Spatial Estimation of Near-surface Density From Gravity–topography Relationships Using Nettleton Analysis and a Moving-window Parasnis Approach

This study introduces a computationally efficient moving-window Parasnis approach that extends classical gravity–topography analysis to generate spatially distributed empirical density maps, enabling the identification of near-surface mass contrasts in both synthetic models and real-world data from northern Brazil.

Rituals on the move? Unusual dietary habits among non-local elite female “priestesses” at the Hallstatt period cemetery of Modřice, Czech Republic

Isotopic analysis of the Hallstatt period cemetery at Modřice reveals that lavishly buried, non-local elite female "priestesses" in a distinct burial district exhibited unusually low animal protein consumption, suggesting a deliberate, ritualistic dietary restriction potentially linked to their religious roles and origins in South-Eastern Pre-Alpine areas.

Impact of damming on water quality in tropical semiarid rivers

This study of eight Brazilian semiarid reservoirs reveals that while prolonged droughts drive short-term fluctuations, damming exerts only minor long-term net effects on most water quality parameters but significantly increases inorganic nitrogen, suspended solids, dissolved oxygen, turbidity, and chlorophyll-a due to preferential phosphorus retention and inadequate sanitation infrastructure, rather than functioning as effective treatment systems.

Distribution, Diversity and Abundance of Macrobenthic Fauna Along the South-Eastern Coast of Bangladesh: Seasonal Patterns and Environmental Drivers

This study characterizes the seasonal distribution, diversity, and abundance of macrobenthic fauna across three distinct habitats along the south-eastern coast of Bangladesh, revealing that dissolved oxygen, salinity, organic carbon, and silt content are the primary environmental drivers shaping community structure.

Section: Ecology, Behavior and Bionomics ​Effects of improved Mimosa caesalpiniifolia fallows and nutrient management on soil arthropod communities in subsequent upland rice cultivation in eastern Amazonia

This study in eastern Amazonia reveals that while six-year-old *Mimosa caesalpiniifolia* improved fallows significantly alter soil arthropod communities by reducing the abundance of surface Hymenoptera and Araneae compared to spontaneous secondary forests, subsequent nutrient management during rice cultivation has only weak effects on these invertebrate populations.

Climate induced migration due to Loss and Damage and trafficking vulnerability among haor communities in Northeastern Bangladesh

This study employs a mixed-methods approach in northeastern Bangladesh to demonstrate that climate-induced loss and damage, rather than pre-existing poverty, is the primary driver of displacement in haor communities, which subsequently precipitates a sharp rise in extreme poverty and significantly increases vulnerability to human trafficking through deceptive recruitment, debt bondage, and child marriage.

A critical review of frameworks, gaps and prospects for urban climate resilience research in the Global South

This study critiques the conceptual fragmentation and decision-orientation gaps in Global South urban climate resilience research through a PRISMA-guided review of 71 publications, identifying structural flaws like technocratic reductionism and the marginalization of local knowledge, while proposing a reconceptualized, ethically charged framework with specific governance levers and decision metrics to enable more actionable and equitable adaptive performance.

El Niño-Southern Oscillation, Indian Ocean Dipole, and Local Sea-Surface Temperature Forcing of Humid-Heat Extremes in the Arabian Peninsula

This study employs a Bayesian peaks-over-threshold framework to demonstrate that humid-heat extremes in the Arabian Peninsula are driven by a nonlinear combination of local sea-surface warming and remote climate variability, particularly La Niña events which can nearly quadruple the likelihood of dangerous wet-bulb temperature exceedances in populous coastal cities.
