Chlorantraniliprole: bioactivation in coffee seedlings and control of resistant Leucoptera coffeella populations

open access: yesPest Management Science, EarlyView.
Chlorantraniliprole enhanced growth and biomass in coffee seedlings infested by susceptible Leucoptera coffeella, while resistant populations limited its insecticidal performance. These findings emphasize both the bioactivator potential of chlorantraniliprole and the challenges of managing resistance in coffee leaf miner control.

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

open access: yesRemote 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

open access: yesRemote 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

How Brazilian Public Universities Are Operationalizing The SDGs: Strategic Plans Analysis

open access: yesSustainable Development, EarlyView.
ABSTRACT Despite the importance of universities for Sustainable Development, only a handful of studies have evaluated the implementation levels of SDGs in HEIs in Latin America. To fill this void, this study examines the strategic plans of 70 Brazilian public universities, which account for 92.8% of Federal Universities.

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...
