WebVariation in fish assemblage structure was examined in different rivers of the Seine Basin. Factor analysis was used to identify similarities among samples and species, and to show ichtyological changes along an upstream-downstream gradient. Fish species richness was correlated with catchment area, distance from the source and number of individuals. … WebSpecies richness increases with habitat area and heterogeneity. The increase in species richness (S) with habitat area ( A) is often predicted by the equation S = constant × Az. The z value depends on the organisms, the spatial range of the study, and the habitats, and there is no single mechanism that can account for the variability of z.
