Forest Research in the Mackenzie River Delta
chercheur principal: Johnson, Art
Année(s) de permis: 2005
Résumé: Researchers are currently working on a project at Banks Island where they will measure stumps and logs of 3-million-year-old trees and attempt to understand the species that grew there, how tall the trees were, their diameters and the annual production of wood and foliage. Researchers know the Banks Island trees were spruce, larch and pine. To accurately determine what the ancient trees looked l...

Past climates of ancient forests on Banks Island
chercheur principal: Williams, Christopher J
Année(s) de permis: 2005 2003
Résumé: The objective of this project is to make detailed measurements of fossil plants that grew at high latitudes between 12 and 2 million years ago. The researchers will use these and previously obtained data to test the hypothesis that until about 28 million years ago arctic wetland forests were high biomass forests dominated by deciduous conifers, but by 12 million years aga, these were replaced by ...

Ecophysiological Reconstruction of High Latitude Fossils
chercheur principal: Jagels, Richard
Année(s) de permis: 2000
Résumé: The NWT component of this study is to examine how the anatomical features of wood from the genus Larix, vary with changes in latitude. This will be compared to work done on Axel Heiberg Island, Nunavut where a fossil forest of mummified wood approximately 45 million years old was found. Certain features of wood can provide clues to assess winter temperatures but these features vary with latitude....
