Organ‐specific ozone and nitrogen legacies strengthen substrate control over litter decomposition

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Elevated tropospheric ozone (O3) and nitrogen (N) deposition are concurrent atmospheric changes that strongly influence terrestrial carbon cycling, yet their combined effects on below‐ground decomposition remain poorly understood.

Conservative roots confer a larger microbial carbon pump efficacy than acquisitive roots by regulating microbial life‐history strategy

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root activity creates unique microbial hotspots in the rhizosphere by influencing the metabolic activities of surrounding soil microorganisms, profoundly regulating the dynamics of soil organic carbon (SOC). However, how root economic strategies affect the formation and

Influence of Alkaline Earth Barium on the Microstructure, Corrosion Behavior, and Cytocompatibility of Biodegradable Zinc

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Biodegradable Zn‐based alloys are promising candidates for temporary implants, yet excessive Zn2+ release during degradation may induce cytotoxicity and adverse tissue responses. In this study, Zn‐xBa alloys (x = 0.1 wt%, 0.5 wt%, 1.0 wt% and 3.0 wt%) were developed to achieve controlled corrosion behaviors with improved biocompatibility.

急水溪中上游的構造地形:以地形面與地形指標探討 [PDF]

open access: yes, 2011
[[abstract]]地形為地表的形態,由構造作用和外營力共同造成,在構造地形的研究中,對於地表的形態特徵常用地形面的比對與地形指標的計測說明,並進而推論活動構造的位置與活動性。在臺灣,過去的研究者多利用地形指標說明大範圍地區的活動構造的特性,對於小範圍活動構造的適用性研究較少,且較少結合地形面的比對。因此本研究在構造活躍的地區,選擇一研究區進行地形面對比與地形指標計測,以瞭解該區地形面、地形指標與活動構造的分布與活動性的關係,並推論對地形演育的影響。 本研究對比與調查急水溪中上游的地形面 ...

The underappreciated roles of fog and dew on vegetation and biocrusts

open access: yesNew Phytologist, Volume 251, Issue 1, Page 46-63, July 2026.
Summary Fog and dew represent minor components of ecosystem water budgets in most ecosystems. However, fog and dew can play an essential role in ecosystem dynamics and are particularly important for water‐limited systems. In addition to serving as direct water inputs, fog and dew can influence microclimate and water redistribution, thereby promoting ...

北方低温仿自然湿地脱氮除磷强化净化技术应用

open access: yesGongye shui chuli, 2023
为强化湿地系统的脱氮除磷效果,构建具有“预处理区+主处理区+后处理区”的多生境仿自然湿地系统,辅以底质调节缓释除磷措施,形成良好的厌氧/缺氧/好氧微生环境,同时为提升湿地系统的冬季运行效果,项目对湿地系统的填料床结构、菌群/植物配置以及低温运行模式进行了优化。结果表明,多生境仿自然系统湿地系统内部能够形成良好的厌氧/缺氧/好氧交替的微生环境,通过辅助添加土壤/生石灰缓释除磷填料,可进一步提高系统的除磷效果;通过采取填料床表层保温材料覆盖、低温冰下低水位运行技术措施,能够将冰下温度控制在2~3 ...

Symbiotic Germination Technique of an Endangered Epiphytic Orchid Dendrobium sinominutiflorum: A Promising Conservation Application 濒危附生兰科植物勐海石斛 (Dendrobium sinominutiflorum) 的共生萌发技术:一种具有应用前景的保护策略

open access: yesIntegrative Conservation, Volume 5, Issue 2, Page 192-204, June 2026.
We developed an effective ex‐situ conservation approach for an endangered orchid species, Dendrobium sinominutiflorum. A compatible fungal strain Tulasnella sp. was obtained by using in‐situ seed baiting technique. The Symbiotic germination with Tulasnella sp. significantly promotes seed germination and seedling growth.

Microstructure Characteristics and Strength–Ductility Mechanisms of a Novel Neutron Shielding Al‐6Mg‐5Gd Alloy Fabricated by Laser Powder Bed Fusion

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Al‐based neutron shielding materials suffer from poor laser powder bed fusion (LPBF) processibility, hindering their simultaneous achievement of good printability and exceptional mechanical properties. In this work, the newly developed rare‐earth Al alloy (i.e., Al‐6Mg‐5Gd) was processed by LPBF technique to meet the printability, mechanical ...
