9508574 Wake This research involves study of the evolutionary relationships of terrestrial lungless salamanders , family Plethodontidae. The proposed work concentrates on obtaining DNA sequence data and new morphological data for the Bolitoglossini tribe so that explicit phylogenetic hypotheses can be tested at several hierarchical levels. %%% Not only does this study have value for understanding the evolutionary history of members of this group, but knowledge of this group will provide information of critical value in developing land use and conservation strategies in the future. Several of the taxa involved are federally listed species and some others may already be extinct. ***

9508574 Wake这项研究涉及研究Plethodontidae家族陆地无肺蝾螈的进化关系。拟议的工作集中在获得的DNA序列数据和新的形态数据Bolitoglossini部落，以便明确的系统发育假说可以在几个层次进行测试。 这项研究不仅对了解这一群体成员的进化历史有价值，而且对这一群体的了解将为未来制定土地利用和保护战略提供重要价值的信息。其中几个分类群是联邦政府列出的物种，其他一些可能已经灭绝。 ***
