Functional Ecology, Volume 40, Issue 3, Page 636-654, March 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

Numerical simulation of plant root system stress response to coal mining disturbances in semiarid mining areas [PDF]
Root damage is a critical ecological issue affecting vegetation in semi-arid underground coal mining areas. The mechanisms and influencing factors of root stress damage induced by stress changes in the root-soil layer due to mining-induced rock mass ...

Shuitu Baochi Xuebao, 2005 黄土的风化主要为植物群落根系的物理作用及其所引起的生物化学作用。利用原状土柱淋滤实验装置及大型挖掘剖面壁法,在陕北黄土丘陵沟壑区进行野外实验研究,定量分析了林、草和农地土壤化学风化的剖面特征及动力学过程。研究结果表明,黄土土层的化学风化具有明显的垂直剖面分异特征,即风化速率随土层深度增加而递减。土壤化学风化的动力学过程可划分为急剧减小和稳定状态两个阶段。不同植被类型土壤风化速率及主导风化矿物组合类型的剖面差异主要受制于直径≤1mm的须根在剖面中的缠绕分布特征。植物根系对土壤风化作用的强化效应为油松林群落>

Functional Ecology, Volume 40, Issue 2, Page 534-552, February 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Non‐structural carbohydrates (NSC) are critical mediators of plant adaptation to fluctuating light environments. They are tightly coordinated with plant economic strategy, that is, leaf economics spectrum (LES) and root economics spectrum (RES).

International Journal of Applied Linguistics, Volume 36, Issue 1, Page 522-539, February 2026.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.

Experimental study and verification on tensile strength of remolded clay [PDF]
The tensile strength of clay is an important factor in determining the stability of soil slope. Due to the fragmentation of soil, the understanding of the tensile strength of clay is not clear. In this study, the uniaxial tensile test of remolded clay is
