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 primates.

Do saki monkeys possess a grooming claw? [PDF]
Primate Biology, 2020 The presence of a grooming claw on the second toe is a characteristic of Strepsirrhini and tarsiers. There is also some evidence for the presence of a grooming claw in Platyrrhini.

Comparative gastrointestinal organ lengths among Amazonian primates (Primates: Platyrrhini)
American Journal of Biological Anthropology, 2023 AbstractObjectivesThe morphological features of the gastrointestinal tract (GIT) in mammals reflect a species' food niche breadth and dietary adaptations. For many wild mammals, the relationship between the structure of the GIT and diet is still poorly understood, for example, the GIT for frugivorous primates is usually classified as unspecialized and ...

Molecular Evidence Supports Five Lineages within Chiropotes (Pitheciidae, Platyrrhini)
Genes, 2023 Pitheciines have unique dental specializations among New World monkeys that allow them to feed on fruits with hard pericarps, thus playing a major role as seed predators. The three extant pitheciine genera, Pithecia, Cacajao and Chiropotes, are all endemic to the Amazon region. Because of the uncertainties about interspecific relationships, we reviewed

But how does it smell? An investigation of olfactory bulb size among living and fossil primates and other euarchontoglirans. [PDF]
Anat Rec (Hoboken)Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).

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.

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 ...

The origin of the RB1 imprint. [PDF]
PLoS ONE, 2013 The human RB1 gene is imprinted due to a differentially methylated CpG island in intron 2. This CpG island is part of PPP1R26P1, a truncated retrocopy of PPP1R26, and serves as a promoter for an alternative RB1 transcript.
