The visual displays of animals and plants are often colourful, and colour vision allows
animals to respond to these signals as they forage for food, choose mates and so-forth. This …

We investigate the hypothesis that colour vision in primates was selected for discriminating
the spectral modulations on the skin of conspecifics, presumably for the purpose of …

Somewhere in Africa, more than a million years ago, a line of apes began to rear their young
differently than their Great Ape ancestors. From this new form of care came new ways of …

Coloration is a diagnostic tool for identifying mammals, but inquiry into its function has lain
dormant for almost a century. Recently, the topic has been revived and modern phylogenetic …

Current hypotheses that use visually guided reaching and grasping to explain orbital
convergence, visual specialization, and brain expansion in primates are open to question …

The avian plumage color gamut is the complete range of plumage colors, as seen by birds
themselves. We used a tetrahedral avian color stimulus space to estimate the avian …

Here I survey, collate and synthesize contrasting coloration in 5000 species of terrestrial
mammals focusing on black and white pelage. After briefly reviewing alternative functional …

For more than a century, the blue structural colours of mammalian skin have been
hypothesized to be produced by incoherent, Rayleigh or Tyndall scattering. We investigated …

Abstract Flip through The Pictorial Guide to the Living Primates1 and you will notice a
striking yet generally underappreciated aspect of primate biology: primates are extremely …

Primates are noted for their varied and complex pelage and bare skin coloration but the
significance of this diverse coloration remains opaque. Using new updated information …
