Efecto nutricional sobre el crecimiento craneofacial de Saimiri Sciureus (CEBIDAE)

Revista Argentina de Antropología Biológica, 1996
Diez machos Saimiri sciureus (CEBIDAE), nacidos en el Centro Argentino de Primates (CAPRIM), fueron divididos a partir del destete (6 meses de edad), en un grupo de cinco controles, alimentados ad libitum con dieta semisintética con 20% de proteínas y ...

Incisor cross-sectional area at the cementoenamel junction correlates with an increased reliance on frugivory in anthropoid primates. [PDF]

Anat Rec (Hoboken)
Abstract Diet is one of a limited set of key ecological parameters defining primate species. A detailed understanding of dental functional correlates with primate diet is a key component for accurate dietary inference in fossil primates. Although considerable effort has been devoted to understanding post‐canine dental function, incisor function remains

Characterization of Stone Tool Use in Wild Groups of Critically Endangered Yellow-Breasted Capuchin Monkeys (Sapajus xanthosternos). [PDF]

Am J Biol Anthropol
First camera trap video footage for wild Sapajus xanthosternos cracking resistant nuts with stone tools. ABSTRACT Objectives A hallmark of hominin evolution is the advent and diversification of stone tool use, and biological anthropologists have a particular interest in characterizing tool use behaviors in different hominin species.

A new karyotype inCallicebus Torquatus(Cebidae, Primates) [PDF]

Hereditas, 2000
We describe a new karyotype of Callicebus torquatus using conventional staining, G-banding with Wright Stain, CBG, Ag-NOR staining and fluorescence in situ hybridization (FISH) with human telomere probes and comparative analysis with the previously reported karyotype of C. torquatus torquatus (2n = 20).

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.

Cebus apella (Primata: Cebidae) as a new host for Fonsecalges johnjadini (Acari: Psoroptidae, Cebalginae) with a description of anatomopathological aspects

Memorias do Instituto Oswaldo Cruz, 2001
Mites collected from the auditory canal of Cebus apella (capuchin monkey), family Cebidae, were identified as Fonsecalges johnjadini (Psoroptidae, Cebalginae). It is the first record of this parasite from this monkey. This paper emphasizes the importance

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 ...
