Population structure at two geographic scales in the burrowing crustacean Callichirus islagrande (Decapoda, Thalassinidea): historical and contemporary barriers to planktonic dispersal.

Abstract excerpt

There has been much recent interest in the extent to which marine planktonic larvae connect local populations demographically and genetically. Uncertainties about the true extent of larval dispersal have impeded our understanding of the ecology and evolution of marine species as well as our attempts to effectively manage marine populations. Because direct measurements of larval movements are difficult, genetic...
