Soil-Vegetation-Atmospheric Interactions as Influenced by Hydrologic Conditions in Northern Ecosystems
The primary objective of this research initiative is to assess the state of greenhouse gas source/sink strength and evapotranspiration losses of terrestrial ecosystems in the Canadian Subarctic and Boreal zones to understand the mechanisms that control the greenhouse gas balance (especially carbon) so that we can predict their potential fate under a changing climate. The research proposed here focuses on CO2, CH4 and N2O primarily, and takes the geograhical focus of the Boreal Forest to Subarctic Tundra transition zone, as this is the region expected to experience the most rapid response to any climatic variability. The measurement techniques and sampling strategies here range in scale from chamber to micrometeorological flux tower. Done in collaboration with Dr. M. English (Wilfrid Laurier University), Dr. P. Lafleur (Trent University), Dr. P. Grogan (Queen’s University) and Dr. G. Henry (University of British Columbia). Current collaborations include Dr. W. Quinton (Wilfrid Laurier University), Dr. B. Wolfe (Wilfrid Laurier University) and Dr. S. Carey (Carleton University).
