Comparing geospatial interpolation techniques for estimating ambient PM2.5 mass concentrations from sugarcane burning in South Florida

Using a dense network of low-cost sensors in South Florida's Everglades Agricultural Area, this study evaluated geospatial interpolation techniques for estimating PM2.5 from sugarcane burning, finding that while inverse distance weighting performed best individually, a dynamic approach selecting the optimal model daily provided the most robust exposure estimates for future health research.

Independent Sentinel-2 mapping and mobility context of the 10 September 2024 Lang Nu debris avalanche (Lao Cai, Vietnam): a reproducible open-data workflow

This paper presents a reproducible open-data workflow using Sentinel-1 and Sentinel-2 satellite imagery to independently map the September 2024 Lang Nu debris avalanche in Vietnam, confirming its 0.66 km² extent and demonstrating its exceptional mobility (2.3 times the global mean) consistent with mechanisms of saturated deposit entrainment and velocity-weakening friction.

Voluntary national conservation payments retain biodiversity-relevant forest structure

This study provides quasi-experimental evidence that Finland's METSO voluntary payment program effectively retains biodiversity-relevant forest structure by significantly avoiding clear-cutting and improving stand characteristics, thereby demonstrating the success of market-based incentives in addressing forest degradation beyond simple deforestation.

A rising water table mobilizes deep, iron-bound soil phosphorus

This study reveals that seasonal rising water tables can mobilize traditionally inaccessible iron-bound phosphorus from deep soil layers, suggesting that many landscapes currently considered phosphorus-poor may actually possess significant, dynamic nutrient reserves driven by redox fluctuations.

Mechanistic Ecological Feedbacks in DICE 2023: Physical Divergence and Welfare Sensitivity

This study demonstrates that while incorporating mechanistic permafrost thaw feedbacks into the DICE 2023 model significantly increases projected global temperatures, the resulting welfare losses appear negligible under standard damage functions and discounting conventions, revealing that the model's insensitivity to ecological feedbacks stems from structural assumptions in its damage and discount parameters rather than the physical climate dynamics themselves.

Water repellency effects on the pore structure of wetland soils

This study demonstrates that in Chilean wetland soils, water repellency and pore structure recovery are coupled and depth-dependent, with topsoil exhibiting reversible behavior while subsoil undergoes irreversible changes due to drying beyond its historical matric potential range, a process primarily driven by organic carbon content.

Non-synchronous changes in water, carbon and habitat functions of alpine swamp meadows on the Qinghai–Tibetan Plateau and future risk hotspots

This study reveals that water yield, soil carbon storage, and waterbird habitat functions in Qinghai–Tibetan Plateau alpine swamp meadows have changed asynchronously over the past three decades, with spatial co-occurrence of high values failing to predict temporal stability, thereby identifying specific future risk hotspots where high current multifunctionality faces imminent degradation under climate change.
