Summary: The overall research goal is to determine appropriate methods to restore disturbed sites at Diavik Diamond Mine to productive and sustainable tundra communities following mine closure. There are three main research areas 1) building suitable reclamation substrates for plant establishment and growth, 2) methods of collection and propagation of locally common native plant and lichen species, and 3) ...

Principal Investigator: MacDonald, Glen M
Licensed Year(s): 1993
Summary: As part of an on-going study, this research will involve collecting cores from trees located in the Campbell-Dolomite Uplands (near Campbell Lake). This data will be added to data collected in other locations (past studies) in order to determine how past climate has influenced the growth of trees (as indicated by tree rings within the tree trunk). The research is helpful in trying to understand ...

Summary: As part of a long-term study, we will continue to monitor the field experiments set up at Alexandra Fiord on Ellesmere Island which examine the effects of climate warming on high arctic plants. Small enclosures have been placed on top of the plants in order that the growing conditions such as temperature and moisture can be altered and their influences on the plants examined. This study is part ...

Principal Investigator: Cummins, W. Raymond
Licensed Year(s): 1991 1990 1989
Summary: The Researcher and team will continue to collect information about repiration rates and growth rates in Arctic plants. They will confirm that Arctic plants have low rates of nitrate reductase activity and will determine if relationships exist between rates of respiration, photosynthesis and nitrogen reduction in these plants....

Principal Investigator: Harmsen, R.
Licensed Year(s): 1991 1990
Summary: The Researcher and his team will collect data on plant size, flowering, seed production, survival and for greenhouse germination experiments. Wire enclosures set up in the previous summer will be remapped....

Principal Investigator: Vardy, Catherine
Licensed Year(s): 1990
Summary: The Researcher will survey growth forms at two sites: one highly disturbed (i.e. a roadside) and one undisturbed site ( i.e. a field). The plants will be measured and a shoot removed from approximately 20-100 plants. Seeds will be collected....

Principal Investigator: Cummins, W. Raymond
Licensed Year(s): 1987
Summary: To continue to collecting trips to sample respiration rates, growth rates in arctic plants and to collect plants and seeds....

Principal Investigator: Lewis, Martin
Licensed Year(s): 1987
Summary: To follow the seasonal phenological pattern of nutrient use by the willow, as well as laboratory work involving fertilization experiments....

Principal Investigator: Marvin, LuDean
Licensed Year(s): 1987
Summary: To re-define the classification of the Potentilla nivea L. complex using methods based on modern plant systematics. Some of the techniques and methods to be used will include chromosome counts, pollen and seed viability tests, guard cell measurements, SEM of pollin exine variations, flavonoid chemistry and numerical analyses. Attempts will be made to determine if correlations exist between morph...

Principal Investigator: Lewis, Martin
Licensed Year(s): 1982
Summary: To undertake a study of the rate which some Arctic plants acquire nitrogen. Plants will be collected and analyzed for the amount of nitrogen they contain....
