spec_sample: Sample species richness
In mobsim: Spatial Simulation and Scale-Dependent Analysis of Biodiversity Changes
spec_sample R Documentation
Sample species richness
Description
Expected species richness in a random sample of fixed size.
Usage
spec_sample(abund_vec, n)
Arguments
abund_vec
Species abundance distribution of the community (integer vector)
n
Sample size in terms of number of individuals (integer)
Details
The expected number of species is calculated after Hurlbert 1971, Equation 3.
spec_sample is similar to the function rarefy
in the R package vegan.
Value
Expected number of species in a sample of n individuals
References
Hurlbert, S.H. 1971. The nonconcept of species diversity: a critique and +
alternative parameters. Ecology 52, 577-586.
Examples
sad1 <- sim_sad(100, 1000)
spec_sample(abund_vec = sad1, n = 20)
