Optimizing biodiversity offsetting for habitat succession and colonization dynamics
Conservation Biology, EarlyView.Abstract Biodiversity offsetting aims to compensate for ecological losses from development through conservation and restoration. However, its long‐term outcomes under repeated impact–offset cycles remain uncertain. Using a conceptual forest succession model, we evaluated how offset outcomes are affected by interactions among compensation scale ...

, 2003 塔里木河是我国最长的内陆河，分布在塔里木河流域的天然植被，作为生物生态系统中的重要组分，在抑制荒漠化过程和保护生物多样性等方面有着重要的生态意义。本文结合塔里木河下游生态输水工程，运用当前生态学理论与相关的数理统计方法，采用地下水位动态变化与地表植物样方调查相结合，面上考察与定位、定时观测相结合，定性描述与定量分析相结合，个例分析与综合诊断相结合的方法，以塔里木河下游生态退化过程为研究主题，以反映塔里木河下游生态系统健康的主导环境因子一自然植被为主线，分析了塔里木河下游植物的生态位特征、植被的退化过程 ...

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.

, 2004 通过试验，科学的论证了只有培肥地力来改善土壤养分贮存库，才能促进荒漠绿洲农田生态系统的主要功能-良性养分循环。(1)建议干旱区应以水利和地力建设为中心，通过人为调控绿洲农田生态系统水分和养分的良性循环；(2)有关植物-碱化土壤生态系统养分循环方面的系统总结；(3)扩大林草面积增加绿色植被覆盖度，可以收到改变绿洲农田小气候和生物改良盐碱土等中低产土的效果。同时草业发展了可以保证农区畜牧业发展，使山区天然草场休养生息，得以自然恢复，使新疆干旱区山区“湿岛”涵养水源效应增强，协调好山盆关系 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Multilingual students in Anglophone universities often operate in survival mode. While translanguaging supports learning, critical gaps remain in understanding how translanguaging pedagogies transform and sustain motivation in English‐dominant contexts.

, 2006 以生态恢复和环境保护为根本目的的塔里木河下游生态输水工程已经实施了近6年,其间近20.0×108m3生态水已成功输送到塔里木河下游，许多研究表明，塔里木河下游生态环境出现了许多积极的响应和变化。如何用可持续发展的观点认识和实现生态过程与经济过程的和谐统一具有重要的科学研究意义。本文以塔里木河下游生态输水工程为依托，以生态输水后塔里木河下游的生态变化为主要研究内容，以输水过程中的地下水变化－地表生态变化－以及因生态变化而表现出的响应效应的生态经济价值为研究的主线，探讨了塔里木河下游输水后地下水 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT In English medium instruction (EMI), students face cognitive and emotional demands in second language (L2) communication, which may hamper their motivation and willingness to communicate (WTC). Adopting a mixed‐methods design, this study explores how growth mindsets affected student motivation (e.g., ideal L2 self and ideal disciplinary self ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT While English‐medium instruction (EMI) and English for Academic Purposes (EAP) courses are designed to promote language and content learning, their prevailing English‐only approaches often undermine students’ learning motivation. Against this backdrop, translanguaging has gained recognition as an effective pedagogical practice to support ...
