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：人类Centrarchidae的系统发育关系，线粒体DNA序列和形态学特征所证明的。Maydenand Harris9903794 Centrarchidae（Sunfishes and Basses）是北部北部31种的31种。该家族构成了大多数北美北美温水生态系统中鱼类群落的主要组成部分，并且在休闲渔业和水产养殖中高度评价。 此外，中心构造一直是许多行为，发育，生态，进化，功能形态，遗传和宿主 - 寄生虫共同进化研究的重点。 鉴于这些鱼是上面列出的学科中的模型生物的普及，令人惊讶的是，家庭内部物种之间的家谱关系受到了最小的系统关注，并且那些提出的假设未采用系统发育方法论，是基于可疑的角色数据，或者未能包含家庭中的所有分类。 此外，对中心构造的系统发育重建的所有尝试都缺乏适当的外部群，部分原因是Perciformes内的系统发育关系仍然在很大程度上无法解决。 无论如何，这些重要鱼类关系的现有假设令人困惑。基于其他研究人员的多样性数据集的中心构造关系的系统发育分析，以及使用线粒体细胞色素B基因序列从本研究中生成的新数据集将提供一个机会，可以建立家庭单亲性，从而产生Centrarch物种关系的系统发育假设，并确定Centrarch sistertrarch the Sister-rarch to sentrarchae to sentrarchae to sentrarkicae to centrarkicae to sentrarkicae to sentrarkicae to sentrarkicae。 此外，我们将重新评估在两极分化和订购字符中使用个体遗传信息的问题。 通过对当前存在的数据集的单独和合并的分析，以及在大型DNA序列数据集的背景下，还提出了对这些独立数据集中角色一致性（同质性）和分类一致性的研究。 这些数据集将用于简约分析中，以重新评估使用个体发育在评估同源性和性格极性方面的功效，确定数据集对单个系统发育假设的融合程度，并为该家族建立稳定的分类，并在该家庭中建立一个稳定的分类，并将在形成率和模式的研究速率和模式，生物学和模式，功能和模式，功能和模式的研究中有用。宿主 - 寄生虫共同进化。
