Abnormal/Problematic Behavior

Personality predicts the responses to environmental enrichment at the group but not within-groups in stereotypic African striped mice, Rhabdomys dilectus

Environmental enrichment is used to enhance the well-being of captive animals and to prevent or reduce stereotypic and other abnormal behaviours. However, environmental enrichment does not always succeed in its intended purpose. We investigated whether personality (i.e. consistent individual variation...

Abnormal repetitive behaviours in captive birds: A Tinbergian review

Abnormal repetitive behaviours (ARBs) are associated with past, or present, welfare problems and are common elements of the behavioural repertoire of some captive animals, including birds. Millions of birds from hundreds of species are held in various captive settings, yet...

Rhesus macaques (Macaca mulatta) displaying self-injurious behavior show more sleep disruption than controls

Self-injurious behavior (SIB) is a pathology observed in both humans and animals. In humans, SIB has been linked to various mental health conditions that are also associated with significant sleep disruption. In rhesus macaques, SIB consists of self-directed biting which...

A cross-species comparison of abnormal behavior in three species of singly-housed old world monkeys

Abnormal behavior occurs in a number of captive nonhuman primate species and is often used as an indicator of welfare. However, reported levels of abnormal behavior often vary across species, making general welfare judgments difficult. The purpose of this study...

Decreased environmental complexity during development impairs habituation of reinforcer effectiveness of sensory stimuli

Previous research has shown that rats reared in simple/impoverished environments demonstrate greater repetitive responding for sensory reinforcers (e.g., light onset). Moreover, the brains of these rats are abnormally developed, compared to brains of rats reared in more complex/enriched environments. Repetitive...

Hair plucking, stress, and urinary cortisol among captive bonobos (Pan paniscus)

Hair plucking has been observed in many captive primate species, including the great apes; however, the etiology of this behavioral pattern is poorly understood. While this behavior has not been reported in wild apes, an ethologically identical behavior in humans,...

Assessing significant (>30%) alopecia as a possible biomarker for stress in captive rhesus monkeys (Macaca mulatta)

Hair loss is common in macaque colonies. Very little is known about the relationship between psychological stress and hair loss. We initially examined alopecia and hair cortisol concentrations in 198 (89 male) rhesus macaques from three primate centers and demonstrated...

Prior facility affects alopecia in adulthood for rhesus macaques

Alopecia has proven to be a persistent problem for captive macaques; many cases continue to elude explanations and effective treatments. Although almost all captive populations exhibit alopecia rates higher than those seen in the wild, there also appear to be...

Differential relationships between chronic hormone profiles in pregnancy and maternal investment in rhesus monkey mothers with hair loss in the neonatal period

Hair loss is commonly used as an indicator of well being in primate facilities, yet it has been shown to also occur in otherwise healthy pregnant and postpartum females. There is significant variability in the incidence of hair loss during...
