Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...

Conservation Biology, EarlyView.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

Shuitu Baochi Xuebao, 2007 以长期定位试验点的紫色水稻土为研究对象，研究了耕作制度对紫色水稻土活性有机质和碳库管理指数的影响。结果表明：稻田长期垄作免耕0～10cm土层有机质含量比常规平作高，10～60cm土层有机质含量则比常规平作低；表明稻田长期垄作免耕土壤有机质具有表层富集现象；水旱轮作各土层有机质含量均比常规平作低。垄作免耕各土层活性有机质含量普遍增加，水旱轮作表层（0～10cm）活性有机质含量减少，其余土层变化不大。对活性有机质组分含量的研究表明：与常规平作相比，垄作免耕增加了土壤表层活性有机质各个组分的含量 ...

How Do I Measure up? Social Influence and L2 Motivation in the Algorithmic Age
International Journal of Applied Linguistics, EarlyView.ABSTRACT Comparative thinking is a fundamental human drive and a hallmark of contemporary life. For social action, such as the learning and use of additional languages, a target for appraisal (an L2 attribute) is evaluated in relation to a comparison standard (an appraiser's standpoint).

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study
International Journal of Applied Linguistics, EarlyView.ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.

International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines how foreign language teachers’ beliefs about the medium of instruction and translanguaging evolve over time by revisiting three in‐service teachers twelve years after their initial interviews. Using a qualitative longitudinal design, the study traces how translanguaging was initially framed as pedagogically deficient but ...

Microstructure and spectral analysis of Mytilus coruscus shell(厚壳贻贝贝壳的微结构及光谱分析)
Zhejiang Daxue xuebao. Lixue ban, 2015 贝类的贝壳是一种由碳酸钙晶体和有机质组成的高度有序的天然纳米复合材料，历来是生物材料和组织工程研究的重点对象.利用扫描电子显微镜、傅里叶红外光谱分析以及X射线衍射分析等，对厚壳贻贝（Mytiluscoruscus）贝壳的微观结构、碳酸钙晶体构型以及有机质结构特征进行分析.厚壳贻贝贝壳主要包含珍珠质层、肌棱柱层和斜棱柱层；不同层次的结构在外形、碳酸晶体构型、有机质分布等方面具有不同的特征.在后闭壳肌-贝壳连接部位，肌肉与贝壳碳酸钙晶体之间由一层有机质膜连接，且该膜质地明显有别于珍珠质层表面的膜 ...
