Resumo(s)
Communication is essential during social interactions including animal conflicts and it
is often a complex process involving multiple sensory channels or modalities. To better
understand how different modalities interact during communication, it is fundamental
to study the behavioural responses to both the composite multimodal signal and each
unimodal component with adequate experimental protocols. Here we test how an
African cichlid, which communicates with multiple senses, responds to different sensory
stimuli in a social relevant scenario. We tested Maylandia zebra males with isolated
chemical (urine or holding water coming both from dominant males), visual (real
opponent or video playback) and acoustic (agonistic sounds) cues during agonistic
interactions.Weshowed that (1) these fish relied mostly on the visual modality, showing
increased aggressiveness in response to the sight of a real contestant but no responses to
urine or agonistic sounds presented separately, (2) video playback in our study did not
appear appropriate to test the visual modality and needs more technical prospecting,
(3) holding water provoked territorial behaviours and seems to be promising for the
investigation into the role of the chemical channel in this species. Our findings suggest
that unimodal signals are non-redundant but how different sensory modalities interplay
during communication remains largely unknown in fish.
