A New Subspecies of Saguinus fuscicollis (Primates, Callitrichidae)

International Journal of Primatology, 2009
Saddleback tamarins (Saguinus fuscicollis, S. melanoleucus, and S. tripartitus) occur in the upper Amazon, west of the rios Madeira and Mamore–Guapore to the Andes. They currently comprise 13 species and subspecies in Bolivia, Brazil, Colombia, Ecuador, and Peru.

Hematologic iron analyte values as an indicator of hepatic hemosiderosis in callitrichidae

American Journal of Primatology, 2008
AbstractHepatic hemosiderosis is one of the most common postmortem findings in captive callitrichid species. Noninvasive evaluation of hematologic iron analytes has been used to diagnose hepatic iron storage disease in humans, lemurs, and bats. This study evaluated the relationship between hematologic iron analyte values (iron, ferritin, total iron ...

Stereology of the myocardium inLeontopithecus(Lesson, 1840) callitrichidae – primates

Journal of Medical Primatology, 2003
Abstract:Rare morphological features of theLeontopithecuscardiovascular system have been reported in the literature. The samples analyzed in this study came from 33 specimens ofLeontopithecusfrom the collection of the Center of Primatology of Rio de Janeiro‐FEEMA (CPRJ‐FEEMA). Morphometry and stereological data were obtained from all animals.

Anomalous Pigmentation in Invasive and Native Marmosets, Callithrix jacchus, Callithrix penicillata (Primates, Callitrichidae), and Their Hybrids in Brazil

Folia primatologica, 2019
Leucism is the lack or reduction in pigmentation in the most or parts of the body, but not in the eyes and body extremities. It is extremely rare in primates and has never been reported for Callithrix, a genus endemic to Brazil.

Ecological differentiation in the Callitrichidae

1993
Abstract The most obvious and absolute difference between callitrichids and all other anthropoid primates is their small size, a characteristic which, along with other diagnostic features of their biology, is intimately related to an evolutionary process of specialization for the efficient colonization of marginal and disturbed forest ...

The Vocal Identity of the Callithrix Species (Primates, Callitrichidae)

2009
We have recorded long calls of free ranging groups of six Callithrix species, looking for species-specific parameters in the physical structure of the vocalizations. This comparative study is the first time a behavioral character (vocalization) has been incorporated in a study on Callithrix taxonomy.

The Banded Karyotype of Saguinus midas tamarin Link, 1795 (Callitrichidae, Primates)

Folia Primatologica, 1977
The karyotype of Saguinus midas tamarin (2n = 46) is presented. By G-banding all individual chromosome pairs are easily identifiable.

Reproductive performance of three species of Callitrichidae.

Laboratory animal science, 1984
The reproductive performance of three species of Callitrichidae housed under identical conditions, including relatively spacious caging and visual screening, was compared. The three species were Callithrix jacchus, Saguinus fuscicollis, and Saguinus oedipus.

Ultrasonographic aspects of the Leontopithecus gestation (Lesson, 1840—Callitrichidae, Primates)

Journal of Medical Primatology, 2017
AbstractBackgroundThere is a concern about conservation of endangered species today. Among this species, the Leontopithecus (Lesson, 1840) is outstanding. Its population has been whirling reduced. So far the reproductive physiology of Leontopithecus has few studies, it is fundamental requisite to preserve this species.

Craniometric sexual dimorphism inLeontopithecus Lesson, 1840 (Callitrichidae, Primates)

Primates, 1997
Lion tamarins are among the World's most critically endangered primates. Many studies have been produced under guidance of the International Management Committees for the preservation and management of these tamarins. Primates present morphological sexual differences in a wide range of characteristics, including cranial morphology.
