Mafic–Ultramafic Tyulkulam Massif, West–Central Asian Orogenic Belt (Central Kazakhstan): Mineralogical and Geochemical Evidence for Transition from Forearc to Island-Arc Magmatism during the Evolution of the Junggar–Balkhash Ocean

This study presents the first comprehensive mineralogical and geochemical analysis of the Tyulkulam Massif in Central Kazakhstan, revealing that its ultramafic-mafic rocks record a tectonomagmatic evolution from forearc to island-arc settings during the early development of the Junggar–Balkhash Ocean.

Forest gain across tropical and subtropical Asia masks widespread loss of complex forests

Although forest cover has expanded across tropical and subtropical Asia, this gain largely masks a critical shift toward low-complexity forests and the continued loss of high-complexity ecosystems, underscoring the urgent need to prioritize structural quality over mere area in conservation monitoring.

bioDYM: Dynamic material flow analysis for biogenic carbon management and CDR strategy assessment

The paper introduces bioDYM, an open-source dynamic material flow analysis software built on the ODYM framework that enables flexible modeling of biogenic carbon systems and CDR strategies, demonstrating its effectiveness through a German wheat straw case study that highlights the critical impact of carbon stability and product lifetime on long-term carbon removal performance.

The distribution of movable fluid and its coupling influencing factors in ultra-low permeability sandstone reservoirs: a case study of Chang 6 member, Wuqi area, Ordos Basin

This study analyzes the distribution and influencing factors of movable fluids in the ultra-low permeability Chang 6 member of the Ordos Basin, revealing that movable fluid saturation is strongly correlated with pore-throat characteristics and that the development of micron-scale pore-throats is the key factor distinguishing these reservoirs from tight sandstones.

Forward-Modeling-Driven Quantification of Karst ERT Responses and Borehole-Constrained AI-Assisted Interpretation

This study establishes a forward-modeling-driven framework to quantify geometric distortions in karst ERT pseudosections and demonstrates that while AI-assisted interpretation suffers from inherent response artifacts, the integration of borehole constraints significantly improves anomaly detection accuracy, provided the boreholes intersect the target.

Spatial and Temporal Characteristics of Total Cloud Cover Over Bali, Indonesia, Using ERA5 Reanalysis Data (2016–2025)

This study utilizes ERA5 reanalysis data from 2016 to 2025 to characterize the spatial and temporal variability of Total Cloud Cover over Bali, revealing higher cloudiness in mountainous interiors, distinct monsoon-driven seasonal cycles, no significant long-term trends, and a strong ENSO influence during monsoon transition periods.

Utilization of Earth Observation and Ocean Modeling to Quantify Climate-Biogeochemical Interactions in a Vulnerable West African Coastal : Case of the East Coast of Cotonou in Benin

This study integrates field-based ecological analyses with a systematic review to demonstrate that coastal ecosystems in the Gulf of Guinea, specifically the East Coast of Cotonou, are undergoing a regime shift toward macroalgal dominance driven by synergistic nutrient enrichment and sea surface temperature anomalies, highlighting the critical role of structural complexity in maintaining ecosystem resilience against coupled climate and anthropogenic stressors.

Remote Sensing-Based Baseline Assessment of Reef Extent, Thermal Stress, and Anthropogenic Pressure for the Newly Designated Great Reef Protectorate, Red Sea, Egypt

This paper establishes the first satellite-derived baseline for Egypt's newly designated Great Reef Protectorate in the Red Sea, integrating 54.0 km² of mapped shallow reef extent, a record-breaking 2024 thermal stress event reaching 23.4 °C-weeks, and a 483% increase in coastal built-up area since 1990, while confirming the region's persistently oligotrophic conditions.
