Distribution of Dark-Celled Fungal Root Endophytes Along an Arctic to Boreal Latitudinal Gradient
Principal Investigator: Piercey, Melissa
Licenced Year(s): 2000
Summary: Roots of plants inhabiting cold-stressed environments are often colonized by vegetatively reproducing fungi. The researcher will examine the genetic variation within and among populations of Phialocephala fortinii P. along a latitudinal gradient encompassing the boreal, subarctic and arctic zones in Northern Canada. The researcher will travel from Yellowknife to 3 study sites surrounding Great ...

The Effects of UV-B Radiation On the Community of Arctic Lakes
Principal Investigator: Perin, Sofia
Licenced Year(s): 1994
Summary: This study will be done by setting up 6 enclosures in a lake or pond. Two enclosures will be exposed to reduced UV-B levels, two other enclosures will be exposed to ambient UV-B levels, and finally two other enclosures will be exposed to enhanced UV-B levels. Regular measurements will be made of algae and invertebrates biomass, species composition, and pigment; and of algal photosynthesis and end ...

The Creation and Utilization of an Artifical Reef in the Churchill Region
Principal Investigator: Thornton, Sheila
Licenced Year(s): 1990
Summary: The Researcher will create an artifical reef in the Churchill region and develop an arctic ecosystem study site. She will create a species inventory which will involve benthic sampling using SCUBA gear. Species include benthic marine invertebrates, fish and pelagic invertebrates found in 0-20 metres of water....

Biomass estimation for North American Boreal Forests: The first step toward statistically valid global measures.
Principal Investigator: Simpson, Lloyd G.
Licenced Year(s): 1988 1987
Summary: To obtain the first statistically valid estimate of the biomass of the North American boreal forest. To locate sample plots that are randomly located throughout the boreal forest and make simple non-destructive dimensional measurements of trees and shrubs....
