Journal of Linguistic Anthropology, Volume 35, Issue 2, August 2025.Abstract This article argues that social actors' media ideologies about digital interfaces are key to the enregisterment of online activities. Focusing on an online register emergent from user activities around Year, Hare, Affair (YHA)—a state‐aligned Chinese animation—I explore how different metadiscourses evaluate this register by entextualizing ...

People and Nature, Volume 7, Issue 7, Page 1749-1768, July 2025.Abstract Social‐ecological systems (SES) are coupled systems formed by the intricate interactions between humans and nature. Our movement towards sustainable lifestyles requires a robust understanding of these interactions. Achieving a sustainable win‐win situation for both social and ecological systems, therefore, necessitates a sound scientific ...

Functional Ecology, Volume 39, Issue 6, Page 1550-1566, June 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Forests store substantial amounts of soil organic carbon (SOC), but SOC stocks differ strongly between forest ecosystems dominated by arbuscular mycorrhizal (AM) or ectomycorrhizal (EcM) fungi.

Shuitu Baochi Xuebao, 2019 以江西省鹰潭市的典型旱地、稻田和林地为研究对象，采用野外亮蓝染色示踪试验结合室内图像处理的方法，量化了各样地土壤剖面染色特征参数，明确了水流类型的剖面分布规律，并揭示了土壤理化性质对水流特征的影响机制。结果表明：染色面积比（SAR）随着土层深度的增加急剧降低，0-60 cm土层的平均SAR表现为稻田（28.16%）高于旱地（21.95%）和林地（18.64%），SAR差异主要体现在5-25 cm土层；染色路径数（SPN）随着土层深度的增加先增加后减小，整个剖面的平均SPN为稻田最多（20条），旱地其次 ...

Conservation Biology, Volume 39, Issue 3, June 2025.Abstract Globally, Indigenous peoples and local communities (IPs and LCs) are fighting for the recognition of their knowledge and decision‐making authority in freshwater conservation. In the Amazon, decision‐making around freshwater management and conservation has often overlooked Indigenous and local knowledge (ILK) and the connections between ...

Shuitu Baochi Xuebao, 2011 通过盆栽试验研究土壤菌对喷播基质物理性质及抗冲抗剪性能的影响。结果表明:土壤菌与黑麦草出苗率及盖度、容重、抗冲性、抗剪性4种基质效应指标之间存在着显著的相互作用关系。土壤菌的应用,明显增加土壤微生物量,基质结构基得到明显改善(基质容重降低了0.10 g/cm3),喷播植物的出苗率和盖度分别增加了55%和0.21,喷播基质抗冲抗剪能力得到改善,这既有微生物菌种对基质物理结构的改善作用,也有促进植物生长和覆盖对地表的保护作用。

Functional Ecology, Volume 39, Issue 4, Page 1096-1111, April 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Many invasive plant species have demonstrated a better ability to tolerate and accumulate heavy metals than their co‐occurring native plants. Given the potential biological toxicity of heavy metals to phytopathogens, we postulated that heavy metal contamination could ...
