Alpha and beta diversity showed minor variation between samples from the three primary sampling sites on Isabela Island: Caleta Iguana (CI), Puerto Pajas (PP), and Marielas (M). Observed richness and Simpson’s Index were similar between sites (A, B), but Shannon Diversity Index significantly differed (C). Principal Coordinates Analysis illustrated slight clustering between locations (D). Sample sites are shown along the western coast of Isabela Island, with the Galapagos Archipelago in the map inset (E).
