             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.",
