摘要：

Three occurrences of the macroalga Prasiola fluviatilis (Sommerf.) Aresch. were recorded after the examination of 32 stream segments from the Ellesmere Island National Park Reserve (81-degrees-23'N) in the High Arctic of Canada. The collection sites were small (second-third order) glacial melt streams characterized by pH 7.3-8.2, specific conductance of 52-159 muS.cm-1, low ion levels, extremely low nutrient levels, and the lack of other prominent macroalgae. These occurrences confirm the reported circumpolar distribution of the species.
