Summary:
The Permanent Monitoring Plots will provide experimental data on forest growth and progression, cumulative impact monitoring, and will provide data for territorial and national reporting requirements.
Most plots will be accessed only by helicopter. At each site, a 400 square metre plot (11.28 m radius) will be established with rebar as a centre post. All trees, shrubs and other vegetation will...

Summary:
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...

This season, a party of two will survey tubes between North Richards Island and Tsiigehtchic during April and from Fort Simpson to the Arctic Coast in July and August. Travel will be by road, small boat on the river and helicopter from Norman Wells and Tutoyaktuk. Access to the sites is always on foot. This year is the seventh annual survey of a network of thaw depth measuring devices (thaw tub...

1994 Summary:
The researcher will collect living plants (Arctic grasses), 6 - 10 species from each collection site. In addition, several plants of each species will be pressed and dried as voucher specimens to be used to check the identification. Photographs of the plants and their habitats will be made. In Ottawa, variations in DNA among different populations and species will be analyzed to study species re...

19931992 Summary:
The researcher will sample a variety of lakes (some 50 lakes altogether) around Inuvik. A hole, approximately 8 inches in diameter, will be bored through the ice in each lake. Using an Ekman sampler, lake bottom sediments (mud) will be collected for analysis in the lab. The researchers will get to each of the lakes bt helicopter and spend approximately 15 to 20 minutes at each lake....

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....

1992198919881987 Summary:
In previous research in the 1970's, experiments and surveys provided information on the recovery rates of vegetation in response to disturbances from human activities. Several predictions about the long-term recovery of vegetation were made at that time. We are now collecting data to determine if these predictions reflect what is actually occurring. This information provides information about l...

19921991 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...

Summary:
The experiment will determine the interacting effects of fire severity, soil moisture and air temperature treatments on the emergence, winter survival and initial growth of treeline and near treeline tree species. The availability and viability of tree seed for successful regeneration of the treeline and near-treeline tree species will also be determined....
