侵略性信号的作用，包括其信息内容和在何种情况下导致冲突的解决或升级，仍然是有争议的。我们研究了攻击性的歌曲的信息内容的房子蟋蟀，Acheta alticus，测试他们的能力，告知对手的战斗能力和动机。我们发现，个别男性所产生的歌曲是高度可重复的，并包含有关男性资源持有潜力的信息，男性赢得一个积极的比赛的能力。攻击性歌曲的时间成分与男性的身体大小，大小影响的强度和结果的战斗。相比之下，我们没有发现歌曲的组成部分，信号的动机，以争取。虽然男性与配偶的访问受到限制显着更具侵略性，赢得了战斗更频繁，他们的歌曲并没有反映出不对称的动机，以争取。我们讨论了动物比赛中缺乏动机信号的可能原因。(c)2006年，动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
The function of aggressive signals, including both their information content and the circumstances under which they cause resolution or escalation of conflict, continues to be controversial. We studied the information content of aggressive songs in the house cricket, Acheta domesticus, to test their ability to inform opponents about fighting ability and motivation. We show that songs produced by individual males are highly repeatable and contain information about male resource holding potential, the ability of a male to win an aggressive contest. Temporal components of aggressive song were correlated with male body size, and size affected both the intensity and outcome of fights. In contrast, we found no components of song that signal motivation to fight. Although males with restricted access to mates were significantly more aggressive and won fights more often, their songs did not reflect the asymmetry in motivation to fight. We discuss possible reasons for the absence of signals of motivation during animal contests. (c) 2006 The Association for the Study of Animal Behaviour. Published by Elsevier Ltd. All rights reserved.
