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.

Water Cut Rise Characteristics of Production Wells in Carbonate Reservoirs Based on Production Data Analysis

This study analyzes production data from a Middle Eastern carbonate oilfield to establish normalized water cut rise curves, revealing that reservoir pore structure and fracture development are the primary factors controlling the predominantly "convex" and "convex-S" water cut rise patterns, thereby providing a theoretical basis for optimizing water injection strategies.

Impact of COVID-19 on Water Use, Wastewater Flows, and Air Pollution: A LongTerm Monitoring Study

This study analyzes Lithuanian data from 2014 to 2024 to reveal that while the COVID-19 pandemic temporarily altered water use and air pollution patterns, it ultimately redistributed rather than reduced environmental pressures, underscoring the need for structural solutions to achieve long-term sustainability.

Substantial Shortwave Direct Radiative Forcing by Airborne Tire Wear Particles

This study utilizes valence electron energy loss spectroscopy and radiative transfer modeling to demonstrate that airborne tire wear particles are significant light-absorbing aerosols with a global shortwave direct radiative forcing of 0.0148 W m⁻², suggesting they will become an increasingly important contributor to anthropogenic climate warming as the global vehicle fleet shifts toward heavier electric models.

The multidecadal delay of the Baltic Sea ecosystem recovery

Using a 69-year dataset, this study reveals that the Baltic Sea's deep basins are trapped in an alternative stable state driven by a 14-to-19-year lag in internal phosphorus release, proving that legacy effects rather than external nutrient reductions currently dictate ecosystem recovery and necessitating a recalibration of global marine management timelines.
