Status and Occurrence of Nahanni Aster (Symphyotrichum nahanniense) in Nahanni National Park Reserve and Vicinity
Principal Investigator: Tate, Douglas
Licenced Year(s): 2003
Summary: The Nahanni aster is a small plant that is known to be found at only three hotspring sites within Nahanni National Park Reserve. This study proposes to visit the three known sites (by helicopter) to survey the number of asters present and collect some s...


Trace Contaminant Transformation and Fate in Northern Ecosystems
Principal Investigator: Siciliano, Steven D
Licenced Year(s): 2003
Summary: This study will: (1) assess sulfate-reducing bacterial diversity and mercury transformations; and (2) analyze the toxicity of contaminants deposited on vegetation and soil to wildlife that may digest it. Little is known about transformations of mercury...


Flora of the Canadian Arctic Archipelago
Principal Investigator: Aiken, Susan
Licenced Year(s): 2001 1999
Summary: The research team will be based in Tuktoyaktuk, and travel by scheduled flight from Inuvik. No field camps will be used, and all transport in the field will be on foot. Data will be collected primarily through photographic documentation of both the plants of interest, and the typical environments in which these plants are found. A single voucher specimen of each plant photographed will be mainta...


Canadian Arctic Plants: Systematics and Evolution
Principal Investigator: Gillespie, Lynn J.
Licenced Year(s): 2003 2000
Summary: The research team will make short visits to many sites in order to observe how plants vary morphologically and genetically from site to site across the arctic region. They will visit Mould Bay on Prince Patrick Island, Warrington Bay and McCormick Inlet on Melville Island. At each site the researchers will make observations on the morphology, ecology, reproductive biology, and distribution of eac...


Molecular population genetics and phytogeography of arctic flora.
Principal Investigator: Tremblay-Reinhardt, Nicolas-O.
Licenced Year(s): 1995
Summary: The researchers will collect samples of each plant species (Dryas integrifolia and Erinophorum angustifolium) communities. Non-destructive seeds and leaf samples will be randomly taken from 30 individual plants within sample patches over a one day period in each of the communities. No camp sites or use of vehicles such as ATV's will be utilized....


To Study the Role of Alternative Pathway Respiration in Arctic Plants
Principal Investigator: Cummins, W. Raymond
Licenced Year(s): 1991 1990 1989
Summary: Professor Cummins and his team will estimate potential productivity of plants in northern ecosystems and will investigate further the exceptionally high rate of respiration and alternative pathway respiration which they have discovered in arctic plants. They will use nitrate and ammonium electrodes to survey the levels of available nitrogen in wet and dry meadows on Devon...


Evolution of high latitude floras
Principal Investigator: Basinger, James F.
Licenced Year(s): 1994 1993 1992 1991 1990 1989 1988 1987
Summary: Dr. Basinger is continuing to investigate and collect the fossils that remain of the tropical forest that once grew in the High Arctic....


Flora of central coastal Keewatin, NWT
Principal Investigator: Cameron, Duncan
Licenced Year(s): 1988
Summary: to characterize flora in area of Eskimo Point...

Licenced Year(s): 1977
Summary: Continuation of baseline data collection of the distribution and physiological phenomena of Arctic flora and fauna....


Licence #1886
Principal Investigator: Daborn, G.
Licenced Year(s): 1975
Summary: The collection of base-line data on the distribution and physiological phenomena af Arctic flora and fauna. Two specific on-going studies pertain to levels of pesticide residues in livers of mammals, birds and fish....
