Automimicry destabilizes aposematism: predator sample-and-reject behaviour may provide a solution
G Gamberale-Stille, T Guilford - Proceedings of the …, 2004 - royalsocietypublishing.org
Aposematism, the use of conspicuous colours to advertise unpalatability to predators, is
perhaps the most studied signalling system in nature. However, its evolutionary stability …

Automimic frequency influences the foraging decisions of avian predators on aposematic prey
J Skelhorn, C Rowe - Animal Behaviour, 2007 - Elsevier
Avian predators learn to avoid defended insects on the basis of their conspicuous warning
coloration. In many aposematic species, the level of chemical defence varies, with some …

" Go-slow" Signalling and the Problem of Automimicry
T Guilford - Journal of Theoretical Biology, 1994 - Elsevier
Automimicry is the existence of palatable individuals in an unpalatable, warningly coloured
(ie aposematic) prey species. Because automimics are visually indistinguishable from their …

Linking the evolution and form of warning coloration in nature
Many animals are toxic or unpalatable and signal this to predators with warning signals
(aposematism). Aposematic appearance has long been a classical system to study predator …

The complex business of survival by aposematism
The theory of warning signals dates back to Wallace but is still confusing, controversial and
complex. Because predator avoidance of warningly coloured prey (aposematism) is based …

Dietary conservatism may facilitate the initial evolution of aposematism
It has generally been assumed that warningly coloured organisms pay a cost associated
with their increased visibility, because naïve predators notice and eat them. This cost is …

In paired preference tests, domestic chicks innately choose the colour green over red, and the shape of a frog over a sphere when both stimuli are green
Many animals express unlearned colour preferences that depend on the context in which
signals are encountered. These colour biases may have evolved in response to the …

A role for phenotypic plasticity in the evolution of aposematism
GA Sword - Proceedings of the Royal Society of London …, 2002 - royalsocietypublishing.org
The evolution of warning coloration (aposematism) has been difficult to explain because
rare conspicuous mutants should suffer a higher cost of discovery by predators relative to …

Taste-rejection by predators and the evolution of unpalatability in prey
J Skelhorn, C Rowe - Behavioral Ecology and Sociobiology, 2006 - Springer
