Kirkpatrick 9407969 This project will investigate the mechanisms for the diversification of mating displays and mating preferences between closely related species. These traits are known to diversify at a very high rate and therefore represent a model system for studies of the factors responsible for behavioral differences both within and between the species. The investigators will use mathematical models that describe genetic change in mating displays, mating preferences, and other traits that are genetically coupled to them. Research will focus on three mechanisms: (1) direct survival effects of mating preferences (the "direct selection" hypothesis), (2) genetic coupling between traits that increase survival and mating preferences (the "good genes" hypothesis), and (3) mate choice copying. Recent experimental data show that all three mechanisms influence preferences and displays, but have not evaluated their relative importance. Mathematical models developed in this research program will use data to produce the first quantitative estimates of the relative impacts of these mechanisms. Results will produce insights into the causes of behavioral variation and the processes of speciation.

Kirkpatrick 9407969该项目将研究与密切相关物种之间交配显示和交配偏好多样化的机制。 已知这些特征会以很高的速度多样化，因此代表了一种模型系统，用于研究导致物种内部和物种之间行为差异的因素。 研究人员将使用数学模型来描述交配显示，交配偏好和其他遗传耦合的其他性状的遗传变化。 研究将侧重于三种机制：（1）交配偏好的直接存活效应（“直接选择”假设），（2）增加生存和交配偏好的性状之间的遗传耦合（“好基因”假设）和（3）Mate选择复制。 最近的实验数据表明，这三种机制都会影响偏好和显示，但尚未评估它们的相对重要性。 在本研究计划中开发的数学模型将使用数据来产生这些机制相对影响的第一个定量估计。 结果将对行为变化和物种过程的原因产生见解。
