Macaque monkeys are widely used to study vision. In the traditional approach, monkeys are brought into a lab to perform visual tasks while they are restrained to obtain stable eye tracking and neural recordings. Here...
Acoustic noise and other environmental variables represent potential confounds for animal research. Of relevance to auditory research, sustained high levels of ambient noise may modify hearing sensitivity and decrease well-being among laboratory animals. The present...
Enrichment devices are important tools to engage zoo-housed animals in species-specific natural behaviours, which is critical to ensure animal welfare. The gelada Theropithecus gelada has a unique graminivorous feeding ecology, yet there is minimal enrichment...
Social housing improves the well-being of monkeys in research settings; however, little is known about factors influencing the long‐term stability of established, full-contact pairs. Archival data were examined to determine whether sex, age, weight, duration...
Animal welfare is critical to buffer stress in captive animals and to ensure the reliability of data from studies. The most usual environmental enrichment technique (EE) for social non-human primates is the social enrichment. However...
Functional analysis (FA) is a method developed and used by behavior analysts in human clinical settings to identify possible environmental variables that reinforce undesired behavior. FA is increasingly being applied to better understand the behavior...
The re-release of golden lion tamarins (Leontopithecus rosalia), from zoos into the wild, is considered to be an ex situ conservation success story. However, zoo-born golden lion tamarins have lower survival rates than their wild-born...
This study aimed at evaluating the effects of unpredictability on behavioral and clinical aspects of Geoffroy's woolly monkey (Lagothrix cana cana) - a frugivorous Amazonian primate species - under human care. We studied seven individuals...
Head orientation is a measure of attention used in behavioral psychological research with non-human primates. It is used across a broad range of disciplines and settings, from the field to the laboratory. Field methods are...
Chimp Haven is a sanctuary for chimpanzees being retired from biomedical research and from facilities that can no longer care for them. Chimpanzees often live in smaller groups in captive settings; however, Chimp Haven integrates...
