Animal colours commonly act as signals for mates or predators. In many damselfly species,
both sexes go through a developmental colour change as adults, and females often show …

Predation has been a major driver of the evolution of prey species, which consequently
develop antipredator adaptations. However, little is known about the genetic basis …

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 …

Abstract Dromaeosaurids (Theropoda: Dromaeosauridae), a group of dynamic, swift
predators, have a sparse fossil record, particularly at the time of their extinction near the …

Male calopterygid damselflies often exhibit colourful wings used during aggressive contests
and courtship displays. Evidence suggests that male wing coloration is a secondary sexual …

Incomplete premating barriers in closely related species may result in reproductive
interference. This process has different fitness consequences and can lead to three …

Conspicuous female coloration can evolve through male mate choice or via female-female
competition thereby increasing female mating success. However, when mating is not …

Bright iridescent colours are widespread in several aquatic and terrestrial animal taxa and
are usually involved in intraspecific communication and/or predator avoidance. Camouflage …

Wing coloration is a very ancient feature among insects. Even the wings of the oldest known
Pterygota showed transverse colored bands involved in a putative disruptive function …

Colorful feathers have long been assumed to be conspicuous to predators, and hence likely
to incur costs due to enhanced predation risk. However, many mammals that prey on birds …
