Most of the watercourses in the city of Presidente Prudente, state of São Paulo, Brazil, are channeled, and many others are inaccessible to the population. The city’s watercourses are degraded with silted beds, intense ...

Riparian forests are important for the structure and functioning of stream ecosystems, providing structural components such as large woody debris (LWD). Changes in these forests will cause modifications in the LWD input ...

We have studied single-channel conductance for different monovalent cations and streaming potentials caused by osmotic gradients of non-electrolytes in hemocyanin-treated membranes. We have found that the smaller ion, which ...

Human activities that modify land cover can alter the structure and biogeochemistry of small streams but these effects are poorly known over large regions of the humid tropics where rates of forest clearing are high. We ...

Peruvian auteur cinema has faced problems of distribution and cinematographic exhibition in the windows of massive scope. Most of the exhibition windows have been monopolized by big Hollywood productions. Currently, the ...

Habitat homogenization is one of the most important drivers of change in riverine fauna. Therefore, the aim of this study was to determine whether habitat homogenization influences the trophic structure of fish assemblages ...

The self-sustained turbulent shear or mixing layer that develops at the interface between a channel and a lateral cavity is the leading mechanism that drives the transfer of momentum and mass in these open-channel flows. ...

In lowland streams, channelization is a severe hydromorphological modification with negative impacts on ecosystem functioning and biological communities. We assessed the functional structure and spatial patterns of macrophyte ...

Benthic diatoms are often used for assessing environmental conditions, such as water quality and habitat conditions in stream and river systems. Although laboratory experiments have shown that each diatom species have ...
