How Do Exports and Imports Drive Per Capita Carbon Emissions? A Spatial Panel Analysis of the Persian Gulf Region

This spatial panel analysis of seven Persian Gulf countries from 1995 to 2020 confirms the Environmental Kuznets Curve hypothesis and reveals that both exports and imports significantly increase per capita CO₂ emissions, with imports having a stronger impact, thereby urging policymakers to adopt cleaner production technologies and carbon-efficient trade structures to mitigate environmental degradation.

Wildfire-induced nutrient redistribution drives depth-dependent functional decoupling and network destabilization

This study demonstrates that wildfire in subtropical forests drives depth-dependent functional decoupling and network destabilization, where increasing fire severity enriches nitrogen and phosphorus cycling while reducing carbon degradation in surface soils and disrupting microbial interaction networks, whereas deeper soil layers remain comparatively buffered from these effects.

Taxonomic and paleoenvironmental reinterpretation of Cambrian (Series 2, Stages 3-4) calcimicrobe-archaeocyath reefs from north- western Sonora (Mexico)

This study reinterprets the depositional environment of the Cerro Rajón section in northwestern Sonora as an upper offshore ramp setting and refines the local archaeocyathan taxonomy by identifying synonyms, thereby clarifying the paleogeographic continuity of these early Cambrian reefs with the broader Laurentian margin.

Taxonomic and functional representations of phytoplankton beta diversity show contrasting sensitivity to environmental gradients in a tropical reservoir

This study demonstrates that in a tropical reservoir, the choice of phytoplankton community representation (taxonomic, functional groups, or trait-based) significantly alters the detected magnitude and seasonal consistency of environmental associations, revealing practical trade-offs rather than a single superior approach for interpreting ecological structuring.

Integrated Geological, Geophysical, and Geotechnical Site Characterization of Ajima Dam Site, Amhara Region, Ethiopia: Implications for Seepage and Foundation Stability

This study presents an integrated geological, geophysical, and geotechnical characterization of the Ajima Dam site in Ethiopia, revealing critical foundation stability and seepage risks due to insufficient bearing capacity and high permeability, and recommending specific mitigation measures such as deep excavation, curtain grouting, and seismic-resistant design modifications.

Atmospheric transport reshapes cross-administrative methane attribution from Shanxi coal basins to Beijing-Tianjin-Hebei

By integrating satellite-constrained inventories with atmospheric modeling, this study reveals that transboundary methane transport from Shanxi coal basins significantly amplifies the Beijing-Tianjin-Hebei region's methane burden, particularly during specific wind events, thereby demonstrating the critical need for cross-administrative governance strategies that account for atmospheric transport rather than relying solely on jurisdiction-limited controls.

How exposed is the Maldivian food system to climate risk? Evidence from a long-term Material Flow Analysis (MFA)

This study reveals that the Maldivian food system has become critically vulnerable to climate and external shocks due to a massive increase in import dependency and a shift toward ultra-processed foods, highlighting the urgent need for systemic interventions to strengthen domestic production and food security.
