DESCRIPTION:I am a new research fellow in the Zoology department\, working
  with Chris Jiggins on _Heliconius_ butterfly genomes. In this talk\, I wi
 ll present my plans for the next three years\, drawing on recent research 
 from the _Heliconius_ community.\n\nThe _Heliconius_ butterflies are a wel
 l-known example of a diverse adaptive radiation\, with over fifty species\
 , each with tens of subspecies\, displaying considerable variation in comp
 lex wing patterning. In recent years\, it has been shown that the wing pat
 terns of seven sympatric subspecies of _Heliconius numata_ are maintained 
 by chromosomal inversions across the single major colour patterning locus 
 in this species\, preventing recombination and preserving many multigene h
 aplotypes. I plan to investigate whether similar inversions can be found i
 n other _Heliconius_ species and whether the colour patterning loci are su
 fficient for sympatric speciation or whether additional loci may be involv
 ed. To do this\, I will employ high throughput sequencing technologies\, a
 s we have recently done to demonstrate introgression in the _Heliconius me
 lpomene_ clade. I will discuss the importance of high throughput sequencin
 g in making the case for introgression in _Heliconius_ and show how we pla
 n to use sequencing technology to investigate the role of recombination an
 d rearrangement during speciation.
