The rarefaction method proposed by Sanders (1968) to allow one to compare the diversity of samples composed of different numbers of individuals and species is compared with the results that would be obtained if smaller random samples were taken from a universe defined by the observed sample. The rarefaction technique overestimates the number of species that would be expected by sampling.

Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as within regions. Among other factors, the diversity of all living things depends on temperature, precipitation, altitude, soils, geography and the presence of other species.The study of the spatial distribution of organisms, species and ecosystems, is the science of biogeography.
