Climatic niche evolution in New World monkeys (Platyrrhini).

PLoS ONE, 2013
Despite considerable interest in recent years on species distribution modeling and phylogenetic niche conservatism, little is known about the way in which climatic niches change over evolutionary time.

Endocranial shape variation and allometry in Euarchontoglires [PDF]

Scientific Reports
While brain size in primates and their relatives within Euarchontoglires is well-studied, less research has examined brain shape, or the allometric trajectories that underlie the relationship between size and shape.

Pairing and recombination features during meiosis in Cebus paraguayanus (Primates: Platyrrhini) [PDF]

BMC Genetics, 2009
Background Among neotropical Primates, the Cai monkey Cebus paraguayanus (CPA) presents long, conserved chromosome syntenies with the human karyotype (HSA) as well as numerous C+ blocks in different chromosome pairs. In this study, immunofluorescence (IF)

Incidental Detection of Microfilariae in Saguinus bicolor and Saguinus midas From Central Amazon. [PDF]

J Med Primatol
ABSTRACT Callitrichid primates Saguinus bicolor and Saguinus midas from urban accidents in peri‐urban forests from Central Amazon were necropsied. Analysis of thoracic and peritoneal fluid showed that 56.5% (13/23) of S. bicolor individuals and 13.3% (4/30) of S.

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.

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

C-Cell Carcinoma in a Common Marmoset (Callithrix jacchus) With a Brief Review of Thyroid Neoplasms in Neotropical Primates. [PDF]

J Med Primatol
ABSTRACT A managed‐care female common marmoset developed a rare C‐cell carcinoma in the right thyroid lobe, characterized by capsular and intrathyroidal invasion. Neoplastic plasmacytoid cells arranged in sheets exhibited a morphological and immunophenotypic profile (calcitonin+, chromogranin A+, CK7+, INSM1+, TTF‐1) that closely resembles human ...

WHAT DO NEOTROPICAL PRIMATES TELL US UNDER THE LOOK OF CYTOGENETICS? [PDF]

BAG. Journal of Basic and Applied Genetics, 2022
Cytogenetics studies in Neotropical Primates (Primates: Platyrrhini) have shown that these mammals comprise a heterogeneous group at the chromosomal level.

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

PLoS 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-

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 ...
