Hill numbers diversity

WebJun 18, 2024 · Hill numbers link different lines of beta diversity research together and unify multiple dissimilarity measures into a common expression (Chao et al., 2024; Chao & Chiu, 2016; Jost, 2007). Temporal partitioning of Hill-number-based beta diversity could thus give us a synthetic understanding of community dynamics. WebGeneralisation of Hill numbers for beta functional diversity. Framework of Chao et al. (2024) also allows computing beta-diversity, with 2 framework similar to Jaccard and Sorensen ones for taxonomic diversity. The mFD:beta.fd.hill () function computes these indices. NB Note that total weight of assemblages is affecting computation of ...

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. In demography, the entities of interest can be people, and the types of interest various demographic groups. In information science, the enti…
