Determining a Threshold to Delimit the Amazonian Forests from the Tree Canopy Cover 2000 GFC Data [PDF]
Sensors, 2019 Open global forest cover data can be a critical component for Reducing Emissions from Deforestation and Forest Degradation (REDD+) policies. In this work, we determine the best threshold, compatible with the official Brazilian dataset, for establishing a

BioDinamica: a toolkit for analyses of biodiversity and biogeography on the Dinamica-EGO modelling platform [PDF]
PeerJ, 2019 Biogeography and macroecology are at the heart of the debate on ecology and evolution. We have developed the BioDinamica package, a suite of user-friendly graphical programs for analysing spatial patterns of biogeography and macroecology.

Towards a global understanding of tree mortality [PDF]
new phytologist.Summary Rates of tree mortality are increasing globally, with implications for forests and climate. Yet, how and why these trends vary globally remain unknown. Developing a comprehensive assessment of global tree mortality will require systematically integrating data from ground‐based long‐term forest monitoring with large‐scale remote sensing.

Biogeography of Amazon birds: rivers limit species composition, but not areas of endemism [PDF]
Scientific Reports, 2017 Amazonian rivers are usually suggested as dispersal barriers, limiting biogeographic units. This is evident in a widely accepted Areas of Endemism (AoEs) hypothesis proposed for Amazonian birds.

Past human‐induced ecological legacies as a driver of modern Amazonian resilience
People and Nature, Volume 5, Issue 5, Page 1415-1429, October 2023., 2023 Abstract People have modified landscapes throughout the Holocene (the last c. 11,700 years) by modifying soils, burning forests, cultivating and domesticating plants, and directly and indirectly enriched and depleted plant abundances. These activities also took place in Amazonia, which is the largest contiguous piece of rainforest in the world, and for
