Nucleotide variation for N. incisum, N. franchetii, N. oviforme, and N. forrestii, where the number of samples (N), length (L), number of segregating sites (S), and the minimum number of recombination events (R_m) are averaged over all nuclear loci. Watterson’s θ (θ_w) and the average number of pairwise nucleotide differences (π) are per site estimates of the population scaled mutation parameter θ averaged over all nuclear loci
