Islands within an island: origins, diversification, and endemism of the montane flora of Hispaniola

Project summary:

To provide insight into the processes contributing to exceptional endemism on insular mountains, I will study the evolutionary history of five species-rich vascular plant families on Hispaniola. Using a phylogenomic framework, I will investigate how immigration and in-situ radiations contribute to patterns of diversity and endemism observed on the island.
