Preliminary data showing potential for salivary C-reactive protein as an indicator of welfare in western lowland gorillas (Gorilla gorilla gorilla)

C-reactive protein (CRP) is an acute phase protein often used as a biomarker for inflammation related to acute trauma or chronic illness. Animal studies showing elevations in CRP following events such as road transport and moving to new housing suggest that CRP fluctuations may indicate how behavioral stress affects animal welfare. As part of a […]

The influence of captive adolescent male chimpanzees on wounding: management and welfare implications

Abstract 10.1002/zoo.20243.abs Adolescence, the period lasting from the onset of puberty to the emergence of physical and sexual maturity, is a period of social change for many species including chimpanzees. Several reports have implicitly linked the physiological changes that occur during male chimpanzee adolescence to significant disruption in the social group, which in turn may […]

The effects of group type and young silverbacks on wounding rates in western lowland gorilla (Gorilla gorilla gorilla) groups in North American zoos

In North American zoos, male gorillas are often housed in all-male (bachelor) groups to provide socialization for males not managed in breeding groups. These groups exhibit long-term cohesion and stability and males in bachelor groups are no more aggressive than males in mixed-sex groups. Previous studies have shown that aggression in male gorillas is more […]
