Planetary Energy Imbalance, ENSO Variability and Cryospheric Instability: A Multi-Scale Analysis of Himalayan Climate Risk and the 2026 Nepal Flood

This study employs a multi-scale analytical framework to demonstrate that the 2026 Nepal flood was not caused by a single factor like planetary energy imbalance or ENSO, but rather emerged from the complex interaction of long-term cryospheric warming, permafrost degradation, and short-term hydrometeorological triggers within a multi-hazard context.

Ecological Footprint of Road Congestion in Kolkata City: An Integrated Traffic, Carbon Emission and Spatial Assessment Framework

This study proposes and demonstrates the Ecological Footprint of Road Congestion (EFRC) framework, which quantifies the carbon and spatial impact of traffic congestion in Kolkata by integrating traffic, emission, and spatial data, while clarifying that the presented numerical results are derived from synthetic data to validate the methodology rather than to report actual field measurements.

A review of spatially explicit climate emulators as agile tools for decision-support

This review of 76 studies reveals that while spatially explicit climate emulators are emerging as agile decision-support tools, their effectiveness is currently hindered by a fragmented landscape, a lack of robust long-term validation, misalignment between development and application, and concerns over equitable access, necessitating clearer definitions and stronger cross-domain integration.

A modelling approach to identify habitat suitability for Indian squid (Uroteuthis (Photololigo) duvaucelii) in the northeastern Arabian Sea

This study utilizes a generalized additive model to identify key environmental factors—including sea surface temperature, salinity, chlorophyll-a, and current speed—that determine the habitat suitability and seasonal distribution of the Indian squid (*Uroteuthis duvaucelii*) in the northeastern Arabian Sea, thereby supporting sustainable fisheries management.

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.
