9321395 Hafner Pocket gophers and their louse parasites have been shown to have similar phylogenetic (genealogical) histories. The proposed study analyses this relationship in detail by examining pocket gophers and two groups of chewing lice that parasitize the gophers. In addition it examines the historical relationships between gophers and an internal parasite, the whipworms. The study will compare phylogenies of gophers and their parasites using mitochondrial DNA nucleotide sequence differentiation. These data offer an opportunity directly to quantify the genetic change associated with the host and parasite phylogenies, and to evaluate the historical importance of vertebrate host-parasite associations.

9321395哈夫纳袋地鼠及其寄生的虱子具有相似的系统发育（系谱）史。本研究通过研究袋地鼠和寄生在袋地鼠身上的两组咀嚼虱，详细分析了这种关系。此外，它还研究了地鼠与体内寄生虫鞭虫之间的历史关系。本研究将利用线粒体DNA核苷酸序列分化比较地鼠及其寄生虫的系统发育。这些数据提供了一个机会，可以直接量化与宿主和寄生虫系统发育相关的遗传变化，并评估脊椎动物宿主-寄生虫关联的历史重要性。
