Treeline Dynamics in Western Canadian Arctic
chercheur principal:
Année(s) de permis: 2009 2008
Résumé: 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. Annual tree rings represent a growth response to local climate. Wide growth rings represent good growing conditions, and nar...

Photosynthetic Efficiency and Water Relations in Boreal Conifers under 24 Hour Environmental Light Conditions
chercheur principal:
Année(s) de permis: 2007
Résumé: The objective of this project is to examine the environmental thresholds to the successful establishment of a boreal (high latitude) conifer forest by measuring photosynthetic rates in conifer seedlings. Climate change has the potential to shift southern commercial tree species and treelines northward with implications for existing ecosystems and future economic development. The project’s goal ...

Fire Severity and Growth of Treeline Tree Species: Climate Change Implications
chercheur principal:
Année(s) de permis: 1992
Résumé: The experiment will determine the interacting effects of fire severity, soil moisture and air temperature treatments on the emergence, winter survival and initial growth of treeline and near treeline tree species. The availability and viability of tree seed for successful regeneration of the treeline and near-treeline tree species will also be determined....

Climatic Change at the Forest-Tundra Boundary
chercheur principal:
Année(s) de permis: 1992 1991 1990
Résumé: To determine the maximum size of treeline tree species in a burned and unburned valley in the Caribou Hills, the mass of standing trees on different slopes and aspects will be estimated and related to the energy input. In 1992 the plots prepared in 1990 and planted and seeded in 1991, will be revisited and measurement of growth for the second growing season will be taken....
