Our research explores the evolutionary causes and ecological consequences of animal societies and breeding systems and the mechanisms underlying contrasts in reproduction and behaviour.  We work principally with long-term, individual-based studies of mammals, including meerkats and mole-rats in the southern Kalahari.  In addition, we maintain a breeding facility with fifty-plus captive colonies of mole-rats at the same site which is used to investigate the mechanisms controlling reproductive suppression and cooperative behaviour.

Current research topics include:

  • The extent, patterning and causes of individual variation in cooperative behaviour.
  • The determinants of fitness in breeding females in cooperative breeders.
  • The endocrinological basis of variation in reproduction and cooperative behaviour in cooperative breeders.
  • Changes in gene function during the transition of individuals from juveniles to helpers and breeding adult.
  • The measurement of selection operating between individuals and between groups in cooperative societies.
  • The reasons for the association between cooperative breeding and unpredictability of climatic factors.
  • The dynamics of social groups and their effects on individual fitness.
  • The effects of variation in rainfall and temperature on population dynamics in cooperative breeders and their interaction with Allee effects.
