The number of species in an area increases with the size of the area up to a limit.

Vedclass · Answer

(A) The species-area relationship,proposed by Alexander von Humboldt,states that within a region,the species richness increases with increasing explored area,but only up to a limit.This relationship is mathematically expressed as $\log S = \log C + Z \log A$,where $S$ is species richness,$A$ is area,$Z$ is the slope of the line (regression coefficient),and $C$ is the $Y$-intercept.As the area increases,the number of species increases because more habitats and resources become available to support a greater variety of organisms.

What is the significance of the slope of regression in a species-area relationship?

According to the hypothesis proposed by environmental biologists,a relatively constant environment in the tropics promotes:

$A$ species-area curve is drawn by plotting the number of species against the area. Why is the slope of the regression line steeper when a very large area (like an entire continent) is considered compared to smaller areas?
