What do we know about the heterochromatin of capuchin monkeys (Cebus: Platyrrhini)?
(Wiley Blackwell Publishing, Inc, 2018-01)
Cytogenetic studies in Cebus spp. have highlighted a peculiar genomic feature: the presence of conspicuous regions of extracentromeric heterochromatin distributed throughout the karyotype. This study investigates the ...

Cranial ontogeny and sexual dimorphism in two new world monkeys: Alouatta caraya (Atelidae) and Cebus apella (Cebidae)
(Wiley-liss, Div John Wiley & Sons Inc, 2011-06)
Pattern of skull development and sexual dimorphism was studied in Cebus apella and Alouatta caraya using univariate, bivariate, and multivariate statistics. In both species, sexual dimorphism develops because the common ...
Diversidad morfológica mandibular de los monos capuchinos: un análisis morfométricoMorphological diversity of the mandible of capuchin monkeys: a morphometric analysis
(Asociación de Antropología Biológica Argentina, 2018-06)
La diversificación de los platirrinos a escala macroevolutiva ha sido sistemáticamente estudiada en años recientes. Sin embargo, el origen de la diversidad fenotípica y de taxones observada a escalas filogenéticas menores, ...
A comparative study of the recombination pattern in three species of Platyrrhini monkeys (primates)
(Springer, 2011-10)
Homologous chromosomes exchange genetic information through recombination during meiotic synapsis, a process that increases genetic diversity and is fundamental to sexual reproduction. Meiotic studies in mammalian species ...
Primate research and conservation in northern Argentina: the field station Corrientes (Estación Biológica de Usos Múltiples – EBCo)
(Tropical Conservation Science, 2008-12)
En Argentina encontramos cinco especies de primates: Alouatta guariba and Aotus Azarai Alouatta caraya, Cebus nigritus, and Cebus paraguayanus. Dos especies se encuentran en peligro de extinción (A. guariba and A. azarai). ...
Primates sin frontera: una visión desde la citogenética evolutiva
(Sociedad Argentina de Genética, 2010-12)
Estudiar las características de variabilidad genética, organización social y biogeografía, permite nuevas interpretaciones del proceso especiogénico. En Primates en particular, en los 80, se desarrollan los primeros estudios ...
New primate genus from the Miocene of Argentina
(National Academy of Sciences, 2006-03)
Killikaike blakei is a new genus and species of anthropoid from the late Early Miocene of southeastern Argentina based on the most pristine fossil platyrrhine skull and dentition known so far. It is part of the New World ...
Meiosis and Chromosome Painting of Sex Chromosome Systems in Ceboidea
(Wiley-liss, div John Wiley & Sons Inc., 2001-02)
The identity of the chromosomes involved in the multiple sex system of Alouatta caraya (Aca) and the possible distribution of this system among other Ceboidea were investigated by chromosome painting of mitotic cells from ...
