Main research fields: zoology and reproductive physiology specialization fields: Animal reproduction, Behavioural ecology, Behavioural physiology, sociobiology. My research interests focus mainly on the sociobiology of African rodent moles (Bathyergidae) and in particular the extrinsic and intrinsic factors that have led to the evolution of sociality in this remarkable endemic African family. My research group is fundamentally interested in elucidating the modes and mechanisms that are responsible for reproductive suppression in the non-reproductive females of the various species. Research is currently being directed at the neuroendocrine and molecular levels to elucidate the extent, nature and location of GnRH suppression. We are also interested in the photic and thermic input in the control of reproduction in seasonally reproducing mole-rats and the potential lack of a role in aseasonally breeding bathyergids. Long term population studies on social mole-rats from mesic and xeric environments are underway. These studies are providing empirical data on the spatial distribution of colonies, longevities, factors restricting and promoting dispersal, vagility, foraging methods and lifetime reproductive success. We are interested in the genetic relatedness of colonies and also the type of paternal skew operational in the social genera. This work is being carried out in collaboration with Dr Chris Faulkes at Queen Mary and Westfield College, London.
