The Broad Whitefish Traditional Ecological Knowledge Study.
Principal Investigator: Freeman, Milton M.R.
Licenced Year(s): 1994 1993 1992
Summary: The research team will carry out interviews with the Inuvialuit that are knowledgable about 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 the local environmental changes on whitefish....


Shallow water benthic fish communities of Resolute Bay
Principal Investigator: Green, John M.
Licenced Year(s): 1993 1990 1988
Summary: As part of a long-term study, I will continue to make underwater observations of the benthic fishes found in the shallow waters of Resolute Bay. Some fish will be collected for further laboratory studies in order to examine their food habits, growth rates and population growth rates. The species Gymnelus viridis will be studied in greater detail....


International Conservation Strategy for the Endangered Bowhead Whale of Baffin Bay
Principal Investigator: Finley, Kerry J.
Licenced Year(s): 1994 1993 1992
Summary: The researcher and his team will determine numbers, distribution and local movements of bowheads and provide detailed data on the activity budgets and surface-dive parameters of bowheads to correlate with patterns of habitat use. As well, they will document the feeding patterns of bowheads, and are proposing to use satellite telemetry to study the larger scale movements of bowheads in Baffin Bay....


Environmental Physiology of Marine Invertebrates
Principal Investigator: Graham, Mark
Licenced Year(s): 1992
Summary: The researcher and his team will use several species of planktonic and benthic invertebrates from Lancaster Sound region to evaluate the metabolic cost of making a living in the Arctic. Oxygen consumption techniques will be used as a metabolic indicy. Trophic status of specimens will be evaluated later by stable isotope analysis....


The Impacts of Muskoxen on a Hygric Sedge Meadow Plant Community, Northern Banks Island, N.W.T.
Principal Investigator: Romo, J.T.
Licenced Year(s): 1992
Summary: The project examines the effects of a high-density muskoxen populations on a sedge meadow plant community. Two fences exist at the study site to exclude muskoxen and thus provide an ungrazed area used for comparison with the grazed area. Plant species abundance, plant height, grazing use of plant species and weight of plants are some of the data that will be compared among grazed and ungrazed are...


Trophic Relationships and Energetics of Arctic Cod in High-Arctic Marine Food Chains
Principal Investigator: Hop, Haakon
Licenced Year(s): 1991 1990 1988
Summary: The Researcher and his assistant will collect Arctic cod. Samples of these will be taken and studied to investigate the feeding ecology of Arctic cod and the energy flow through Arctic cod from zooplankon to marine mammals and sea birds....


Ringed Seal Biology
Principal Investigator: Stewart, Robert E.A.
Licenced Year(s): 1992 1990
Summary: This study involves the weighing, measuring and sampling of ringed seals which are harvested during normal hunting activities around Pangnirtung. Sampling includes the collection of various tissues and organs. This information will be used to estimate how quickly the ringed seal population replaces harvested animals....


Assessment of Reindeer Ranger on the Belcher Islands
Principal Investigator: Henry, Gregory
Licenced Year(s): 1991 1990
Summary: The Researcher and his team will assist the community of Sanikiluaq and the local Hunters and Trappers Association who are concerned about managing the reindeer herd for sustained meat production. In 1978 60 reindeer were introduced on the Belcher Islands and the herd has grown to approximately 530 in 1990....


North Slope Char Summer Ecology Project
Principal Investigator: Sandstrom, Steve
Licenced Year(s): 1990
Summary: 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....


Inter-relationships Between Internally Feeding Insects and Species "Pedicularis" in the High Arctic
Principal Investigator: Meier, Sharon
Licenced Year(s): 1991 1990
Summary: Ms. Meier and her assistant will study plant-insect relationships and factors which play determining roles in the lives of organisms inhabiting the Arctic environment....
