Renal papillary adenoma in a cotton-topped tamarin (Saguinus oedipus)

Food-sharing in cotton-top tamarins (Saguinus oedipus).

Food-sharing behaviour was observed in 9 captive families of cotton-top tamarins (range 4-14 individuals per group), during meals of fresh fruit. Food was transferred to infants by their parents and older sibs in response to begging, and was also offered to them without prior solicitation. Older, mature, reproductively suppressed individuals shared more than young immature monkeys. Infants in l...

Body weight increase in expectant males and helpers of cotton-top tamarin (Saguinus oedipus): a symptom of the Couvade syndrome?

In the cooperative breeding system of cotton-top tamarin (TCB; Saguinus oedipus) <> males gain weight during the last months of pregnancy of their partners as a way to cope with energy costs of reproduction. This phenomenon was described only in humans as a symptom of <>. As after infants' birth, TCB male and female helpers lose weight, the same as fathers do, it mi...

Major-histocompatibility-complex DRB genes of a New-World monkey, the cottontop tamarin (Saguinus oedipus).

The DRB region of the human and great-ape major histocompatibility complex displays not only gene but also haplotype polymorphism. The number of genes in the human DRB region can vary from one to four, and even greater variability exists among the DRB haplotypes of chimpanzees, gorillas, and orangutans. Accumulating evidence indicates that, like gene polymorphism, part of the haplotype polymorp...

Activity Profiles and Hormone Metabolites in a Captive Group of Eight Cotton - Top Tamarins , Saguinus oedipus

A two-choice preference assessment with five cotton-top tamarins (Saguinus oedipus).

A study selected 5 cotton-top tamarins (Saguinus oedipus) located at the Frank Buck Zoo in Gainesville, Texas, for a food preference assessment. The study used a paired-choice procedure across 7 different food items for all 5 tamarins. Preferences for the food items across all the tamarins varied, although general trends were noted as well. This article discusses the benefits of using paired-ch...
