The Impacts of the Activities of the International Non- Governmental Organizations on Post-Conflict Environmental Reconstruction in Monrovia, Liberia

This mixed-methods study of post-conflict Monrovia (2020–2024) reveals that while International Non-Governmental Organization activities significantly drive environmental reconstruction outcomes—particularly through community education and rehabilitation programs—they struggle to effect structural behavioral changes like waste management, highlighting the need for long-term investment frameworks to sustain recovery.

Identification of Hydrologic Landscapes in Brazilian river basins and their application as indicators of water yield and storage

This study applies the Hydrologic Landscapes classification method to the PCJ River Basins in southeastern Brazil, demonstrating that integrating relief, soil, aquifer, and climate data via GIS effectively identifies specific regions capable of simultaneously maximizing water yield and storage to guide sustainable water management in water-scarce areas.

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.

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.
