Latitudinal distribution in species richness using GAMs (the effect of latitude adjusting for shelf area in each 5° latitudinal band) (SI Appendix, Table S4) in (A) all species, (B) pelagic, and (C) benthic species in three time periods: 1955 to 1974 (green), 1975 to 1994 (purple), and 1995 to 2015 (red). Shaded regions represent 95% confidence envelopes for models fit to each of the periods, with shades (from green to red) reflecting progression of time periods from older to more recent.
