9420041 Siegel-Causey Large water birds-penguins, loons, grebes, albatrosses and shearwater, pelicans and allies, herons and storks- have been considered to comprise the earliest branching groups of birds. This project will examine phylogenetic relationships among the pelican-like birds (Pelicaniformes) using molecular sequence data. The phylogenetic framework will be used to address morphologic evolution as well as the evolution of social behavior in these birds. %%% The proposed study will help unravel the relationships among pelicaniform birds and their close relatives. It will provide a better understanding of the patterns of molecular evolution in mitochondrial ribosomal genes. It will also provide the knowledge necessary to address such macroevolutionary questions as whether the Pelicaniformes are a morphologically and ecologically diverse clade of birds or, if this diversity is simply an artifact of lumping together unrelated species. ***

9420041只西格尔-考西大型水鸟--企鹅、土鸟、灰鸟、信天翁和剪毛鸟、鹈鹕及其盟友、苍鹭和鹤--被认为是鸟类中最早的分支类群。这个项目将使用分子序列数据来研究鹈鹕类鸟类(鹈鹕形目)之间的系统发育关系。系统发育框架将用于研究这些鸟类的形态进化和社会行为的进化。这项拟议的研究将有助于揭开鹈鹕类鸟类及其近亲之间的关系。这将有助于更好地理解线粒体核糖体基因的分子进化模式。它还将提供必要的知识来解决这样的宏观进化问题，例如鹈鹕是形态和生态上多样化的鸟类支系，还是这种多样性只是将无关物种混为一谈的产物。***
