Abstract

This study considers the algal flora of Lake Zasvitske (Rivne region, Ukraine). The author identifies 61 species of algae presented with 62 intraspecific taxa subdivided into nomenclatural types that belong to 8 divisions, 13 classes, 24 orders, 34 families and 51 genera. The paper demonstrates that Bacillariophyta, Chlorophyta, Cyanobacteria and Streptophyta play a significant role in lake phytoplankton development. According to the population, the Shannon diversity index varies from 2.13 bit/spec. (October) to 3.89 bit/spec. (July), and according to biomass this index varies from 1.63 bit/spec. (June) to 4.10 bit/spec. (July). In the lake phytoplankton, polydominant structure prevails. In Lake Zasvitske the phytoplankton core is developed with planktonic-benthic and planktonic species, slow-flowing species according to water saturation with oxygen and rheophilicity, indifferent species in relation to the density, pH level of the environment and water temperature, mesoeutrophic ones and species with wide amplitude according to the trophic level. Eurysaprobes (according to the Watanabe system) and beta-mesosaprobionts (according to the Pantle-Buk system as modified by Sladecek) are predominant among indicator species of organic water pollution.

乌克兰扎斯维茨克湖(Rivne地区)藻类区系的季节动态

这项研究考虑了Zasvitske湖的藻类植物群(Rivne地区，乌克兰)。共鉴定出藻类61种，种内分类群62个，分属于8科13纲24目34科51属。本文论证了硅藻门、绿藻门、蓝藻门;和链藻在湖泊浮游植物的发育中起着重要作用。根据种群的不同，香农多样性指数从2.13 bit/spec不等。(10月)至3.89位/规格。(7月)，根据生物量，该指数在1.63 bit/spec之间变化。(6月)至4.10位/规格。(7月)。湖泊浮游植物以多优势结构为主。Zasvitske湖浮游植物核心发育有浮游-底栖物种和浮游物种，含氧饱和度和亲流变性决定的慢流物种，密度、环境pH值和水温决定的淡漠物种，中富营养化物种和营养水平决定的宽振幅物种。Eurysaprobes(根据Watanabe体系)和β -介生菌(根据Sladecek改良的Pantle-Buk体系)是有机水污染的主要指示物种。

期刊介绍： The algae are heterogeneous assemblage of phytosynthetic organisms, one of the most vast and diverse groups of ancient photoautotrophic pro- and eukaryotic organisms (about 30 000 known species). They are micro- and macroscopic, unicellular, colonial, or multicellular, mobile and immobile, attached and free-living. Algae are widespread in water and soil habitats, at different geographic latitudes, and on all continents. They occur in waters with different degrees of salinity, trophicity, organic matter, and hydrogen ions, and at various temperatures. They include planktonic, periphytonic and benthic organisms. Algae are unique model organisms in evolutionary biology and also are used in various genetic, physiological, biochemical, cytological, and other investigations.
