DISSERTATION RESEARCH: Offspring-Parent Communication

摘要 IBN 96-23764 Hoy，Crocroft吉尔伯特 亲子沟通 在所有的动物社会中，大多数个体的社会互动都是通过交流进行的。 然而，沟通在社会行为中的作用仍然存在争议，部分原因是很难将有关信号对同一系统中的受试者和受试者的适应意义的信息整合起来。 在亚社会性的树跳，粗角乌氏，父母和子女之间的沟通起着至关重要的作用，他们对捕食的反应。 雌性只生产一窝幼仔，因此父母和后代之间的利益高度重叠，父母在后代防御方面的投资程度。 因此，信令的适应性成本和益处由发送方和接收方共享。 这项研究将通过量化父母的有效性来解决信号的好处 反捕食反应，这是由若虫信号引起的。 信号的成本将通过操纵女性在后代防御中的投资来解决，以确定通过唤起父母防御而获得的当前利益是否会被父母生存率和未来防御潜力的减少所抵消。 拟议的研究应该是动物交流和社会进化领域内的普遍兴趣。

Abstract IBN 96-23764 Hoy, Crocroft & Gilbert Offspring-Parent Communication Within all animal societies, most of an individual s social interactions are carried out by means of communication. Yet the role of communication in social behavior remains controversial, in part because it has been difficult to integrate information about the adaptive significance of signaling for both senders and receivers within the same system. In the subsocial treehopper, Umbonia crassicornis, communication between parents and offspring plays a critical role in their response to predation. Females produce only a single clutch of young, and thus there is a high overlap of interests between parent and offspring about the extent of parental investment in offspring defense. The fitness costs and benefits of signaling are therefore shared by both senders and receivers. This study will address the benefits of signaling by quantifying the effectiveness of the parents anti-predatory response, that is evoked by nymphal signals. The costs of signaling will be addressed by manipulating female investment in offspring defense, to determine whether current benefits accrued by evoking parental defense are offset by a reduction in parental survivorship and potential for future defense. The proposed research should be of general interest within the fields of animal communication and social evolution.
