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 ...

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 ReportsWhile 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.

Size Disparity in Putative Primate Adaptive Radiations and Other Mammalian Clades. [PDF]
Am J Biol AnthropolABSTRACT 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

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.

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

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.

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

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-

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