‘The Changing Song of the Sea: Soundscapes as indicators and drivers of ecosystem transition on tropical coral reefs’
The idea addressed by Tim’s thesis is that environmental change in coral reef communities is reflected in their soundscapes, which in turn provide cues to larval fishes about where to settle, and so influence how reefs recover following coral bleaching events. Tim’s thesis tests this idea, and whether it can be deployed to the good of reef restoration. It shows, using field data from the Great Barrier Reef, that coral bleaching depletes reef soundscapes; that these reduced soundscapes are in turn less attractive for settlement by fish larvae needed to recolonise these habitats; that passive acoustic monitoring of reef soundscapes can monitor the success of reef restoration; that experimental playback of the soundscapes of healthy reefs can accelerate their recolonisation; and that this positive effect is different from that of restoring the structural complexity of reefs. Tim has had two of his thesis chapters published in very high-profile journals. Between the chapters are drawings and poems by children and other members of the public in response to the many outreach activities he carried out. The writing and presentation of Tim’s theses shines with enthusiasm for the natural history of the habitats it concerns.
