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...
