Biochemical and metabolomic impact of trace metals (As, Sb, Cd, Ag, La, Ce) in various fish species and amphipods collected from the metal-impacted Yellowknife area
Principal Investigator: Rosabal, Maikel
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5278. The main goal is to generate a specific knowledge about the implications of metals bioaccumulated observed in the population of three species of fish (e.g., northern pike, lake whitefish, yellow perch) and invertebrates (H. azteca) inhabiting ecosystems located in this mining region. The specific objectives are: 1) to...


Remote Sensing of Arctic Vegetation Biochemistry
Principal Investigator: Kennedy, Blair E
Licensed Year(s): 2014 2013
Summary: The objectives of the research are: (1) measure the spectral properties (i.e. how light is absorbed and reflected) and biochemical constituents (e.g. chlorophyll, water, nitrogen, carbon) of arctic vegetation at the ground-level in various vegetation communities across the Western Arctic (e.g. low-arctic to high-arctic); (2) investigate the potential of using satellite based multi-angular imaging ...


Biogeochemistry of Lakes in the Mackenzie Delta
Principal Investigator: Lesack, Lance
Licensed Year(s): 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: The long-term goal of this research is to develop a model of the interacting biogeochemical and hydrologic processes that control the nutrient balance and primary productivity of lakes in the Mackenzie Delta region, and ultimately, a more general model for lakes associated with the flood plains and deltas of major world rivers. Work based at the Inuvik Research Centre will consist of field and lab...


Muskoxen-sedge meadow interactions
Principal Investigator: Smith, David L.
Licensed Year(s): 1993
Summary: This study will address the impact that muskoxen are having on sedge meadows (the habitat that is important for their survival in the Thomsen River valley). In this study, I will examine the response of sedge meadow plants to the effects of grazing by muskoxen. I will monitoring the growth and chemical makeup of plants in 3 situations: (1) unprotected plots subject to muskoxen grazing; (2) artif...


Isozyme Variability of Lichens in Relation to Latitude
Principal Investigator: Fahselt, D.
Licensed Year(s): 1992 1991 1990
Summary: The Researcher will compare the levels of enzyme variation from populations of umbilicate species from the Arctic as well as from the southern limit of their ranges in southeastern USA. The objective will be to ascertain whether there is any correlation between the level of variability in enzyme patterns and latitude....


Hierachy of Stress Tolerance for Flowering Plants in Extreme Polar Desert and Secondary Metobolites in Prostrate Willows in Sverdrup Pass, Ellesmere Island
Principal Investigator: Svoboda, Josef
Licensed Year(s): 1994 1993 1992 1991 1988 1987
Summary: The Researcher will continue an ongoing program in Sverdrup Pass: Ecology of polar oases. The study will assist in understanding the origin, development, maintenance and future of these isolated ecosystems in the midst of a polar desert....


Nutrition and Distribution of Arctic Marine Zooplankton in Relation to the Physical Environment
Principal Investigator: Gustavson, Kent
Licensed Year(s): 1991 1990
Summary: The Researcher will continue to study the distribution of phytoplankton and zooplankton in the Barrow Strait area. The herbivourous plankton species which feed on the marine algae and phytoplankton is the first step in the arctic food chain. It is the herbivorous plankton which is the source of food for other animals which ultimately provides food for all other higher arctic animals....


Licence #2197
Principal Investigator: Barry, T.W.
Licensed Year(s): 1977
Summary: To study the hormones and biochemistry of the red wattles on male, non-nesting willow ptarmigan....
