SUPPLEMENTARY MATERIAL 1. Marine biodiversity inventory of (I) Macroalgae (excluding most crustose coralline algae), (II) Marine Plants, (III) Invertebrates, and (IV) Fishes from 5 intertidal and subtidal locations (BC = Blue Cavern, BFC = Big Fisherman’s Cove, HR = Habitat Reef, IP = Intake Pipes, and PC = Pumpernickel Cove) in Blue Cavern Onshore State Marine Conservation Area off Santa Catalina Island, California. Scientific names preceded by an equals sign in parentheses indicate the species name when the species was first reported. Values in parentheses specify the number of species recorded for each taxonomic group. Taxa are organized alphabetically by phylum and class (columns organized top to bottom, left to right). Table footnotes (see page 25) are indicated by superscripted letters. 1 Taxa Location Reference I.
