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. ...
Turning up the heat: Effects of temperature on agonistic acoustic communication...
Penim, Jorge; Beauchaud, Marilyn; Millot, Morgane; Faria, Ana M.; Vieira, Manuel; Fonseca, Paulo; Vasconcelos, Raquel O.; Amorim, M. Clara P.Acoustic communication is linked to fitness traits in many animals, but under the current scenario of global warming, sound signals can be affected by rising temperatures, particularly in ectothermic organisms such as fishes. This study examines the effect of water temperature in acoustic communication in the two-spotted goby, Pomatoschistus flavescens. To address this, we looked at the effect of different temp...
Acoustic fish community in the Madeira Archipelago (North Atlantic Ocean): Char...
Muñoz-Duque, Sebastian; Fonseca, Paulo; Quintella, Bernardo; Monteiro, João Gama; Fernandez, Marc; Silva, Rodrigo; Vieira, Manuel; Amorim, M. Clara P.Marine ecosystems are increasingly subjected to anthropogenic pressures, which demands urgent monitoring plans. Understanding soundscapes can offer unique insights into the ocean status providing important information and revealing different sounds and their sources. Fishes can be prominent soundscape contributors, making passive acoustic monitoring (PAM) a potential tool to detect the presence of vocal fish sp...
Cross-referencing unidentified fish sound data sets to unravel sound sources: a...
Vieira, Manuel; Ríos, Noelia; Muñoz-Duque, Sebastian; Pereira, Jodanne; Carriço, Rita; Fernandez, Marc; Monteiro, João G.; Pais, Miguel PessanhaThere is growing evidence that studying aquatic acoustic communities can provide ecologically relevant information. Understanding these communities may offer unique insights into species behaviour and ecology, while consolidating passive acoustic monitoring as a tool for mapping the presence of target species or estimating changes in aquatic biodiversity. Fish can be significant soundscape contributors, but mos...
First assessment of passive acoustics as a tool to monitor the endangered Medit...
Muñoz‐Duque, Sebastian; Vieira, Manuel; Fonseca, Paulo; Quintella, Bernardo; Charrier, Isabelle; Monteiro, João Gama; Fernandez, Marc; Silva, Rodrigo1. The rarest seal and the world's most endangered pinniped species, the Mediterranean monk seal (Monachus monachus), has a small and isolated population in the Madeira Archipelago (Portugal). This species tends to be extremely wary of humans and, therefore, very difficult to approach and study. 2. Passive acoustic monitoring (PAM) is a non-invasive, cost-effective tool that can be a valuable complement for the...
Impact of anthropogenic noise on the survival and development of meagre (Argyro...
Trabulo, Rita; Amorim, M. Clara P.; Fonseca, Paulo J.; Vieira, Manuel; Matos, Manuel J. B.; Marin-Cudraz, Thibaut; Lemos, Marco F.L.; Novais, Sara C.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 ...
Detection of invasive fish species with passive acoustics: Discriminating betwe...
Amorim, M. Clara P.; Wanjala, Joan A.; Vieira, Manuel; Bolgan, Marta; Connaughton, Martin A.; Pereira, Beatriz P.; Fonseca, Paulo; 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...

Effects of temperature on acoustic and visual courtship and reproductive succes...
Albouy, Robin; Faria, Ana M.; Fonseca, Paulo; Amorim, M. Clara P.Fish 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, M. 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...
