Summary: A group of parametric factors of generic and taxonomic diversity , based on the estimations of "effective number of species" or Hill numbers is considered. The difference of this group from other diversity indices based on Shannon formula or other expressions is discussed. The way of partitioning general γ-diversity into α- and β-components is demonstrated. The computation procedure of taxonomic distances matrix based on the phylogenetic tree of Linnaean systematics is described. Dynamics of indices variability of generic and taxonomic diversity along a longitudinal waterway profile on the example of macrobenthos communities of the middle-size flatland river Sok (inflow of the Saratov water basin) is considered. The algorithms of statistical significance control of differences between diversity indices in comparing two or more groups of the habitat based on randomization procedures are described.
