Question

For smaller areas, what is the typical range of the Z value (slope) in the species-area relationship?

Options

• 0.6 to 1.2

• 0.1 to 0.2

• 1.5 to 2.0

• 2.5 to 3.0

Answer 1

For smaller areas, the Z value (slope of the regression line) in the species-area relationship typically ranges from 0.1 to 0.2. This indicates a gentler slope, meaning species richness increases more gradually with area in smaller regions compared to larger geographic areas.
