Q. Calculate the species diversity, species richness and species evenness of the birds of the following two wetlands
SPECIES DIVERSITY
Shanon Weiner Indexor
Species Richness
Where S = Number of species present in communityN = Number of Individuals in community
Species richness of Wetland 1
Species richness of Wetland 2
Species Evenness
Where C = Species Evenness = Shanon Weiner IndexS = Number of species
SIMILARITY & DISSIMILARITY INDEX
SIMILARITY INDEXWhereS = Similarity IndexC = Common species to both samplesA = Number of species in sample AB = Number of species in sample B
DISSIMILARITY INDEXDissimilarity Index = 1 - S
SOLUTIONWe have found thatNumber of species in Habitat A = 5Number of species in Habitat B = 6Common species to A and B = 3
CALCULATIONSIMILARITY INDEX
DISSIMILARITY INDEXDissimilarity Index = 1 - S = 1 0.545 = 0.455
