Molecular diversity indices and population demographic parameters under two models of population expansion for <i>Phreatomerus latipes</i> from spring complexes throughout the Lake Eyre region.

<p>Abbreviations: <i>n</i>, sample size; <i>h</i>, number of haplotypes, <i>S</i>, number of polymorphic sites; H_d, gene diversity; π, nucleotide diversity as mean number of pairwise differences in the population; Tajima’s <i>D</i>; Fu’s <i>F_s</i>. Model of demographic expansion parameters, where τ is an index of time since the expansion expressed in units of mutational time; θ₀ and θ₁ are pre- and post-expansion values for the mutation parameter (that is, 2 Nμ, where N is the effective female population size and μ is the mutation rate per gene per generation); SSD, Sum of Squared Deviations between the observed and the expected mismatch as a test statistic; Model of spatial expansion parameters where: θ, the effective size of each deme; <i>M</i>, relative rate of gene exchange between demes; -, not estimated; bold font represents significance tests where <i>P</i><0.05; inf, infinite estimate.
