The goal in many  biodiversity analyses is to make a fair comparison and assessment of diversity measures (e.g. species richness, species diversity, phylogeaetic diversity and functional diversity) among multiple assemblages. For most measures, it is well known that the empirieal diversity sample are dependent on sample size or sampling efforts. When samples are incomplete, standardization via rarefacction and extrapolation is needed; rarefaction and extrapolation method allow for fair and meaningful comparison of diversity estimates for standardised samples on the basis of sample size or sample completeness.
