Body size and species richness and Nicoletto, 1991). This mechanism likely contributes to the shift in body size-species richness distribution observed between continental and local scales. Recently, the metabolic theory of ecology has been used to explain macroecological patterns. According to May (1978) there is equal energy flow through all size classes of interacting organisms. This has implications for the number of individuals in each size class and potentially the number of species as well. May (1978) was the first to describe a mathematical equation that could be used to explain the right hand side of the body size-species richness pattern . His equation states
