“…This effect is likely to be due to two interacting factors: a decrease in the average litter size born (in contrast with Tardif et al [1986], who found an increase), and an increase in the number of infants surviving from each litter. The delayed improvement occurred despite the fact that all breeding females had had considerable experience with infant siblings before being paired.…”

To test the prediction that the breeding success of captive cotton-top tamarins (Saguinus (0.) oedipus) could be improved by maintaining them in groups whose size and age-sex composition resembled those of wild groups, data were collated from 6.5 years of records from a breeding colony that otherwise had housing and husbandry procedures similar to those of other successful colonies. Group size and composition in the colony closely resembled those of wild groups, and infant survival was the highest yet reported for the species, with 69% of the 124 infants born reared by their parents to adulthood, and a mean surviving litter size of 1.5 infants. Abortion, stillbirth, and parental neglect of infants were rare. Parity had several effects on reproduction: mean litter size decreased, but percentage infant survival increased; interbirth intervals decreased in length; and seasonality in reproduction was more pronounced for the first four litters born to breeding females than for their subsequent litters, with a birth peak in the spring. Although a spacious and complex physical environment, retention of offspring in their natal families until experience of several sets of infant siblings had been obtained, and non-invasive husbandry and research techniques may all have contributed to the colony's success, it seems possible that the improvement over other colonies is due to the resemblance of group composition to those of wild tamarins.

“…Attempts to breed Callitrichidae in captivity have resulted in high fertilit accompanied by high infant mortality (&bourn et al, 1983;Kirkwood et al, 1983;Tardif et al, 1986). This suggests that along with selection for increased litter size, there is strong selection perinatall on offspring phenotype.…”

Efforts to breed Callitrichidae in captivity have resulted in high fertility accompanied by high infant mortality. This paper investigates the relationship between reproductive characteristics and survivorship in the Oak Ridge and Associated Universities (ORAU) callitrichid colony. Records of 2,834 individuals were analyzed using Cox Proportional Hazards regression to investigate factors affecting infant survivorship. Species and birth cohort were found to have a significant (P less than 0.05) effect on survivorship. Litter size also was an important factor in determining survivorship. Individuals born into singlet and twin litters had significantly (P less than 0.001) higher survivorship than triplets. Factors which affect survivorship perinatally (0-1 months of age), prior to breeding age and subsequent to the first month of life were then investigated. Litter size was a significant (P less than 0.05) factor in determining survivorship perinatally, with twins having significantly higher survivorship than both singlets and triplets. After the first month of life, litter size no longer showed a significant effect on survivorship. Records of 145 dams were analyzed using the same procedures to investigate reproductive characteristics associated with survivorship. Age at first litter showed a significant (P less than 0.01) positive relationship with dam survivorship. These results suggest various factors affect survivorship at specific temporal points during development, and also suggest selection for survivorship perinatally to be strongly associated with litter size, possibly through sibling competition and maternal effects.

“…There has been extensive study of the maternal characteristics that affect postnatal infant survival in callitrichid primates [Tardif et al, 1986;Pryce et al, 1988Pryce et al, , 1993Pryce et al, , 1995Baker & Woods, 1992;French et al, 1996]. Variables that might affect the likelihood of conception or successful gestation, and therefore the number of infants born, have received less attention, particularly in wild populations.…”

We examined the effects of several variables on the number of live births in multiparous females in a wild population of golden lion tamarins (Leontopithecus rosalia). Independent variables included the number of infants born to a female the previous breeding season, the number of infants weaned the previous breeding season, the female's age and body mass, the number of adult males and helpers in the group, and the inbreeding coefficient of the offspring. We also tested the hypothesis that trapping and chemical immobilization during pregnancy affected the number of live births. Female body mass was the only statistically significant predictor of the number of live-born infants in the current season when both first and second peaks were included. Characteristics that predicted higher numbers of infants in the first peak of a season were the number of infants born the previous season and the body mass of the female. The greater the number of infants born the previous season, the greater the number of infants born in the first peak of the current season. Factors positively correlated with the number of live births in the second peak within a season included the number of infants born the previous season, as well as the number of available helpers. Due to sample size constraints, the analysis of litters in the second peak did not include body mass of the female as a variable. Inbreeding and handling did not affect the number of live births. We found no evidence that current reproduction negatively impacts future reproduction in this species. We also found no evidence for an age-related reduction in fertility.
