ResumoThis article reviews modern statistical approaches to estimating species diversity and biotic similarity from empirical samples of species abundance or incidence. Key methods include rarefaction, extrapolation, and non-parametric estimation of the asymptote of species richness. Hill numbers are presented as unifying indices of species diversity that take into account the relative abundance of different species. Species richness estimators, Hill numbers, and measures of biotic similarity can be extended to account for phylogenetic, taxonomic, and functional diversity of biological assemblages. These statistical methods control for sampling effects in biodiversity data and can be applied to many important questions in ecology.
