Calibration of the SMAP Soil Moisture Retrieval Algorithm to Reduce Bias Over the Amazon Rainforest
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingSoil moisture (SM) is crucial for the Earth's ecosystem, impacting climate and vegetation health. Obtaining in situ observations of SM is labor-intensive and complex, particularly in remote and densely vegetated regions like the Amazon rainforest.

Self-amplified Amazon forest loss due to vegetation-atmosphere feedbacks
Nature Communications, 2017 Relatively little is understood about seasonal effect of climate change on the Amazon rainforest. Here, the authors show that Amazon forest loss in response to dry-season intensification during the last glacial period was likely self-amplified by ...

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 ...

Beyond forests: Harnessing conservation gardening for open biomes in Brazil
PLANTS, PEOPLE, PLANET, EarlyView.Urban gardening offers an innovative conservation strategy by integrating native ornamental species into urban landscapes. We evaluated the ornamental potential of the Brazilian flora by comparing the representation of species from forests versus open biomes (focusing on campo rupestre grasslands) and introduced and validated the Index of Ornamental ...

Unexpected seasonality in quantity and composition of Amazon rainforest air reactivity
Nature Communications, 2016 The degree to which biogenic volatile organic compounds released by the Amazon canopy impact oxidation capacity remains uncertain. Here, the authors evaluate the vertical distribution of total hydroxyl radical reactivity and individual trace gases in the

Correlation between Amazon deforestation and rainfall patterns in the Iguaçu River basin (Paraná, Brazil) [PDF]
Brazilian Journal of BiologyThe Amazon Rainforest plays a crucial role in regulating the South American hydrological cycle, particularly through moisture transport driven by the Low-Level Jets (LLJs), which connect the Amazon region to southern Brazil.

Sensitivity of the Amazon biome to high resolution climate change projections [PDF]
Acta Amazonica, 2016 : Despite the reduction in deforestation rate in recent years, the impact of global warming by itself can cause changes in vegetation cover. The objective of this work was to investigate the possible changes on the major Brazilian biome, the Amazon ...

PLANTS, PEOPLE, PLANET, EarlyView.It remains unclear how many plant species are not yet recorded by science. We illustrated the process by which species of the pineapple family in tropical America have been newly described to science to date, and we estimated how many species may still await scientific discovery in this group.
