Webb1 aug. 2016 · Shannon–Wiener index ( H ′) primarily reflects evenness relative to richness (≥3:1). H ′ has unique richness-based curvilinear relationships with evenness. • H ′ redefined as a logarithm-weighted measure of evenness at a given level of richness. • H ′-derived effective species ( D) are biased relative to D = richness (>7) × evenness. • http://loujost.com/Statistics%20and%20Physics/Diversity%20and%20Similarity/Diversity%20of%20a%20single%20community.htm
