ВИДОВИЙ СКЛАД і ПОШИРЕННЯ ГОЛИХ АМЕБ (TUBULINEA, DISCOSEA, HETEROLOBOSEA) У ВОДОЙМАХ ЛЬВІВСЬКОЇ ОБЛАСТІ

Abstract

The result of research conducted in the water bodies of Lviv region identified 21 species of naked amoebae that belong to 3 classes, 12 families and 13 genera. The are species: Deuteramoeba mycophaga (Pussard, Alabouvette, Lemaitre & Pons, 1980) Page, 1988, Saccamoeba stagnicola Page, 1974, Saccamoeba limax (Dujardin, 1841) Page, 1974, Saccamoeba limna Bovee, 1972, Hartmannella cantabrigiensis Page, 1974, Echinamoeba exundans Page, 1975, Rhizamoeba flabellate Goodey, 1914, Vexillifera sp., Korotnevella sp., Vannella lata Page, 1988, Vannella cirrifera (Frenzel, 1892) Page, 1988, Cochliopodium sp., Mayorella cantabrigiensis Page, 1983, Mayorella bigemma Schaeffer, 1926, Mayorella leidyi Bovee, 1970, Mayorella sp. (1), Thecamoeba striata (Penard, 1890) Schaeffer, 1926, Thecamoeba quadrilineata (Carter, 1856) Lepsi, 1960, Vahlkampfia sp. (1), Acanthamoeba sp. (2), Acanthamoeba sp. (1). Comparing the specific lists of naked amoebae in different regions of Ukraine, we have found that the specific composition of these opposites in L’viv region is most similar to Zhytomyr region (55 %), and the least similar to Sumy region (36 %). According to the results of cluster analysis, the faunal complexes of amoebae in Ukraine are united into two clusters. In the first cluster there are complexes of Kiev, Lviv, Zhytomyr and Rivne regions, and in the second one – Sumy region. The active response of aquatic environment, concentration of dissolved oxygen in the water and organic substances have different effects on the distribution of amoebae in the water bodies of Lviv region. Allocated 6 ecological groups of protozoa: evian, stenon, eriksen, lanoxin, those marked within the narrow range of permanganate oxidation values and within the broad one. New to the fauna of Ukraine were amoeba S. limna , R. flabellata , E. exundans , V. cirrifera , Acanthamoeba sp. (2). We found two amoebae of the genus Acanthamoeba Volkonsky, 1931, which are clearly distinguished from each other according to the morphological characteristics ( Acanthamoeba sp. (1) and Acanthamoeba sp. (2)). However, for final species identification of amoebae of the genus Acanthamoeba conduct additional studies involving data on the optimal conditions of cultivation, virulence and analysis of enzymes.
