The sugar composition of fruits in the diet of spider monkeys (Ateles geoffroyi) in tropical humid forest in Costa Rica [PDF]

open access: yes, 2003
Spider monkeys (Ateles geoffroyi) detect sucrose at a threshold lower than any primate yet tested and prefer sucrose to glucose or fructose in laboratory tests.

Pinworms of the red howler monkey (Alouatta seniculus) in Colombia. Gathering the pieces of the pinworm-primate puzzle [PDF]

open access: yes, 2020
Pinworms of primates are believed to be highly host specific parasites, forming co-evolutionary associations with their hosts. In order to assess the strength and reach of such evolutionary links, we need to have a broad understanding of the pinworm ...

Chromosome polymorphism in Ateles geoffroyi (Cebidae; Primates; Mammalia)

open access: yesTheoretical and Applied Genetics, 1992
The karyotype of Ateles geoffroyi (Cebidae; Primates; Mammalia) was studied using G- and C-banding techniques, and standardized idiograms are proposed. A polymorphism of chromosome 3 due to a pericentric inversion has been identified for the first time. Genetic analysis of this polymorphism showed Mendelian inheritance.

Differential fruit choice in two simpatric monkey species and frugivorous bats in southern Mexico

open access: yesActa Biológica Colombiana, 2018
In order to identify the role played by plant species as a food source in the fruit election of dispersing agents (Alouatta pigra Lawrence 1933, Ateles geoffroyi Kuhl 1820 and frugivorous bats), we developed a study in dry tropical forests in Yucatan ...

Patterns of MHC-G-Like and MHC-B Diversification in New World Monkeys. [PDF]

open access: yesPLoS ONE, 2015
The MHC class I (MHC-I) region in New World monkeys (Platyrrhini) has remained relatively understudied. To evaluate the diversification patterns and transcription behavior of MHC-I in Platyrrhini, we first analyzed public genomic sequences from the MHC-G-

ASPM and the evolution of cerebral cortical size in a community of New World monkeys.

open access: yesPLoS ONE, 2012
The ASPM (abnormal spindle-like microcephaly associated) gene has been proposed as a major determinant of cerebral cortical size among primates, including humans.

Universal behaviors as candidate traditions in wild spider monkeys. [PDF]

open access: yesPLoS ONE, 2011
Candidate traditions were documented across three communities of wild spider monkeys (Ateles geoffroyi) using an a priori approach to identify behavioral variants and a statistical approach to examine differences in their proportional use.

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

open access: yesThe Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

Fruit Availability and Maternal Energy Expenditure Associated With Infant Independence in an Arboreal Primate (Colobus angolensis ruwenzorii). [PDF]

open access: yesAm J Primatol
Infant being handled by mother. ABSTRACT A range of ecological and social factors have been shown to affect early‐life behaviour in mammals. Primate infants are altricial and thus unable to move independently at birth. As a result, infants in some species are continuously held or carried (handled) by their mother or another caregiver (allomother ...

The effect of food provisioning on the nutrient intake of wild and captive primates : implications for the conservation management of wild and captive populations : a thesis presented in partial fulfilment of the requirements for the degree of Doctorate of Philosophy in Ecology, Massey University, Albany, New Zealand [PDF]

open access: yes, 2017
Many non-human primate populations worldwide are threatened with extinction. Various measures are taken to save these species. Amongst these efforts are habitat protection, restoration, and public education, including wildlife tourism.
