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 ...

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.

The current status of the New World monkey phylogeny

Anais da Academia Brasileira de Ciências, 2000
Four DNA datasets were combined in tandem (6700 bp) and Maximum parsimony and Neighbor-Joining analyses were performed. The results suggest three groups emerging almost at the same time: Atelidae, Pitheciidae and Cebidae.
