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: Somji, Feisal
Licensed Year(s): 1995
Summary: The researcher will conduct an intensive gillnetting program using multi-mesh gillnet gangs to determine the size and characteristics of fish populaitons in the project area. Both floating and bottom sets will be used, perpendicular and parallel to the shoreline. It is proposed that 40 fish of each species found will be taken from each lake sampled....

Principal Investigator: De Groot, Bill
Licensed Year(s): 1994
Summary: Plant samples will be collected in the field by the researcher after they become dormat for treatment in a lab experiment. Burning treatments will be conducted in the lab where environmental growing conditions and the plant physiological state at the time of the treatment can be better controled. This will be done in order to model the effects of fire on two types of shrubs....

Principal Investigator: Pelletier, Clem
Licensed Year(s): 1994
Summary: In project area streams, fish presence/absence and/or densities will be obtained by electrofishing representative habitat. Benthic invertebrates ans periphyton (stream algae) will be sampled at stream sites to determine seasonal changes in composition, distribution and abundance. Lake fisheries population studies will involve fish trapping. Lake limnology, plankton and benthic invertebrates wil...

Principal Investigator: Ellis, R.A.
Licensed Year(s): 1993
Summary: The mosquito baseline study is aimed at determining which mosquito species breed in and around Yellowknife. While sampling for mosquito larvae, samples of non-target (i.e., other) insect species will also be taken to determine which of these species are natural predators or parasites of mosquitoes, or should be protected for other reasons. The City of Yellowknife will be provided with recommenda...

Principal Investigator: Brotton, Janet
Licensed Year(s): 1993
Summary: The proposed research will investigate the implications of climatic change for fish and wildlife resources in the Mackenzie River Basin. A computer model will be used to predict temperature and precipitation changes associated with an expected doubling of carbon dioxide concentrations. Data points used in the modelling exercise will correspond to selected weather stations in the region. The res...

Principal Investigator: McNaughton, Duane
Licensed Year(s): 1992
Summary: The researcher will drill and complete some 20 observation wells in the vicinity of the Fort Resolution sewage infiltration pit. Sample groundwater and analyze it for sewage derived contaminants and coliform bacteria. A report will be prepared with recommendations based on the findings and submitted to relevant agencies in the N.W.T....

Principal Investigator: Morrison, R.I.G.
Licensed Year(s): 1992 1991 1990
Summary: Work by Dr. Morrison at Alert in the mid 1970's established the Knots and Turnstones breeding on northern Ellesmere Island migrate to wintering grounds on the European seaboard. Most migrate via staging areas in Iceland, though some of the population reaches Ellesmere via Norway. The internationally coordinated research program carried out over the last six years to study the migration, ecophysiol...

Principal Investigator: Sekerak, Aaron D.
Licensed Year(s): 1990
Summary: The Researcher and his assistant will obtain information on fish in the area so that potential impacts of mining in the region can be assessed....

Principal Investigator: Waterway, Marcia J.
Licensed Year(s): 1990
Summary: The Researcher and her team will sample approximately twenty different species of sedges in a range of wetlands between Edmonton and Yellowknife. They will find out the range of conditions in which each species grows best and will determine whether broad tolerance results from inherited variability or from the ability of individuals of each species to tolerate different conditions....
