项目摘要

Title: Phylogenetic Relationships of Sunfishes and Basses, Family Centrarchidae, as evidenced by Mitochondrial DNA sequences and Morphological Characteristics.Mayden and Harris9903794 The Centrarchidae (sunfishes and basses) are a group of 31 species in nine genera found only in North America. This family constitutes a major component of the fish communities in most eastern North American warm-water ecosystems and are highly prized in recreational fisheries and aquaculture. In addition, centrarchids have been the focus of many behavioral, developmental, ecological, evolutionary, functional morphological, genetic and host-parasite coevolution studies. Given the popularity of these fish as model organisms across the disciplines listed above, it is surprising that genealogical relationships among species within the family have received minimal systematic attention, and those hypotheses that have been proposed either did not employ a phylogenetic methodology, were based on questionable character data, or failed to encompass all taxa within the family. In addition, all attempts at phylogenetic reconstruction for centrarchids lack an appropriate outgroup, in part, because phylogenetic relationships within Perciformes remain largely unresolved. Regardless, the existing hypotheses of relationships of these important fishes are confusing. A phylogenetic analysis of centrarchid relationships based on diverse morpholgical data sets by other researchers, and a new data set generated from the present study using mitochondrial cytochrome b gene sequences will provide an opportunity to establish the monophyly of the family, generate a phylogenetic hypothesis of centrarchid species relationships, and determine the sister-group to the Centrarchidae. In addition, we will re-evaluate the question of the use of ontogenetic information in polarizing and ordering characters. Through separate and combined analyses of data sets that currently exist and against the background of the large DNA sequence data set, a study of character congruence (homoplasy) and taxonomic congruence among these independent data sets also is proposed. These data sets will be used in parsimony analyses to reassess the efficacy of using ontogeny in assessing homology and character polarity, determine the extent to which data sets converge on a single phylogenetic hypothesis, and establish a stable classification for this family, and will be useful in studies of rates of evolution and modes of speciation, biogeography, evolution of functional morphology patterns, behaviors, ecologies, and host-parasite coevolution.
标题:由线粒体DNA序列和形态特征证明的向日葵和鲈科的系统发育关系。Mayden和Harris9903794向日葵属(太阳鱼和鳕鱼)是一个由9属31种组成的类群,仅发现于北美。该科是北美东部大多数暖水生态系统鱼类群落的主要组成部分,在休闲渔业和水产养殖中受到高度重视。此外,中央原虫一直是许多行为、发育、生态、进化、功能形态、遗传和寄主-寄生虫共同进化研究的焦点。鉴于这些鱼作为上述学科的模式生物广受欢迎,令人惊讶的是,该科内物种之间的系谱关系只得到了最少的系统关注,所提出的假设要么没有采用系统发育方法,要么基于有问题的特征数据,或者没有涵盖该科内的所有分类群。此外,所有试图重建中心类系统发育的尝试都缺乏一个合适的外类群,部分原因是Perciformes内的系统发育关系在很大程度上仍未解决。无论如何,现有的关于这些重要鱼类之间关系的假设是令人困惑的。基于其他研究人员的不同形态数据集对中心性关系的系统发育分析,以及本研究利用线粒体细胞色素b基因序列产生的新数据集,将为建立该科的单系性,产生中心性物种关系的系统发育假说,并确定中心性群科的姐妹群提供机会。此外,我们将重新评估个体发育信息在字符极化和排序中的使用问题。通过对现有数据集的单独和组合分析,并以大型DNA序列数据集为背景,研究了这些独立数据集之间的特征同余(同质性)和分类同余。这些数据集将被用于简约分析,以重新评估使用个体发育学评估同源性和特征极性的有效性,确定数据集在单一系统发育假说上的收敛程度,并建立该家族的稳定分类,将有助于研究进化速度和物种形成模式、生物地理学、功能形态模式的进化、行为、生态和宿主-寄生虫的共同进化。
