Summary: To determine how spring and summer temperatures affect the abundance of the amphipod Gammarus lacustris throughout the summer. Over the 2 years of the experiment, the research team plans to use amphipods from 4 different sources over several latitudes (Montana-USA, St. Denis-SK, Yellowknife-NT, Inuvik, NT). Using this variety of geographic sources will allow us to assess if different populations...

Licensed Year(s): 1996 1995
Summary: As part of overall reclamation goals of BHP, the 1996 season will focus on three components. Vegetation response will be assessed in August using the point-frame method. Within the legume, indigenous seed and shrub cutting plots, plant density will be recorded. Soil samples in replicates of three will be collected from each treatment to analyze physical and chemical characteristics. Secondly, ...

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: Nicholson, Barbara
Licensed Year(s): 1992
Summary: The Researcher will map the present distribution of boreal and subarctic wetlands in the Mackenzie River Basin. Wetland vegetation and water chemistry will be described for areas immediately surrounding permanent weather stations. The ecological relationships between climate, wetland water chemistry and wetland species distribution will be analyzed. A predictive indicator model will be built to pr...

Principal Investigator: Trauger, David
Licensed Year(s): 1978
Summary: To revisit areas studied in 1966-70 to check a wetland classfication system and to determine if there are any changes in the species composition and abundance of various migratory game birds....
