Environment Adaptation in Arctic Aquatic Organisms
Principal Investigator: Ballantyne, James
Licensed Year(s): 2000
Summary: This project will examine the adaptation of freshwater fish to low temperatures. The data to be collected includes blood and tissue samples from fish. These samples will be analyzed for enzymes, fats and proteins. These results will be compared to samples taken from other locations (e.g. Nunavut, southern waters). This work will provide important information relating the sensitivity of Arctic ...


Studies on the past, present and future ecological impact on Canadian northern boreal forest and arctic ecosystems due to mining activities, shown at the Great Slave Lake area, Northwest Territories, Canada
Principal Investigator: Steinecke, Karin
Licensed Year(s): 1998 1997
Summary: The project will focus on understanding, analyzing and evaluating the reactions of the northern boreal forest ecosystems in the Great Slave Lake region due to man made stress of mining, settlement and connecting activities. The project will try to develop some general conclusions, statements and model systems. The research team (2 persons) will come from Europe to Yellowknife by plane. The base wi...


The molecular population genetics of the arctic-alpine ground-beetle species Amara alpina
Principal Investigator: Schwert, Donald P.
Licensed Year(s): 1995 1992
Summary: The sample of arctic-alpine ground-beetles will be collected under rocks and by pitfall traps (dixie cups placed in 8 cm diameter drilled holes) in the tundra habitat. All rocks will be replaced exactly and pitfall trap holes refilled with their soil plugs. No chemicals will be used in any of the trapping or collecting. Specimens will be analysed using DNA techniques which include RLPF's and PC...


Mosquito Baseline Study for the City of Yellowknife
Principal Investigator: Ellis, R.A.
Licensed Year(s): 1993
Summary: The mosquito baseline study is aimed at determining which mosquito species breed in and around Yellowknife. While sampling for mosquito larvae, samples of non-target (i.e., other) insect species will also be taken to determine which of these species are natural predators or parasites of mosquitoes, or should be protected for other reasons. The City of Yellowknife will be provided with recommenda...


The Implications of Climate Change for Fish and Wildlife Resources in the Mackenzie Basin
Principal Investigator: Brotton, Janet
Licensed Year(s): 1993
Summary: The proposed research will investigate the implications of climatic change for fish and wildlife resources in the Mackenzie River Basin. A computer model will be used to predict temperature and precipitation changes associated with an expected doubling of carbon dioxide concentrations. Data points used in the modelling exercise will correspond to selected weather stations in the region. The res...


Genetic Variation and Population Structure in Boreal and Subarctic Mire Sedges (Carex, Cyperaceae)
Principal Investigator: Waterway, Marcia J.
Licensed Year(s): 1990
Summary: The Researcher and her team will sample approximately twenty different species of sedges in a range of wetlands between Edmonton and Yellowknife. They will find out the range of conditions in which each species grows best and will determine whether broad tolerance results from inherited variability or from the ability of individuals of each species to tolerate different conditions....


Systematic studies of the lichen genus "Ionaspis" in North America
Principal Investigator: Brodo, Irwin
Licensed Year(s): 1988
Summary: Dr. Brodo and two students (Mr. Lutzoni and Mr. Proulx) will be collecting and identifying lichens from different parts of the NWT. If there are differences, they want to know why....


Treeline plant population response to postglacial climatic change in North Central Canada.
Principal Investigator: MacDonald, Glen M
Licensed Year(s): 1987
Summary: To use fossil pollen and plant macrofossils from small lakes to reconstruct the response of plant populations in the treeline zone to climatic change. Modern pollen surface samples from small lakes in the treeline zone will be collected to aoid in the interpretation of the fossil pollen samples. The study area will include the boreal forest, forest-tundra and tundra zones near Yellowknife (115 W...


Jack Fish Lake - Arctic Char Feasibility Study
Principal Investigator: Davis, Stuart
Licensed Year(s): 1987
Summary: To determine the feasibility of Arctic Char stocking in Jack Fish Lake, for a commercial scale farm and hatchery and to determine the economic and nutritional costs and benefits of foods derived from local fish silage versus imported commercially prepared feeds....


Licence #7001
Principal Investigator: Zallen, Morris
Licensed Year(s): 1987
Summary: To identify key biological resources (principally migratory birds and mammals) and aspects of human land use (communities and settlements, resource harvesting areas) within or adjacent to proposed flight corridors. Potential concerns related to the above will be addressed by assessing the degree of disturbance from noise & emissions from aircraft. This research includes gathering socio-economic ...
