PRESENCE OF ALGAE IN FRESHWATER ICE COVER OF FLUVIAL LAC SAINT‐PIERRE (ST. LAWRENCE RIVER, CANADA) 1
Winter ice cover is a fundamental feature of north temperate aquatic systems and is associated with the least productive months of the year. Here we describe a previously unknown freshwater habitat for algal and microbial communities in the ice cover of the freshwater St. Lawrence River, Quebec, Can...
