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.

Can I Have a Bite? The Influence of Infant Begging on Food Sharing in Capuchin Monkeys (Sapajus Libidinosus). [PDF]

Am J Primatol
Food sharing between mother and offspring in capuchin monkeys is a response to the infant's begging. Infants solicit more frequently high‐quality and hard‐to‐process foods and they are more likely to succeed when they are older and if the food item is not a lizard. ABSTRACT In primates, food sharing from mothers to infants may serve two main functions:

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 Vomeronasal Organ of New World Monkeys (Platyrrhini) [PDF]

The Anatomical Record, 2011
AbstractAlthough all platyrrhine primates possess a vomeronasal organ (VNO), few species have been studied in detail. Here, we revisit the microanatomy of the VNO and related features in serially sectioned samples from 41 platyrrhine cadavers (14 species) of mixed age.

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

, 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 ...

Investigation of marmoset hybrids (Cebuella pygmaea x Callithrix jacchus) and related Callitrichinae (Platyrrhini) by cross-species chromosome painting and comparative genomic hybridization [PDF]

, 2005
We report on the cytogenetics of twin offspring from an interspecies cross in marmosets (Callitrichinae, Platyrrhini), resulting from a pairing between a female Common marmoset (Callithrix jacchus, 2n = 46) and a male Pygmy marmoset (Cebuella pygmaea, 2n

Phylogenetic studies of the genus Cebus (Cebidae-Primates) using chromosome painting and G-banding

BMC Evolutionary Biology, 2008
Background Chromosomal painting, using whole chromosome probes from humans and Saguinus oedipus, was used to establish karyotypic divergence among species of the genus Cebus, including C. olivaceus, C. albifrons, C. apella robustus and C.

Taxonomic review of Saguinus mystax (Spix, 1823) (Primates, Callitrichidae), and description of a new species [PDF]

PeerJ, 2023
Although the Amazon has the greatest diversity of primates, there are still taxonomic uncertainties for many taxa, such as the species of the Saguinus mystax group.

Vertical clinging and leaping induced evolutionary rate shifts in postcranial evolution of tamarins and marmosets (Primates, Callitrichidae)

BMC Ecology and Evolution, 2021
Background Callitrichids comprise a diverse group of platyrrhine monkeys that are present across South and Central America. Their secondarily evolved small size and pointed claws allow them to cling to vertical trunks of a large diameter.

The Evolution of Primate Short-Term Memory [PDF]

Animal Behavior and Cognition, 2022
Short-term memory is implicated in a range of cognitive abilities and is critical for understanding primate cognitive evolution. To investigate the effects of phylogeny, ecology and sociality on short-term memory, we tested the largest and most diverse ...
