Webb23 okt. 2024 · Plug-in estimates of many alpha diversity indices (including richness and Shannon diversity) are negatively biased for the environment's alpha diversity parameter, that is, they underestimate the true alpha diversity (Lande, 1996). Attempting to address this problem using rarefaction actually induces more bias. Webbprofound and useful of all diversity indices, but its value gives the uncertainty rather than the diversity.
