description: simpsons diversity index (1/D) calculated for all tcrmp transects. D considers both species richness and evenness. D = sum_{i=1}^{S} p_i^2 , where p_i is the proportion of individuals of species i and s is the number of species. A higher value of D indicates lower diversity, so the inverse or complementary value 1/D was calculated and used to indicate diversity.
