Abstract

Dominance-diversity relations in epiphytic, epilithic and epigenous bryophyte communities were studied based upon differences in dry weight of component species. Three types of dominance-diversity curves were distinguished : straight line, L-shaped and sigmoid. The curves change in this respective order from communities composed of small numbers of species, life-forms and strata to those composed of large numbers of these characters.
