Physiological and Proteomic Analyses in Responses of Mangrove Plant Kandelia obovata Seedling Leaves to Submergence Stress [PDF]
, 2016 水淹是限制多数植物生长和发育的重要限制因子。红树植物是生活在滨海湿地的一类对水淹具有较高耐性的木本植物。近年来，在对红树林湿地的围垦和鱼塘养殖的开发过程中经常会造成对红树植物的严重水淹，甚至是长时间、整株植物的被淹（特别是对幼苗）。然而，红树植物对这种长时间、全淹胁迫的响应仍有待研究。在本研究中，基于蛋白质组学技术，我们采用红树植物秋茄（Kandeliaobovata）幼苗为实验材料，来探究红树植物秋茄耐受长时间、全淹胁迫的生理响应和分子机制。主要研究结果如下: （1）秋茄幼苗持续全淹处理 ...

Estimating the total mortality of seabirds following a marine heat wave
Conservation Biology, EarlyView.Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

Shuitu Baochi Xuebao, 2003 借鉴国内外研究基础,探讨了区域可持续土地利用管理评价指标设计的结构和原则,并且以农用土地为侧重点,系统提出区域可持续土地利用管理评价的指标体系框架.该框架以整个区域农用土地为对象,以土地质量指标为主体,构建了5个方面的评价标准,即土地质量维持或提高、土地资源的供应与当前及未来需求目标的平衡、非再生资源合理使用、土地资源的非生产功能得到兼顾、良好的社会政策环境支持.并分别建议了评价指标.

The Diagnosis of the Ancient Trees of Ficus microcarpa [PDF]
, 2010 通过对鼓浪屿古榕树的普查,选择其健康诊断的生长指标和生理指标,包括当年生枝叶、果实生长状况、叶绿素荧光等,对不同生长势的古榕树进行分析,旨在探讨基于生长指标与生理指标相结合的古榕树的健康诊断方法,为古榕树的养护与复壮提供依据。结果表明,生长指标与生理指标能较一致地指示古榕树的健康状况。因此,可通过生长指标与生理指标相结合的方法诊断古榕树的健康状况。Based on the general investigation and analysis of the ancient trees of Ficus ...

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.
