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 ...

Grass species and climatic season impact on Rhipicephalus microplus temporal abundance in a tropical region

Pest Management Science, EarlyView.
The interaction between grass species and climatic season shapes the population dynamics of the cattle tick, Rhipicephalus microplus. This information highlights the potential of forage species to influence off‐host tick dynamics. Additionally, minimum temperature and minimum relative humidity were the most influential microclimatic predictors of ...

Seasonal Variation in Carbon Dynamics in the Lower Tocantins River: Influence of Discharge and Environmental Drivers

River Research and Applications, EarlyView.
ABSTRACT Tropical rivers play a key role in regional carbon budgets, yet greenhouse gas (GHG) dynamics in regulated systems remain poorly understood. This study investigates the seasonal variability of carbon dioxide (CO2) and methane (CH4) concentrations, isotopic composition (δ13C), and river‐atmosphere fluxes in the lower Tocantins River, a ...

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
