Abstract

Five methods of computing species richness in community are discussed using the example of a well-studied macrophytic taxocoen: (1) fitting an ogive for lognormal distribution; (2) model fitting of a rank curve for this distribution; (3) iterative computation of statistical moments using Hald’s method; (4) computation of these moments by explicit functions; and (5) model fitting of a “species-area” curve. According to the repeatability of results and simplicity of computing, the best method is the computation of statistical moments by explicit functions. The degree of our knowledge about a particular community could be considered as the ratio of the number of actually distinguished species to the greatest expected number.
