In North American zoos, hamadryas baboons (Papio hamadryas) have traditionally been housed as single one‐male units (single male groups). In recent years, efforts have been made to house hamadryas in groups composed of multiple one‐male...
Environmental enrichment is a tool used to promote the welfare and well‐being of captive animals by encouraging the display of species‐specific behaviors and reducing the stress or boredom induced by captive environments. Lemurs are highly...
Digital devices, including tablet computers and other touchscreens, can potentially serve as flexible and convenient means for providing behavioral enrichment activities to captive primates. Despite increased interest in incorporating technology into enrichment programs, no direct...
From May- July 2014, I conducted research within a private spider monkey sanctuary, Ecoparque el Fenix, in Campeche, Mexico, home to 20 spider monkeys obtained from the illegal pet trade. Limited financial resources had resulted...
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...
In this study, I combine both physiological and behavioural measures of well-being to comprehensively assess the unique needs of individually-housed captive macaques (Macaca spp.) at OPR Coastal Primate Sanctuary in Longview, WA, with the aim...
The illegal wildlife trade, especially of live animals, is a major threat to slow lorises. Large numbers of confiscated slow lorises are sent to rescue facilities. We aimed to describe the occurrence and types of...
Cortisol levels are often used as a physiological measure of the stress response in captive primates, with noninvasive measures of this being an important step in welfare assessment. We report a method of collecting saliva...
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...
There are few studies of long-term care and rehabilitation of animals which acquired physical disabilities in captivity, despite their importance for welfare. An adult male chimpanzee named Reo at the Primate Research Institute of Kyoto...
