9729191 DeSALLE Fruit flies (family Drosophilidae) have been used for more than a century as model systems to explore major issues in biological and environmental sciences. The Hawaiian Drosophilidae, an assemblage of about a thousand species, represent the premier example of founder-effect speciation and adaptive radiation on oceanic islands, but except for the picture-winged cluster of about 100 species, their taxonomy and systematics are poorly known. In this collaborative project, the systematic biology of the Hawaiian drosophilids will be reviewed, and a robust phylogeny reconstructed. The work will include field collections, descriptions of species, establishment of cultures, and collections of morphological, molecular and behavioral characters for phylogenetic analysis. The resulting analysis is expected to be definitive, and to support future analyses of developmental and behavioral pathways in these flies.

一个多世纪以来，果蝇一直被用作研究生物和环境科学重大问题的模型系统。夏威夷果蝇科（Hawaiian Drosophilidae）大约有1000个物种，是海洋岛屿上创始效应物种形成和适应性辐射的主要例子，但除了大约100个物种的图片翼群外，它们的分类学和系统学知之甚少。在这个合作项目中，将回顾夏威夷果蝇的系统生物学，并重建一个强健的系统发育。这项工作将包括野外采集、物种描述、培养的建立，以及用于系统发育分析的形态、分子和行为特征的收集。结果的分析有望是明确的，并支持未来对这些果蝇的发育和行为途径的分析。
