Summary: This licence has been issued for the scientific research application No. 5982. The objectives of this research project are: 1) To determine the biogeochemical and ecological significance of the discovery that mesic tundra plant growth can be co-limited by nitrogen and phosphorus. 2) To predict the likely impacts of climate change as well as declining caribou and other mammalian herbivory, on tu...

Principal Investigator: Murton, Julian B
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5255. The main objective of the project is to establish the causes of the major changes in sulphur isotopes recorded in fossil bones of mammals at the end of the ice age. To achieve this, the research team will test the working hypothesis that major changes in fossil bone collagen sulphur are linked to changing biogeochemic...

Licensed Year(s): 2018
Summary: Tetra Tech modeled the effects of food chain accumulation of metals and exposure to metals on human health and ecological receptors. Tissue sampling of small rodents (and possibly hares) will be completed to identify trophic transfer of potential soil contaminants in order to verify the model. Snap traps and pitfall traps will be set out by Tetra Tech Staff and two First Nations subcontractors....

Principal Investigator: Amuno, Solomon A
Licensed Year(s): 2017
Summary: The objectives of this research project are to: 1. investigate the effects of chronic arsenic exposure on reproductive parameters, specifically seminal and hormonal parameters including testicular pathology and os penis (baculum) morphology of small mammals (muskrats and squirrels) inhabiting the vicinity of the Yellowknife area, near the Giant mine, and in a reference location approximately 30-8...

Principal Investigator: Amuno, Solomon A
Licensed Year(s): 2016
Summary: The first objective of this preliminary study is to monitor in selected small mammal population, specifically the snowshoe hare population the effects of metal exposure on oxidative stress parameters as well as metalothionenin gene expression and genotoxicity (DNA damage and mutation induction). The second is to monitor effect of metal exposure on bone microstructure alterations, including biomark...

Principal Investigator: Rosindell, Keith
Licensed Year(s): 2002
Summary: A test program has been designed in response to National Energy Board, Department of Fisheries and Oceans, and Resources, Wildlife and Economic Development requests to collect information on seismic airgun acoustics within the Mackenzie River and on asso...

Principal Investigator: Clarkson, Peter
Licensed Year(s): 1993
Summary: The researcher will conduct surveys to determine bear population estimates as well as sex and age distributions for the grizzly bear population in the Brock and Hornaday Rivers area. Licence issued for use of Inuvik Research Centre....

Principal Investigator: Tymstra, Robert
Licensed Year(s): 1993
Summary: This long-term study documents the types of birds found on the major islands in James Bay. Sightings of mammals, amphibians and butterflies will also be recorded. Sampling methods include point counts, line transects and direct counts....

Principal Investigator: Eger, Judith
Licensed Year(s): 1991
Summary: The investigators will study the chromosomal and genetic variation in collared lemmings to assess the effect of isolation of different populations in glacial refugia. They will compare this species with the brown lemming....

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....
