Monkeys first arrived in the Comparative Biology Centre (CBC) at Newcastle University in 2000. They were housed in three small separate units consisting of steel and wooden cages. In 2011 a decision was made to...
"Do any of you give cooked food like pasta, potatoes or vegetables to non-human primates? What’s your experience? Do the animals benefit from cooked food; do they like it; does it affect their health in...
"When you keep adult Rhesus macaque (Macaca mulatta) males, adult Cynomolgus (Macaca fascicularis) males or adult Vervet males (Chlorocebus pygerythrus), in the same enclosure, is it advisable to have the canines of the males blunted...
Previous research has highlighted the varied effects of auditory enrichment on different captive animals. This study investigated how manipulating musical components can influence the behavior of a group of captive western lowland gorillas (Gorilla gorilla...
We investigated how forage material affects indicators of welfare in three male Western lowland gorillas (Gorilla gorilla gorilla) at the Detroit Zoo. In addition to their maintenance diet and enrichment foods, the gorillas generally received...
It is widely known that the psychological wellbeing of captive animals can become compromised by a captive environment that lacks proper environmental stimulation. Environmental enrichment programs have become the norm in captive environments yet research...
The use of enzyme immunoassays (EIA) for the non-invasive measurement of glucocorticoids provides a valuable tool for monitoring health and welfare in sensitive species. We validated methods for measuring fecal glucocorticoid metabolites (FGM) using the...
The degree to which the relatively smaller area of artificial environments (compared with natural habitats) has measureable effects on the behavior and welfare of captive animals has been debated for many years. While there is...
The field of primate behavior management has had only limited success in preventing and treating abnormal behaviors, such as stereotypy and self‐injury, in captive non‐human primates (NHP). In contrast, applied behavior analysts have had great...
Facial thermography has enabled researchers to noninvasively and continuously measure the changes of a range of emotional states in humans. The present work used this novel technology to study the effect of positive and negative...
