The study aimed to investigate the physico-chemical properties as well phytoplankton and bacterial community diversity of Bovan Lake reservoir in Serbia gain insight into seasonal dynamic water quality. All analyses were performed at three localities depths spring, summer, autumn, winter 2019. Seven phyla comprising 139 taxa detected all (Chlorophyta 58%, Bacillariophyta 14%, Cyanobacteria 9%, Chrysophyta 5%, Dinophyta Euglenophyta Cryptophyta 4%). Winter 2019 was characterized by presence 36 unique species except Euglenophyta. Bacterial showed that Proteobacteria, Actinobacteria, Bacteroidetes, Cyanobacteria, Verrucomicrobia dominated intake locality (0.5, 10, 20 m below surface). In general, parameters, phytoplankton, composition depended on season depth satisfactory ecological status quality localities, meets needs for intended purposes.

The factors related to cyanotoxin occurrence and its social impact, with comprehension risk perception being the most important issues, are not yet completely understood in Cuban context. objectives of this research were determine extension microcystin-LR levels, identify environmental that trigger toxic cyanobacteria growth 24 water reservoirs eastern Cuba. Samplings performed early morning hours, situ determination physicochemical analysis carried out laboratory. Microcystin-LR determined within cells (intracellular toxins) using UPLC–MS after solid phase extraction. studied found be affected by eutrophication, high levels TN:TP ratio phytoplankton cell concentrations, temperatures low transparency, which cause collateral effect such as cyanobacterial bloom occurrence. In Hatillo, Chalóns, Parada, Mícara, Baraguá, Cautillo, La Yaya, Guisa Jaibo reservoirs, concentrations MC-LR higher than WHO limits for drinking (1 µg·L−1), detected.

Abstract The present analysis shows that the most crucial parameter for a correct representation of observed temperature behavior are heat exchange coefficient and wind. different approaches tested all have limitations, but they can reproduce reservoir trends at depths with maximum standard deviation ranging from 3 °C to 8 °C.

Abstract Tragic incidents involving mine tailings spills have impacted many aquatic ecosystems around the world. The massive dam collapse of Fundão, which occurred in Brazil 2015, affected several ecosystems, including shallow and deep lakes lower Doce River basin. Until now, effects on functional diversity zooplankton remain poorly understood. We investigated (functional groups, richness [FRic] evenness [FEve]) lakes, exploring influence environmental variables metals. In addition, trends redundancy vulnerability were also assessed to understand patterns resilience mining‐impacted ecosystems. Surveys performed monthly three by failure, from October 2018 September 2019. community was dominated smaller filter‐feeders omnivorous species, associated with cyanobacteria density chlorophyll‐ a . Medium‐sized filters iron, suspended particulate organic matter total carbon lakes. trophic groups had higher contribution increasing than medium‐sized both FRic FEve Shallow highly vulnerable species loss modulated changes metal pollution. Tropical mining should receive particular attention conservation plans, as consequence their high level pollutant retention comparison we highlight importance using approach better ecosystem resulting impacts environments.
