Simpson's diversity index biology

WebbTo determine the diversity value for a given habitat, we must first calculate the number and proportion of species in the habitat and then enter those numbers into the equation provided above. Habitat A: Habitat A has two species, blue insects and red insects. There are 10 total insects in this habitat, 1 of which is blue and 9 of which are red. WebbTo answer this question, the Simpsons Diversity Index (SDI) provides a value between 0 and 1 for each sample, indicating their level of species diversity, which you can then compare. If an ecosystem has a SDI of 1 this means it has infinite diversity. Whilst a SDI of 0 means it has zero diversity (i.e. only one species).
