Ben undertakes research focussed on understanding how changing environmental pressures result in faunal transformation over time, addressing how best to monitor biodiversity change, how to understand the nature of the winners and losers of those changes, and how to predict future outcomes.  His research is broad, spanning the development of ecological theory, through to applied questions concerning the measurement, prediction, impacts and consequences of pressures on biodiversity.
