For female mice, increased complexity of space is more important than the quantity of space.

Combination therapy reduces self-injurious behavior in a chimpanzee (Pan troglodytes): A case report

The combination therapy approach entailed the following (a) pharmacological intervention with a gamma-aminobutyric acid (GABA) analogue, (b) positive reinforcement training, and (c) environmental enrichment, as well as social and environmental modification. The individually tailored, multifaceted combination therapy resulted in the...

Maladaptive behaviors: Stereotypical behavior; hair pulling-and-eating and alopecia (hair loss); self-injurious biting

Animals kept in legally minimum-sized, unstructured enclosures very often exhibit stereotypical behaviors. Traditionally, these repetitive movement patterns without obvious goals or functions are categorized as abnormal. A healthy animal kept in a small, barren enclosure has little choice of expressing...

Refuge cover decreases the incidence of bite wounds in laboratory south african clawed frogs (Xenopus laevis)

The Guide for the Care and Use of Laboratory Animals recommends environmental enrichment for all laboratory animals, including amphibians. In this study, we evaluated the effect of adding environmental enrichment in the form of acrylonitrile- butadiene-styrene (ABS) pipes as covered...

Self-injurious behavior in rhesus macaques: early history and present factors and the role of the serotonin system

Self-injurious behavior (SIB) is a problem of virtually all nonhuman primate research facilities. Its incidence varies between institutions and with the strictness of the criteria that are used. Nevertheless, it is widely agreed that several variables are important for determining...

Alterations in the serotonin system of monkeys exhibiting self-injurious behaviors

Self-injurious behavior (SIB) presents a serious problem in laboratory macaques that cannot be socially housed for scientific reasons. Pharmaceutical treatments that alter the serotonin (5HT) system have sometimes proven effective in alleviating SIB in both human patients and macaques. We...

Abnormal behavior as a factor of compliance with positive reinforcement training for singly-housed adult rhesus macaques (Macaca mulatta)

Positive reinforcement training is an important element of behavioral management programs for nonhuman primates. However, more empirical information is needed to determine whether animals identified for intervention will engage in such training, affecting the amount of personnel time and other...

Fluoxetine dose finding study for treatment of self-injurious behavior in Macaca mulatta

Based on clinical efficacy in the short-term treatment of self-injurious behavior in macaques, we performed a dose-finding study to establish optimal doses of fluoxetine (selective serotonin reuptake inhibitor). The subjects were 11 male (aged 7 – 15 years) rhesus macaques...

Alopecia and overgrooming in laboratory monkeys vary by species but not sex, suggesting a different etiology than self-biting

Alopecia in laboratory monkeys can result from overgrooming (OG), medical conditions, or hormonal variation. Because hair loss is visible, disproportionate intervention may be expected relative to other indicators of potentially compromised well-being. Two analyses (α=0.05) suggest that alopecia and overgrooming...

Why and how should we use environmental enrichment to tackle stereotypic behaviour?

This paper summarises recent findings on the causation of stereotypic behaviours and other abnormal repetitive behaviours (ARBs) in captive animals: primarily motivational frustration and/or brain dysfunction, with possible contributory roles also being played by habit-formation and ‘coping' effects. We then...
