Accuracy of smartwatches for measuring heart rate and oxygen saturation in cynomolgus macaques compared to clinical standards

Continuous monitoring of physiological parameters in non-human primates (NHPs) necessitates a precise, non-invasive, and convenient method. This study aimed to validate the use of smartwatches with integrated pulse oximetry and heart rate (HR) monitoring capabilities for use in NHPs. Currently,...

Five-domain-based evaluation of environmental enrichment in Japanese macaques (Macaca fuscata) to reduce aggressive behavior

Compared with wild troops, Japanese macaques (Macaca fuscata), which are commonly housed in cage-like enclosures in zoos and laboratories, face limited feeding opportunities, leading to intense competition and frequent aggression. Such aggression often results in injuries, highlighting the need for...

Review of depressive-like behaviours in some group-living mammals

Thanks to animal models of depression, we are getting closer to understand the nature of this disorder in humans – but depressive disorders may not be specific only to humans. Although due to the inability to collect a verbal report...

Influence of multiple factors on rhesus macaque (Macaca mulatta) use of a feeding enrichment device

We studied the effect of different filler items on rhesus macaques’ use of a feeding enrichment device called the ‘browsing bowl.’ We examined use of the device as affected by calories, sugar content, and volume of different fillers as well...

The use of infra-red thermography to study emotions of wild crested macaques (Macaca nigra) in their natural habitat

Infra-red thermography (IRT) has been validated across a range of taxa as a non-invasive method to quantify physiological changes (variation in skin temperature) that serve as a proxy for emotional arousal in humans and other animals. While its effectiveness has...

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...

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...
