Role of different colours of aposematic insects in learning, memory and generalization of naïve bird predators
Among the various properties of visual warning signals, colour seems to be especially
important for avian predators. We tested the role of particular colours of an aposematic …

Generalization and the evolution of symmetry preferences
M Enquist, RA Johnstone - Proceedings of the Royal …, 1997 - royalsocietypublishing.org
Biological displays are often symmetrical, and there is growing evidence that receivers are
sensitive to these symmetries. One explanation for the evolution of such sensitivity is that …

The evolution of egg clustering in butterflies: a test of the egg desiccation hypothesis
BR Clark, SH Faeth - Evolutionary Ecology, 1998 - Springer

Conspicuousness is correlated with toxicity in marine opisthobranchs
Aposematism is defined as the use of conspicuous colouration to warn predators that an
individual is chemically or otherwise defended. Mechanisms that drive the evolution of …

How the ladybird got its spots: effects of resource limitation on the honesty of aposematic signals
Prey species often possess defences (eg toxins) coupled with warning signals (ie
aposematism). There is growing evidence that the expression of aposematic signals often …

Experienced chicks show biased avoidance of stronger signals: an experiment with natural colour variation in live aposematic prey
G Gamberale-Stille, BS Tullberg - Evolutionary Ecology, 1999 - Springer
