Examining the impacts of climate change on aquatic and terrestrial ecosystems of the Mackenzie region, NWT
Principal Investigator: Pisaric, Michael FJ
Licensed Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The objectives of this research are to examine the impacts of climate and environmental change on freshwater ecosystems in the Inuvik region across a variety of spatial and temporal scales. Specifically, the team is examining the impacts of permafrost degradation and subsequent thaw slumping on freshwater ecosystems and the impact of climate change on tree growth in the Mackenzie Delta. Lake s...


Tundra Northwest 1999
Principal Investigator: Karlqvist, Anders
Licensed Year(s): 1999
Summary: The overall goal of the expedition Tundra Northwest 1999 is to study geographic variation of terrestrial and freshwater ecosystems of the tundra. By using the CCG icebreaker Louis St. Laurent for transport and as a scientific platform the the expedition route will include a longitudinal gradient from Baffin Island to the northern coast of Alaska and a latitudinal gradient through the Canadian Arc...


UV-B Impacts On The Microbial Food Web In High Arctic Freshwater Ecosystems
Principal Investigator: Vincent, W.F.
Licensed Year(s): 1994
Summary: There is increasing evidence that levels of solar UV-B radiation have begun to rise in the high Arctic. Little is known about microbial life-forms in the ecosystems of Arctic lakes and rivers and their UV-B resistance. A sampling hole will be drilled in the lake ice. These samples of zooplankton will be studied by a microscope. Samples of water and periphytic communites will also be taken. Underw...


Ecology and population genetics of freshwater invertebrates of the Arctic.
Principal Investigator: Boileau, Marc G.
Licensed Year(s): 1988 1987 1986
Summary: To investigate the ecology and population genetics of crustacean zooplankton. To study the genetic diversity of the major species of copepods and their dispersal since deglaciation. To clarify the taxonomy and improve distribution records....


Freshwater Red Algae in North America
Principal Investigator: Sheath, Robert
Licensed Year(s): 1987
Summary: To clarify freshwater red algae classification by determining key stable and non-overlapping structural characteristics needed to clearly separate species. Collecting trips will be made to all major drainage basins of the Atlantic, Pacific and Arctic. Preserved samples will be analyzed by computerized microscopy and live samples will be cultured under varied growth conditions to induce potential ...


Licence #5127
Principal Investigator: Boileau, Marc G.
Licensed Year(s): 1985
Summary: To continue investigations on the ecology and population genetics of crustacean zooplankton: to focus on the genetic diversity of the four major species of copepods inhabiting the freshwater ponds in the Arctic and the distribution and dispersal of these species since glaciation....
