Tea Stewardship in Jingmai Mountain: A Practice‐Based and Cross‐Scalar Illustration of Ecological Citizenship in the Making

ABSTRACT The old tea forests of Jingmai Mountain in Yunnan, China, have been cultivated and maintained for centuries by indigenous Bulang and Dai communities through a unique ‘forest‐tea symbiosis’. We take this case as an entry point to examine a broader enquiry: how do a commun...

Multi-objective optimization and deep learning-based design of base-isolated structures with tuned inerter dampers under near-fault ground motions

Near-fault pulse-like ground motions (NPGMs) can significantly amplify the seismic response of base-isolated structures (BIS). Achieving optimal simultaneous control of both displacement and acceleration in BIS under varying ground motions remains a persistent challenge. This pap...

Photothermal catalytic conversion of nonanoic acid into bio-jet fuel-range alkanes

The substitution of petroleum-derived jet fuel with biomass-derived alternatives is a promising strategy to address the energy crisis and reduce fossil-resource dependence. However, the efficient conversion of biomass-derived feedstocks into bio-jet fuel-range alkanes remains cha...

Biochar–Microbe Interactions for Co-Remediation of Heavy Metals and Pesticides in Soils: Mechanisms, Synergies, and a Translational Framework

The co-occurrence of heavy metals (HM) and pesticides (PS) in agricultural soils poses a complex remediation challenge that resists single-amendment strategies. Although biochar (BC) has been widely reported as an efficient adsorbent for specific contaminants, increasing evidence...

The Algorithmic Well‐Being Paradox: When AI Decision Delegation Helps and Hurts Consumer Well‐Being

ABSTRACT As generative AI increasingly shapes consumer decision‐making, its implications for consumer well‐being remain unclear. Existing research largely focuses on the trade‐off between algorithmic efficiency and autonomy loss. This research advances understanding by proposing...

The Study on the Frequency Response Characteristics of Wood Orthotropy Based on Stress Wave Propagation Direction and Distance

This study investigates the frequency response of Zelkova schneideriana and Pinus sylvestris var. mongholica Litv. along longitudinal, radial, and tangential directions at different propagation distances. Sinusoidal signals from 20 to 200 kHz with 2 kHz intervals were applied usi...

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...

Spatial–Temporal Variability of PM2.5 and Ozone Pollution in the Huaihai Economic Zone of China

Fine particulate matter (PM2.5)and ozone (O3) compound pollution poses an important air-quality challenge in rapidly industrializing regions, and their relationships are affected by complex emission, chemical, and meteorological processes. This study investigates the long-term va...

Accumulation patterns of bioactive components in Morinda officinalis How across growth years

Harvesting time is a crucial factor affecting the quality of traditional Chinese medicine. Morinda officinalis How is a perennial herb with its root frequently used in both medicine and food industries. Iridoids, anthraquinones and saccharides are the main bioactive components of...

Characterizing the Variations of Total Column, Profile, and Surface Ozone in the Huaihai Economic Zone of China

The Huaihai Economic Zone (HEZ) of China is an important industrial region experiencing substantial surface ozone (O3) pollution. To characterize the long-term spatiotemporal and vertical variability of ozone over the HEZ, we integrated satellite-derived total column ozone (TCO),...

Unraveling the growth-promoting mechanisms of PGPR combined with organic fertilizer in bamboo shoots: Insights from rhizosphere microbial restructuring and metabolomic profiling

Excessive application of chemical fertilizers adversely affects soil health, while plant growth-promoting rhizobacteria (PGPR) have garnered increasing interest owing to their unique advantages. However, the mechanisms by which PGPR influence bamboo shoots growth remain poorly un...

Impacts of climate and land use changes on water retention in the transboundary Yuanjiang-Red River Basin: Historical attribution and future projections

Study region the Yuanjiang–Red River Basin (YRRB), Southeast Asia. Study focus Water retention (W R ) capacity in the transboundary YRRB has been increasingly affected by combined climate and land-use changes. However, limited quantitative attribution of historical drivers and un...

Species groups and identification key to Chinese Temnothorax ants (Hymenoptera, Formicidae) with descriptions of four new species from Shennongjia National Park

The myrmicine ant genus Temnothorax Mayr, 1861 is highly diverse in China; however, its fauna remained inadequately studied until recently. During the 2023 Background Resources Survey Project in Shennongjia National Park, four new species of this genus were discovered and are her...
