Geochemical characteristics and microscopic analysis of the Late Jurassic organic-rich carbonates in the Shabwah depression, southeastern Yemen: implications for organic matter input and depositional settings

This study investigates the Late Jurassic organic-rich Lam Member in Yemen's Shabwah depression, revealing that elevated organic matter and sulfur levels, supported by specific biomarker and microscopic evidence, indicate a marine depositional environment characterized by anoxic, sulfidic conditions and high bioproductivity driven by a warm climate, which facilitated the accumulation of marine-derived organic matter.

Long-term impact of prescribed burning on soil labile carbon and nitrogen pools in suburban forest ecosystems of subtropical Australia

This study on suburban forests in subtropical Australia found that while hot water extractable carbon and nitrogen pools and microbial biomass carbon recovered 9–14 years after prescribed burning, water extractable carbon and nitrogen pools and microbial biomass nitrogen remained unrecovered during the same period.

Spatiotemporal Evolution and Multi‑Scenario Simulation of Urban Ecological Resilience in the Middle-Reaches of the Yangtze-River

This study evaluates the spatiotemporal evolution of ecological resilience in the Middle-Reaches Urban Agglomeration of the Yangtze River from 2010 to 2020 and simulates its 2035 trajectory under three development scenarios, revealing that while resilience has generally improved, economic prioritization threatens ecological stability and necessitates optimized spatial planning to balance urban growth with environmental protection.

Interannual variability of tropical cyclone systems' landfall over Mozambique and its relationship with atmospheric conditions

This study analyzes the increasing interannual trend of tropical cyclone landfalls in Mozambique from 1971 to 2025, revealing that their frequency and timing are significantly driven by large-scale atmospheric moisture convergence and modulated by climate modes such as the Southern Annular Mode and Indian Ocean Dipole.

Radon Migration Mechanism in Straw-Amended Soil under Coupled Thermal-Structural Actions: Temperature Regulation on Pore Reconstruction and Radon Exhalation Threshold Effect

This study demonstrates that combining 6% corn straw incorporation with 600°C heat treatment significantly reduces soil radon exhalation by 26.3%–34.3% through the transformation of micropores into larger pores and the regularization of pore walls, establishing a critical threshold for effective low-radon soil improvement.

More than carbon: Soil organic carbon and cation exchange capacity as key indicators of chemical recovery in tropical montane Atlantic Forest soils

This study demonstrates that in tropical montane Atlantic Forest soils, soil organic carbon (SOC) and cation exchange capacity (CEC) are superior indicators of chemical recovery and resilience compared to conventional fertility metrics, as their restoration-driven increases directly enhance nutrient retention despite persistent soil acidity.

Microphytobenthos primary production and organic matter mineralization along the sea level gradient in a tropical mudflat

This study demonstrates that in a tropical mudflat, microphytobenthos biomass, community composition, and sediment biogeochemistry exhibit distinct zonation along the sea-level gradient, driven by factors like mangrove inputs and emersion time, which ultimately dictates the spatial variation in primary production and organic matter mineralization essential for scaling coastal ecosystem dynamics.

Multi-Scale Uncertainty Propagation in Energy Geostructures: From Interface Mechanics to Urban Geothermal Systems, Urban Thermal Resilience, and Subsurface Urban Heat Island Mitigation

This paper presents a novel multi-scale synthesis of uncertainty propagation in energy geostructures, demonstrating how uncertainties originating at soil–structure interfaces cascade through thermo–hydro–mechanical processes to impact district-scale geothermal systems and urban thermal resilience, while proposing integrated frameworks that leverage advanced probabilistic methods and artificial intelligence to enable reliable, climate-resilient infrastructure design.
