9623763 MITTON This award will provide funds for materials and supplies as well as extended travel for field studies in the southwestern US, Mexico and Guatemala related to the dissertation research of a graduate student, Scott T. Kelley, working with Dr. Jeffry B. Mitton at the University of Colorado, Boulder. Dr. Brian Farrell, who recently left the University of Colorado to accept a faculty position at Harvard University, is a coPI and will be involved in training the student in methods of phylogenetic analysis of molecular data. The research project of this student has two components: 1) a combined data phylogenetic analysis of species relationships among bark beetles in the genus Dendroctonous (Insecta: Coleoptera: Scolytidae), utilizing molecular (mtDNA) sequence data and morphological data and 2) population level studies of the degree of genetic diversity among populations of two of the species across a broad geographic range. Information from both studies will be utilized to test hypotheses concerning dietary shifts and specializations for these wood destroying insects. This award will provide support for a graduate student pursuing studies of the change in dietary breadth/specialization through time for a genus of beetles which includes some species that are major forest/timber pests. The results have potential value for applied research with major economic implications. 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.

9623763 MITTON 该奖项将为美国西南部、墨西哥和危地马拉的研究生 Scott T. Kelley 与博尔德科罗拉多大学 Jeffry B. Mitton 博士的论文研究相关的材料和用品以及长期旅行提供资金。 Brian Farrell 博士最近离开科罗拉多大学，前往哈佛大学担任教职，他是一名 coPI，将参与对学生进行分子数据系统发育分析方法的培训。该学生的研究项目有两个组成部分：1）利用分子（mtDNA）序列数据和形态学数据，对树皮甲虫属（昆虫纲：鞘翅目：小蠹科）树皮甲虫之间的物种关系进行综合数据系统发育分析；2）在广泛地理范围内对两个物种种群之间的遗传多样性程度进行种群水平研究。 这两项研究的信息将用于检验有关这些木材破坏昆虫的饮食变化和专门化的假设。 该奖项将为一名研究生提供支持，研究甲虫属的饮食广度/专业化随时间的变化，其中包括一些主要的森林/木材害虫物种。 研究结果对于具有重大经济意义的应用研究具有潜在价值。 支持现代系统生物学和群体生物学方法学研究生的培训对于维持科学家队伍能够解决全球日益关注的生物多样性问题非常重要。
