Question

What does the variable Z represent in the species-area relationship formula log S = log C + Z log A?

Options

• A constant value unrelated to the relationship

• Species richness

• The slope of the line or regression coefficient

• The area being explored

Answer 1

In the species-area formula log S = log C + Z log A, Z represents the slope of the line or regression coefficient. The value of Z indicates how steeply species richness increases with area and varies depending on the size of the area being studied.
