“…The WESI index makes it possible to assess the general level of toxic effects on the autotrophic organisms of aquatic ecosystems [42]. Earlier, this index was successfully applied to assess the total level of toxic pollution of water bodies in various regions [59][60][61][62][63][64]. According to WESI values, the mountainous part of the Arys River basin was characterized by a low level of toxic pollution (Figure 7).…”

Assessment of the water quality of the Arys River basin based on the spatial distribution of richness of phytoperiphyton communities and abiotic variables was given for the first time. Altogether, 82 species were revealed in phytoperiphyton, including Bacillariophyta of 51, Cyanobacteria of 20, Chlorophyta of 7, and Charophyta of 4. Cluster analysis revealed the uniqueness of the composition of periphyton communities related to the abiotic conditions. The environmental preferences of the algae indicated fresh organic pollution in the lower reaches of the Arys River and weak or moderate levels of organic pollution in the rest of the basin. The ecological mapping of chemical data generally confirmed this conclusion. According to the maps, the highest water quality was revealed in the upper stream of the basin. The middle part of the river basin had the lowest water quality in terms of transparency, nitrite-nitrogen, and nitrate-nitrogen. The downstream of the Arys was characterized by a secondary deterioration in water quality according to the Aquatic Ecosystem State Index (WESI) index. We revealed the complicated interaction between natural and anthropogenic factors that caused changes in water quality in the Arys River basin.

“…The species richness of phytoplankton communities was clearly traced in the salt gradient for water bodies in some regions (Barinova et al, 2009(Barinova et al, , 2011(Barinova et al, , 2015Klymiuk et al, 2014;Bilous et al, 2016). The non-parametric correlation analysis results and 3d Surface Plots revealed a more complex character of the relationship of species richness of algae with hydrochemical conditions in lake Balkhash.…”

The spatial distribution of species richness of phytoplankton was studied along the Balkhash Lake water area during the summer of 2004. With statistically weak connections of phytoplankton with environmental parameters, three-dimensional graphs revealed a complex character of its spatial variability in the gradient of environmental factors. Macrophytes had a stimulating effect on the species richness of planktonic algae. We found a correlation between species richness of Cyanobacteria, Chrysophyta, Euglenophyta and Dinophyta and the ionic composition of water. The important role of temperature was traced. Species richness of algal communities increased with increasing temperature in the gradient of nutrients and correlated with the abundance of macrophytes.

“…Подобная реакция водорослевых сообществ отмечена C. С. Бариновой и др. [16]. Очевидно, такая реакция способствует их большей устойчивости к возрастающему экологическому прессу в высоких широтах.…”

“…Путем последовательного применения ряда методов многомерной статистики в настоящем и предыдущих исследованиях [2−4] определены и другие важные переменные (температура воздуха, индекс динамики местообитаний DHI, продолжительность периода отсутствия льда на реках), совокупность которых указывает, что лимитирование развития высокоширотных водорослевых сообществ происходит за счет короткого вегетационного периода. Некоторые исследователи [16] пришли к выводу, что короткая продолжительность безледного периода на арктических реках лимитирует доступ солнечной радиации для фотосинтезирующих организмов. Это неверно, так как в зимний период большая часть арктических рек промерзает до дна, функ-ционирование планктонных сообществ в этот период прекращается.…”

On the basis of data-array analysis (2000–2011) of phytoplankton in large subarctic rivers; the rivers’ hydrochemical, hydrological, and morphological parameters; and climatic properties of the catchment-basin areas and by using stepwise discriminant analysis and clustering, it was determined that formation of phytoplankton spatial structure is mostly affected by climate rather than by physical-chemical properties of the river waters in northeastern Siberia. Floristic structure of phytoplankton is mostly connected to abiotic factors among phytoplankton-development indicators. The duration of vegetation-growth period is another important environmental factor.
