Abstract: In order to assess and compare sample completeness and alpha diversity of samples, Chao et al. (2020) proposed a 4-step-workflow. It is based on their extensive earlier works (e.g., Chao et al. 2014) which make use of the now widely accepted concept of Hill numbers, also known as effective number of equally abundant species qD (Hill 1973, Chao et al. 2014). Here, q denotes the diversity order of a Hill number and determines its sensitivity to species’ relative abundances or frequencies (in case of incidence data, i.e., species presence /absen...
