Principal Investigator: Olsen, Sue K.
Licensed Year(s): 1992
Summary: The experiment will determine the interacting effects of fire severity, soil moisture and air temperature treatments on the emergence, winter survival and initial growth of treeline and near treeline tree species. The availability and viability of tree seed for successful regeneration of the treeline and near-treeline tree species will also be determined....

Principal Investigator: Landhaeusser, Simon M.
Licensed Year(s): 1992 1991 1990
Summary: To determine the maximum size of treeline tree species in a burned and unburned valley in the Caribou Hills, the mass of standing trees on different slopes and aspects will be estimated and related to the energy input. In 1992 the plots prepared in 1990 and planted and seeded in 1991, will be revisited and measurement of growth for the second growing season will be taken....

Principal Investigator: Nicholson, Barbara
Licensed Year(s): 1992
Summary: The Researcher will map the present distribution of boreal and subarctic wetlands in the Mackenzie River Basin. Wetland vegetation and water chemistry will be described for areas immediately surrounding permanent weather stations. The ecological relationships between climate, wetland water chemistry and wetland species distribution will be analyzed. A predictive indicator model will be built to pr...

Principal Investigator: Slocombe, D. Scott
Licensed Year(s): 1991
Summary: To provide a basis for planning and management of the Pingo Canadian Landmark site, required by the Inuvialuit Final Agreement, the researchers will identify the significance of the biophysical, cultural and economic resources....

Principal Investigator: Squires Taylor, Cindy
Licensed Year(s): 1992 1991
Summary: The Researcher will conduct a survey, approximately 30 km on either side of the Mackenzie River using satellite imagery. A classification will be undertaken of the area from the Mackenzie Delta to the Fort Simpson area, with wider zones along the east side to include proposed pipeline routes. The information can be plotted as colour maps to show the location of trap lines, forest fires or wildlife...

Principal Investigator: DeBruyn, Adrian
Licensed Year(s): 1992 1991
Summary: The Researcher will investigate the biology of predaceous insects in terrestrial and freshwater habitats. An inventory of predaceous insects will be conducted through trapping and collecting. Their prey and habits will also be identified....

Principal Investigator: Cosens, Susan
Licensed Year(s): 1990
Summary: The Researcher and team will apply new tag technology and DNA analysis to a study of site tenacity and industrial disturbance of bowhead whales. They will test the feasibility of using sonic tags to track bowheads underwater and will be testing sampling methods for collecting skin from live whales for DNA analysis....

Principal Investigator: Sandstrom, Steve
Licensed Year(s): 1990
Summary: The Fieldwork will involve removing fish from selected pools by a number of methods including electroshocking, seine and angling. They will be anaesthetized, weighed, measured and tagged. The researcher estimates that no more than 5% of the total catch will be dead sampled....

Principal Investigator: Eggertsson, Olafur
Licensed Year(s): 1990
Summary: The Researcher will sample about 100-200 driftwood logs using a chain-saw to cut off a 1-2 cm plate about 0.5 m inside the end of each log. The material will be shipped to Lund University laboratory for examination....

Principal Investigator: Wein, Ross
Licensed Year(s): 1993 1992 1989 1988 1987
Summary: In the early 1970's, several test plots were established to see what happens when the plants and soil are disturbed or removed by fire, oil spills, and vehicles. Dr. Wein and two students will be re-visiting these sites to document how the plants have recovered since that time....
