Rarity is common and widespread. As early as 1859 Charles Darwin wrote that ‘rarity is the attribute of a vast number of species in all classes, in all countries’. All species are rare somewhere, and most species are rare toward the periphery of their ranges (Hanski, 1982; Brown, 1984; Hanski et al., 1993). The majority of species comprising local biotas are rare (Preston, 1948; Hubbell, 1979). Indeed, the rarity of most species gave rise to a major school of ecological thought, which asserted that populations were typically regulated by density-independent factors acting at low population densities rather than by density-dependent factors, such as competition, whose effects should be most strongly felt at high population densities (Andrewartha and Birch, 1954).
