Question
Given below is an equation describing the Species-Area relationship between species richness and area for a wide variety of taxa as angiosperm plants, birds, bats etc. S = CAz
- Give a graphical representation of the given equation showing Species-Area relationship.
- What does 'S' represent in the given equation?
- What is the value of 'Z' (regression coefficient) for frugivorous birds and mammals in the tropical forests of different continents?

Solution
- The given equation's graphical representation of the relationship between species and area is as follows:
- The species richness is represented by S in the given equation.
- The regression coefficient Z is the slope of the line. The slope is found to be 1.15 for frugivorous (fruit-eating) birds and mammals in tropical woods on various continents.
