Effects of positive reinforcement training on infant behavioral development in nursery-reared rhesus macaques (Macaca mulatta)

At the California National Primate Research Center, one key to long-term success of macaque breeding colonies is to develop effective infant-rearing strategies that minimize the emergence of behavioral pathologies, which can be one indicator of welfare. Positive reinforcement training (PRT)...

Positive reinforcement training to enhance the voluntary movement of group-housed sooty mangabeys (Cercocebus atys atys)

Positive reinforcement training (PRT) has successfully been used to train diverse species to execute behaviors helpful in the everyday care and wellbeing of the animals. Because little information is available about training sooty mangabeys (Cercocebus atys atys), we analyzed PRT...

The influence of observer presence on baboon (Papio spp

A common method for collecting behavioral data is through direct observations. However, there is very little information available on how a human observer affects the behavior of the animals being observed. This study assesses the effects of a human observer...

The relationship between socio-sexual behavior and salivary cortisol in bonobos: tests of the tension regulation hypothesis

Bonobos are known for their pacifistic behavior and their large repertoire of behaviors that are thought to serve conflict resolution. One is an unusual form of ventro-ventral mounting that facilitates genital contacts (GC). Various hypotheses have been proposed to explain...

Space use as an indicator of enclosure appropriateness: A novel measure of captive animal welfare

Empirical measures of animal behavior and space use within the captive environment can provide critical information about animals' requirements, preferences and internal states. Chimpanzees showed significant differences in how they used structural elements (P = 0.021), mesh barriers (P =...

Assessment of efficacy of three types of foraging enrichment in rhesus macaques (Macaca mulatta)

Rhesus macaques housed indoors in captivity commonly display abnormal behaviors that are rarely seen in their wild counterparts. These behaviors include stereotypic behaviors and self-abuse. These behaviors are often seen as signs of poor welfare, due to stressors in the...

Risk factors and remediation of self-injurious and self-abuse behavior in rhesus macaques

Considered signs of decreased welfare--abnormal behaviors such as self-injury and self-abuse among nonhuman primates housed in the laboratory--may put into question the validity and reliability of scientific research using these animals as models. Providing environmental enrichment decreases the incidence of...
