2 Figure 1 Planet Earth, Showing Locations of Islands that Were Sampled across the Western and Central Pacific Ocean Local abundances of coral (circles) and fishes (triangles) were measured at multiple sites and habitats (reef flat, crest, and slope) on each island. Also shown are contours of species richness for corals [18], indicating the steep latitudinal gradient in biodiversity across the Pacific Ocean.

3 Figure 2 Relationship between Geographic Range and Mean Local Abundance for Species of Corals and Reef Fishes Local abundance is measured as percentage coral cover (A and B) and density of reef fishes (C and D). Range is calculated as the total area within a species geographic boundary, excluding land (A and C), and as the summed area of reefs encompassed by each range boundary (B and D). Data points represent individual species (n = 323 species of corals and n = 115 species of labrid fishes). The spread of ranges along the x axes indicates the arbitrary distinction between endemics (to the left) and pandemics (to the right). See also Figures S1–S4 and Tables S1 and S2.

4 Figure 3 Rank Abundance Curves for Species in Multiple Regions across the Pacific Biodiversity Gradient Note the large span of abundances of individual species of corals (A) and fishes (B) and biogeographic shifts in the spectrum of abundances along the Pacific biodiversity gradient.
