Assessment of River Planform Dynamics in the Amazon Basin Using Sentinel-1 SAR Data (2017–2025)
Remote SensingThe Amazon Basin and its rivers play a vital role in regional biodiversity, the carbon cycle, and socio-economic security. Through erosion and deposition, river planforms change over time, affecting local infrastructure, food security, and changes to ...

A Museum-Curated, Voucher-Backed 12S Barcode Reference Library for Fishes of the Ecuadorian Amazon. [PDF]
Mol Ecol ResourABSTRACT Environmental DNA (eDNA) metabarcoding is an emerging method that promises to expedite and improve biodiversity surveys by identifying species from the genetic material they shed into the environment. eDNA methods offer many advantages over conventional specimen‐based surveys, but their effectiveness hinges on reference libraries, which for ...

Wildlife Letters, EarlyView.We used spatially explicit capture‐recapture to estimate jaguar densities in a private reserve in the Colombian Llanos and quantified land cover change in and around the reserve from 2014 to 2024. Densities increased 22% since 2014, while disturbed land cover increased by 39%–54% around the reserve depending on buffer distance. Our study indicates that

A big task for a miniature species: understanding Fluviphylax simplex (Cyprinodontiformes: Fluviphylacidae) distribution [PDF]
Neotropical IchthyologyThe different water types in the Amazon River basin are known to act as physico-chemical barrier to fish movement within the basin, especially to fish species adapted only to one water-type.

Evapotranspiration seasonality across the Amazon Basin [PDF]
Earth System Dynamics, 2017 Evapotranspiration (ET) of Amazon forests is a main driver of regional climate patterns and an important indicator of ecosystem functioning. Despite its importance, the seasonal variability of ET over Amazon forests, and its relationship with ...

Anthropic transformation in the Gurupi river basin, eastern Amazon
Sustentabilidade em Debate, 2019 The objective of this paper was to evaluate the degree of anthropic transformation of a river basin in the Amazon region. We used the digital data of the TerraClass Project to calculate the Anthropic Transformation Index - ATI. In order to verify spatial and temporal changes along a decade in the Gurupi river basin, we used the database of the years ...

Animal Conservation, EarlyView.We applied a multi‐scale, multi‐species framework to quantify how landscape structure and human infrastructure influence habitat use across a terrestrial mammal community within a biological corridor in the Colombian Amazon. Forest cover and spatial configuration influenced wildlife habitat use at spatial scales associated with species dispersal ...
