Satellite-Based Assessment of Vegetation and Hydrological Dynamics at the Garâa of Sejnane Ramsar Wetland (Tunisia): A Multi-Temporal NDVI and NDWI Analysis

This study utilizes a 32-year multi-temporal analysis of Landsat satellite data to reveal that the Garâa of Sejnane Ramsar wetland in Tunisia is experiencing a significant long-term drying trend and a shift in vegetation dynamics, driven by seasonal hydrological changes, agricultural expansion, and climate change.

Evaluating Sediment Resuspension and Internal Nutrient Loading in Tappan Lake Using Remote Sensing, Acoustic Doppler Current Profiler Observations, and EFDC+ Modeling

This study integrates remote sensing, acoustic Doppler current profiler observations, and EFDC+ modeling to demonstrate that wind and flow-driven sediment resuspension in Tappan Lake's mid-lake zone is the primary driver of internal nutrient loading and persistent algal blooms, independent of external watershed inputs.

From Hazard to Heritage: Landslides Risks, Geoheritage Potential, and Geotourism Opportunities along NH-44 corridor, Jammu and Kashmir, India

This study analyzes the Ramban-Banihal section of NH-44 in Jammu and Kashmir by mapping its high landslide susceptibility driven by tectonic and geological factors, while simultaneously proposing a transformative framework that reframes this hazard-prone corridor as a valuable geoheritage site for geotourism, education, and sustainable development.

Linking Groundwater Depletion to Land Subsidence; An Integrated Approach Using D- InSAR, Fuzzy Logic, and Machine Learning in the Isfahan-Borkhar Plain, Central Iran

This study integrates D-InSAR observations with fuzzy logic and machine learning models to map land subsidence potential in Iran's Isfahan-Borkhar plain, demonstrating that Support Vector Machines (SVM) achieve the highest accuracy (R² = 0.93) in linking groundwater depletion to surface deformation for improved hazard mitigation.

Geological controls and migration mechanisms of gas in fractured non- coal-measure strata: Insights from mountainous tunnel investigations in the western Sichuan Plateau

This study investigates gas migration mechanisms in fractured non-coal-measure strata of the western Sichuan Plateau by integrating field investigations and 3D numerical modeling to propose a geological source-pathway-opening framework that elucidates how structural connectivity and excavation disturbances control gas accumulation and transport in deep underground tunnels.

Buffalo Grazing Effects on the Physical–Mechanical Quality and Load-Bearing Capacity of Hydromorphic Riparian Soils in the Brazilian Atlantic Forest​

This study demonstrates that intensive buffalo grazing on hydromorphic riparian soils in the Brazilian Atlantic Forest significantly increases soil erodibility and structural vulnerability to moisture-induced compaction compared to native vegetation, highlighting the critical role of grazing management in preserving floodplain soil quality.

Changing patterns of heat waves and population exposure in India, 1980-2024

This study introduces the Entropy Weighted Heat Wave Peril Index (E-HWPI), a novel six-component metric incorporating nocturnal heat stress and antecedent drought conditions to provide a spatially explicit, data-driven assessment of heat wave hazards and population exposure across India from 1980 to 2024, identifying five northern states as facing extreme risk.

Climatic context shapes contrasting insect richness responses to elevation across Europe

By analyzing standardized insect data across seven European elevational gradients, this study demonstrates that contrasting richness-elevation patterns are driven by the specific climatic position of each transect and the phylogenetic structure of taxa, suggesting that accurate biodiversity forecasting under climate change requires accounting for both local climatic context and evolutionary history.

Trait-mediated nutrient resorption reveals element-specific conservation strategies in mangroves

This study of ten mangrove species in Hainan, China, reveals that nutrient resorption efficiency is highly element-specific and driven primarily by internal leaf nutrient concentrations and anatomical traits rather than soil nutrients, with conservation strategies further modulated by seasonal changes and salt-regulation mechanisms.
