Phylogeography and marine retention

A number of studies now point to the association of patterns of phylogeography with discontinuities in coastal current patterns. If such phylogeographic patterns are indicative of populations that retain local diversity, as has been predicted by recent modelling, such results may be of use in marine reserve planning. Here we show that there is a distributional correlation on the Pacific coast of North America between marine reserve placement and phylogeographic patterns. A number of factors could contribute to this correlation, but its existence suggests the utility of genetic studies in marine conservation planning.
