Abstract

The phylogeny of the very diverse Neotropical fish family Characidae has been the subject of several recent contributions based on morphological characters, molecular data or both in combined analyses. In cases of conflict between these kinds of data, resolution by combined analyses most often tends to agree with the molecular evidence, given the disproportionate number of characters it contains in comparison with morphological datasets. This happens especially after the advent of massive DNA sequencing methods. In this contribution, we present the most comprehensive set of characters from sperm and spermiogenesis of the Characidae. Since these traits are not expected to be functionally correlated with the general morphology or molecular markers, we consider them a third source of data. We provide a phylogenetic analysis from a combined dataset of seven molecular markers (6444 characters), general morphology (520 characters) and reproductive features (94 characters) coded for 165 species of characiform fishes. Parsimony analyses were done under extended implied weighting under 30 different combinations of weighting schemes and strengths. Most parsimonious trees from two different weighting conditions were selected as representative samples of the obtained topologies, in order to evaluate the performance of the reproductive characters. One of these hypotheses is more conservative regarding the currently accepted phylogenies and the other is the most parsimonious tree that we found as the best correlated with the morphological data. Reproductive characters are shown to be more homoplastic than general morphology and DNA, but provided synapomorphies for 23–24 nodes that had no morphological synapomorphies, justifying their use in phylogenetic analyses. Also, in combination with data from general morphology and considering details of the phylogenetic analysis, they showed to have the potential to challenge well‐established hypotheses based on molecular data.

特征科精子系统发育(Teleostei, characteries)

非常多样化的新热带鱼科特征的系统发育已经成为最近基于形态特征、分子数据或两者结合分析的几个贡献的主题。在这些类型的数据之间存在冲突的情况下，结合分析的结果往往倾向于与分子证据一致，因为与形态学数据集相比，分子证据包含的字符数量不成比例。这种情况尤其发生在大规模DNA测序方法出现之后。在这篇文章中，我们介绍了最全面的一套来自精子和精子发生的特征。由于这些性状与一般形态或分子标记在功能上不相关，我们认为它们是第三个数据来源。本文对165种特征性鱼类的7个分子标记(6444个字符)、一般形态(520个字符)和生殖特征(94个字符)进行了系统发育分析。在30种不同的加权方案和强度组合下进行了扩展隐含加权的简约性分析。选取两种不同加权条件下的最节省树作为拓扑结构的代表性样本，以评价繁殖性状的性能。其中一种假说相对于目前公认的系统发生假说更为保守，而另一种假说则是我们发现的与形态学数据最相关的最简约树。生殖性状显示出比一般形态和DNA更具同质性，但为23-24个没有形态突触的节点提供了突触，证明了它们在系统发育分析中的应用。此外，结合一般形态学数据和考虑系统发育分析的细节，它们显示出挑战基于分子数据的既定假设的潜力。

期刊介绍： Zoologica Scripta publishes papers in animal systematics and phylogeny, i.e. studies of evolutionary relationships among taxa, and the origin and evolution of biological diversity. Papers can also deal with ecological interactions and geographic distributions (phylogeography) if the results are placed in a wider phylogenetic/systematic/evolutionary context. Zoologica Scripta encourages papers on the development of methods for all aspects of phylogenetic inference and biological nomenclature/classification. Articles published in Zoologica Scripta must be original and present either theoretical or empirical studies of interest to a broad audience in systematics and phylogeny. Purely taxonomic papers, like species descriptions without being placed in a wider systematic/phylogenetic context, will not be considered.
