For a rectangular sample area the species-area relationship follows the pattern, with some simplification, $S=c|A^{\beta}+a|^z$, where $S$ is the number of species in the area of size $A$ and $a, c, z$, and $\beta$ are constants with $z<1$ and $\beta\leq1$.

Improvement on Extrapolation of Species Abundance Distribution Across Scales from Moments Across Scales

The almost linear pattern of the log transformation of raw moments across scales allow us to extrapolate species abundance distribution for larger areas.
