Résumé: The primary objective of this project is to collect B. chariclea arctica from sites in the Yukon and Northwest Territories. A network of haplotypes will be constructed, based on the mitochondrial cytochrome c oxidase subunit I (COI) gene, and a mismatch analysis will be performed to determine if genetic structure has been influenced by a sudden expansion in population size or long term stability. ...

Résumé: In this project, the ancestry and history of the Aboriginal populations of the NWT will be explored through the analysis of genetic diversity in these communities. Through this DNA analysis, the origin and diversity of these aboriginal people will be investigated and their relationship to other aboriginal peoples of Canada and Alaska will be assessed. Overall, this approach will generate new insi...

Résumé: The primary objective of the fieldwork is to collect small samples of seed from grass species in six primary Genera: Festuca, Poa, Deschampsis, Leymus, Elymus and Alopecurus. Other species may be collected. Wild mustard species (Crucifer species) will also be collected. The collections will be compared visually and genetically to other collections of the same or closely related species from Alaska...

Résumé: The researcher will be collecting lake trout and/or arctic charr from lakes in the vicinities of Hay River, Inuvik, Paulatuk and Tuktoyaktuk in order to examine the distributions of these species. Samples of liver and muscle tissue will be collected from these fish for genetic analyses: this research will provide information about how different populations are related to each other (i.e., their o...

Résumé: The Researcher and team will apply new tag technology and DNA analysis to a study of site tenacity and industrial disturbance of bowhead whales. They will test the feasibility of using sonic tags to track bowheads underwater and will be testing sampling methods for collecting skin from live whales for DNA analysis....

Résumé: To continue the ongoing study designed to investigate the postglacial dispersal patterns of freshwater and anadromous fishes by determining genetic relationships between fish populations inhabiting the rivers. Tissue samples will be collected and the genetic variations will be determined through analysis for selected proteins....

Année(s) de permis: 1987
Résumé: To re-define the classification of the Potentilla nivea L. complex using methods based on modern plant systematics. Some of the techniques and methods to be used will include chromosome counts, pollen and seed viability tests, guard cell measurements, SEM of pollin exine variations, flavonoid chemistry and numerical analyses. Attempts will be made to determine if correlations exist between morph...
