Bryophytes exhibit a wide range of breeding systems which may result in divergent patterns of gene flow. Differences in gene flow may influence the species potential for microsite adaptation. Thus, species of contrasting reproductive mode are included in this study of local differentiation. Patterns of gene flow dispersal of spores, gametes and asexual propagules will be assessed. These studies are based on 3 years of field experiments and laboratory analysis. The proposal offers significant opportunities for research collaboration for undergraduates and provides funds for faculty research at an institution primarily devoted to teaching. The proposed research will enhance our understanding of the role of selection and environmental heterogeneity in the maintenance of genetic diversity, and add to our knowledge of the reproductive ecology of a little-studied, but ubiquitous group of organisms.

苔藓植物表现出广泛的育种系统，可能导致基因流动的不同模式。 基因流量的差异可能会影响微材料适应的物种潜力。 因此，本局部分化的研究包括对比鲜明的生殖模式的种类。 将评估孢子，配子和无性繁殖体的基因流量分散的模式。 这些研究基于3年的现场实验和实验室分析。 该提案为本科生提供了重要的研究合作机会，并为主要致力于教学的机构提供了教师研究的资金。 拟议的研究将增强我们对选择和环境异质性在维持遗传多样性中的作用的理解，并增加了我们对一些有点研究但无处不在的生物体生殖生态学的了解。
