Alexander von Humboldt, a German naturalist and geographer, proposed the species - area relationships during his extensive explorations in the South American jungles. He observed that, within a region, species richness increased with increasing explored area, but upto a certain limit.
The relationship between species richness and area can be given by the equation
$S=C{A}^z$
where S - Species richness
Z - Slope of line (regression coefficient)
C - Y-intercept
A - Area
