Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Studies have shown that organisms may adjust metabolic rates in response to thermal variability, highlighting metabolic plasticity as a key adaptive mechanism. Understanding the extent of metabolic plasticity of an organism is key to predicting its adaptation to climate

Conservation Biology, EarlyView.Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

Dianci bileiqi, 2017 飘弧和弧道在湿污表面沿泄漏距离的延伸是局部电弧演变的主要环节。利用高速摄像机观测了不同极性直流局部电弧在湿污表面的演变过程,并从气体放电理论分析和解释了出现上述现象的原因。观测结果表明,负极性电弧比正极性电弧飘弧更严重,且负极性电弧延伸速率高于正极性电弧;电弧延伸过程中,正极性电弧更容易出现分叉和并列弧道的现象,负极性电弧更易出现尖状的头部。负极性电弧更易飘弧是由于电弧与污层之间的流注更易发展,使负极性电弧和污层之间更易保持良好的导电通道,所以飘弧更易维持,也更严重;正极性电弧端部紧贴污层表面 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT This paper examines the features of metadiscourse across different teacher moves in university linguistics classroom discourse and the teaching strategies reflected in its use. The results reveal that teachers employ diverse metadiscourse during classroom interactions to support student reasoning.

Jianzhu Gangjiegou Jinzhan为了研究大高宽比矩形钢管混凝土柱的压弯性能，对大高宽比钢管混凝土短柱进行偏压试验并结合有限元模拟补充了4组试件进行对比，包括不同偏心率、高宽比、钢管壁厚度、截面尺寸情况下柱性能的对比分析。最后参考常用的4本国内外规范进行柱承载力计算，对比并判断现有规范是否适用。结果表明：试件破坏模式均为长边鼓曲，当荷载小于极限承载力的80%时，横截面高度上的应变分布服从平截面假定；随着偏心率增大，柱延性提升，在偏心率超过0.205后，柱延性开始下降；随着壁厚增加，柱延性提升，在壁厚达到8 mm后，柱延性开始下降 ...

Journal of Linguistic Anthropology, Volume 36, Issue 1, May 2026.Abstract Native speakerism in English language teaching (ELT) has become associated with Whiteness. However, how this association is sustained in everyday practices within China's unique socio‐cultural‐political context remains underexplored. This study examines the raciolinguistic construct of Mubai, a central recruitment criterion in China's ELT ...

Devouring the Invaders: The Racial‐Ecological Politics of the Chinese Crayfish Trade in Kenya
American Anthropologist, Volume 128, Issue 1, Page 183-194, March 2026.ABSTRACT This article examines entanglements of ecology, race, and foodways at Lake Naivasha in Kenya. Nonnative Louisiana red swamp crayfish (Procambarus clarkii), first introduced to Kenya in the 1960s, were once viewed as invasive but are now sought after as a delicacy among Kenya's Chinese community.
