Landscape scale flooding in the Great Slave Lake Plain
chercheur principal: Armstrong, Terry
Année(s) de permis: 2014 2013 2012 2011 2010
Résumé: The objectives are to draw together multiple sources of information so that we may (1) examine change in lake area in this ecoregion, (2) assess amount of meadow habitat lost to rising water levels in core bison range, (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change, (4) determine a way to document and integrate local and traditional kn...

Environmental change in the 20th century, Mackenzie Delta region, Northwest Territories
chercheur principal: Pisaric, Michael FJ
Année(s) de permis: 2008 2007 2006 2005
Résumé: 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...

The relation between climate and abundance cycles in barrenland caribou herds, NWT.
chercheur principal: Zalatan, Rebecca
Année(s) de permis: 2005
Résumé: Caribou populations fluctuate over long time spans. However, long-term records of population cycles are scarce. Dendrochronology and hoof scars left on the surficial roots of spruce trees across caribou trails will be used to reconstruct the population...

Analaysis of Bathurst Caribou Herd Dynamics Using a Proxy Indicator
chercheur principal: Zalatan, Rececca
Année(s) de permis: 2004 2003
Résumé: Caribou populations fluctuate over long time spans. However, long-term records of population cycles are scarce. The population dynamics of the Bathurst and Beverly caribou herd across the Northwest Territories will be reconstructed using two proxy indic...

Extensive Dendrochronological Reconstruction of Temperature in the Northern Hemisphere: North American Boreal Zone
chercheur principal: Jacoby, Gordon C.
Année(s) de permis: 1994 1989
Résumé: 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....
