Terrestrial species adapted to sea dispersal: Differences in propagule dispersal of two Caribbean mangroves.

A central goal of comparative phylogeography is to understand how species-specific traits interact with geomorphological history to govern the geographic distribution of genetic variation within species. One key biotic trait with an immense impact on the spatial patterns of intraspecific genetic differentiation is dispersal. Here, we quantify how species-specific traits directly related to dispersal affect genetic variation in terrestrial organisms with adaptations for dispersal by sea, not land-the mangroves of the Caribbean.
