Environmental change in the 20th century, Mackenzie Delta region, Northwest Territories
chercheur principal:
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...
