Ateles spp. and Alouatta spp. are often sympatric, and although they are mainly frugivorous and folivorous, respectively, they consume some of the same fruit species. However, they differ in terms of color vision, which is thought to be important for fruit detection. Alouatta spp. have routine trichromatic color vision, while Ateles spp. presents the classic polymorphism of platyrrhines: heterozygous females have trichromatic color vision, and males and homozygous females have dichromatic… 

Visual detection and fruit selection by the mantled howler monkey (Alouatta palliata)

The findings suggest that routine trichromatic color vision may aid in the detection and discrimination of conspicuously colored fruits, but that the final decision whether to accept or reject a fruit probably involves the use of other senses in addition to vision.

Detection of fruit by the Cerrado's marmoset (Callithrix penicillata): modeling color signals for different background scenarios and ambient light intensities.

Differential performances of trichromatic phenotypes, together with overdominance selection, seem to explain the maintenance of the tri-allelic system found in callitrichids.

The Behavioral Ecology of Color Vision: Considering Fruit Conspicuity, Detection Distance and Dietary Importance

The results are consistent with the hypothesis that long-distance detection of fruit patches exerts a selective pressure on trichromacy in neotropical primates, and suggest that greenish-brownish fruits might have played an underappreciated role in the evolution of primate color vision.

Color Vision Variation and Foraging Behavior in Wild Neotropical Titi Monkeys (Callicebus brunneus): Possible Mediating Roles for Spatial Memory and Reproductive Status

It is proposed that a trichromatic advantage for foraging primates may be realized only when individuals’ energy requirements warrant searching for nonmemorable YOR food patches, a context for selection considerably more limited than is often assumed in explanations of the evolution of primate color vision.

Effect of color vision phenotype on the foraging of wild white-faced capuchins, Cebus capucinus

Analysis of C. capucinus foraging behavior shows that trichromats do not differ from dichromats in their fruit or energy acquisition rates, demonstrating the importance of using a fitness currency that is relevant to individual animals to test evolutionary hypotheses.

Influência da visão de cores na detecção de frutos, flores e invertebrados em grupos de Callithrix jacchus na Caatinga

Analysis of chromatic contrasts showed that trichromat phenotypes have superior fruit detection performance, while as insect detection is concerned, all phenotypes are equally able to detect insects.

Importance of Achromatic Contrast in Short-Range Fruit Foraging of Primates

The results suggest that luminance contrast can serve as an important cue in short-range foraging attempts despite other sensory cues that could be available and the advantage of red-green color vision in primates may not be as salient as previously thought.

Primate Fruit Color: Useful Concept or Alluring Myth?

It is concluded that identifying the importance of primate seed dispersers in shaping fruit visual traits is possible, but more complex than previously thought.

Can color vision variation explain sex differences in invertebrate foraging by capuchin monkeys

It is found that some variation in invertebrate foraging reflects differences between the sexes that may be due to disparities in size, strength, reproductive demands or niche preferences, but other intraspecific variation in foraging that might be mistakenly attributed to sex differences actually reflects differences in color vision.



Do female tamarins use visual cues to detect fruit rewards more successfully than do males?

It is concluded that trichromatic vision in female tamarins does not confer an advantage for detecting yellow fruit rewards against mature foliage.

Fruits, foliage and the evolution of primate colour vision.

It is reported that particular trichromatic platyrrhine phenotypes may be better suited than others to foraging for particular fruits under particular conditions of illumination, and possible explanations for the maintenance of polymorphic colour vision amongst the platyr rhines are discussed.

The effect of colour vision status on the detection and selection of fruits by tamarins (Saguinus spp.)

This is the first time that a trichromatic foraging advantage has been demonstrated for monkeys using naturalistic stimuli with the same chromatic properties as those encountered by wild animals.

Massive Destruction of Symphonia globulifera (Clusiaceae) Flowers by Central American Spider Monkeys (Ateles geoffroyi) 1

The results suggest that some primates may play an important role in floral herbivory in tropical forests and the subsequent reduction in reproductive success in Ateles geoffroyi.

The feeding preferences of howler monkeys at their northernmost distribution in the Neotropics are reported for an annual cycle. A remarkable selectivity for 27 species representing 15 families was

Catarrhine photopigments are optimized for detecting targets against a foliage background.

By treating the task of searching for food as a signal-detection task, it is shown that, of all possible combinations of cone sensitivities, the spectral positions of the actual primate pigments are optimal for finding fruit or young leaves against the background of mature leaves.

Fruit eating and seed dispersal by howling monkeys (Alouatta palliata) in the tropical rain forest of Los Tuxtlas, Mexico

Howling monkeys created diverse seed shadows in the vicinity of their leaf and fruit sources, and while they dispersed the seeds of some plant species, they also produced a great deal of fruit and seed waste for others.

Habitat preferences, diet, feeding strategy and social organization of the black spider monkey (ateles paniscus paniscus linnaeus 1758) in surinam

This monograph reports on a 26 month socioecological study of black spider monkeys in the Raleigh-vallen — Voltzberg Nature Reserve, Surinam, and clarifies the complex temporal and spatial effects of tropical rain forest food sources on the behavior of a group of spider monkeys.

Chromaticity as a signal of ripeness in fruits taken by primates.

By calculating which set of possible photopigments would maximise the chromatic distance between samples of each fruit species, it is shown that the spectral positions of the primate long- and middle-wavelength cone pigments are not optimised for this task.
