distinct (ED) species, and (f) endemic species. Geographic coordinate system is in NAD83, projected coordinate system is lambert equal area.

(DOCX) S3 Fig. Spatial congruency (measured as percent overlap) of shark hotspots between three species richness measures: Total species, evolutionary distinct (ED) species, and endemic species. Congruency is represented at two levels of hotspot definition: (a) 2.5% and (b) 10%, and three levels of spatial resolution: 1˚, 4˚, and 8˚. The subset of threatened species only are indicated in red. (DOCX) S4 Fig. Biodiversity hotspots derived for three measures of species richness. General rich- ness hotspots of (a) total species, (b) evolutionarily distinct (ED) species, and (c) endemic spe- cies. (d-f) Threatened subset of richness hotspots for (d) total species, (e) evolutionarily distinct (ED) species, and (f) endemic species. For each species richness measures, hotspots are defined as the richest 2.5% of grid all cells. Geographic coordinate system is in NAD83, pro- jected coordinate system is lambert equal area, grid cell resolution is 1˚.

(DOCX) S5 Fig. Biodiversity hotspots derived for three measures of species richness. General rich-

ness hotspots of (a) total species, (b) evolutionarily distinct (ED) species, and (c) endemic spe- cies. (d-f) Threatened subset of richness hotspots for (d) total species, (e) evolutionarily distinct (ED) species, and (f) endemic species. For each species richness measures, hotspots are defined as the richest 10% of grid cells.

(DOCX) S6 Fig. Biodiversity hotspots derived for three measures of species richness. General rich- ness hotspots of (a) total species, (b) evolutionarily distinct (ED) species, and (c) endemic spe- cies. (d-f) Threatened subset of richness hotspots for (d) total species, (e) evolutionarily distinct (ED) species, and (f) endemic species. For each species richness measures, hotspots are defined as the richest 2.5% of grid cells. Geographic coordinate system is in NAD83, projected coordinate system is lambert equal area, grid cell resolution is 4˚.

(DOCX) S7 Fig. Biodiversity hotspots derived for three measures of species richness. General rich- ness hotspots of (a) total species, (b) evolutionarily distinct (ED) species, and (c) endemic spe-

cies. (d-f) Threatened subset of richness hotspots for (d) total species, (e) evolutionarily distinct (ED) species, and (f) endemic species. For each species richness measures, hotspots are defined as the richest 5% of grid cells.
