Example of rarefaction
In ecology, rarefaction is a technique to assess species richness from the results of sampling. Rarefaction allows the calculation of species richness for a given number of individual samples, based on the construction of so-called rarefaction curves. This curve is a plot of the number of species as a function of the number of samples. Rarefaction curves generally grow rapidly at first, as the most co… WebExample 1: Comparing forest diversity along elevation standardized to sample area, number of individuals and sample completeness.

Did you know?
WebThe rarefaction curve is a plot of the number of species against the number of samples. This curve is created by randomly re-sampling the pool of N samples several times and then plotting the average number of species found on each sample. Generally, it initially grows rapidly (as the most common species are found) and then slightly flattens ... WebThe sample can be a vector giving the sample sizes for each row. If the sample size is equal to or larger than the observed number of individuals, the non-rarefied community will be returned. The random rarefaction is made without replacement so that the variance of rarefied communities is rather related to rarefaction proportion than to the ...

WebThe spatially constrained rarefaction curve (Chiarucci et al. 2009) also known as the sample-based accumulation curve (Gotelli and Colwell 2001) can be computed in one of two ways which is determined by the argument spat_algo. In the kNN approach each plot is accumulated by the order of their spatial proximity to the original focal cell.
