- Revealing chronotypes across aquatic species using acoustic telemetryPublication . Martorell‐Barceló, Martina; Abecasis, David; Akaarir, Mourad; Alonso‐Fernández, Alexandre; Arlinghaus, Robert; Aspillaga, Eneko; Barcelo‐Serra, Margarida; Brevé, Niels W. P.; Davidsen, Jan G.; Gamundí, Antoni; Grau, Amalia; Hereu, Bernat; Jarić, Ivan; Kapusta, Andrzej; Lowerre‐Barbieri, Sue; Monk, Christopher T.; Nickel, Anja K.; Nicolau, María C.; Ólafsdóttir, Guðbjörg Á.; Olsen. Esben M.; Pickholtz, Renanel; Prchalová, Marie; Reubens, Jan; Říha, Milan; Knaap, Inge van der; Verhelst, Pieterjan; Villegas‐Ríos, David; Alós, JosepAcoustic telemetry offers valuable opportunities to investigate individual variability in circadian-related and other behaviours and how environmental cues shape these patterns in wild fish populations. However, this potential has not yet been fully exploited. We conducted a meta-analysis on 44 datasets from 34 distinct marine and freshwater species and different types of data (acoustic detections, depth, acceleration and positioning). Our aim was to explore the potential of acoustic telemetry in identifying chronotypes as consistent among-individual differences in circadian-related behaviours. First, we applied hidden semi-Markov models to classify individual time series into active and rest states. Subsequently, we computed two classical circadian-related behavioural traits: awakening time (as the activity onset) and rest onset (as the activity offset). Subsequently, we identified distinct phenotypes by decomposing behavioural variation into within- and among-individual components based on repeatability scores. We found evidence of distinct chronotypes in 17 species, with average repeatability scores of 0.52 for awakening time and 0.43 for rest onset, revealing that chronotypes are common in aquatic species. Our findings highlight that both the data type, particularly acceleration sensors, and the number of detections are effective tools for exploring chronotypes. Our study proposes a novel approach to characterising daily activity patterns in aquatic species, predominantly in fishes, and provides guidelines for investigating chronotypes across diverse taxa. We emphasise the promise of biotelemetry and advanced statistical models for improving our understanding of the behaviour of aquatic species and highlight the value of synthesising across large data sets collected in networks of biotelemetryprojects.
- A review of acoustic telemetry in Europe and the need for a regional aquatic telemetry networkPublication . Abecasis, David; Steckenreuter, Andre; Reubens, Jan; Aarestrup, Kim; Alós, Josep; Badalamenti, Fabio; Bajona, Lenore; Boylan, Patrick; Deneudt, Klaas; Greenberg, Larry; Brevé, Niels; Hernández, Francisco; Humphries, Nick; Meyer, Carl; Sims, David; Thorstad, Eva B.; Walker, Alan M.; Whoriskey, Fred; Afonso, PedroBackground Globally, there are a large and growing number of researchers using biotelemetry as a tool to study aquatic animals. In Europe, this community lacks a formal network structure. The aim of this study is to review the use of acoustic telemetry in Europe and document the contribution of cross-boundary studies and inter-research group collaborations. Based on this, we explore the potential benefits and challenges of a network approach to identify future priorities and best practices for aquatic biotelemetry research in Europe. Results Over the past decade, there was an approximately sevenfold increase in the number of acoustic telemetry studies published on marine and diadromous species in Europe compared to a sixfold increase globally. Over 90% of these studies were conducted on fishes and undertaken in coastal areas, estuaries, or rivers. 75% of these studies were conducted by researchers based in one of five nations (Norway, UK, France, Portugal, and Spain) and, even though 34% were based on collaborations between scientists from several countries, there was only one study with an acoustic receiver array that extended beyond the borders of a single country. In recent years, acoustic telemetry in European waters has evolved from studying behavioural aspects of animals (82.2%), into more holistic approaches addressing management-related issues (10%), tagging methods and effects (5%), and technology and data analysis development (2.8%). Conclusions Despite the increasing number of publications and species tracked, there is a prominent lack of planned and structured acoustic telemetry collaborations in Europe. A formal pan-European network structure would promote the development of (1) a research platform that could benefit the acoustic telemetry community through capacity building, (2) a centralized database, and (3) key deployment sites and studies on priority species requiring research in Europe. A network may increase efficiency, expand the scope of research that can be undertaken, promote European science integration, enhance the opportunities and success of acquiring research funding and, ultimately, foster regional and transatlantic collaborations. It may also help address research priorities such as the large-scale societal challenges arising from climate change impacts and assist the EU’s Marine Strategy Framework Directive via identification of good environmental status of endangered or commercially important species.
- Toward a decade of ocean science for sustainable development through acoustic animal trackingPublication . Alós, Josep; Aarestrup, Kim; Abecasis, David; Afonso, Pedro; Alonso‐Fernandez, Alexandre; Aspillaga, Eneko; Barcelo‐Serra, Margarida; Bolland, Jonathan; Cabanellas‐Reboredo, Miguel; Lennox, Robert; McGill, Ross; Özgül, Aytaç; Reubens, Jan; Villegas‐Ríos, DavidThe ocean is a key component of the Earth's dynamics, providing a great variety of ecosystem services to humans. Yet, human activities are globally changing its structure and major components, including marine biodiversity. In this context, the United Nations has proclaimed a Decade of Ocean Science for Sustainable Development to tackle the scientific challenges necessary for a sustainable use of the ocean by means of the Sustainable Development Goal 14 (SDG14). Here, we review how Acoustic animal Tracking, a widely distributed methodology of tracking marine biodiversity with electronic devices, can provide a roadmap for implementing the major Actions to achieve the SDG14. We show that acoustic tracking can be used to reduce and monitor the effects of marine pollution including noise, light, and plastic pollution. Acoustic tracking can be effectively used to monitor the responses of marine biodiversity to human-made infrastructures and habitat restoration, as well as to determine the effects of hypoxia, ocean warming, and acidification. Acoustic tracking has been historically used to inform fisheries management, the design of marine protected areas, and the detection of essential habitats, rendering this technique particularly attractive to achieve the sustainable fishing and spatial protection target goals of the SDG14. Finally, acoustic tracking can contribute to end illegal, unreported, and unregulated fishing by providing tools to monitor marine biodiversity against poachers and promote the development of Small Islands Developing States and developing countries. To fully benefit from acoustic tracking supporting the SDG14 Targets, trans-boundary collaborative efforts through tracking networks are required to promote ocean information sharing and ocean literacy. We therefore propose acoustic tracking and tracking networks as relevant contributors to tackle the scientific challenges that are necessary for a sustainable use of the ocean promoted by the United Nations.
- Tracking aquatic animals for fisheries management in European watersPublication . Özgül, Aytaç; Birnie‐Gauvin, Kim; Abecasis, David; Alós, Josep; Aarestrup, Kim; Reubens, Jan; Bolland, Jon; Lök, Altan; Edwards, Jena E.; Pengal, Polona; Prchalová, Marie; Říha, Milan; Pickholtz, Renanel; Vollset, Knut Wiik; Afonso, Pedro; Davidsen, Jan Grimsrud; Arlinghaus, Robert; Ünal, Vahdet; Lennox, Robert J.Acoustic telemetry (AT) has emerged as a valuable tool for monitoring aquatic animals in both European inland and marine waters over the past two decades. The European Tracking Network (ETN) initiative has played a pivotal role in promoting collaboration among AT researchers in Europe and has led to a significant increase in the number of tagged and observed aquatic animals in transboundary European waters. While AT benefits decision-making and delivers essential data to management bodies, its potential for management decision-making mechanisms has yet to be fully harnessed. We reviewed existing research, studies, and organisational initiatives related to aquatic animal tracking and their utility in fisheries management in European waters. We found that AT has already contributed to many aspects of fisheries management, such as improved understanding of stock dynamics, identification of critical habitats, assessment of migration routes, and evaluation of the effectiveness of conservation measures. However, broader utilisation of tracking technologies is needed. By leveraging the full potential of AT, managers can make more informed decisions to protect, restore, and sustainably manage European waters and creatures that live therein.
