Emergent patterns of population genetic structure for a coral reef community
What shapes variation in genetic structure within a community of codistributed species is a central but difficult question for the field of population genetics. With a focus on the isolated coral reef ecosystem of the Hawaiian Archipelago, we assessed how life history traits influence population genetic structure for 35 reef animals. Despite the archipelago’s stepping stone configuration, isolation by distance was the least common type of genetic structure, detected in four species. Regional structuring (i.e.
