Ciência e Natura, 2020 The Chironomidae larvae are sensitive to variations in aquatic ecosystem conditions. We aim to analyze the variation of Chironomidae trophic guilds and their relation to the trophic state index in reservoirs in the semiarid. The study was conducted from 66 sites, distributed in the littoral zone of three reservoirs of Piranhas-Assu river, during June ...

Towards Methodological Problems of Trophic State Assessment of Running Waters
, 2015 Deep analysis of trophic state assessment methods has led to conclusion, that currently there is no universal methodology and existing methods are characterized by significant shortcomings. The approach proposed by the authors is different from generally

Determination of the Trophic State of Lake Uluabat (Bursa-Turkey)
Ekoloji, 2015 Eutrophication has become a widespread matter of concern during the last 50 years. Because of the relationship between biotic and abiotic factors, the determination of the trophic level of lakes is important. In this study, the trophic level of Lake Uluabat was determined using different trophic states indices (TSISD, TSICHL, TSITP, and TSITN) in 8 ...

A trophic model of the coastal fisheries ecosystem off the west coast of Sabah and Sarawak, Malaysia [PDF]
A mass-balance steady-state trophic model of the coastal fisheries ecosystem off the West Coasts of Sabah and Sarawak, Malaysia (10 - 60 m depth) was constructed using the Ecopath software. The ecosystem models were partitioned into 29 ecological/trophic

Trophic model of the coastal fisheries ecosystem of the southwest coast of India [PDF]
The Ecopath approach and software were used to construct a trophic model of the coastal fisheries ecosystem of the southwest (SW) coast of India. The model consisted of 11 ecological groups and used estimated landings from all areas along the southwest ...

Zooplankton and Trophic State Relationships in Florida Lakes
, 1983 Zooplankton, including ciliated protozoans, were collected from 39 Florida lakes of widely ranging trophic state. Annual mean biomass values for different zooplankton groups were regressed against Carlson's Trophic State Index based on annual mean ...
