Positive reinforcement-based magnet training permits social housing in catheterized squirrel monkeys

Background: Non-human primates play a critical role in neuroscience research. Though they are social animals, laboratory study requirements can sometimes require single housing and thereby prevent social housing. New Method: To eliminate single housing and promote well-being within our squirrel...

Pairing laboratory-housed adult male rhesus macaques (Macaca mulatta): Success rates in relation to behavioral response and duration of visual contact

While the benefits of pair housing have been well documented, less is known about increasing success in adult male macaque pair introductions. In this retrospective study, 95 unfamiliar adult male macaque (Macaca mulatta) pairs were examined to determine whether duration...

The impact of care on chimpanzee welfare: A comprehensive review

Animal welfare research has increased dramatically in scope and prevalence, spanning zoos, aquariums, sanctuaries, and research facilities. Chimpanzees are the most common and well-studied great ape living in human care. This considerable focus on chimpanzee welfare provides the foundation for...

Effect of rehabilitation exercise on locomotion performance of captive Bengal slow loris

The Bengal slow loris (Nycticebus bengalensis) is one of the most confiscated and rescued primate species in China. These animals are often subject to physical issues due to poor husbandry practices in captivity. Many individuals rescued from the illegal wildlife...

The lasting impact of social isolation: Behavioral insights from former pet and entertainer chimpanzees in a sanctuary in Spain

Human fascination with chimpanzees has driven extensive research on the species, but also led to exploitation by private owners and entertainment industries. These animals often suffer species-specific inadequate conditions, which can result in the development and display of abnormal behaviors...

Salivary cortisol captures endocrine response to an acute stressor in captive female tufted capuchin monkeys (Sapajus apella)

Measuring glucocorticoids such as cortisol is a useful tool for exploring relationships among behavior, physiology, and well-being in primates. As cortisol circulates in blood, it moves into biological matrices such as hair, urine, feces, and saliva. Saliva sampling is a...

No effect of infant nursery rearing on laboratory rhesus monkey dams’ social behavior or long-term cortisol profiles

While the behavioral and physiological impacts of nursery rearing in laboratory-housed infant monkeys have been well characterized, to date no studies have examined the impact on nonhuman primate dams of their infants being removed for rearing in the nursery. Despite...

Deep learning for face detection and pain assessment in Japanese macaques (Macaca fuscata)

Facial expressions have increasingly been used to assess emotional states in mammals. The recognition of pain in research animals is essential for their well-being and leads to more reliable research outcomes. Automating this process could contribute to early pain diagnosis...

The use of guanfacine to mediate anxiety-related reactivity and reduce associated agonistic behavior in two pigtail macaques (Macaca nemestrina)

Guanfacine, an α2-adrenoceptor agonist, has been used to successfully treat self-injurious behavior in nonhuman primates, including macaques (Macaca mulatta) and baboons (Papio anubis). It does so by facilitating a correction to the dopaminergic system that mediates a reduction in impulsivity...
