Research

Overview

My research group is approaching the study of dispersal in a variety of ways: from practical field ecology trapping or tracking insects and plants, to purely theoretical approaches. My research has focussed on the evolution of dispersal strategies. Generally, dispersal is favoured when kin competition is strong and habitat is widely distributed, and selected against when suitable habitat is highly aggregated in space, although intelligent organisms, able to detect suitable habitat will be more dispersive. I have been applying models of dispersal evolution to questions of range expansions and invasions including the spread of human diseases. Models demonstrate that dispersal increases at range margins providing climate has made habitat suitable beyond the range, but that range expansion is slowed by an Allee effect. Further expansion of my research considers ageing in relation to dispersal, showing how suicide genes can arise, and the effect of inter-specific interactions.

Discoveries

We have discovered that programmed death can be selected for in viscous populations.

Projects

  • The diversity of natural communities of arbuscular mycorrhizal fungi: niche or neutral model? (joint with Alastair Fitter & Thorunn Helgason) ( Funding body: NERC)
  • The genetics, ecology and evolution of ageing (joint with Steve Sait (Leeds) et al.) (Funding body: White Rose Network)
  • fishACE (joint with Jon Pitchford, York; Ulf Deickman, IASA et al.) (Funding body: EU, Marie Curie)
  • Linking population and genetic changes during range shifts induced by climate change. (joint with Chris Thomas, Roger Butlin, Sheffield & John Bridle, Bristol) (Funding body: UKPopNet)
