Data from: Genome divergence and the genetic architecture of barriers to gene flow between Lycaeides idas and L. melissa

Zachariah Gompert, Lauren K. Lucas, Chris Clark Nice & C. Alex Buerkle
Genome divergence during speciation is a dynamic process that is affected by various factors, including the genetic architecture of barriers to gene flow. Herein we quantitatively describe aspects of the genetic architecture of two sets of traits, male genitalic morphology and oviposition preference, that putatively function as barriers to gene flow between the butterfly species Lycaeides idas and L. melissa. Our analyses are based on unmapped DNA sequence data and a recently developed Bayesian regression...

Data from: Genomic collinearity and the genetic architecture of floral differences between the homoploid hybrid species I. nelsonii and one of its progenitors, I. hexagona

Hybrid speciation represents a relatively rapid form of diversification. Early models of homoploid hybrid speciation suggested that reproductive isolation between the hybrid species and progenitors primarily resulted from karyotypic differences between the species. However, genic incompatibilities and ecological divergence may also be responsible for isolation. Iris nelsonii is an example of a homoploid hybrid species that is likely isolated from its progenitors primarily by strong prezygotic isolation, including habitat divergence, floral isolation, and post-pollination prezygotic...

Data from: Specificity, rank preference and the colonization of a non-native host plant by the Melissa blue butterfly

Animals often express behavioral preferences for different types of food or other resources, and these preferences can evolve or shift following association with novel food types. Shifts in preference can involve at least two phenomena: a change in rank preference or a change in specificity. The former corresponds to a change in the order in which hosts are preferred, while a shift in specificity can be an increase in the tendency to utilize multiple hosts....

Data from: An evaluation of the hybrid speciation hypothesis for Xiphophorus clemenciae based on whole genome sequences

Molly Schumer, Rongfeng Cui, Bastien Boussau, Ronald Brice Walter, Gil G. Rosenthal & Peter Andolfatto
Once thought rare in animal taxa, hybridization has been increasingly recognized as an important and common force in animal evolution. In the past decade, a number of studies have suggested that hybridization has driven speciation in some animal groups. We investigate the signature of hybridization in the genome of a putative hybrid species, Xiphophorus clemenciae, through whole genome sequencing of this species and its hypothesized progenitors. Based on analysis of this data, we find that...
