Data from: High gene flow across large geographic scales reduces extinction risk for a highly specialised coral feeding butterflyfish

Rebecca J. Lawton, Vanessa Messmer, Morgan S. Pratchett & Line K. Bay
The vulnerability of ecologically specialised species to environmental fluctuations has been well documented. However, population genetic structure can influence vulnerability to environmental change and recent studies have indicated that specialised species may have lower genetic diversity and greater population structuring compared to their generalist counterparts. To examine whether there were differences in population genetic structure between a dietary specialist (Chaetodon trifascialis) and a dietary generalist (C. lunulatus) we compared the demographic history and levels of...

Understanding patterns of connectivity among populations of marine organisms is essential for the development of realistic, spatially explicit models of population dynamics. Two approaches, theoretical and empirical population genetic models, have been used to estimate levels of evolutionary connectivity among marine populations but rarely have their potentially-complementary insights been combined. Here, a spatially-realistic Lagrangian model of larval dispersal and a theoretical genetic model are integrated with the most extensive study of gene flow in a...
