Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon
Conservation Biology, EarlyView.Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...

生长激素缺乏症与特发性矮身材儿童血清IGF-1及25-(OH)D水平变化的研究
Zhongguo shiyan zhenduanxue, 2020 生长发育迟缓发病率在6%-8%之间[1],临床表现为身材矮小、代谢紊乱及器官功能异常,其中身高为生长发育衡量最明显的指标,而生长激素缺乏症(GHD)与特发性矮身材(ISS)也是儿科内分泌门诊最常见的疾病。本研究回顾性分析2016年1月至2019年1月间我院儿科内分泌门诊127例身高低于同年龄正常身高均值-2SD儿童临床资料,旨在探讨GHD与ISS患者血清胰岛素样生长因子-1(IGF-1)及25羟维生素D[25-(OH)VD]变化情况,为保障儿童的正常生长发育提供临床指导。

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 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Translating local research into English as a lingua franca (ELF) connects local scholarship with global readership, but this process remains constrained by language barriers. Large language models (LLMs) offer advanced accessible solutions, but their responsible integration into academic translation requires a deeper understanding of the ...

Vocabulary Strategy Instruction in the Argentine EFL Context: Teachers’ Perspectives and Practices
International Journal of Applied Linguistics, EarlyView.ABSTRACT Despite extensive research on vocabulary strategy instruction (VSI), little has been known about teachers’ perspectives on how it is understood and implemented in practice. This study investigated Argentinian EFL teachers’ priorities in vocabulary instruction, their perceived knowledge of learner strategies for spoken vocabulary, and factors ...

野生动物学报, 2019 通过采用牛初乳、牛常乳、羊奶粉以及按不同日龄动物生长发育需要添加辅食的方法，对未吃到初乳的3只长颈鹿幼仔进行人工育幼。除1只长颈鹿幼仔出生时体弱（生母因病在产后10 d死亡），因网瓣胃阻塞治疗无效死亡外，其余2只长颈鹿幼仔成活，并且生长发育良好。与国内其他动物园人工哺育长颈鹿幼仔的方法相比，通过牛初乳、牛常乳、羊奶粉以及按不同日龄动物生长发育需要添加辅食的方法；选择适宜的喂奶工具及喂奶方式；营造适合幼仔生长发育环境等方法，取得了长颈鹿幼仔人工育幼的成功。本成功育幼 ...

野生动物学报, 2023 鹿类角柄终生有2次发育，第1次在胚胎期，第2次在青春期，出生后角柄的激活和首次发育对于鹿角再生极为重要，角柄的青春期发育对于鹿类个性及等级序位形成、鹿角大小、争夺配偶、种间竞争和应对天敌等有重要意义。利用红外测距仪，开展麋鹿（Elaphurus davidianus）角柄生长发育的宏观测量，结合青春期骨膜组织取样、血液激素水平和信号通路表达情况检测，对麋鹿角柄发育情况进行研究。结果表明：与成年不同，幼龄雄性麋鹿在第1年秋季开始出生后的首次角柄发育，由毛旋处长出骨质突起，翌年2—3月角柄长至2.5~3.0

Integrative Conservation, Volume 5, Issue 3, Page 255-267, September 2026.This study presents a comprehensive review of the 500‐year spatiotemporal evolution of global botanical gardens, identifying three major development stages—initial exploration (1543–1699), steady expansion (1700–1899), and rapid proliferation (1900–2020)—with six distinct sub‐stages. We propose a tripartite driving framework grounded in colonial botany
