Deep quantile regression for growth and maturation reaction norms
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
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

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
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
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.

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
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
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.
