Zusammenfassung:
In September, 1978, ten ponds inhabited by Cladocera were sampled along the coasts of the Strait of Belle Isle. Fourteen out of nineteen species that were found there also occur in Greenland. On the Other hand, a comparison with faunal lists for the island of Newfoundland and several faunal regions of Western Europe, and the ecological distribution of all European Cladocera reveals that the Arctic is settled exclusively by euryecious species, so that the relatively strong "arctic" element within the cladoceran fauna along the Strait of Belle Isle indicates simply the extreme conditions. Macrothrix hirsuticornis Norman and Brady and Daphnia pulex Leydig are new for the island of Newfoundland.
