Tool use in urban populations of capuchin monkeys Sapajus spp. (Primates: Cebidae)

Zoologia, 2014
Capuchin monkeys, Sapajus Kerr, 1792, are known for their flexible behavior, including tool use, and their ability to survive in urban forests. We observed capuchin juveniles using wood as hammer and anvil and different materials as sponges (four tool ...

Carcinoma mamário pouco diferenciado em macaco-prego, Cebus sp. (Cebidae) Mammary high-grade carcinoma in a monkey, Cebus sp. (Cebidae)

Pesquisa Veterinária Brasileira, 2013
As neoplasias mamárias são raras em primatas não humanos, enquanto que nas mulheres apresentam alta incidência. O objetivo deste trabalho foi relatar a ocorrência e os resultados do tratamento de um Cebus sp. (fam.

Mitochondrial DNA for Phylogeny Building: Assessing Individual and Grouped mtGenes as Proxies for the mtGenome in Platyrrhines. [PDF]

Am J Primatol
ABSTRACT Phylogenetic trees are analytic tools used in primate studies to elucidate evolutionary relationships. Because of its relative ease to sequence and rapid evolution compared to nuclear genomes, mitochondrial DNA is frequently used for phylogeny building. This project evaluated the effectiveness of using individual or grouped mitochondrial genes

Female Reproductive System Neoplasms in Neotropical Primates. [PDF]

J Med Primatol
ABSTRACT Background There are no previous descriptions of the prevalence of spontaneous female reproductive neoplasms in neotropical primates. Methods A 6‐year study of pathological records from the Anatomy Pathology Sector from the Federal Rural University of Rio de Janeiro (SAP/UFRuralRJ) was conducted.

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

Journal 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]

Check 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 ...

Unveiling the Evolutionary History of cis-Andean Alouatta (Atelidae, Alouattinae) Through Mitochondrial Genomes. [PDF]

Am J Primatol
Mitochondrial DNA analysis suggests that founder‐event speciation played a key role in the divergence between cis‐Andean and trans‐Andean clades, as well as in the diversification of cis‐Andean lineages. Ancestral range reconstruction using mitochondrial genomes indicates that the most recent common ancestor of Alouatta had a widespread distribution ...

The Earliest Known Radiation of Pitheciine Primates. [PDF]

Am 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 ...

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

PLoS 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.

Taxonomic status of Tamarinus imperator subgrisescens (Lönnberg, 1940) (Cebidae, Callitrichinae) [PDF]

Papéis Avulsos de Zoologia, 2023
The emperor tamarin, Tamarinus imperator, is composed of two subspecies, the nominal type, T. i. imperator, distributed between the Acre and Purus Rivers, whose range is limited between the Brazilian state of Acre and Peru are unbounded, and T.
