Webgraphic theory (MacArthur and Wilson 1967) to the design of wildlife refuges (references in Simberloff 1982), the most frequent specific recommendation is that a single large refuge will maintain more species than two or more small ones with total area equal to that of the single large one (Wilson and Willis 1975; Diamond and May 1976). Web27 apr. 2016 · Despite the successes of their theory, MacArthur & Wilson [ 1] discovered empirical examples where the theory's predictions broke down. In particular, they noted that archipelagos exhibit unusual species–area relationships (SARs): below a threshold island area, island species richness apparently varies independently of area.
