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.

性冲突和伴侣的操纵同时雌雄同体：博士。 Barry R Sinervo和Brooke L W Millermating通常是一次友好的遇到，但是实际上，交配伙伴之间经常存在利益冲突。 男性寻求防止女性与其他伴侣交配以防止精子竞争，而女性经常寻求其他交配伴侣来降低与父亲的交配成本。 这些“性冲突”可能导致男性用来操纵女性交配行为的行为的演变（“伴侣操纵策略”）。 同时雌雄同体是同时都是雄性和女性的动物。 由于其独特的生物学，它们是研究性冲突的出色系统，但相对未被研究。 该项目研究了性冲突，精子竞争和伴侣操纵策略在同时雌雄同体香蕉slug中的演变。 交配后，这些sl表现出了阴茎咀嚼的高度不寻常的交配行为，这是对精子竞争的进化反应。Sinervo和Miller对科学外展具有很长的兴趣，并且该项目在非科学观众中非常受欢迎。 另外，由于该项目是劳动密集型的，因此它使他们可以与本科生（主要是妇女）团队紧密合作，并指导他们对科学研究的基础知识。 本科生学习了可以在各种科学领域中使用的各种广泛适用的领域和分子实验室研究技术。
