Principal Investigator: Aiken, Susan
Licensed Year(s): 1993 1992 1991
Summary: The researcher will continue her study on NWT grasses. She will collect living plants in order to conduct chemical analyses on the plant tissue. These tests will help to identify different species of grasses (especially those that look very similar) and also help to determine where these species originated from. In addition, the researcher has small experiments on grass being conducted by staff...

Summary: This study will address the impact that muskoxen are having on sedge meadows (the habitat that is important for their survival in the Thomsen River valley). In this study, I will examine the response of sedge meadow plants to the effects of grazing by muskoxen. I will monitoring the growth and chemical makeup of plants in 3 situations: (1) unprotected plots subject to muskoxen grazing; (2) artif...

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: Romo, J.T.
Licensed Year(s): 1992
Summary: The project examines the effects of a high-density muskoxen populations on a sedge meadow plant community. Two fences exist at the study site to exclude muskoxen and thus provide an ungrazed area used for comparison with the grazed area. Plant species abundance, plant height, grazing use of plant species and weight of plants are some of the data that will be compared among grazed and ungrazed are...

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: Comtois, Paul
Licensed Year(s): 1991
Summary: The Researcher will study the behavior of pollinating insects (bees) in ecosystems dominated by plants of the blueberry family (Ericacees). They will investigate competition between flowering plants syncronized for the same insect pollinators. Most of their work will be conducted on Herschel Island. Minimal study will be conducted near Tuktoyaktuk near their base camp at Polar Continental Shelf Pr...

Principal Investigator: Scotter, George
Licensed Year(s): 1990
Summary: The Researcher and team will carry out this survey at the request of the community of Paulatuk. They will summarize the existing knowledge of the natural resources of the Bluenose Lake Region. A total of about 20 stops will be made to examine the vegetation, soil, wildlife and physiogeography and to collect plant and soil samples....

Principal Investigator: Harmsen, R.
Licensed Year(s): 1991 1990
Summary: The Researcher and his team will collect data on plant size, flowering, seed production, survival and for greenhouse germination experiments. Wire enclosures set up in the previous summer will be remapped....
