Sleep-related behavioural adaptations in free-ranging anthropoid primates

From a socioecological perspective, the first principle underlying sleeping on non-human primates ... is that safety from predators is paramount. .. Sleeping sites must afford the primates some measure of security. Most primates are arboreal, and they sleep as well...

Effects of physical enrichment on agonistic and exploratory behaviours of several groups of lesser mouse lemurs, Microcebus murinus, in captivity

The aim of this study was to evaluate environmental enrichments [branches, foraging devices] intended to decrease aggression [of this semi-solitary nocturnal prosimian] and to increase the diversity of their behavioural repertoire.

American Society of Primatologists guidelines for the ethical treatment of nonhuman primates

Despite their varied disciplines, ASP members hold the following general principles in common:1. The most important of these principles is that we accept the responsibility of stewardship for nonhuman primates, and this responsibility must [emphasis added by authors of this...

Puzzle feeders and gum feeders as environmental enrichment for common marmosets

The results of this study indicate that gum feeders and Puzzle-Feeders' loaded with waxmoth larvae are useful for reducing the rates of pacing and inactivity in single-housed and in pair-housed marmosets.

The Sacred Monkeys of Bali

Excellent overview of species-typical behavior of wild long-tailed macaques. The study tropp spent more than 97 percent of their time in the trees. ... It is very doubtful, however, that terrestriality ever exceeded 10 percent of the day.

Effective strategy for evaluating tactile enrichment devices for singly caged macaques

We present a simple, yet effective, tactile device scoring system used with singly caged macaques indicating that creating and documenting enrichment ideas can be accomplished without a large personnel and budgetary commitment.Abstract of this work has been published in: Contemporary...

Rhesus macaque (Macaca mulatta) group formation and housing: Wounding and reproduction in a specific pathogen free (SPF) colony

Initially small groups were formed consisting of one male and up to eight females. Subsequently larger groups [about 3 males and 21 females] were formed by releasing group members simultaneously or incrementally. Wounding rates were higher among males than among...

The monkey cave: The dark lower-row cage

The typical lower-row cage provides a cave-like housing environment which may impair well-being, invalidate research data, and undermine good housekeeping.

Can puzzle feeders be used as cognitive screening instruments? Differential performance of young and aged female monkeys on a puzzle feeder task

The monkeys' interest seemed directed more toward the task than the reward, as evidenced by the observation that animals would occasionally discard an uneaten pellet in order to work on the task at the next level of difficulty.

Are legal cage space requirements sound? Laboratory Primate Newsletter 38(2), 5-6

In order to make the minimum cage space requirements of the Animal Welfare Act more realistic, an amendment is needed which explicitly states that perches, ledges, swings, or other suspended fixtures have to be placed in such a way that...
