Identifying socioeconomic and biophysical factors driving forest loss in protected areas
Conservation Biology, Volume 37, Issue 4, August 2023., 2023 Abstract Protected areas (PAs) are a commonly used strategy to confront forest conversion and biodiversity loss. Although determining drivers of forest loss is central to conservation success, understanding of them is limited by conventional modeling assumptions.

Avoiding and allowing apatite precipitation in oxygenic photolithotrophs
New Phytologist, Volume 238, Issue 5, Page 1801-1812, June 2023., 2023 Summary The essential elements Ca and P, taken up and used metabolically as Ca2+ and H2PO4−/HPO42− respectively, could precipitate as one or more of the insoluble forms calcium phosphate (mainly apatite) if the free ion concentrations and pH are high enough.

Journal of Ecology, Volume 110, Issue 1, Page 97-116, January 2022., 2022 In the BEF‐China experiment, metabolomics samples were collected from four different species and three organs (a). The metabolomes are species and organ specific (b), and the metabolome specificity is attributed to different chemical classes (c). Tree species diversity affects the metabolome composition (d), but more controlled interaction experiments ...

基于ATP-EMTP的配电线路避雷器防雷效果及保护范围仿真分析
Dianci bileiqi, 2020 由于10～35 kV配电线路的绝缘水平普遍较低,因此在我国配电线路雷电保护设计中经常采用氧化锌避雷器进行雷电防护。通过建立模型开展数值仿真计算,进行10 kV配电线路安装线路避雷器的雷电防护效果研究,分析不同避雷器类型、不同杆塔冲击接地电阻以及雷击位置等对避雷器防护效果的影响并并分析其保护范围。结果表明,加强线路绝缘、增加配电线路中的避雷器数量可显著提高整条配电线路的耐雷水平,是提高配电线路防雷效果的两个重要措施;雷击位置对线路耐雷水平的影响则与避雷器雷电保护范围密切相关,当雷击位置距离线路避雷器较远时,

Hybrid Flexible–Soft Neural Interface as a Practical Solution for Long‐Term Implants
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Implantable neural interfaces face persistent challenges in long‐term functionality due to chronic immune responses, mechanical mismatch with tissue, and material corrosion in vivo. The commonly used flexible materials, such as polyimide and parylene‐C (poly[monochloro‐p‐xylylene]), have advantages in low water vapor permeability and high ...

The underappreciated roles of fog and dew on vegetation and biocrusts
New 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 ...
