My M.Sc. thesis examined the distribution, abundance, and condition of the Asian clam Corbicula fluminea in the discharge plume of a nuclear power plant (Gentilly-2) in the St-Lawrence River. The Gentilly site is the most northern limit reported for this warm-water species, which is considered to be one of the most invasive freshwater molluscs in the world. Our manuscript entitled “Distribution, abundance and condition of an invasive bivalve (Corbicula fluminea) along an artificial thermal gradient in the St. Lawrence River,” was published in Aquatic Invasions.

Also within the thermal plume, we discovered new species of Bryozoans: Lophopodella carteri Hyatt, Urnatella gracilis Leidy, and Lophopus crystallinus (Pallas). These species are thought to be nonindigenous in the St. Lawrence River. Our manuscript entitled “Cryptic invaders: nonindigenous and cryptogenic freshwater Bryozoa and Entoprocta in the St. Lawrence River,” was published in Biological Invasions.
