Sampling locations of Acropora palmata (A) and A. cervicornis (B). Both species are dominant reef-building corals of Caribbean and northwestern Atlantic reefs and are the only representative species of the genus Acropora in the region. Letter notation on the map indicates the geographic origin of A. palmata genome genet at Horseshoe Reef (HSR) and A. cervicornis genome genet near Grassy Key (GKR). Photos by IBB
