Question

The exponent z of the species-area curve measured at continental scales is?

Answer 1

Explanation:

A species-area curve is the relationship between the area of a habitat and the number of species found within that area. So: z = 0.324 and log c = 0.493 or, equivalently, c = 10 0.493 = 3.113. Thus, the power model is: S=cAz = 3.113A0. 324 where A is measured in square miles.
