Climate and Land Cover Driven Redistribution of Water Balance in Bengaluru’s Source Watersheds: Implications for Regional Water Security

This study utilizes an ensemble of CMIP6 models and dynamic land cover projections to demonstrate that climate and land cover changes in Bengaluru's source watersheds will intensify the spatial and seasonal redistribution of water surplus toward runoff and infiltration pathways, thereby amplifying regional hydrological heterogeneity and posing significant challenges for future water security planning.

Dominant Role of Arbor Forests in Carbon Sink Enhancement: Dynamics and Drivers of Vegetation Carbon Storage in Pingxiang, China

Based on forest inventory data from 2003 to 2019, this study reveals that Pingxiang City's forest carbon storage more than doubled, driven primarily by the rapid expansion and improved density of young and middle-aged arbor plantations, which now constitute the dominant carbon sink supporting regional carbon neutrality goals.

Occurrence, fate, removal efficiency and ecological risk of selected antibiotics in wastewater and surface water of some hospitals: A case study in Vietnam

This study evaluates the occurrence, removal efficiency, and ecological risks of quinolone, macrolide, and β-lactam antibiotics in Vietnamese hospital wastewater and surrounding surface waters, revealing high contamination levels, variable treatment performance with AAO+MBR being most effective, and significant ecological risks primarily driven by ciprofloxacin.

Impact of geomagnetic storm intensity on thermospheric density and orbital decay of LEO satellites: a G1–G5 per-event analysis

This study analyzes 22 geomagnetic storms from 2003 to 2024 using a per-event approach to demonstrate that orbital decay rates for low-Earth-orbit satellites scale monotonically with storm intensity and are modulated by altitude, resulting in a high-accuracy empirical model that supports improved orbit prediction and collision avoidance strategies.

Selective survival at the Cretaceous–Paleogene boundary driven by infrared radiation and climate cooling

This study proposes that the selective survival of terrestrial animals at the Cretaceous–Paleogene boundary was driven by immediate mortality from infrared radiation and subsequent short-term climate cooling, which restricted habitable environments to limited temperate refugia that shaped the differential survival and migration patterns of birds, crocodilians, and mammals.

Operationalizing the Urban Biotechnosphere Framework for Coastal Resilience Assessment: A Case Study of Manta, Ecuador

This paper applies the urban biotechnosphere framework to Manta, Ecuador, revealing that between 2010 and 2024, integrated urban development exceeded the city's natural-regulating capacity by 24.80% due to significant declines in spatial-environmental quality and natural components, thereby highlighting the urgent need for a coordinated territorial agenda to restore ecological equilibrium.

“It’s complicated”: Exploring preferences in small-scale forest management in Austria using multi-objective optimization

This study combines survey data with multi-objective optimization to reveal that while Austrian small-scale private forest owners prioritize diverse economic and ecological goals, their actual management behavior is constrained by perceived complexity, suggesting that reducing this complexity is key to aligning their actions with their stated preferences for sustainable forest provision.

The carbon footprint of emergency care for low back pain in Sydney, Australia, 2016–2021

This study quantifies the carbon footprint of emergency department care for low back pain in Sydney, Australia, revealing that 15,736 presentations between 2016 and 2021 generated significant emissions primarily driven by patient travel and diagnostic imaging, with admitted patients contributing substantially more than those discharged home.

Raw material procurement in northwest Sierra Morena during the Middle Palaeolithic: quartz exploitation at La Sima Cave (Constantina, Seville, SW Spain)

This study characterizes Middle Palaeolithic lithic procurement at La Sima Cave in SW Spain through geological mapping and microscopic analysis, revealing that human groups employed a dual mobility strategy utilizing nearby quartz outcrops (<10 km) and more distant Guadalquivir River terraces (25–30 km) for higher-quality quartzite and chert.
