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，这可能导致基因流模式的不同。 基因流的差异可能会影响物种微位点适应的潜力。 因此，具有对比生殖模式的物种被包括在这项局部分化的研究中。 将评估孢子、配子和无性繁殖体的基因流传播模式。 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的教师研究提供了资金。 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，并增加我们对研究很少但普遍存在的生物体的生殖生态学的了解。
