Happy to share our new @PNASnews paper, a multi-national team effort led by @JPLawrencePhoto aiming to understand how variation in warning signals can persist, and providing new perspectives on frogs' chemical defences (⚠️: toxicity≠unpalatability!) (1/n) pnas.org/content/early/…
@PNASNews @JPLawrencePhoto In two populations of dyeing poison frogs displaying the same pattern but different colour, we deployed an army of clay models to test the reaction of wild predators to known and novel colour patterns. (2/n) #colsci 
@PNASNews @JPLawrencePhoto We expected that local colour patterns were less attacked by wild predators, but that was not the case in either population. We moved on to test if maybe one of these colours (white, yellow) was inherently easier to learn to avoid. So we tested that in the lab using chicks (3/n)
