Synchronous waving in two species of fiddler crabs

Synchronous waving in two species of fiddler crabs 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png acta ethologica Springer Journals

Abstract

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.
