Overbank sediment patterns on the Mackenzie Delta
chercheur principal: Pearce, Cheryl M.
Année(s) de permis: 1993 1992 1991 1990
Résumé: The researcher will continue her long-term study on the physical features of the Mackenzie Delta. Hydrocarbon development, water volume and course changes, and climate change could have major effects on the water and sedimentation patterns of the delta. This study will increase knowledge of sedimentation patterns, shoreline erosion and their relationships with vegetation....

Spatial and Temporal Variation of Vegetation on Raised Beaches, Devon Island
chercheur principal: Pearce, Cheryl M.
Année(s) de permis: 1988 1987
Résumé: Dr. Pearce and her associate are returning to Truelove Lowland to evaluate an idea that plant associations growing on raised beaches of different ages are a result of the type of soil and water conditions they are growing on rather than the amount of time that they have had to live there....

The relationships between modern pollen sedimentation and present vegetation distribution on Truelove Lowland, Devon Island.
chercheur principal: Pearce, Cheryl M.
Année(s) de permis: 1987
Résumé: To 1) collect and analyze present-day pollen sedimentation from major plant communities on several high arctic site types, 2) to correlate this production with actual plant cover, and 3) to compare the modern pollen rain to historical pollen deposits analyzed in the Department of Geography, University of Western Ontario (R. King) and during the I.B.P. Project (Jankovska and Bliss)....

Vegetation Dynamics on Shorelines of Mackenzie Delta, N.W.T.
chercheur principal: Pearce, Cheryl M.
Année(s) de permis: 1987
Résumé: To analyze the environmental processes that control plant distribution and succession on shorelines of the Mackenzie Delta. Specific objectives of the research are to examine (1) the colonization and establishment on exposed mudflats and other newly-available sites, (2) the responses of the shoreline plants to fluctuations in the biophysical environment, and (3) the chemical and physical properti...
