Sound production in the Meagre, Argyrosomus regius (Asso, 1801): intraspecific ...
Pereira, David; Vieira, Manuel; Pousão-Ferreira, Pedro; Candeias-Mendes, Ana; Barata, Marisa; Fonseca, Paulo; Amorim, Maria Clara PessoaMany fish taxa produce sound in voluntary and in disturbance contexts but information on the full acoustic repertoire is lacking for most species. Yet, this knowledge is critical to enable monitoring fish populations in nature through acoustic monitoring.
Predicting the effects of anthropogenic noise on fish reproduction
Jong, Karen De; Forland, Tonje Nesse; Amorim, Maria Clara Pessoa; Rieucau, Guillaume; Slabbekoorn, Hans; Sivle, Lise DoksæterAquatic animals use and produce sound for critical life functions, including reproduction. Anthropogenic noise is recognized as a global source of environmental pollution and adequate conservation and management strategies are urgently needed. It becomes therefore critical to identify the reproductive traits that render a species vulnerable to acoustic disturbances, and the types of anthropogenic noise that are...
Continuous but not intermittent noise has a negative impact on mating success i...
Blom, Eva-Lotta; Kvarnemo, Charlotta; Dekhla, Isabelle; Schöld, Sofie; Andersson, Mathias H.; Svensson, Ola; Amorim, Maria Clara PessoaAnthropogenic underwater noise is a global pollutant of increasing concern but its impact on reproduction in fish is largely unknown. Hence, a better understanding of its consequences for this important link to fitness is crucial. Working in aquaria, we experimentally tested the impact of broadband noise exposure (added either continuously or intermittently), compared to a control, on the behaviour and reproduc...
Assessment of fighting ability in the vocal cichlid Metriaclima zebra in face o...
Amorim, Maria Clara Pessoa; Fonseca, Paulo; Mathevon, Nicolas; Beauchaud, MarilynInformation transfer between individuals typically depends on multiple sensory channels. Yet, how multi-sensory inputs shape adaptive behavioural decisions remains largely unexplored. We tested the relative importance of audio and visual sensory modalities in opponent size assessment in the vocal cichlid fish, Metriaclima zebra, by playing back mismatched agonistic sounds mimicking larger or smaller opponents d...
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 ...
Computer-manipulated stimuli as a research tool in Mozambique tilapia Oreochrom...
Wackermannova, Marie Anna; Horky, Pavel; Amorim, Maria Clara Pessoa; Fonseca, Paulo JorgeMultimodal communication is essential in social interactions in cichlid fish, including conspecifics’ recognition, agonistic interactions and courtship behaviour. Computer-manipulated image stimuli and sound playback offer powerful tools to assess the relative relevance of visual and acoustic stimuli in fish behavioural studies, but these techniques require validation for each taxon. The aim of the present stud...
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...
Painted Goby Larvae under high-CO2 fail to recognize reef sounds
Castro, Joana M.; Amorim, Maria Clara Pessoa; Oliveira, Ana P.; Gonçalves, Emanuel João; Munday, Philip L.; Simpson, Stephen D.; Faria, Ana MargaridaAtmospheric CO2 levels have been increasing at an unprecedented rate due to anthropogenic activity. Consequently, ocean pCO2 is increasing and pH decreasing, affecting marine life, including fish. For many coastal marine fishes, selection of the adult habitat occurs at the end of the pelagic larval phase. Fish larvae use a range of sensory cues, including sound, for locating settlement habitat. This study teste...
