Mink (Mustela vison) is a terrestrial species high in the food chain that readily bioaccumulates environmental pollutants, and as such is considered a sensitive indicator of ecosystem health. This report describes the first year of a study to examine levels of organochlorine & heavy metal contaminants in mink along the Mackenzie River drainage basin. Mink carcasses were collected from Inuvik, Fort Good Hope, and Fort Rae during winter 1991-92 and analyzed for a suite of 63 organochlorine residues in fat & liver samples and residues of ten heavy metals in liver & kidney samples. Carcasses were also examined for sex, age, & body condition in an attempt to link contaminant levels to population effects. Results are compared to those from other mink studies in North America.

Summarizes American marten (Martes americana) harvest trends and analysis of the fourth year of a carcass collection program, conducted in the Sahtu region of the Northwest Territories during 1991-92.

Report summarizing lynx (Lynx canadensis) harvesting trends, and ongoing research programs conducted during 1991-92 in the Northwest Territories. Results of carcass collections, pelt measurements, snowshoe hare indices, and a live-trapping and radio-collaring study are given.

Masters thesis. Results of a study of a population of breeding gyrfalcons (Falco rusticolus) from 1982 to 1986 on the Kilgavik study area in the central arctic of the NWT.

Report on osprey (Pandion haliaetus) nests on Northern Canada Power Commission transmission lines supplying Yellowknife, Northwest Territories. The nests were placed on rised platforms to prevent power outages which resulted in fewer outages and retention of preferred nesting locations.

Report of a transect survey carried out in 1983 north of Great Bear Lake in the Northwest Territories to obtain an estimate of the numbers of muskoxen (Ovibos moschatus) (total 1880).

Report of a study conducted in 1983 and 1984 of the ecology (nest sites, number of young produced, mortality rates, food sources, potential competitors) of gyrfalcons (Falco rusticolus) in the Central Arctic, Northwest Territories.
