Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1155-1171, May 2026.
Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...

Changing Aerodynamic Roughness in WRF Reduces Bias and Improves Accuracy in Near‐Surface Wind Simulations

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Accurate simulation of near‐surface wind speed is crucial for applications in renewable energy, dust emission, and air quality modeling. However, the Weather Research and Forecasting (WRF) model systematically over‐estimates 10 m wind speed due to simplified representations of surface roughness and momentum exchange.

Time to burn: landscape drivers of fuel trait variability and fire regime in savanna ecosystems

open access: yesOikos, Volume 2026, Issue 3, March 2026.
Fuel traits are important determinants of fire behavior and regime in savannas and, thus, of how fire affects plant communities. However, whether these traits are correlated, predictable and how they are influenced by biotic and abiotic drivers remain to be rigorously evaluated.

Record phenological responses to climate change in three sympatric penguin species

open access: yesJournal of Animal Ecology, Volume 95, Issue 3, Page 455-469, March 2026.
This paper is impressive because we managed to monitor extensively a really difficult place to reach and operate in. We deployed 77 cameras across Antarctica and the Sub Antarctic islands to monitor three different species of penguins. We found that they are the fastest advancing vertebrates with respect to their timing of breeding.

All Social Comparisons are Local? Inequality, Coethnicity and Subjective Economic Position

open access: yesSwiss Political Science Review, Volume 32, Issue 1, Page 156-176, March 2026.
Abstract Recent studies have found that the self‐perceived, rather than the objective, economic position affects individual political behavior. But how do individuals self‐assess their own position? In this paper, we study how local conditions – local inequality and coethnicity – affect this self‐assessment.

Unveiling the Crystal Structure of Sanidine: A Polarized Raman and Ab Initio Simulation Exploration

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 2, Page 227-238, February 2026.
This study combines polarized Raman spectroscopy and ab initio calculations to assign theoretical vibrational modes to observed spectra. Polarized Raman spectra were collected in six geometries (40–1200 cm−1). Theoretical predictions via DFT show good agreement with experiments, though some discrepancies point to influences like trace elements and ...
