Anthropogenic noise impacts are pervasive across taxa, ecosystems and the world. Here, we experimentally test the hypothesis that protecting vulnerable habitats from noise pollution can improve animal reproductive success. Using a season-long field manipulation with an established model system on the Great Barrier Reef, we demonstrate that limiting motorboat activity on reefs leads to the survival of more fish offspring compared to reefs experiencing busy motorboat traffic. A complementary laboratory experiment isolated the importance of noise and, in combination with the field study, showed that the enhanced reproductive success on protected reefs is likely due to improvements in parental care and offspring length. Our results suggest noise mitigation could have benefits that carry through to the population-level by increasing adult reproductive output and offspring growth, thus helping to protect coral reefs from human impacts and presenting a valuable opportunity for enhancing ecosystem resilience. Using a season-long field manipulation with an established model fish system on the Great Barrier Reef, this study demonstrates that limiting motorboat activity on reefs leads to faster growth and survival of more fish offspring compared to reefs experiencing busy motorboat traffic. Noise mitigation and abatement could therefore present a valuable opportunity for enhancing ecosystem resilience.

Recreational SCUBA diving is widespread and increasing on coral reefs worldwide. Standard open-circuit SCUBA equipment is inherently noisy and, by seeking out areas of high biodiversity, divers inadvertently expose reef communities to an intrusive source of anthropogenic noise. Currently, little is known about SCUBA noise as an acoustic stressor, and there is a general lack of empirical evidence on community-level impacts of anthropogenic noise on coral reefs. Here, we conducted a playback experiment on Caribbean reefs to investigate impacts of SCUBA noise on fish communities and interspecific cooperation at ecologically important cleaning stations of the Pederson’s cleaner shrimp Ancylomenes pedersoni . When exposed to SCUBA-noise playback, the total occurrence of fishes at the cleaning stations decreased by 7%, and the community and cleaning clientele compositions were significantly altered, with 27% and 25% of monitored species being affected, respectively. Compared with ambient-sound playback, SCUBA-noise playback resulted in clients having to wait 29% longer for cleaning initiation and receiving 43% less cleaning; however, cheating, signalling, posing and time spent cleaning were not affected by SCUBA-noise playback. Our study is the first to demonstrate experimentally that SCUBA noise can have at least some negative impacts on reef organisms, confirming it as an ecologically relevant pollutant. Moreover, by establishing acoustic disturbance as a likely mechanism for known impacts of diver presence on reef animals, we also identify a potential avenue for mitigation in these valuable ecosystems.

Rewilding initiatives are increasing in number across Europe and the UK in response to a growing awareness of substantial nature depletion, despite a lack of policy, guidance and legislation. Ongoing transformations of UK environmental policies offer a ‘policy window’ in which rewilding could become established as a key strategy for nature recovery. Here, we present the results of discussion sessions held as part of a British Ecological Society Policy Training workshop. A total of 46 participants, academics, practitioners and young people interested in rewilding attended. Our discussion focused on three pre‐determined thematic discussion sessions: (1) barriers to rewilding and trade‐offs; (2) species reintroductions; (3) facilitating rewilding in policy. Using thematic analysis, four emerging cross‐cutting themes were identified from our workshop discussions: (a) environmental stewardship & public engagement, (b) cross‐policy approaches, (c) incentivising rewilding and (d) an evidence base for rewilding. Policy Implications. Given the UK's considerable biodiversity loss, restoring ecosystem processes and function on a large scale is increasingly urgent, and operationalising rewilding through supportive environmental policy structures should be a key priority for government.
