Affective responses and behavioral strategies to social fusion events in zoo-housed bonobos

Species with fission-fusion dynamics may face heightened social tension during fusion events due to relationship insecurity and competition over resources. Affective consequences of such events are important determinants for behavioral responses, yet remain poorly understood. To evaluate the affective consequences...

Marm-ite moments: Enriching marmoset behaviour with the 3Rs

It is well documented that activity levels of non-human primates (NHPs) are reduced in captivity, particularly in laboratory settings where space and enclosure design are limited.1 The 3Rs encourages researchers to refine their care of protected species by increasing the...

Positive reinforcement training: Old world NHPs

Positive reinforcement training (PRT) is increasingly used to refine scientific and husbandry procedures involving Old-World nonhuman primates (NHPs) around the globe. PRT provides mental stimulation as well as reduces stress for NHPs. This will lead to better overall wellbeing and...

Using the Welfare Quality® framework to develop a welfare assessment protocol for captive chimpanzees (Pan troglodytes)

Good welfare is of inherent value to all captive animals and promotes species conservation objectives. Concern for animal welfare is growing globally, and research shows that animal welfare is a top priority for zoo visitors. There is, therefore, an urgent...

Behavioral and spatial analysis of a Symphalangus syndactylus pair in a controlled environment

For the effective management of captive animals, monitoring their behavior and interactions within the exhibit is essential. This approach provides insights into their welfare and helps identify behavioral differences compared to conspecifics in the wild. This ex situ study aimed...

From Fish to Mice to Monkeys in Research: Challenges and Opportunities for Mental Well-being

This chapter focuses mainly on animals in medical research. Many, especially the smaller species such as rat, mice, and zebrafish, may be seen only a few minutes a day by their human caregivers. Most laboratory animals are kept in confinement...

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...
