Ecology of white spruce at the species limit in NWT, Canada
Principal Investigator: Walker, Xanthe J
Licensed Year(s): 2009 2008
Summary: The overall objective of this research is to determine the impact of climate change on the ecological patterns and processes of white spruce trees within the forest-tundra transition zone in the Tuktoyaktuk region of the Northwest Territories, Canada. White spruce reproduction, establishment, and growth will be assessed to determine how these parameters may have changed since they were last measur...

Environmental change in the 20th century, Mackenzie Delta region, Northwest Territories
Principal Investigator: Pisaric, Michael FJ
Licensed Year(s): 2008 2007 2006 2005
Summary: The impact of climate change on forest ecosystems in the Mackenzie Delta is being studied using dendrochronology. Earlier studies indicate a negative relationship between tree growth and summer temperatures. Summer temperatures may be exceeding the physiological threshold of northern trees or perhaps the trees are drought stressed. Manual and automatic dendrometers will be used to measure tree gro...

Autecology of Green Alder in the Mackenzie Delta
Principal Investigator: Lantz, Trevor C.
Licensed Year(s): 2006 2005 2004
Summary: The objective of this research is to explore the influence of temperature and disturbance on green alder by comparing alder characteristics on sites with different average temperatures and disturbance histories. Understanding of factors that influence alder populations today will assist in predicting the likely consequences of rising temperatures and increased disturbance on tall shrubs. A min...

Past climates of ancient forests on Banks Island
Principal Investigator: Williams, Christopher J
Licensed Year(s): 2005 2003
Summary: 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 ...
