Signatures of population bottlenecks on microsatellite variation.

Intrapopulation genetic diversity indices (, FIS, and HHW) and results of two tests for population bottlenecks (Bottleneck and M-ratio), based on averages across microsatellite loci.Abbreviations: – observed mean number of alleles per locus; FIS – observed mean inbreeding coefficient; HHW – expected heterozygosity at Hardy-Weinberg equilibrium; HMD – expected heterozygosity at mutation-drift equilibrium, assuming a two-phase model (TPM) of mutation; –estimate of the population mutational parameter; m – observed mean ratio of allelic size range against total number of alleles; P-value –, from an equilibrium distribution; m0.05 – critical M values for equivalent samples obtained from populations at mutation-drift equilibrium under different scenarios of mutational input per generation ( value estimated from the data, , ).M-ratio results that turned out to be significant under all three scenarios are shown in bold.
