“…Our results showed that Bacillariophyceae and Chlorophyceae were the main successful algal groups, contributing to more than 80% of TSR. This pattern is consistent with those for the lower reaches of the Pearl River (Wang et al, 2014, 2016) and in other large global rivers (Belous & Klochenko, 2015; Bilous, Lilitskaya, & Kryvenda, 2015; Dokulil & Donabaum, 2014; Piirsoo, 2001). A. granulata was the most dominant species in the phytoplankton community of the East River, potentially due to several reasons.…”

Since the serial discontinuity concept (SDC) of rivers is proposed, few studies have tested it in a highly fragmented river ecosystem. In this study, environmental factors, phytoplankton species richness, and SDC predictions were demonstrated along the 13 cascade dams in a subtropical river (China). Our results indicated that among environmental factors, water temperature and transparency have seasonal differences, and river width has spatial differences; total species richness (TSR) increases from upstream to downstream, and distance is the reason for its variation. In addition, TSR also has spatial variations in each cascade dam, with the maximum or minimum value of each cascade section often occurring near the dam. A predictive model was constructed and revealed that seasonal differences in species richness were more significant than spatial differences, which were mainly observed during wet periods. Taken together, these results suggest that the construction of cascading dams enhances spatial differences in phytoplankton species richness, especially during periods of abundant water. In addition, environmental parameters such as water temperature, pH, and DO and TSR all support SDC predictions. In the future, we will continue to investigate this aquatic ecosystem to study more phytoplankton-related indices affected by the cascade damming, and hope to fully validate the SDC predictions.

“…communis (E. Hegewald) E. Hegewald, Desmodesmus opoliensis (P. G. Richter) E. Hegewald, Micractinium pusillum Fresenius, Scenedesmus acuminatus (Lagerheim) Chodat. Chlorophyta were the same prevailing group of algae mentioned for this area in recent studies (Belous, 2014;Belous et al, 2013;Belous & Klochenko, 2015;Bilous et al, 2014) In addition, high values of phytoplankton abundance (mainly for Site 5) were found in both periods. One possible reason for high phytoplankton abundance could be nutrient and organic matter input originating from sugar beet cultivation, alcohol, and sugar industry in the region (Uladivka village).…”

“…As highlighted in Radzymovsky (1933), 63 riverine ponds were located in 3 tributaries (Snyvoda, Rov, and Sob) in this section, as the high regulation of the river has been proven to have an impact on the same parameters of the phytoplankton in recent studies (Belous, 2014; Bilous et al, 2014). The taxonomic richness of phytoplankton for the upper and middle parts of the Southern Bug River during the current period also tends to have high values (the highest values of taxa ranged from 111 up to 134, (Belous & Klochenko, 2015; Bilous et al, 2012; Bilous et al, 2014). The increase of a number of taxa could be assumed to be connected with a higher number of studied sites and higher heterogeneity in habitat conditions among them as well as some scientific progress in methodology for species identification nowadays.…”

The phytoplankton functional group (FG) classification system sensu Reynolds enables evaluating the ecological status of rivers using the Q(r) compositional index. Here, we apply the Q(r) index to analyze the ecological conditions of the Southern Bug River, at the entire river length, in the early 20th century, testing it first on historic river phytoplankton data. Moreover, we combined the FG approach with the saprobic index and taxonomic richness to assess the ecological status of the river more reliably. The Bray–Curtis Similarity index highlighted the spatial clustering of river sites that corresponded well to the bioregions of the Eastern Lowlands and the Pontian Province. The Q(r) index revealed a higher variation in ecological status among sites than the saprobic index. Therefore, we argue that the FG approach provides a sensitive ecological status indication approach for river phytoplankton, including historical human impacts. The method may improve understanding of reference conditions and assessing the ecological status of Ukrainian rivers, as requested by the European Water Framework Directive.
