Research

Overview

Research centres on understanding the process of speciation in heliconiine and ithomiine butterflies. Both groups of butterflies are found in the neotropics and are noted for the diversity of wing colour patterns found within species, as well as also for mimetic convergence of colour patterns between species (Müllarian mimicry).

Making use of the Heliconius melpomene reference genome, the current focus involves using high-throughput sequencing approaches to understand the speciation process at the scale of the genome. In particular we are investigating genome-wide patterns of divergence, adaptive introgression, and quantifying the amount of genomic exchange between species.

Discoveries

We have recently published the genome sequence of the neotropical butterfly Heliconius melpomene. By comparing the genomes of closely-related Heliconius species we have discovered that adaptive genes involved in determining mimicry colour patterns have been shared between species by hybridization.
