Abstract IBN 96-23034 Markow and Bertram Role of Selection in Maintaining Variation in Mate Communication Mate communication signals should exhibit minimal variation because they function in species recognition. However, intra-specific variation in mating signals is common. This variation is proposed to result from opposing sexual and natural selection, but few systems are amenable to direct tests of this hypothesis. The specific aim of the proposed research is to determine if selective forces shape observed signal variation in a field cricket. Calling behavior in Gryllus integer is sexually selected, but appears to be subject to natural selection by acoustically orienting parasitoids. To accomplish the specific goal, research will first determine the extent of within-male variation in calling behavior, and whether males facultatively adjust their calling behavior when exposed to parisitoids. Selection experiments will then determine how natural and sexual selection influence inter-male variation in calling behavior over several generations. The proposed research will be the first experimental test of the hypothesis that conflicting selection forces shape mating signals within a population.

摘要IBN 96-23034 MARKOW和伯特拉姆在保持伴侣交流伴侣通信信号的变化中的作用应显示最小的变化，因为它们在物种识别中起作用。 但是，交配信号的特异性变化很常见。 这种变化是由相反的性和自然选择引起的，但是很少有系统可以直接检验该假设。 拟议研究的具体目的是确定选择性力是否形成了板球场中观察到的信号变化。 在Gryllus整数中的称呼行为是性选择的，但似乎通过响应寄生的寄生虫进行自然选择。 为了实现特定目标，研究将首先确定呼叫行为内部差异的程度，以及男性是否会在暴露于parisitoid时会教会其呼叫行为。 然后，选择实验将确定自然和性选择如何影响几代人的呼叫行为之间的男性间变化。 拟议的研究将是对矛盾选择构成人群中交配信号的假设的首次实验检验。
