Effects of sociality on parasitism: transmission and susceptibility in a sifaka (Propithecus verreauxi) population

Summary
 
 
In group-living animals, individuals are exposed to various health-related costs and benefits of sociality. In this project, we combine long-term fitness data and detailed data on social behavior of a Malagasy primate species (Verreaux’s sifaka, Propithecus verreauxi) with data on social contact and parasitism to examine the social transmission of parasites within and between groups, which constitutes one major cost of group-living. This project has two specific goals. First, we will expand our knowledge of parasites in a wild population of this primate, based on a combination of invasive and non-invasive sampling. We will determine prevalence, species richness and estimate infection intensity for selected parasites (bacteria, viruses, endo- and ectoparasites) with different transmission modes. Second, we will combine detailed behavioral data on different types of social contacts from individuals of 8 social groups to generate population-wide social networks, which serve to test various hypotheses about social and ecological factors in parasite transmission. In addition, empirical data will be used to model social transmission of parasites. We will also initiate establishment of methods that will allow assessment of individual condition, genetic constitution and stress in a follow-up project. Together, these data will contribute to a comprehensive understanding of the relative importance of intrinsic, ecological and social factors in generating fitness variation that does currently not exist for any non-human primate species.
