Methane and Nitrous Oxide Reshape the Air‐Water Greenhouse Gas Budget of a Tropical Estuarine Delta
Abstract Estuaries are important sources and sinks of greenhouse gases (GHGs), yet assessments of their radiative balance often focus primarily on carbon dioxide (CO2), with less attention given to methane (CH4) and nitrous oxide (N2O). We combine measurements of CH4 and N2O air‐water fluxes with concurrent CO2 data in a tropical estuarine delta ...

Climate Predicts Tree Dispersal Strategies Across Brazil's Ecosystems
ABSTRACT Aim We investigate the distribution of dispersal modes—endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and ...

Dry–Hot Compound Events Driving the 2024 Pantanal Wildfires
Extreme wildfires in the Pantanal in 2024 were driven by a cascade of heatwaves, rainfall deficits and the absence of the annual flood pulse. These conditions dried soils and rivers, enhanced fuel accumulation and enabled early and intense fire outbreaks.
