Biological Studies of Waters Along the Proposed Mackenzie Gas Project Pipeline Route - Gwich'in Settlement Area
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2009 2008 2007 2006
Summary: This licence is being issued for the scientific research application no. 983. The objective of this study 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 ...

Forestry Research in the Gwich'in Settlement Area
Principal Investigator: Walker-Larsen, Jennifer
Licensed Year(s): 2003 2002 2001 2000
Summary: Forest Fire Effects on Vegetation and Wildlife Habitat use: Research sites will be accessed by helicopter. Sites are located in burns of different ages. In the summer, small teams will complete vegetation plots, assess species composition and percent cover, and assess wildlife abundance. In the winter, helicopter track surveys will be completed. Forest Monitoring (ARNEWS and SI/MAB plots): The...

Distribution, Systematics and Genetic Structure of Arctic Zooplankton.
Principal Investigator: Hebert, Paul D.N.
Licensed Year(s): 1994 1992
Summary: The research involves the use of helicopters with floats to sample the animal life present in lakes on the Melville Peninsula and northwestern Baffin Island. Most of our work will concentrate on the capture of zooplankton, small animals which foram an important part of the diet of young fish. After the collections are made, the samples are taken back to the Igloolik labratory, where they are sor...

Distribution, systematics and genetic structure of western arctic zooplankton species
Principal Investigator: Hebert, Paul D.N.
Licensed Year(s): 1993
Summary: Zooplankton will be collected from lakes and ponds located along a transect between Paulatuk and Shingle Point (Yukon). The specimens that are collected will be identified according to species type and genetic analyses will be performed to determine what species are interbreeding to produce hybrid organisms. Knowledge about zooplankton is important as many organisms (such as fish) depend on thes...

Changes in plant communities from subarctic forest to tundra
Principal Investigator: Henry, Gregory H.R.
Licensed Year(s): 1995 1994 1993 1991
Summary: This study continues from the research conducted in 1991 where we examined the plant community and assessed plant distribution as the subarctic forest changes to tundra. We are interested in how the smaller plant species are influenced by changes in the number of trees that are nearby as well as changes in climate. Permanent plots will be established in order to monitor any changes in the plant ...

Nesting-bird habitat relationships on the Yukon Coastal Plain: A program to establish initial relationships and populations (April 1992 to March 1994)
Principal Investigator: Hawkings, James S.
Licensed Year(s): 1993
Summary: The populations of nesting birds will be determined in a selected number of plots that represent the various tundra habitats on the Yukon Coastal Plain. The selected plots will be surveyed on foot during the spring (June) to identify the most important habitats for bird species nesting on the coastal plain. This project has been approved by the North Slope Wildlife Management Advisory Committee....

Initial Aquatic Inventory, Izok Lake Mine Project
Principal Investigator: Ash, Gary R.
Licensed Year(s): 1994 1993 1992
Summary: The researchers will obtain baseline water quality data for the study waterbodies, discharge information for the major streams in the study area, baseline information on fish species composition and relative abundance in the study area, and information of background levels of metals in fish tissue from selected waterbodies in the area....

Mitochondrial DNA Diversity in High-Arctic Populations of Daphnia pulex (water fleas)
Principal Investigator: Crease, Teresa
Licensed Year(s): 1992
Summary: The researcher and her team will collect Daphnia pulex (water flea) samples and maintain them in culture to obtain sufficient material for genetic analysis....

Principal Investigator: Couture, Richard
Licensed Year(s): 1991
Summary: The Researchers will conduct a sampling program to describe the current state of the fisheries resources in the Rio Fido - Frayed Knots River drainage....

An Examination of Disturbance to Plant Communities on Truelove Lowland, Devon Island, N.W.T.
Principal Investigator: Hewitt, Nina
Licensed Year(s): 1991
Summary: The Researcher will carry out field work in association with Dr. Cheryl M. Pearce. The research will measure the nature and extent of human disturbance within the dominant plant communities on Truelove Lowland and attempt to correlate the disturbance with species composition, surficial materials, and the type of disturbance....
