Theories of sexual signalling have been developed largely without reference to life-history theory and quantitative genetics. We will test recent theory that shows the costs of signals are best measured in units of future survival and reproduction. In a series of field and laboratory experiments on the cricket Teleogryllus commodus, we will test the idea that the "male genetic quality" referred to by good-genes models of sexual selection is quality in the general ability to acquire resources, rather than in how resources are allocated among fitness components.

性信号的理论在很大程度上是在没有参考生活史理论和数量遗传学的情况下发展起来的。我们将测试最近的理论，该理论表明，信号的成本最好以未来的生存和繁殖为单位来衡量。在对板球进行的一系列野外和实验室实验中，我们将检验这样一种观点，即性选择的好基因模型所指的“雄性遗传质量”是指获取资源的一般能力的质量，而不是资源在健康组成部分之间如何分配的质量。
