ABSTRACTTOTAL EVIDENCE PHYLOGENY OF GOBIOIDEI (TELEOSTEI: PERCIFORMES) AND CLADISTIC BIOGEOGRAPHY The fish suborder Gobioidei includes more than 2000 extant species of small fishes found throughout the tropical, subtropical, and temperate regions of the world, in freshwater and nearshore marine habitats. Many gobioids live on or near the bottom, often in burrows. Many others are reef-dwellers, a few are oceanic, and some estuarine representatives have the ability to breathe air. Their wide distribution and great diversity of form and ecology make gobioids ideal for studies of broad questions in vertebrate evolution and biogeography. However, the incredible gobioid diversity has also hindered investigations of their evolutionary relationships, and no comprehensive phylogenetic hypothesis for gobioids has been advanced. Previous studies have focused on small groups of taxa or restricted suites of characters, and because of the fishes' small size, the morphological characters identified are often reductive and highly variable. The closest relatives of Gobioidei are unknown, and the classification has been in flux. Currently, the roughly 270 gobioid genera are classified in nine families, some containing only a single genus. The larger families (Eleotrididae, Gobiidae) are almost certainly not natural groups, and the relationships of species within those families, and among families, are unknown.This study seeks to resolve gobioid relationships using a total evidence approach and focusing primarily on basal gobioid groups and outgroups. DNA sequence data from five genes (four mitochondrial and one nuclear) will be combined with osteological and myological characters. The data will be analyzed separately and combined, and the resultant phylogeny will then be used to produce a classification for the suborder. The phylogeny will be used to examine the historical biogeography of gobioids, using cladistic biogeographical techniques to discover congruent patterns of area relationships and examine the origins of gobioid diversification. The common assumption that gobioids originated in a marine environment and diversified into freshwater once or repeatedly will be investigated by mapping the distribution of habitats on the taxon cladogram.Gobioid fishes have been studied for over a century but the group is so large, diverse, and widely distributed that a comprehensive phylogenetic and biogeographic study has never been attempted. This study will provide the first such comprehensive phylogenetic hypothesis and provide the basis for exploring the biogeography of a major group of fishes. It will also provide a historical foundation for future studies that will examine ecology, adaptation, and development, using the potential of this diverse group as a model for research on many aspects of evolutionary biology.

虾虎鱼亚目（硬骨鱼纲：鲈形目）的系统发育和分支生物地理学虾虎鱼亚目包括2000多种现存的小型鱼类，分布于世界的热带、亚热带和温带地区的淡水和近岸海域。许多虎鱼生活在底部或附近，通常在洞穴中。 其他许多是珊瑚礁居民，少数是海洋性的，一些河口的代表有呼吸空气的能力。它们的广泛分布和巨大的多样性的形式和生态使虎鱼理想的研究广泛的问题，在脊椎动物进化和鱼类地理学。然而，令人难以置信的虎鱼多样性也阻碍了他们的进化关系的调查，并没有全面的系统发育假说虎鱼已经先进。 以前的研究集中在小类群或有限的字符集，因为鱼的小尺寸，识别的形态特征往往是还原和高度可变的。Gobioidei的近亲是未知的，分类一直在变化。目前，大约有270个属被分为9个科，有些只有一个属。较大的家庭（Eleotrididae，Gobiidae）几乎可以肯定不是自然群体，和这些家庭内的物种的关系，家庭之间，是unknow.This研究旨在解决gobioid的关系，使用全证据的方法，主要集中在基础gobioid组和外群。 来自五个基因（四个线粒体和一个核）的DNA序列数据将与骨骼学和肌肉学特征相结合。 这些数据将被单独分析和组合，然后将产生的系统发育将被用来产生一个分类的亚目。该系统将用于研究虎鱼的历史地理学，使用分支系统地理学技术来发现区域关系的一致模式，并研究虎鱼多样性的起源。常见的假设，即虾虎鱼起源于海洋环境和多样化到淡水一次或多次将调查的栖息地分布的分类系统cladogram.Gobioid鱼类已经研究了一个世纪，但组是如此之大，多样性和广泛的分布，一个全面的系统发育和鱼类地理学研究从未尝试。这项研究将提供第一个这样全面的系统发育假说，并为探索一个主要鱼类类群的系统发育提供基础。它还将为未来的研究提供历史基础，这些研究将研究生态学，适应和发展，利用这个多样化群体的潜力作为进化生物学许多方面研究的模型。
