Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, EarlyView.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

A Systematic Scoping Review of Self‐Regulated Learning With AI in Language Education
International Journal of Applied Linguistics, EarlyView.ABSTRACT The rapid development of artificial intelligence (AI) technology has brought new opportunities for second/foreign language (L2) education while also raising concerns about the use of AI tools. This systematic scoping review provides a snapshot of the current state of research situated at the intersection of self‐regulated learning (SRL) and AI

International Journal of Applied Linguistics, EarlyView.ABSTRACT Although the use of AI technologies (e.g., chatbots and automated writing evaluations (AWE)) has gained considerable attention in language learning fields in recent years, how AI technologies have been designed and implemented in language learning education, as well as their effectiveness, is understudied.

Profiling Metacognitive Knowledge and Growth Mindset in EFL Vocabulary Learning
International Journal of Applied Linguistics, EarlyView.ABSTRACT Guided by the self‐regulated learning (SRL) framework, the present study investigates the associations between metacognitive knowledge and growth mindset in EFL (English as a Foreign Language) vocabulary learning, addressing a critical gap in the literature. While metacognitive knowledge, comprising person, task, and strategy dimensions, plays

野生动物学报, 2020 2018年8月—2019年1月，在四川省汶川县核桃坪野化培训基地，通过闭路电视监控系统，利用焦点动物取样法观察并记录了大熊猫（Ailuropoda melanoleuca）行为。基于以“姿势—动作—环境”（posture-act-environment，PAE）为轴心，以行为生态功能为依据的PAE编码系统，对育幼期大熊猫的行为进行分类和系统编码并构建PAE行为谱。分辨并记录了育幼期大熊猫及幼体姿势10种，动作49种，环境变量8种。记录到的行为可分为摄食、排遗、育幼、休息、运动和其他行为。基于PAE行为谱，

Researching on nitrite-oxidizing bacteria communities from the Pearl River estuary to the South China Sea basin [PDF]
, 1900 氮元素的生物地球化学循环几乎完全依赖于海洋生态系统中丰富的微生物调节。硝化作用（包括氨氧化过程和亚硝酸盐氧化过程）就是一个由微生物所介导的氧化反应，分别由氨氧化细菌、古菌（ammonia-oxidizingbacteria，AOB；ammonia-oxidizingarchaea，AOA）和亚硝酸盐氧化细菌（nitrite-oxidizingbacteria，NOB）介导。长期以来氨氧化作用一直被视为硝化作用的限速步骤，因此，亚硝酸盐氧化过程一直被人们所忽略。直到最近，在对纳米比亚氧最小层 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT This computational linguistic study analyzes 8743 Rednote posts to examine how sentiment, emotion, and content domain collectively shape social comparison dynamics on social media. We identify four key findings: (1) an emotional gradient, where upward comparison content exhibits the highest sentiment scores and downward comparison the lowest; (

Survey of viral diversity in the sediments of South China Sea [PDF]
, 2016 病毒是海洋生态系统中丰度最大，多样性最为丰富的微生物颗粒。海洋沉积物中的病毒丰度相比较海水中，要高1~2个数量级，并且其形态和基因型也更加多样。目前，人们对海洋沉积物中的病毒相关研究还比较少。为了增强对海洋沉积物中病毒的了解，本论文利用荧光显微镜法获得了珠江口沉积物以及南海北部和西部沉积物中病毒的丰度数据，并且通过病毒标记基因（g23&psbA）PCR扩增、克隆文库测序等分子技术获得了沉积物中T4类噬菌体和噬藻体类群的多样性信息。主要的研究结果： （1）荧光显微镜检测结果显示珠江口沉积物中病毒（4.49×

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.
