Primary productivity and chlorophyll a concentrations were measured in 8 reservoirs in New York City drinking-water-supply watersheds. The light-and-dark bottle O2-change procedure was used to measure gross primary productivity (GPP) once each summer from 2000 to 2002. GPP normalized for photosynthetically active radiation (PAR) in the Neversink and Schoharie averaged only 0.025 and 0.035 g O2/...

Spatial information of the dominant species of submerged aquatic vegetation (SAV) is essential for restoration projects in eutrophic lakes, especially eutrophic Taihu Lake, China. Mapping the distribution of SAV species is very challenging and difficult using only multispectral satellite remote sensing. In this study, we proposed an approach to map the distribution of seven dominant species of ...

Deep karst depressions with a large volume of water due to a poor water drainage system (caused by a clay layer, etc.) and with steeply sloping sidewalls paludificate in a special way. Peat formation begins with dead vegetative material (leaves, etc.) floating on the water's surface in the center of the karst lake. The peat grows laterally from the center of the depression to its edges and the ...

This study investigated the water quality in an urban eutrophic reservoir in Northeastern Brazil, considering the influence of seasonality. Monthly, samples were collected in the sub-surface reservoir. The following abiotic variables were analyzed: temperature, pH, dissolved oxygen, apparent color, turbidity, conductivity, fluoride, total nitrogen, chlorides, total dissolved solids, total hardn...

Lake water has been impaired with nutrients due to the synergic action of human-made activities and climate change. This situation is increasing eutrophication around globe faster than before, causing degradation, loss its uses, water-associated economic health effects. Following Sustainable Development Goal 6, more precisely target 6.6, nations are already behind schedule in protecting restori...

Microcystis aeruginosa is a major primary producer and a common toxic cyanobacterium, playing an important role in the aquatic environment (Chen et al., 2016). Microcystis aeruginosa is commonly observed in highly eutrophic lakes (Watanabe and Oishi, 1985). In recent years, surface cyanobacterial bloom occurred frequently in most large shallow lakes in China, such as Lake Taihu (Zhang et al., 2...

Bromeliads tank water or phytotelma is an eutrophic microenvironment where microorganisms have evolved to resist sudden changes in pH and nutritional competition. Metagenomics studies have been poorly studied in bromeliads and environmental DNA (eDNA) characterization for its microenvironment is deficient in Puerto Rico. Therefore, the data represents the microbial communities inhabiting bromel...

I measured physico-chemical properties and phytoplankton in the small, shallow tropical reservoir of Oyun (Offa, Nigeria) between January 2002 and December 2003. I identified 25 phytoplankton genera in three sampling stations. Bacillariophyceae dominated (75.3%), followed by Chlorophyceae (12.2%), Cyanobacteria (11.1%) and Desmidiaceae (0.73%). The high amount of nutrients (e.g. nitrate, phosph...
