Habitat loss reshuffles ecological and evolutionary interactions in a seed dispersal network

Oikos, EarlyView.
In tropical forests, habitat loss reshapes species composition, favoring generalists and recently emerged lineages while specialists and older evolutionary lineages are lost. However, how changes in species ecological attributes and evolutionary history affect ecological processes is poorly explored.

Performance of Land Use and Land Cover Classification Models in Assessing Agricultural Behavior in the Alagoas Semi-Arid Region

AgriEngineering
The scarcity of information on agricultural development in the semi-arid region of Alagoas limits the spatial understanding of this activity. Government data are generally numerical and lack spatial detail.

Brazil seed transfer zones: Supporting seed sourcing for climate‐resilient ecosystem restoration

PLANTS, PEOPLE, PLANET, EarlyView.
Brazil has tens of millions of hectares of degraded land that must be restored to meet national and global biodiversity and climate goals. Sowing genetically diverse native seeds is key to restoring degraded lands to climate‐resilient landscapes, but we still lack guidance on how to effectively match seed sources to restoration sites across broad ...

Improved Cerrado Wetland Mapping Through Seasonal Moisture Metrics, Terrain Information and Semantic Segmentation

Remote Sensing in Ecology and Conservation, EarlyView.
Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

frontiermetrics: An R Package for Characterizing Deforestation Frontiers

Remote Sensing in Ecology and Conservation, EarlyView.
Deforestation frontiers are major drivers of biodiversity loss, carbon emissions, and ecosystem degradation, yet our understanding of how deforestation progresses in these frontiers is limited. We present frontiermetrics, an R package to quantify a range of metrics describing the speed, severity, and spatio‐temporal patterns of forest loss. The package

Effects of changes in use and soil cover on real evapotranspiration from the creation of a remote sensing product in the Xingu basin

Revista Brasileira de Ciências Ambientais
Several studies have shown that changes in land cover within a given watershed significantly affect the hydrological cycle and its variables. In the Xingu basin, many areas had their vegetation replaced by agricultural crops and pastures, while ...

Illegal Gold Mining in the Brazilian Amazon: Environmental Degradation in Yanomami Indigenous Lands, and Regulatory Failures

Sustainable Development, EarlyView.
ABSTRACT Illegal gold mining has emerged as a major sustainability threat in the Amazon, eroding Indigenous rights, forest integrity, and climate mitigation efforts. This study examines how international market incentives relate to the expansion of illegal mining and associated deforestation within the Yanomami Indigenous Territory (YIT) from 2008 to ...
