Non-toxic arsenic in mushrooms and plants from Yellowknife
Principal Investigator: Reimer, Kenneth J.
Licensed Year(s): 2012
Summary: The objectives of this research is to: determine total arsenic and arsenic species in edible and non-edible mushrooms from contaminated and uncontaminated locations (mine properties and roadsides/parks); determine total arsenic and arsenic species in plants including Labrador tea, horsetails, buffaloberry, fireweed and berries (if available) from contaminated and uncontaminated locations (mine pro...


Conceptual and Mechanistic Models for the Development and Survival of the Trichostrongylid, Ostertagia gruehneri, in Barrenground Caribou, With Respect to Northern Climate Change
Principal Investigator: Hoar, Bryanne M
Licensed Year(s): 2009 2008 2007
Summary: The objective of this study in 2009 is to determine if parasites (Ostertagia gruehneri) can survive on the tundra over winter. This is the third year of a three year study. This work is to study the parasite Ostertagia gruehneri. This is the most common stomach worm in barrenground caribou. Adult worms live in the stomach of caribou and eggs are shed in the feces of the caribou. Once in the env...


UV-B Impacts On The Microbial Food Web In High Arctic Freshwater Ecosystems
Principal Investigator: Vincent, W.F.
Licensed Year(s): 1994
Summary: There is increasing evidence that levels of solar UV-B radiation have begun to rise in the high Arctic. Little is known about microbial life-forms in the ecosystems of Arctic lakes and rivers and their UV-B resistance. A sampling hole will be drilled in the lake ice. These samples of zooplankton will be studied by a microscope. Samples of water and periphytic communites will also be taken. Underw...


Remote Sensing of Ocean Color in the High Arctic.
Principal Investigator: Cota, Glenn
Licensed Year(s): 1994 1993 1992 1991
Summary: Light leaving the ocean's surface can be detected remotely by satellite. With the proper conversion factors satellites can tell us the amount & growth of plant material in the oceans. Microscopic plants comprise the base of the marine food chain, serving as food for all animals. Because of their dark coloration plants absorb light & produce heat. We are studying what colors & how much light is abs...
