Population Structure

Phylogeography: F-statistics & Population Structure

Introduction to F-statistics: F_ST = 1 - [(1 - F_IT) / (1 - F_IS)]
    Draw-&-Replacement experiments with alleles
    Observed vs Expected Heterozygosity over multiple populations
    Structure of differences over different hierarchical levels
    F_ST as an estimator of N_em in an island model
    F_ST / (1 - F_ST) as a measure of genetic differentiation versus geographical distance in Sea Lions (Zalophus californianus)
    F_ST as a measure of genetic differentiation versus geographical distance in Humans

Two examples from marine & terrestrial populations of Newfoundland

        Ex.: Genetic tests of alternative hypothesis of breeding structure in Harp Seals, Pagophilus groenlandicus [Carr et al. 2015]

        Ex.: Genetic structure of an island subspecies of caribou , Rangifer tarandus terranovae [Wilkerson, Mahoney, & Carr 2018]
