RPG: Molecular History of Hawaiian Geraniums

Michaels 9407851本项目调查了六种原产于夏威夷群岛的Geralus。 这些物种具有独特的形态特征，使它们与属的其他物种区分开来，并表现出一系列不寻常的不同物种群。 因为这个群体既小又多样，夏威夷天竺葵是深入研究岛屿形态和物种形成后适应性形态变化的主要对象。 这项研究的目的是评估使用母系遗传的叶绿体基因和双亲遗传的核核糖体基因的内部转录间隔区的序列数据作为系统发育（系谱）分析的字符来源。 这项研究将有助于扩大我们对夏威夷生物历史的有限知识，并将为计划中的未来工作建立一个系统发育背景，研究两个濒危物种，Germinarboreum和G。多花

Michaels 9407851 This project investigates the six species of Geranium that are native and limited to the Hawaiian islands. These species share unique morphological features distinguishing them from the rest of the genus and exhibit an array of unusual divergent species groups. Because the group is both small and diverse, the Hawaiian geraniums are prime subjects for intensive study of island forms and the adaptive morphological changes following speciation. The study is designed to evaluate the use of sequence data from maternally inherited chloroplast genes and the internal transcribed spacer region of the biparentally inherited nuclear ribosomal genes as sources of characters for phylogenetic (genealogical) analysis. The research will contribute to expanding our limited knowledge of Hawaiian biotic history and will establish a phylogenetic context for planned future work on the genetic divergence between and within populations of the two endangered species, Geranium arboreum and G. multiflorum.
