Trophic opportunism of central Amazon floodplain fish [PDF]
SummaryThe food web of the central Amazon basin displays one of the largest discrepancies in food source utilisation versus availability for consumers. While C4macrophytes dominate the primary producing biomass in floodplains, the food web is dominated by the use of C3carbon sources.

Climate change is projected to substantially erode taxonomic, phylogenetic, and functional diversity of endemic and threatened birds in the Brazilian Amazon by 2100. Integrating these dimensions with climate refugia revealed priority conservation areas, particularly in the eastern Amazon, highlighting where conservation efforts can best safeguard ...

Annual net primary production of macrophytes in the eastern Amazon floodplain
Aquatic herbaceous macrophytes contribute significantly to the input carbon for the Amazon floodplain. These plants have large seasonal variations in areal coverage and high productivity. The present study estimates annual net primary production (NPP) of

ABSTRACT Hydroelectric dams are common in Amazonian tributaries under federal environmental licensing that requires long‐term fisheries monitoring. This study evaluated three fishing systems targeting “pacu” species (Serrasalmidae) in the Xingu River before, during, and after construction of the Belo Monte dam (2012–2023) across four river sectors ...

Shape of Water: Power Dynamics for Supply Chain Resilience
ABSTRACT The world is facing climate change‐driven disruptions such as extreme weather events, which affect nature as well as firms and their supply chains. Nonetheless, little is known about how supply chain players shape their socioecological resilience, including from a power perspective.

ABSTRACT Research on strategic alliances often treats supplier capability development as an outcome, but rarely asks which capabilities are built or what they can be used for. We address this through an embedded single‐case study of a lead‐firm‐orchestrated network in the Brazilian Amazon, comprising six community‐based enterprises (CBEs) supplying ...

Abstract Introduction The restoration of mining‐degraded riparian forests faces challenges due to structural, compositional, and functional impacts on these ecosystems. The demand for effective monitoring requires an understanding of how ecological indicators have been applied to assess post‐mining restoration success.

Assessment of two biomass estimation methods for aquatic vegetation growing on the Amazon Floodplain
Studies of macrophyte productivity in the Amazon region are limited by accessibility and costs; hence, they may suffer from reduced sample size and representation.

Chemical features of floodplain soils under different land-uses in the Solimões/Amazon River basin
Most studies regarding the impacts of agricultural systems on soils of the Amazon region of Brazil have been carried out on upland soil, locally known as terra firme.
