Differences in Dust Emission and Near‐Surface Transport Patterns Among Three Surface Substrate Types

ABSTRACT Soil wind erosion is a major driver of atmospheric dust emissions and land degradation. Many studies have examined dust release from different substrates, but differences in methods and units still limit quantitative understanding of how surface conditions and wind joint...

Application of Stable Isotopes in Water Transport Processes of the Soil–Plant–Atmosphere Continuum in Eucalyptus Plantations: A Review

The water cycle in forest ecosystems is a core component of ecosystem services, and it is crucial for revealing terrestrial hydrological processes and regulation mechanisms. Investigating water migration across interfaces of the soil–plant–atmosphere continuum (SPAC) has long bee...

Explainable XGBoost–SHAP Modeling Coupled with GeoDetector for Forest-Fire Occurrence Susceptibility and Future Climate Sensitivity in the Dabie Mountains

Forest-fire occurrence susceptibility prediction remains challenging in mountainous regions because fire occurrence is controlled by nonlinear interactions among climatic, vegetation, topographic, and anthropogenic factors. Developing interpretable prediction models that integrat...

Non-monotonic response of net dust deposition kinetics to low wind speeds

Abstract. Dry deposition is a major sink for mineral dust, yet its behavior under weak winds remains poorly constrained and is often parameterized monotonically with wind speed. Here we quantify size-resolved dust deposition kinetics in a large closed-circuit recirculating wind t...

Species-dependent effects of tool geometry and machining parameters on surface roughness during longitudinal up-milling of Mongolian Scots pine and white oak

Previous studies on wood milling have mainly examined individual species or restricted machining conditions, leaving uncertain whether responses to tool geometry and cutting parameters are transferable across anatomically contrasting woods. This study aimed to distinguish common...

Drought memory and vegetation shifts triggered by recurrent extreme drought events in alpine peatlands amplify the sensitivity of carbon sink function to drought

Climate change is expected to intensify the frequency and severity of extreme drought events, profoundly influencing terrestrial ecosystem carbon budgets. Peatlands are crucial carbon reservoirs in the global carbon cycle, storing nearly one-third of the world's soil carbon. Howe...

Declining Small-Stem Abundance and Contrasting Intraspecific Spatial Dynamics in a Tropical Montane Rainforest on Hainan Island, China

Dispersal limitation, habitat heterogeneity, and density-dependent processes shape tree distributions, but their spatial signatures can overlap with those of vegetative reproduction. We examined diameter structure and intraspecific spatial patterns of eight dominant species using...

Translocation and Allocation of Smooth Vetch‐Derived Nitrogen Along the Plant–Soil Continuum in Citrus Orchards

ABSTRACT The dynamics and distribution of legume‐derived nitrogen (N) throughout the phenological cycle in legume‐based agroforestry systems remain poorly understood, limiting our understanding of N allocation and use efficiency. Here, an in situ 15 N labeling approach was used t...

Synergistic mechanism between photosynthetic performance and growth of interspecific hybrid scions in Catalpa Scop

Abstract Background and objective Grafting is a pivotal technique for clonal propagation in Catalpa , yet the regulatory mechanism by which scion genetic background coordinates photosynthetic productivity and growth remains elusive. Methods Using two-year-old Catalpa ovata seedli...

Salinity constrains rhizosphere-driven soil carbon mineralization through shifts in microbial communities and enzyme activities

Functional assessment of how the rhizosphere regulates soil carbon (C) mineralization is critical for predicting ecosystem C dynamics under global climate change. However, the mechanisms by which rhizosphere-mediated microbial traits and extracellular enzyme activities influence...

Common-Garden Transcriptomes Distinguish Leaf-Form-Associated from Site-Associated Expression in Zygophyllum xanthoxylum

Zygophyllum xanthoxylum (Bunge) Maxim. is a dominant, deep-rooted shrub of the temperate deserts of north-western China whose leaflets range from comparatively flat and broad to slender and terete, but the molecular basis of this variation has rarely been reported. We compared th...

Profile-wide desalinization is associated with increased deep-soil microbial biomass and reduced iron-bound carbon in coastal wetland restoration

Tillage- and mulching-based interventions are increasingly used to control invasive plants and modify soil hydro-salinity, but their effects on subsoil carbon (C) stabilization are poorly quantified. We conducted an 18-month field experiment in a Spartina alterniflora–invaded est...

Genetic transformation of Pinus elliottii: Association of SPX3 with coordinated nitrogen-phosphorus metabolism and antioxidant defense

The lengthy breeding cycle of Pinus elliottii Engelm., an economically important conifer widely cultivated in southern China, and the inherently low transformation efficiency of conifers present major obstacles to genetic improvement. To address these challenges, an Agrobacterium...

Plant functional trait and plant–microbe network β-diversity dominate spatial turnover of ecosystem multifunctionality in subtropical forests

Intensified human activities and climate change are accelerating biodiversity loss and the degradation of ecosystem functions. While the positive role of local (α-scale) biodiversity in sustaining ecosystem multifunctionality is well established, its drivers at broader spatial (β...

Comparative Transcriptomics Reveals Divergent Expression Patterns Related to Carbon Metabolism, Transport, and Regulation in Juvenile Stems of Four Fagaceae Species

Background/Objectives: We compared juvenile whole-stem transcriptomes of Quercus glauca, Quercus acutissima, Quercus fabri, and Castanopsis sclerophylla to examine carbon metabolism and transport. Methods: Three seedlings per species were sampled in one session. RNA sequencing (R...

Taxonomic insights and preliminary enzyme assays of Rhytidhysteron species (Hysteriales, Hysteriaceae) from litter layer in the Yuan Jiang savanna, China

Six terrestrial hysteriaceous fungi were collected from litter in dry-hot valleys, China, all exhibiting the typical morphological characteristics of the genus Rhytidhysteron. Detailed morphological examimation combined with RAxML phylogenetic analysis of combined LSU, SSU, ITS,...

A Detailed Evaluation of the Suitability of Waterbird Habitats in Hangzhou Bay National Wetland Park—A Differential Analysis of Wading Birds and Swimming Birds

Hangzhou Bay is an estuarine ecosystem on the Yangtze River Delta and a key wintering habitat for waterbirds. However, suitable waterbird habitats have been degrading and fracturing. Therefore, we aimed to assess waterbird habitat suitability and identify the principal factors af...

Dual Roles of RAD23b and RAD4 on the Desiccation Tolerance of Germinated Seeds

Desiccation tolerance (DT) is a survival trait enabling orthodox seeds to withstand extremely low water content. While some protective factors are characterised, it remains mechanistically obscure. Here, based on PEG-induced DT re-establishment in germinated Brassica napus L. see...

Conditional cooling from large-scale urban afforestation: ecosystem functioning and planning implications

Large-scale urban afforestation is increasingly promoted as a Nature-Based Solution for reducing urban heat. Yet afforestation does not cool cities uniformly, and the conditions under which it delivers sustained thermal benefits remain poorly understood. This uncertainty limits t...

A Reference-Free K-mer Framework Enhances Genomic Prediction in Highly Heterozygous Woody Species: A Case Study in Litsea cubeba

Abstract Litsea cubeba, an economically important woody species in the Lauraceae, is widely cultivated for spice and essential oil production. Core agronomic traits, particularly fruit morphology and yield per plant, directly determine its commercial value. However, genetic impro...
