Chercheur Scientifique

Chris Edge est chercheur scientifique au Service canadien des forêts de Ressources naturelles Canada et professeur auxiliaire au Département de biologie de l’Université du Nouveau-Brunswick. La recherche de Chris vise à comprendre comment les écosystèmes forestiers réagissent aux perturbations à de grandes échelles spatiales et temporelles. Cette recherche nécessite des expériences en laboratoire, en mésocosme et dans l’ensemble de l’écosystème, combinées à la modélisation des populations et à l’écologie théorique. Le but ultime de la recherche de Chris est d’éclairer la gestion durable des forêts à l’échelle des paysages.
