A preliminary annotated checklist of Cladocera (Crustacea) of Ukrainian Carpathians
Abstract
53 species of Cladocera are known in the Ukrainian Carpathians. The total number of lenthic reservoirs in the region is more than 375 and 13 big rivers by the results of own researching and literature data. For the first time there were investigated 310 of lenthic water bodies. Chydorus sphaericus (O. F. Müller, 1776) is the most common species in this region. Two species, C. sphaericus and Daphnia obtusa Kurz, 1874, were found over 1900 m a.s.l. There are 11 species in the alpine reservoirs (over 1800 m a.s.l.), 22 species – in subalpine reservoirs (1500–1800 m a.s.l.). There are known a 51 species from altitude 200–1500 m a.s.l., zones of the coniferous and mixed forests. The Daphnia longispina (O. F. Müller, 1776), D. obtusa, Simocephalus vetulus (O. F. Müller, 1776), Alona affinis (Leydig, 1860), Alona quadrangularis (O. F. Müller, 1776), Alonella excisa (Fischer, 1854), Peracantha truncata (O. F. Müller, 1785), Bosmina longirostris (O. F. Müller, 1776) were found in the majority mountains massifs and rivers basins. This species are counted as usually for the Ukrainian Carpathians. The three species, Daphnia rosea Sars, 1862, D. obtusa, Alona protzi Hartwig, were found for Ukraine only in Carpathians mountains. The Ceriodaphnia megalops Sars, 1890, Simocephalus expinosus (Koch, 1841), Moina macrocopa (Straus, 1820) were found for the first time on the territory of Ukrainian Carpathians and A. protzi for the first time on Ukraine. This mountain territory is a natural eastern area border for A. protzi and D. obtusa. The 25 percents of species enter the territory of the Carpathians from the valleys of the lowlands rivers. Fauna of Cladocera was investigated for the biggest lakes and reservoirs, small part of ponds on the fish farms, a few beds and floodplains of the biggest rivers, lenthic water bodies some of the highlands massifs and some of the nature protected areas of the Ukrainian Carpathians during the latter 140 years. These are more less 20 percents from all existing planktocoenoses number. We think the noted species diversity is twice fewer than real.
