Egypt’s protected-area network at the land–sea interface: coastal reserve fragmentation, the 30×30 gap, and Lessepsian bioinvasion (1983–2022)

This study evaluates Egypt's protected-area network from 1983 to 2022, revealing that while the total area has expanded significantly, the system remains highly unequal and fragmented with a coastal sub-network that is underrepresented and vulnerable to Lessepsian bioinvasion, necessitating a strategic shift from mere area accumulation toward improving connectivity, representativeness, and management effectiveness to meet the Kunming–Montreal Global Biodiversity Framework's 30×30 target.

Nocturnal UTCI Heat Duration and Next-Day Active-Mobility Use: A Behavior-Day Monitoring Framework

This study proposes a behavior-day monitoring framework that aligns nocturnal heat exposure (defined as UTCI ≥ 28°C from 20:00 to 05:59) with next-day active mobility, demonstrating that while this metric captures high-heat-tail information, its effect is not independent of broader daytime heat patterns.

Development of Earthquake Early Warning (EEW) System: Empirical relationship using data from Japan

This study utilizes strong motion data from 143 Japanese earthquakes (2010–2024) to establish empirical relationships between various P-wave parameters and earthquake magnitude, demonstrating that a 5-second analysis window combined with multiple parameters significantly enhances the reliability of magnitude estimation for Earthquake Early Warning systems.

Deep impact: invasive non-native trees alter the entire soil profile in montane forests invaded by Ligustrum lucidum

This study demonstrates that the invasion of *Ligustrum lucidum* in subtropical mountain forests significantly alters chemical and physical soil properties, including nutrient availability and bulk density, throughout the entire soil profile down to 50 cm depth, thereby creating a distinct belowground environment with potential consequences for ecosystem functioning and native vegetation recovery.

GeoExtractor: A Framework for Structured Information Extraction from Geoscientific Literature

This paper introduces GeoExtractor, a large language model-powered multi-agent framework that employs a hierarchical extraction strategy to automatically convert unstructured geoscientific literature into structured data, significantly outperforming existing methods and successfully reconstructing known tectonic patterns from a compiled database of zircon analyses.

Marine Heatwave-Induced Stratification Promoted Subsurface Heat Storage and Supported the Rapid Intensification of Tropical Cyclone Winston

This study reveals that a marine heatwave-induced shallow mixed layer and enhanced stratification during Tropical Cyclone Winston (2016) facilitated the accumulation of subsurface heat, which was subsequently entrained by storm-induced mixing to sustain elevated energy fluxes and drive the cyclone's rapid intensification.

Vertical Structure and Evolution of Large-Scale Subsurface Marine Heatwaves

By applying a four-dimensional event-tracking framework to global ocean reanalysis data, this study characterizes the vertical structure and evolution of over 500 large-scale subsurface marine heatwaves, revealing seven distinct types driven by the interplay between large-scale climate variability (such as ENSO) and local ocean stratification.

Monitoring the Success of a Coastal Dune Restoration with Citizen Science

This three-year study on Tybee Island demonstrates that citizen scientists can effectively monitor coastal dune restoration, revealing that while restored dunes achieve comparable vegetation and sand accumulation to established dunes under normal conditions, they remain more vulnerable to extreme hurricane events.
