Detection of invasive fish species with passive acoustics: Discriminating betwe...
Amorim, Maria Clara P; Wanjala, Joan A.; Vieira, Manuel; Bolgan, Marta; Connaughton, Martin A.; Pereira, Beatriz P.; Fonseca, Paulo J.; Ribeiro, FilipeInvasive alien species have been rising exponentially in the last decades impacting biodiversity and ecosystem functioning. The soniferous weakfish, Cynoscion regalis, is a recent invasive sciaenid species in the Iberian Peninsula and was first reported in the Tagus estuary in 2015. There is concern about its possible impacts on native species, namely the confamiliar meagre, Argyrosomus regius, as there is over...
Impact of anthropogenic noise on the survival and development of meagre (Argyro...
Trabulo, Rita; Amorim, Clara; Fonseca, Paulo J.; Vieira, Manuel; Matos, André B.; Marin-Cudraz, Thibaut; Lemos, Marco F.L.; Moutinho, Ariana B.The growth of human populations has been driving an unprecedent and widespread increase in marine traffic, posing a real threat to marine biodiversity. Even though we are now aware of the negative effects of shipping noise exposure on fish, information about the impact on their early life stages continues to lack. Meagre (Argyrosomus regius) is a vocal fish that uses estuaries with high levels of anthropogenic ...
Effects of temperature on acoustic and visual courtship and reproductive succes...
Albouy, Robin; Faria, Ana M.; Fonseca, Paulo J.; Amorim, ClaraFish are ectothermic and small changes in water temperature could greatly affect reproduction. The two-spotted goby is a small semi-pelagic species that uses visual and acoustic displays to mate. Here, we studied the effect of temperature (16 and 20 ◦C) on acoustic and visual courtship and associated reproductive success in 39 males. Temperature influenced male visual courtship performed outside the nest, but i...

Boat noise impacts Lusitanian toadfish breeding males and reproductive outcome
Amorim, Maria Clara P; Vieira, Manuel; Meireles, Gabriela; Novais, Sara C; Lemos, Marco F.L.; Modesto, Teresa; Alves, Daniel; Zuazu, Ana; Lopes, Ana F.Anthropogenic noise is a growing threat to marine organisms, including fish. Yet very few studies have addressed the impact of anthropogenic noise on fish reproduction, especially in situ. In this study, we investigated the impacts of boat noise exposure in the reproductive success of wild Lusitanian toadfish (Halobatrachus didactylus), a species that relies on advertisement calls for mate attraction, using beh...

Vocal repertoire and consistency of call features in the meagre Argyrosomous re...
Bolgan, Marta; Pereira, Beatriz P.; Crucianelli, Aurora; Mylonas, Constantinos C; Pousão-Ferreira, Pedro; Parmentier, Eric; Fonseca, Paulo J.Passive Acoustic Monitoring (PAM) is a non-intrusive and cost-effective method capable of providing high-resolution, long-term information on the status and health of vocal populations and communities. To successfully monitor the same species over wide geographical and temporal scales, it is necessary to characterise the range of sound variability, as well as the consistency of sound features between population...
Sound production in the Meagre, Argyrosomus regius (Asso, 1801): intraspecific ...
Pereira, Beatriz P.; Vieira, Manuel; Pousão-Ferreira, Pedro; Candeias-Mendes, Ana; Barata, Marisa; Fonseca, Paulo J.; Amorim, Maria Clara P.Many 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.
Acoustic barriers as an acoustic deterrent for native potamodromous migratory f...
Jesus, Joaquim; Amorim, Maria Clara P.; Fonseca, Paulo J.; Teixeira, Amílcar; Natário, Silvestre; Carrola, João; Varandas, Simone; Pereira, Luís TorresThis study focused on the use of sound playbacks as acoustic deterrents to direct native potamodromous migratory species away from all kind of traps. The effects of two acoustic treatments, a repeated sine sweep up to 2 kHz (sweep-up stimulus) and an intermittent 140 Hz tone, were tested in three fish species native to Iberia: Salmo trutta, Pseudochondrostoma duriense and Luciobarbus bocagei. In contrast with S...
