Hydrodynamic Identification of Potential Sediment Depositional Zones in the Lower Rabnabad Channel of Payra Port, Bangladesh

This study utilizes a calibrated MIKE21 FM hydrodynamic model to identify specific zones in the Lower Rabnabad Channel of Payra Port, Bangladesh, that are prone to sediment deposition due to subcritical and turbulent flow conditions, thereby providing critical data for future dredging operations and morphodynamic monitoring.

Climate-Driven Malaria Risk Among Children Under Five in Tanzania: Historical Associations, Future Projections, and Vulnerability Mapping

This study combines historical household data and future climate projections to demonstrate that rising temperatures are significantly driving malaria risk among Tanzanian children under five, revealing that under the SSP2-4.5 scenario, transmission suitability will expand by 2100 with the highest vulnerability concentrated in central and coastal regions where environmental risk converges with low household adaptive capacity.

Understanding warning chain failure in compounding urban climate hazards through an occupational security framework with comparative evidence from Pakistan and Canada

This paper argues that recurrent failures in urban climate warning chains, which turn forecastable hazards into mass casualty events in both Pakistan and Canada, are driven not by technical deficits but by ideological structures of neoliberalism, colonialism, and anthropocentrism, proposing an occupational security framework to guide people-centered, ecologically grounded preparedness.

Spatial Dynamics of Urban Expansion and Planning Disparities in the Islamabad–Rawalpindi Conurbation

This study utilizes remote sensing and spatial analysis to reveal that the Islamabad–Rawalpindi conurbation experienced a 101% increase in built-up land between 2011 and 2024, characterized by irregular growth phases, significant forest loss, and a stark disparity where the unplanned Rawalpindi District expanded nearly twice as fast as the planned capital, underscoring the urgent need for green-belt enforcement and conurbation-scale governance.

The onset of the Neanderthal world: Exploring ecological niche dynamics and technological variability across Marine Isotope Stages 12, 11 and 10

This study utilizes ecological niche modeling to demonstrate that while early Neanderthals significantly expanded their geographic ranges and ecological niches during the climatic amelioration of MIS 11 and 10 following MIS 12, their technological variability was driven by culturally adaptive flexibility in employing diverse lithic methods rather than direct responses to environmental suitability.

Aerosol hygroscopicity and photodegradation in the polluted Indo-Gangetic Plain compared with the clean Himalayas examined using a quartz crystal microbalance

This study utilizes a quartz crystal microbalance to demonstrate that PM2.5 aerosols in the clean Himalayas exhibit higher hygroscopicity and photolytic mass loss compared to the polluted Indo-Gangetic Plain, highlighting the critical influence of chemical composition and photochemistry on aerosol behavior.

Information needs across stages of volcanic activity for effective decision-making: A Ruapehu scenario, Aotearoa New Zealand

This study utilizes a hypothetical Ruapehu scenario to demonstrate that effective volcanic decision-making in Aotearoa New Zealand requires dynamic, stage-specific information strategies that evolve from preparedness during quiescence to impact management and recovery, necessitating tailored, actionable communication for diverse stakeholders.

Hierarchical drivers and ecological thresholds of shrub-to-forest transition in Mediterranean landscapes: implications for restoration

By analyzing 35 years of data across Catalonia using machine learning, this study reveals that shrub-to-forest transition in Mediterranean landscapes is a hierarchical process where landscape context (specifically surrounding forest cover) first determines propagule availability up to a critical threshold, after which local environmental conditions dictate establishment success.

Mycosporine-like amino acids in mangrove-associated red algae of the Maldives: a chemical and environmental baseline for the central Indian Ocean

This study establishes the first chemical and environmental baseline for mycosporine-like amino acids (MAAs) in Maldivian mangrove-associated red algae across 15 islands, identifying four known compounds and several unknown peaks to inform future conservation efforts as climate-induced canopy loss increases UV exposure.
