What is the Shannon Wiener diversity index?

The most common measures of biodiversity are species richness, Simpson's index and Shannon-Wiener index. Species Richness. This is the simplest of all the measures of species diversity. All you do is count of the number of species found in a community (e.g., the number of the species found on a biofilm plate).

Similarly, what does the Shannon diversity index mean?

Methods: The Shannon diversity index (H) is another index that is commonly used to characterize species diversity in a community. Like Simpson's index, Shannon's index accounts for both abundance and evenness of the species present. Equitability assumes a value between 0 and 1 with 1 being complete evenness.

What is the diversity index?

A diversity index is a quantitative measure that reflects how many different types (such as species) there are in a dataset (a community), and simultaneously takes into account how evenly the basic entities (such as individuals) are distributed among those types.
