Energy flow and network analysis of Terminos Lagoon, SW Gulf of Mexico
(Journal of Fish Biology, 1998)
The food web in Terminos Lagoon, south-western Gulf of Mexico was dominated by the detrital pathway, with benthic invertebrates playing a significant role in transferring energy from detritus to higher trophic levels. The ...
An index for defaunation

Assessment of the efficiency of a trophic state index in determining the water quality of public water supply reservoirs
(Assoc Brasileira Engenharia Sanitaria Ambiental, 2018-07-01)
The aim of this study consists in the evaluation of the trophic state index (IET) efficacy as a tool in the water quality analysis of three reservoirs. The IET was calculated based on water transparency in the reservoir ...
Trophic State Evolution over 15 Years in a Tropical Reservoir with Low Nitrogen Concentrations and Cyanobacteria Predominance
(2016-03-01)
Anthropic eutrophication is one of the most widespread problems affecting water quality worldwide. This condition is caused by excessive nutrient inputs to aquatic systems, and one of the main consequences is accelerated ...
Estimating fish production in the itaipu reservoir (Brazil): The relationship between fish trophic guilds, limnology, and application of morphoedaphic index
(2014-10-01)
Many experimental studies contributed to the development of the theory of the lacustrine food web, disclosing the important paper of the fish, for decades ignored by the limnology. This work is based on the hypothesis of ...

Efeito da remoção da vegetação ripária sobre a rede trófica de uma assembleia de peixes de um riacho neotropical
(2018-01-01)
The study of the diet of fish is an important tool to assess different levels of environmental degradation, since the availability of food in the environment is a key factor for the fish occurrence. The removal of riparian ...
