Size Disparity in Putative Primate Adaptive Radiations and Other Mammalian Clades. [PDF]

Am J Biol Anthropol
ABSTRACT Introduction Adaptive radiation is commonly viewed as the rapid production of phenotypic disparity and taxonomic diversity. Among primates, two clades have been identified as potential adaptive radiations: the lemurs of Madagascar and the platyrrhines of the Americas. This study examines these clades for one of the proposed signals of adaptive

Synteny of human chromosomes 14 and 15 in the platyrrhines (Primates, Platyrrhini) [PDF]

Genetics and Molecular Biology, 2009
In order to study the intra- and interspecific variability of the 14/15 association in Platyrrhini, we analyzed 15 species from 13 genera, including species that had not been described yet. The DNA libraries of human chromosomes 14 and 15 were hybridized

Hominoid-specific calretinin-immunopositivity of the optic radiation (geniculocalcarine tract). [PDF]

Anat Rec (Hoboken)
Calretinin‐immunostained coronal section through the primary (V1) and extrastriate (ExSt) cortex of the lar gibbon. Note that the optic radiation (OR) is strongly calretinin‐immunoreactive. This calretinin‐immunopositivity of the OR distinguishes the Hominoidea from other primates in terms of the neurochemistry of the OR.

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.

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

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 ...

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 ...
