摘要
库伦达草原钠湖是俄罗斯唯一出现的高盐钠湖。它们的特点是具有温度和盐水浓度周期性高振幅波动的可变水文状态。1927-1932年,以N.N. Voronikhin为首的苏联心理学家首次对库伦达草原湖泊的藻类进行了研究,并描述了新的分类群:Lochmiopsis Woronich藻类属。et Popova(后修订为Ctenocladus circinnatus Borzì)和蓝藻种Aphanocapsa salina Woronich。;棘球藻;,假变异毛霉(Anabaena)Komárek et Anagnostidis, Anabaenopsis issatschenkoi Woronich。,米氏虾青藻。纳氏虾青藻;,偏曲振荡菌变种;、Limnospira(节螺旋藻)、fususiformis (Woronich.)Komárek et Lund。后来(自2007年以来),来自Winogradsky研究所的微生物学家继续进行研究。本文对库伦达草原苏打湖1929-1932年和2007-2020年的藻类多样性进行了比较,并对所选真核藻类和蓝藻的分类问题进行了简要概述。总共鉴定出33种蓝藻形态。大多数种类的藻类和蓝藻被描述基于专门的形态学标准。因此,它们的系统发育位置仍然不清楚,需要使用现代多相方法进行仔细分析。
Phototrophic communities of Kulunda Steppe soda lakes (Altai Region): history of algological studies and modern data.
The Kulunda Steppe soda lakes are the only occurrence of hypersaline soda lakes in Russia. They are characterized by a variable hydrological regime with cyclic high-amplitude fluctuations of temperature and brine concentration. The algae of the Kulunda Steppe soda lakes were first studied by Soviet phycologists headed by N.N. Voronikhin in 1927–1932 and new taxa were described: algal genus Lochmiopsis Woronich. et Popova (later revised to Ctenocladus circinnatus Borzì) and cyanobacterial species Aphanocapsa salina Woronich., Synechocystis crassa Woronich., Trichormus (Anabaena) pseudovariabilis (Woronich.) Komárek et Anagnostidis, Anabaenopsis issatschenkoi Woronich., Anabaenopsis milleri Woronich., Anabaenopsis nadsonii Woronich., Oscillatoria deflexa var. crassa Woronich., Limnospira (Arthrospira, Spirulina) fusiformis (Woronich.) Komárek et Lund. Later (since 2007) studies were continued by the microbiologists from the Winogradsky Institute of Microbiology RAS. In this work, a comparison of the algological diversity found in the soda lakes of the Kulunda Steppe during periods 1929–1932 and 2007–2020 is made, and a brief overview of taxonomic problems of selected eukaryotic algae and cyanobacteria is given. In total, 33 morphotypes of cyanobacteria were identified. Most species of algae and cyanobacteria were described based on the exclusively morphological criteria. Thus, their phylogenetic position remains unclear and requires careful analysis using a modern polyphasic approach.
