Marie-Josée is an ecologist by training. She has four main research areas: spatial ecology, forest ecology, landscape ecology and spatial statistics. Her research program studies the effects of global changes (landuse and climate) on species spatial dynamics at the landscape and the geographical range levels, both in multiuse forested ecosystems and aquatic networks to maintain biodiversity and species conservation. Through her work, Marie-Josée Fortin, Canada Research Chair in Spatial Ecology, provides ecologists with novel network analytical methods that can be used to propose management strategies to facilitate species dispersal in fragmented landscapes, to maintain the resilience of ecosystem services, or to prevent disease spread.
