Spatiotemporally Adaptive Bilayer Silk Fibroin–Polyvinyl Alcohol–Metformin Composite Coating on Biodegradable Zinc for Orthopedic Applications

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Biodegradable zinc (Zn)‐based materials are considered promising candidates for orthopedic applications because of their favorable mechanical properties, controllable biodegradability, and good biosafety profiles. However, their clinical translation is limited by early‐stage corrosion‐induced cytotoxicity and inflammation, as well as ...

The vesicle trafficking R‐SNARE VAMP714 connects auxin responses, ROS and ion homeostasis in Arabidopsis under salt stress

open access: yesNew Phytologist, Volume 251, Issue 1, Page 207-227, July 2026.
Network of VAMP714‐dependent interactions during salt stress. Summary Plant responses to salt stress include an altered root architecture mediated by ion imbalances, reactive oxygen species (ROS) accumulation, and altered hormonal responses. Auxin is implicated in these processes.

3D Printed High‐Strength Hydrogel for Dual Release of Cu2+ and Ag+ Ions to Enhance Bone Repair and Antibacterial Properties

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.

不同植被覆盖度对紫色土坡面侵蚀过程的影响

open access: yesShuitu Baochi Xuebao, 2017
为研究植被覆盖度对紫色土坡面侵蚀过程的影响,探讨有效控制水土流失的坡面植被临界盖度问题,利用人工模拟降雨试验与室内分析相结合的方法对紫色土坡面侵蚀过程进行分析。结果表明:(1)总体上,紫色土坡面产流量随植被覆盖度的增大而减小,二者之间呈现线性负相关,但是植被覆盖度在25%以下,径流量变化不明显,植被覆盖度达75%时,径流量处于较低的稳定值,明显低于植被覆盖度0%,25%,50%;(2)坡面侵蚀泥沙量随植被覆盖度的增加而减少,二者呈现二次项相关(R2=0.99),植被覆盖度25%以下对坡面减沙起到重要作用,

Must the Shit Hit the Fan Before Anyone Responds? Response‐Activating Texts as Catalysts for Organisational Responsiveness

open access: yesRisk, Hazards &Crisis in Public Policy, Volume 17, Issue 2, June 2026.
ABSTRACT The article examines how ‘soft’ information functions in rational organisations that emphasise hard information, and how this affects safety. Drawing on fieldwork in a high‐security prison, we analyse how frontline personnel interpret soft information about potential disturbances. We identify three coexisting institutional logics shaping these

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

open access: yesFunctional Ecology, Volume 40, Issue 6, Page 1906-1920, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

红壤侵蚀退化坡面植被恢复过程中的水土保持效益演变

open access: yesShuitu Baochi Xuebao, 2022
为探究花岗岩红壤侵蚀退化坡面植草措施实施中植被在不同生长阶段水土保持效益的演变规律,设置条带型(D1)、随机型(D2)、斑块型(D3)3种不同植草格局坡面,并以侵蚀退化裸地坡面(CK)作为对照开展试验,在天然降雨条件下监测整个植被生长过程中的坡面土壤侵蚀变化特征。结果表明:(1)植被的生长可显著提升坡面的水土保持能力,随着植被生长阶段的推进,坡面的产流产沙量明显下降,减流效益达20.74%~79.03%,减沙效益达97.42%~99.40%,但在不同降雨类型下,随着植被生长 ...

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

A more‐than‐human political ecology of Indonesian songbird trade

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Since its inception, conservation science has considered wildlife trade a problem. In focusing on conservation outcomes, conservationists almost completely ignore the welfare of traded animals and plants and the harms they endure. We developed a political ecology approach that incorporates the interconnectedness of people with animals and ...

几种挺水植物净化生活污水总氮和总磷效果的研究

open access: yesShuitu Baochi Xuebao, 2004
研究了石菖蒲、灯心草和蝴蝶花3种不同植被系统、基质为河砂的潜流型人工湿地净化生活污水总氮和总磷的效果,并同无植被系统、相同基质的潜流型人工湿地净化效果进行了比较,结果表明:在较低浓度范围里无植被的人工湿地和3种有植被的人工湿地对污水中总氮有较好的去除作用,随着污水中总氮浓度的增加,虽然无植被的人工湿地和有植被的人工湿地去除总氮的效果均有下降的趋势,但有植被的人工湿地仍然能维持较高的总氮去除水平,无植被的人工湿地总氮去除效果则下降较快。在有植被的人工湿地中,以石菖蒲植被人工湿地氮素净化能力最强 ...
