Hidden species diversity in sylvirana nigrovittata (amphibia: ranidae). The importance of analyzing the determinants of biodiversity and community composition by using multiple trophic levels is well recognized; however, relevant data are lacking. Diversity indices provide more information about community composition than simply species richness (i.e., the number of species present); they also take the relative abundances of different species into account. Deciphering diversity indices for a better understanding of microbial. Facilities related to diversity are discussed in a vegan vignette that can be read with browseVignettes("vegan").

When diversity indices are used in ecology, the types of interest are usually species, but they can also be other categories, such as genera, families, functional types or haplotypes. The entities of interest are usually individual plants or animals, and the measure of abundance can be, for example, number of individuals, biomass or coverage. 2006, The Ecology of Plants Diversity and Productivity Great Smoky Mtns.

Simpson's Index ( D ) measures the probability that two individuals randomly selected from a sample will belong to the same species (or some category other than species). Species richness. DIVERSITY INDICES: SIMPSON'S D AND E. Introduction: A diversity index is a mathematical measure of species diversity in a community. Relative to other diversity indices, such as Simpson’s index, it is considered sensitive to the addition of rare species (Krebs, 1989). ... Habitat Suitability Indices (HSI). Highly specialized microbial diversity in … Simpson's Diversity Indices The term 'Simpson's Diversity Index' can actually refer to any one of 3 closely related indices.
