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: Tremblay-Reinhardt, Nicolas-O.
Licensed Year(s): 1995
Summary: The researchers will collect samples of each plant species (Dryas integrifolia and Erinophorum angustifolium) communities. Non-destructive seeds and leaf samples will be randomly taken from 30 individual plants within sample patches over a one day period in each of the communities. No camp sites or use of vehicles such as ATV's will be utilized....

Principal Investigator: Fehr, Alan
Licensed Year(s): 1995
Summary: The researchers will determine what impact sewage effluent from the Hamlet of Aklavik is having on the water quality and biota downstream. A literature review on the entire Delta will be completed. Interview with people having camps on the Delta and field observations will give an idea of past and present distribution of wood frogs. Water quality samples will be taken and wetland biota describe...

Principal Investigator: Roach, Pat
Licensed Year(s): 1995
Summary: Samples will be initially evaluated on a presence/absence basis and taken further if warranted. The gene probe analytical technique is new and will be employed for all positive samples. Results will be published in a report format which will be submitted to FJMC to FJMC and the HTC. A paper will also be produced for publication in a refereed Journal....

Principal Investigator: Babaluk, John
Licensed Year(s): 1994 1993
Summary: This is a continuing project to survey fish populations of lakes and rivers. In the past population studies have been conducted in the Fish and Raddi lakes, the Sachs River and the Benard River. This year Middle and Kuptan lakes will be surveyed and if there is time Capron and Swan lakes may also be surveyed. The project will also continue studies on genetic and morphological variation in Arcti...

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: Osawa, Akira
Licensed Year(s): 1994
Summary: The researcher will conduct research on jack pine forests along the highways in Wood Buffalo National Park and will also collect stem increment cores from black spruce trees around the latitudinal tree line near Inuvik. This research will consist of remeasurement of permanent plots, foliage distribution and light measurement, establishment of pruning experiment and stem core sampling near Inuvik....

Principal Investigator: Ring, Richard A.
Licensed Year(s): 1993 1992 1990 1987
Summary: As part of a long term study, I will continue to examine the biology of arctic and subarctic insects. Information will be collected on insect distributions as well as insect adaptations to living in environments with extremely cold winters and short summers. Studies on insect communities in the north may be good indicators of global climate change since they are short-lived species with limited a...

Principal Investigator: Wein, Ross
Licensed Year(s): 1993
Summary: The research team will be examining areas of permafrost south of Inuvik and near Hay River in order to assess the rate of loss of permafrost as a result of the warming in climate over the past twenty years. The loss in permafrost may be speeded up following a local fire. The wetlands that replace these areas of permafrost could lead to a greater production of methane (one of the gases that contr...

Principal Investigator: Tallman, Ross F
Licensed Year(s): 1993 1992
Summary: The researchers will work with other scientists to examine the broad whitefish of the Mackenzie River and associated tributaries of the Arctic Red and Peel Rivers. Features such as population size, migration, growth, age of sexual maturity and mortality will be examined. A study of the traditional knowledge of broad whitefish and fishing in the Mackenzie River will also be developed. Training i...
