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

Abbreviations: n, sample size; h, number of haplotypes, S, number of polymorphic sites; Hd, gene diversity; π, nucleotide diversity as mean number of pairwise differences in the population; Tajima’s D; Fu’s Fs. 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; M, relative rate of gene exchange between demes; -, not estimated; bold font represents significance tests where P
