Table 1 The diversity metrics calculated in this study

From: Simulated biodiversity hotspots from traditional ecological knowledge and Western metrics do not always overlap

Diversity metric

Definition

Citation

Metrics of taxonomic diversity

 Species richness

The number of species within a simulated community.

89

Metrics of functional diversity

 Functional richness

The amount of functional space occupied by the species of a simulated community. The complete set of functional traits defines the functional space.

90

 Functional dispersion

The mean distance in multidimensional trait space of individual species to the centroid of all species in a simulated community.

91

 Functional Rao’s entropy

A measure of diversity based on the proportional abundances of species and the dissimilarity among them.

92

Metrics of TEK-based diversity

 Recorded number of Indigenous botanical uses (Ethnobotany)

The summed number of traditional uses of species and their parts in a simulated community. Traditional uses include foods, drugs, dyes, fibers, and religious uses, as recorded by Indigenous peoples.

93

 Recorded number of Indigenous names (Ethnotaxonomy)

The number of Indigenous names associated with the species and their parts in a simulated community.

33

Metrics of phylogenetic diversity

 Faith’s phylogenetic diversity

The sum of the branch lengths of a phylogenetic tree connecting all species in the simulated community.

94

 Phylogenetic species variability (PSV)

Quantifies how phylogenetic relatedness decreases the variance of a hypothetical trait shared by all species in a simulated community.

83

 Phylogenetic Rao’s entropy (Q)

A measure of diversity based on the proportional abundances of species phylogenetic branches and the dissimilarity among them.

92

 Phylogenetic species richness (PSR)

The number of species in a simulated community multiplied by the community’s PSV (see above).
