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.

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.阿隆索广泛的研究集中在解释物种内部和物种之间的多样性。男性的替代性生殖行为是种群中个体差异最引人注目和研究最充分的例子之一。然而，关于这种离散变异如何在种群中维持，仍然存在争论。有两个关键因素很少受到注意，但需要加以考虑。首先，人们普遍认为，雄性之间的竞争通常会导致雄性行为的离散变异进化。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。其次，女性生殖模式的离散变化被观察到，但目前还没有理论预测女性的替代生殖行为何时会进化，以及预计会出现什么样的模式。这项研究将发展一种通用的理论方法，并产生新的理论来研究性别内部和性别之间的相互作用如何影响性别多样性的模式。对生殖行为个体差异的进一步了解在养护、渔业和管理方面具有广泛的应用。本研究还将训练两名本科生和一名研究生使用各种模型。
