Bio

Dr. Cairns' research concentrates on the impacts of climate change on vegetation at short and long time scales in a variety of environments.  He has worked extensiviely at ecotones, the transion zones between different vegetation types.  Most of his work has been accomplished at treelines in the western United States, Alaska  and in northern Sweden.  He also has projects in two other sensitive environments: saltmarshes on the coasts of Denmark and Texas, and in tundra environments on the North Slope of Alaska.  He utilizes a variety of methods to answer questions pertinent to the response of these environments to climate change including: population genetics, dendroecological methods and simulation modeling. 

Research Projects

  • A population genetics based analysis of dispersal at alpine treeline
  • Modeling patch-scale expansion of arctic shrubs
  • Influences of herbivory on treeline under changing climate
  • The utility of salt marsh vegetation as an indicator of climate change at short and long time scales
  • Forest restoration planning and assessment for the southern pine beetle and other invasive pest species
