Dissertation Research: Coercion and Reconciliation in a Socially Monogamous SpeciesRobert G. Jaeger, Ph. D.Ethan D. Prosen, M.S. This research project examines the effects of aggression on socially monogamous behavior using the red-backed salamander (Plethodon cinereus) as a model organism. In laboratory studies, some males and females of this territorial species have shown a preference for associating with their partner relative to other individuals of the opposite sex (i.e., are socially monogamous). This preference is unknown in other amphibians. Preliminary evidence implies that both sexes direct aggressive behavior towards partners that associate with individuals of the opposite sex (i.e., are "fickle"). This increased aggression, or "sexual coercion", may be what drives some individuals toward social monogamy. Primate studies have shown that reconciliation, or making-up behavior, reduces the negative effects that result from aggression between individuals that often interact. There has been a call for research exploring the possibility of reconciliation in animals outside of the primates. Red-backed salamanders exhibit two of the three minimum requirements for reconciliation: long-term memory and individual recognition. Therefore, it is hypothesized that partners will display reconciliation behavior after aggression following a fickle event. These experiments look at how intimidation shapes the social behavior of red-backed salamanders. This research tests the general hypothesis that aggression can maintain socially monogamous partnerships. Parental investment theory predicts social monogamy to be rare, especially when males provide no direct resources to offspring. Because red-baked salamander males provide no direct resources to offspring, this species provides an ideal situation for the exploration of the maintenance of social monogamy. In addition, finding evidence of reconciliation in a lower vertebrate such as salamanders would open up a field dominated by primate studies.

论文研究：社会上一夫一妻制物种的胁迫与和解。Jaeger，Ph. D.Ethan D. Prosen，M.S.本研究以红背蝾螈（Plethodon cinereus）为模式生物，探讨攻击行为对社会一夫一妻制行为的影响。 在实验室研究中，这种领地物种的一些雄性和雌性表现出与其他异性个体相比与伴侣交往的偏好（即，一夫一妻制）。 这种偏好在其他两栖动物中是未知的。 初步证据表明，两性都会对与异性个体相关的伴侣采取攻击性行为（即，是“善变的”）。 这种增加的侵略性，或“性胁迫”，可能是驱使一些人走向社会一夫一妻制的原因。灵长类动物的研究表明，和解，或弥补行为，减少了经常互动的个体之间的侵略所造成的负面影响。 有人呼吁进行研究，探索灵长类动物以外的动物和解的可能性。 红背蝾螈表现出和解的三个最低要求中的两个：长期记忆和个体识别。 因此，它是假设，合作伙伴将显示和解行为后，侵略后变化无常的事件。这些实验着眼于恐吓如何塑造红背蝾螈的社会行为。 这项研究测试了一般假设，即侵略性可以维持社会一夫一妻制的伙伴关系。 父母投资理论预测社会一夫一妻制是罕见的，特别是当男性不提供直接的资源给后代。 由于红烤蝾螈雄性不提供直接的资源给后代，这个物种为探索社会一夫一妻制的维持提供了理想的环境。 此外，在蝾螈等低等脊椎动物中找到和解的证据将开辟一个由灵长类动物研究主导的领域。
