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...

Blown away by this paper on body size variation among 11,264 (!!!) measured plethodontid salamanders over an elevational gradient. Super surprised to see that it is not temperature that has the main explanatory role, but mostly humidity and precipitation 🧪🦎
