The species composition of naked amoeba in epiphytic mosses of Zhytomyr region

Abstract

From epiphytic habitats of Zhytomyr region we identified 16 species of naked amoebae. This species: Vahlkampfia sp. (1), Saccamoeba stagnicola (Page, 1974), Saccamoeba sp. (1), Cashia limacoides (Page, 1974), Korotnevella sp. (1), Vexillifera sp., Ripella platypodia (Smirnov, Nassonova, Chao et Cavalier-Smith, 2007), Ripella sp., Cochliopodium sp. (1), Mayorella cantabrigiensis (Page, 1983), Mayorella sp., Thecamoeba striata Penard, 1890, Thecamoeba sp., Stenamoeba stenopodia (Page, 1969; Smirnov et al., 2007), Acanthamoeba sp. (1), Stygamoeba polymorpha (Sawyer, 1975). The most common were the amoebae Cochliopodium sp., Acanthamoeba sp. (1), S. stenopodia, Vexillifera sp., the least common – T. striata, R. platypodia, Mayorella sp., S. stagnicola, Saccamoeba sp. (1), S. polymorpha. On the species composition of the naked amoebae in epiphytic habitats Zhytomyr region is affected by the humidity of the substrate: a decrease in humidity reduced the species richness of amoebae. The connection of the species composition of amoebae with height above the ground with increasing height above the ground decreases the species composition of amoebae. At the levels of 0–1,5 m, the most common amoeba occur (S. stenopodia, Cochliopodium sp. (1), M. cantabrigiensis, Acanthamoeba sp. (1)), at a height of 1–1,5 m, most amoeba disappear and the least appears common view of Thecamoeba sp. In wet mosses dominating species Vahlkampfia sp. (1), Vahlkampfia sp. (2), R. platypodia, S. stenopodia, Cochliopodium sp. (1), M. cantabrigiensis, Acanthamoeba sp. (1), dry epiphytes of the study area met C. limacoides, Korotnevella sp. (1), S. polymorpha. The most heterogeneous complexes of the wet habitats, while dry – fairly uniform. We identified all species can be considered everybody, meet as in mosses and aquatic and soil habitats.
