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

Comparative Cytogenetics, 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 ...

Chromosome Evolution in New World Monkeys (Platyrrhini) [PDF]

Cytogenetic and Genome Research, 2012
During the last decades, New World monkey (NWM, Platyrrhini, Anthropoideae) comparative cytogenetics has shed light on many fundamental aspects of genome organisation and evolution in this fascinating, but also highly endangered group of neotropical ...

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 ...

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 ...

Molecular phylogeny of the genus Saguinus (Platyrrhini, Primates) based on the ND1 mitochondrial gene and implications for conservation [PDF]

Genetics and Molecular Biology, 2005
The systematics of the subfamily Callitrichinae (Platyrrhini, Primates), a group of small monkeys from South America and Panama, remains an area of considerable discussion despite many investigations, there being continuing controversy over subgeneric ...

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.

Exploring the diversity of AVPR2 in Primates and its evolutionary implications [PDF]

Genetics and Molecular Biology, 2023
The current study focuses on the investigation of AVPR2 (VTR2C) protein-coupled receptor variants specific to different primate taxa. AVPR2 is activated by the neurohormone AVP, which modulates physiological processes, including water homeostasis.
