WebShannon Biodiversity Index can never be Conclusive [ edit] High value of Shannon Index does not indicate high diversity only but both the high diversity or high uniformity (both of the extreme cases). So this measur does not indicate the biodiversity correctly from mathematical point of view. WebDefinitions of alpha diversity can also differ in what they assume species diversity to be. Often researchers use the values given by one or more diversity indices, such as species richness (which is simply a count of species), the Shannon index or the Simpson index (which take into account also species proportional abundances).
