Principal Investigator: De Groot, Bill
Licensed Year(s): 1994
Summary: Plant samples will be collected in the field by the researcher after they become dormat for treatment in a lab experiment. Burning treatments will be conducted in the lab where environmental growing conditions and the plant physiological state at the time of the treatment can be better controled. This will be done in order to model the effects of fire on two types of shrubs....

Summary: The researcher will characterize the kinds and numbers of plant species that make up the various plant communities along the Hood River. Five small temperature recording stations will set up along the river, recording hourly temperatures. This will allow the researcher to see the differences in summer temperatures and how it effects the plant communities. The researcher will also try and determin...

Summary: This is the continuation of a multi-year project to determine the long-term (1000's of years) vegetation history. Researchers will collect sediment samples from the bottom of a series of small lakes. Samples of the upermost sediment will be collected with a dredge or short corer. In the lab pollen will be extracted and identified. This data will be entered on a databank to be used to determine th...

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...

Principal Investigator: Henry, Gregory H.R.
Licensed 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 ...

Principal Investigator: Aiken, Susan
Licensed Year(s): 1993 1992 1991
Summary: The researcher will continue her study on NWT grasses. She will collect living plants in order to conduct chemical analyses on the plant tissue. These tests will help to identify different species of grasses (especially those that look very similar) and also help to determine where these species originated from. In addition, the researcher has small experiments on grass being conducted by staff...

Principal Investigator: Bliss, Lawrence
Licensed 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....

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....

Principal Investigator: Henry, Gregory H.R.
Licensed Year(s): 1994 1993 1992
Summary: As part of a long-term study, we will continue to monitor the field experiments set up at Alexandra Fiord on Ellesmere Island which examine the effects of climate warming on high arctic plants. Small enclosures have been placed on top of the plants in order that the growing conditions such as temperature and moisture can be altered and their influences on the plants examined. This study is part ...

Principal Investigator: Smith, David L.
Licensed Year(s): 1993
Summary: This study will address the impact that muskoxen are having on sedge meadows (the habitat that is important for their survival in the Thomsen River valley). In this study, I will examine the response of sedge meadow plants to the effects of grazing by muskoxen. I will monitoring the growth and chemical makeup of plants in 3 situations: (1) unprotected plots subject to muskoxen grazing; (2) artif...
