A complex genomic architecture underlies reproductive isolation in a North American Oriole hybrid zone
<p>Natural hybrid zones provide powerful opportunities for identifying the mechanisms that facilitate and inhibit speciation. Documenting the extent of genomic admixture allows us to discern the architecture of reproductive isolation through the identification of isolating barriers. This approach is particularly powerful for characterizing the accumulation of isolating barriers in systems exhibiting varying levels of genomic divergence. Here, we use a hybrid zone between two species--the Baltimore (<em>Icterus galbula</em>) and Bullock's (<em>I. bullockii</em>) orioles--to investigate this architecture of reproductive isolation. We combine whole genome re-sequencing with data from an additional 313 individuals amplityped at ancestry-informative markers to characterize fine-scale patterns of admixture, and to quantify links between genes and the plumage traits. On a genome-wide scale, we document several putative barriers to reproduction, including elevated peaks of divergence above a generally high genomic baseline, a large putative inversion on the Z chromosome, and complex interactions between melanogenesis-pathway candidate genes. Concordant and coincident clines for these different genomic regions further suggest the coupling of pre- and post-mating barriers. Our findings of complex and coupled interactions between pre- and post-mating barriers suggest a relatively rapid accumulation of barriers between these species, and they demonstrate the complexities of the speciation process.</p>
Data from Quantitative Analyses of Coupling in Hybrid Zones
<p>This data set comprises simulated and empirical genetic data and associated metadata that were analyzed for the publication "Quantitative Analyses of Coupling in Hybrid Zones" (doi:10.1101/cshperspect.a041434).</p> <p>The data set includes two compressed directories (tar.gz files).</p> <p>dfuseSims.tar.gz contains the simulated data. These are the main (.main) output files from the program dfuse. The simulation conditions are encoded in the file names, this includes the number of demes (number after d), the number of loci (number after L), theta (number after theta) and the replicate number (number after rep). The genetic map size (M) is given if not 1 and the migration rate (m) is given if not 0.1. The directory includes 2250 simulated data sets.</p> <p>data.tar.gz contains the empirical data sets re-analyzed for this paper. We specifically include the final input files needed for analysis. The file formats vary slightly but are described in detail in the supplemental material for the publication and in the R scripts used for analysis. The latter are available from GitHub (https://github.com/zgompert/ClineCoupling). There is one directory per data set within the main compressed directory.</p> <p> </p>
