WebbShannon Wiener Diversity Index; Simpson’s index; All of the parameters can easily be determined by using this free Shannon diversity index calculator immediately and accurately. What are 4 levels of biodiversity? The four major levels of the biodiversity include the following: Webbdiversity indices, take into account the number of species (the richness) and their relative contribution (the evenness); e.g.: Simpson index; Shannon-Wiener index; phylogenetic diversity measures, include information on phylogenetic relationships among species phylogenetic diversity (PD) index; Faith (1992) topology based measures
