中文摘要:对同类的死亡作出响应并非人类独有，昆虫与其他动物也会面对同类死亡作出相近反应。在过去的几十年，大量与死亡相关的文章相继发表，直至2018年，研究人员整合了所有相关研究并提出了一个新的研究领域——进化死亡学，旨在从进化的角度综合研究人类及其他动物的死亡过程与影响。死亡相关化学物质的研究在该领域的形成和发展过程中发挥了重要作用。在进化死亡学这样的跨学科研究领域，往往会出现由于专业术语不统一而阻碍其发展的现象，因此，专业术语的标准化就显得尤为重要。该文将循证系统评价和荟萃分析中的首选报告项目（Preferred Reporting Items for Systematic Reviews and Meta-analysis，PRISMA）与关键词共现联合分析相结合，对已发表文献中死亡相关化学物质的术语进行了整理和量化分析，总结和探讨了相关术语使用中的主要问题，并对未来相关术语的标准化使用提出了建议。结果表明在已存在可用相关术语的情况下，其他术语仍不断被创造和引入；同一领域内不同术语用于描述相同的概念；相同术语用于描述其他领域的不同概念。由于现有术语已足够描述可能出现的死亡相关化学物质，且目前对死亡及其相关化学物质在调控行为方面的机理和进化知之甚少，建议今后的研究尽量避免引入新术语，并使用死亡信号（death cue）作为描述死亡相关化学物质的标准术语。精简统一的标准化术语不仅有利于从进化角度跨物种比较研究死亡现象，还将推动进化死亡学这一新兴综合学科的整体发展。

Abstract:Chemicals associated with death are utilized by insects and other animals to mediate their responses to dead conspecifics. For the past decades, there has been an influx of publications associated with death and death-related chemicals, culminating in the introduction of Evolutionary Thanatology in 2018, an interdisciplinary field of study focusing on the phenomena of death and dying across animal taxa. Integrated and interdisciplinary research of chemicals involved in death recognition plays an important role in the formation and growth of this exciting new field from biological and evolutionary perspectives. Here, combining evidence-based Preferred Reporting Items for Systematic Reviews and Meta-analysis(PRISMA) with a keyword co-occurrence analysis, a quantitative review of terminology used in studies of chemicals associated with dead conspecifics was carried out. Given that excessive use of newly coined or improvised terminology and overlapping terms within and between research fields may hinder the growth of this emerging field, we suggest limiting the introduction of novel terminology if existing terms can cover new findings among death-related chemicals. Considering that the field of Evolutionary Thanatology is still in its infancy, death cue might be a term-of-choice due to the lack of information on the mechanistic, functional, and evolutionary bases of chemicals associated with dead conspecifics. A standardized/streamlined set of terminology not only affords the opportunity for comparative studies across broad taxa to trace the evolutionary histories of death-related chemicals, but also facilitates the development and growth of Evolutionary Thanatology as a whole.
