  • The term beta diversity was introduced by R.H. Whittaker in 1960. He defined it as “the extent of change in community composition or difference in species composition in different sites either local or entire landscape".
  • Therefore, beta diversity is the diversity operating between communities. Beta diversity is the connecting link between regional and local diversity. It shows the difference in species among the sites.

So, the correct answer is option B.
