Expedition Fiord: Sedimentary Environment Since the Ice Ages.
chercheur principal: Gilbert, Robert
Année(s) de permis: 1993 1992 1991 1990 1988
Résumé: The researcher wishes to recover cores of sediment about 2 meters long from the sea floor near Expedition Fiord. These cores will provide confirmation of past acoustic surveys and direct evidence of changes in the physical and biological environment of the fiord. Seven sites in the fiord will have sediment cores removed....

The relationship between postglacial history and the modern genetic and morphologic diversity of jackpine (Pinus banksiana) in the Mackenzie River valley
chercheur principal: MacDonald, Glen M
Année(s) de permis: 1989 1988
Résumé: to obtain lake sediment cores, samples of pine needles, cones and seeds, and tree-ring cores from 10 sites along the Mackenzie River between Norman Wells and Fort Simpson in order to document the chronology of pine migration into the Mackenzie Valley following the last ice-age and to test hypotheses regarding postglacial history of northern plants and distributions of genetic diversity...

Licence #7118
chercheur principal: Green, John M.
Année(s) de permis: 1987
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....

Treeline plant population response to postglacial climatic change in North Central Canada.
chercheur principal: MacDonald, Glen M
Année(s) de permis: 1987
Résumé: To use fossil pollen and plant macrofossils from small lakes to reconstruct the response of plant populations in the treeline zone to climatic change. Modern pollen surface samples from small lakes in the treeline zone will be collected to aoid in the interpretation of the fossil pollen samples. The study area will include the boreal forest, forest-tundra and tundra zones near Yellowknife (115 W...
