The relationship between postglacial history and the modern genetic and morphologic diversity of jackpine (Pinus banksiana) in the Mackenzie River valley
Principal Investigator: MacDonald, Glen M
Licensed Year(s): 1989 1988
Summary: 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...

Treeline plant population response to postglacial climatic change in North Central Canada.
Principal Investigator: MacDonald, Glen M
Licensed Year(s): 1987
Summary: 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...
