Personality traits modulate stress responses after enclosure change of captive capuchin monkeys (Sapajus libidinosus)

Husbandry procedures may cause behavioral and physiological changes to animals living in captivity. However, an individual’s reaction is not uniform and may be related to different coping strategies. In this study, we analyzed whether and how 12 adult captive capuchin...

In-Homecage Blood Collection from Conscious Stumptailed Macaques

Six adult female stumptailed macaques (Macaca aretoides) were trained within a two week period to actively co-operate during in-homecage venipuncture rather than in a restraint apparatus away from the homecage. The training was based on consistent firmness, gentleness and patience....

Pole-and-collar training of macaques: a discussion by the Laboratory Animal Refinement and Enrichment Forum

I am currently pole-and-collar training one of our adult pair-housed rhesus females and hope to get her to graduate to the chair in the next few weeks. Winnie remains sitting when I move the pole towards her but squirms when...

Howletts and Port Lympne Zoo Parks, UK, Summer 1990 – Summer 1991

Several structural enrichment enhancers are described. When a barrel with an opening in the front was hung from the roof of the siamang enclosure, our then solitary male, Mitch, spent much of his time looking out at the world from...

Environmental enrichment and the rehabilitation of nonhuman primates

This paper outlines the change in behavior in chimpanzees, baboons and a hybrid baboon/rhesus macaque that underwent extensive rehabilitation efforts, including a move to group housing and a larger, more complex enclosure. Upon transfer to the new environment, the subjects...

An Enrichment Device for Great Apes

The influence of an environmental enrichment feeding device (puzzle feeder), on activity and behaviour patterns of captive orang-utans, gorillas and chimpanzees was studied at London Zoo. General activity levels and behaviours directed towards the feeder increased for all species when...

Behaviour and Preferences Among Deep Litters in Captive Capuchin Monkeys (Cebus Capucinus)

A captive group of white-faced capuchins, Cebus capucinus, was presented with four deep litters in simultaneous choice (or preference) tests. A floor covering of ground corn cob, woodchips, wood wool or peat was presented once in each quarter of the...

Accuracy of smartwatches for measuring heart rate and oxygen saturation in cynomolgus macaques compared to clinical standards

Continuous monitoring of physiological parameters in non-human primates (NHPs) necessitates a precise, non-invasive, and convenient method. This study aimed to validate the use of smartwatches with integrated pulse oximetry and heart rate (HR) monitoring capabilities for use in NHPs. Currently,...

Five-domain-based evaluation of environmental enrichment in Japanese macaques (Macaca fuscata) to reduce aggressive behavior

Compared with wild troops, Japanese macaques (Macaca fuscata), which are commonly housed in cage-like enclosures in zoos and laboratories, face limited feeding opportunities, leading to intense competition and frequent aggression. Such aggression often results in injuries, highlighting the need for...

Review of depressive-like behaviours in some group-living mammals

Thanks to animal models of depression, we are getting closer to understand the nature of this disorder in humans – but depressive disorders may not be specific only to humans. Although due to the inability to collect a verbal report...
