Principal Investigator:Eshenroder, Randy Licenced Year(s):
The objective of this study is to determine whether a deep-water type of lake trout resembling the “humper” of Lake Superior lives on offshore reefs in Great Slave Lake, as they do in Lake Superior. The researchers have also found humper-like trout in Great Bear Lake and in Lake Mistassini, Quebec. In Great Slave Lake, the researchers intend to target offshore reefs surrounded by deep water (deepe...

The objective of this study is to establish a baseline collection of tissue and fin samples from broad whitefish that will eventually be used for phylogeographic analysis and the classification of their genetic population structure.
Local Gwich’in and Inuvialuit fishermen will be asked, on a volunteer-only basis, to collect fins or tissue samples from broad whitefish caught during the subsisten...

The research goal is to determine whether the same genes control similar skeletal change in different populations and species. Stickleback fish are ideal subjects for this study because different freshwater populations show morphological differences in s...
Principal Investigator:Piercey, Melissa Licenced Year(s):
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 ...
Principal Investigator:Line, Jennifer Licenced Year(s):
This research will contribute to an increased understanding of ecological integrity in Nahanni National Park, provide information on the importance of glacial refugia as banks of genetic diversity and highlight the value of genetic diversity as an indicator of ecological integrity. The researcher will be transported to sampling sites within the park by Parks Canada staff (plane, helicopter). At...
Principal Investigator:Hebert, Paul Licenced Year(s):
Our research will involve the survey of zooplankton communities in lakes and ponds of the Mackenzie Delta area (Inuvialuit private lands). Samples will be collected by either wading in ponds or by towing at net behind a float equipped helicopter. Samples will be frozen in liquid nitrogen, and subsequently examined for genetic variation. Our work aims to establish the species diversity of zoopla...

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...
Principal Investigator:Babaluk, John Licenced Year(s):
This is a continuing project to survey fish populations of lakes and rivers. In the past population studies have been conducted in the Fish and Raddi lakes, the Sachs River and the Benard River. This year Middle and Kuptan lakes will be surveyed and if there is time Capron and Swan lakes may also be surveyed. The project will also continue studies on genetic and morphological variation in Arcti...
Principal Investigator:Hebert, Paul D.N. Licenced Year(s):1994
The researcher and his team will measure the amount of genetic diversity in arctic zooplankton, determine distributions and numbers of species in arctic lakes and ascertain factors limiting species distributions in the arctic....
Principal Investigator:Eger, Judith Licenced Year(s):
The investigators will study the chromosomal and genetic variation in collared lemmings to assess the effect of isolation of different populations in glacial refugia. They will compare this species with the brown lemming....
