Recherche

La Chaire de recherche du Canada en biologie intégrative de la flore nordique étudie les réponses écologiques, biogéographiques et évolutives de la flore arcto-boréale aux variations environnementales induites par les changements climatiques historiques (du Quaternaire) et actuels (d’origine anthropique). L’approche intégrative emploie plusieurs outils incluant notamment l’écologie de terrain, la biologie moléculaire (génétique/génomique des populations), la paléoécologie et la modélisation. Le cadre conceptuel permet l’étude conjointe des diverses réponses afin d’acquérir une perspective globale, du gène à l’écosystème.
