Welcome Wyatt Toure!

Wyatt Toure

Wyatt is at STRI as a visiting researcher for three months investigating the behavioural consequences of evolved differences in the neuroanatomy of Heliconius and non-Heliconius butterflies as a result of being awarded funding through McGill’s NSERC-CREATE in Biodiversity, Ecosystem Services and Sustainability program. He is a graduate student at McGill University’s Department of Biology in Montreal, Canada working with Professor Simon Reader where he researches the factors that constrain behavioural plasticity in Trinidadian guppies. His research interests lie broadly within evolutionary biology, animal behaviour, neurobiology and genomics. In addition to research he is interested in the storytelling of science which he pursues by producing scientific videos.

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.

Welcome Lina Melo!

Lina Melo

Lina recently finished her bachelor’s degree at the University of Los Andes in Colombia. She is actually doing a three-month internship assisting Laura Hebberecht and Fletcher Young’s projects, and is collecting life history data to unravel the secrets of the expanded mushroom bodies of Heliconius butterflies. In addition to insects, Lina admires spiders a lot, and she is interested in pursuing a master’s program focused on sexual behavior. Lina has worked before in Gamboa attending Laura Southcott’s doctoral project and is happy to be back.
