Dizhen xuebao, 2018 2010年8月至2015年12月，福建仙游地区发生了一系列小震群活动。基于孔隙压力扩散机制对精定位的小震数据进行分析，结果显示仙游震群序列在空间上呈丛集分布，且具有明显的分区现象，发震时间受金钟水库水位变化的调制作用较为明显。5个分区（A—E）的流体孔隙压力扩散系数分别为0.04，0.08，0.07，0.12和0.05 m2/s，伴随着地震活动性由强至弱，孔隙压扩散系数呈先增后减的变化规律。仙游震群位于断裂构造发育区内，震中分布优势方向与石苍断裂一致，沿着断裂走向的孔隙压扩散系数最大 ...

Coordination of cortex modifications in time, space, and under stress
New Phytologist, Volume 248, Issue 4, Page 1677-1685, November 2025.Summary In roots, cell‐type‐specific differentiation enables specialized responses to environmental stress. The cortex, located between the vasculature and epidermis, is a key site for stress‐responsive modifications. The distinct specializations of the cortex are controlled by developmental, positional and environmental signals.

New Phytologist, Volume 248, Issue 2, Page 656-671, October 2025.Summary Formation of an aqueous continuum from the leaf surface to the sub‐stomatal cavity is a key process, affecting the foliar entry of solutes, particles, and pathogens. However, the factors controlling the transition from a water droplet to the formation of a continuous water film remain poorly understood.

Zhejiang Daxue xuebao. Lixue ban, 2002 从陆西凹陷的实际资料出发,分析了裂缝在油气勘探中的作用及不同类型裂缝的特征,研究了影响构造裂缝发育的因素,认为构造裂缝的发育受构造部位、孔隙度、断层等多种因素的影响,探讨了裂缝发育程度与相关影响因素之间的定量关系,给出了拟合求曲率的方法、与最近断层距离的计算方法,建立了裂缝密度的定量化预测方法--拟合曲率综合预测裂缝方法和相应的评价标准,并对陆西凹陷的裂缝分布进行预测.

New Phytologist, Volume 247, Issue 6, Page 2678-2696, September 2025.Summary Many plants reproduce asexually by generating clonal progeny from vegetative tissues, a process known as vegetative reproduction. This reproduction mode contrasts with sexual reproduction, which enhances genetic diversity. The bryophyte Marchantia polymorpha L.

Dizhen xuebao, 2018 本文收集了广西龙滩水库地震监测台网2006年9月至2016年12月精定位后的3 382次ML≥0地震的数字波形资料，采用二维衰减成像技术获得了龙滩水库库区的QS二维分布图像。结果显示：龙滩水库库区QS的横向不均匀变化明显，QS低值区围绕着库区近似呈环形分布；在QS低值分布区附近，大多为河流与断裂带的交汇处；QS低值分布主要对应于透水性较强的岩性地区。以上现象表明QS低值分布受水、断裂、岩性等3种因素的影响，由此初步推断库水可能沿着断裂上的岩石破碎带及节理、裂隙发育地区和具有较强透水性岩层区域向下渗透 ...

PLANTS, PEOPLE, PLANET, Volume 7, Issue 2, Page 367-381, March 2025.Parasitic plants that deprive crops of water and nutrients are an increasingly concerning food security issue, affecting the livelihood of millions of subsistence, small‐ and mid‐scale farmers. An in‐depth understanding of parasite–host interactions is required to develop species‐specific and ecologically sustainable parasite management methods.

New Phytologist, Volume 245, Issue 1, Page 318-331, January 2025.Summary Drought predisposes forest trees to bark beetle‐induced mortality, but the physiological mechanisms remain unclear. While drought‐induced water and carbon limitations have been implicated in defensive failure and tree susceptibility, evidence demonstrating how these factors interact is scarce.

Shuitu Baochi Xuebao, 2016 通过对湖北通城花岗岩崩岗区发育典型的各层次土体（淋溶层、淀积层、过渡层、母质层）进行干湿循环试验，分析干湿交替次数对各层次土体裂隙发育、崩解性、抗剪强度的影响。结果表明，在干湿循环影响下，土体产生并逐渐发育裂隙，在第2次循环后，土体产生主要裂隙，裂隙比显著增加，此后循环发育出细小裂隙。4次交替后4个层次土体的裂隙比表现为淀积层＞淋溶层＞过渡层＞母质层。随着干湿循环次数的增加，裂隙发育，各层次土体崩解性不断增加，淋溶层和淀积层崩解缓慢，而过渡层和母质层能够在极短时间内完全崩解；随着干湿循环次数的增加 ...

New Phytologist, Volume 242, Issue 1, Page 49-60, April 2024.Summary Tree stem methane emissions are important components of lowland forest methane budgets. The potential for species‐specific behaviour among co‐occurring lowland trees with contrasting bark characteristics has not been investigated. We compare bark‐mediated methane transport in two common lowland species of contrasting bark characteristics ...
