Environmental change and housing conditions result in disappearance and return of reproductive seasonality in rhesus macaqes (Macaca mulatta)

Rhesus macaques in their natural environments, as well as in the free-ranging colony at Cayo Santiago, Puerto Rico are highly seasonal breeders. Many animal species lose breeding seasonality when brought under captive conditions. The present study that covers a period...

Social knowledge and signal in primates

Primates are notable for having a rich and detailed understanding of their social environment and there has been great interest in the evolution and function of social knowledge in primates. Indeed, primates have been shown to have impressive understandings of...

The effects of music on animal physiology, behavior and welfare

Physiological and psychological effects of listening to music have been documented in humans. The changes in physiology, cognition and brain chemistry and morphology induced by music have been studied in animal models, providing evidence that music may affect animals similarly...

Full-contact social housing of non-human primates (Macaca mulatta and Macaca fascicularis) in a biomedical research facility: Initiation and implementation

Animal welfare regulations have required social housing of primates for more than two decades, although many veterinary and scientific exemptions have been approved with oversight by Institutional Animal Care and Use Committees (IACUCs). In recent years pressure has increased to...

Variables affecting indoor pairing success in adult rhesus macaques (Macaca mulatta)

In research centers that study primates, pairing unfamiliar subjects is the most costly and difficult problem that staff face. Recent studies in adult rhesus macaques suggest that social competence and sociality, as measured by ease of forming new relationships, is...

Novel enrichment item for non-human primates

Wheat grass kits are available from multiple sources (e.g. wheatgrasskits.com) and usually come with enough seeds and other materials to grow 5 flats. The instructions are very simple and the grass grows quickly, only taking about a week to reach...

Pairing rhesus macaques (Macaca mulatta): methodology and outcomes at four national primate research centers

Pairing laboratory macaques is a high priority goal for many behavioral management programs. There are numerous methodological differences in introduction procedures across facilities, including the intermediate stages used between single housing and full contact. A retrospective database of 4325 isosexual...

Comparing options for pair housing rhesus macaques using behavioral welfare measures

In a biomedical research environment, research or management procedures may render continuous full contact pairing of rhesus macaques (Macaca mulatta) unfeasible. This study aimed to determine whether separation on a frequent basis or housing in adjacent cages with tactile contact...

Use of visual barriers by breeding groups of long-tailed macaques (Macaca fascicularis): An indication of color or location preference?

Visual barriers have been shown to be valuable environmental components of nonhuman primate housing to break visual contact between conspecifics as well as between primates and their human keepers. The effect of visual barriers can be to reduce aggression and...
