PAICE is the acronym for Phylogeographic Analysis of Island Colonization Events, a haplotype-based method to estimate the number of inter-island colonization events experienced by a species in an island-like system. This method was originally designed for oceanic archipelagos, but it works for every island-like system in which biogeographic barriers exist among populations.
This method creates rarefaction curves to estimate the number of colonization events accounting for sample size considering both individual/population sampling and genetic sampling. For additional information, see our publication (Coello et al. 2022).
