Overview of Limnology and Trophic Status
1984Figure 44 is a general synopsis of the annual cycle based on the foregoing chapters that have dealt with physical, chemical, and biological variables in Lake Dillon. The cycle is generalized for the 2 years of record. Layering and mixing patterns are the key to understanding chemical and biological changes through the year.

Isotopic signatures and trophic status of Ramaria
Mycological Progress, 2010The genus Ramaria is composed of several subgenera that often correspond to specific trophic strategies. Because carbon and nitrogen isotopes can be used to assess fungal trophic status and nitrogen sources, we accordingly carried out an extensive survey of isotopic patterns in archived specimens of Ramaria from Germany and other locations.

The trophic status of two Northern Irish sea loughs
Journal of Coastal Conservation, 1996Studies were conducted on nutrient cycling in two coastal embayments; Strangford Lough and Belfast Lough, in order to classify these coastal waters in compliance with the European Union Urban Waste Water Treatment and Nitrates Directives. Analysis of the data suggests that Strangford Lough is nitrogen-limited throughout much of the growing season with ...

The Trophic Status of the Bakhadda Dam Lake Using Physicochemical Analysis and Trophic Index
2021This work aims to deduce the state of surface water in the Bakhadda Dam according to rotifers and physicochemical parameters. The sampling was carried out monthly for 2 years from December 2015 to November 2017. Nineteen physical and chemical parameters were recorded.

Trophic status of fresh-water lakes in China
Russian Journal of General Chemistry, 2011In the article the trophic status of thirty one fresh-water lakes of China was described. Four lakes are characterized as mesotrophic, seventeen lakes have eutrotrophic status, and ten lakes are hypertrophic. Critical phosphorus loading for five biggest fresh-water lakes was calculated.

Pituitary Trophic Status as a Tumorigenic Determinant
2007Pituitary tumors are commonly encountered benign adenomas. Pituitary cell trophic status is an important determinant of pituitary adenoma development. Hormone secreting anterior pituitary cells exhibit slow turnover rates. Subsequent postnatal alterations in pituitary size are determined throughout the lifespan by both extrinsic and intrinsic factors ...

EVALUATING RESERVOIR TROPHIC STATUS: THE TVA APPROACH
Lake and Reservoir Management, 1984ABSTRACT TVA tributary and mainstem reservoirs show generalized differences in morphometry, hydraulics, nutrient loads, and response to nutrient conditions. Neither type of reservoir is comparable to the natural lakes on which classical eutrophication studies have been based.

Assessment of Trophic Status for Nansi Lake Using Trophic State Index and Phytoplankton Community
2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010The present study was to investigate the trophic state of Nansi Lake, a shallow lake employed in the South-to-North Water Diversion Project in China. Based on water transparency, total phosphorus (TP) and chlorophyll a (chl a) concentration, the modified method of Carlson's trophic state index (TSIM) was applied to assess the lake's trophic status. The

Factors regulating trophic status in a large subtropical reservoir, China
Environmental Monitoring and Assessment, 2009We 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 ...

Estimation of the trophic status of selected Kazakhstan lakes
Russian Journal of General Chemistry, 2014The 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.
