Abstract: | Summary Forty taxa of testate amoebae were found in 15 aquatic samples collected in East Greenland (Angmasssalik Region), Jan Mayen and N.W. Spitsbergen. The number of species per sample is rather small, and the contribution of strictly aquatic species to the fauna is limited. A geographical shift in the importance of some genera can be demonstrated. Centropyxis aerophila and Paraquadrula irregularis are two of the most frequent species. The first-named is characteristic for acidoligotrophic waters, while the latter belongs to an alkaline-mesotrophic community. A third community is named after the commonest species, Trinema lineare. It seems to prefer a somewhat intermediate type of water. |
