Do rhesus monkeys recognize themselves in mirrors?
Abstract Self-recognition continues to attract attention because of the evidence of a striking difference between the great apes and humans, on the one hand, and all other primates; the former are capable of self-recognition, whereas no compelling evidence exists for prosimians, monkeys, or lesser apes. This is in spite of numerous attempts to facilitate mirror […]
The effects of predictability in daily husbandry routines on captive rhesus macaques (Macaca mulatta)
Rhesus macaques (Macaca mulatta) housed indoors experience many routine husbandry activities on a daily basis. The anticipation of these events can lead to stress, regardless of whether the events themselves are positive or aversive in nature. The specific goal of this study was to identify whether increasing the predictability of husbandry events could decrease stress […]
Risk Factor Analysis May Provide Clues to Diarrhea Prevention in Outdoor-Housed Rhesus Macaques (Macaca mulatta)
Seventy-five percent of rhesus macaques at national primate research centers are housed outside. Annually, 15–39% of these animals experience diarrhea and require veterinary treatment for dehydration, electrolyte imbalance, or weight loss. An estimated 21–33% of these patients will die or be euthanized. Many studies have explored the various infectious etiologies of non-human primate diarrhea. However, […]
Risk factors for stereotypic behavior and self-biting in rhesus macaques (Macaca mulatta): Animal’s history, current environment, and personality
Captive rhesus macaques sometimes exhibit undesirable abnormal behaviors, such as motor stereotypic behavior (MSB) and self-abuse. Many risk factors for these behaviors have been identified but the list is far from comprehensive, and large individual differences in rate of behavior expression remain. The goal of the current study was to determine which experiences predict expression […]
