Join us for Krzysztof Kozak’s Tupper Presentation, March 19th 12:30pm!

Kozak's Erato Map Plots

Krzysztof “Chris” Kozak will be presenting a talk titled, Evolution and Ecology of Neotropical Butterflies Through a Genomic Lens Tuesday, March 19th at the Tupper Conference Center at 12:30pm.

Krzysztof KozakNeotropics harbor the greatest diversity of life on Earth, but the relatively poor fossil record makes it difficult to peek into the past, especially of invertebrates. Genome sequencing has provided the solution, as accumulated variation in natural populations is a repository of information about recent and ancient events. I will demonstrate how genomics has opened a window onto the evolution of diversity within and between species of Heliconius butterflies, the classic subject of studies on Mullerian mimicry and other adaptations to the complex tropical environments. Population genomics of the 29 races of H. erato and H. melpomene reveal that the intricate mosaic of mimetic wing patterns has evolved independently in each species, with varied importance of interspecific introgression. Continental scale sampling coupled with niche models reveals differential roles for the changing landscape and climate, leading to local adaptation and divergent population structures of mimetic lineages. The classic example of co-evolution is therefore not strictly co-evolved.

Location of 2018 Heliconius meeting announced!

Matheu Joron is hosting this years Heliconius meeting in Montpellier, France from August 23rd – 25th.  The meeting will follow on the joint European and North American Evolution Society meeting.

The meeting will be held at the Maison des Sciences de l’Homie, in central Montpellier, near the botanical garden and the Old Faculty of Medicine. The venue is within the historical center and will therefore be easy to reach for everyone, on foot or by public transport.

ATAC Workshop Poster

The workshop organized by Carolina Concha and supported by STRI and UPR brought students, postdocs, and professors down to the Gamboa lab to learn how to do ATAC-seq, a genomic method for characterizing the regulatory landscape.
