This study demonstrates that black soil formation in the Sanjiang Plain, NE China, is governed by multi-cycle sedimentary processes involving the erosion, transport, and deposition of well-sorted parent material derived from the Wandashan Mountains during the mid-Holocene, rather than being a product of first-order weathering.
This paper proposes a graph neural network-based framework that integrates multi-source geological data and mineralization knowledge constraints to overcome the limitations of conventional methods in accurately localizing and predicting deep concealed ore bodies under conditions of sparse data and high geological uncertainty.
This study projects that climate change in Iran's arid Semnan Province will significantly increase reference evapotranspiration by up to 16% by the end of the century, particularly in agricultural zones, under CMIP6 scenarios, necessitating urgent adaptive water management strategies.
This study introduces a coastal sea-level gradient index as a robust proxy for Atlantic Meridional Overturning Circulation (AMOC) variability, revealing that observationally constrained climate models project a significantly stronger weakening of the AMOC by 2100 under both high and low emissions scenarios compared to previous IPCC assessments.
This study identifies a unique, long-lived low-δ18O magmatic event between 920 and 680 Ma driven by Neoproterozoic continental extension, which facilitated both shallow meteoric water circulation and deep crustal recycling of seawater-altered mafic rocks.
This study demonstrates that hydroclimatic and hydrological gradients, particularly temperature, precipitation, humidity, salinity, and tidal amplitude, significantly drive leaf morphological diversity in *Avicennia marina* populations along the Indian west coast through a combination of local adaptation and phenotypic plasticity, providing a scientific basis for targeted mangrove conservation and climate-resilient wetland management.
This study introduces a novel fuzzy logic-based GIS modeling approach to map malaria risk in the Ethiopian Rift Valley's Gedeo–Abaya landscape, demonstrating that spatially continuous risk surfaces derived from fuzzified environmental and demographic factors provide more ecologically realistic and actionable insights than conventional crisp classification methods.
This study elucidates the spatiotemporal heterogeneity and molecular transformation mechanisms of dissolved organic matter in the Anhui section of the Huai River using 3D-EEMs-PARAFAC and FT-ICR MS, revealing seasonal shifts from autochthonous tryptophan-like substances to refractory humic compounds and identifying specific molecular pathways that inform water treatment optimization and risk mitigation.
This study demonstrates that the acute toxicity of fixed-ratio cadmium chloride–glyphosate potassium binary mixtures in sub-adult African catfish (*Clarias gariepinus*) increases significantly with exposure duration, resulting in a 96-hour LC₅₀ of 28.100 mg/L and establishing preliminary safe exposure thresholds of 2.81 mg/L and 0.28 mg/L to inform environmental risk assessments.
This study reanalyzes the 2023 Shishaldin Volcano eruption using the Ash3d model to demonstrate how unknown tephra grain sizes and the distinct behavior of pyroclastic density current-generated plumes complicate operational ash dispersion forecasting for remote mafic eruptions.
