Electrophoretic Polymorphisms and Their Taxonomic Implications in Callitrichini (Primates, Platyrrhini)

Biochemical Genetics, 1998
Five hundred forty-three blood samples from 15 populations of the four genera of callitrichin primates were studied electrophoretically. Polymorphism and genetic distances were estimated for 20 loci, 13 of which were polymorphic. The lion tamarin (Leontopithecus) studied here exhibited the least variability for these loci, while the monospecific ...

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.

AVPR1b variation and the emergence of adaptive phenotypes in Platyrrhini primates

American Journal of Primatology, 2019
AbstractPlatyrrhini (New World monkeys, NWm) are a group of primates characterized by behavioral and reproductive traits that are otherwise uncommon among primates, including social monogamy, direct paternal care, and twin births. As a consequence, the study of Platyrrhine primates is an invaluable tool for the discovery of the genetic repertoire ...

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

Comparative karyology and evolution of the Amazonian Callithrix (Platyrrhini, Primates)

Chromosoma, 1996
Chromosomal studies in three species of Amazonian Callithrix (2n=44) and data in the literature show that this group is karyomonotypic. Moreover, it is characterized by the presence of abundant heterochromatic regions, unlike the situation in congeneric forms of Callithrix of the Atlantic coast with 2n=46, and by the presence of a highly repetitive ...

The Y Chromosome of the Atelidae Family (Platyrrhini): Study by Chromosome Microdissection

Cytogenetic and Genome Research, 2009
In order to study the intergeneric variability of the Y chromosome, we describe the hybridization of the Y chromosome of <i>Brachyteles</i><i>arachnoides</i>, obtained by microdissection, to metaphases of <i>Ateles</i><i>belzebuth</i><i>marginatus</i>, <i>Lagothrix</i><i> ...

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 ...

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.

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.

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 ...
