2012201120102009 Summary:
The objectives of this research are to examine the impacts of climate and environmental change on freshwater ecosystems in the Inuvik region across a variety of spatial and temporal scales. Specifically, the team is examining the impacts of permafrost degradation and subsequent thaw slumping on freshwater ecosystems and the impact of climate change on tree growth in the Mackenzie Delta.

2008 Summary:
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...

2004200320022001 Summary:
Northern forests are closely connected to the issue of global warming because they are likely to absorb much of the carbon dioxide that is emitted into the air by humans. The amount that these forests absorb, however, is not clear. The main objectives of the 2005 field season are to collect data on the annual growth of fine roots, and to further examine the rate of soil respiration. Both of these...

Summary:
There are three main parts in the researchers' project: 1) investigating changes in vegetation cover in the Inuvik region during the past 10,000 years using fossil pollen and stomata preserved in lake sediment; 2) investigating the importance of disturb...

Summary:
The research team consisting of forest ecologists, will go to Wood Buffalo National Park by air. A rental vehicle will also be used in the field. Most activities will consist of re-measuring jack pine stands that were examined in 1992. Various kinds of measuring tapes and a pole are used to obtain data. A few stands will be studies by taking stem samples for examination of tree rings and tree g...

Summary:
As part of an on-going study, this research will involve collecting cores from trees located in the Campbell-Dolomite Uplands (near Campbell Lake). This data will be added to data collected in other locations (past studies) in order to determine how past climate has influenced the growth of trees (as indicated by tree rings within the tree trunk). The research is helpful in trying to understand ...

Summary:
The researcher and her team will glean physiological rates and relationships for tree growth from the literature and substitute the data into a functional model, which will be calibrated against intensive sampling within WBNP over dry, mesic and wet landscapes....

19911990 Summary:
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....

Summary:
The object of this research is to reconstruct past climate in order to understand how the climate system works, and what past natural variations may be expected based upon this information. This project is to sample old-aged trees and to assemble enough coverage to reconstruct regional and Hemispheric temperatures for the most recent centuries....
