THE BENTHIC ALGAE OF SOUTHERN BAFFIN ISLAND. I. EPIPELIC COMMUNITIES IN RIVERS 1
SUMMARY The epipelic algae found in 9 rivers of southern Baffin Island were investigated during the 1972 growing season. The overall assemblage consisted of 240 taxa, of which 200 belonged to the Bacillariophyta and, only 17 to the Chlorophyta. Members of the Bacillariophyta accounted for S7–100% by...
