Abstract:

The article describes how to make use of the method of estimating the degree of coincidence of two or more species in samples by comparison of the most probable number, in the given series, of cases in which both species concur in the sample, with the actual number of such concurrences (E d m o n d s o n, 1944, K a j a k A., 1957). The author demonstrates that this method may be applied where each species occurs in about 30-40% of the samples. Where the percentage of complete samples is different, analysis of the concurrence of species in the samples should be preceded by a mathematical manipulation reducing the series examined to the required form. An example of this manipulation is given. The author points out that all estimates of concurrence of species in the field should be related to the corresponding space. Categories of size of the area of samples with differing ecological sense are given as examples.
