• Sommario/riassunto: A synthesis of present understanding of the structure of the geographic ranges of species, which is a core issue in ecology and biogeography with implications for many of the environmental issues presently facing humankind. - ;No species occurs everywhere. Indeed, the majority are absent from most places, and where they do occur they are usually quite rare. Gaston discusses the structure of these distributions - the structure of the geographic ranges of species. Gaston is particularly concerned with the factors that determine the limits to a species' geographic range, how the sizes of those ra
