Drivers of honeybee forage supply across contrasting land covers in forested Patagonia

This study demonstrates that in the forested regions of Patagonia, vegetation structure and land use—particularly canopy cover and grazing pressure—are stronger drivers of honeybee forage composition and origin than environmental factors, with higher canopy cover favoring native species and grazing promoting exotic ones.

Ice contributed only 53% to the flood triggered by the 2026 Langtang Lirung rock-ice avalanche in Nepal

This study reconstructs the 2026 Langtang Lirung rock-ice avalanche to demonstrate that while melting ice contributed only 53% of the resulting flood volume, the mobilization of pre-existing river water and erodible deposits along the corridor was the primary driver of the downstream surge, highlighting the need to include these factors in hazard assessments.

Occurrence and Distribution of Microplastics in Hydrologically Connected River–Reservoir Systems: Tepeji–Requena and Tula–Endhó, Mexico

This study investigates microplastics in two hydrologically connected river–reservoir systems in central Mexico, revealing that reservoirs act as accumulation zones for predominantly fiber-shaped contaminants and highlighting the necessity of interpreting microplastic occurrence alongside local hydrological and water-quality conditions.

Modelling the hydrological impacts of catchment land use change on a valley peatland in the French Massif Central

A coupled MIKE SHE/MIKE 11 modeling study in the French Massif Central demonstrates that replacing broadleaf woodland with conifer plantations significantly reduces water inflow and stream discharge to a valley peatland, whereas converting to grassland or heathland increases these hydrological inputs.

Improving Greenhouse Gas Emission Calculation Accuracy in the Oil and Gas Industry in the context of Indonesia

This study demonstrates that implementing high-resolution, field-verified IPCC Tier 3 accounting at Pertamina's CPP Gundih facility corrects a significant overestimation of greenhouse gas emissions, thereby reducing Indonesia's projected carbon tax liability by up to six-fold and revealing the superior financial resilience of the Gross Split fiscal regime compared to Cost Recovery in the face of climate policy.

Environmental Drivers of low Calf Survival in Indo-Pacific bottlenose dolphins (Tursiops aduncus) in an Australian Marine Protected Area

This study reveals that Indo-Pacific bottlenose dolphin calves in the Adelaide Dolphin Sanctuary suffer from exceptionally low survival rates, with storm events significantly increasing mortality risk and marine heatwaves showing a concerning, though statistically non-significant, positive association with death, highlighting the population's vulnerability to climate-driven environmental changes.

Mapping bar-sand coastal aquifer structure and saltwater intrusion mechanisms using Electrical Resistivity Tomography: a case study fromBinh Thuan coast, south-central Vietnam

This study utilizes Electrical Resistivity Tomography (ERT) along the Binh Thuan coast of Vietnam to map the subsurface structure of bar-sand coastal aquifers and identify four distinct saltwater intrusion mechanisms, including direct marine intrusion, shrimp-farming contamination, relic mining pollution, and compound river-mouth effects, which are corroborated by hydrochemical data.

High-Resolution Air Quality Modeling over Santiago, Chile: A Comparative Assessment of EDGAR and INEMA Anthropogenic Emission Inventories

This study evaluates the impacts of using global (EDGAR) versus regional (INEMA) anthropogenic emission inventories on high-resolution air quality modeling in Santiago, Chile, revealing that while both yield similar overall PM2.5 emissions, they produce distinct source apportionment and sensitivity structures, with EDGAR highlighting industrial influences and INEMA emphasizing transport contributions.
