A Coevolutionary Theory of Male and Female Alternative Reproductive Behaviors: Combining Phenotypic and Genetic Aapproaches

雄性和雌性选择性生殖行为的共同进化理论：结合表型和遗传方法苏珊娜·H·阿隆索深入研究侧重于解释物种内和物种间的多样性。雄性另类生殖行为是种群内个体差异最显著和研究最充分的例子之一。然而，关于这种离散变异是如何在种群中保持的，仍然存在争议。有两个关键因素没有得到多少关注，但需要加以考虑。首先，人们普遍认为，男性之间的竞争通常会导致男性行为的离散变异的进化。然而，女性的行为和两性之间的互动也会影响男性的生殖行为。第二，观察到了女性生殖模式的离散变异，但目前还没有理论来预测女性替代生殖行为预计何时会演变，以及预计会出现什么模式。这项研究将开发一种一般的理论方法，并产生新的理论，研究性别内部和性别之间的互动如何影响性别内的多样性模式。对生殖行为个体差异的更多了解在养护、渔业和管理中具有广泛的应用。这项研究还将培训两名本科生和一名研究生使用各种建模。

A Coevolutionary Theory of Male and Female Alternative Reproductive Behaviors: Combining Phenotypic and Genetic ApproachesSuzanne H. AlonzoExtensive research has focused on explaining diversity within and between species. Male alternative reproductive behaviors are one of the most striking and well-studied examples of individual variation within a population. However, debate still exists regarding how this kind of discrete variation is maintained in populations. Two critical factors exist that have received little attention but need to be considered. First, it is generally assumed that competition between males usually leads to the evolution of discrete variation in male behavior. However, female behavior and interactions between the sexes can also affect male reproductive behavior. Second, discrete variation in female reproductive patterns is observed, but currently no theory exists predicting when female alternative reproductive behaviors are expected to evolve and what patterns are expected. This research will develop a general theoretical approach and generate new theory that examines how interactions within and between the sexes affect patterns of diversity within a sex. An increased understanding of individual variation in reproductive behavior has broad application to conservation, fisheries and management. This research will also involve training two undergraduate students and one graduate student in the use of various modeling.
