Sociality and health in lemurs

Strong links between sociality and fitness have long been identified in humans and non-human primates. For example, socially well-connected individuals enjoy substantially greater longevity, whereas socially stressed or isolated individuals suffer fitness costs. However, the proximate mechanisms mediating these positive or negative effects remain largely unexplored. Here we examine the relative importance of social factors, how exactly social roles and networks affect susceptibility to disease, how social stress mediates and modulates these links, and how social factors determine the transmission of health-relevant micro-organisms in lemurs.

These projects are part of the research group ‘Sociality & Health in Primates’ funded bei the DFG.
