Chromosomal distribution of interstitial telomeric sequences in nine neotropical primates (Platyrrhini): possible implications in evolution and phylogeny [PDF]

open access: yes, 2016
To localize interstitial telomeric sequences (ITSs) and to test whether their pattern of distribution could be linked to chromosomal evolution, we hybridized telomeric sequence probes (peptide nucleic acid, PNA) on metaphases of New World monkeys ...

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 ...

A phylogenomic perspective on the robust capuchin monkey (Sapajus) radiation : first evidence for extensive population admixture across South America [PDF]

open access: yes, 2018
Phylogenetic relationships amongst the robust capuchin monkeys (genus Sapajus) are poorly understood. Morphology-based taxonomies have recognized anywhere from one to twelve different species.

Sperm Morphology in Neotropical Primates

open access: yesAnimals, 2019
The morphological and morphometric characterization of spermatozoa has been used as a taxonomic and phylogenetic tool for different species of mammals. We evaluated and compared the sperm morphometry of five neotropical primate species: Alouatta caraya ...

Multiple sex chromosome systems in howler monkeys (Platyrrhini, Alouatta) [PDF]

open access: yes, 2014
In light of the multiple sex chromosome systems observed in howler monkeys (Alouatta Lacépède, 1799) a combined cladistic analysis using chromosomal and molecular characters was applied to discuss the possible origin of these systems.

Phylogeny, molecular dating and zoogeographic history of the titi monkeys (Callicebus, Pitheciidae) of eastern Brazil [PDF]

open access: yes, 2018
The titi monkeys belong to a genus of New World primates endemic to South America, which were recently reclassified in three genera (Cheracebus, Plecturocebus and Callicebus).

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.

Life‐History Correlates of Enamel Microstructure in Cebidae (Platyrrhini, Primates) [PDF]

open access: yesThe Anatomical Record, 2011
AbstractPrevious studies have examined tooth eruption as it relates intrinsically to body mass, brain mass, and other life history variables, and extrinsically to ecological factors (e.g., age at foraging independence, environmental risk aversion, and maternal investment).

Divergence Times and the Evolutionary Radiation of New World Monkeys (Platyrrhini, Primates): An Analysis of Fossil and Molecular Data [PDF]

open access: yes, 2013
The estimation of phylogenetic relationships and divergence times among a group of organisms is a fundamental first step toward understanding its biological diversification.
