To understand the function of colour signals in nature, we require robust quantitative
analytical frameworks to enable us to estimate how animal and plant colour patterns appear …

To be effective, animal colour signals must attract attention—and therefore need to be
conspicuous. To understand the signal function, it is useful to evaluate their …

In many animals, ultraviolet (UV) vision guides navigation, foraging, and communication, but
few studies have addressed the contribution of UV signals to colour vision, or measured UV …

Animals use colour vision in a range of behaviours. Visual performance is limited by
thresholds, which are set by noise in photoreceptors and subsequent neural processing …

Achromatic (luminance) vision is used by animals to perceive motion, pattern, space and
texture. Luminance contrast sensitivity thresholds are often poorly characterised for …

Vision is used by animals to find food and mates, avoid predators, defend resources and
navigate through complex habitats. Behavioural experiments are essential for …

Parallel evolution, in which independent populations evolve along similar phenotypic
trajectories, offers insights into the repeatability of adaptive evolution. Here, we revisit a …

The ability to see ultraviolet (UV) light (< 400 nm) may have importance for foraging,
communication or navigation in many taxa including insects, crustaceans, fishes …

The presence of various combinations of adjacent colors within polymorphic species' color
pattern could have a major impact on mate choice. We studied the role of pattern geometry …

Bluelined goatfish (Upeneichthys lineatus) exhibit dynamic body colour changes and
transform rapidly from a pale, buff/white, horizontally banded pattern to a conspicuous …
