説明
To examine seasonal change of species diversity, several species diversity indices are calculated, in phototactic coleopterous community on Mt. Iwawaki, Osaka. Average species diversity (H') and relative species diversity (e^H'/S) both in sample, and their expectations in population (E(H'/N) and e^<E (H'/N>/Q) are compared to each other. Average species diversity is divided into two factors, viz, "species richness" measured by S in sample and Q in populations, and "equitability" measured by their relative diversity indices. In connection with the method estimating the total number of species in biological universe (Q), a problem employing "Preston' s lognormal distribution model "on number of species and number of indiviauals in population is discussed. It is suggested that the estimated values of Q lead to noticeable error in some times. It seems to be more practical to use the sample values obtained by standardization of sampling method, comparing with the population values estimated by the model.
