Mary Jones, Richard Fosbery, Dennis Taylor and, Jennifer Gregory Solutions for Chapter: Classification Biodiversity and Conversation, Exercise 11: Question

In a survey of trees in a dry tropical forest. Some students identified five tree species (A to E). They counted the numbers of trees in an area 100m * 1oo m. Their results are as follows:

A 56      B 48    C 12      D 6      E 3

Calculate the Simpson’s index for the trees within the area sampled.

Explain the advantage of using Simpson’s index of diversity rather than a species list as a way to represent the biodiversity of an area.

The Simpson’s index of diversity for the vegetation in an area of open grassland was 0.8 for a similar sized area of vegetation beneath some conifer trees it was 0.2. What do you conclude from these results.
