Zooplankton community and tributary effects in free-flowing section downstream a large tropical reservoir
(2016-04-01)
This study aimed to evaluate the zooplankton structures and environmental conditions in the interface reservoir-downstream river and tributaries. Zooplankton structure and environmental variables were analyzed in the ...
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 ...
Parámetros bióticos y abióticos en estanques de pesca subtropicales
(2014-01-01)
This study was conducted to evaluate the plankton communities and water quality at a fee-fishing farm over a 1-year period. Samples for the determination of biotic and abiotic variables were collected monthly during the ...
Spatial heterogeneity affecting fish fauna in cascade reservoirs of the Upper Parana Basin, Brazil
(Springer, 2014-10-01)
In cascade reservoirs, different zonation effects can be observed along the longitudinal axis, depending on the retention time of each reservoir. In this study, we evaluated the relationships among fish and spatial and ...
Trends in planktonic copepod diversity in reservoirs and lotic stretches in a large river basin in South America
(Csiro Publishing, 2014-01-01)
Copepod assemblages were analysed across La Plata River basin, the second largest in South America. High values of species richness and Shannon-Wiener diversity were found in the lower Parana River, the main and largest ...
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 ...
