Microfluidic-based high-throughput isolation enhances the recovery of novel strains and diversity from Arctic soil microbiome

ABSTRACT Microbial cultivation remains essential for understanding the physiology, ecology, and biotechnological potential of environmental microbes, yet conventional plate-based methods (CPM) recover only a minute fraction of the environmental microbiome. Polar regions, particul...

Drought amplifies the impact of vegetation phenology on wildfire in Guizhou Province, China

Vegetation phenology is highly sensitive to climate change and may influence wildfire by regulating fuel accumulation and fuel moisture. However, under increasingly frequent extreme droughts, clear evidence is still lacking regarding how phenological changes affect wildfires acro...

Evaluation of Ferromanganese Crusts on Western Pacific Seamounts Using a Distance–Relative Water Depth Variogram Model Based on Multiseamount Data

High survey costs restrict geological stations to an extremely sparse distribution, which has constrained the establishment of geostatistical models of ferromanganese crust thickness on individual seamounts. Moreover, because crust thickness is independent of direction yet contro...

Global-Scale Diagnoses of Tropical Cyclone Maximum Wave Heights from 5 Km GPM Retrievals and Their Implications for Reanalysis Bias

Tropical cyclone (TC) inner-core maximum wave height (MWH) measurements are virtually absent, forcing reliance on reanalyses such as ERA5. Using a GPM-retrieved dynamic MWH product on a 5 km pixel grid, 165 global TC–GPM overpass cases of tropical-storm intensity and above, drawn...

Contrasting rice-dryland crop rotation regimes drive divergent greenhouse gas emissions via labile organic carbon modulation, with trade-offs for crop yield

Context Optimizing crop rotations is essential for synergistically increasing yield and reducing environmental impacts. However, in rice-dryland crop rotation systems, the underlying mechanisms through which different dry-season crops influence subsequent rice yield and greenhous...

Bacterial Diversity and Community Assembly in Deep-Sea Sediments: Observations from the Philippine Sea

Microorganisms are important components of marine ecosystems and are widely distributed across global marine sediments. Although studies on microbial communities in deep-sea sediments have been increasing worldwide, research in the Philippine Sea is still at an early stage. In th...

Spatiotemporal Characteristics of Carbon Source–Sink Dynamics in the Coastal Waters of the South Yellow Sea, China

Continental-shelf marginal seas play a pivotal role in the global carbon cycle. The coastal South Yellow Sea (SYS), located in an intense land–ocean interaction zone, is a key region for coastal carbon cycle research. The issue addressed in this region is that strong land–sea int...

Empirical Post-Generation Correctness Assessment for Natural-Language Access to Urban PostGIS Databases

Natural-language interfaces make urban spatial databases accessible, but generated structured query language (SQL) can execute successfully while returning a semantically incorrect answer. We evaluate a post-generation correctness-ranking layer on 18,900 candidates from Nanjing,...

Earth Observation of Ecological Restoration Effectiveness and Ecosystem Functional Recovery in the South China Karst: From Greenness Monitoring to Functional Verification

Long-term Earth observation has reliably documented vegetation greening, biomass increases, and the mitigation of rocky desertification across the South China karst. However, “greening” alone neither demonstrates an incremental effect of ecological restoration interventions nor s...

Service Scale and Level: How Origin–Destination Interactions Shape Intercity Travel Flows Within Mega-City Regions

As regional integration and high-speed transport networks advance, intercity travel flows within mega-city regions (MCRs) provide a lens for understanding regional functional division of labor and spatial organization. Concentrated high-intensity flows between core cities and maj...

Topographic and economic drivers of agricultural–ecological coupling in Gansu Province: spatial differentiation and threshold effects

Improved understanding of agricultural–ecological coupling is critical for sustainable development in semi-arid regions. This study integrated the Remote Sensing Ecological Index (RSEI), Agricultural Green Development Index (AGDI), Coupling Coordination Degree (CCD) model, and XG...

Exploring the potential of large language models for public participation in urban redevelopment planning

Public participation is essential to human-centered urban planning, yet existing approaches often struggle to translate dispersed public opinions into clear and discussable preference expressions. This limits substantive deliberation between public preferences and expert knowledg...

Aridity drives carbon redistribution among biomass, soil organic and inorganic pools following forestation

Forestation is widely promoted as a nature-based solution for climate change mitigation through carbon sequestration, yet its net carbon outcomes remain uncertain because water limitation may regulate both total carbon storage and carbon allocation among ecosystem pools. Here, we...

Humic acid urea boosts cotton yield and fiber quality with net life-cycle carbon benefits despite higher production-stage burdens

To systematically evaluate the effects of applying humic acid urea (HAU) in cotton fields and its associated environmental impacts, this study used the ReCiPe method to assess the environmental burden of HAU at the production stage, conducted field experiments to investigate its...

Drimane-Pyrone-Type Meroterpenoids and Co-Isolated Compounds from the Deep-Sea Fungus Penicillium rubens MABC05 and Their Anti-Ferroptotic and Cytotoxic Activities

Ferroptosis is a critical driver of tubular necrosis, and its effective inhibition holds significant potential for mitigating renal injury. In this study, chemical investigation of the strain Penicillium rubens MABC05 yielded nine drimane-pyrone-type meroterpenoids (1–9), includi...

Global Potential Refugia and Conservation Gaps for Threatened Marine Rays Under Future Climate Change

Climate change is redistributing marine biodiversity and may reduce the long-term effectiveness of static conservation networks. Threatened marine rays may be particularly vulnerable because many species have slow life histories, limited recovery capacity, and strong dependence o...

Poleward Redistribution of Tropical Cyclone Hazards over East Asia

Abstract Tropical cyclones (TCs) in the western North Pacific have undergone notable changes over recent decades alongside ocean warming and large-scale atmospheric circulation variability. Using TC best-track data from 1980 to 2025, we identify a pronounced poleward redistributi...

Hydrochemical Characteristics and Potential Health Risk Assessments of Groundwater Resources in the Yinchuan Plain, China

Groundwater quality is a critical factor constraining the sustainable and healthy development of the economy, particularly in regions with scarce water resources. Given the combined influences of natural processes and human activities, understanding the hydrochemical evolution an...

Geological Records of a 1000-Yr-Old Extreme Tsunami Event Revealed by Drill Cores in Qiongzhou Strait

In AD 1076, a super tsunami hit the South China Sea islands and the coasts of Guangdong and Vietnam. However, the impact on Hainan Island, situated farther from the tsunami source, remains unclear. Tsunami modeling indicates that seismic tsunamis from megathrust earthquakes in th...

Study on the Differentiation of Microbial Communities Under Different Soil Types in the Typical Black Soil Area of Songnen Plain

Soil type imposes multilayered environmental filtering via physical structure, chemical properties, and resource availability, shaping microbial community assembly. Using 70 samples (black soil n = 27, meadow soil n = 32, and brown soil n = 11) from a typical black soil region of...
