Figure 2 Variation in the species richness of marine bivalves
across a latitudinal gradient on the eastern coastline of Australia,
estimated using the corrected jackknife equation of Alroy (2020). Panels
show different subsets of an OBIS dataset – the full dataset
(a ), inclusive of observational data (b ), and with
cells matched to field data (c ). Blue points in each panel show
estimates based on field data for comparison. All y-axes are logged for
clarity.
