Trichromatic colour vision in New World monkeys
Nature, 1996Trichromatic colour vision depends on the presence of three types of cone photopigment. Trichromacy is the norm for all Old World monkeys, apes and humans, but in several genera of New World monkeys, colour vision is strikingly polymorphic. The difference in colour vision between these New and Old World primates results form differing arrangements of ...

International Journal of Primatology, 2007
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 exploit these sources of information. Unlike the catarrhines, platyrrhines typically have sex-linked polymorphic color vision that provides individuals with any of several distinct ...

Arboreal locomotion in small New-World monkeys
Zeitschrift für Morphologie und Anthropologie, 2002The postural and locomotor activity and its relation to substrates was observed in 3 Saguinus oedipus, and 3 Saimiri sciureus for comparison, during a period of 10 h for each individual. The animals moved freely in cages of 3.40 m x 3.40 m x 2.40 m (height) on rather diverse substrates.

Adrenergic retinal neurons of some new world monkeys
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1969The retina of Aotes monkeys, Cebus monkeys, squirrel monkeys, and marmosets were investigated. Adrenergic perikarya were found in the innermost cell rows of the inner nuclear layer of all the investigated species. In addition, the Cebus monkey was found to have a special type of adrenergic neurons in the inner nuclear layer.

Toxoplasmosis in a colony of New World monkeys
Veterinary Parasitology, 1997In a colony of New World monkeys five tamarins (Saguinus oedipus, Saguinus labiatus and Leontopithecus rosal. rosal.), three marmosets (Callithrix jacchus and Callithrix pygmaea) and one saki (Pithecia pithecia) died suddenly. The colony comprised 16 marmosets, 10 tamarins and three sakis.

Vocal communication in New World monkeys
Journal of Human Evolution, 1989Abstract Many features of the vocal communication systems of New World primates are similar to the most complex vocal systems known: human speech and bird song. This paper reviews the parallels between vocal communication in New World monkeys and phenomena of bird song and human speech.

Evolution of feeding niches in new world monkeys
American Journal of Physical Anthropology, 1992AbstractThe adaptive radiation of modern New World monkeys unfolded as the major lineages diversified within different dietary‐adaptive zones predicated upon a fundamentally frugivorous habit. The broad outlines of this pattern can be seen in the fossil record, beginning in the early Miocene. Cebids are obligate frugivorous predators.
