Acoustic complexity of vocal fish communities: A field and controlled validation
Bolgan, Marta; Amorim, Maria Clara Pessoa; Fonseca, Paulo João; Di Iorio, Lucia; Parmentier, EricThe Acoustic Complexity Index (ACI) is increasingly applied to the study of biodiversity in aquatic habitats. However, it remains unknown which types of acoustic information are highlighted by this index in underwater environments. This study explored the robustness of the ACI to fine variations in fish sound abundance (i.e. number of sounds) and sound diversity (i.e. number of sound types) in field recordings ...
Noise can affect acoustic communication and subsequent spawning success in fish
Jong, Karen de; Amorim, Maria Clara Pessoa; Fonseca, Paulo João; Fox, Clive J.; Heubel, Katja U.There are substantial concerns that increasing levels of anthropogenic noise in the oceans may impact aquatic animals. Noise can affect animals physically, physiologically and behaviourally, but one of the most obvious effects is interference with acoustic communication. Acoustic communication often plays a crucial role in reproductive interactions and over 800 species of fish have been found to communicate aco...
Appraisal of unimodal cues during agonistic interactions in Maylandia zebra
Chabrolle, Laura; Ammar, Imen Ben; Fernandez, Marie S.A.; Boyer, Nicolas; Attia, Joël; Fonseca, Paulo João; Amorim, Maria Clara PessoaCommunication 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...
Sound-production mechanism in Pomatoschistus pictus
Parmentier, Eric; Petrinisec, Maud; Fonseca, Paulo João; Amorim, Maria Clara PessoaFish acoustic signals play a major role during agonistic and reproductive interactions. Among the sound-generating fish, Gobiidae, a large fish family with 1866 valid species, is one of the most studied groups of acoustic fishes, with sound production being documented in a number of species. Paradoxically, the sound-producing mechanism remains poorly studied in this group. The painted goby, Pomatoschistus pictu...
