ABSTRACT Nowicki & Weiss IBN 96-23869 Functional Analysis of Female Reproductive Coloration Female choice, male-male mate competition, and resulting sexually dimorphic traits have been a primary focus in studies of animal behavior. Relatively new to the field of animal behavior is the concept that species with conventional sex-roles may exhibit female-female mate competition and male choosiness. Such reproductive patterns may be an important selective force in the evolution of communication signals. This proposal proposes a study of the communicative function of female reproductive coloration in the sexually dimorphic lizard, Sceloporus virgatus (Sauria: Iguanidae). It will be determined whether this coloration is used in female-female mate competition, functioning to attract choosy males into a female s home range during her receptive period. To test this and other hypotheses concerning the function of female reproductive coloration, this research will (1) determine how changes in coloration and display behavior are temporally associated with seasonal changes in reproductive state, (2) determine whether aspects of female quality are correlated with color patch characteristics, and (3) experimentally examine the effect of female coloration and display behavior on the behavior of conspecific males using a choice test paradigm.

摘要Nowicki&Amp；Weiss IBN 96-23869对雌性生殖着色、雌性选择、雄性-雄性配偶竞争以及由此产生的性二型性状的功能分析一直是动物行为研究的主要焦点。在动物行为领域，相对较新的概念是，具有传统性别角色的物种可能会表现出雌雄竞争和雄性挑剔。这种繁殖模式可能是通讯信号进化中的一种重要的选择力量。这项建议提出了一项研究雌性生殖色彩在性二型蜥蜴Scelopus virgatus(蜥蜴：鬣蜥科)中的交流功能。将确定这种颜色是否用于雌雄之间的竞争，在S接受雌性的过程中，它的作用是吸引挑剔的雄性进入雌性猎场。为了验证这一假设和其他关于雌性生殖着色功能的假设，本研究将(1)确定着色和展示行为的变化如何与生殖状态的季节性变化相关联，(2)确定雌性质量的各个方面是否与色块特征相关，以及(3)使用选择测试范式来实验检验雌性着色和展示行为对同种雄性的行为的影响。
