Explanation

Alpha diversity (within community diversity) is species diversity in a given community or habitat. `alpha`-diversity is dependent upon species richness and species eveness/equitability. There is a lot of competition, adjustments and interrelationship amongst members of the same community. The number of species per unit area is called species richness. Number is individuals of different species represents species evenness or species equitability.
