“…In another Trachypithecus species, Gibson and Chu [1992] estimate 6.5-7.0 months (equivalent to 198-213 days) for captive Francois leaf monkeys. For captive Rhinopithecus species gestation lengths of 189-208 days were determined [Hama et al, 1997;He et al, 2001;Ji et al, 1998;Qi, 1986;Ren et al, 2003], for Douc langurs 210 days [Lippold, 1981], for wild Hanuman langurs 210 days [Borries et al, 2001] and for provisioned ones 200 days [Sommer et al, 1992]. In all these species females are about 21 kg heavier than in silvered leaf monkeys [Smith & Jungers, 1997] and as expected, gestation periods were slightly longer.…”

Within phylogenetic limits reproductive characteristics of a given species may vary between populations in response to ecological and social factors. For instance, in environments where high quality nutrition is readily available, the onset and speed of reproduction are often accelerated. Other influencing factors might be maternal experience or the sex of the infant. Here we present data on reproductive characteristics for the silvered leaf monkey (Trachypithecus cristatus), a medium-sized Asian colobine housed at the Wildlife Conservation Society's Bronx Zoo as a one-male group. To place the species into an appropriate phylogenetic context, we limited our comparison to other colobine species. Demographic data span 21.4 years (October 1985 to March 2007) and derive from 30 adult females (128.0 female years). Detailed behavioral data stem from a 2.2 years study (November 2002 to January 2005; 734 days, 4,225 hr). As in other Asian colobines, receptive periods were short (mean=4.3 days, n=68). This is expected for one-male groups where receptivity likely indicates, rather than conceals, ovulation. Gestation length was estimated based on a change in the pattern of sexual behavior (mean=194.6 days, n=7). It fell within the range reported for the taxon. Births occurred year round, at an early age (mean=2.9 years, n=8), at short intervals (mean=14.9 months, n=59) in combination with a short lactation (mean 12.1 months, n=9) likely due to the nearly unlimited availability of nutrition in this zoo setting. Primiparous females tended to have a longer first interbirth interval but infant survival rates were similar to multipara possibly due to the absence of predators. Maternal investment was independent of the infant's sex and birth sex ratio was even. Our results emphasize that when interpreted with caution, zoo populations yield realistic reproductive characteristics that can help fill the gap in our knowledge about colobine life history.

“…The study animals were one adult male and four adult female R. bieti housed at the Kunming Institute of Zoology (KIZ) [Ji et al, 1998], and one adult male and three adult females of the same species kept at the Kunming Zoo (KZ). All of the animals had been captured from a group in Wenxi County (27127 0 N, 99111 0 E) in northwest Yunnan.…”

“…The social systems of R. bieti at Wuyapaya are composed of several multi-female, one-male units, and an all-male unit [Kirkpatrick et al, 1998]. Although the evidence is circumstantial, Kirkpatrick et al [1998] concluded that the birth season of the Wuyapuya group of R. bieti starts in March and ends in April, with August and September being the height of the breeding season [Kirkpatrick et al, 1998], and with a gestation period of 6.5-7 months [Ji et al, 1998]. The ratio of infants to adult females (1.0:2.3) at the end of the birth season [Kirkpatrick et al, 1998] suggests that the interbirth interval (IBI) is approximately 2 yr.…”

This study, which is based on 10 years of birth records, shows that black-and-white snub-nosed monkeys (Rhinopithecus bieti) in captivity display marked birth seasonality. The birth season starts in December and ends in June, with a peak from March to May, and a median birth date of April 10. More male infants than female ones are born in captivity. More males were born at the Kunming Institute of Zoology (KIZ) than at the Kunming Zoo (KZ). Of 17 interbirth intervals (IBIs), 29% were from females that had lost an infant at <1 year of age or experienced stillbirth, and 71% were from females whose infant survived more than 1 year. The mean IBI for the former group (428+/-SD 87 days) was significantly shorter than that for the latter group (706+/-71 days), in agreement with reports of other Colobine species. Infant mortality was lower in captivity than in the field, which may reflect the relatively stable food availability and climate in captivity compared to the harsh conditions in the wild.

“…Some studies have addressed the reproductive behavior in this genus [Qi, 1989;Clarke, 1991;Ren et al, 1995;Ji et al, 1998], but no work has been carried out on possible seasonality of matings and births. Meanwhile, reproductive seasonality is a very important aspect in the life history of animals, as they must be able to adjust to, and even anticipate, the changes taking place around them [Follett, 1984].…”
