Inter-aviary distance and visual access influence conservation breeding outcomes in a territorial, endangered bird
Species extinctions are becoming a global crisis, affecting biodiversity and ecosystem services, with island populations being particularly vulnerable. In response, conservation managers are increasingly turning to ex situ conservation breeding programs to establish assurance populations and provide a source for release and re-establishment of wild populations. The ‘Alalā (Hawaiian crow, Corvus hawaiiensis) is a critically […]
Pre-feeding Agonism and Seasonality in Captive Groups of Chimpanzees (Pan Troglodytes)
Captive chimpanzees fed at regular, predictable intervals are known to exhibit higher rates of aggression immediately prior to, and during feeding. Presumably, anticipation of food creates tensions leading to increased agonistic interactions prior to feeding. This study was conducted to determine if seasonal variabilities might contribute to pre-feeding agonism. A quantitative examination was made looking […]
Socialization strategies and disease transmission in captive colonies of nonhuman primates
In captive research environments for nonhuman primates (NHP), social housing strategies are often in conflict with protocols designed to minimize disease transmission. This is particularly true in breeding colonies, and is especially relevant when attempting to eliminate specific pathogens from a population of primates. Numerous strategies have been used to establish such specific pathogen free […]
