Abstract
Great speciators are species present on multiple islands that have many subspecies, many of which are single island endemics. This pattern is paradoxical because to colonize islands a good overwater dispersal ability is required, but divergence often requires limited gene flow, suggesting limits to dispersal. To resolve the ‘paradox of the great speciators’, many authors suggest that strong selection against dispersal ability after island colonization may shift populations to become less dispersive. We tested whether candidate genes for personality traits and migration were associated with population age and dispersal ability in the silvereye, a great speciator from the South Pacific. We found that old populations where individuals have lower dispersal ability had shorter microsatellite alleles at the CREB1 gene. We also found that, in a partial migrant population, migrant individuals had more repeats at CLOCK compared to resident individuals from the same population.
