Folia Primatologica, 2002 //8RDue to their small size, callitrichines are subject to predation pressure by a wide array of predators. Observed predator attacks and strong responses to less dangerous or non-dangerous stimuli support this contention [1–4]. Since twin births are the rule in callitrichines but populations do not grow drastically, a large proportion of infants and ...

Phylogenetic analysis of twinning in Callitrichinae
American Journal of Primatology, 2000 The callitrichines are known for twinning and for a communal rearing system in which all or most group members help care for the offspring. The origin of twinning has been the subject of much speculation. In this study predictions from earlier hypotheses are tested on the basis of two alternative phylogenetic trees.

Mitochondrial DNA Part A, 2014 The white-tufted-ear marmoset (Callithrix jacchus) is a New World primate that inhabits the coastal rainforests of eastern Brazil. In the present work, we report the complete mitochondrial genome sequence of white-tufted-ear marmoset for the first time.

Vertical clinging, small body size, and the evolution of feeding adaptations in the Callitrichinae
American Journal of Physical Anthropology, 1992 AbstractPrimates 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 ...

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 ...

Primates, 2015 Cruz Lima's saddle-back tamarin Saguinus fuscicollis cruzlimai Hershkovitz, 1966, was described from a painting by Eládio da Cruz Lima in his book Mammals of Amazonia, Vol. 1, Primates (1945). The painting was of four saddle-back tamarins from the upper Rio Purus, one of them distinct and the inspiration for Hershkovitz to describe it as a new ...

Zoo Biology, 1999 This study examines the temporal patterning of gum feeding in two species of sympatric tamarin monkeys, Saguinus mystax and Saguinus fuscicollis, during the diurnal activity period. The number and duration of visits to gum sources and number of gum feeding records are used as parameters to analyze the gum feeding itinerary.

Behavioral Ecology and Sociobiology, 1998 This study examines the hypothesis that sexual selection has shaped patterns of olfactory communication in wild moustached tamarins, Saguinus mystax. Do sex differences exist in frequencies and in the intensity of scent marking, in the use of different scent-marking types, and in behavioural responses to scent marks?

Primates, 2014 We analyzed 115 Saguinus leucopus, from four Colombian departments (Antioquia, Bolivar, Caldas and Tolima ), for 701 bp of the mt COII gene and at 10 microsatellite loci to estimate gene diversity levels, possible molecular subspecies and historical demographic changes in this species. This endemic Colombian species showed an elevated gene diversity in

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
