This electron microscopy study of new for the Volgograd Region (Russia) Anomoeoneis sphaerophora f. sculpta, Gyrosigma wansbeckii, and Pleurosigma elongatum from mineralized tributaries (Bolshaya Samoroda, Lantsug and Khara) of the hyperhaline Lake Elton provides new data on the variability of quantitative diagnostic characteristics (valve length,...
The results of the analysis of data on rarely observed algal species on the territory of the Middle Volga Integrated Biosphere Reserve, based on the results of long-term observations are presented. In terms of frequency of occurrence, the number of singly recorded in general includes 286 species and intraspecific taxa, which is about a third of the...
This electron microscopy study of Achnanthes brevipes from mineralized tributaries (Solyanka, Chernavka, Khara) of the hyperhaline Lake Elton (Volgograd Region) provides new data on the variability of quantitative diagnostic characteristics (valve length, number of striae and areolae in 10 μm). Based on the original and published data, a refined di...
In this article the author presents some study results of taxonomic composition, distribution and migrations of algae under thermal stratification in small water bodies of the forest-steppe Volga region. The author considers the main factors influencing the formation of heterogeneity of the structure of algocoenoses: vertical temperature gradients,...
Saline rivers of Elton Lake Region (N49° 13', E46° 40') are highly productive systems. The flow of energy and nutrients can go beyond the hydroecosystem into the surrounding landscape, which is facilitated by the high diversity and quantitative development of the fauna. For the first time, field and experimental studies of planktonic and bottom com...
For the first time, an assessment was given of the taxonomic and quantitative structure of the phytobenthos of seven saline rivers in the basin of the hypersaline lake Elton (Volgograd Region). Main types of algacenoses developing on substrates were revealed, namely: diatom phytobenthos, communities of diatoms with cyanoprokaryotes, cyanobacterial...

... Algae proliferation can be restrained to a certain extent through timely observation, forecasting, and reservoir operation, but more aspects of management are needed to prevent algae blooms, such as controlling reservoir nutrient levels. Algae usually accumulates on the surface of reservoirs because of the abundant solar radiation and high nutrient concentration (Gorokhova, 2021). Therefore, more attention has been paid to the concentration of chlorophyll A on reservoir surfaces, and some scholars used surface water samples or satellite data to simulate chlorophyll A concentration (Cao et al., 2022;Chen et al., 2021;Woelmer et al., 2022). ...
... Водоросли планктона были изучены по характеристикам флористического и структурного разнообразия и количественным параметрам. К настоящему времени дана оценка таксономического, экологического, ценотического разнообразия, выявлены факторы его формирования в малых водоемах и водотоках СВБР [7,8,10,11,29]. Состав водорослей отдельных водоемов на Рис. 1. Схема мест нахождения исследованных водоемов уровне родов и видов имеет выраженные индивидуальные черты, что отражает экологическую специфику водного объекта. За десятилетний период в альгофлоре 23-х озер территории СВБР выявлено 909 видов и внутривидовых таксонов из 9 систематических отделов; в настоящее время список дополняется по результатам эпизодических исследований. ...
