Effect of polymorphic colour vision for fruit detection in the spider monkey Ateles geoffroyi, and its implications for the maintenance of polymorphic colour vision in platyrrhine monkeys [PDF]

open access: yes, 2004
Most platyrrhine monkeys have an X-linked tri-allelic polymorphism for medium and long wavelength (M/L) sensitive cone photopigments. These pigments' sensitivity maxima (λmax) range from 535 to 562 nm.

The comparative and functional anatomy of the forelimb muscle architecture of Humboldt's woolly monkey (Lagothrix lagotricha)

open access: yesThe Anatomical Record, Volume 307, Issue 12, Page 3850-3869, December 2024.
Abstract Humboldt's woolly monkey (Lagothrix lagortricha) is a ceboid primate that more frequently engages in plantigrade quadrupedalism (~89%) but is, like most other members of the subfamily Atelinae, capable of suspensory postures and “tail assisted” brachiation.

Assessing the gut microbiome and the influence of host genetics on a critically endangered primate, the northern muriqui (Brachyteles hypoxanthus)

open access: yesEnvironmental DNA, Volume 6, Issue 3, May–June 2024.
Analyses of the microbiome of the critically endangered muriqui revealed the importance of host genetics on the microbiome and suggested that social groups, despite being isolated by environmental barriers, host a similar microbiome composition. Abstract The Northern muriqui (Brachyteles hypoxanthus) is one of the world's most critically endangered ...

Reproductive physiology with emphasis on endometrial cycles of woolly and uakari monkeys—A literature review

open access: yesAmerican Journal of Primatology, Volume 86, Issue 2, February 2024.
Woolly monkeys and uakaries are vulnerable to the anthropic impacts due to their slower reproductive activity compared to other Neotropical primates. There is limited information available on the female reproductive physiology of these species. Although blood clots and endometrial desquamation were not observed, the presence of a menstrual cycle is not
