Reclamation of Disturbed Sites Research at Diavik Diamond Mine, NWT
Principal Investigator: Naeth, M. Anne
Licensed Year(s): 2017 2016 2015 2014 2009 2008 2005
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) ...

Post-glacial treeline change in the Campbell-Dolomite Uplands of the Inuvik area
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 ...

Effects of predicted climate change on high arctic plants
Principal Investigator: Henry, Gregory H.R.
Licensed Year(s): 1994 1993 1992
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 ...

To Study Control of Metabolic Rates in Arctic Plants
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....

Effect of Muskox Grazing on "Oxytropis glutinosa"
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....

Apical Dominance and Growth Form in Herbaceous Sub-Arctic Plants
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....

Licence #7116
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....

The Mineral Nutritions of the Arctic Willow, Salix Arctica.
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....

A biosystematic treatment of the Potentiall nivea L. complex in North America.
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...

Licence #2774
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....
