Sexual conflict and partner manipulation in simultaneous hermaphrodites:Dr. Barry R Sinervo and Brooke L W MillerMating often appears to be a friendly encounter, however, in actuality, conflicts of interest often exist between mating partners. Males seek to prevent females from mating with additional partners to prevent sperm competition, whereas females often seek additional mating partners to reduce the cost of mating with a bad sire. These "sexual conflicts" can lead to the evolution of behaviors that males use to manipulate the mating behavior of the female ("partner manipulation tactics"). Simultaneous hermaphrodites are animals that are both male and female at the same time. They are excellent systems to study sexual conflict due to their unique biology, yet are relatively unstudied. This project examines sexual conflict, sperm competition and the evolution of partner manipulation strategies in the simultaneously hermaphroditic Banana slug, Ariolimax dolicophallus. These slugs exhibit a highly unusual mating behavior of penis chewing after mating, which is explored as an evolved response to sperm competition.Sinervo and Miller have a long standing interests in science outreach, and this project has been very popular among non-science audiences. Also, because this project is labor intensive, it allows them to work closely with a team of undergraduate students (mostly women) and mentor them on the basics of scientific research. Undergraduates learn a variety of broadly applicable field and molecular laboratory research techniques that they can use in a variety of scientific fields.

两性人同时交配中的性冲突和伴侣操纵：巴里·R·辛纳沃博士和布鲁克·L W·米勒交配通常看起来是一次友好的邂逅，但实际上，交配伙伴之间往往存在利益冲突。雄性试图阻止雌性与更多的配偶交配，以防止精子竞争，而雌性通常寻求更多的交配伙伴，以降低与糟糕的雄性交配的成本。这些“性冲突”可能导致雄性用来操纵雌性交配行为的行为的演变(“伴侣操纵策略”)。同时的两性动物是指同时是雄性和雌性的动物。由于它们独特的生物学特性，它们是研究性冲突的优秀系统，但相对来说还没有被研究过。这个项目研究了同时两性的香蕉弹头，Ariolimax dolicopallus的性冲突，精子竞争和伴侣操纵策略的演变。这些鼻涕虫表现出一种非常不寻常的交配行为，即交配后咀嚼阴茎，这被认为是对精子竞争的进化反应。西内沃和米勒长期以来一直对科学推广感兴趣，这个项目在非科学观众中非常受欢迎。此外，由于这个项目是劳动密集型的，它允许他们与一组本科生(主要是女性)密切合作，并在科学研究的基础上指导他们。本科生学习各种广泛适用的领域和分子实验室研究技术，他们可以在各种科学领域使用这些技术。
