We have a new paper on mimicry and behaviour in poison frogs out now in @jevbio.bsky.social 🧪🌎 The non-toxic mimic Allobates zaparo mimics the bold behaviour of the poisonous Ameerega bilinguis, but is more likely to jump before physical contact from a predator academic.oup.com/jeb/advance-...

Our new paper on aposematism, camouflage, & mimicry in poison frogs is out! These frogs use colour for both salient signalling & crypsis but detectability & mimicry depend on viewing angle and frog behaviour. 🧪🌎 Poisonous Am. bilinguis (right) & mimetic Al. zaparo (left). doi.org/10.1093/behe...

Detectability of a poison frog and its Batesian mimic depends on body posture and viewing angle

Abstract. Aposematic signals warn predators that prey should be avoided due to dangerous secondary defences. However, as warning signals do not always prod

Our new paper on transparency and warning signals in clearwing butterflies is out now in Ecology & Evolution 🎉 We found that when predators are familiar with toxic butterflies the addition of bright colours to transparent wings does not reduce butterfly survival 🧪🌎 doi.org/10.1002/ece3...

Imperfections in transparency and mimicry do not increase predation risk for clearwing butterflies with educated predators

Clearwing butterflies seemingly balance camouflage (conferred by transparent wing elements) with alternate anti-predatory strategies including warning coloration, paradoxically resulting in a diversi...
