Summary:
The objective is to increase knowledge of bryophytes (e.g., mosses, liverworts) and (incidentally, where possible) lichens in the Northwest Territories.
Waterfall areas can offer a wide diversity of microhabitats (featuring a large variety of substrates, moisture and light levels, and exposures) within a relatively small area. Bryophyte species and communities are often associated with specific...

199219911990 Summary:
Project 1: Small samples of lichens will be collected from approximately 20 sites located along the Hood River and analyzed for contaminants. Lichens are good indicators of the types of air-borne contaminants that have been carried north to the arctic since they absorb their nutrients from the air. Project 2: The researcher will examine plant communities along the Hood River in order to study th...

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....
