This is a proposal to continue and extend work in progress on the systematics of salamanders from the western United States and from Middle America. The main emphasis of the study is the morphology and genetic variation of the species. The main morphological topic is the development and comparative structure of the brains of salamanders that use extreme fast and far- reaching tongues to capture prey. Comparative anatomical studies of other parts of the organism will also be conducted. Both protein and nucleic acid variation will be studied in a number of species. A long range goal of this study is to determine how many species of salamanders there are in these regions, and to determine the patterns of phylogenetic relationships among them, as they are important to our understanding of ecology and earth history.

这是一项继续和延长正在进行的工作的建议 关于美国西部蝾螈的分类学 和美国中部。 研究的重点是 物种的形态和遗传变异。 主要 形态学的主题是发展和比较结构 蝾螈的大脑，使用极快和远- 伸出舌头捕捉猎物 比较解剖 也将进行生物体的其他部分。 两 蛋白质和核酸的变异将在一些研究 物种 这项研究的一个长期目标是确定如何 许多种类的蝾螈在这些地区， 确定它们之间的系统发育关系的模式， 因为它们对我们理解生态学和地球很重要 历史
