Heart rate (HR) and respiration rate (RR) play an important role in the study of complex behaviors and their physiological correlations in non-human primates (NHPs). However, collecting HR and RR information is often challenging, involving...
Environmental enrichment aims to enhance primate wellbeing by providing physical and mental stimuli to address the biological and psychological needs of individuals. However, lack of knowledge regarding the development of enrichment research hampers implementors and...
Primates are important species for biomedical research and ensuring their good welfare is critical for research translatability and ethical responsibility. Systematic animal welfare assessments can support continuous programme improvements and build institutional awareness of areas...
Environmental enrichment is frequently used to improve the captive environment, aiming to enhance the quality of captive animal care. Water-based enrichment can increase exploratory behaviour and tool use, promoting object manipulation, particularly in macaque species...
Light enables vision and exerts widespread effects on physiology and behavior, including regulating circadian rhythms, sleep, hormone synthesis, affective state, and cognitive processes. Appropriate lighting in animal facilities may support welfare and ensure that animals...
Human evaluation of animal emotional expressivity can inform animal welfare. Qualitative Behavioural Assessment (QBA) has been applied to domesticated and some non-domesticated animals, but its use in primates is limited despite their emotional expressivity. We...
Over the past few decades, the concept of animal welfare has become increasingly prominent in Western societies. Faced with this collective awareness, various organisations are now making it a point of honour to consider the...
Vervet monkeys (Chlorocebus pygerythrus) are considered pests by farmers and homeowners. Consequent attempts to exterminate problem adult vervet monkeys often result in orphaned young offspring, which are sometimes taken to wildlife rehabilitation centers. We assessed...
Assessing quality of life in animals is an art as much as a science. Despite the use of questionnaires and keeper reports which consider several aspects of well-being, the process often remains subjective. Keepers have...
Keystone individuals are expected to disproportionately contribute to group stability. For instance, rhesus macaques (Macaca mulatta) who police conflict contribute towards stability. Not all individuals’ motivations align with mechanisms of group stability. In wild systems...
