Invasive insect hybridizes with local pests
Journal Article
Supergene evolution triggered by the introgression of a chromosomal inversion
Journal Article
Supergenes are groups of tightly linked loci whose
variation is inherited as a single Mendelian locus
and are a common genetic architecture for complex
traits under balancing selection [1–8]. Supergene alleles
are long-range haplotypes with numerous mutations...

Simultaneous TE analysis of 19 heliconiine butterflies yields novel insights into rapid TE-based genome diversification and multiple SINE births and deaths
Journal Article
Transposable elements (TEs) play major roles in the evolution of genome structure and function. However, because of their repetitive nature, they are difficult to annotate and discovering the specific roles they may play in a lineage can be a daunting...
Renewed diversification following Miocene landscape turnover in a Neotropical butterfly radiation
Journal Article
Aim
The landscape of the Neotropical region has undergone dynamic evolution throughout the Miocene, with the extensive Pebas wetland occupying western Amazonia between 23 and c. 10 Ma and the continuous uplift of the Andes mountains. The complex...
Geographic contrasts between pre‐ and postzygotic barriers are consistent with reinforcement in Heliconius butterflies
Journal Article
Identifying the traits causing reproductive isolation and the order in which they evolve is fundamental to understanding speciation. Here, we quantify prezygotic and intrinsic postzygotic isolation among allopatric, parapatric, and sympatric populations...
Reply to Andrew Brower’s critique of the evidence for hybridization among Heliconius butterfly species in the wild
Journal Article
Andrew Brower recently published a long article in this journal that seeks to dismantle evidence for hybridization between species of Heliconius butterflies. The main evidence that Brower criticizes here is given in two papers published by my colleagues...
Genomic architecture and introgression shape a butterfly radiation
Journal Article
Following gene flow in butterfly genomes
The role of hybridization in evolution and species radiations has long been debated. In Heliconius butterflies, introgression was a major factor in their radiation, and the genetic variation it imparted into...
Comparing adaptive radiations across space, time, and taxa
Journal Article
Adaptive radiation plays a fundamental role in our understanding of the evolutionary process. However, the concept has provoked strong and differing opinions concerning its definition and nature among researchers studying a wide diversity of systems. Here...
