Worldwide Soundscapes: A Synthesis of Passive Acoustic Monitoring Across Realms
Darras, Kevin F. A.; Rountree, Rodney A.; Van Wilgenburg, Steven L.; Cord, Anna F.; Pitz, Frederik; Chen, Youfang; Dong, Lijun; Rocquencourt, AgnèsAim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage to gauge its potential as a global research and monitoring tool. ...
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...

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...
Calling activity and calls' temporal features inform about fish reproductive co...
Bolgan, Marta; Crucianelli, A.; Mylonas, C.C.; Henry, S.; Falguière, J.C.; Parmentier, E.; Mollo, ErnestoAlthough many fish species are vocal, the use of fish sounds for aquaculture management and wild population protection has not received much attention. In this study, sound production of three members of the Sciaenidae family was monitored before and during spawning in aquaculture facilities. The species examined include the meagre Argyrosomus regius, the shi dum Umbrina cirrosa and red drum Sciaenops ocellatus...

Temporal dynamics in diversity patterns of fish sound production in the Condor ...
Carriço, Rita; Silva, Mónica A.; Menezes, Gui M.; Vieira, Manuel; Bolgan, Marta; Fonseca, Paulo; Amorim, M. Clara P.Fish sounds are important components of Azorean soundscapes. Therefore, unraveling their patterns can contribute to a better assessment of local biodiversity dynamics. Passive Acoustic Monitoring (PAM) is a cost-effective, non-intrusive method providing long-term information regardless of weather or logistic conditions, which can be especially useful when monitoring remote areas. Using PAM, we assess temporal 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 ...
