non-GDM mothers in week 24, but thereafter grew faster until birth. This pattern was especially pronounced in fetuses of South Asian mothers with moderate/severe GDM. In week 24 these fetuses had a -0.95 SD (95% CI: -1.53, -0.36) lower estimated fetal weight than their non-GDM counterparts. In contrast, at birth they were 0.45 SD (0.09, 0.81) larger. Offspring of GDM mothers were smaller in mid pregnancy, but subsequently grew faster until birth, compared with offspring of non-GDM mothers. This pattern was most prominent in South Asian mothers with moderate to severe GDM. However, the most remarkable characteristic of these fetuses was not a large size at birth, but the small size in mid pregnancy, before the GDM diagnosis was set.

Formal protected areas will not provide adequate protection to conserve all biodiversity, and are not always designated using systematic or strategic criteria. Using a systematic process, the Important Bird and Biodiversity Area (IBA) network was designed to highlight areas of conservation significance for birds (i.e. IBA trigger species), and more recently general biodiversity. Land use activities that take place in IBAs are diverse, including consumptive and non-consumptive activities. Avitourism in Australia, generally a non-consumptive activity, is reliant on the IBA network and the birds IBAs aim to protect. However, companies tend not to mention IBAs in their marketing. Furthermore, avitourism, like other nature-based tourism has the potential to be both a threatening process as well as a conservation tool. We aimed to assess the current use of IBAs among Australian-based avitour companies' marketing, giving some indication of which IBAs are visited by avitourists on organised tours. We reviewed online avitour itineraries, recorded sites featuring in descriptions of avitours and which IBA trigger species are used to sell those tours. Of the 209 avitours reviewed, Queensland is the most featured state (n = 59 tours), and 73% feature at least one IBA. Daintree (n = 22) and Bruny Island (n = 17) IBAs are the most popular, nationally. Trigger species represent 34% (n = 254 out of 747) of species used in avitour descriptions. The most popular trigger species' are wetland species including; Brolga (n = 37), Black-necked Stork (n = 30) and Magpie Goose (n = 27). Opportunities exist to increase collaboration between avitour companies and IBA stakeholders. Our results can provide guidance for managing sustainability of the avitourism industry at sites that feature heavily in avitour descriptions and enhance potential cooperation between avitour companies, IBA stakeholders and bird conservation organisations.

Full Text Available Objectives: To describe the prevalence of the implementation of obstetric interventions for labor and birth in normal-risk women in reference to maternity Stork Network. Methodology: cross-sectional study was performed from April 2014 to January 2015, with 421 participants in the Maternity School Assis Chateaubriand - UFC, admitted during spontaneous or induced labor with a live fetus and single pregnancy term and their fetuses weighing between 2,500 and 4.499g. The data collection instrument was divided into blocks with sociodemographic and clinical characteristics, obstetric, data care during labor, delivery and birth, maternal morbidity, maternal outcome and obstetric practices in categories A and B from WHO and perinatal outcomes. The values ​​are presented as mean ± standard deviation. Results: The age ranged from 13 to 44; the average gestational age at admission was 38.9 ± 1.1 weeks; 52.2% with only one child; 8.6% had a previous cesarean section. There was 96.2% of pre-natal coverage with an average of 6.4 consultations. 76.2% had vaginal delivery. Obstetric practices in category A were more prevalent oxytocin in the third stage (97.1%, partograph (95%, non-invasive methods for pain relief (87.2%, companion (84.6%. While in section B were more of a vaginal examination at 2 hours (50.4% and intravenous infusion (44.9% and oxytocin in the expansion phase (28.8%. The present study had as limitations the loss of some data, which depended on the filling of third parties, which are characteristic of searches in medical records, or any documentary archive because it is a collection of secondary data. Conclusions: It was possible to identify that the "Good labor assistance practices" has been developed in a good proportion considered; however some practices that should be discouraged are still performed relatively frequently.

Full Text Available BACKGROUND: Neonatal body composition has implications for the health of the newborn both in short and long term perspective. The objective of the current study was first to explore the association between maternal BMI and metabolic parameters associated with BMI and neonatal percentage body fat and to determine to which extent any associations were modified if adjusting for placental weight. Secondly, we examined the relations between maternal metabolic parameters associated with BMI and placental weight. METHODS: The present work was performed in a subcohort (n = 207 of the STORK study, an observational, prospective study on the determinants of fetal growth and birthweight in healthy pregnancies at Oslo University Hospital, Norway. Fasting glucose, insulin, triglycerides, free fatty acids, HDL- and total cholesterol were measured at week 30-32. Newborn body composition was determined by Dual-Energy X-Ray Absorptiometry (DXA. Placenta was weighed at birth. Linear regression models were used with newborn fat percentage and placental weight as main outcomes. RESULTS: Maternal BMI, fasting glucose and gestational age were independently associated with neonatal fat percentage. However, if placental weight was introduced as a covariate, only placental weight and gestational age remained significant. In the univariate model, the determinants of placenta weight included BMI, insulin, triglycerides, total- and HDL-cholesterol (negatively, gestational weight gain and parity. In the multivariable model, BMI, total cholesterol HDL-cholesterol, gestational weight gain and parity remained independent covariates. CONCLUSION: Maternal BMI and fasting glucose were independently associated with newborn percentage fat. This effect disappeared by introducing placental weight as a covariate. Several metabolic factors associated with maternal BMI were associated with placental weight, but not with neonatal body fat. Our findings are consistent with a concept

The impact of socio-economic position and integration level on the observed ethnic differences in dietary habits has received little attention. To identify and describe dietary patterns in a multi-ethnic population of pregnant women, to explore ethnic differences in odds ratio (OR) for belonging to a dietary pattern, when adjusted for socio-economic status and integration level and to examine whether the dietary patterns were reflected in levels of biomarkers related to obesity and hyperglycaemia. This cross-sectional study was a part of the STORK Groruddalen study. In total, 757 pregnant women, of whom 59% were of a non-Western origin, completed a food frequency questionnaire in gestational week 28±2. Dietary patterns were extracted through cluster analysis using Ward's method. Four robust clusters were identified where cluster 4 was considered the healthier dietary pattern and cluster 1 the least healthy. All non-European women as compared to Europeans had higher OR for belonging to the unhealthier dietary patterns 1-3 vs. cluster 4. Women from the Middle East and Africa had the highest OR, 21.5 (95% CI 10.6-43.7), of falling into cluster 1 vs. 4 as compared to Europeans. The ORs decreased substantially after adjusting for socio-economic score and integration score. A non-European ethnic origin, low socio-economic and integration scores, conduced higher OR for belonging to clusters 1, 2, and 3 as compared to cluster 4. Significant differences in fasting and 2-h glucose, fasting insulin, glycosylated haemoglobin (HbA1c), insulin resistance (HOMA-IR), and total cholesterol were observed across the dietary patterns. After adjusting for ethnicity, differences in fasting insulin (p=0.015) and HOMA-IR (p=0.040) across clusters remained significant, despite low power. The results indicate that socio-economic and integration level may explain a large proportion of the ethnic differences in dietary patterns.

Full Text Available INTRODUCTION: Birthweight is used as an indicator of intrauterine growth, and determinants of birthweight are widely studied. Less is known about determinants of deviating patterns of growth in utero. We aimed to study the effects of maternal characteristics on both birthweight and fetal growth in third trimester and introduce placental weight as a possible determinant of both birthweight and fetal growth in third trimester. METHODS: The STORK study is a prospective cohort study including 1031 healthy pregnant women of Scandinavian heritage with singleton pregnancies. Maternal determinants (age, parity, body mass index (BMI, gestational weight gain and fasting plasma glucose of birthweight and fetal growth estimated by biometric ultrasound measures were explored by linear regression models. Two models were fitted, one with only maternal characteristics and one which included placental weight. RESULTS: Placental weight was a significant determinant of birthweight. Parity, BMI, weight gain and fasting glucose remained significant when adjusted for placental weight. Introducing placental weight as a covariate reduced the effect estimate of the other variables in the model by 62% for BMI, 40% for weight gain, 33% for glucose and 22% for parity. Determinants of fetal growth were parity, BMI and weight gain, but not fasting glucose. Placental weight was significant as an independent variable. Parity, BMI and weight gain remained significant when adjusted for placental weight. Introducing placental weight reduced the effect of BMI on fetal growth by 23%, weight gain by 14% and parity by 17%. CONCLUSION: In conclusion, we find that placental weight is an important determinant of both birthweight and fetal growth. Our findings indicate that placental weight markedly modifies the effect of maternal determinants of both birthweight and fetal growth. The differential effect of third trimester glucose on birthweight and growth parameters illustrates that

A rapid assessment of biodiversity in the DAE campus, Kalpakkam was carried out. The entire DAE campus of 3000 acres, at Kalpakkam was divided into four representative plots comprising of different landscapes namely (1) undisturbed area with dense vegetation, (2) building area, (3) water bodies with riparian cover and (4) sandy area with meager vegetation for inventorying of charismatic terrestrial/semi-aquatic fauna viz., Mammals, Birds, Reptiles, Amphibians and Butterflies. For birds, early morning surveys were made whereas for mammals evening and night surveys were followed. Midday sampling was followed for butterflies and other animals. Each plot was surveyed twice in a week over a period of one year (April 07' to March 08'). Totally 128 species of animals were identified during the survey and it has highlighted the potential of biodiversity in the campus. The diversity of butterflies is remarkable. Twenty-two butterfly species were encountered. Frogs, toads, lizards and snakes are also diverse. Five species of frogs and one species of toad were recorded. Lizards are more diverse than snakes. Nine species of lizards were encountered. Calotus versicolor is abundant followed by common skink. Totally five species of snakes were recorded. Among them Common bronzedback and Green Vine Snake were predominant. Seventy species of birds were recorded during the survey period. Black crowned night heron, Common house crow, Great cormorant, Oriental white ibis, Painted stork, Cattle egret, Common mynah are more common. Sixteen species of mammals were encountered during the survey. Wild cattle, Jackal, Jungle cat, Toddy cat, Crested porcupine and Indian civet are the major wildlife found. Indian civet and Crested porcupine are elusive animals that are diminishing from wild and their presence at this campus is an indication of less human intervention. (author)

A new method combining a free-form solution for the neutron emissivity and the ratio method (Bonheure et al 2006 Nucl. Fusion 46 725-40) is applied to the investigation of tritium particle transport in JET plasmas. The 2D neutron emissivity is calculated using the minimum Fisher regularization method (MFR) (Anton et al 1996 Plasma Phys. Control. Fusion 38 1849, Mlynar et al 2003 Plasma Phys. Control. Fusion 45 169). This method is being developed and studied alongside other methods at JET. The 2D neutron emissivity was significantly improved compared with the first MFR results by constraining the emissivity along the magnetic flux surfaces. 1D profiles suitable for transport analysis are then obtained by subsequent poloidal integration. In methods on which previous JET publications are based (Stork et al 2005 Nucl. Fusion 45 S181, JET Team (prepared by Zastrow) 1999 Nucl. Fusion 39 1891, Zastrow et al 2004 Plasma Phys. Control. Fusion 46 B255, Adams et al 1993 Nucl. Instrum. Methods A 329 277, Jarvis et al 1997 Fusion Eng. Des. 34-35 59, Jarvis et al 1994 Plasma Phys. Control. Fusion 36 219), the 14.07 MeV D-T neutron line integrals measurements were simulated and the transport coefficients varied until good fits were obtained. In this novel approach, direct knowledge of tritium concentration or the fuel ratio n T /n D is obtained using all available neutron profile information, e.g both 2.45 MeV D-D neutron profiles and 14.07 MeV D-T neutron profiles (Bonheure et al 2006 Nucl.Fusion 46 725-40). Tritium particle transport coefficients are then determined using a linear regression from the dynamic response of the tritium concentration n T /n D profile. The temporal and spatial evolution of tritium particle concentration was studied for a set of JET discharges with tritium gas puffs from the JET trace tritium experiments. Local tritium transport coefficients were derived from the particle flux equation Γ = -D∇n T + Vn T , where D is the particle diffusivity and V

in this enterprise. For all participating in these walks it is great opportunity to observe how the Nature is functioning without much man-kind interference, pure, untouched and imbalanced. They can observe the untouched river banks, non regulated and meandering in its own way. They can recognize new species which are appearing every year on non cultivated glades, around overgrowing mid-forest lakes or on wetlands. They can observe traces of beavers' work: dams, cut trees, beaver lodges built on small streams flowing through the forest. Also the nests of unique black storks are possible to see. They can measure and observe how the climate is changing and how it varies in different ecosystems (forest, glade, river, wetlands) untouched by humans. They can learn that Nature can exists itself without human interference and it becomes more diverse and rich. It is necessary to teach students to the correct understand the changes in Nature, explain how are changing the living and non-living nature, what is the man-made imbalances of Nature and also how to prepare people for climate change. Each year almost 700 - 1000 students and about 100 teachers participate in this ecological learning process. Outdoor education, observations and experimentations are crucial issues of national school curricula referring to all educational levels which is successfully addressed by this program.

located at Titan, Atlas, and Delta launch complexes between 1995 and 1997. No direct impacts to scrub-jays were observed as a result of normal launches. The explosion of the Delta rocket in January 1997 caused direct impacts to the habitat of several scrub-jays families, from fire and debris; however, no scrub-jay mortality was observed. Mortality exceeded reproductive output at all areas over the course of the study. Populations of the southeastern beach mouse (Peromyscus polionotus niveiventris) populations, a Federally listed, threatened species, reside near all the launch complexes. Hurricane Erin and several other tropical storms impacted several areas at the inception of the study in 1995 causing coastal habitat alterations as a result of salt-water intrusion. Both the habitat and the beach mice populations recovered during the course of the study. No direct impacts to southeastern beach mice were observed as a result of normal launch operations. Direct impacts were observed to the habitat as a result of the explosion of the Delta rocket in January 1997. This alteration of the habitant resulted in a shift in use with the mice moving on to the newly burned part of the site. Waterbirds use wetlands and aquatic systems near the launch complexes. Species include the Federally-listed, endangered Wood Stork (Mycteria americana) and several state-listed species of special concern including the Snowy Egret (Egretta thula thula), Reddish Egret (Egretta rufescens rufescens), White Ibis (Eudocimus albus), Roseate Spoonbill (Ajaia ajaja), Tricolored Heron (Egretta tricolor ruficolis), and Little Blue Heron (Egretta caerulea). No impacts to these populations resulting from any launch operations were observed. Gopher tortoises (Gopherus polyphemus) also occur around the launch complexes. Most of those observed appeared to be in good condition; however, upper respiratory tract disease is known to occur in the population. Cape Canaveral Air Station, including areas near active

survival and recruitment estimates from the French CES scheme to assess the relative contributions of survival and recruitment to overall population changes. He develops a novel approach to modelling survival rates from such multi–site data by using within–year recaptures to provide a covariate of between–year recapture rates. This provided parsimonious models of variation in recapture probabilities between sites and years. The approach provides promising results for the four species investigated and can potentially be extended to similar data from other CES/MAPS schemes. The final paper by Blandine Doligez, David Thomson and Arie van Noordwijk (Doligez et al., 2004 illustrates how large-scale studies of population dynamics can be important for evaluating the effects of conservation measures. Their study is concerned with the reintroduction of White Stork populations to the Netherlands where a re–introduction programme started in 1969 had resulted in a breeding population of 396 pairs by 2000. They demonstrate the need to consider a wide range of models in order to account for potential age, time, cohort and “trap–happiness” effects. As the data are based on resightings such trap–happiness must reflect some form of heterogeneity in resighting probabilities. Perhaps surprisingly, the provision of supplementary food did not influence survival, but it may havehad an indirect effect via the alteration of migratory behaviour. Spatially explicit modelling of data gathered at many sites inevitably results in starting models with very large numbers of parameters. The problem is often complicated further by having relatively sparse data at each site, even where the total amount of data gathered is very large. Both Julliard (2004 and Doligez et al. (2004 give explicit examples of problems caused by needing to handle very large numbers of parameters and show how they overcame them for their particular data sets. Such problems involve both the choice of appropriate

. Various measures of microbial community viability have been suggested as measures or indices of soil quality. Community level studies consider species diversity and frequency of occurrence of species. Visser and Parkinson (1992) found that diverse soil microbiological criteria may be used to indicate deteriorating or improving soil quality. They suggested testing the biological criteria for soil quality at three levels: population, community and ecosystem. Microorganisms and microbial communities are dynamic and diverse, making them sensitive to changes in soil conditions (Kennedy and Papendick, 1995). Their populations include fungi, bacteria including actinomycetes, protozoa, and algae. Soil microorganisms form crucial symbiotic relationships with plants, including mycorrhizal infection for P and N acquisition and bacterial infection for fixation of atmospheric N. Authors emphasizing use of biological factors as indicators of soil quality often equate soil quality with relatively dynamic properties such as microbial biomass, microbial respiration, organic matter mineralization and denitrification, and organic matter content (Yakovchenko et al., 1996; Franzluebbers and Arshad, 1997), or soil microbial C, phospholipid analyses and soil enzymes (Gregorich et al., 1997), or total organic C and N (Franco-Vizcaino, 1997). Visser and Parkinson (1992) question the suitability of enzyme assays for microbial activity and soil quality assessments. Waksman (1927), who studied measurements of soil microorganisms that could indicate soil fertility, found that physical and chemical factors as well as soil biology were needed to predict soil fertility. Meso- and macrofauna populations have also been considered as part of soil quality definitions (Berry, 1994). One could choose to use presence or absence of a particular species or population of a particular species as a measure of soil quality. Stork and Eggleton (1992) discuss species richness as a powerful indicator of invertebrate
