“…Studies have demonstrated that the volume of urine released is closely linked with aggressive behaviours (Breithaupt et al, 1999) and, after the first encounter, only dominant individuals continue to release urine to maintain their dominance (Breithaupt and Atema, 2000). There is also evidence that lobsters rely on visual signals to recognize each other (Gherardi et al, 2010;Bruce et al, 2018). All these means of communication emphasize the importance of individual-level recognition of submissive and dominant individuals.…”

“…pheromones) released in urine appear to be the main means of preserving the memory of the outcome between pairs of individuals, post-encounter (Breithaupt and Atema, 1993;Karavanich and Atema, 1998;Breithaupt et al, 1999). Recently, Gherardi et al (2010) and Bruce et al (2018) showed that visual recognition of specific individuals also plays a role. The ability to recall the outcome of past encounters may help individual lobsters to avoid additional fights and lower their future risk of injury (Breithaupt and Atema, 2000).…”

Previous studies have demonstrated that male European lobsters (Homarus gammarus) use chemical and visual signals as a means of intraspecific communication during agonistic encounters. In this study, we show that they also produce buzzing sounds during these encounters. This result was missed in earlier studies because low-frequency buzzing sounds are highly attenuated in tanks, and are thus difficult to detect with hydrophones. To address this issue, we designed a behavioural tank experiment using hydrophones, with accelerometers placed on the lobsters to directly detect their carapace vibrations (i.e. the sources of the buzzing sounds). While we found that both dominant and submissive individuals produced carapace vibrations during every agonistic encounter, very few of the associated buzzing sounds (15%) were recorded by the hydrophones. This difference is explained by their high attenuation in tanks. We then used the method of algorithmic complexity to analyse the carapace vibration sequences as call-and-response signals between dominant and submissive individuals. Even though some intriguing patterns appeared for closely size-matched pairs (<5 mm carapace length difference), the results of the analysis did not permit us to infer that the processes underlying these sequences could be differentiated from random ones. Thus, such results prevented any conclusions about acoustic communication. This concurs with both the high attenuation of the buzzing sounds during the experiments and the poor understanding of acoustic perception by lobsters. New approaches that circumvent tank acoustic issues are now required to validate the existence of acoustic communication in lobsters.

“…Most behavioural studies have focused on agonistic encounters in male American lobsters, and have shown that they use chemical and visual signals to communicate dominance status (Karavanich and Atema, 1998;Bruce et al, 2018). In addition, our group recently found that male European lobsters also produce many buzzing sounds during these events (Jézéquel et al 2020a).…”

Although many crustaceans produce sounds, their hearing abilities and mechanisms are poorly understood, leaving uncertainties regarding whether or how these animals use sound for acoustic communication. Marine invertebrates lack gas-filled organs required for sound pressure detection, but some of them are known to be sensitive to particle motion. Here, we examined whether the American lobster (Homarus americanus) could detect sound and subsequently sought to discern the auditory mechanisms. Acoustic stimuli responses were measured using auditory evoked potential (AEP) methods. Neurophysiological responses were obtained from the brain using tone pips between 80 and 250 Hz, with best sensitivity at 80–120 Hz. There were no significant differences between the auditory thresholds of males and females. Repeated controls (recordings from deceased lobsters, moving electrodes away from the brain and reducing seawater temperature) indicated the evoked potentials' neuronal origin. In addition, AEP responses were similar before and after antennules (including statocysts) were ablated, demonstrating that the statocysts, a long-proposed auditory structure in crustaceans, are not the sensory organs responsible for lobster sound detection. However, AEPs could be eliminated (or highly reduced) after immobilizing hairfans, which cover much of lobster bodies. These results suggest that these external cuticular hairs are likely to be responsible for sound detection, and imply that hearing is mechanistically possible in a wider array of invertebrates than previously considered. Because the lobsters' hearing range encompasses the fundamental frequency of their buzzing sounds, it is likely that they use sound for intraspecific communication, broadening our understanding of the sensory ecology of this commercially vital species. The lobsters' low-frequency acoustic sensitivity also underscores clear concerns about the potential impacts of anthropogenic noise.

“…Une étude récente a également démontré la forte production de buzz lors de rencontres agonistiques entre individus mâles (Jézéquel et al, 2020b). L'hypothèse avancée par les auteurs est que ces sons constituent un moyen de conserver la mémoire du résultat entre paires d'individus après une rencontre agonistique, suite à l'apparition d'un dominant et d'un dominé, comme cela a été démontré avec les signaux chimiques et visuels (Karavanich et Atema, 1998 ;Bruce et al, 2018). Cette capacité à rappeler le résultat des rencontres passées aide les homards à éviter des combats supplémentaires et permet ainsi de réduire les risques de blessures (Breithaupt et Atema, 2000).…”

Le chapitre 3, central dans cet ouvrage, propose une étude des effets des sons sur la faune marine et sur les seuils d'impacts. Ces impacts acoustiques, parfois importants, peuvent s'exprimer tout au long du cycle de vie des organismes marins. Ils peuvent induire des réponses biologiques aux différents niveaux d'intégration du vivant, tant sur l'individu (réponses physiologiques et comportementales), que sur les populations et les espèces, ainsi que sur les interactions qui les lient au sein d'assemblage d'espèces (interactions interspécifiques). Ces réponses peuvent varier en fonction du stade de développement (ontogénie), de l'âge ou du sexe, du contexte, mais également en fonction de la distance à la source et des caractéristiques de la source sonore. Dans ce chapitre, en plus des études sur les mammifères marins et sur la faune benthique, nous avons fait le choix de
