Land cover change for agricultural expansion exerts strong pressures on tropical streams. We examined the relative contributions of catchment land cover, local environmental features, and spatial patterns on stream fish ...

The Tapajós river is among the largest rivers in the world and has been credited as the main affluent of the lower Amazon River. Geomorphological studies in the Tapajós commonly deal with evolutionary, hydrological, and ...

The conversion of forests into agriculture has been identified as a key process for stream homogenization. However, the effects of this conversion can be scale-dependent. In this context, our aim was to identify the influence ...

The aquatic macroinvertebrate community can be structured by processes in multiple spatial scales. Reduction or substitution of riparian forest by different land uses and the impacts on the physical and chemical conditions ...

We consider a family of two-dimensional nonlinear area-preserving mappings that generalize the Chirikov standard map and model a variety of periodically forced systems. The action variable diffuses in increments whose phase ...

The acquisition and the refinement of motor skills have been described to require a reciprocal relationship between organismic and environmental conditions. This interaction is evidenced in studies identifying the impact ...
