Paleoclimatic drivers of Acropora palmata populations across Caribbean Reefs over the last 6000 Years

This study utilizes a 6,000-year paleoclimate record and Generalized Additive Modeling to demonstrate that *Acropora palmata* populations across the Caribbean have historically experienced non-linear, geographically divergent fluctuations driven by natural climate variability, indicating that recent anthropogenic declines are part of a longer pattern of instability rather than an unprecedented event.

Radioactivity concentrations in Soils in Beijing, China from 2019 to 2025

This study analyzed 137 soil samples from all 16 administrative districts of Beijing between 2019 and 2025, finding that natural radionuclide concentrations (²²⁶Ra, ²³²Th, ⁴⁰K) were generally consistent across years but higher in mountainous areas, while artificial ¹³⁷Cs levels remained low, indicating no significant industrial releases and overall values within global ranges.

A Two-Stage Framework for Urban Earthquake Vulnerability Assessment: Integrating Social and Built Environment Indicators

This paper presents a two-stage framework for assessing urban earthquake vulnerability in Siliguri, India, by integrating a city-wide Social Vulnerability Index with a detailed Built Environment Vulnerability Index to reveal critical mismatches and compound risks, particularly highlighting the strong correlation between social disadvantage and post-earthquake road inaccessibility.

Random Forest-Based Prediction of Geothermal Heat Flow in the Arabian-Nubian Shield: A Multi-Proxy Satellite Geophysical Approach

This study presents the first spatially continuous geothermal model for the Arabian-Nubian Shield by employing a Random Forest algorithm integrated with sixteen multi-proxy satellite geophysical predictors to map terrestrial heat flow, identify high-potential geothermal zones, and guide future carbon-reduction energy development.

Distribution Characteristics and Controlling Mechanisms of Radon and Primordial Radionuclides in a Certain Impact Crater in China

This study investigates the spatial distribution and controlling mechanisms of radon and primordial radionuclides in a Chinese impact crater, revealing that granite lithology, impact-induced fragmentation, and environmental factors drive higher radioactivity in the crater core and granite compared to peripheral zones, while identifying sediment as the primary radon reservoir with low radiological risk in surface water.

Meta-analysis of biochar-driven changes in soil antibiotic resistance genes: toward mitigation strategies

This global meta-analysis demonstrates that biochar application reduces soil antibiotic resistance gene abundance by an average of 78.2%, identifying optimal mitigation thresholds such as a 0.5% dosage, near-neutral pH conditions, and specific feedstock properties to guide context-specific strategies for controlling antibiotic resistance.

Characteristics of drought and flood disasters in the southern part of the Dabie Mountains during the Ming and Qing dynasties and their response to climate

This study analyzes 139 historical drought and flood events in Tuanfeng County during the Ming and Qing dynasties, revealing their multi-periodic characteristics and distinct responses to global climate factors such as El Niño and temperature fluctuations, where droughts correlate with warm periods and floods with cold periods.

A systems thinking approach to improve participatory processes in small-scale fisheries management

This paper presents a practical decision-support framework that integrates participatory systems mapping with network analysis to help stakeholders in data-poor small-scale octopus fisheries in Peru and Chile identify key sustainability goals, evaluate intervention strategies, and prioritize monitoring indicators for adaptive management.

Fossil Carbon Transformation in Municipal Wastewater Treatment and Its Implications for Greenhouse Gas Accounting

This study integrates radiocarbon analysis and online monitoring to demonstrate that fossil carbon from municipal wastewater contributes significantly to direct greenhouse gas emissions, accounting for up to 52% of emissions at individual plants and approximately 10% of China's total sectoral emissions, thereby highlighting the need to distinguish fossil-derived CO₂ from biogenic sources in carbon accounting and decarbonization strategies.
