Behavioral Biology of Laboratory Animals

This 30-chapter volume informs students and professionals about the behavioral biology of animals commonly housed in laboratory and other captive settings. Each species evolved under specific environmental conditions, resulting in unique behavioral patterns, many of which are maintained in captivity...

Evaluating the co-occurrence of abnormal behaviors in chimpanzees (Pan troglodytes)

For decades, welfare scientists have focused on investigating and mitigating the abnormal behaviors—including repetitive stereotypic behaviors and abnormal stances/postures—displayed by chimpanzees residing in professionally managed settings. In an effort to design feasible and practical welfare assessments, researchers often pool abnormal...

Minimally invasive electrocorticography (ECoG) recording in common marmosets

Background: Electrocorticography (ECoG) provides a valuable compromise between spatial and temporal resolution for recording brain activity with excellent signal quality, crucial for presurgical epilepsy mapping and advancing neuroscience, including brain-machine interface development. ECoG is particularly effective in the common marmoset...

Development of a non-invasive novel individual marmoset holder for evaluation by awake functional magnetic resonance brain imaging

Background: Although functional MRI (fMRI) in awake marmosets (Callithrix jacchus) is fascinating for functional brain mapping and evaluation of brain disease models, it is difficult to launch awake fMRI on scanners with bore sizes of less than 16 cm. A universal...

Physiologic consequences of housing adult male cynomolgus monkeys (Macaca fascicularis) in heterosexual pairs: A pilot study using implanted biotelemetry

Facilities may forgo attempting to socially house adult males due to fear of animal injury, study disruptions, and confounding data results. To leverage the potential advantages of male–female pairs, and to understand the impact on measures typically used in safety...

A computational model to support the welfare-based management of a laboratory colony of common marmosets

Here, a computational model to forecast the population dynamics of a laboratory colony of common marmosets (Callithrix jacchus) is presented. This tool supports decision-making that seeks to maximize welfare and maintain a healthy and genetically diverse colony. The model considers...

Should zoo food be chopped for ruffed lemurs? It’s not so black and white

Whole food diets in zoos have the potential to reduce microbial contamination and keeper preparation time, whilst also reducing food nutrient breakdown. Given these benefits, it is important to determine whether there is any value in chopping up food. Lemurs...

Cortisol and catecholamine concentrations are affected by repeated relocations of adult female rhesus monkeys (Macaca mulatta)

In captive primate facilities, relocations—moves, within the facility, from one cage to another—can be common events. On the one hand, relocations are generally regarded as relatively benign events, as past studies have generally shown only transient elevations in cortisol concentrations...

The provision of browse and its impacts on the health and welfare of animals at the zoo: A review

Browsers are animals that consume significant proportions of leaves, twigs, and bark from woody plants. These species have evolved morphological, physiological, and behavioral adaptations to subsist on a specialized diet. In zoos and other managed care facilities, the provision of...
