Abstract

The paper reports the first comprehensive study of microalgal species composition in four lakes of Volhynian Polissya (northwestern Ukraine), in which 271 species (279 intraspecific taxa) of 11 microalgal phyla were identified. Four dominant phytoplankton assemblages were determined for each lake. Bacillariophyta and Charophyta formed more than half (59.2%) of the taxonomic list, accounting for 94 and 66 species respectively. Desmidiaceae was the most diverse family, with 44 species (47 intraspecific taxa) of microalgae. The four lakes are highly dissimilar in species richness and composition, having only 8 (2.9%) species in common. Lake Cheremske had the highest number of algal species – 137 (144). Lake Bile, Lake Somyne and Lake Redychi were much less diverse, with 105, 79 (80) and 75 (78) species respectively. Morphological descriptions, original micrographies and figures are presented for a number of species, including some not previously documented in Ukraine: Chromulina cf. verrucosa G. A. Klebs, Eunotia myrmica Lange-Bert. and E. tetraodon Ehrenb. The lakes, which are almost pristine or are recovering, maintain diverse and valuable algal floras, making them important sites in the Pan-European ecological network.
乌克兰西北部受保护湖泊的微藻
本文首次对乌克兰西北部Volhynian Polisya四个湖泊的微藻物种组成进行了全面研究,共鉴定出11个微藻门的271种(279个种内分类群)。为每个湖泊确定了四种主要浮游植物组合。Bacillarophyta和Charophyta占分类列表的一半以上(59.2%),分别占94种和66种。Desmidiaceae是最具多样性的科,有44种(47个种内分类群)微藻。这四个湖泊的物种丰富度和组成极不相同,只有8个(2.9%)物种是共同的。切伦斯克湖的藻类种类最多,为137种(144种)。比尔湖、索米恩湖和雷迪奇湖的多样性要低得多,分别有105种、79种(80种)和75种(78种)。提供了许多物种的形态描述、原始显微照片和数字,包括一些以前在乌克兰没有记录的物种:铬藻(Chromulina cf.verrucosa G.a.Klebs)、Eunotia myrmica Lange Bert。和E.tetraodon Ehrenb。这些湖泊几乎是原始的或正在恢复的,保持着多样而有价值的藻类群落,使其成为泛欧生态网络中的重要地点。
