explane species area relationship more detail

Dear Student,

Alexander von Humboldt observed that biodiversity increases with increase in explored area. This relationship can be given by,

log S = log C + Z log A

Where,

S = Species richness

A = Area

Z = Slope of the line (regression co-efficient)

C = Y-intercept

Value of Z is found to lie in the range of 0.1 to 0.2 for comparatively smaller areas such as countries while for very large areas such as entire continents, the slope of the line is much steeper with Z value lying from 0.6 to 1.2.

 Hope this helps, you will be learning more about species-area relationship in your higher grades if you chose ecology as a subject of learning.

All the best!!
