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

The current status of the New World monkey phylogeny
Anais da Academia Brasileira de Ciências, 2000 Four DNA datasets were combined in tandem (6700 bp) and Maximum parsimony and Neighbor-Joining analyses were performed. The results suggest three groups emerging almost at the same time: Atelidae, Pitheciidae and Cebidae.

Characterization of Satellite DNAs in Squirrel Monkeys genus Saimiri (Cebidae, Platyrrhini) [PDF]
Scientific Reports, 2020 AbstractThe genusSaimiriis a decades-long taxonomic and phylogenetic puzzle to which cytogenetics has contributed crucial data. AllSaimirispecies apparently have a diploid number of 2n = 44 but vary in the number of chromosome arms. Repetitive sequences such as satellite DNAs are potentially informative cytogenetic markers because they display high ...

Effects of environmental perturbations during postnatal development on the phenotypic integration of the skull [PDF]
, 2011 Integration and modularity are fundamental determinants of how natural selection effects evolutionary change in complex multivariate traits. Interest in the study of the specific developmental basis of integration through experimental approaches is ...

Sperm Morphology in Neotropical Primates
Animals, 2019 The morphological and morphometric characterization of spermatozoa has been used as a taxonomic and phylogenetic tool for different species of mammals. We evaluated and compared the sperm morphometry of five neotropical primate species: Alouatta caraya ...

Chromosomal distribution of interstitial telomeric sequences in nine neotropical primates (Platyrrhini): possible implications in evolution and phylogeny [PDF]
, 2016 To localize interstitial telomeric sequences (ITSs) and to test whether their pattern of distribution could be linked to chromosomal evolution, we hybridized telomeric sequence probes (peptide nucleic acid, PNA) on metaphases of New World monkeys ...

Object grasping and manipulation in capuchin monkeys (genera Cebus and Sapajus) [PDF]
, 2018 The abilities to perform skilled hand movements and to manipulate objects dexterously are landmarks in the evolution of primates. The study of how primates use their hands to grasp and manipulate objects in accordance with their needs sheds light on how ...

A phylogenomic perspective on the robust capuchin monkey (Sapajus) radiation : first evidence for extensive population admixture across South America [PDF]
, 2018 Phylogenetic relationships amongst the robust capuchin monkeys (genus Sapajus) are poorly understood. Morphology-based taxonomies have recognized anywhere from one to twelve different species.

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

Phylogeny, molecular dating and zoogeographic history of the titi monkeys (Callicebus, Pitheciidae) of eastern Brazil [PDF]
, 2018 The titi monkeys belong to a genus of New World primates endemic to South America, which were recently reclassified in three genera (Cheracebus, Plecturocebus and Callicebus).
