Research

The Canada Research Chair in integrative biology of nordic flora study ecological, biogeographical and evolutionary responses of the arctic-boreal flora to the environmental variations induced by historical (Quaternary) and current (anthropogenic) climate changes. The integrative approach uses many tools, including field work, molecular biologe (population genetics/genomics), paleoecology and modelisation. The conceptual frame allows the joint study of the various responses in order to acquire a global perspective, from genes to ecosystems.
