Abstract

This study analysis the multivariate statistical relationships among cnidocyst types and tissues in terms of cnidocyst capsule size in the sea anemone O. muscosa. In a total of 12 individuals we measured the length of 30 unfired capsules of each cnida type, taken randomly from each of the following tissues: tentacles, acrorhagi, column, actinopharynx and mesenterial fila-ments. In these tissues, we found spirocysts, basitrichs, microbasic b-mastigophores, microbasic p-mastigophores and holotrichs. Thus, a total of 5400 measurements were made. Looking for a common pattern of variation, a principal components analysis (PCA) was performed on the data matrix, among cnidocyst types for each tissue and between tissues for each cnidocyst type. The results showed that the lengths of most cnidocysts, whether from the same or different tissues, are not statistically related to each other, suggesting that different forces (cnidogenesis, replacement dynamics, etc.), could affect in various forms the development and therefore the length of each cnida, depending on the type or tissue of origin.

海葵 Oulactis muscosa（Actiniaria: Actiniidae）中网囊大小的统计关系

本研究分析了海葵 O. muscosa 的网囊类型和组织之间在网囊大小方面的多元统计关系。我们共测量了 12 个个体的 30 个未烧结的各类型网囊的长度，这些网囊分别随机取自以下组织：触手、钩柄、柱状体、动咽和肠系膜。在这些组织中，我们发现了螺旋体、基托体、微基础 b 型胸腺、微基础 p 型胸腺和全托体。因此，总共进行了 5400 次测量。为了寻找共同的变异模式，对数据矩阵进行了主成分分析（PCA），包括每种组织的网囊类型之间以及每种网囊类型的组织之间。结果表明，无论是来自同一组织还是不同组织，大多数网囊的长度在统计学上互不相关，这表明不同的力量（网囊生成、替换动力学等）会以不同的形式影响网囊的发育，从而影响每个网囊的长度，这取决于网囊的类型或来源组织。

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.
