Social monogamy has long been of interest to anthropologists, primarily because it is a rare social system in mammals, but appears to be more prevalent among primates, and is especially common in humans. Although pair-bonds are considered an important component of human mating and parenting strategies, we understand relatively little about the dynamics of male-female relationships. Reviews of social monogamy across a wide range of taxa, including human societies, have demonstrated significant variation in male-female relationships, which has contributed to a longstanding debate regarding the functional significance of pair-bonds.This project by doctoral student Amy Porter (University of California, Davis), supervised by Dr. Lynne Isbell, investigates comparative aspects of pair-bonding and territorial behavior in two socially monogamous primates, red titi monkeys (Callicebus discolor) and equatorial saki monkeys (Pithecia aequatorialis), in which males and females differ in their degrees of parental care and contributions to territorial behavior. This research will test the hypotheses that 1) differences in direct paternal care and the potential costs of cuckoldry and/or abandonment are related to differences in pair-mate relationships and male-female mate guarding strategies; and 2) vocal communication in titis and sakis is a component of their mate guarding strategies. The hypotheses are tested using systematically collected behavioral data and vocal playback experiments.The fine-scale analysis of social interactions between pair-mates will contribute substantially to broader theoretical issues in evolutionary biology, especially those that relate to mating and parenting strategies. These data are particularly relevant to understanding our own species, where there is substantial variation in male-female relationships and the patterning of gender roles, both within and between populations. This research also will contribute to the field of ornithology by providing comparative data on how two socially monogamous mammals use vocal communication in mate-guarding and territoriality, two common behaviors in birds.

社会一夫一妻制长期以来一直受到人类学家的关注，主要是因为它在哺乳动物中是一种罕见的社会制度，但似乎在灵长类动物中更为普遍，在人类中尤其常见。虽然配对关系被认为是人类交配和养育策略的重要组成部分，但我们对男女关系的动态了解相对较少。对包括人类社会在内的广泛分类群中的社会一夫一妻制的回顾表明，男女关系存在显著差异，这导致了关于配对债券功能意义的长期争论。（加州大学戴维斯分校），由Lynne Isbell博士监督，研究了两种社会性一夫一妻制灵长类动物红提提猴的配对和领土行为的比较方面（Callicebus discolor）和赤道萨基猴（Pithariaequatorialis），其中男性和女性在父母的照顾程度和领土行为的贡献不同。本研究将检验以下假设：1）直接父亲照顾的差异和戴绿帽子和/或遗弃的潜在成本与配偶关系和男女配偶保护策略的差异有关; 2）Titis和Sakis的声音交流是其配偶保护策略的一个组成部分。通过系统收集的行为数据和声音回放实验对假设进行了检验，对配偶之间社会互动的精细分析将大大有助于进化生物学中更广泛的理论问题，特别是那些与交配和养育策略有关的问题。这些数据与了解我们自己的物种特别相关，其中男女关系和性别角色模式存在很大差异，无论是在种群内部还是种群之间。这项研究也将有助于鸟类学领域提供关于两种社会性一夫一妻制哺乳动物如何在配偶保护和领土方面使用声音交流的比较数据，这是鸟类中的两种常见行为。
