Testing defensive compounds from 30 nudibranch species, we found no relationship between palatability and toxicity, but instead classified compound types into categories: Class I & II—highly unpalatable and highly toxic; Class I—weakly unpalatable and highly toxic; Class II—highly unpalatable but weakly toxic; WR (weak or no response). These different classes help us better understand the foraging decisions faced by predators, the resultant selection pressures imposed on prey and the evolution of different anti-predator strategies.

We tested the efficacy of color (genotypes: WW/Wy = white, yy = yellow), smell (synthesised methoxypyrazines) and taste (sequestered pyrrolizidine alkaloids) during the predation of wood tiger moths by blue tits. Multimodal signals improve survival. Both genetic background and predation stage matter.

This study investigates the evolution of warning signals and chemical defences in a putative mimicry ring and explores the interface between undefended Batesian mimics and equally defended Müllerian mimics by disentangling toxicity and taste.

Predators may exert stabilizing selection on only part of their prey's colour pattern: colour components that were learned by fish (yellow rim) did not vary between populations despite high genetic divergence, but the other components (red spots) were highly variable.
