Principal Investigator:Tate, Douglas Licenced Year(s):
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...
Principal Investigator:Siciliano, Steven D Licenced Year(s):
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...
Principal Investigator:Aiken, Susan Licenced Year(s):
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...
Principal Investigator:Gillespie, Lynn J. Licenced Year(s):2003
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...
Principal Investigator:Tremblay-Reinhardt, Nicolas-O. Licenced Year(s):
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....
Principal Investigator:Cummins, W. Raymond Licenced Year(s):19911990
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...
Principal Investigator:Basinger, James F. Licenced Year(s):199419931992199119901989
Dr. Basinger is continuing to investigate and collect the fossils that remain of the tropical forest that once grew in the High Arctic....
Principal Investigator:Daborn, G. Licenced Year(s):
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....
