Amphibians and reptiles differ in many respects from the mammals and birds most commonly used in biomedical research. These differences affect the physical and biological requirements of amphibians and reptiles in captivity. In this contribution...
When forage materials [chicken scratch] are provided, bedding materials, such as straw or shredded newspaper, along with woodchips increase the amount of time the captive chimpanzee spends in search of forage materials. ... Whether this...
The sequence in which 14 laboratory rhesus macaques left their home enclosure during a routine catching procedure was recorded on 30 occasions during 6 weeks. The animals were trained to voluntarily exit one by one...
