“…The bioindication method is integral and allows one to determine the dynamic of ecosystem development under the influence of the sum of factors, and not only to quantitatively determine a given physical or chemical parameter at the time of sampling [39,40,42,[51][52][53][54]. In addition, the use of bioindicators can help in cases where chemical analysis data are not available [55], as in our case when a small set of chemical data was published for a historical period [2,47,48].…”

“…This is a fairly large list of species for such a small territory and was sporadically studied compared to other wetlands in Europe, Israel, Ukraine, and Kazakhstan [50][51][52][53][54]. The same problem with the unevenness of research was successfully solved in the study of long-term changes in the lake using a list of algae and cyanobacteria species from publications of previous years [55] on the territory of Ukraine.…”

Lake Hula, the core of one of the most extensive wetland complexes in the Eastern Mediterranean, was drained in 1951–1958. However, about 350 hectares of papyrus marshes were allocated in the southwestern part of the previous lake and became the Hula Nature Reserve status, the first of two wetlands in Israel included in the Ramsar List of Wetlands of International Importance. The list of algae and cyanobacteria species of Lake Hula was compiled by us for the first time based on data from publications of 1938–1958, as well as our research in the Hula Nature Reserve, obtained within the framework of the monitoring program for 2007–2013. The list includes 225 species and intraspecies of algae and cyanobacteria belonging to eight phyla. The dynamics of the species richness of algae and cyanobacteria flora for 1938–2013 are shown. Species-bioindicators of water quality have been identified, and the change in their composition by ecological groups for a period of about a hundred years has been shown. Based on the species richness of algae communities, water quality indices were calculated with particular attention to changes in trophic status during the study period. The algae flora of Lake Hula and Hula Nature Reserve was found to be similar, but bioindication has revealed an increase in salinity and organic pollution in recent years.

“…To determine the environmental factors affecting the diversity of phytoplankton in the Sasyk, a few studies were performed. Bioindicator analyses were performed according to [22], based on species-specific ecological preferences of the revealed algae and cyanobacteria [23][24][25], with the combination of species with similar ecological properties to indicator groups reflecting the response of aquatic ecosystems to habitat, pH, oxygenation, water mass dynamics, salinity, trophic state, and the class of organic pollution. The analysis of bioindicators included several steps.…”

Forty years ago, the transformation of the estuary of the Black Sea to a freshwater reservoir was started by its connection with the Danube River through the Danube–Sasyk Canal. Today, the inflow of the Danube water into the Sasyk is the main component of the water balance, affecting the internal and external water exchange, and it is, in general, responsible for the quality of the aquatic environment. In addition, the channel is a migration route for hydrobionts and the main source of invasion. We describe the changes in the composition of algal communities in Sasyk, which was converted from an estuary to a reservoir during three stages: estuary-lake in 1967–1977 (stage I), the forming of the reservoir from 1980–1990 (stage II), and the reservoir from 2013–2019 (stage III). Average salinity decreased from 7790 to 491 mg L−1 chlorides, and the species richness of algae increased from 259 to 289 taxa during the Sasyk transformation. Analysis of the algal communities revealed that salinity could have an effect on their composition. The species list for the Sasyk, including 586 taxa of algae and cyanobacteria (613 infraspecific taxa), is presented here for the first time. Rare marine and freshwater taxa present in the algal community at the modern stage of the reservoir and their transformation are discussed. An ecological analysis of the different stages of the Sasyk transformation from an estuary into a reservoir was conducted. The increase in species richness for stages II and III along with an increase in desalination was noted. To keep the current ecological status of the reservoir and its hydrological stability, the role of the Danube River should be considered. Bioindicators, statistical analysis of species, and environmental variables’ relationships confirm salinity as a major regulating factor that can be observed by way of long-term monitoring.

“…[56]. Considering identified indicator groups, the intervals of the water quality classes calculated on the basis of organic pollution by Sládeček are distributed as follows: I (high class of water quality)-0-0.5 (xenosaprobionts, xeno-oligosaprobionts), II (good)-0.6-1.5 (oligo-xenosaprobionts, xeno-beta-mesosaprobionts, oligosaprobionts, oligo-beta-mesosaprobionts), III (moderate)-(beta-oligosaprobionts, oligo-alpha-mesosaprobionts, beta-mesosaprobionts, beta-alpha-mesosaprobionts) and IV (bad)-(alpha-mesosaprobionts) [17,20,55,57,58].…”

The river basin of Siversky Donets is of great scientific interest since this river runs through a territory with heavy industry (in particular, coal mining, chemical processing and metal industries). Within the basin, rivers of different sizes were explored (small, medium, large and extra-large) that flow through siliceous and calcareous rocks on the same elevation (lowland—below 200 m a.s.l.). Phytoplankton, as one of the Biological Quality Element, was used to perform the assessment of ecological status of the water bodies within the Siversky Donets river basin in 2019. The state monitoring program based on the updated approaches has been implemented in the river basin for the first time. The composition of phytoplankton species in the basin comprised 167 species (168 intraspecies taxa), mainly Bacillariophyta (63%) and Chlorophyta (22%) with the presence of other species (Cyanobacteria, Charophyta, Chrysophyta, Dinophyta and Euglenophyta). High species diversity and divisions amount are a distinctive property of the smaller rivers, while the bigger rivers show lower number of divisions. The “bloom” events, which are important ecological factors, were not detected in the Siversky Donets river basin. Algal species composition in plankton samples of the basin was identified and series of ecological parameters, such as habitat preferences, temperature, pH, salinity, oxygenation and organic water pollution according to Watanabe and Sládeček’s index of saprobity (S) trophic state and nitrogen uptake metabolism were analyzed. The ecological conclusions were also verified by a canonical correspondence analysis (CCA). The significance of the Canonical Correspondence Analysis (CCA) results was estimated of by a Monte-Carlo permutation test. The high concentrations of inorganic phosphorus compounds (permanganate index (CODMn)) and nitrite ions favored the diversity of Chlorophyta and Cyanobacteria diversity correlated with the levels of bicarbonate and CODMn. High diversity of diatoms was facilitated by the total amount of dissolved solids and chemical oxygen demand (COD). It was found that low water quality could be associated with conditions leading to predominant growth of the mentioned groups of algae. According to the analysis, the highest water quality was characterized by balanced phytoplankton composition and optimal values of the environmental variables. The sites with reference conditions are proposed for future monitoring.
