Hybrid zones are unique arenas in which to study a variety of evolutionary mechanisms. The proposed project aims to build on traditional methods of hybrid zone research by integrating genetic, environmental, and behavioral components to study a recently described hybrid zone between two subspecies of the Desert Woodrat, Neotoma lepida. The project will quantify the frequency of hybridization using genetic data, will determine how female mating preferences influence the production of hybrid offspring, will establish whether habitat variation is associated with hybridization, and will compare survivorship and reproductive success between hybrid and non-hybrid individuals. Both undergraduate and advanced high school students will assist in field and laboratory data collection, including rural and local Native American students who are the first members of their families to attend college.

杂交区是研究各种进化机制的独特场所。拟议的项目旨在建立在传统的杂交区研究方法的基础上，通过整合遗传，环境和行为成分来研究最近描述的沙漠Woodrat，Neotoma lepida两个亚种之间的杂交区。该项目将利用遗传数据量化杂交的频率，将确定雌性交配偏好如何影响杂交后代的产生，将确定栖息地变化是否与杂交有关，并将比较杂交和非杂交个体之间的生存率和繁殖成功率。 本科生和高级高中生将协助现场和实验室数据收集，包括农村和当地的美洲原住民学生谁是他们的家庭成员的第一次上大学。
