Yosemite Toad (Anaxyrus canorus) transcriptome reveals interplay between speciation genes and adaptive introgression

Genomes are heterogeneous during the early stages of speciation, with small “islands” of DNA appearing to reflect strong adaptive differences, surrounded by vast seas of relative homogeneity. As species diverge, secondary contact zones between them can act as an interface, and selectively filter through advantageous alleles of hybrid origin. Such introgression is another important adaptive process, one that allows beneficial mosaics of recombinant DNA (“rivers”) to flow from one species into another. Although genomic islands of divergence appear to be associated with reproductive isolation, and genomic rivers form by adaptive introgression, it is unknown whether islands and rivers tend to be the same or different loci. We examined three replicate secondary contact zones for the Yosemite toad (Anaxyrus canorus) using two genomic datasets and a morphometric dataset to answer the questions: (1) How predictably different are islands and rivers, both in terms of genomic location and gene fun..., , , # Yosemite Toad (*Anaxyrus canorus*) transcriptome reveals interplay between speciation genes and adaptive introgression --- ## GENERAL INFORMATION Title of Dataset: YOTOAD_ADAPTIVE_INTROGRESSION Author Information: Paul Maier [[e-mail]](mailto:[e-mail]) San Diego State University 5500 Campanile Drive San Diego, CA 92182 Principal Investigator: Paul Maier Co-investigators: Amy Vandergast, Andrew Bohonak Date of data collection: 2011–2013 Geographic location of data collection: Yosemite National Park --- ## SHARING/ACCESS INFORMATION No licenses/restrictions have been placed on the data. \** NOTE: ALL GEOGRAPHIC COORDINATES HAVE BEEN REMOVED TO PROTECT THE LOCATION OF THIS FEDERALLY PROTECTED SPECIES ** \** PLEASE CONTACT THE CORRESPONDING AUTHOR TO REQUEST PERMISSION FOR THE ORIGINAL COORDINATES ** Recommended citation for the data: Maier P.A., Vandergast A.G., Bohonak A.J.
