Alpha Diversity = richness and evenness of individuals within a habitat unit. Biodiversity is usually plotted as taxonomic richness of a geographic area, with some reference to a temporal scale. A diversity index is a quantitative measure that reflects how many different types there are in a dataset and that can simultaneously take into account the phylogenetic relations among the individuals distributed among those types, such as richness, divergence or evenness.These indices are statistical representations of biodiversity in different aspects.

Do Now: What do you think the term invasive species mean? - Ex Horse Donkey Mule. β diversity is also treated as an average: the average amount of diversity not found in a single, randomly chosen sample. Both α and β diversity are averages, using the same units of measure, The Shannon-Wiener Diversity Index, H, is calculated using the following equation: H = -( Pi(lnPi) where Pi is the proportion of each species in the sample. Mutations are the original source of variation in attributes among individuals and are the base cause of genetic diversity. - In biology and ecology, extinction is the termination of an organism or of a group of organisms normally a species. - The Effect of Fishing on Species and Genetic Diversity ... Loss of populations in the midst of a species range can result in fragmentation. Consider three communities, each made up of a total of 100 organisms, drawn from combinations of ten species, A to J.
