Question

What are the different methods to determine the diversity of species?

1) Species richness (S)
2) Species evenness (relative species abundance)
3) Percentage cover
4) Percentage frequency
5) Simpson's diversity index (D or SDI)

Answer 1

Different methods to determine the diversity of species include species richness, species evenness, percentage cover, percentage frequency, and Simpson's diversity index.

Step-by-step explanation:

There are several methods to determine the diversity of species:

1. Species richness (S): Species richness is a count of the number of different species in a defined area. It is a measure of the total number of species present.
2. Species evenness (relative species abundance): Species evenness quantifies the distribution of individuals among different species. It measures how evenly the individuals are distributed among the different species.
3. Percentage cover: Percentage cover is a measure of the amount of ground covered by a particular species in a defined area.
4. Percentage frequency: Percentage frequency is a measure of the frequency of occurrence of a particular species in a defined area.
5. Simpson's diversity index (D or SDI): Simpson's diversity index takes into account both species richness and species evenness and provides a single value that represents the diversity of a community.
