This study applies a multi-taxon Community Dynamics Index to Korean stream biomonitoring data from 2011 to 2023, revealing that diatoms, macroinvertebrates, and fish exhibit significantly decoupled biological responses to environmental changes rather than synchronized ecosystem-wide reorganization.
This study utilizes generalized inversion of earthquake recordings from 16 seismic stations in southwestern Saudi Arabia to estimate frequency-dependent seismic attenuation and site amplification characteristics, providing critical data for improved seismic risk assessment and the design of earthquake-resistant infrastructure in the region.
This study integrates hydrogeochemical analysis, chemometric source apportionment, and health risk assessment across an urban-industrial corridor in India's Upper Gangetic Plain to reveal that intensive agricultural and industrial activities have shifted groundwater evolution toward salinization, creating severe non-carcinogenic health risks for children via drinking water while highlighting the need for targeted nutrient remediation and stricter groundwater security policies.
This study reveals that sewage treatment plant effluent acts as a persistent source of microplastic pollution in the Fuyang River, creating seasonal hotspots dominated by domestic fibers and PE/PP polymers while driving severe local ecological risks due to highly toxic PVC components, thereby necessitating urgent source control strategies for industrial polymers.
Twenty years after logging in Hyrcanian forests, adjacent stand canopy cover and tree species composition were found to be the primary drivers of soil and vegetation recovery on skid trails, with dense canopies and alder-mixed stands significantly accelerating physical and chemical restoration compared to open or pure-beech stands, though full recovery was not achieved without active intervention.
This study reveals that primary microplastics, particularly polyethylene and polyvinyl chloride, from a nearby petrochemical complex are the dominant source of sediment contamination in a Swedish coastal archipelago, with their spatial distribution shaped by particle density and local hydrodynamic conditions.
This study utilizes remote sensing data and Google Earth Engine to analyze hydro-climatic variability in the Tano River Basin from 2000 to 2024, revealing significant vegetation greening despite non-significant rainfall trends and establishing a robust framework for distinguishing spatial drought and extreme rainfall conditions to support adaptation planning.
By integrating satellite telemetry with three-dimensional oceanographic variables, this study reveals that sperm whales in the Azores exhibit strong site fidelity and foraging behavior driven by dynamic environmental factors, identifying the region as a critical, seasonally variable foraging hotspot requiring protection from anthropogenic threats.
This study optimizes acidified methanol extraction for archaeological lipid residue analysis by identifying that a 5% sulfuric acid concentration, a 1:5 solid-liquid ratio, and two extraction cycles maximize recovery efficiency, thereby establishing a robust and standardized protocol for analyzing real pottery samples.
This study assesses the distribution, anthropogenic sources, and ecological risks of eleven potentially toxic elements in the agricultural soils of southwest Punjab, India, revealing moderate contamination levels and higher cancer risks for children despite acceptable non-carcinogenic hazard indices.
