Hitchhiking the high seas: Global genomics of rafting crabs.

ABSTRACT: Population differentiation and diversification depend in large part on the ability and propensity of organisms to successfully disperse. However, our understanding of these processes in organisms with high dispersal ability is biased by the limited genetic resolution offered by traditional genotypic markers. Many neustonic animals disperse not only as pelagic larvae, but also as juveniles and adults while drifting or rafting at the surface of the open ocean. In theory, the heightened dispersal ability of these animals should limit opportunities for species diversification and population differentiation. To test these predictions, we used next-generation sequencing of genomewide restriction-site-associated DNA tags (RADseq) and traditional mitochondrial DNA sequencing, to investigate the sp
