coefficient of faunal similarity (CFS)

What is coefficient of faunal similarity (CFS)?

coefficient of faunal similarity (CFS) meaning The CFS compares the fauna of one area with that of another. CFS = 2C/(a+b), where C = the number of species in common between two areas, a = the number of species in the first area, and b = the number of species in the second area. The higher the CFS, the greater the resemblance
