Testate amoebae communities from terrestrial moss habitats in the Zackenberg area (North-East Greenland)

In total 45 taxa, belonging to 12 genera, were recorded from moss samples, collected in Zackenberg (Northeast Greenland). The highest number of taxa b elongs to the genera Nebela and Euglypha. The genus Trinema showed the high est mean relative abundance, this is due to Trinema lineare Penard. Other i mportant genera were Euglypha, Corythion, Assulina and Nebela. A hierarchic -agglomerate cluster analysis reveals 2 assemblages. The first assemblage h as higher abundance of taxa typical for wetter conditions (Trinema lineare Penard, Euglypha rotunda Wailes and Centropyxis aerophila Deflandre). Taxa typical for drier conditions Like Assulina muscorum Greeff, Corythion dubiu m Taranek, Nebela collaris Leidy and Nebela minor Penard were found in the other assemblage. These assemblages are also known from other sites in the Arctic e.g. the Sondre Stromfjord Region (West-Greenland) and Devon Island (Canadian Arctic).
