Climatic Niche Dynamics of Lantana camara from Its Native to Invasive Range: Implications for Invasion Risk in Nepal

This study reveals that *Lantana camara* exhibits high climatic niche stability between its native and invasive ranges in South/Southeast Asia, yet its current distribution in Nepal occupies only a fraction of the available suitable climate space, suggesting significant future invasion risk despite divergent model projections.

Labile organic carbon fractions and carbon-cycling microbial communities respond differently in rhizosphere and loosely root-associated soils along an alpine meadow degradation gradient on the Qinghai-Tibet Plateau

This study demonstrates that alpine meadow degradation on the Qinghai-Tibet Plateau differentially alters labile organic carbon pools and carbon-cycling microbial gene associations between rhizosphere and loosely root-associated soils, with soil physicochemical properties identified as the primary drivers of these variations.

Cradle-to-Cradle Environmental Assessment of Asphalt and Concrete Pavements under 100-Year Service-Life Scenarios in Australia

This Australian study employs a cradle-to-cradle life cycle assessment to demonstrate that asphalt pavements exhibit significantly lower environmental impacts than concrete over a 100-year service life, primarily due to the high carbon footprint of cement production in concrete, thereby supporting the selection of asphalt and improved recycling strategies for sustainable road infrastructure.

Transition between the Pacific and African mantle domains beneath southwest Pacific marginal basins

This study utilizes Sr-Nd-Pb-Hf isotopes from Cretaceous–Paleogene marginal basins in the southwest Pacific to demonstrate that the Zealandia continental subduction zone served as a critical boundary separating the subduction-enriched African mantle domain from the Pacific mantle domain, while hotspot-related samples further reveal distinct deep-mantle signatures consistent with this hemispherical dichotomy.

Agreement between Sentinel-1 C-band backscatter change and Sentinel-2 burn severity indices across land-cover types in a low-biomass transitional eco-region

This study demonstrates that integrating Sentinel-1 C-band SAR backscatter change with Sentinel-2 optical indices improves burn-severity assessment in the low-biomass, semi-arid Southern Great Plains, where traditional optical methods are limited by rapid vegetation recovery and soil background signals.

Atmospheric Heat Retention and Weakening Urban–Rural Thermal Contrast Driven by Surface Characteristics in the Indo-Gangetic Plains

This study analyzes two decades of data from seven Indo-Gangetic Plains cities to reveal that while daytime urban-rural temperature contrasts are narrowing due to rural moisture deficits, persistent nocturnal surface urban heat island effects are driven by built-up expansion and atmospheric retention, necessitating tailored diurnal and seasonal mitigation strategies.

Long-Term Monitoring of Cyclic Climate Variations to Assess Nutrient-Driven Chlorophyll-a (Chla) Dynamics in Highland Eutrophic Lake Erhai in China

This study analyzes 30 years of data from China's eutrophic Erhai Lake to demonstrate how cyclic climate variations, particularly rising temperatures and declining wind speeds, interact with nutrient enrichment to amplify chlorophyll-a concentrations and algal blooms, providing a scientific basis for sustainable water management and SDG 6.

Integrated Assessment of Heavy Metal Contamination in Water, Sediments, and Fish Along the Ravi River, Lahore: Pollution Indicators, Bioaccumulation, and Human Health Risks

This study evaluates heavy metal contamination in the Ravi River's water, sediments, and fish, revealing moderate to high cadmium levels and anthropogenic influence while concluding that human health risks from consuming local fish species remain within acceptable limits.
