abstract = "The influence of social context in animal signals can lead to
complex communicational patterns. In particular, the interaction
between individuals can lead to intriguing collective dynamics,
such as the temporal synchronization of signals. A fascinating
example of such temporal synchronization involves the waving
displays of fiddler crabs, in which males raise and lower their
enlarged claws in species-specific rhythms. The adaptive
significance of this phenomenon is still obscure, but possibly
involves female preference for leading waving displays. However,
waving displays are highly complex social signals that might be
involved in a variety of forms of communication other than simply
attracting females, but little is known about the influence of
social context on wave synchronization. In this study we carried
out field experiments to investigate the effect of two social
factors, male density and female presence, on the level of waving
synchronization in the fiddler crab Uca leptodactyla. Groups of
males at varying densities were established in enclosures and
recorded either in the presence or absence of a female. Our
results indicate that the main factor driving synchronization is
the presence of the female, with males not only changing the
timing of their waving displays, but also altering their spatial
distribution in the arenas. On the other hand, male density had a
negligible effect on synchronization (despite significantly
increasing waving rate), suggesting that malemale communication
plays a minor role in the emergence of waving synchronization in
this species.",
