- Each biodiversity index weighs richness (number of categories, types, species, or classes) and distribution (number of observations per category, type, species, or class) differently. By assigning different weights to richness and distribution, these indices capture the importance of both factors in determining overall biodiversity.

5 days ago · A diversity index is a quantitative measure that reflects how many different types (such as species) there are in a dataset (a community). These indices are statistical representations of biodiversity in different aspects (richness, evenness, and dominance).
Different authors have used different indices to measure species diversity and the whole subject area has become confused with poor terminology and an array of possible measures. Chiarucci (2012) and Magurran and McGill (2011) have reviewed the problem.

Feb 9, 2021 · In this paper we explain coverage and Hill diversity, provide guidelines for how to use them together to measure species diversity, and demonstrate their use with examples from our own data.
Aug 28, 2014 · Intuitively, species or trait abundance is also important for diversity, and the proportional abundance of species can be incorporated into indices representing diversity.
Including these trait-based measures of diversity allowed us to test whether or not they behaved similarly to the better studied species diversity. We used path analysis to determine whether compound indices detected more relationships between diversities of different organisms and traits than more basic indices.
