Coagulant application and the removal of bentivorous fish are two techniques of water quality management of eutrophic lakes, which decrease or increase the internal phosphorus of sediments to a water column and mitigate ...

Planktivorous and benthivorous fish may promote the increase of phytoplankton biomass and turbidity by suppression of zooplankton, resuspension of sediment and recycling or translocation of nutrients. These effects are ...

The reduction in the volume of lakes and reservoirs due to increased water deficit during periods of drought should affect the structure and trophic dynamics of these ecosystems, increasing the density of organisms, the ...

The food chain theory predict that presence of omnivory prevent the trophic cascade and could be a strong stabilizing factor over resource and consumer community dynamics, and that the nutrient enrichment destabilize ...

The artifi cial eutrophication is one of the biggest t h reat for the quality of aquatic ecosystems in the whole world. The expectations for the future climatic scenarios in arid and semi - arid ...

Omnivory is a predominant feeding strategy among tropical fishes, but knowledge about its causes and consequences of this pattern is scarce. In this study we hypothesized that tropical fish feed lower in food web as a way ...
