DNRA stimulates aerobic microbial processes and restructures the surface planktonic community in the Chilean OMZ

By integrating Dissimilatory Nitrate Reduction to Ammonium (DNRA) into a biogeochemical model of the Chilean coastal Oxygen Minimum Zone, the study reveals that while DNRA primarily redirects nitrogen toward recycling with minimal impact on oxygen levels, it unexpectedly lowers nitrite and ammonium concentrations through enhanced nitrification, thereby stimulating the growth of large phytoplankton and zooplankton in surface waters.

A Geology-Based Assessment of Mining Lease Adequacy and Land-Use Efficiency: A 3D Geological Modeling Case Study of a Manganese Deposit in the Eastern Ghats Mobile Belt, India

This study demonstrates that mining lease adequacy should be evaluated as a geological-operational property rather than a mere cadastral boundary by applying 3D geological modeling to the Sadanandapuram manganese deposit in India, revealing that the deposit's complex lensoidal geometry and high waste-to-ore ratio necessitate a land-use strategy that integrates orebody structure with sustainable mine planning.

Global Research Disparities in the Use of Indigenous Knowledge in Enhancing Species Conservation: A 25 -Year Bibliometric Analysis (2000 – 2025)

This 25-year bibliometric analysis reveals a significant increase in global research linking Indigenous knowledge to biodiversity conservation, yet highlights persistent geographical and taxonomic biases that necessitate a shift toward Indigenous-led partnerships and more equitable, inclusive research frameworks.

Study of soil salinity from geological, endorheic and anthropic origin in the Timimoun region (Algeria), and their impacts on soil pollution

This study identifies the geological and anthropic origins of soil and water salinity in the Timimoun region of Algeria, revealing that evaporite-rich parent rocks and the use of saline irrigation water drive secondary salinization, thereby highlighting the critical need for targeted management strategies to mitigate land degradation in arid oasis environments.

PM2.5-Bound Metals in a High-Tech Industrial Area of Northern Taiwan: Spatial Distribution, Sources, and Health Risks

This study reveals that PM2.5 in northern Taiwan's high-tech industrial region is dominated by metals from fossil fuel combustion, dust, industrial emissions, and traffic wear, posing significant non-carcinogenic risks to children and elevated cancer risks primarily driven by arsenic and chromium, thereby highlighting the need for source-specific controls beyond mere mass concentration monitoring.

Attribution of storm track activity to instantaneous upper-level jets yields new insights into the North Pacific midwinter minimum

By classifying instantaneous upper-level jets into subtropical and polar-front types, this study reveals that the North Pacific midwinter minimum in storm track activity is driven by the seasonal dominance of subtropical jets and the specific suppression of eddy amplitudes under polar-front conditions, rather than solely by climatological mean jet properties.

Integrated Geophysical Characterization of Weathered and Fractured Subsurface Zones for Groundwater Exploration inAbeokuta, Southwestern Nigeria

This study utilizes an integrated geophysical approach combining seismic refraction, EM-VLF, and electrical resistivity methods to characterize the subsurface weathered and fractured zones of Moshood Abiola Polytechnic in Abeokuta, Nigeria, identifying potential but limited groundwater-bearing horizons within the complex transition between crystalline basement and sedimentary environments.

Fault-aware local correction framework for stratigraphic surface reconstruction under geological discontinuities

This study proposes a fault-aware local correction (FLC) framework that integrates universal kriging with fault displacement modeling and distance-decay weighting to significantly improve the accuracy of stratigraphic surface reconstruction in geologically discontinuous regions while preserving regional stability.

Influence of Flow Regulation on Phytoplankton Biomass and Composition Along the Salinity Ecocline: Caloosahatchee River Estuary, Florida, USA​

This study demonstrates that varying discharge volumes from the C-43 Canal in Florida's Caloosahatchee River Estuary drive distinct shifts in phytoplankton composition and harmful algal bloom patterns along the salinity gradient, suggesting that optimized flow regulation could mitigate bloom intensity and duration.
