Gerasimova E.A., Plotnikov A.O. BIODIVERSITY OF AMEBOIDAN PROTISTS IN SALINE WATER BODIES OF ORENBURG REGIONBiodiversity of 16 species of unicellular ameboidan protists (Heterophrys marina, Polyplacocystis coerulea, Pterocystis pinnata, Heteroraphidiophrys australis, Raineriophrys erinaceoides, Raineriophrys raineri, Choanocystis ebelii, Choanocystis perpusilla, Choanocystis pelagica, Acanthocystis astrakhanensis, Acanthocystis dentata, Acanthocystis myriospina, Acanthocysti nichollsi, Acanthocystis pectinata, Acanthocystis taurica, Acanthocystis turfacea) in ecosystems of saline water bodies with salinity 2–22š‰ of Orenburg region was studied. Twelve species of protists (P.špinnata, R.šraineri, C.šebelii, C.šperpusilla, C.špelagica, A.šastrakhanensis, A.šdentata, A.šmyriospina, A.šnichollsi, A.špectinata, A.štaurica, A.šturfacea) were revealed for the first time in ecosystems of saline and brackish continental water bodies of Russia. Seven species (P.špinnata, R.šraineri, A.šdentata, A.šnichollsi, A.špectinata, A.štaurica) were described previously as freshwaters; based on our data it described as euryhaline. Nine cenrtohelidian species (P.špinnata, R.šraineri, C.šebelii, C.šperpusilla, C.špelagica, A.šastrakhanensis, A.šnichollsi, A.štaurica, A.šturfacea) was revealed for the first time in Orenburg region, three of these (P.špinnata, C.šebelii É C.špelagica) are new for heliozoans fauna of Russia. Data on mineralization of the studied biotopes and scanning electron micrographs of heliozoan are presents in the paper.Key words: Centrohelid heliozoa, biodiversity, saline water bodies.
