Project summary
For group-living vertebrates, play and grooming have a number of facets that could be potential indicators of positive welfare, but analysis of such behaviors are yet to be put into a formal framework for monitoring wild animal populations. The Middle Atlas region of Morocco hosts one of the largest populations of wild Barbary macaques, an endangered primate species. These animals face a number of environmental challenges that may disrupt positive social experiences, including anthropogenic disturbance, threats from natural and introduced predators, and an extreme climate. Focusing on six different macaque groups with variable group sizes and facing varying degrees of human exposure, this pilot project will use play and grooming behavior to quantify social time allocation, emotional contagion/synchronization, and social attention as potential assays of positive welfare. As human exposure is typically associated with poor health outcomes in wild animals, this pilot project will focus on this specific environmental challenge to help validate our assays, which can later be applied to examine how positive welfare varies across different gradients, such as climate change or variation in predator pressure.
Why we funded this project
Most animal welfare research is focused on minimizing suffering, but it’s also vital to maximize positive experiences. The links between positive welfare and evolutionary fitness are also less obvious than for negative welfare, where factors like poor health seem to be associated with both poor welfare and low evolutionary fitness. Because more research focuses on fitness than welfare, the unclear relationship between fitness and positive welfare has contributed to the neglectedness of indicators of positive welfare. This project was one of the few we received that addressed the theme of positive welfare, and we hope that this pilot in primates will provide information to support similar studies in other social species.
