Aposematic signals are often characterized by high conspicuousness. Larger and brighter
signals reinforce avoidance learning, distinguish defended from palatable prey and are …

Vision is a vital attribute to foraging, navigation, mate selection and social signalling in
animals, which often have a very different colour perception in comparison to humans. For …

Many taxa use conspicuous colouration to attract mates, signal chemical defences
(aposematism) or for thermoregulation. Conspicuousness is a key feature of aposematic …

Lepidoptera is one of the most diverse orders of insects, their larvae are very abundant in
many habitats, and frequent prey of various predators. To decrease predation risk …

The eggs of oviparous species are often subject to intense predation pressure. One parental
strategy to deter predators is to produce eggs that are laced with noxious chemicals and are …

Warning coloration and Batesian mimicry are classic examples of Darwinian evolution, but
empirical evolutionary patterns are often paradoxical. We test whether foraging costs predict …

Colour is an important component of many different defensive strategies, but signal efficacy
and detectability will also depend on the size of the coloured structures, and how pattern …

This research examined the joint influence of emotion expression (pride vs. shame) and
color (red vs. blue) on female and male perceptions of the attractiveness and social position …

1. Birds are considered to be the primary selective agents for warning colouration in
butterflies, and select for aposematic mimicry by learning to avoid brightly coloured prey …

'Motion dazzle camouflage'is the name for the putative effects of highly conspicuous, often
repetitive or complex, patterns on parameters important in prey capture, such as the …
