Flow and thermal regimes in river networks: effects of hydropower regulation and climate extremes
… conditions are the major factors in shaping water qualities in river networks, especially under the extreme climatic events. However, when the power of nature is encountered with human regulations, represented by hydropower production, it would be well worth discussing how the pictures of …

Variations in coral reef net community calcification and aragonite saturation state on local and global scales
… of any percent calcifier cover and short reef water residence time. NCC will also decline if percent calcifier cover declines, as evidenced by estimates of NCC in two Caribbean reefs having declined by an estimated 50-90% since 1880. The general NCC-Ωa relationship determined here, along with …

Supercritical water gasification of waste residues
… motor oil as a model compound, in supercritical water. Used motor oil was identified as a main waste compound leading to increased land fill concerns and supercritical water gasification is introduced as a method of decomposing such waste residues with high efficiencies. This study focused on …

Dissolved organic matter dynamics in diverse freshwater ecosystems across Canada: long-term trends, transformations, and explanatory factors
… organic matter (DOM) is a key variable in freshwater ecosystems that influences numerous limnological properties and ecosystem services. While DOM dynamics have received considerable attention in certain parts of Canada, many regions remain underexplored or require updated analysis. This …

Coal Combustion Residuals in Receiving Lake Ecosystems: Trophic Transfer, Toxicity, and Tracers
… the goals of these fields in the context of freshwater pollution by coal-fired power plant (CFPP) effluents, which contribute to the largest point source of environmental pollution in the United States and comprise a substantial threat to receiving ecosystems. CFPPs discharge the by-products of …

Bioaccumalation of metals in mullet from Mhlathuze Estuary and the effect of Cu and Pb on the uptake kinetics,haematology and acid-base balance of Liza dumerelii.
… included siltation of the estuary and loss of water residence time. The construction of the harbour was in line and enhanced the increase of industries in the Richards Bay area. The industries manufacture a number of metal products and also utilise other metal ores in the manufacturing process. …
