  1. N = total number of samples per population. AR = rarefied allelic richness. Hs = rarefied gene diversity. Ne = effective population size, with 95% confidence intervals estimated by jack-knifing in square brackets. π = nucleotide diversity. Species-wide alignment values are reported as means of means across all loci ± standard deviation under rarefaction (n = 4). For Lake Alexandrina populations, gene diversities were also calculated for individual population alignments and rarefaction of n = 15 samples (reported second). Populations means across species were compared using either an unpaired two-samples t-test (T) or Wilcoxon rank test (W)
