Principal Investigator: Schwert, Donald P.
Licensed Year(s): 1995 1992
Summary: The sample of arctic-alpine ground-beetles will be collected under rocks and by pitfall traps (dixie cups placed in 8 cm diameter drilled holes) in the tundra habitat. All rocks will be replaced exactly and pitfall trap holes refilled with their soil plugs. No chemicals will be used in any of the trapping or collecting. Specimens will be analysed using DNA techniques which include RLPF's and PC...

Principal Investigator: Hebert, Paul D.N.
Licensed Year(s): 1993
Summary: Zooplankton will be collected from lakes and ponds located along a transect between Paulatuk and Shingle Point (Yukon). The specimens that are collected will be identified according to species type and genetic analyses will be performed to determine what species are interbreeding to produce hybrid organisms. Knowledge about zooplankton is important as many organisms (such as fish) depend on thes...

Principal Investigator: Wilson, Chris C.
Licensed Year(s): 1993 1992 1991 1990
Summary: The researcher will be collecting lake trout and/or arctic charr from lakes in the vicinities of Hay River, Inuvik, Paulatuk and Tuktoyaktuk in order to examine the distributions of these species. Samples of liver and muscle tissue will be collected from these fish for genetic analyses: this research will provide information about how different populations are related to each other (i.e., their o...

Principal Investigator: Johnson, Jim
Licensed Year(s): 1992
Summary: Mackenzie River basin broad whitefish represent a mixed-stock population which utilizes different geographical areas for different stages of its life history. The study will examine the role of outer delta lakes and lakes/rivers of the Tuktoyaktuk Peninsula in the life history of the Mackenzie River population....

Principal Investigator: Crease, Teresa
Licensed Year(s): 1992
Summary: The researcher and her team will collect Daphnia pulex (water flea) samples and maintain them in culture to obtain sufficient material for genetic analysis....

Principal Investigator: Reist, James D.
Licensed Year(s): 1991
Summary: This work is a continuation of a 3 year FJMC funded study to determine genetic stock and structure of the broad whitefish population utilized by communities of the Mackenzie River basin....

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: Cosens, Susan
Licensed Year(s): 1990
Summary: The Researcher and team will apply new tag technology and DNA analysis to a study of site tenacity and industrial disturbance of bowhead whales. They will test the feasibility of using sonic tags to track bowheads underwater and will be testing sampling methods for collecting skin from live whales for DNA analysis....

Principal Investigator: Aiken, Susan
Licensed Year(s): 1990
Summary: The Researcher will test some very standard agriculture seeds that have been developed in Alberta to determine whether they will grow in test plots in Iqaluit and Lake Harbour. She will also identify areas across the NWT which may be suitable as long term climatic change monitoring sites....

Principal Investigator: Green, John M.
Licensed Year(s): 1987
Summary: To continue the ongoing study designed to investigate the postglacial dispersal patterns of freshwater and anadromous fishes by determining genetic relationships between fish populations inhabiting the rivers. Tissue samples will be collected and the genetic variations will be determined through analysis for selected proteins....
