Colour constancy is the tendency of objects to appear the same colour even under changing
illumination. A yellow banana appears yellow whether you see it in the tungsten light of the …

Those taking an evolutionary approach to the behavioral, cognitive, and social sciences
have been emphasizing the natural selection of mechanisms and strategies that are specific …

Organisms frequently gain advantages when they engage in signalling with individuals of
other species. Here, we provide a functionally structured framework of the great variety of …

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 …

Animal coloration patterns, from zebra stripes to bird egg speckles, are remarkably varied.
With research on the perception, function, and evolution of animal patterns growing rapidly …

The agnathans (lampreys and hagfishes) are representatives of the jawless fishes and
constitute the first lineage of extant vertebrates to evolve within chordate phylogenetic …

Here, I suggest that colour polymorphic study systems have been underutilized to answer
general questions about evolutionary processes, such as morph frequency dynamics …

In recent years, colour-vision abilities have been rather generously ascribed to various
invertebrates and even bacteria. This uncertainty of when to diagnose colour vision stems in …

The ability to change appearance over a range of timescales is widespread in nature,
existing in many invertebrate and vertebrate groups. This can include color change …

The dramatic colours of biological communication signals raise questions about how
animals perceive suprathreshold colour differences, and there are long-standing questions …
