“…& LOPES FERRARI, 1989;GOLDIZEN et al, 1988;DIETZ et al, 1994;SAVAGE et al, 1996) cannot be tested in this study due to the regular food supply of these monkeys in captivity. Indeed, we cannot explain our results with basis in reproductive synchronism among females as found as occurring for Leontopithecus rosalia (FRENCH & STRIBLEY, 1987) since reproductive physiology studies have never reported this condition to occur for marmosets. Therefore, the existence of significant differences in PPI length as a function of time (month) of pairing, and in IBI length as a function of date of the previous litter birth in our results, appears to represent the way the animals in our colony adjust the births to a specific period of the year.…”

ABSTRACT. We analyzed data on captive-born and wild-caught females housed under natural conditions in a colony located in northeastern Brazil. No differences in reproductive performance were found between captive-born and wild-caught females. Twins were the most frequent litter size, followed by triplets and singletons. No parity effect was observed, with similar infant survival for nulliparous and multiparous females. No significant departures in sex ratio were detected for births and mortality of the male and female infants. The age of the females at the time of pairing showed a negative correlation with pairing-parturition length, but did not affect infant survival. The prolongation in pairing-parturition interval (PPI) and interbirth interval (IBI) was related to birth seasonality. The births were clustered in the second half of the dry season and the beginning of the wet season (November-March), and the time of pairing and the time of infant birth influenced the PPI and IBI, respectively. The use of outdoor cages, which allowed the animals to be aware of the seasonal variations in photo-period and rainfall seems to be sufficient to time the reproductive activity, even when the animals are maintained on a constant food supply.

“…Due to intense reproductive competition in the species, the dominance relationship among females has been very well studied. However, documentation about escape from inhibition by subordinate calli-thrichid females in laboratory groups (among mothers and daughters or among unrelated females) has shown that reproductive inhibition is not as stringent as thought (7)(8)(9)(10)(11). The escape from inhibition by subordinate females (daughters) was also recorded in a monogamous wild group of common marmosets (12).…”

In captive common marmoset groups, the reproductive inhibition observed in subordinate female seems to be a result of olfactory, visual and behavioral cues from the dominant female. However, few studies have examined the relationship among adult males living in the same social group. These studies have shown that reproductive failure among peer males seems to be based on hormonal and behavioral mechanisms. New insights on sexual strategies in primates have been shown using fecal steroids, but so far no information is available for common marmoset males. In the present study, we evaluated the influence of light-dark cycle, age and reproductive condition on the profile of fecal androgens in males living in the same family group. Feces were collected from six fathers and six sons for androgen determination during the light phase of the 24-h cycle for eight days randomly distributed over a 4-week period. Androgen levels were determined by enzyme immunoassay technique. Adult sons showed higher androgen levels (166.97 ± 22.95 ng/g) than fathers (80.69 ± 44.38 ng/g) and juveniles (49.06 ± 23.15 ng/g; P < 0.05). No diurnal variation (P > 0.05) in fecal androgen profile was observed in adults or juveniles. No indication of androgen-mediated social competition between fathers and adult sons was demonstrable. These results provide basic information on fecal androgen profile useful to investigate the socioendocrinology of free-ranging common marmoset males and verify that, in contrast to daughters, the reproductive suppression of sons is not based on physiological inhibition of their gonads.

“…Laboratory studies have demonstrated behavioral and physiological suppression of fertility in subordinate female marmosets and tamarins, but the mechanisms appear to vary across species [for examples: Callithrix jacchus, Abbott, 1984; Saguinus fuscicollis, Epple & Katz, 1984; Saguinus oedipus, French et al, 1984; Leontopithecus rosalia, French & Stribley, 1987; Saguinus oedipus, Savage et al, 19881. Few studies have addressed any role that male Callitrichids may have on the enhancement or stimulation of reproductive function in females [see Tardif, 1984;Ziegler et al, 1987b;Widowski et al, 19901.…”

“…The onset of ovulatory cycling in pubertal female cotton-top tamarins (Saguinus oedipus) appears to be controlled by an interaction among the suppressive effects of the breeding female and/or other family members and the stimulatory effects of pairing with an unfamiliar male [French et al, 1984;Ziegler et al, 1987b;Widowski et al, 19901. Reproductive hormones remained low and acyclic and scent marking and sexual behavior were rarely observed as long as females lived in their natal groups, but both hormones and behavior changed dramatically after females were removed from their family and paired with an unfamiliar male [French et al, 1984;Savage et al, 1988;Widowski et al, 19901.…”

Prior studies have shown that female cotton-top tamarins usually do not ovulate while living with natal groups, and most females do not ovulate until they are paired with an unfamiliar adult male. To examine the role of unfamiliar adult males on stimulating ovarian function, four cotton-top females were studied during three conditions: females living with their natal group for six weeks, living alone but exposed to a single unfamiliar adult male located 15 cm away from the female's cage for four weeks, and living with an unfamiliar adult male for six weeks. Behavior and urinary hormonal concentrations were measured during the three conditions. Exposure to the male consisted of visual, auditory, and airborne olfactory contact. First ovulation occurred during exposure to the unfamiliar male in three of the four females indicating that direct physical or sexual contact with the male is not required for onset of ovarian cycling. The fourth female did not ovulate even during six weeks of direct contact with the unfamiliar adult male. In addition, four parous females in either family groups (3) or singly caged (1) were examined for ovarian function 4-6 months after the death or removal of their mates. All females continued to cycle in the absence of the male indicating that the male was not needed to continue ovarian cycling. In fact, two of the females were pregnant at the time their males died and both delivered normal infants and resumed cycling. The results of this study indicate that an unfamiliar adult male may facilitate the onset of ovarian cycling without being in direct contact with the female and visual, auditory, or airborne olfactory cues may be involved. Once repeated ovarian cycling occurs the male is not required to maintain ovarian function.
