TL;DR: In this article, the authors combined fish and environmental data collected in situ and satellite-mapped landscape features to evaluate how fish species with different ecological strategies and assemblage structures respond to deforestation in floodplains of the Amazon River.

TL;DR: Fish is the most important source of animal protein for this region, with an annual mean consumption rate of 550 g capita−1 day−1, and the fishery has changed from a subsistence to a commercial scale, which was associated with increasing cattle ranching activities.

TL;DR: In this article, the authors examined the evidence for metapopulation structure in the Amazon River Basin and found that the most promising conservation strategies involve: (1) reduction in dam building; (2) establishment of large enough protected areas to incorporate high β diversity and maintain patterns of connectivity during anomalous low water events; (3) implementation of governmentally facilitated community-based fishing agreements to curb overexploitation and monitor sustainable population levels and connectivity in protected areas.

TL;DR: A complexidade da pesca amazonica e muito alta can be found in this paper, where a revisao das modalidades of pescas that ocorrem in the biação amazonicas is presented, relatando os principais recursos explotados in cada uma delas e uma analise preliminar do estado de sustentabilidade do pro c e s s s o de explotacao.

TL;DR: In this paper, the authors argue that the environmental impacts of this project are likely to be large, and will result in substantial loss of biodiversity, as well as changes in the flows of ecological services.
