项目摘要

9701413 Springer This award will provide funds for materials and supplies to enhance the dissertation research of Ms. Angela Burk, a doctoral student at the University of California - Riverside who is working under the supervision of Dr. Mark Springer. Ms. Burk's dissertation research involves acquisition of DNA sequences from three mitochondrially-encoded genes (12S rRNA, valine tRNA, and 16S rRNA) and one nuclear-encoded gene (protamine P1) from a representative of all living genera of Macropodidae. Macropodids consist of kangaroos, wallabies, and rat-kangaroos, and are the most species-rich group of all known marsupials. The groups contains 62 living species that occupy a wide diversity of habitats, including tropical rain forests, alpine tussock grasslands, and arid inland plains. Numerous attempts have been made previously to unravel the phylogenetic history of Macropodidae, but thus far complete resolution has not been obtained. Ms. Burk's research will establish such a phylogenetic framework and, in addition, will provide estimates of divergence times of examined taxa. Her research also will examine the historical development of several morphological characters and character complexes, address questions regarding rates of evolution (divergence) of each gene, and evaluate different character-weighing approaches for phylogenetic inference. Support for training of graduate students in modern technologies is critical to maintain the workforce of scientists capable of addressing questions and issues in global biology.

9701413 Springer该奖项将为材料和用品提供资金，以增强加利福尼亚大学的博士生Angela Burk女士的论文研究 - Riverside -Riverside在Mark Springer博士的监督下工作。伯克女士的论文研究涉及从三个线粒体编码的基因（12S rRNA，valine tRNA和16S rRNA）和一个核编码基因（精胺P1）中获取DNA序列。大型根源由袋鼠，小袋鼠和大鼠袋鼠组成，是所有已知的有袋动物中种类富含物种的群体。这些群体包含62种占有广泛栖息地的活物种，包括热带雨林，高山杜塞克草原和干旱的内陆平原。以前已经进行了许多尝试，以揭示大能科的系统发育史，但迄今为止尚未获得完整的分辨率。伯克女士的研究将建立这样的系统发育框架，此外，还将提供检查分类单元的分歧时间。她的研究还将研究几种形态特征和特征复合物的历史发展，解决有关每个基因进化速率（差异）的问题，并评估了系统发育推断的不同特征推定方法。支持对现代技术的研究生的培训对于维持能够解决全球生物学问题的科学家的劳动力至关重要。
