Positive effect of long-term nutrient additions on litter decomposition depends on the stage coordination between litter quality and soil environment in a subtropical plantation

Long-term nitrogen and phosphorus additions in a subtropical Chinese fir plantation accelerate litter decomposition through a stage-dependent synergy where nitrogen primarily drives early-stage mass loss via increased soil availability and cellulose release, while phosphorus becomes the dominant driver in later stages.

Large-scale climate variability and marine heatwaves increase harmful algal bloom events along global coastlines

This study establishes a multiscale framework demonstrating that marine heatwaves drive a nonlinear increase in harmful algal blooms globally, a relationship that is significantly modulated by the background climatic conditions of ENSO phases and specific environmental factors like sea surface height and iron availability.

Pilot-scale evaluation of floating macrophytes for tertiary polishing of dairy wastewater: An integrated assessment ofCd and Pb removal mechanisms

This pilot-scale study demonstrates that floating macrophytes, particularly *Pontederia crassipes* and *Pistia stratiotes*, effectively serve as tertiary polishing systems for dairy wastewater by removing organic pollutants and accumulating cadmium and lead through mechanisms influenced by pH-driven metal speciation, thereby validating their potential for low-cost agro-industrial effluent treatment.

Heavy Metal Distribution and Ecological Risk Assessment of Agricultural Wetland Sediments Surrounding a Proposed Uranium Exploration Area in Tanzania

This study assessed heavy metal concentrations in agricultural wetland sediments surrounding a proposed uranium exploration area in Tanzania, finding generally low contamination levels and minimal ecological risk, thereby establishing a stable baseline for future environmental monitoring despite slight lead enrichment at one site.

Bayesian Gaussian Process Modeling of Nonstationary Climate Extremes with Unknown Physical Drivers: A GP-GEV Framework for West African Rainfall

This study introduces a Bayesian Gaussian Process–Generalized Extreme Value (GP–GEV) framework that models nonstationary West African rainfall extremes using latent processes instead of uncertain physical covariates, demonstrating superior predictive accuracy and uncertainty calibration compared to traditional stationary and parametric-trend models.

Effect of Refugee Migration on Land Use Land Cover and Its Effect on Forest Resources: A Case Study of Borno State, Nigeria

This study utilizes multi-temporal satellite remote sensing via Google Earth Engine to demonstrate that insurgency-driven displacement in Borno State, Nigeria, has caused region-specific, persistent vegetation degradation and a shift from natural woodland to low-density farmland, evidenced by declining vegetation indices between 2013 and 2021.

Vernacular Passive Cooling Strategies in Tropical and Arid Climates: A Comparative Systematic Review

This systematic review analyzes 50 studies to demonstrate that vernacular passive cooling strategies from hot-arid and tropical climates are not mutually exclusive but offer transferable, adaptable solutions—such as the effective use of thermal mass in the tropics and mashrabiya-inspired shading—that can inform sustainable, climate-resilient architecture beyond their traditional geographic confines.

Pollinator decline reveals uneven impacts of climate-driven biodiversity loss

This study demonstrates that climate-driven pollinator decline will cause significant, spatially concentrated economic losses across the EU by 2070, revealing that standard national-scale assessments systematically underestimate these risks by masking severe regional disparities and sectoral vulnerabilities.

Air Quality and Economic Trade-Offs of Relaxing California’s Gasoline Volatility Limits

This study finds that relaxing California's stringent summer gasoline volatility limits would yield significant monthly production and consumer cost savings exceeding the monetized health impacts, despite causing a negligible increase in ozone levels due to the lower reactivity of winter-blend emissions.

From Wild Foods to Mixed Subsistence: Nonlinear Nutrition Transition among Hadzabe Foragers

This study challenges the linear model of nutrition transition by demonstrating that Hadzabe foragers have undergone a nonlinear dietary shift characterized by the simultaneous expansion of both wild and market-based food consumption, driven by complex social-ecological reconfigurations rather than simple substitution.
