AbstractA typical monkey of the subfamily Callitrichinae has two or more cell lineages occupying its tissues: one from "itself," and one from its co-twin(s). Chimerism originates in utero when the twin placentae fuse, vascular anastomoses form between them, and cells are exchanged between conceptuses through their shared circulation.

Molecular Phylogenetics and Evolution, 2018 Marmosets and tamarins (Cebidae, Callitrichinae) constitute the most species-rich subfamily of New World monkeys and one of the most diverse phenotypically. Despite the profusion of molecular phylogenies of the group, the evolution of phenotypic characters under the rapidly-emerging consensual phylogeny of the subfamily has been little studied ...

Vertical clinging, small body size, and the evolution of feeding adaptations in the Callitrichinae
American Journal of Physical Anthropology, 1992AbstractPrimates of the subfamily Callitrichinae (Callimico, Callithrix, Leontopithecus, and Saguinus) are small‐bodied New World monkeys (105–700 g) possessing clawlike nails on all manual and pedal digits excluding the hallux. Specialized nails in these genera serve a critical function in feeding by enabling tamarins and marmosets to cling to trunks ...

Dental scaling in the callitrichinae
International Journal of Primatology, 1993Callitrichines share several morphological features that appear to be derived among anthropoid primates. One view maintains that some of them are the consequence of a rapid reduction in body size in the common ancestor of callitrichines. This hypothesis predicts that callitrichines should have relatively large teeth for their body size in comparison to

American Journal of Primatology, 1999
The phylogenetic relationships of callitrichine primates have been determined by DNA sequence analyses of exons 1, 2, and 3 of the beta2-microglobulin gene. Parsimony, distance, and maximum likelihood analyses of ca. 900 base pairs of 21 taxa, representing all callitrichine genera, indicated that Saguinus was the most basal offshoot. Within Saguinus, S.

Cladistics, 2015
AbstractThe marmosets, tribe Callitrichini, are the most speciose clade in the subfamily Callitrichinae, containing 21 species. However, there is no consensus among molecular and morphological systematists as to how many genera should be recognized for the group.

Revalidation of Saguinus ursula Hoffmannsegg (Primates: Cebidae: Callitrichinae)
Zootaxa, 2013In this study, we review the taxonomy of Saguinus niger (É. Geoffroy) and revalidate Saguinus ursula Hoffmannsegg as a distinct species. The revalidation is based on pelage coloration, and the pattern of morphological divergence is corroborated by molecular data. Samples from the east bank of the Tocantins River (S.

Mitochondrial DNA Part A, 2015
The Wied's black-tufted-ear marmoset, Callithrix kuhlii, is a New World monkey that lives in tropical and subtropical forests of eastern Brazil. In this study, the mitochondrial genome sequence of this species is determined, which is found to be 16 500 bp in length and consists of 22 transfer RNA genes, 13 protein-coding genes, 2 ribosomal RNA genes ...

Folia Primatologica, 1984
A survey of craniodental variability of the three allopatric populations of Leontopithecus reveals that they are morphologically heterogeneous and individually distinctive, with a nonclinal distribution of characters and pattern similarities. These observations correspond with their better known, starkly different coat coloration, and imply important ...

Effects of forest structure components on the occurence, group size and density of groups of bare-face tamarin (Saguinus bicolor - primates: Callitrichinae) in Central Amazonia [PDF]
Acta Amazonica, 2006 This study analyzed the influence of forest structural components on the occurence, size and density of groups of Bare-face Tamarin (Saguinus bicolor) - the most threatened species in the Amazon - and produced the first map of distribution of groups in large-scale spatial within the area of continuous forest.
