Summary: This licence has been issued for the scientific research application No.5331. The objectives of this project are to monitor beaver occurrence changes; to assess past beaver occupancy patterns using shrub ring analysis; and to understand how permanent and transient beaver populations impact their environment. The research team will conduct canoe and boat-based visual surveys to map beaver dis...

Summary: The objectives of this research project are: 1) to re-assess the anadromous component of the known Vittrekwa River Dolly Varden char population; 2) to investigate & assess other potential suitable Dolly Varden habitat; and 3) to confirm the presence of Dolly Varden char in the Stony Creek watershed. For the Vittrekwa River the research team plans to construct a fixed weir which will trap se...

Summary: Specific activities for this field season include the following: (1) Resolution of the sources and fates of dissolved organic carbon (DOC) in aquatic food webs of the Mackenzie Delta (year 3 of PhD thesis project of S. Tank). This information is needed to ultimately understand the relative role of bacterial (fueled by DOC) versus photosynthetic organisms and their importance in ultimately sup...

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2009 2008 2007 2006
Summary: This study is designed to fill science gaps in Environment Canada’s understanding of the structure and functioning of the aquatic environment potentially impacted by various aspects of the Mackenzie Gas Project. While data collected during the Environmental Impact Assessment studies (carried out in conjunction with the proposed construction and operation of the Mackenzie Gas Pipeline) are relative...

Principal Investigator: DeBruyn, Adrian
Licensed Year(s): 1992 1991
Summary: The Researcher will investigate the biology of predaceous insects in terrestrial and freshwater habitats. An inventory of predaceous insects will be conducted through trapping and collecting. Their prey and habits will also be identified....

Principal Investigator: Bailey, Robert C.
Licensed Year(s): 1987
Summary: To sample the organisms living on rock surfaces (benthic invertebrates) in at least 25 streams fo the Mackenzie Delta area. The number of species present and their relative abundance will be estimated and correlated with environmental factors such as the stream size and flow rate. Habitat data will also be collected at each site....

Principal Investigator: Garry, Clarke E.
Licensed Year(s): 1988 1987
Summary: To determine the beetle species that are found in specific biogeographical zones, what species are likely to be found together in specific locations, and what the habitat preferences of the collected species are....

Principal Investigator: McLeod, Curtis
Licensed Year(s): 1980
Summary: To document fish use of shalllow side-channel areas or river margins and to estimate the effect of water level changes on fish habitat. Detailed physical data collection (water levels, velocity and sediment samples) will be undertaken, data will also be collected of fish and small invertebrate use of habitat....

Principal Investigator: de Graff, Dirk
Licensed Year(s): 1979
Summary: To study the over-wintering areas for fish. The study will include sampling of fish, water, plant life, and bottom sediments for population assessments and habitat analysis....

Principal Investigator: Bouckhout, Leo W.
Licensed Year(s): 1978
Summary: As part of an evaluation of the Dempster pipeline route, an aerial survey to determine the geographic extent and numbers of barren-ground caribou wintering in Canada, as well as gross habitat use patterns of caribou....
