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: Montgomerie, Robert D.
Licensed Year(s): 1992
Summary: The researcher and his team will determine the extent of local and geographic variation in Lapland longspur songs. As well, they will look at the variety of strategies used by female birds to ensure their reproductive success in a cold environment. They will also examine the ability of eggs to withstand cold temperatures and the methods used by females in raising their offspring....

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: Orr, Jack
Licensed Year(s): 1993 1992 1991
Summary: The research is a cooperative management data collection program organized by the HTAs and DFO. Under contract the HTAs in Igloolik and Hall Beach will organize, distribute and collect sample kits used by local hunters. These sample kits will provide information on the size and age of killed walrus, along with their genetic code and reproductive status....

Principal Investigator: Fahselt, D.
Licensed Year(s): 1992 1991 1990
Summary: Samples of all colonizing lichen species will be collected, identified and examined for apothecal and spore production. Photographic records will be taken. Samples of umbilicate lichens will be collected and later analyzed for genetic variability. Temperature gradients will be established and distances from first establishment to ice mass will be measured....
