Data from: Mito-nuclear discordance at a mimicry color transition zone in bumble bee Bombus melanopygus

Data supporting the conclusions from “Mito-nuclear discordance at a mimicry color transition zone in bumble bee Bombus melanopygus." This study amassed specimen phenotype data to infer patterns of color distribution over the last one hundred years in this mimicry zone, examined population genetics among the mimicry forms across the tranisstion zone of B. melanopygus by comparing sequences from mitochondrial COI barcode sequences, color-controlling loci, and the rest of the genome. These data suggest the two lineages were historically isolated, acquired fixed color differences, and then came into secondary contact with ongoing gene flow. However, the transition zone exhibits asymmetries: COI haplotypes transition further south than the color pattern and nuclear transition zone, and both patterns transition over shorter distances in the south.

    Description
    • Background
    • As hybrid zones exhibit selective patterns of gene flow between otherwise distinct lineages, they can be especially valuable for informing processes of microevolution and speciation. The bumble bee, Bombus melanopygus, displays two distinct color forms, a northern “Rocky Mountain” color form with ferruginous mid-abdominal segments (B. m. melanopygus) and a southern “Pacific” form with black mid-abdominal segments (B. m. edwardsii), thought to be generated by Müllerian mimicry. These morphs meet in an unusually narrow transition zone in northern California and southern Oregon. To understand the historical formation of this transition zone, we amassed specimen phenotype data to infer patterns of color distribution over the last one hundred years in this mimicry zone. We then examined population genetics among the mimicry forms across the transition zone of B. melanopygus by comparing sequences from mitochondrial COI barcode sequences, color-controlling loci, and the rest of the genome.
    • Results
    • Mitochondrial data support two geographically distinct mitochondrial haplogroups that meet within the color transition zone. This clustering is also supported by the nuclear genome, which, while showing strong admixture, clusters individuals first by mitochondrial haplotype and second by position along the geographic cline. These data suggest the two lineages were historically isolated, acquired fixed color differences, and then came into secondary contact with ongoing gene flow. However, the transition zone exhibits asymmetries: COI haplotypes transition further south than the color pattern and nuclear transition zone, and both patterns transition over shorter distances in the south.
    • Conclusions
    • This study highlights the dynamics of gene flow that occur in contact zones, presenting another example of mito-nuclear discordance in population histories in these zones. In this case, discordant gene flow may be driven by a combination of selection driven by mimicry and asymmetric pre-mating bias, a partial barrier which would place this species along the speciation continuum.
