对生活在4个无母亲家庭的12只性成熟雌性棉铃虫(Saguinus Oedipus)的生育状况和气味标记行为的表现，研究了母亲S的缺席对其生育状况和气味标记行为表达的影响。平均每周收集5次行为数据和尿样，并用放射免疫法直接测定雌酮-葡萄糖醛酸苷(E1G)水平，以确定雌性是否表现出卵巢周期。在被调查的12名女性中，只有每一组中的优势女性表现出规律的E1G周期。相比之下，下属姐妹的荷尔蒙水平较低，且为非周期激素。除了E1G的模式和水平的差异外，香腺形态和气味标记率在雌性之间也不同：优势的、骑自行车的雌性有精致的腺体，气味标记率明显高于下级。这些结果表明，母亲(配种雌性)的存在是调节棉罗兰子代卵巢功能的一个重要因素。研究结果还表明，优势地位是每个雌性S随后生理繁殖能力的重要决定因素，只有优势地位的雌性才能获得完全的生育能力，并可能抑制其下属姐妹的排卵活动。气味标记行为似乎参与了这种性内繁殖竞争现象的调节。
The effect of the mother''s absence on the fertility status and expression of scent marking behavior was examined in 12 sexually mature female cotton-top tamarins (Saguinus oedipus) living in four motherless families. Behavioral data and urine samples were collected on an average of five times per week and levels of estrone-glucuronide (E1G) were quantified directly by radioimmunoassay to establish whether the females showed ovarian cyclicity. Of the 12 females investigated only the dominant female in each motherless group exhibited regular E1G cycles. By contrast, low and acyclic hormonal profiles were found for subordinate sisters. In addition to differences in the patterns and levels of E1G, scent gland morphology and rates of scent marking differed between females: dominant, cycling females had elaborate glands and significantly higher rates of scent marking than subordinates. These results indicate that the presence of the mother (breeding female) is one important factor regulating ovarian function in cotton-up tamarin daughters. The findings also show that dominance status is a vital determinant of each female''s subsequent physiological reproductive competence, with only the dominant female obtaining complete fertility and probably inhibiting ovulatory activity in her subordinate sisters. Scent marking behavior seems to be involved in the regulation of this phenomenon of intrasexual reproduction competition.
