How much inundation occurs in the Amazon River basin? [PDF]
Remote Sensing of Environment, 2021 The Amazon River basin harbors some of the world’s largest wetland complexes, which are of major importance for biodiversity, the water cycle and climate, and human activities. Accurate estimates of inundation extent and its variations across spatial and temporal scales are therefore fundamental to understand and manage the basin’s resources. More than

Amplified seasonal cycle in hydroclimate over the Amazon river basin and its plume region [PDF]
Nature Communications, 2020 The hydroclimatic variations of the Amazon River basin can exert profound impacts on the marine ecosystem in the Amazon plume region. Here the authors show that an amplified seasonal cycle of Amazonia precipitation during 1979–2018 leads to enhanced ...

Biodiversity underpins fisheries resilience to exploitation in the Amazon river basin. [PDF]
Proc Biol Sci, 2022 Inland fisheries feed greater than 150 million people globally, yet their status is rarely assessed due to their socio-ecological complexity and pervasive lack of data. Here, we leverage an unprecedented landings time series from the Amazon, Earth's largest river basin, together with theoretical food web models to examine (i) taxonomic and trait-based ...

Impacts of river fragmentation on limiting individual dietary specialization of Amazonian predatory fish [PDF]
PeerJ, 2022 Individual dietary specialization is one of the factors that promotes variation in resource use at the individual level. Here we used stable isotope analysis of multiple tissues with different turnover rates to examine the degree of individual ...

Home range and movements of Amazon river dolphins Inia geoffrensis in the Amazon and Orinoco river basins [PDF]
Endangered Species Research, 2021 Studying the variables that describe the spatial ecology of threatened species allows us to identify and prioritize areas that are critical for species conservation. To estimate the home range and core area of the Endangered (EN) Amazon river dolphinInia geoffrensis, 23 individuals (6♀, 17♂) were tagged during the rising water ...

An explicit GIS-based river basin framework for aquatic ecosystem conservation in the Amazon [PDF]
Earth System Science Data, 2016 Despite large-scale infrastructure development, deforestation, mining and petroleum exploration in the Amazon Basin, relatively little attention has been paid to the management scale required for the protection of wetlands, fisheries and other aspects of

Artisanal fisheries of the Xingu River basin in Brazilian Amazon [PDF]
Brazilian Journal of Biology, 2015 Abstract The present study characterises the commercial fisheries of the basin of the Xingu River, a major tributary of the Amazon River, between the towns of Gurupá (at the mouth of the Amazon) and São Félix do Xingu. Between April, 2012, and March, 2014, a total of 23,939 fishing trips were recorded, yielding a total production of 1,484 tons of fish,
