Factors affecting the structure of epiphytic gastropod communities in the St. Lawrence River (Quebec, Canada)

  title={Factors affecting the structure of epiphytic gastropod communities in the St. Lawrence River (Quebec, Canada)},
  author={Beno{\^i}t Vincent and H{\'e}l{\`e}ne Rioux and Michel Harvey},
A study of epiphytic gastropods associated with two submerged macrophytes (Myriophyllum spicatum and Vallisneria americana) was conducted at a soft and at a hard water site in the St. Lawrence River during two non-consecutive years in order to compare effects of macrophyte species and biomass, site and year in gastropod community structure. There was no effect of macrophyte species on total gastropod abundance nor on gastropod diversity, and few gastropod species showed a marked preference for… CONTINUE READING
