They are implemented via the \code{vegan} package. +} +\details{ +These include the \sQuote{ace}, \sQuote{Chao1}, \sQuote{Hill}, and +\sQuote{Observed} richness measures. +See details for more information and references. + +The richness is calculated per sample. This is a standard index in community +ecology, and it provides an estimate of the number of unique species in the +community. This is often not directly observed for the whole community but +only for a limited sample from the community. This has led to alternative +richness indices that provide different ways to estimate the species +richness. + +Richness index differs from the concept of species diversity or evenness in +that it ignores species abundance, and focuses on the binary presence/absence +values that indicate simply whether the species was detected. + +The function takes all index names in full lowercase. The user can provide +the desired spelling through the argument \code{\link{name}} (see examples). + +The following richness indices are provided. + +\itemize{ + +\item{'ace' }{Abundance-based coverage estimator (ACE) is another +nonparametric richness +index that uses sample coverage, defined based on the sum of the +probabilities +of the observed species. This method divides the species into abundant +(more than 10 +reads or observations) and rare groups +in a sample and tends to underestimate the real number of species. The +ACE index +ignores the abundance information for the abundant species, +based on the assumption that the abundant species are observed regardless +of their +exact abundance. We use here the bias-corrected version +(O'Hara 2005, Chiu et al. 2014) implemented in +\code{\link[vegan:specpool]{estimateR}}. +For an exact formulation, see \code{\link[vegan:specpool]{estimateR}}. +Note that this index comes with an additional column with standard +error information.} + +\item{'chao1' }{This is a nonparametric estimator of species richness. It +assumes that rare species carry information about the (unknown) number +of unobserved species. We use here the bias-corrected version +(O'Hara 2005, Chiu et al. 2014) implemented in +\code{\link[vegan:specpool]{estimateR}}. This index implicitly +assumes that every taxa has equal probability of being observed. Note +that it gives a lower bound to species richness. The bias-corrected +for an exact formulation, see \code{\link[vegan:specpool]{estimateR}}. +This estimator uses only the singleton and doubleton counts, and +hence it gives more weight to the low abundance species. +Note that this index comes with an additional column with standard +error information.} + +\item{'hill' }{Effective species richness aka Hill index +(see e.g. Chao et al. 2016). +Currently only the case 1D is implemented. This corresponds to the exponent +of Shannon diversity. Intuitively, the effective richness indicates the +number of +species whose even distribution would lead to the same diversity than the +observed +community, where the species abundances are unevenly distributed.} + +\item{'observed' }{The \emph{observed richness} gives the number of species that +is detected above a given \code{detection} threshold in the observed sample +(default 0).

Diversity increases, in general, when species richness +#' or evenness increase. +#' +#' The following diversity indices are available: +#' +#' \itemize{ +#' +#' \item 'coverage': Number of species needed to cover a given fraction of +#' the ecosystem (50 percent by default). Tune this with the threshold +#' argument. +#' +#' \item 'faith': Faith's phylogenetic alpha diversity index measures how +#' long the taxonomic distance is between taxa that are present in the sample. +#' Larger values represent higher diversity. Using this index requires +#' rowTree. (Faith 1992) +#' +#' If the data includes features that are not in tree's tips but in +#' internal nodes, there are two options. First, you can keep those features, +#' and prune the tree to match features so that each tip can be found from +#' the features. Other option is to remove all features that are not tips. +#' (See \code{only.tips} parameter) +#' +#' \item 'fisher': Fisher's alpha; as implemented in +#' \code{\link[vegan:diversity]{vegan::fisher.alpha}}. (Fisher et al. 1943) +#' +#' \item 'gini_simpson': Gini-Simpson diversity i.e. \eqn{1 - lambda}, +#' where \eqn{lambda} is the +#' Simpson index, calculated as the sum of squared relative abundances. +#' This corresponds to the diversity index +#' 'simpson' in \code{\link[vegan:diversity]{vegan::diversity}}. +#' This is also called Gibbs–Martin, or Blau index in sociology, +#' psychology and management studies. The Gini-Simpson index (1-lambda) +#' should not be +#' confused with Simpson's dominance (lambda), Gini index, or +#' inverse Simpson index (1/lambda). +#' +#' \item 'inverse_simpson': Inverse Simpson diversity: +#' \eqn{1/lambda} where \eqn{lambda=sum(p^2)} and p refers to relative +#' abundances. +#' This corresponds to the diversity index +#' 'invsimpson' in vegan::diversity. Don't confuse this with the +#' closely related Gini-Simpson index +#' +#' \item 'log_modulo_skewness': The rarity index characterizes the +#' concentration of species at low abundance. Here, we use the skewness of +#' the frequency +#' distribution of arithmetic abundance classes (see Magurran & McGill 2011). +#' These are typically right-skewed; to avoid taking log of occasional +#' negative skews, we follow Locey & Lennon (2016) and use the log-modulo +#' transformation that adds a value of one to each measure of skewness to +#' allow logarithmization. +#' +#' \item 'shannon': Shannon diversity (entropy). +#' +#' } +#' +#' ## Dominance +#' +#' A dominance index quantifies the dominance of one or few species in a +#' community. Greater values indicate higher dominance. +#' +#' Dominance indices are in general negatively correlated with alpha diversity +#' indices (species richness, evenness, diversity, rarity). More dominant +#' communities are less diverse. +#' +#' The following community dominance indices are available: +#' +#' \itemize{ +#' +#' \item 'absolute': Absolute index equals to the absolute abundance of the +#' most dominant n species of the sample (specify the number with the argument +#' \code{ntaxa}). Index gives positive integer values. +#' +#' \item 'dbp': Berger-Parker index (See Berger & Parker 1970) calculation +#' is a special case of the 'relative' index. dbp is the relative abundance of +#' the most +#' abundant species of the sample. Index gives values in interval 0 to 1, +#' where bigger value represent greater dominance. +#' +#' \deqn{dbp = \frac{N_1}{N_{tot}}}{% +#' dbp = N_1/N_tot} where \eqn{N_1} is the absolute abundance of the most +#' dominant species and \eqn{N_{tot}} is the sum of absolute abundances of all +#' species. +#' +#' \item 'core_abundance': Core abundance index is related to core species. +#' Core species are species that are most abundant in all samples, i.e., in +#' whole data set. Core species are defined as those species that have +#' prevalence over 50\%. It means that in order to belong to core species, +#' species must be prevalent in 50\% of samples. Core species are used to +#' calculate the core abundance index. Core abundance index is sum of relative +#' abundances of core species in the sample. Index gives values in interval +#' 0 to 1, where bigger value represent greater dominance. +#' +#' \deqn{core_abundance = \frac{N_{core}}{N_{tot}}}{% +#' core_abundance = N_core/N_tot} where \eqn{N_{core}} is the sum of absolute +#' abundance of the core species and \eqn{N_{tot}} is the sum of absolute +#' abundances of all species. +#' +#' \item 'gini': Gini index is probably best-known from socio-economic +#' contexts (Gini 1921). In economics, it is used to measure, for example, how +#' unevenly income is distributed among population. Here, Gini index is used +#' similarly, but income is replaced with abundance. +#' +#' If there is small group of species +#' that represent large portion of total abundance of microbes, the inequality +#' is large and Gini index closer to 1. If all species has equally large +#' abundances, the equality is perfect and Gini index equals 0. This index +#' should not be confused with Gini-Simpson index, which quantifies diversity. +#' +#' \item 'dmn': McNaughton’s index is the sum of relative abundances of the two +#' most abundant species of the sample (McNaughton & Wolf, 1970).
