In the face of plans for increased construction of dams and reservoirs in the Mekong River Basin, it is critically important to better understand the primary-producer community of phytoplankton, especially the warm-water cyanobacteria. This is because these algae can serve as the primary source of carbon for higher trophic levels, including fishes, but can also form harmful blooms, threatening ...

More than 70,000 large dams have been built worldwide. With growing water stress and demand for energy, this number will continue to increase in the foreseeable future. Damming greatly modifies the ecological functioning of river systems. In particular, dam reservoirs sequester nutrient elements and, hence, reduce downstream transfer of nutrients to floodplains, lakes, wetlands, and coastal mar...

this time each year, we're asked if there are any advantages to placing Christmas trees or other types of brush piles in lakes for habitat enhancement. To answer that question, we've provided excerpts from an article written by Dr. Mike Allen, Associate Professor here at UF's Dept. of Fisheries and Aquatic Sciences. 1 Dr. Allen specializes in fisheries ecology and has produced numerous studies ...

In this study, otolith morphology and otolith contour from big-scale sand smelt, Atherina boyeri were analyzed in Lake Eğirdir and Lake İznik (natural lakes), and Hirfanlı Dam Lake (artificial lake). The otolith contour and sixteen otolith morphological characters such as width, depth, shape, sulcus acusticus shape, ostium, cauda, rostrum size-shape, and thickness, antirostrum size-shape, and t...

A paired whole-lake experiment was conducted on two remote, atmospherically driven lakes in the Experimental Lakes Area (ELA) to examine the stresses of trophic condition on air–water exchange and settling fluxes of polychlorinated biphenyls (PCBs). Lake 227 (L227) and Lake 110 (L110) are similar in volume, surface area, and watershed area but differ significantly in trophic status. The two lak...

The article reports the results of an experiment to assess geothermal potential territory based on measurements water reservoirs’ bottom temperatures.The research was conducted in 2021 Bolshoy Solovetsky Island, which, according some data, is characterized by presence anomaly one hand, and has a large number lakes other. For with depths greater than 5 m, temperature indicate that profiles corre...

Chemical composition of Arctic freshwater ecosystems depends on several factors. They include characteristics the surrounding landscape, its lithology, geomorphology, vegetation, and hydrological features, as well accumulation anthropogenic pollution. In Arctic, problem environmental contamination is widespread. That why research lakes river catchments in terms their chemical has enjoyed increa...
