Parasitic Helminths (Trematoda, Nematoda, Cestoda) as Bioindicators of Heavy Metal Pollution in Marine Ecosystems: A Comparative Study on Saurida undosquamis

This study demonstrates that parasitic helminths (specifically Trematoda and Cestoda) isolated from the Brushtooth lizardfish (*Saurida undosquamis*) along the Misurata coast of Libya serve as sensitive and reliable bioindicators for monitoring heavy metal pollution, particularly showing higher accumulation of toxic metals like Cadmium and Lead during the cold season.

Urban Air Pollution as a Driver of Climate Forcing in Central and South Asia: Causal Evidence from Tashkent (Uzbekistan) and Lahore (Pakistan)

This study provides causal evidence that severe urban air pollution in Tashkent and Lahore significantly drives regional climate forcing, contributing approximately 18–23% of observed urban warming trends through aerosol–climate interactions that amplify temperature anomalies and smog formation.

The impact of urban wetland landscape patterns on runoff: A comparative study of three Chinese cities with frequent extreme rainfall

This study demonstrates that in three Chinese cities prone to extreme rainfall, specific wetland landscape patterns—such as cover, connectivity, and patch density—significantly influence the spatial variability of urban runoff beyond conventional environmental factors, highlighting the need to integrate landscape configuration into sponge city planning for enhanced flood resilience.

Contrasting Triggering and Maintenance Mechanisms of Two Squall Lines and Extreme Gale Causes under a Common Cold Vortex

This study utilizes multi-source observational and reanalysis data to elucidate how two squall lines, occurring under a common Northeast China Cold Vortex on June 13, 2022, exhibited distinct triggering mechanisms (synoptic-scale forcing versus topographic and frontogenetic effects), maintenance lifespans (sustained cold pool-shear balance versus rapid disruption), and extreme gale origins (large-scale cold pool pressure gradients versus localized bow echo and rear-inflow jet dynamics).

Matched Riverbank–Channel Elemental Profiles along the Tigris River: An Exploratory Compositional Survey

This exploratory study of 21 matched samples from seven Tigris River reaches found no statistically significant consistent geochemical differences between channel sediments and riverbank soils, suggesting that while local hydraulic sorting may occur, the current data provides only a baseline for future targeted monitoring rather than establishing definitive environmental risks.

Combined Inversion of Active and Passive Seismic Data Based on Optimized Data Selection

This paper presents a methodology for the combined inversion of active and passive seismic data using optimized passive event selection to maximize subsurface illumination and model resolution without introducing bias from heterogeneous data distribution, as demonstrated by successful application to the BedrettoLab rock laboratory in Switzerland.

Circular economy and decarbonization reshape appliance material demand and emissions in Europe

This study demonstrates that while circular economy strategies alone can significantly reduce material demand and emissions for European household appliances, achieving deep decarbonization by 2050 requires an integrated policy approach combining circularity, energy efficiency, and electricity-system decarbonization.

Indirect electrification enables the 2°C goal without reliance on carbon dioxide removal

This study demonstrates that achieving the 2°C goal without relying on carbon dioxide removal is feasible through indirect electrification, provided that the substantial technical challenges of rapidly scaling up renewables, electrolyzers, and demand-side electrification can be overcome, albeit at a cost increase of approximately 20%.

Facies-dependent response of reef–shoal development to orbital pacing in the Changxing Formation, Sichuan Basin

This study demonstrates that while identical orbital rhythms drove the Changxing Formation's reef–shoal development in the Sichuan Basin, the resulting stratigraphic architectures varied significantly between facies belts, with the intraplatform setting favoring sustained vertical aggradation and the platform-margin environment promoting repeated shoal expansion and retreat.
