The endangered red panda (Ailurus fulgens) is held in zoos worldwide. The aim of this study was to examine how red pandas are kept and managed in captivity and to compare it with the management guidelines. Sixty-nine zoos, mainly from Europe but also from North America and Australia/New Zealand, responded to our survey. The results revealed that in general zoos follow the management guidelines for most of the investigated issues. The average enclosure is almost four times larger than the minimum size recommended by the management guidelines, although seven zoos have smaller enclosures. About half the zoos do not follow the guidelines concerning visitor access and number of nest boxes. Other issues that may compromise animal welfare include proximity of neighboring carnivore species and placement of nest boxes. © 2010 Wiley-Liss, Inc.

Protecting an endangered and highly poached species can conflict with providing an open and ecologically connected landscape for coexisting species. In Kenya, about half of the black rhino (Diceros bicornis) live in electrically fenced private conservancies. Purpose-built fence-gaps permit some landscape connectivity for elephant while restricting rhino from escaping. We monitored the usage patterns at these gaps by motion-triggered cameras and found high traffic volumes and predictable patterns of prey movement. The prey-trap hypothesis (PTH) proposes that predators exploit this predictable prey movement. We tested the PTH at two semi-porous reserves using two different methods: a spatial analysis and a temporal analysis. Using spatial analysis, we mapped the location of predation events with GPS and looked for concentration of kill sites near the gaps as well as conducting clustering and hot spot analysis to determine areas of statistically significant predation clustering. Using temporal analysis, we examined the time lapse between the passage of prey and predator and searched for evidence of active prey seeking and/or predator avoidance. We found no support for the PTH and conclude that the design of the fence-gaps is well suited to promoting connectivity in these types of conservancies. © 2015 Dupuis-Desormeaux et al.

A wide variety of infectious and non-infectious diseases has been described in bears. Some viral (e.g. canine distemper, infectious canine hepatitis), bacterial (e.g. salmon poisoning) and parasitic diseases (particularly skin mites and ascarid infections) are of concern. Non-infectious conditions, such as dental disease, degenerative joint disease and neoplasia, are very important in the management of captive bears. Appropriate anaesthesia is essential in both veterinary and biological interventions with bears. © 2010 The Authors. Journal compilation © 2010 The Zoological Society of London.

Androgen receptor genes (. AR) have been found to have associations with reproductive development, behavioral traits, and disorders in humans. However, the influence of similar genetic effects on the behavior of other animals is scarce. We examined the loci AR glutamine repeat (. ARQ) in 44 Grevy's zebras, 23 plains zebras, and three mountain zebras, and compared them with those of domesticated horses. We observed polymorphism among zebra species and between zebra and horse. As androgens such as testosterone influence aggressiveness, AR polymorphism among equid species may be associated with differences in levels of aggression and tameness. Our findings indicate that it would be useful to conduct further studies focusing on the potential association between AR and personality traits, and to understand domestication of equid species. © 2015.

The Grevy's zebra (Equus grevyi) is an endangered equid found in northern Kenya and Ethiopia on rangelands often shared by pastoral populations. The Grevy's zebra population has experienced a significant decline in the past 40 years from approximately 15,000 individuals to around 2,000-5,000. For this trend to be reversed, local people that share the pasture-land with Grevy's zebra must be involved. This study sought to identify the beliefs and levels of importance ascribed to Grevy's zebra by local people. In-depth surveys conducted in the region indicated that males and those with fewer numbers of livestock viewed the Grevy's more favorably. In addition, most respondents identified few direct benefits of the zebra, but individuals from areas with minimal tourism perceived the Grevy's zebra as providing financial benefits (e.g., via safaris). Findings suggest that outreach to local communities is needed about the benefits of the species as well as its population decline. © 2012 Copyright Taylor and Francis Group, LLC.
