Correction: Distance-Based Functional Diversity Measures and Their Decomposition: A Framework Based on Hill Numbers
نویسندگان
چکیده
In this Appendix, we summarize some basic properties of the three classes of functional diversity measures: (1) functional Hill number ) (Q D q which quantifies the effective number of equally abundant and equally distinct species in an assemblage with a constant species pairwise distance Q, where Q denotes Rao’s quadratic entropy; (2) mean functional diversity MD(Q) = Q Q D q × )] ( [ which quantifies the effective sum of functional distances between a fixed species to all other species; and (3) (total) functional diversity FD(Q) ( ) ( ) ( Q MD Q D q q × = ), which quantifies the effective total distance between species of an assemblage. Since the three measures are closely related, all the properties are shared.

Distance-Based Functional Diversity Measures and Their Decomposition: A Framework Based on Hill Numbers
Hill numbers (or the "effective number of species") are increasingly used to characterize species diversity of an assemblage. This work extends Hill numbers to incorporate species pairwise functional distances calculated from species traits. We derive a parametric class of functional Hill numbers, which quantify "the effective number of equally abundant and (functionally) equally distinct speci...
متن کاملSupporting Information Distance-based functional diversity measures and their decomposition: a framework based on Hill numbers
As indicated in the main text, we can apply the additive decomposition to the three measures, ) (Q D (Eq. 3), qMD(Q) (Eq. 4a) and qFD(Q) (Eq. 4b); here the equations numbers refer to those in the main text. For example, we define the “functional diversity excess” as ) ( ) ( Q FD Q FD q q . This is also an interpretable measure. However, this excess measure cannot be directly applied to co...
متن کاملRarefaction and extrapolation with Hill numbers: a framework for sampling and estimation in species diversity studies
Quantifying and assessing changes in biological diversity are central aspects of many ecological studies, yet accurate methods of estimating biological diversity from sampling data have been elusive. Hill numbers, or the effective number of species, are increasingly used to characterize the taxonomic, phylogenetic, or functional diversity of an assemblage. However, empirical estimates of Hill n...
متن کاملPhylogenetic diversity measures based on Hill numbers.
We propose a parametric class of phylogenetic diversity (PD) measures that are sensitive to both species abundance and species taxonomic or phylogenetic distances. This work extends the conventional parametric species-neutral approach (based on 'effective number of species' or Hill numbers) to take into account species relatedness, and also generalizes the traditional phylogenetic approach (bas...
متن کاملEvaluation of an Integrated Framework for Biodiversity with a New Metric for Functional Dispersion
Growing interest in understanding ecological patterns from phylogenetic and functional perspectives has driven the development of metrics that capture variation in evolutionary histories or ecological functions of species. Recently, an integrated framework based on Hill numbers was developed that measures three dimensions of biodiversity based on abundance, phylogeny and function of species. Th...
