Had an amazing time at @behaviour2025.bsky.social in Kolkata! Got to see soo much diverse and cool research in the fields behavioural and integrative ecology and meet so many brilliant researchers.
Thanks to all the organisers!
Lastly, thanks to @biologists.bsky.social for funding my travel!

How many convergent switches in Müllerian mimicry can be explained by parallel evolution at ivory and optix genes? Amazing work by Ben Chehida, Dasmahapatra, Meier et al.! doi.org/10.1101/2025...

So very excited for the magnum opus of my #PhD to finally be out in @pnas.org. 🎉🎉 We demosntrate that mutualistic co-mimicking tropical butterflies not only converge in light microhabitat but, as a consequence, have also converged in visual system morphology! 1/n😀

Very excited about this paper led by Erika Castro. She has shown that Heliconius were ancestrally plastic in how they acquired their cyanogens, but some species have lost the ability to biosynthesise toxins, and have lost genes involved www.biorxiv.org/content/10.1...
Gene loss associated with plasticity-first evolution in Heliconius butterflies
Phenotypic plasticity occurs when a genotype can produce more than one phenotype under different environmental conditions. Genetic accommodation allows plastic phenotypes to be tuned to new environmen...
