Addressing the trophic status in urban ponds: An evaluation of current trophic state indexes

Austral Ecology, 2023
AbstractPonds are generally understudied. Quality problems in urban freshwaters can arise from eutrophication, and trophic status classification gives information related to their ecological situation. Ponds may strongly differ from larger lakes for which most current trophic status classification methods have been developed.

Trophic Status of Peipus Lake

Russian Journal of General Chemistry, 2017
The data of hydrochemical and hydrobiological monitoring of the Estonian water area of Lake Peipsi (Peipus, Chudskoe) during 1985–2016 are presented. The trophic state of the water area has been determined according to different methods. According to the method developed at the Hydrochemical Institute, the trophic state of the Estonian waters of Lake ...

Overview of Limnology and Trophic Status

1984
Figure 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.

The Trophic Status of the Bakhadda Dam Lake Using Physicochemical Analysis and Trophic Index

2021
This 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.

Isotopic signatures and trophic status of Ramaria

Mycological Progress, 2010
The 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.

Monitoring the trophic status of reservoirs

2021
The current situation of regional, rather' than national, problems of eutrophication in standing waters has been widely aired in recent reports. A reliable, quantitative data base is a prerequisite to future trend monitoring, a concensus view of those reports. The objective of this report is to establish requirements, methodology and a minimal data set

The trophic status of two Northern Irish sea loughs

Journal of Coastal Conservation, 1996
Studies 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 ...

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.

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.
