  abstract = {{W}e report a novel pattern in species richness, complementary to the well-known species-area relationship. {W}e show that, as sample area increases, the variation in relative richness decreases among otherwise comparable spatial units. {T}his pattern holds for southern {A}frican birds, {F}rench birds, {C}ape {P}roteaceae and the trees of {B}arro {C}olorado {I}sland. {W}e propose a scale-free method for quantifying this pattern by measuring the multifractal intensity of species richness, which is the multi-scale tendency of adjacent patches with the same area to differ in richness. {B}y this measure, spatial variability is strongest for {C}ape {P}roteaceae and weakest for {B}arro {C}olorado {I}sland trees. {O}ur results have implications for area-dependent estimates of species-richness, for example in reserve planning and in simulation-based studies. {T}hey imply that such estimates are most accurate for large areas, and will be subject to substantial uncertainty when the multifractal intensity is high and the area is small. {F}or comparative purposes, multifractal intensity may be used as a supplement or as an alternative to mean richness, as well as for other ecological densities, such as biomass distribution and local abundance.},
