Assessing variation in animal coloration is difficult, as animals differ in their visual system
properties. This has led some to propose that human vision can never be used to evaluate …

Primates are unique among eutherian mammals for possessing three types of retinal cone.
Curiously, catarrhines, platyrrhines, and strepsirhines share this anatomy to different extents …

Primate color vision is well suited for investigating the genetic basis of foraging behavior
owing to a clear genotype–phenotype linkage. Finding fruits amid tropical foliage has long …

A prey may achieve camouflage through background matching and through disruptive
coloration. Background matching is based on visual similarity between the prey and its …

Colour change in animals can be adaptive phenotypic plasticity in heterogeneous
environments. Camouflage through background colour matching has been considered a …

Considering its widespread occurrence and importance in the animal kingdom, background
matching is clearly one of the most under-studied means of concealment. Background …

Midget retinal ganglion cells (RGCs) make up the majority of foveal RGCs in the primate
retina. The receptive fields of midget RGCs exhibit both spectral and spatial opponency and …

Trichromatic primates have a 'red-green'chromatic channel in addition to luminance and
'blue-yellow'channels. It has been argued that the red-green channel evolved in primates as …

The visual worlds of most primates are rich with potential color signals, and many
representatives of the order have evolved the biological mechanisms that allow them to …

Figs are important resources for frugivores, and Ficus is an ideal taxon for evaluating
patterns of primate foraging related to food color. Ficus spp. can be classified as …
