Evidence for a peak-shift in predator generalization among aposematic prey

G Gamberale, BS Tullberg - Proceedings of the Royal …, 1996 - royalsocietypublishing.org
A previous theoretical model involving learning psychology and game theory has suggested
how warning coloration in unprofitable prey could evolve and become stable. The model …

Hidden preferences and the evolution of signals

A Arak, M Enquist - … Transactions of the Royal Society of …, 1993 - royalsocietypublishing.org
Mechanisms concerned with the recognition of biological signals act as important agents of
selection on the appearance or 'form'of signals. Recognition of a given signal form can be …

Role of different colours of aposematic insects in learning, memory and generalization of naïve bird predators

K Svádová, A Exnerová, P Štys, E Landová, J Valenta… - Animal Behaviour, 2009 - Elsevier
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 …

Biases in signal evolution: learning makes a difference

C Ten Cate, C Rowe - Trends in ecology & evolution, 2007 - cell.com
It is now well established that signal receivers have a key role in the evolution of animal
communication: the suite of sensory and cognitive processes by which animals perceive and …

Peak shift discrimination learning as a mechanism of signal evolution

SK Lynn, J Cnaani, DR Papaj - Evolution, 2005 - Wiley Online Library
Abstract “Peak shift” is a behavioral response bias arising from discrimination learning in
which animals display a directional, but limited, preference for or avoidance of unusual …

The evolution of egg clustering in butterflies: a test of the egg desiccation hypothesis

BR Clark, SH Faeth - Evolutionary Ecology, 1998 - Springer
Females of many insect species cluster their eggs. Egg clustering by lepidopteran species
usually results in aggregation of larvae that are more often conspicuously coloured and …

Conspicuousness is correlated with toxicity in marine opisthobranchs

F Cortesi, KL Cheney - Journal of Evolutionary Biology, 2010 - academic.oup.com
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

JD Blount, HM Rowland, FP Drijfhout… - Functional …, 2012 - Wiley Online Library
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
An important factor for understanding the evolution of warning coloration in unprofitable prey
is the synergistic effect produced by predator generalisation behaviour. Warning coloration …
