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...
chercheur principal:Evans, Marlene S. Année(s) de permis:
1992
Résumé:
The Researchers will collect a series of sediment and water samples. These will be analyzed for plant nutrients, concentration of microscopic plant cells, bacteria, suspended solids, dissolved oxygen and organic contaminants. Microscopic animals will also be netted. They will determine the abundance and composition of the animals and conduct experiments to measure their feeding rates and fat cont...
chercheur principal:Kuhnlein, Harriet V Année(s) de permis:
1990
Résumé:
Dr. Kuhnlein and her team will study the foods in the traditional food system of the Dene people of Fort Good Hope/Colville Lake for their composition and patterns of use. Nutritional properties as well as toxicological properties will be assessed. Household and personal food use interviews previously collected will be analyzed using nutrient and toxicology data of food samples from the Dene area....

1988
Résumé:
To study epontic algae and amphipods in Chesterfield inlet area; to determine dynamics of Si and N as essential nutrients; to sample stomach contents of hunter-killed seals for food habit analysis....

chercheur principal:Welch, H.E. Année(s) de permis:
1980
Résumé:
A continuation of an experiment on an isolated lake to which methane gas has been added thereby simulating a break in a gas pipeline. This season, the work will concentrate on seeing the effects of artificially added nutrients to the lake. Supplementary water studies and radionuclide level determinations will also continue....

chercheur principal:Rigler, Frank Année(s) de permis:
1976
Résumé:
1) To test the applicability of the Dillon and Rigler (1974) method of predicting the trophic status of lakes in the Sub-Arctic. 2) To modify and develop this method so accuracy and precision are improved....
