Dispersal of planktonic larvae can create connections between geographically separated adult populations of benthic marine animals. How geographic context and life history traits affect these connections is largely unresolved. We use data from genetic studies (species level F ) of benthic teleost fishes combined with linear models to evaluate the importance of transitions between biogeographic regions, geographic distance, egg type (benthic or pelagic eggs), pelagic larval duration (PLD), and type of genetic marker as factors affecting differentiation within species. We find that transitions between biogeographic regions and egg type are significant and consistent contributors to population ..View full abstract
