Current Research

My research touches on a variety of themes including conservation prioritization, invasion ecology, biogeography and spatial statistics. I have a particular interest in practical questions regarding invasive species control and management to protect threatened species. My work in these areas aims to provide conservation agencies with useful tools that allow them to achieve better results within their limited budgets. I also look at theoretical questions regarding coexistence in fluctuating environments, methods for quantifying biodiversity, and the determinants of community assembly. My study systems include polar regions, temperate grasslands and lakes, and tropical forests.

Recent research questions include the following:

  • What lessons can be shared between Arctic and Antarctic scientists to enhance environmental conservation?
  • What benefits do conservation programs for charismatic ‘flagship’ species have for other species, and can we increase these benefits?
  • What are the determinants of invasive species abundance in fragmented grasslands?
  • Can we make sampling programs for environmental assessment more efficient?
  • What are the best ways of numerically comparing biodiversity patterns among regions?
