Deep quantile regression for growth and maturation reaction norms

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 1, Page 111-124, January 2026.
Abstract Understanding species' growth and maturation responses to anthropogenic and environmental pressures is crucial for tracking demographic shifts, phenotypic change and ensuring population sustainability. Traditional regression methods often focus on modelling the conditional mean of life‐history traits, potentially overlooking heterogeneity in ...

Global drivers of the conservation–invasion paradox

open access: yesConservation Biology, Volume 39, Issue 5, October 2025.
Abstract The conservation–invasion paradox (CIP) refers to a long‐term phenomenon wherein species threatened in their native range can sustain viable populations when introduced to other regions. Understanding the drivers of CIP is helpful for conserving threatened species and managing invasive species, which is unfortunately still lacking. We compiled

Altered nutrient cycling functionality in seagrass meadows under a simulated future marine heatwave event

open access: yesNew Phytologist, Volume 247, Issue 6, Page 2616-2629, September 2025.
Summary Seagrasses are important contributors to environmental nutrient cycling in marine ecosystems and can improve water quality by absorbing excess nitrogen (N). However, these ecosystems are vulnerable to human‐mediated pressures, including marine heatwaves (MHWs), particularly those of longer duration. We performed an experiment simulating a 30‐d,

Assessing Closed Hydroponic Subsystems for Batavia Lettuce Growth Under Different Planting Densities

open access: yesWorld Water Policy, Volume 11, Issue 2, Page 427-438, May 2025.
ABSTRACT Hydroponic systems have the potential to be sustainable and alternative methods for food production that confer advantages of high production and better control of growth. However, only a few studies have focused on leafy vegetable growth in different subsystems and environmental variables.

Hydraulic traits are coordinated but decoupled from carbon traits in herbaceous species

open access: yesFunctional Ecology, Volume 39, Issue 5, Page 1302-1317, May 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant hydraulic traits primarily define the water regulation strategy, thus enabling a better understanding of vegetation structure, function and dynamics under varying hydro‐environments.

复合绝缘子均压环应用研究

open access: yesDianci bileiqi, 2004
采用有限元法计算了加装均压环后的电场分布,结果表明,外加均压环的均压效果较好。均压环不但能改善电场分布,而且还有引弧、防止金具电晕、延缓芯棒老化等作用;最后探讨了均压环设置应该注意的问题。

基于矩量法和蝴蝶交配优化算法的甚低频发射天线顶线绝缘子均压环优化设计

open access: yesGaoya dianqi, 2020
针对甚低频发射天线顶线绝缘子串电压分布不均匀极易产生电晕的问题,采用矩量法(method ofmoments,MOM)研究了不同均压环管径、半径、抬高距以及绝缘子串配置位置对瓷支柱绝缘子串电压分布的影响,提出了一种应用矩量法和蝴蝶交配优化算法(butterfly mating optimization,BMO)协同优化顶线绝缘子串均压环的新方法。该方法首先建立顶线绝缘子串MOM天线优化模型;然后,提取仿真得到的分压和天线效率并计算目标函数;利用BMO迭代得到顶线绝缘子相对位置和均压环结构参数 ...

Measuring the performance of Antarctic Treaty decision‐making

open access: yesConservation Biology, Volume 39, Issue 1, February 2025.
Abstract Agreements reached at the Antarctic Treaty Consultative Meetings (ATCMs) are among the primary means for addressing Antarctic conservation and environmental protection issues. However, according to contemporary scholars, Antarctic Treaty decision‐making is becoming increasingly unresponsive to the rising environmental challenges in the region.

500kV港城变电站绝缘子均压环放电现象研究

open access: yesGaoya dianqi, 2012
为了提高有限元数值仿真计算方法在研究外绝缘设备电场分布的准确性,对均压环与绝缘子串电场进行仿真分析,并通过设置仿真参数来获得均压环管径和安装位置最佳尺寸的依据。针对湛江500 kV港城变电站均压环对玻璃绝缘子串放电现象,运用ANSOFT软件建立了500 kV交流杆塔上均压环与绝缘子串全三维模型,研究了均压环管径和安装位置对绝缘子串电场分布影响的规律,并通过对电场强度的仿真分析解释了均压环对绝缘子频繁放电的原因。仿真分析中研究了均压环管径及其安装位置对最大电场强度的影响 ...
