9623559 Kidwell This award will provide funds for materials and supplies as well as travel funds to support both collecting in Costa Rica and study of specimens at the American Museum of Natural History in New York. The support will enhance the dissertation of Patrick M. O'Grady II who is a graduate student with Dr. Margaret G. Kidwell at the University of Arizona. The student's dissertation project involves phylogenetic analysis of molecular sequence data from two independent genes (Adh and COII) to assess relationships among genera of flies in the family Drosophilidae (Insecta: Diptera). The genus Drosophila has been and is such a classic model system that a well-supported phylogeny of this group will have broad utility to other researchers addressing questions of reproductive biology, development, ecology, biogeography, genetic history, etc.. To date, hypothesized phylogenies for the family Drosophilidae have suggested contradictory or incongruent patterns of relationships. This project hopes to correct that situation and to use the two molecular data sets obtained to address analytical issues such as quantifying levels of congruence among competing hypotheses/phylogenies and whether combined evidence or separate analyses are of greater utility. This award will provide support for a graduate student pursuing studies of relationships among genera in the family of flies to which the genus Drosophila belongs. These flies are well known experimental animals for many areas of biology and understanding of their historical relationships will be of value in many kinds of research. The project will also investigate means of analyzing complex and sometimes conflicting molecular data. Support for the training of graduate students in modern systematic and population biology methodologies is important for maintaining the workforce of scientists capable of addressing the questions and issues of biodiversity which are of increasing global concern.

9623559 Kidwell该奖项将为材料和物资提供资金，以及旅行资金，以支持哥斯达黎加的收集和在纽约美国自然历史博物馆的标本研究。 支持将增强帕特里克·奥格雷迪二世（Patrick M. O'Grady II）的论文，他是亚利桑那大学玛格丽特·G·基德威尔（Margaret G. Kidwell）博士的研究生。 该学生的论文项目涉及从两个独立基因（ADH和COII）的分子序列数据的系统发育分析，以评估果蝇科（昆虫：二翅目）中蝇属之间的关系。 果蝇属曾经并且是一个经典的模型系统，以至于该小组的系统发育良好，将对其他研究人员具有广泛的实用性，该研究人员涉及生殖生物学，发展，生态学，生物地理学，遗传历史等。迄今为止，对家族果蝇的假定系统发育表明了对果蝇的假设形成的模式。 该项目希望纠正这种情况，并使用获得的两个分子数据集来解决分析问题，例如量化竞争假设/系统发育之间的一致性水平，以及合并的证据还是单独的分析是否具有更大的实用性。 该奖项将为研究生在果蝇所属的苍蝇家族中进行关系的研究生提供支持。 这些苍蝇是许多生物学领域的众所周知的实验动物，在许多研究中，对其历史关系的理解将具有价值。 该项目还将研究分析复合物，有时甚至是冲突的分子数据的手段。 支持在现代系统和人口生物学方法中培训研究生的研究对于维持能够解决日益增加全球关注的生物多样性问题和问题的科学家的劳动力很重要。
