Differences in Phenological Estimation From Multi‐Vegetation Indices Across the Yellow River Basin

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study evaluated the differential performance of PPI, kNDVI, and EVI in monitoring land surface phenology across the Yellow River Basin. The three vegetation indices showed pronounced divergence in capturing autumn phenological metrics, particularly the downturn date (DD) and recession date (RD).

Genetic Differences in Purple Finch (Haemorhous purpureus) Are Linked With Subspecies and Migratory Behaviour Differences

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
We used ddRADseq data to assess the genetic population structure of purple finch populations in North America. We found differences among and within subspecies. We also found genes that were under selection and associated with differences observed in subspecies and migratory phenotypes.

Geomorphological mapping of the Becca d'Aver deep‐seated gravitational slope deformation (Aosta Valley, Italy) based on multi‐scale and multi‐sensor analysis

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Geomorphological characterization of the DsGSD enables us to identify the sources of sediment that could be mobilized as debris flows. In the area, pseudo‐badlands morphotype has been defined and mapped, representing the main sources of risk beside abandoned quarry deposits.

Metabolic Reprogramming Analysis of Wheat Response to Low Temperature Stress Under Nitrogen Supply

open access: yesFood and Energy Security, Volume 15, Issue 3, May/June 2026.
Low temperature stress triggers a defense network that maintains growth at the expense of inhibiting photosynthesis and chlorophyll synthesis. Temperature recovery effectively repairs low temperature‐induced damage and enhances stress resistance, while nitrogen supply can further augment these protective processes to strengthen cold tolerance ...

Land Cover Change Drives River Flow Modifications in Central Chile

open access: yesHydrological Processes, Volume 40, Issue 5, May 2026.
This study examines the combined effects of land cover change and ENSO on streamflow dynamics in four coastal catchments of central Chile, using a 45‐year (1979–2023) dataset of remote sensing and hydroclimatic data. Conclusions Native forest loss reduced summer flows and PP–Q relationship; preserved forests enhanced resilience.
