    Gulf Coast vicariance shapes phylogeographic history of a North American freshwater mussel species complex

    AimFreshwater mussels share habitat and are parasites of freshwater fishes during the larval life stage. Therefore, models of fish biogeography may also explain the historical biogeography of freshwater mussels. We tested this assumption using predictions of three biogeographic models constructed for northern Gulf of Mexico drainages on a...
