Canadian Intersite Decomposition Experiment
chercheur principal: Wein, Ross
Année(s) de permis: 1993
Résumé: Forestry researchers tend to study in detail their local forests yet for major issues such as global warming, it is necessary to conduct research over larger areas to understand impacts on Canadian forests and industry. This study attempts to better describe rates of decomposition and nutrient mineralization across Canadian forests in order to understand how forests are supplied with nutrients fo...

The Broad Whitefish Traditional Knowledge Ecological Study
chercheur principal: Freeman, Milton M.R.
Année(s) de permis: 1994 1993 1992
Résumé: Under the direction of the Aklavik and Inuvik HTA's, the research team will carry out interviews with Inuvialuit that are knowledgable about the broad whitefish and its fishery in the local waters. Data to be obtained include information on the traditional fishery, changes to this fishery, knowledge about the breeding and feeding habits, migrations, parasites and diseases, and effects of local en...

Electrophoretic Studies of North American Halictid Bees
chercheur principal: Taylor, John S.
Année(s) de permis: 1992
Résumé: The researcher and his team will collect specimens of bees that belong to the subgenus Evylaeus (Family Halictid), which are small "ant-like" bees sometimes called "sweat bees." The researcher would like to determine how they are related to the European species, which, unlike the Evylaeus, are social in their behaviour. This study may shed some light on the evolution of social behaviour in bees....

Fire Severity and Growth of Treeline Tree Species: Climate Change Implications
chercheur principal: Olsen, Sue K.
Année(s) de permis: 1992
Résumé: 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....

Climatic Change at the Forest-Tundra Boundary
chercheur principal: Landhaeusser, Simon M.
Année(s) de permis: 1992 1991 1990
Résumé: 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....

Statement of Significance and Resource Description and Analysis for Pingo Canadian Landmark
chercheur principal: Slocombe, D. Scott
Année(s) de permis: 1991
Résumé: 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....

The Biology of Predaceous Insects in the Canadian Arctic
chercheur principal: DeBruyn, Adrian
Année(s) de permis: 1992 1991
Résumé: 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....

North Slope Char Summer Ecology Project
chercheur principal: Sandstrom, Steve
Année(s) de permis: 1990
Résumé: 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....

Re-evaluation of Disturbance Experiments in the Lower Mackenzie Region, NWT
chercheur principal: Wein, Ross
Année(s) de permis: 1993 1992 1989 1988 1987
Résumé: 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....

Influence of season and latitude on the fatty acid composition of great northern pike
chercheur principal: Schwalme, Karl
Année(s) de permis: 1988
Résumé: Karl Schwalme wants to know how and why the fat content of pike changes during the year. He will collect about 30-50 great northern pike from each lake by using a 2 1/2 inch gill net which will only be set during the day. He will then take the fish back to the Inuvik Research Centre to determine their fat content. Since some of the fats help to prevent heart disease in people, the annual change ...
