H'=Shannon-Weiner Diversity Index, where absolute diversity=1.00
J'=Evenness or relative Diversity (H'/Hmax), where absolute evenness=1.00
1-J'=Dominance or heterogeneity (where absolute dominance=0.00)
CC= Community Similarity [CC= C/(S1+S2-C)], where C=# species common to both, S1=species in community 1, and s2=# species in community2
