在许多灵长类动物中，雌性的性吸引力受到行为线索和非行为线索的影响（即，视觉形态学或化学信号）。这两种线索通常与卵巢周期和女性荷尔蒙状态有关。雌性簇绒卷尾猴（Cebus apella）缺乏任何与卵巢周期有关的外部形态变化，并且从未报道过气味标记行为的证据。此外，雄性卷尾猴并不经常检查雌性卷尾猴的身体或尿液。相反，雌性卷尾猴在性引诱雄性卷尾猴方面非常活跃，它们对雄性卷尾猴的求爱涉及到丰富的行为。本研究定义了雌性卷尾猴的感知性，并探讨了感知性与雌性生殖状态的关系。测量来自四只圈养雌性的尿液和粪便样品中的卵巢激素，以便（a）评估它们用于监测雌性卵巢功能的可靠性和（B）提供关于组成周期阶段，特别是排卵期的时间的信息。尿液和粪便中的孕酮代谢物的测量提供了最好的：卵巢周期性和围排卵期时间的指标。通过对行为数据集的多变量分析，我们区分了四种行为（眉毛提高与发声，触摸和运行，nuzzling和头部竖起），这表明了显着的周期性（21.3天），匹配的尿孕酮（21.9天）。数据显示，每个生殖行为周期为2.7 ± 0.8天，尿孕酮水平的确定黄体期的日期明显向该周期结束时偏移。此外，观察到的射精总是发生在感受期内。结果清楚地表明，雌性行为是围排卵期的一个指标，可以提高雌性吸引力。(C)北京：科学出版社.
In many primates species, female sexual attractivity is influenced by behavioral cues as well as by nonbehavioral cues (i.e., visual-morphological or chemical signals). Both kinds of cues are usually related to the ovarian cycle and female hormonal state. Female tufted capuchins (Cebus apella) lack any external morphological change in relation to the ovarian cycle and evidence of scent-marking behavior has never been reported. In addition, tufted capuchin males do not routinely investigate the female's body or urine. Instead, capuchin females are extremely active in sexually soliciting the male(s) and their courtship toward them involves a rich behavioral repertoire. In the present study we defined female tufted capuchin proceptivity and investigated its relationship with female reproductive state. ovarian hormones were measured in urine and fecal samples from four captive females in order to (a) assess their reliability for monitoring female ovarian function and (b) provide information on the timing of the component cycle phases and in particular the periovulatory phase. Measurements of urinary and fecal progestin metabolites provided the best: indicator of ovarian cyclicity and for timing of the periovulatory phase. Through a multivariate analysis of the behavioral data set we distinguished four behaviors (eyebrow raising with vocalization, touching-and-running, nuzzling and head cocking) which showed a marked cyclicity (21.3 days) that matched that of urinary progesterone (21.9 days). Data showed that each period of proceptive behaviors was 2.7 +/- 0.8 days long and the day of a defined luteal phase vise in urinary progesterone levels was markedly shifted toward the end of this period. Furthermore, the ejaculations observed always occurred within proceptive periods. The results clearly indicate that female behavior is a goad indicator of the periovulatory phase and can enhance female attractivity. (C) 1999 Academic Press.
