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 ...

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: Bliss, Lawrence
Licensed Year(s): 1980
Summary: Life history study of the grasses Phippsia algida and Puccinellia vaginata. To compare plant growth forms of these two grasses in low and high Arctic conditions....

Principal Investigator: Lewis, M.C.
Licensed Year(s): 1979
Summary: 1. general vegetation surveys. 2. plant and growth reproduction. 3. diet and food preferences of lemmings. 4. effect of lemming grazing on plant growth and reproduction. 5. mineralnutrition of lichens. 6. atmospheric sampling....

Principal Investigator: Lewis, M.C.
Licensed Year(s): 1978
Summary: Studies to include: (1) general vegetation surveys (2) plant growth and reproduction (3) diet and food preferences of lemmings (4) effect of lemming grazing on plant growth and reproduction (5) determination of mineral nutrition of lichens (6) atmospheric sampling...

Principal Investigator: Lewis, M.C.
Licensed Year(s): 1977
Summary: A general vegetation survey of the island and adjacent mainland to determine growth and reproduction of plants. To conduct a study of the diet and food preferences of lemmings and the effect of their grazing on plant growth and reproduction....

Principal Investigator: Lewis, M.C.
Licensed Year(s): 1976
Summary: Studies of: 1) Plant growth and reproduction as affected by microclimate and grazing, 2) Pollination and seed dispersal of selected species, 3) General vegeational surveying....
