Dissertations
Genetic structure within and among plant populations is a critical component of plant biodiversity, informing local adaptation, conservation, and incipient speciation. However, its drivers remain poorly understood, especially across different spatial scales. In my dissertation I examined factors that affect plant population genetic structure at global, regional, and local scales. At the global scale, I performed a literature review of population genetic differentiation (FST) in seed plants based on a 337-species dataset with data on FST and species traits. Using phylogenetic multiple regressions, I found that FST is higher for tropical, mixed-mating, non-woody species pollinated by …
