“…Soundscape cues may be more likely to induce settlement of larvae that have already reached reefs, rather than be used for long-distance navigation. Currents and olfactory cues may act to bring larvae to reefs over longer distances Paris et al, 2013;Suca et al, 2020). However, we lack particle motion sensitivity data for pre-settlement stage invertebrates and fishes, which may have different sensitivities from adults.…”

“…Each of these groups utilize sound for a myriad of ecological functions, including detection and avoidance of predators, foraging, navigation, and communication with conspecifics in reproductive or competitive contexts (Au & Hastings, 2008;Hughes et al, 2014;Ladich, 2019;Popper et al, 2001;Radford, Stanley, et al, 2011;Tricas & Boyle, 2014;Webster et al, 1992). Ambient sounds from natural habitats also induce settlement behavior in many pelagic invertebrates and fishes (Gordon et al, 2019;Lillis, Apprill, et al, 2018;Lillis et al, 2013;Stanley et al, 2012;Suca et al, 2020).…”

“…"Ecoacoustics", or the study of natural soundscapes and their connections to acoustic ecology, is an emerging and rapidly growing research field (Farina & Gage, 2017). Among underwater soundscapes, those of coral reefs have received substantial attention due to their complexity and the diversity of soniferous (sound-producing) coral reef inhabitants (Lobel et al, 2010;Tricas & Boyle, 2014), and growing interest in how coral reef sounds are utilized by preadult fishes and invertebrates as settlement cues (Gordon et al, 2018;Lillis, Apprill, et al, 2018;Suca et al, 2020). There is strong motivation to apply soundscape data to monitor and predict changes in community structure of reefs and other underwater habitats, for example by finding links between traditional non-acoustic indicators of reef health and acoustic characteristics of their soundscapes, or even using reef sounds to encourage fish settlement as part of reef restoration (Gordon et al, 2019;Mooney, Iorio, et al, 2020).…”

“…Reef soundscapes may aid pelagic larvae and juveniles of coral reef taxa navigating toward reefs (Radford, Stanley, et al, 2011). Numerous studies have demonstrated phonotaxis (movement toward sound) and increased settlement when exposed to reef sounds, of corals (Lillis, Apprill, et al, 2018;Lillis et al, 2016), oysters (Lillis et al, 2013), crabs (Stanley et al, 2010(Stanley et al, , 2011(Stanley et al, , 2012, and reef fishes (Gordon et al, 2018;Parmentier et al, 2015;Suca et al, 2020). To sound-sensitive taxa, biological soundscape cues provide critical ecological information about the presence and intent of predators, competitors, prey, and potential mates (Farina & Gage, 2017).…”

“…These reefs have been the focus of ecological research for decades (Edmunds, 2013;Edmunds et al, 2020). Recent studies focusing on sound pressure have investigated multiple facets of soundscape ecology at these sites, including temporal variability , across-reef spatial variability (Lillis, Caruso, et al, 2018), patterns in snapping shrimp activity , settlement behavior of corals (Lillis, Apprill, et al, 2018), larval fish settlement (Suca et al, 2020), and boat noise patterns (Dinh et al, 2018;. These studies provide valuable observations based on sound pressure, with which we can compare trends in particle motion data.…”

Assessing anthropogenic noise impacts and relevant soundscape cues for marine invertebrates: leveraging squid and coral reefs as model systems

Sound is utilized by marine animal taxa for many ecologically important functions, and these taxa are vulnerable to adverse effects of anthropogenic noise on hearing and behavior. However, little is known about marine invertebrates’ responses to anthropogenic noise, and the ambient environmental sounds (“soundscapes”) they detect and respond to. Most acoustic studies report sound pressure (detected by mammals and some fish), but few report particle motion, the back-and-forth vibratory component of sound detected by marine invertebrates. I investigated invertebrate use of and response to sounds in two facets: 1) behavioral responses of longfin squid, Doryteuthis pealeii to anthropogenic noise, and 2) particle motion of coral reef soundscapes in the U.S. Virgin Islands. In laboratory-based experiments I exposed D. pealeii to construction noise originally recorded from an offshore wind farm. I found significant increases in squids’ alarm responses and in failed prey capture attempts during noise. Conversely, noise exposure had no significant effects on reproductive behaviors of groups of D. pealeii, indicating high motivation of these squid to reproduce during this stressor. Collectively, these experiments revealed the importance of considering behavioral context in studies and regulatory decisions regarding invertebrates’ susceptibility to anthropogenic noise impacts. In studying coral reef soundscapes, I reported particle motion trends over several months for coral reefs varying in habitat quality, including coral cover and fish abundance. I found acoustic properties over which particle motion closely scaled with pressure, and others over which it did not. I compared soundscape data with particle motion hearing thresholds, and found that invertebrates may only detect high amplitude and low frequency transient sound cues on reefs, such as those produced by fishes. My research bring new insights on natural and anthropogenic sound cues detectable by marine invertebrates, and how and when invertebrates will be vulnerable to anthropogenic noise pollution.

Anthropogenic noise disrupts acoustic cues for recruitment

Anthropogenic noise is rising and may interfere with natural acoustic cues used by organisms to recruit. Newly developed acoustic technology provides enriched settlement cues to boost recruitment of target organisms navigating to restoration sites, but can it boost recruitment in noise-polluted sites? To address this dilemma, we coupled replicated aquarium experiments with field experiments. Under controlled and replicated laboratory conditions, acoustic enrichment boosted recruitment by 2.57 times in the absence of anthropogenic noise, but yielded comparable recruitment in its presence (i.e. no boosting effect). Using the same technique, we then tested the replicability of these responses in real-world settings where independently replicated ‘sites’ are unfeasible owing to the inherent differences in soundscapes. Again, acoustic enrichment increased recruitment where anthropogenic noise was low (by 3.33 times), but had no effect at a site of noise pollution. Together, these coupled laboratory-to-field outcomes indicate that anthropogenic noise can mask the signal of acoustic enrichment. While noise pollution may reduce the effectiveness of acoustic enrichment, some of our reported observations suggest that anthropogenic noise per se might also provide an attractive cue for oyster larvae to recruit. These findings underscore the complexity of larval behavioural responses to acoustic stimuli during recruitment processes.

Marine soundscapes provide important navigational cues to dispersing larvae in search of suitable habitat. Yet, widespread habitat loss has degraded marine soundscapes and their functional role in recruitment. Habitat restoration efforts can provide suitable substrate for habitat regeneration, such as constructing reefs to facilitate recruitment and habitat growth by oysters, but typically occur where soundscapes are degraded and recruitment is limited. Enhancing marine soundscapes on newly constructed reefs using speaker technology may ensure sufficient recruitment to establish a trajectory of recovery for the desired habitat. Across two of the largest oyster reef restorations in Australia, we deployed low‐cost marine speakers at four sites and at three times throughout the recruitment season to test whether soundscape enrichment could boost recruitment and habitat formation by oysters. In the presence and absence of soundscape playback, we compared oyster recruitment rates to settlement panels across space and time, and oyster habitat cover and three‐dimensional habitat building on newly constructed boulder reefs. On the settlement panels deployed across the two reef restorations, soundscape playback significantly increased oyster recruitment at 8 of the 10 sites by an average (±1 SE) 5.1 ± 1.9 times (5281 ± 1384 more larvae per m2), and by as much as 18 times. On boulders atop newly constructed reefs, where the restoration goal is for oysters to form three‐dimensional habitat, the surface area covered by oysters after 5 months did not differ between speaker and control treatments. However, soundscape playback appeared to influence the earlier recruitment of oysters, resulting in significantly more large oysters per boulder that formed significantly more three‐dimensional habitat building by an average 4.3 ± 1.2 times relative to nonspeaker controls. Synthesis and applications. Our results show that using speakers to enrich marine soundscapes at new restoration sites can boost oyster recruitment, resulting in more larger oysters that form more three‐dimensional habitat atop reef restorations. In accelerating the formation of these vertical growth forms, which provide the ecological functions that motivate restoration efforts, the early application of speaker technology on new reef restorations may help steer ecological succession on a trajectory of desired habitat recovery, potentially reducing the substantial cost of ongoing intervention.
