Hi all, i using vegan in R to analysis the biodiversity data, but the value result of Eveness index and Simpson index not relatively different, i can say it's same a little. Example value this evenness is 0.265 and the simpson is 0.243. Until now, I know the simpson/dominance index is opposite with eveness, if Evenness index near to 1 , the simpson/dominance index near to 0, but not exactly thus.
