Summary: This study examines (1) the regeneration dynamics of White spruce in the Mackenzie Delta and Black spruce on seismic lines; (2) the potential for seeds to disperse on snow; (3) pollen dispersal; and (4) pollen production. Study sites in the Mackenzie D...

Summary: Tree-line plant species are sensitive to changes in climate. Most trees growing in the tree-line reproduce by `layering' which means that they do not produce seeds but instead the tree limbs of individual trees produce roots to generate another `tree'. Seeds can only be produced when the summer climate is warm enough. By monitor- ing the reproduction of trees in the tree-line, information can be...

Principal Investigator: Bromley, Robert G.
Licensed Year(s): 1993
Summary: The researcher is interested in determining how many and what kinds of ducks, geese and swans are shot in the spring, as well as how many of the adult females harvested have eggs developing in them. This research has received a Wildlife Research Permit # WL 001432. A licence from the Science Institute is issued in order that the researcher can receive support from the Inuvik Research Centre....

Summary: This ongoing study will involve observing glaucous gulls as they prey on nests of black brant and lesser snow geese. I will attempt to determine why the gulls seem to be more successful when attacking the nests of brant than those of snow geese. I will examine the feeding behaviour of the gulls and the defense behaviour of the geese. I will also examine the nesting success and clutch sizes of b...

Summary: Members of each of the communities will be hired to sample and measure the ringed seals taken in the spring and summer harvests. These monitors will be trained prior to the field season in order to collect data on the size and location of the harvests, as well as measurements on the seals harvested including sexual maturity, health, and condition. Samples of tissue taken will include jaws, lungs...

Principal Investigator: Stabler, Matt
Licensed Year(s): 1993
Summary: The Beluga Harvest Monitoring Program is an on-going program conducted by the Fisheries Joint Management Secretariat that involves the monitoring of the beluga harvest in the Inuvialuit Settlement Region. Data and samples are collected from harvested whales in order to assess contaminant levels as well as population and reproductive parameters....

Principal Investigator: Sandstrom, Stephen J.
Licensed Year(s): 1992
Summary: This project addresses questions pertaining to the energy composition and habitat utilization of female sea-run Dolly Varden char (Salvelinus malma) of the Yukon Slope. The direct consequences of energy partitioning to fucundity (spawning success) and stored energy reserves (overwintering success) have significant effects on population abundance....

Principal Investigator: Krebs, Charles
Licensed Year(s): 1993 1992 1991
Summary: The Researcher and team will continue to study collared lemmings, the most widespread mammaliam herbivore on the Canadian arctic tundra....

Principal Investigator: Stirling, Ian
Licensed Year(s): 1990 1988 1987
Summary: To capture, eartag, and dye-mark polar bears using immobilizing darts and helicopters; collect reproductive organs of seals and polar bears from Inuk hunters throughout the NWT in conjunction with NWT Wildlife Service, tape record underwater vocalizations of marine mammals....

Principal Investigator: Davis, Rolph A.
Licensed Year(s): 1985
Summary: To employ recently developed photogrammetric techniques to determine reproductive parameters of the bowhead whale and the status of the Western Arctic bowhead population; and the sampling of zooplakton to determine the availability of bowhead food in the Canadian Beaufort Sea....
