Behavioral interventions to reduce demand for threatened freshwater turtles as pets
Conservation Biology, EarlyView.Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...

Exploring legal‐ and health‐risk messaging to reduce demand for elephant skin
Conservation Biology, EarlyView.Abstract Asian elephants (Elephas maximus) are poached for an illegal trade in their skins, which are used in traditional medicine in Africa and Asia. We explored whether messages about the legal and health risks of using elephant skin for medicinal purposes (stomach illness) could reduce such consumption.

, 2000 采用聚丙烯酰胺梯度凝胶电泳及特异性组织化学染色技术分析了鲤、鲫及其基因组叠加的不同组合个体的红细胞ＳＯＤ． ＥＳＴ和血红蛋白的电泳图谱。结果表明不同基因组组合及不同倍性的个体间存在由基因组差异导致的生化多态性，为不同倍性的鱼类的同工酶（ＳＯＤ）表达存在基因剂量效应提供了依据，证实了不同组合的ＳＯＤ亚基间有协同表达、累积作用。研究表明每个基因有其独特的调控机制，因而在杂种三倍体内三分之一的基因组亦能够表达产物。应用本研究的遗传学数据有益于构建基因组特异性品系 ...

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.

Synthesizing Empirical Research on Learner Metacognition in Second Language Writing
International Journal of Applied Linguistics, EarlyView.ABSTRACT Despite considerable research interest in learner metacognition in second language (L2) writing, there is not yet a review that synthesizes the existing empirical findings and discusses their implications. To fill the void, this systematic review synthesized 39 empirical studies on learner metacognition in L2 writing and examined their salient
