Diurnal Tidal Currents in the Gulf of Tonkin and the Qiongzhou Strait: Regime Characterization with Implications for Navigation and Tidal-Stream Energy

This study characterizes the Gulf of Tonkin's strongly diurnal tidal regime and surface kinetic energy by integrating multi-source data to map spatial variability, explain the significant gap between theoretical and realized power density through standing-wave dynamics, and identify the Qiongzhou Strait as the sole location meeting tidal-stream energy thresholds while highlighting the regime's impact on navigation.

Predictive ecological niche models using Open Access-‘BIG DATA’ quantify anthropogenic influence: Overlapping common (Panthera pardus), snow leopard (P. uncia) and prey species in Central Himalaya

Using open-access big data and machine learning ensembles, this study quantifies the anthropogenic impacts on habitat suitability and niche overlap between common leopards, snow leopards, and their prey in Nepal's Gaurishankar Conservation Area, revealing significant human-induced spatial overlaps that inform targeted global conservation strategies.

Source-resolved PM2.5 composition and oxidative potential in a petrochemical–steel industrial region using DTT and MTT assays

This study reveals that in a petrochemical–steel industrial region, PM2.5 oxidative potential is driven by distinct source-specific mechanisms, with petrochemical combustion primarily influencing cellular responses (MTT-OP) through organic-rich emissions, while coke/steel combustion dominates chemical activity (QDTT-OP) via metal-rich emissions.

Mechanism-Based Reconstruction of Coastal Blue Carbon Enhancement Potential Along the Land-Ocean Aquatic Continuums

This study introduces a mechanism-based framework that integrates upstream anthropogenic pressures and habitat responses to map coastal blue carbon enhancement potential in the Greater Bay Area, revealing that targeted restoration in specific "Robust Priority" zones driven by community-specific pressure responses can maximize carbon gains while accounting for land-ocean linkages.

Metabolomic signatures of functional recovery during petroleum bioremediation in a Niger Delta farmland

This study demonstrates that integrated LC-MS and ¹H-NMR metabolomics effectively track the functional recovery of petroleum-contaminated Niger Delta farmland by revealing distinct metabolic reorganizations, such as increased amino acid and central carbon metabolism, that accompany successful bioremediation beyond simple contaminant reduction.

Complex trade-offs across co-designed narratives of Australian land-system futures

This study translates four co-designed Australian land-use narratives into a national optimization model to explicitly reveal the complex trade-offs between biodiversity, carbon, food production, and economic returns, demonstrating that while a "Landscape Stewardship" scenario maximizes ecological benefits, a "Regional Ag Capitals" scenario prioritizes food output at the cost of climate goals.

Rethinking Climate Exposure through Gender, Vulnerability, and Adaptation Pathways in Smallholder Rice Farming in Nigeria

This study of 364 rice farmers in Nigeria reveals that while male and female farmers face similar climate exposure, women experience significantly higher vulnerability due to systemic inequalities in access to resources and support, necessitating gender-responsive adaptation strategies.

Habitat Structural Complexity Mediates Coral Reef Resilience and Biodiversity Loss Across Anthropogenic Disturbance Gradients

This study demonstrates that habitat structural complexity acts as a critical ecological buffer that enhances coral reef resilience and biodiversity, thereby mitigating the compounded negative impacts of local anthropogenic stressors and climate change.

Approximation of muddiness in troposphere by Multi-Angle Imaging Spectroradiometer (MISR)

This study utilizes Multi-Angle Imaging Spectroradiometer (MISR) data to analyze the three-dimensional distribution and seasonal persistence of atmospheric turbidity in Iran, revealing that the country's average aerosol load is significantly lower than the global average with distinct regional and seasonal variations.

Fingerprints of Holocene climate on the functional trait diversity of Arctic marine biota

By analyzing an 8,300-year marine sedimentary ancient DNA record from the high Arctic, this study reveals how Holocene climate variability and the Arctic Oscillation drove heterogeneous functional trait diversity and temperature-size trade-offs in marine biota, offering unprecedented insights into ecosystem resilience across millennial timescales.
