Biophysical Study-Inuvialuit Settlement Region
Principal Investigator: Komers, Petr
Licenced Year(s): 2001
Summary: Eleven plant species of national significance are found in the Mackenzie Delta. Following a preliminary classification using satellite images, the presence or absence of these species within sample areas will be determined during field surveys. After field data are collected, a more refined landscape classification model will be produced. To refine and test this model, 30 sites per vegetation com...


Constraints To Ecosystem Development in High Arctic Polar Deserts
Principal Investigator: Bliss, Lawrence
Licenced Year(s): 1994
Summary: We seek to better understand how ecosystems develop in the high arctic following retreat of ice caps. This includes studies of soil development and the influence that rocks play in this as well as studying the development of block crusts of organisms that form on the soil surface. We will also try to understand the role these crusts play in fixing nitrogen and influencing the development of flower...


Changes in plant communities from subarctic forest to tundra
Principal Investigator: Henry, Gregory H.R.
Licenced Year(s): 1995 1994 1993 1991
Summary: This study continues from the research conducted in 1991 where we examined the plant community and assessed plant distribution as the subarctic forest changes to tundra. We are interested in how the smaller plant species are influenced by changes in the number of trees that are nearby as well as changes in climate. Permanent plots will be established in order to monitor any changes in the plant ...


The role of soil algae in high arctic ecosystem development
Principal Investigator: Bliss, Lawrence
Licenced Year(s): 1993 1992 1991 1989 1988
Summary: The researcher will continue his long term work on plants in a high arctic polar desert. More specifically, this study will examine the small organisms that live in the soil and how these organisms interact with and provide benefits to plants....


Ethnobotany of North Baffin Island Inuit: Native Knowledge of Plant Resources in Kangaqlugaapik, NWT.
Principal Investigator: Borre, Kristen
Licenced Year(s): 1992
Summary: The researchers will collect samples of plants Inuit indicate are important to their lives, including nutritional, economic, ecological, social, cultural and religious importance. The uses and meaning of the plants and the land on which they grow will be discussed with Inuit and recorded. The way in which Inuit think about plants and how they use them will be analyzed....


Effects of Predicted Climate Change on High Arctic Plants
Principal Investigator: Henry, Gregory H.R.
Licenced Year(s): 1994 1993 1992
Summary: The researcher and his team will use simple experiments in the field to simulate the warming climate, and then measure how the timing of the life cycle events (phenology) and growth of each species is affected....


Evolution of High Latitude Floras
Principal Investigator: Basinger, James F.
Licenced Year(s): 1994 1993 1992 1991 1990 1989 1988 1987
Summary: The researcher and his team will continue the study of the evolution of plants and climate in the very high latitudes, and will continue to assemble an extensive collection of fossil plants from northern Canada....


Grasses of the NWT
Principal Investigator: Aiken, Susan
Licenced Year(s): 1993 1992 1991
Summary: The researcher and her team will collect living plants from a 1 km area collection site. Populations will be collected and taken to Ottawa for analysis. This will be a continuation of field work that took place in 1991....


Northwest Passage Expedition
Principal Investigator: Viren, Tom
Licenced Year(s): 1991
Summary: Mr. Lonnie Dupre, Mr. Malcolm Vance and Mr. Jon Nierenburg will collect snow and plant material samples on behalf of Mr. Derik Muir, Department of Fisheries and Oceans, Canada and Mr. Dan Jaffe, Geophysical Institute, University of Alaska, Fairbanks....


Hierachy of Stress Tolerance for Flowering Plants in Extreme Polar Desert and Secondary Metobolites in Prostrate Willows in Sverdrup Pass, Ellesmere Island
Principal Investigator: Svoboda, Josef
Licenced Year(s): 1994 1993 1992 1991 1988 1987
Summary: The Researcher will continue an ongoing program in Sverdrup Pass: Ecology of polar oases. The study will assist in understanding the origin, development, maintenance and future of these isolated ecosystems in the midst of a polar desert....
