Changes to plant communities in the Northwest Territories, Canada
Principal Investigator: Singer, Claire L
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5608. Objectives: To investigate the relative invasibility of different regrowth stand types post-fire; and, To complete river surveys of invasive plants downstream of Hay River and Fort Liard. Burns: To assess the invasibility of different regrowth stand types, samples will be taken along transects running perpend...


Potential for large lakes to serve as climate refugia for cold-adapted plants
Principal Investigator: Nielsen, Scott
Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No.5407. The objective of this thesis is to quantify the extent of lake-mediated cooling and its effect on shoreline and inland plant species at varying scales. The principal investigator (PI) will establish a series of transects at large lakes in northern regions of Manitoba, Saskatchewan, Alberta, and the Northwest Terr...


Arctic timberline ecology
Principal Investigator: Broll, Gabriele
Licensed Year(s): 1993
Summary: As part of his trip to Inuvik with the International Tour of Permafrost Affected Soils, the researcher will record information about the ecology (including local climate conditions, soil conditions and plant communities) of the timberline at selected sites visited during the Tour. These sites are located along the Dempster Highway near Inuvik....


Establishment of Lichens in Glacial Recession Zones
Principal Investigator: Fahselt, D.
Licensed Year(s): 1992 1991 1990
Summary: Samples of all colonizing lichen species will be collected, identified and examined for apothecal and spore production. Photographic records will be taken. Samples of umbilicate lichens will be collected and later analyzed for genetic variability. Temperature gradients will be established and distances from first establishment to ice mass will be measured....


An Evaluation of SPOT Data to Map Ground Cover in the Canadian High Arctic
Principal Investigator: Jetty, Tammy
Licensed Year(s): 1991
Summary: The Researcher will carry out fieldwork in association with Dr. Cheryl M. Pearce. The study will investigate if the the response of arctic surfaces to climate changes can be detected, monitored and mapped using space imagery....


An Examination of Disturbance to Plant Communities on Truelove Lowland, Devon Island, N.W.T.
Principal Investigator: Hewitt, Nina
Licensed Year(s): 1991
Summary: The Researcher will carry out field work in association with Dr. Cheryl M. Pearce. The research will measure the nature and extent of human disturbance within the dominant plant communities on Truelove Lowland and attempt to correlate the disturbance with species composition, surficial materials, and the type of disturbance....


Plant communities of Shoran Lake and Sachs Harbour, Banks Island, NWT
Principal Investigator: Thannheiser, Dietbert
Licensed Year(s): 1988
Summary: Dr. Thannheiser is from West Germany. He will be collecting plants and describing the types and quantities of plants growing in different habitats....


The role of soil algae in the development of High Arctic ecosystems
Principal Investigator: Bliss, Lawrence
Licensed Year(s): 1993 1992 1991 1989 1988
Summary: Dr. Bliss and his research team are returning to continue their investigation of how soil develops from bare rock along the ocean edge. Seaweed washes up on shore and rots. Small plants grow on the rotting seaweed and help to form soil. As the soil gets thicker, larger plants such as those eaten by muskox and geese begin to grow. This is how the rich coastal lowlands have been formed which are...


Spatial and Temporal Variation of Vegetation on Raised Beaches, Devon Island
Principal Investigator: Pearce, Cheryl M.
Licensed Year(s): 1988 1987
Summary: Dr. Pearce and her associate are returning to Truelove Lowland to evaluate an idea that plant associations growing on raised beaches of different ages are a result of the type of soil and water conditions they are growing on rather than the amount of time that they have had to live there....


Interpretation of southern Baffin Island tundra vegetation from Landsat images
Principal Investigator: Skelly, William Chris
Licensed Year(s): 1988
Summary: Mr. Skelly will be looking at plants and their ability to reflect light to determine how they would look on a photograph taken from a Landsat satellite....
