Animal synchrony is found in phylogenetically distant animal groups,
indicating behavioural adaptations to different selective pressures and in
different signaling modalities. A notable example of synchronous display
is found in fiddler crabs in that males wave their single enlarged claw
during courtship. They present species-specific signals, which are
composed of distinctive movement signatures. Given that synchronous waving
has been reported for several fiddler crab species, the display pattern
could influence the ability of a given species to sufficiently adjust wave
timing to allow for synchrony. In this study we quantified the wave
displays of fiddler crabs to predict their synchronous behaviour. We
combined this information with the group’s phylogenetic relationships to
trace the evolution of display synchrony in an animal taxon. We found no
phylogenetic signal in interspecific variation in predicted wave
synchrony, which mirrors the general non-phylogenetic pattern of synchrony
across animal taxa. Interestingly, our analyses show that the phenomenon
of synchronization stems from the peculiarities of display pattern, mating
systems and the complexity of microhabitats. This is the first study to
combine mathematical simulations and phylogenetic comparative methods to
reveal how ecological factors and the mechanics of animal signals affect
the evolution of the synchronous phenomena.
