Ecology of White Spruce at the Species Limit in North West Canada
chercheur principal: Henry, Greg H R
Année(s) de permis: 2009 2008
Résumé: This license has been issued for the scientific research application #868. The objectives of this research are to determine what changes have occurred in spruce trees near the treeline in response to the warming climate of the Mackenzie Delta region over the past 20-50 years. The researchers will visit sites measured in the early 1990s and repeat the same measurements, which will allow them to ...

Responses of Circumpolar Plant Species and Their Communities To Simulated Climate Change
chercheur principal: Henry, Greg H R
Année(s) de permis: 1994 1993 1992
Résumé: Researchers have established field experiments in 5 plant communities to simulate climate change scenarios (i) no change; (ii) warmer, longer seasons with earlier snow melt; (iii) warmer growing seasons with later snow melt. The temperatures are increased in small open-topped greenhouses and the date of snow melt is changed by adding or removing snow. Tagged plants of the major vascular plant spec...
