Prescribed Fire and Wildlife Habitat Enhancement
chercheur principal: De Groot, Bill
Année(s) de permis: 1994
Résumé: 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....

Jack Pine Forest Research
chercheur principal: Osawa, Akira
Année(s) de permis: 1994
Résumé: 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....

Biology, ecology and cold tolerance of arctic insects
chercheur principal: Ring, Richard A.
Année(s) de permis: 1993 1992 1990 1987
Résumé: 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...

Fire, carbon budget and climate change
chercheur principal: Wein, Ross
Année(s) de permis: 1993
Résumé: 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...

Monitoring the Mackenzie Delta exploratory fishery
chercheur principal: Dahlke, Lothar
Année(s) de permis: 1993
Résumé: Three crews of two people each will be stationed at the commercial fishing camps to obtain biological and catch effort data from the fisherman. A supervisor will oversee the project in the field and set some experimental nets in the vicinity of the commercial nets at one of the camps. A minimum of 200 whitefish samples will be obtained from the fishermen's catch....

Genetics and postglacial dispersal of lake trout (Salvelinus namaycush) and arctic charr (S. alpinus) in the western arctic
chercheur principal: Wilson, Chris C.
Année(s) de permis: 1993 1992 1991 1990
Résumé: 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...

Grasses of the NWT
chercheur principal: Aiken, Susan
Année(s) de permis: 1993 1992 1991
Résumé: The researcher will continue her study on NWT grasses. She will collect living plants in order to conduct chemical analyses on the plant tissue. These tests will help to identify different species of grasses (especially those that look very similar) and also help to determine where these species originated from. In addition, the researcher has small experiments on grass being conducted by staff...

Regional synchrony of lemming populations in the northern Yukon and Tuktoyaktuk region
chercheur principal: Krebs, Charles
Année(s) de permis: 1993 1992 1991
Résumé: The researchers will examine the cycles in lemming abundance (i.e., increases and decreases in the lemming population) for the western arctic region. Ongoing research suggests that lemmings in the Pearce Point area do not appear to reach very high numbers as has been noted in the eastern arctic and Scandinavia. Licence issued for use of Inuvik Research Centre....

Biogeochemistry of lakes in the Mackenzie Delta
chercheur principal: Lesack, Lance
Année(s) de permis: 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Résumé: This research involves a variety of activities that involve investigating the chemical makeup of ice, streams and lakes. In addition, some work will be conducted on measuring the microscopic and larger organisms (e.g., algae and bugs) present in streams. Most of the field work will be based out of the Inuvik Research Centre with some work conducted in collaboration with Dr. P. Marsh at Trail Val...
