Factors regulating trophic status in a large subtropical reservoir, China

Environmental Monitoring and Assessment, 2009
We evaluated a 4-year data set (July 2003 to June 2007) to assess the trophic state and its limiting factors of Three-Gorges Reservoir (TGR), China, a large subtropical reservoir. Based on Carlson-type trophic state index (TSI)(CHL), the trophic state of the system was oligotrophic (TSI(S) < 40) in most months after the reservoir became operational ...

Bacterial communities of four adjacent fresh lakes at different trophic status.

Ecotoxicology and Environmental Safety, 2018
Knowing the microbial compositions in fresh lakes is significant to explore the mechanisms of eutrophication and algal blooms. This study reported on the bacterial communities of the four adjacent fresh lakes at different trophic status by Illumina MiSeq

Anaerobic methane oxidation potential and bacteria in freshwater lakes: Seasonal changes and the influence of trophic status.

Systematic and Applied Microbiology, 2018
Nitrite-dependent anaerobic methane oxidation (n-damo), mainly carried out by n-damo bacteria, is an important pathway for mitigating methane emission from freshwater lakes.

Machine learning predictions of trophic status indicators and plankton dynamic in coastal lagoons

Ecological Indicators, 2018
Multivariate trophic indices provide an efficient way to assess and classify the eutrophication level and ecological status of a given water body, but their computation requires the availability of experimental information on many parameters, including ...

Estimation of the trophic status of selected Kazakhstan lakes

Russian Journal of General Chemistry, 2014
The trophic status of seven Kazakhstan lakes has been estimated basing on the data on total phosphorus content in the water. The estimated trophic status varies widely, from the oligotrophic-mesotrophic to the eutrophic-hypereutrophic ones.

Trophic status and trophic interactions of common predatory fish species of the West Kamchatka shelf

Journal of Ichthyology, 2015
Feeding and trophic relationships have been studied for the common benthic predatory fish species of the West Kamchatka shelf in 2008—the Pacific cod Gadus macrocephalus, great sculpin Myoxocephalus polyacanthocephalus, plain sculpin M. jaok, sea raven Hemitripterus villosus, and whitespotted greenling Hexagrammos stelleri. Crustaceans and fish are the

On the trophic status and conservation of Kashmir Lakes

Hydrobiologia, 1980
The lakes of the Kashmir Valley are generally shallow and situated in the flood plain of the river Jhelum. Thermal stratification is fairly uncommon, and stable stratification occurs in deeper lakes (12 metres, Manasbal lake). The waters are mostly low in dissolved solids, medium hard and slight to highly alkaline.
