Speciation in coral reef fishes


Covering less than 0.1% of the ocean’s surface, coral reefs harbor ~5,000 fish species, or about a third of all marine fishes. Interestingly, very few strong biogeographic barriers exist in the oceans, and most coral reef fishes have a widely dispersing pelagic larval stage. This observation creates a paradox of high species diversity combined with apparently few opportunities for the commonly accepted allopatric speciation model. I will present a summary of current hypotheses to explain this paradox, as well as phylogeographic and phylogenetic data for several groups reef fishes and talk a bit about how next generation sequencing promises to revolutionize studies in this field.
