Long-term forest-tundra disturbance research
chercheur principal:
Année(s) de permis: 1993 1992 1989 1988 1987
Résumé: In previous research in the 1970's, experiments and surveys provided information on the recovery rates of vegetation in response to disturbances from human activities. Several predictions about the long-term recovery of vegetation were made at that time. We are now collecting data to determine if these predictions reflect what is actually occurring. This information provides information about l...

Climate change and postglacial paleoenvironmental history of peatlands in the Mackenzie Delta area
chercheur principal:
Année(s) de permis: 1993 1992
Résumé: This research is part of an international project that is aimed at documenting the history of changes in the treeline during the Holocene era. While much is known about the environment and climate of this era, little is known about the development of peatlands during this time. I will collect data on peat layering, pollen and fossils in order to determine how the peatlands developed during this ...

Mackenzie Basin Impact Study: Land Assessment
chercheur principal:
Année(s) de permis: 1993 1992
Résumé: The Mackenzie Basin Impact Study will assess the potential impacts of global climatic change on the region. The component on land assessment will determine possible changes in land capability. Information on resource management goals is needed so that the study can can assess whether changes in land capability might lead to conflicts over land use....

Peat Plateau Collapse and Climate Change
chercheur principal:
Année(s) de permis: 1992
Résumé: The research will examine permafrost-containing peat plateaus that have burned during severe fires to determine the features of subsidence (decrease) and the rate of subsidence....

Vegetation Response to Global Warming in the Mackenzie River Basin: Interations Between Northern Boreal Forests, Wetlands and Regional Hydrology
chercheur principal:
Année(s) de permis: 1992
Résumé: The Researcher will map the present distribution of boreal and subarctic wetlands in the Mackenzie River Basin. Wetland vegetation and water chemistry will be described for areas immediately surrounding permanent weather stations. The ecological relationships between climate, wetland water chemistry and wetland species distribution will be analyzed. A predictive indicator model will be built to pr...

International Cryosol Tour
chercheur principal:
Année(s) de permis: 1991
Résumé: This tour and the associated meetings will focus on the genesis, classification and management of permafrost soils (Cryosols) and the possible effect of climate change on these soils....
