This dissertation explores the systematics, biogeography, and genomics of the gooseneck barnacle Pollicipes elegans, a marine crustacean of the tropical Eastern Pacific. In Chapter 1, I provide a broad framework for my research by introducing and focusing on the long-‐standing debate of the mechanisms behind the latitudinal gradient in species diversity, which provided the initial motivation for using Pollicipes elegans as a model system to study the mechanisms leading to genetic differentiation and speciation in tropical regions. In Chapter 2, I examine the genetic structure, infer patterns of connectivity across the warm tropical waters of the eastern Pacific, and reconstruct …
