9318273 Prum Studies of vertebrate breeding systems and social behavior have focused largely on near-term or proximate mechanisms that can be labelled ecological or environmental. Neglected have been determinants of behavior that are genetic in nature and entrained phylogenetically, that is present in recent common ancestors of the group of species under study. Dr. Richard Prum of the University of Kansas will use phylogenetic methods to investigate the historical pathways of evolutionary change in aspects of breeding and social behavior in a diverse lineage of neotropical perching birds, the cotingas. New characters of syringeal and skeletal morphology and traditional plumage features will be used to construct a robust hypothesis of phylogenetic relationships among the ca. 90 species of neotropical cotingids; collaborative field work in Brasil will provide new specimens for much of this research. This hypothesis of phylogeny will be used to analyze patterns of interspecies variation in social behavior and mating systems and to test comparatively several hypotheses about sexual color differences, sexual size differences, and display behavior homologies. The project contributes to avian systematics and to the synthesis of phylogenetic, ethological, and behavioral research on birds.

9318273 Prum 对脊椎动物繁殖系统和社会行为的研究主要集中在可以标记为生态或环境的近期或近期机制。 被忽视的行为决定因素本质上是遗传的，并且是系统发育的，存在于所研究的物种群体的最近共同祖先中。 堪萨斯大学的理查德·普鲁姆 (Richard Prum) 博士将利用系统发育方法来研究新热带栖息鸟类 (cotingas) 的不同谱系在繁殖和社会行为方面的进化变化的历史路径。 注射器和骨骼形态的新特征以及传统的羽毛特征将用于构建大约 ca 之间的系统发育关系的可靠假设。 90种新热带科廷科动物；巴西的合作实地工作将为这项研究的大部分提供新样本。 这种系统发育假说将用于分析社会行为和交配系统的种间变异模式，并测试有关性​​别颜色差异、性别大小差异和显示行为同源性的相对多个假设。 该项目有助于鸟类系统学以及鸟类系统发育、行为学和行为研究的综合。
