There are better ways to quantify biodiversity than coverage-based rarefaction – in particular, by fitting the geometric Weibull distribution and extrapolating. GW outperforms CBR according to four different empirical tests. New paper in Oikos.

Coverage‐based rarefaction fails to quantify relative species richness
Coverage-based rarefaction (CBR) is a high-profile tool for assessing biodiversity that provides relative species richness estimates by leveraging the Good-Turing index u to interpolate. In contrast ...
