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 ...

How endorser attributes influence conservation communication
Conservation Biology, EarlyView.Abstract Conservation communication often uses the celebrity endorsement strategy. However, robust evidence regarding its effectiveness is still limited. More importantly, practitioners do not have guidelines for selecting an ideal endorser because there is no clear consensus on what endorser attributes are most critical.

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.

The Impact of AI‐Assisted L2 Learning on Learners’ Emotions: A Meta‐Analysis
International Journal of Applied Linguistics, EarlyView.ABSTRACT The scope of research on AI‐assisted second/foreign language (L2/FL) learning has expanded beyond learning outcomes to focus on learners’ emotional experiences. Despite their proliferation, existing empirical findings are inconsistent, and few studies have systematically synthesized the impacts of AI‐assisted L2 learning on learners’ emotional

International Journal of Applied Linguistics, EarlyView.ABSTRACT In this study, control–value theory (CVT) was used to investigate how students’ perceptions of the classroom environment shape their anxiety in the context of English as a foreign language (EFL) learning through the mediating effects of control and intrinsic value appraisals.

四川大学学报. 自然科学版, 1979 关于丢番图方程x4-Dy2=1,D>0,且不是平方数,（1）Ljunggren,Cohn和本文作者都有过不少工作,现简述如下:1.1942年,Ljunggren证明了丢番图方程（1）最多只有二组正整数解（x,y）。2.1966年,Ljunggren证明了,当D=ρ是一个奇素数时,则丢番图方程（1）在ρ≠5,29时,没有正整数解。在ρ=5时,仅有正整数解x=3,y=4,在ρ=29时,仅有正整数解x=99,y=1820。
