Revalidation of Saguinus ursula Hoffmannsegg (Primates: Cebidae: Callitrichinae)

Zootaxa, 2013
In 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.

SRY Evolution in Cebidae (Platyrrhini: Primates)

Journal of Molecular Evolution, 2002
Sex determination in mammals is dependent on the presence of SRY, which codes for a protein with a DNA binding motif (the HMG-box domain). Here we analyze the evolution of SRY among seven genera of New World monkeys belonging to the family Cebidae. Estimates of the number of synonymous and nonsynonymous substitutions indicated the absence of positive ...

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.

Aging Cebidae

2008
New World monkeys have been used extensively as biomedical models for human diseases, yet little is known about aging in these animals. Life spans in cebids vary, with most species living to approximately 20-30 years of age. Capuchins may be an exception, possibly living as long as 40-50 years.

Preliminary Observations of Cebus nigrivittatus (Primates: Cebidae) on the Venezuelan Llanos

Folia Primatologica, 1973
Brief observations were made of Cebus nigrivittatus in a dry forest on the Venezuelan llanos. Data were obtained on the social behavior of one troop of 33 individuals, which included 4 adult males and 8 adult females. Eleven vocal and seven visual displays were noted and the associations between them were analyzed.

Intestinal disaccharidase activity of non-human primates—II. Lorisidae, hapalidae, cebidae

Comparative Biochemistry and Physiology Part A: Physiology, 1973
Abstract 1. 1. Disaccharidase activities of the small intestine of non-human primates (Lorisidae, Hapalidae and Cebidae families) and of humans were assayed. 2. 2. In the non-human primates, disaccharidase concentrations usually peaked in the jejunum. The black and red tamarins had the highest concentrations of palatinase, sucrase and maltase;

Intestinal disaccharidase activity of non-human primates—I. Tupaiidae, Cebidae and Cercopithecidae

Comparative Biochemistry and Physiology Part A: Physiology, 1972
Abstract 1. 1. Disaccharidase activities in general were the highest in the jejunum of the Tupaiidae, Cebidae and Cercopithecidae studied. 2. 2. In the proximal jejunum of the Cebidae and Cercopithecidae, the disaccharidases increased in activity in the following order: cellobiase, lactase, palatinase, trehalase, sucrase and maltase.
