Here, we briefly explain the basic approach, while the detailed steps, parameter settings and statistics are reported in the Additional file 6 scripts for data processing can be found on Dryad Digital Repository: Huateng Huang and Daniel L. We studied eight matching species pairs that are characterized by contrasting patterns of dichromatism, comprising seven avian families Additional file 1 : Table S1.
Nucleotide variation, linkage disequilibrium and founder-facilitated speciation in wild populations of the zebra finch Taeniopygia guttata Genetics. The 22 pairs of autosomes are referred to by number basically in inverse correlation with their size. Species divergence in sexually selected traits: increase in song elaboration is related to decrease in plumage ornamentation in finches.
Additional files Additional file 1: Table S1. Wallace AR. Discussion In this study, we investigated the association between plumage dichromatism and genomic variation in birds. Substitution-rate ratios for matched pairs of sexually dichromatic red and monochromatic black bird species. Besides each plot, p values from testing the difference between dichromatic and monochromatic samples are reported.
Comparative genomics based on massive parallel transcriptome sequencing reveals patterns of substitution and selection across 10 bird species. Molecular ecology resources. Yet, no consistent differences were noted between dichromatic and monochromatic species p values from linear regression controlling for the effect of sequencing runs and phylogenetic distance to the reference genome were 0.
