The two phenomena involved [“diversity of individual stands, and relative differentiation of vegetation patterns along topographic moisture gradients”] suggest the need for distinguishing three aspects or levels of species-diversity in natural comnmunities: […] (2) The extent of change of community composition, or degree of community differentiation, in relation to a complex-gradient of environment, or a pattern of environments, which may be designated secondary or “beta” diversity.
