Biological Studies of Waters Along the Proposed Mackenzie Gas Project Pipeline Route - Inuvialuit Settlement Region
chercheur principal: Evans, Marlene S.
Année(s) de permis: 2009 2008 2007 2006
Résumé: This license has been issued for the scientific research application #837. This study is designed to examine lakes possibly affected by the proposed Mackenzie Gas Project pipeline, and lakes that can serve as future control/reference sites. The researchers will measure the following: nutrients and metals in lake water and sediments, lake water quality (DO, pH, conductivity, etc.), and benthic i...


Biological Studies of Waters Along the Proposed Mackenzie Gas Project Pipeline Route - Gwich'in Settlement Region
chercheur principal: Evans, Marlene S.
Année(s) de permis: 2009 2008 2007 2006
Résumé: This licence is issued for the scientific research application # 835. This research will examine lakes possibly affected by the proposed Mackenzie Gas Project pipeline, and lakes that can serve as future control/reference sites. Measurements of nutrients and metals in lake water and sediments, lake water quality (DO, pH, conductivity, etc.), and benthic invertebrate and plankton abundance/spec...


Dust Distribution and Monitoring using Lichens as Bioindicators
chercheur principal: Wytrychowski, Scott I
Année(s) de permis: 2013 2010 2005
Résumé: Air quality is an issue at mine sites, and diamond mining can contribute large quantities of dust to the air. This dust may contain elevated levels of heavy metals. Vehicle and generator exhausts also contribute to air pollution and greenhouse gases. To acheive the goal of sustainable development, Diavik policy focuses on the need to identify potential risks and set targets for pollution preventio...


Butterfly Inventory in the NWT
chercheur principal: Layberry, Ross
Année(s) de permis: 2005
Résumé: Butterflies are easily studied and can provide valuable information of changes occuring in northern ecosystems - including climate changes, and habitat changes. Many areas of the NWT have few studies on insects; therefore, this inventory work can inprove the baseline information of these species. The main investigator will travel with other NWT biologists to remote study sites and near comm...


Analaysis of Bathurst Caribou Herd Dynamics Using a Proxy Indicator
chercheur principal: Zalatan, Rececca
Année(s) de permis: 2004 2003
Résumé: Caribou populations fluctuate over long time spans. However, long-term records of population cycles are scarce. The population dynamics of the Bathurst and Beverly caribou herd across the Northwest Territories will be reconstructed using two proxy indic...


Fisheries Studies For 2002 Aquatic Effects Monitoring Program
chercheur principal: Landry, Francois
Année(s) de permis: 2002
Résumé: The field work is intended to provide baseline fisheries data for four lakes (Horseshoe, Toss, Fay and Logan) and to obtain post-baseline fisheries data on eight lakes (Vulture, Kodiak, Nema, Cujo, Nanuq, Counts, and Slipper) within the Ekati claimblock...


Reproductive Ecology of Tundra Swans in the Mackenzie Delta Region
chercheur principal: Swystun, Heather
Année(s) de permis: 2002 2001
Résumé: Two individuals from each of the communities of Inuvik, Aklavik, Tsiigehtchic, Fort McPherson, and Tuktoyaktuk will be interviewed about their local knowledge of tundra swan biology. Information collected will educate the researcher about local tundra swan ecology and may help generate questions that are important to communities. Interview methods will follow those used by the Arctic Borderlands E...


Measuring Genetic Diversity in Small False Asphodel, Tofieldia pusilla (Liliaceae), in Glacial Refugia, Disjunct Populations on Lake Superior and Across its Broad Arctic Range : A Tool for Prioritizing Sites for Conservation
chercheur principal: Line, Jennifer
Année(s) de permis: 2000
Résumé: This research will contribute to an increased understanding of ecological integrity in Nahanni National Park, provide information on the importance of glacial refugia as banks of genetic diversity and highlight the value of genetic diversity as an indicator of ecological integrity. The researcher will be transported to sampling sites within the park by Parks Canada staff (plane, helicopter). At...


Studies on the past, present and future ecological impact on Canadian northern boreal forest and arctic ecosystems due to mining activities, shown at the Great Slave Lake area, Northwest Territories, Canada
chercheur principal: Steinecke, Karin
Année(s) de permis: 1998 1997
Résumé: The project will focus on understanding, analyzing and evaluating the reactions of the northern boreal forest ecosystems in the Great Slave Lake region due to man made stress of mining, settlement and connecting activities. The project will try to develop some general conclusions, statements and model systems. The research team (2 persons) will come from Europe to Yellowknife by plane. The base wi...


Hybridization and genetic variation in arctic grasses: molecular, morphological and ecological evidence
chercheur principal: Gillespie, Lynn J.
Année(s) de permis: 1997 1995 1994
Résumé: The researcher will collect living plants (Arctic grasses), 6 - 10 species from each collection site. In addition, several plants of each species will be pressed and dried as voucher specimens to be used to check the identification. Photographs of the plants and their habitats will be made. In Ottawa, variations in DNA among different populations and species will be analyzed to study species re...
