Dissolved oxygen is an influential factor of aquatic ecosystem health. Future predictions of oxygen deficits are paramount for maintaining water quality. Oxygen demands depend greatly on a waterbody’s attributes. A large sediment–water interface relative to volume means sediment oxygen demand has greater influence in shallow systems. In shallow, ice-covered waterbodies the potential for winter ...

Harmful algal blooms are increasingly common in aquatic ecosystems and have been linked to runoff from agricultural land. This study investigated the internal nutrient (i.e., phosphorus (P) and nitrogen (N)) dynamics of a eutrophic reservoir in the Midwestern United States to constrain the potential for sedimentary nutrients to stimulate harmful algal blooms. The spatial distribution of nutrien...

Blooms of Microcystis aeruginosa occurred in summer months for several years in the reservoir of Grangent (France). Disappearance of planktonic colonies in autumn does not necessarily mean the end of the life cycle for cyanobacteria, and part of them sink down to the sediment. Frequency of dividing cells (FDC) of benthic M. aeruginosa was measured under experimental hypolimnetic conditions in w...

Cycling of water quality constituents in lakes is affected by thermal stratification and homo-thermal conditions other factors such as oligotrophication, eutrophication, microbial activities. In addition, hydrological variability can cause greater differences residence time cycling man-made (reservoirs) than natural lakes. Thus, investigations are needed on vertical mixing new impounded reservo...

Oxygen plays a crucial role in aquatic ecosystem particularly for supporting aquaculture and hydropower. In freshwater, importance of oxygen is metabolic respiration balance heterotrophic organisms. also involved various chemical equations which compounds influence each other. To prevent depletion, understanding the changes DO all interactions with other water qualities been reviewed purposed t...

The present study aimed to elucidate relationships between phytoplankton species and stressors using multivariate approaches assess the environmental condition of Burç Reservoir?s surface water metrics from September 2018 August 2019 according implementations Water Framework Directive. Reservoir had a characteristic warm monomictic pattern. Phytoplankton functional groups (E, F, J, LO, LM, MP ,...
