Outline of Final Research Achievements

The overall goal of this project was to develop an acoustic monitoring program on Okinawa to measure biodiversity and test hypotheses about its response to anthropogenic disturbance. I installed recorders at 24 sites across the main island of Okinawa, maintained in collaboration with the Okinawa Environmental Observation Network (OKEON). In a proof of concept, I demonstrated my ability to compare biodiversity across time and space using soundscape indices, and to automatically detect bird species. Subsequent analyses have addressed the three principal aims of this grant: (1) to estimate alpha diversity using bioacoustics, (2) to compare acoustic beta diversity among urban and rural sites, and (3) to map the spatial distribution of sound across Okinawa. I show that acoustic diversity decreases with disturbance, and that urban sites are more different from each other than rural sites. Beyond publications, I used public events and museum exhibits to communicate my results to the public.

Academic Significance and Societal Importance of the Research Achievements

My study began a natural history archive that is a record of Okinawa’s biodiversity. I demonstrated a proof of concept for acoustic monitoring, and addressed three ecological questions. My research was reported to society by publications, lectures, a museum exhibit, and several media appearances.
