Environmental Filters of Waterbird Beta-diversity in Anthropogenic Landscapes: The Combined effect of Climatic and Environmental conditions

This study demonstrates that in anthropogenic landscapes, waterbird beta-diversity is primarily driven by species turnover rather than nestedness and is significantly shaped by the combined filtering effects of climatic and environmental conditions, despite a large proportion of unexplained variance.

Multi-cycle sedimentary processes govern black soil formation in the Sanjiang Plain, NE China evidence from grain size and geochemical constraints

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.

Research on 3D Spatial Localization and Prediction of Deep Concealed Ore Bodies Based on Graph Neural Networks and Multi- Source Geological Constraints

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.

Climate Change Impacts on Reference Evapotranspiration in Arid and Semi-Arid Regions under CMIP6 Scenarios using ERA5-Land and Machine Learning

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.

Western North Atlantic Sea level reveals enhanced future AMOC Weakening

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.

Environmental Gradients Drive Leaf Morphological Diversity in the Mangrove Avicennia marina across Coastal Wetlands of the Indian West Coast

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.

Fuzzy Logic-Based GIS Modeling of Malaria Risk in the Gedeo–Abaya Landscape of the Ethiopian Rift Valley

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.

Composition and molecular transformation mechanisms of dissolved organic matter in the Huai River (Anhui Section)

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.
