The white rhino is one of the great success stories of modern wildlife conservation, growing from as few as 50-100 animals in the 1880s, to approximately 20,000 white rhinoceros remaining today. However, illegal trade in conservational rhinoceros horns is adding constant pressure on remaining populations. Captive management of ex situ populations of endangered species using molecular methods ca...

Chronic wasting disease (CWD), the only known wildlife prion disease, affects deer, elk and moose. The disease is an ongoing and expanding problem in both wild and captive North American cervid populations and is difficult to control in part due to the extreme environmental persistence of prions, which can transmit disease years after initial contamination. The role of exogenous factors in CWD ...

BACKGROUND Ivermectin is widely used in veterinary practice for the treatment of ecto- and endo-parasites. In wildlife, an extra-label use this parasiticide is sometimes associated with toxicity. Different treatment regimens have been used in ivermectin toxicosis. The present report describes a successful reversal of ivermectin toxicity by intravenous administration of a commercially available ...

Raptors are top predators sensitive to changes and perturbations in the food chain, and as a consequence, they function as good bioindicators for environmental and ecosystem health. Captive breeding facilities have been created at research centers or universities to study biological traits of several raptor species (e.g., the American Kestrel (Falco sparverius) has been used as a wildlife study...

salmonella spp. are zoonotic enteric bacteria able to infect humans, livestock and wildlife. the aim of this study was to investigate the prevalence of salmonella (spp.) and to determine antibiotic susceptibility, serogrouping and presence of inva gene (salmonella invasion gene a) in the detected strains in wild captive herbivores in iran. the fecal samples of 103 animals from 8 different sp...

With global surface air temperature rising rapidly, extensive research effort has been dedicated to assessing the consequences of this change for wildlife. While impacts on phenology, distribution, and demography wild animal populations are well documented, impact increasing cognition in these received relatively little attention. Cognition encompasses mental mechanisms that allow individuals p...

Although transmission of human hepatitis B virus (HBV) variants to nonhuman primates is well documented, it remains to be elucidated whether nonhuman primate HBV is transmissible to humans. The prevalence and transmission routes of gibbon HBV were analysed in 101 captive gibbons in Thailand. Approximately 40 % of these animals showed at least one marker of HBV infection; 19 animals were chronic...

Efficacy of Compound 1080 LP Collars was studied under pen and field conditions. Coyotes poisoned themselves by attacking collared sheep and biting the collars. In 54 pen tests where 1 or 2 captive coyotes had opportunity to attack 1 collared lamb, 41 lambs were attacked and 26 collars were punctured. Of 25 different coyotes offered lambs with collars containing 5 or 10 mg sodium fluoroacetate ...

Inbreeding depression can be reduced, or purged, by selection against deleterious alleles. This prediction is the basis of the recommendation that captive wildlife populations suffering from inbreeding depression be intentionally bred from healthy inbred animals. Yet data on the effectiveness of purging inbreeding depression are few. In this study I present and use two different regression mode...
