Figure S2 from Metabolic rates, climate and macroevolution: a case study using Neogene molluscs

Sample-size-based rarefaction (solid line) and extrapolation (dashed lines) of Western Atlantic bivalve and gastropod species richness (q= 0) for each of five separate time bins (early Pliocene, late Pliocene, early Pleistocene, middle Pleistocene, late Pleistocene). Reference sample for each sampling interval is indicated by a solid dot. Shaded areas equal rarefaction confidence intervals. For a fixed sample size, where confidence intervals for Hill number rarefaction/extrapolation do not overlap, significant difference (at a level of 5%) is guaranteed.
