Phylogeography and Genetic Population Structure of Broad Whitefish (Coregonus nasus) in the Mackenzie Delta and River and Surrounding Area, Northwest Territories
chercheur principal:
Année(s) de permis: 2005
Résumé: 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...


Genetic Diversity in the Biota of Arctic Lakes
chercheur principal:
Année(s) de permis: 1997
Résumé: 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...


Hybridization and genetic variation in arctic grasses: molecular, morphological and ecological evidence
chercheur principal:
Année(s) de permis: 1997 1995 1994
Résumé: 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...
