Corrections to the indices of community dissimilarity based on species diversity measures

Summary A number of indices of community dissimilarity based on the species diversity measures have been proposed during the last three decades (Margalef 1956, 1957; Kohn 1959; MacArthur 1965; Horn 1966; Glowaciski and Järvinen 1975; Järvinen and Väisänen 1976). Each of them is measuring the wrong quantity if the value of diversity in a particular sample is higher than in a pooled sample. Simple corrections are suggested to avoid this shortcoming.
