在招潮蟹Uca saltitanta和Uca perplexa中，雄性招潮蟹通过挥舞它们放大的爪子来吸引配偶。我们表明，在这两个物种的挥动是密切同步相邻的男性集群之间，无论是在存在的求偶女性，并在他们的缺席。游荡的雌性拜访那些在集群中以更快的波浪率产生更多波浪的雄性。在us除了perplexa之外，它们还会选择性地拜访那些产生最多主导波的雄性。同步摆动可能是一种优先效应的结果，导致男性竞争产生领先的信号。
In the fiddler crabs Uca saltitanta and Uca perplexa, males attract mates by waving their enlarged claws. We show that in both species waving is closely synchronised between neighbouring males in clusters, both in the presence of mate-searching females and in their absence. Wandering females visit those males in the cluster that produce more waves at faster wave rates. In U. perplexa, they also selectively visit those males that produce the greatest number of leading waves. Synchronous waving may be the result of a precedence effect causing male competition to produce leading signals.
