List of equations used for analyzing biodiversity indices of Chunati Wildlife Sanctuary

Sl NoBiodiversity indicesFormulasReferences
1Species diversity index (SDi)SDi = S/NOdum (1971) 
2Shannon–Wiener's diversity index (H)H = −∑i=0nPi ln PiMichael (1990)
3Shannon's maximum richness index (Hmax)Hmax = Ln(S)Kent and Coker (1992) 
4Margalef's species richness index (R)R = (S-1)/Ln(N)Margalef (1958) 
5Simpson's diversity index (D)D=∑i=1npi2Magurran (1988) 
6Dominance of Simpson's index (D')D' = 1-DMagurran (1988) 
7Species (Pielou's) evenness index (E)E = HLn(S)Pielou (1966) 

Note(s): H= Shannon–Wiener's diversity index; N = total no. of individuals of all the species; Pi = number of individuals of ith species/total number of individuals; S = total number of species; n is the number of individuals of each species
