1.     Dominance Measure of diversity whick takes into account both richness and evenness of species. It is often used to quantify the biodiversity of a habitat. A community dominated by one or two species is considered to be less diverse than one in which several different species have a similar abundance. Simpson's Diversity Index is a measure of diversity which takes into account the number of species present, as well as the relative abundance of each species. As species richness and evenness increase, so diversity increases. 2.     Eveness Species evenness refers to how close in numbers each species in an environment is mathematically it is defined as a diversity index , a measure of biodiversity which quantifies how equal the community is numericall. 3.     Species richnes Richness R simply quantifies how many different types the dataset of interest contains. For example, species richness (usually noted S ) of a dataset is the number of different
