Mathieu Cusson, professor-researcher in the marine ecology laboratory, supervises a number of Canadian and international students at all levels of study (bachelor's, master's and doctorate). Most of their work takes place in the marine mediolittoral of the St. Lawrence. We study the links between diversity and stability in the functioning of marine coastal ecosystems. We are interested in identifying the effect of multiple disturbances (environmental and human-induced) on biodiversity and functioning, and of energy flows at the scale of biological communities and ecosystems. 

Our key words: Spatial and temporal analysis, marine benthos, community dynamics, functional ecology, numerical ecology, algal and invertebrate macrobenthos, biodiversity measurements, natural and human disturbances, primary and secondary production, ecosystem stability (resilience/resistance).
