Application of an enzyme immunoassay for urinary follicle-stimulating hormone to describe the effects of an acute stressor at different stages of the menstrual cylce in female laboratory macaques

In the stress study [capture and restraint], we found that stressors occurring during the luteal-follicular transition not only resulted in acute perturbations of FSH but also led to abnormalities in the subsequent menstrual cycle in 50% of the cases.

Postresearch retirement of monkeys and other nonhuman primates

Though discussions have often focused more on chimpanzees than on monkeys, the added attention to the former species is disproportionate to the far greater number of monkeys used in research in the United States,for whom retirement considerations are equally warranted....

Coping with conflict during initial encounters in chimpanzees

When strangers meet, conflict is likely to arise from incompatibilities in motivations and expectations, as well as from the absence of predictability in interactions. This study explores the mechanisms that mitigate aggression, permit mutual evaluation, establish tolerance, and facilitate the...

Use of temporary and semitemporary enrichment objects by five chimpanzees

The results of this study emphasize the importance of temporary object rotation and presentation of both temporary [paper, magazines, raisin boards, cardboard boxes, etc.] and semitemporary [nets, climbing structures, straw, grass, etc.] objects to captive chimpanzee environments. This work has...

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.

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.
