Question

For very large areas such as entire continents, what is the typical range of the Z value in the species-area relationship?

Options

• 1.5 to 2.0

• 0.1 to 0.2

• 0.6 to 1.2

• 0.05 to 0.1

Answer 1

For very large areas such as entire continents, the Z value becomes much steeper, ranging from 0.6 to 1.2. This steeper slope indicates that species richness increases more rapidly with area at continental scales, demonstrating that larger geographic regions encompass much greater species diversity.
