Reproductive characteristics of wild Sanje mangabeys (Cercocebus sanjei).

摘要: An accurate description of reproductive characteristics and ovarian endocrinology is necessary to address questions about the strategies life history a species for meaningful, cross analyses. Here we used analysis fecal estradiol (fE) behavioral observations determine first time wild group (N = 18 adult 3 adolescent females) Sanje mangabeys (Cercocebus sanjei). The study was conducted in Udzungwa Mountains National Park, Tanzania, from October 2008 through September 2010. Average cycle length (±SD) 29.3 ± 3.2 days adults 51.4 ± 5.5 adolescents. Menses appeared within 5.1 ± 2.1 4.8 ± 0.3 adolescents after end maximum tumescence, lasted 6.7 ± 3.1 10.3 ± 5.0 days, respectively. Infant death tended reduce number cycles conception (4.3 ± 1.5 surviving infant vs. 2.6 ± 1.0 death). Adolescents cycled at least 16 months without conceiving. Implantation bleeding began 17.5 ± 0.7 onset detumescence, 10.0 ± 1.4 days. Gestation averaged 171.8 ± 3.4 Postpartum amenorrhea 6.7 ± 2.3 while females whose infants had died resumed cycling 14.3 ± 5.9 interbirth interval 20.0 ± 4.3 months. These mangabey resembled those other related cercopithecines, with exception an earlier longer duration menstruation implantation bleeding. Further information on physiology needed clarify what factors may cause unusual both, their menses Am. J. Primatol. 76:1163–1174, 2014. © 2014 Wiley Periodicals, Inc.
