The Earliest Known Radiation of Pitheciine Primates. [PDF]

open access: yesAm J Primatol
Right mandible and dentition of the holotype of Soriacebus ameghinorum (MACN Pv SC2), from the Early Miocene of Patagonia, compared with the living Cacajao calvus (FMNH 88813, cast), both representing extinct and extant morphologies of the Pitheciinae: Procumbent and styliform incisors and projecting canines represent a morphological complex for ...

Retrotransposon mapping in spider monkey genomes of the family Atelidae (Platyrrhini, Primates) shows a high level of LINE-1 amplification

open access: yesJournal of Biological Research, 2022
To investigate the distribution of LINE-1 repeat sequences, a LINE-1 probe was Fluorescence In Situ Hybridized (FISH) on the chromosomes of Ateles geoffroyi and Ateles fusciceps (Atelidae); a LINE-1 probe was also mapped on Cebuella pygmaea (Cebidae ...

New records and confirmation of the presence of three species of primates (Mammalia, Primates) in southwestern Colombia [PDF]

open access: yesCheck List, 2020
Cebus albifrons (Humboldt, 1812); Sapajus apella (Linnaeus, 1758) and Aotus lemurinus I. Geoffroy, 1843 are widely distributed primates in Colombia. Despite this, there are gaps in the occurrence of these species in the southwestern part of the country ...

Incisor cross-sectional area at the cementoenamel junction correlates with an increased reliance on frugivory in anthropoid primates. [PDF]

open access: yesAnat Rec (Hoboken)
Abstract Diet is one of a limited set of key ecological parameters defining primate species. A detailed understanding of dental functional correlates with primate diet is a key component for accurate dietary inference in fossil primates. Although considerable effort has been devoted to understanding post‐canine dental function, incisor function remains

A RAD-sequencing approach to genome-wide marker discovery, genotyping, and phylogenetic inference in a diverse radiation of primates. [PDF]

open access: yesPLoS ONE, 2018
Until recently, most phylogenetic and population genetics studies of nonhuman primates have relied on mitochondrial DNA and/or a small number of nuclear DNA markers, which can limit our understanding of primate evolutionary and population history.

Characterization of Stone Tool Use in Wild Groups of Critically Endangered Yellow-Breasted Capuchin Monkeys (Sapajus xanthosternos). [PDF]

open access: yesAm J Biol Anthropol
First camera trap video footage for wild Sapajus xanthosternos cracking resistant nuts with stone tools. ABSTRACT Objectives A hallmark of hominin evolution is the advent and diversification of stone tool use, and biological anthropologists have a particular interest in characterizing tool use behaviors in different hominin species.

Phylogenetics and an updated taxonomic status of the Tamarins (Callitrichinae, Cebidae)

open access: greenMolecular Phylogenetics and Evolution, 2022
Traditionally, Saguinus has been organized into six taxonomic groups: bicolor, inustus, midas, mystax, nigricollis, and oedipus. After recent revisions, taxonomic reclassifications were proposed, including (1) the recognition of Leontocebus as a new genus, and (2) the subdivision of Saguinus into three subgenera.

Phylogenetic inferences of Atelinae (Platyrrhini) based on multi-directional chromosome painting in Brachyteles arachnoides, Ateles paniscus paniscus and Ateles b. marginatus [PDF]

open access: yes, 2005
We performed multi-directional chromosome painting in a comparative cytogenetic study of the three Atelinae species Brachyteles arachnoides, Ateles paniscus paniscus and Ateles belzebuth marginatus, in order to reconstruct phylogenetic relationships ...

A new karyotype inCallicebus Torquatus(Cebidae, Primates) [PDF]

open access: yesHereditas, 2000
We describe a new karyotype of Callicebus torquatus using conventional staining, G-banding with Wright Stain, CBG, Ag-NOR staining and fluorescence in situ hybridization (FISH) with human telomere probes and comparative analysis with the previously reported karyotype of C. torquatus torquatus (2n = 20).
