“…Overall, our results suggest that the focus on the Tropical Atlantic has directed the scientific research towards studies on coral-algal and coral-sponge community changes (Figures 1b,c LnRR algae/hard coral L nRR soft coral/hard coral L nRR sponge/hard coral 2011; Chan & Hodgson, 2017) and East Africa (Braulik et al, 2017).…”

“…Beyond supporting established survey approaches, PAM also offers unique possibilities, including study of vocalising behaviour, intraspecific variability in call repertoire, and the evolution of acoustic communities (Blumstein et al, 2011;Linhart & Šálek, 2017;Prat, Taub, & Yovel, 2016;Tobias, Planqué, Cram, & Seddon, 2014); animal responses to the acoustic environment (Nowacek et al, 2016;Simpson, Meekan, Jeffs, Montgomery, & McCauley, 2008); and monitoring of anthropogenic phenomena such as sound pollution, blast fishing, and poaching (Astaras, Linder, Wrege, Orume, & Macdonald, 2017;Braulik et al, 2017) ( Table 1). There is a rich literature on the effects of anthropogenic noise on cetacean and increasingly avian populations and behaviour (e.g., Pirotta, Merchant, Thompson, Barton, & Lusseau, 2015;Proppe, Sturdy, & St. Clair, 2013).…”

Emerging opportunities and challenges for passive acoustics in ecological assessment and monitoring

High‐throughput environmental sensing technologies are increasingly central to global monitoring of the ecological impacts of human activities. In particular, the recent boom in passive acoustic sensors has provided efficient, noninvasive, and taxonomically broad means to study wildlife populations and communities, and monitor their responses to environmental change. However, until recently, technological costs and constraints have largely confined research in passive acoustic monitoring (PAM) to a handful of taxonomic groups (e.g., bats, cetaceans, birds), often in relatively small‐scale, proof‐of‐concept studies. The arrival of low‐cost, open‐source sensors is now rapidly expanding access to PAM technologies, making it vital to evaluate where these tools can contribute to broader efforts in ecology and biodiversity research. Here, we synthesise and critically assess the current emerging opportunities and challenges for PAM for ecological assessment and monitoring of both species populations and communities. We show that terrestrial and marine PAM applications are advancing rapidly, facilitated by emerging sensor hardware, the application of machine learning innovations to automated wildlife call identification, and work towards developing acoustic biodiversity indicators. However, the broader scope of PAM research remains constrained by limited availability of reference sound libraries and open‐source audio processing tools, especially for the tropics, and lack of clarity around the accuracy, transferability and limitations of many analytical methods. In order to improve possibilities for PAM globally, we emphasise the need for collaborative work to develop standardised survey and analysis protocols, publicly archived sound libraries, multiyear audio datasets, and a more robust theoretical and analytical framework for monitoring vocalising animal communities.

“…The utilization of new technologies has assisted both governments and non‐state actors in surveillance and monitoring the activities of IUU fishers and fishing vessels (e.g. underwater sound and blast fishing, Braulik et al., 2017). MCS technologies have been found to stimulate new partnerships between state and non‐state actors.…”

Progress and challenges in eliminating illegal fishing

2020

Illegal fishing is a widespread, global phenomenon that is affecting already heavily depleted wild fish stocks, threatening marine habitats and contributing to marine pollution through discarded fishing gear. Many different measures have been implemented by nation states to deter and prevent illegal fishing. These include coastal surveillance and policing, policies and regulation, and education. In this paper, we examine the case of Australia through an analysis of regulative arrangements, policies and guidelines that form the governance framework to better understand the changing seascape of illegal fishing. We argue that joint efforts with neighbouring states such as Indonesia and regional fisheries management authorities have contributed to a decrease in illegal fishing in and around the Australian EEZ. Finally, we discuss current and future challenges, opportunities, recent advancements and technological approaches for reducing illegal fishing around the world.
