Black Spruce Fertility at the Arctic Treeline
chercheur principal:
Année(s) de permis: 2009
Résumé: The research objective is to show that the fertility of black spruce (Picea mariana) in the Arctic is limited by the amount of pollen in the surrounding air. After snowmelt, the researchers will choose unburned black spruce “islands” at different distances from the perimeter of the 1999 Lynx Creek fire. Subsequently, as the developing black spruce pollen cones become easy to see, they will remo...

Treeline Dynamics in the Western Canadian Arctic
chercheur principal:
Année(s) de permis: 2009 2008
Résumé: This licence was issued for the application # 836. The project will examine past tree growth patterns at the northern treeline in Western Canada as a baseline to predict future growth responses to climate change. Additionally, the researchers will examine tree regeneration and plant associations at the northern treeline. Growth-ring analyses will be conducted in mature treeline populations....

Canadian Intersite Decomposition Experiment
chercheur principal:
Année(s) de permis: 1993
Résumé: Forestry researchers tend to study in detail their local forests yet for major issues such as global warming, it is necessary to conduct research over larger areas to understand impacts on Canadian forests and industry. This study attempts to better describe rates of decomposition and nutrient mineralization across Canadian forests in order to understand how forests are supplied with nutrients fo...

Climatic Change at the Forest/Tundra Boundary
chercheur principal:
Année(s) de permis: 1992 1991 1990
Résumé: The Researcher and his team will seed and plant plots prepared in 1990. They will determine the germination rate, establishment and the annual growth of the seedlings. The measurements will be related to the energy input which influences these microsites....
