In this episode, Matthew speaks with Swanne Gordon (@Swanne Gordon), Assistant Professor of Biology at Washington University in St. Louis.
They talk about diversity in both nature and in the biological sciences. The research focus of the conversation focuses on Swanne's experimental and modeling work to understand polymorphism among aposematic wood tiger moths, and the surprising outcomes that positive density dependent selection can have, when combined with migration between populations.
Then after the break they discuss the lack of racial and ethnic diversity in biological sciences, especially in evolutionary biology. Swanne describes her own experiences and identifies areas of progress and failure in our field. Then they close their conversation by discussing the benefits of increasing diversity in the model systems that we study.
This week's Two-Minute Takeaway comes from Dishari Dasgupta (@DishariDg), a PhD student at IISER Kolkata. Read Dishari's work on food preference of urban langurs here.
