Abstract

Abstract Individuals and populations can display variations in distinct aspects of their life histories, which could be reflected in their morphological characteristics. This study analyzed the mouthpart morphology of the crab Goniopsis cruentata in relation to environment, sex and stage of development. Our results indicate differences in the number of setae between developmental stages and environments, as well as the interaction between developmental stages and environments. There were no differences in setae types between stages, sexes or environments. There were differences in the shape of the ischium between adults and juveniles, with a more homogeneous ischium in juveniles than adults. We also found differences in food content between developmental stages, as well as an interaction between developmental stages and environment. Our results support an association between diet and morphology of mouthparts in G. cruentata , and that these apparatuses vary according to ontogenetic development and the environmental conditions that species are exposed to. These associations should be considered in studies that use these characteristics to verify morphological responses to environmental variations.

角蟹口器(Latreille, 1803)(十足目，短尾目，蟹科):与环境、性别和发育阶段有关的形态变异

个体和种群在其生活史的不同方面表现出差异，这可以反映在它们的形态特征上。本文分析了黄角蟹口器形态与环境、性别和发育阶段的关系。研究结果表明，不同发育阶段和环境对刚毛数量的影响存在差异，同时也表明发育阶段和环境之间存在相互作用。在不同的阶段、性别或环境中，刚毛类型没有差异。成虫和幼虫坐骨的形状存在差异，幼虫的坐骨比成虫更均匀。我们还发现了发育阶段之间食物含量的差异，以及发育阶段和环境之间的相互作用。我们的研究结果支持食性和口器形态之间的联系，并且这些器具根据物种的个体发育和所暴露的环境条件而变化。在使用这些特征来验证对环境变化的形态反应的研究中，应该考虑到这些关联。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
