Question

Study the graphical representation of Species richness - Area relationship given below and answer the questions that follow:

a. What do S, C, Z and A represent in the given graph?
b. What will be the range value of Z line if we analyse the species-area relationship among very large areas like entire continent?

✓

Answer

a. S is the species richness
A is the area
C is a constant
Z is the regression constant.
b. If the species-area relationships are analysed among very large areas like the entire continents, the value of Z, i.e., slope of line lies in the range of 0.1 to 0.2.
