Webb1 jan. 2012 · Robert Whittaker (1920–1980) was one of the most influential modern ecologists and made important contributions to a wide range of fields ( Westman and Peet 1985 ). Although the five-kingdom system was only a minor part of his work, it reflected two of Whittaker's fundamental interests. In ecology, beta diversity (β-diversity or true beta diversity) is the ratio between regional and local species diversity. The term was introduced by R. H. Whittaker together with the terms alpha diversity (α-diversity) and gamma diversity (γ-diversity). The idea was that the total species diversity in a landscape (γ) is determined by two different things, the mean species diversity at the local level (α) and the differentiation among local sites (β). Other formulations for beta diversity includ… jonathan hemphill zebulon police chief
