Preservative Ethanol From Stomach Contents Is a Reliable Proxy for Diet DNA Metabarcoding

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
We tested whether DNA metabarcoding of preservative ethanol can substitute bulk stomach contents for reconstructing diets. Using two ethanol DNA extraction methods (precipitation and drying), the resulting profiles showed minor differences relative to each other and to bulk contents in richness, composition, and read counts, mostly limited to low ...

Stemflows and Preferential Flows: A Historical Review and Challenges for the Future

open access: yesHydrological Processes, Volume 40, Issue 5, May 2026.
Possible implementation of stemflow in the MIPS model where all water in the system is represented as particles in pathways of specified velocity. Stemflow (green particles) can be treated as a localised input with probabilities of entering higher velocity pathways than throughfall, depending on the input rates.

Comparing ERA5‐Land and BR‐DWGD Datasets and Their Impacts on Vadose‐Zone Hydrological Modelling in the Brazilian Cerrado

open access: yesHydrological Processes, Volume 40, Issue 5, May 2026.
We compared ERA5‐Land and BR‐DWGD datasets for climate trend analysis and vadose zone hydrological simulations in the Brazilian Cerrado. Bias correction improved the representation of daily meteorological variables in ERA5‐Land. Although long‐term climate change signals were consistent between the datasets, inherent errors in ERA5‐Land propagated ...

Heat and Cold Waves in Brazil: An ERA5‐Based Analysis of Trends and Seasonality (1980–2024)

open access: yesInternational Journal of Climatology, Volume 46, Issue 6, May 2026.
This study uses ERA5 reanalysis data to assess changes in extreme heat and cold events across Brazil from 1980 to 2024. Results reveal a sharp increase in heatwave frequency and a general decline in coldwave occurrences, though regional variations are substantial.

Dry–Hot Compound Events Driving the 2024 Pantanal Wildfires

open access: yesInternational Journal of Climatology, Volume 46, Issue 6, May 2026.
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.

Dry‐Season Water Deficits in the Southwestern Amazon Under High Emissions

open access: yesInternational Journal of Climatology, Volume 46, Issue 6, May 2026.
Projected climatic water deficit in the study region indicates a longer and more intense dry season, with delays in the onset of the wet season under higher emission scenarios. These changes, particularly, pronounced under SSP5‐8.5, suggest increased ecological vulnerability and greater seasonal water stress.

Local valuation of ecosystem services from protected areas along a forest–savanna gradient in West Africa

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1419-1436, May 2026.
Abstract Understanding how local communities perceive and prioritise ecosystem services (ES) across diverse ecological contexts is essential for improving protected area (PA) management. However, most studies focus on single ecosystems and lack cross‐ecological comparisons. This study aimed to explore how communities living in and around PAs in Ghana's
