WebbSimpson’s index DS is similarity index (the higher the value the lower in diversity). While Shannon index is combining evenness and richness and less weighted on dominant species. Both indexes are more reflective in nature and can predict the environment health. Therefore, it may be good to have one of those biodiversity indexes to be used ...
