9321316 Johnson This study examines the history of the avian genus Piranga (tanagers) and its relatives using a variety of kinds of data including plumage patterns, protein electrophoresis, mitochondrial DNA, and morphology. These data will allow generation of phylogenetic (genealogical) hypotheses for this group, which will be used as a backdrop for study of plumage dimorphism (males and females have different plumage colors and patterns), seasonal migration, and vocalizations. %%% The study will demonstrate whether correlations exist between plumage dimorphism and various life history traits, and this information will be used to test hypotheses about the significance of plumage dimorphism in birds.

9321316 Johnson 这项研究利用各种数据（包括羽毛图案、蛋白质电泳、线粒体 DNA 和形态学）研究了鸟类 Piranga 属（唐雀）及其近缘种的历史。 这些数据将允许生成该群体的系统发育（系谱）假设，该假设将用作羽毛二态性（雄性和雌性具有不同的羽毛颜色和图案）、季节性迁徙和发声的研究背景。 %%% 这项研究将证明羽毛二态性与各种生活史特征之间是否存在相关性，并且该信息将用于检验有关鸟类羽毛二态性重要性的假设。
