On size and area: Patterns of mammalian body size extremes
... Because species richness and area are positively correlated (MacArthur and Wilson, 1967), larger landmasses have a higher probability of picking up species with extreme values of body size. In statistical terms, the pattern presented in Fig. 1 is qualitatively predicted by the theory of order statis ...
