The focus of my research program is to understand the importance of spatial dynamics to communities and populations, examining ideas that are central to biodiversity maintenance and conservation.

Right now I am exploring these questions:

  1. Do traits of beetle species and their short term responses predict their extinction risk after 25 years of habitat fragmentation? Is there an extinction debt? How well does metacommunity theory describe community disassembly? This work is set within the Wog Wog habitat fragmentation experiment in south eastern Australia, which was established by CSIRO in 1985 (Collaborators Brett Melbourne, Saul Cunningham, Don Driscoll, Chris Margules, Mike Austin, John Morgan.)
  2. I am also part of NutNet (the Nutrient Network). I am examining the effect of productivity on community assembly with data from a large number of grassland sites across the globe.
