Molecular Phylogeny of the New World Monkeys (Platyrrhini, Primates)

Molecular Phylogenetics and Evolution, 1993
Phylogenetic relationships among the 16 extant genera of Ceboidea (the New World monkeys) were examined using aligned epsilon-globin gene sequences from 19 New World monkeys (representing all 16 extant ceboid genera), and seven catarrhines (one Old World monkey and six hominoids) and tarsier as the outgroups.

Molecular phylogenetics of howler monkeys (Alouatta, Platyrrhini)

Chromosoma, 2001
Molecular phylogenetic analyses of seven Brazilian Alouatta species, based on cytochrome b DNA sequence data were carried out. Parsimony and neighbor joining topologies grouped Alouatta belzebul and A. fusca as sister groups in one clade while another, well-supported clade contained A. seniculus as the most basal offshoot, followed by A. nigerrima as a

Recently amplified satellite DNA inCallithrix argentata (Primates, Platyrrhini)

Chromosome Research, 1995
A satellite DNA has been cloned from the neotropical primate Callithrix argentata and designated CarB. The presence of the satellite was assayed in New and Old World primates by blot hybridization: CarB is highly amplified in the genomes of all three species belonging to the C. argentata species group (C. argentata, C. emiliae, C.

Heterochromatin and cytogenetic polymorphisms in Cebus apella (Cebidae, Platyrrhini)

American Journal of Primatology, 1995
AbstractCytogenetic studies have been carried out in 39 specimens of C. apella of different origins. Three different morphologies, one affecting the long arm of chromosome 4 and two affecting pair 17, have been detected. In each case, they can be related by paracentric inversions.

Identification of MHC I class genes in two Platyrrhini species

American Journal of Primatology, 2015
The major histocompatibility complex is a diverse gene family that plays a crucial role in the adaptive immune system. In humans, the MHC class I genes consist of the classical loci of HLA‐A, ‐B, and ‐C, and the nonclassical loci HLA‐E, ‐F, and ‐G. In Platyrrhini species, few MHC class I genes have been described so far and were classified as MHC‐E ...

Paleobiogeographic Perspectives on the Origin of the Platyrrhini

1980
This chapter will explore the various hypotheses and scenarios that have been advanced concerning the paleobiogeographic source of origin of the Platyrrhini. The specific questions to be addressed include: (1) From what geographical region or regions were the immediate ancestors of the New World monkeys derived?

Systematics and evolution of the jacchus group of marmosets (Platyrrhini)

American Journal of Physical Anthropology, 2003
AbstractInterspecific differentiation and geographic variation patterns in 39 skull traits of eastern Brazilian marmosets are analyzed. EasternCallithrixtaxa are distinct morphologically, and no evidence of intergradation among taxa is observed. Instead, there are sharp, stepped morphological boundaries among taxa, consistent with species‐level ...

Geophagy in New World Monkeys (Platyrrhini): Ecological and Geographic Patterns

Folia Primatologica, 2008
Geophagy has been recorded in an increasing number of New World monkeys (Platyrrhini) over recent years, permitting a tentative analysis of ecological patterns. While geophagy has now been recorded in species representing all 4 platyrrhine families and a majority of genera, there is a marked tendency for it to occur in the larger-bodied Pitheciidae and

Einführung in die Platyrrhini (Neuweltaffen)

2003
Die Platyrrhini sind eine vermutlich etwa 30 Mio. Jahre alte Gruppe. Sie haben sich in Sudamerika in Abwesenheit von anderen Primaten (inklusive Strepsirrhini) entwickelt. Die Platyrrhini haben einige Formen hervorgebracht, die Gemeinsamkeiten mit den Strepsirrhini aufweisen, andere zeigen Ahnlichkeiten mit den Hominoidea, und manche haben keine nahen ...

Phylogenetic Relationships of the Platyrrhini

1980
The major problem addressed in this volume concerns the origin of the New World monkeys. This problem is sometimes simplified to the question of whether they came from North America or from Africa. However, the biological problem is actually more complex and can be treated as four separate hypotheses: (1) descent of platyrrhines from an omomyid ...
