Species Richness & Simpson's Index:
3 Species |
6 Species
Species Richness & Shannon-Wiener Index:
3 Species |
6 Species
Using the species counts, fill out the following tables to calculate values for species richness, the Shannon-Wiener index and Evenness.
Some Notation:
Species Richness: S - the number of different species found on plate.
P_{i} - the number of a given species divided by the total number of organisms observed. When you compute the probability for each species, please use decimal percent (e.g., use 0.25 and not 25% or 1/4).
Shannon-Weiner index: H = -sum(P_{i}log[P_{i}]) (While you may use any base, the natural log is commonly used)
