Behavioral management as a coping strategy for managing stressors in primates: the influence of temperament and species

Primates involved in biomedical research experience stressors related to captivity, close contact with caregivers, and may be exposed to various medical procedures while modeling clinical disease or interventions under study. Behavioral management is used to promote behavioral flexibility in less...

Exploring dietary practices and faecal consistency in zoo-housed cotton-top tamarins Oedipomidas oedipus

The cotton-top tamarin Oedipomidas oedipus is currently classified as critically endangered by the IUCN, prompting intensive conservation efforts, including the maintenance of healthy populations under human care. However, ensuring optimal welfare and health remains challenging, particularly in terms of nutritional...

Effect of noise on bornean orangutans’ glucocorticoid metabolite (GCM) levels

Zoos are increasingly hosting out-of-hours events such as ‘Music Nights’ to increase visitation, raising potential animal welfare concerns due to anthropogenic noise pollution. This study examined the physiological stress response, measured through faecal glucocorticoid metabolite (FGCM), of Bornean orangutans (Pongo...

Developing and validating a holistic welfare assessment tool for zoo-housed great apes: Integrating resource-based measures with behavioural ecology insights

Assessing the welfare of zoo-housed great apes is essential to ensure high standards of care, maintain zoos’ ethical and educational credibility, and support their conservation roles. However, welfare assessment remains challenging due to the complex cognitive, social, and behavioural needs...

Effects of hand-rearing and group size on chimpanzee (Pan troglodytes) social competence in captivity

The behavior of individual animals reflects both internal states and external context. For captive animals, their early life experiences can influence later adjustment, particularly their social competence. In addition, the way in which they are housed and their current social...

The enriched mind: Cognitive stimulation and behavior in non-human primates

Non-human primates (NHPs) possess high cognitive abilities that enable them to respond effectively to complex social, ecological, and psychological challenges. These abilities need to be stimulated in non-human primates under human care in zoos, conservation centers/sanctuaries, or research facilities, where...

Supportive nutrition for elderly chimpanzees: A case study on non-invasive supplementation in a group setting

Ageing chimpanzees Pan troglodytes in zoological settings often experience physiological decline, including loss of body condition and muscle mass, which can negatively impact welfare and longevity. Over a three-year period, three elderly chimpanzees at Antwerp Zoo exhibited rapid and unexplained...
