Wetlands are among the most productive ecosystems globally characterized by dynamic
interactions between terrestrial and aquatic habitats at different scales. These systems …

The long‐term impacts of large hydroelectric dams on small‐scale fisheries in tropical rivers
are poorly known. A promising way to investigate such impacts is to compare and integrate …

The São Francisco River was first encountered by Europeans on the 4th of October, 1501-
Saint Francis' Day-by Américo Vespúcio and Gaspar Lemos, hence the river's current name …

Resource assessments of small-scale fisheries in the Amazon are rare, making it difficult to
improve fisheries management. This study assessed the sustainability of small-scale fishery …

Rural populations in the tropics frequently rely on game vertebrates and fish to supply their
daily protein requirements. However, few studies have quantified the environmental and …

Background: Subsistence ribeirinhos of the Amazon Basin depend on fish for their principal
source of protein, but fish availability changes with seasonal high and low waters. Aim: To …

Tropical fisheries, which are considered multi-species, may show selectiveness. We
analyzed the degree of selectivity of fish catches in 46 sites along the Amazon basin through …

Biological invasions and damming are currently considered the main threats to aquatic
biota. This is aggravated by the facilitative effect of damming on dispersal and establishment …

Flooded forest is one of the most important fish habitats in Neotropical rivers, and one that is
increasingly subjected to negative impacts from logging, agriculture, and other human …

Previous work has indicated, at least in two river systems, that some Characiformes species
migrate from nutrient‐poor rivers to spawn in nutrient‐rich rivers. In the present work, larval …
