“…Several studies have highlighted that settling fishes can detect and respond to reef sound (e.g. Leis et al, , 2003Simpson et al, 2004;Tolimieri et al, 2000Tolimieri et al, , 2004Leis and Lockett, 2005;Mann et al, 2007). However, understanding this process is more complicated than it appears.…”

Just after the reef colonization, fish species could use the acoustic cue to settle on different suitable habitats. In the present study, we used the auditory evoked potential (AEP) technique to measure and compare the detection abilities in five coral reef fish species, with some of these species that are found in the same habitat. We also examined the effect of fish size on sensitivity at the species level. All studied species except one showed size-related changes in sensitivity characterized by either a decrease (i.e. higher AEP thresholds) or an increase (i.e. lower AEP thresholds) in detection abilities with increasing size. The interspecific comparison of audiograms revealed that some species are more sensitive than others in terms of sound pressure level and frequency detection. Overall, this study indicates that the AEP threshold and the frequency bandwidth at early life stages may vary between and within fish species. The detection abilities are different in fish species that are not phylogenetically related, which might suggest that the establishment of their capabilities is not necessarily related to the reef conquest.

“…Several behavioral experiments have suggested that larval fish may use reef sound to identify a suitable settlement habitat (e.g., Tolimieri et al, 2000Tolimieri et al, , 2004Simpson et al, 2004Simpson et al, , 2005Radford et al, 2011a). Most fishes without specialized morphological adaptations cannot hear frequencies higher than around 1000 Hz (Popper and Fay, 2011), and the majority of fish calls are often below 1000 Hz (Tricas and Boyle, 2014).…”

“…Within-reef variability is also not well understood, but such an investigation is needed to determine how best to evaluate a soundscape. Given that settlement-stage fishes and invertebrates have been shown to use sound to locate and orient to settlement sites (Tolimieri et al, 2000(Tolimieri et al, , 2004Simpson et al, 2004Simpson et al, , 2005Vermeij et al, 2010;Radford et al, 2011a), site-specific soundscapes may allow these animals to identify suitable habitats.…”

Coral reef soundscapes : spatiotemporal variability and links to species assemblages

Coral reefs are biodiverse ecosystems that are at risk of degradation as a result of environmental changes. Reefs are constantly in a state of flux: the resident species assemblages vary considerably in space and time. However, the drivers of this variability are poorly understood. Tracking these changes and studying how coral reefs respond to natural and anthropogenic disturbance can be challenging and costly, particularly for reefs that are located in remote areas. Because many reef animals produce and use sound, recording the ambient soundscape of a reef might be one way to efficiently study these habitats from afar. In this thesis, I develop and apply a suite of acoustics-based tools to characterize the biological and anthropogenic acoustic activity that largely comprises marine soundscapes. First, I investigate links between reef fauna and reef-specific acoustic signatures on coral reefs located in the U.S. Virgin Islands. Second, I compare those findings to a more expansive study that I conducted in Maui, Hawaii, in which the drivers of bioacoustic differences among reefs are explored. Third, I investigate the distances over which sounds of biological origin may travel away from the reef and consider the range within which these acoustic cues might be usable by pelagic larvae in search of a suitable adult habitat. Fourth, I assess the extent to which the presence of vessel noise in shallow-water habitats changes the ambient soundscape. Finally, I present the results of a modeling exercise that questions how ocean noise levels might change over the next two decades as a result of major projected increases in the number and size of and distance traveled by commercial ships. The acoustics-based tools presented here help provide insight into ecosystem function and the extent of human activity in a given habitat. Additionally, these tools can be used to inform an effective regulatory regime to improve coral reef ecosystem management.

“…For each experiment, the percent time spent at each cue was first calculated (based on a total of 15 min). The middle part of the aquarium represented lack of attraction to either of the 2 simultaneous cues offered and was therefore not incorporated into the statistical tests (Tolimieri et al 2004). Time spent at each cue and in the middle compartment always totaled 100%.…”

Most coastal marine organisms have a dispersive oceanic larval stage, during which they must be able to distinguish and respond to relevant environmental cues when settling into their first benthic habitat. Chemical stimuli emanating from settlement habitats and being dispersed by water plumes could enable long-distance navigation by larval reef fish, but we know little about the cues responsible and their interactive effects. In the present study, we tested this by conducting several ex situ choice experiments in which the response of the coral reef fish Lutjanus fulviflamma towards different chemical cues from coastal habitats was tested close to their settlement stage. Fish preferred seagrass habitat water over that from coral reef and mangrove habitats. Furthermore, fish were attracted to chemical cues from their own species (conspecifics) and other fish species, as well as vegetation of 4 different seagrass species, when offered in isolation (i.e. soaked in neutral water), but a strong response remained only towards cues from conspecifics and seagrass leaves when these cues were mixed with seagrass habitat water that naturally contains other cues. Hierarchical effects were observed as fish preferred chemical cues from seagrass leaves over those from conspecifics when both were offered at the same time. The importance of visual habitat cues only overruled that of chemical cues when it concerned preferred cues (i.e. seagrass as opposed to mangrove cues). Our findings indicate that pelagic fish and settlers possess the ability to use multiple reliable chemical cues to locate suitable early life stage habitats, although the importance of these cues is context-dependent. Nevertheless, this flexibility in choice behavior is probably an adaptive strategy to enhance fitness by increasing successful orientation towards preferred settlement habitats.
