Conservation Biology Congress 2016


River Listening is featured at the 2016 Society for Conservation Biology Oceania Congress in a symposium titled “Continuous monitoring of invisible places: bioacoustics in marine and freshwater environments”

DATE: July 6, 2016
TIME: 2:30 pm – 4:00 pm
Brisbane Convention and Entertainment Centre

Monitoring aquatic species in underwater environments – rivers, lakes and oceans – has proven even more difficult than terrestrial surveys of endangered taxa. Traditional methods of aquatic survey techniques bear a) risks to fish health and habitat integrity, b) introduce bias, because it might cause fright responses in key aquatic species and c) standard surveying only produces a snapshot from the time of surveying – which in many cases does not happen more than once a year and d) it can be very expensive, particularly in areas with remote access. Non-invasive passive bioacoustic monitoring can address all four problems. This special session will explore novel techniques in aquatic bioacoustics that can aid conservation managers. Topics will range from holistic ecosystem monitoring (Linke, Gifford) to descriptions of detailed algorithms with which soniferous aquatic taxa can be detected. The symposium will also include talks on the challenges of using acoustical data for monitoring populations and on protocols for monitoring and mitigating impacts of noise. The final talk by Dr Leah Barclay will cover bioacoustics as a tool for engaging with the public. We hope that this first session in freshwater and marine bioacoustics at a continental or worldwide SCB conference will raise awareness and kickstart increased joint efforts by marine and freshwater scientists to establish bioacoustics monitoring as a key survey method.

What is ecoacoustics?

Ecoacoustics is an interdisciplinary science that investigates natural and anthropogenic sounds and their relationship with the environment over a wide range of study scales, both spatial and temporal, including populations and communities. Ecoacoustics operates in all types of terrestrial and aquatic (freshwater and marine) ecosystems extending the scope of acoustics and bioacoustics.

Ecoacoustics recognizes that sounds can be both the subject and tools of ecological research. As the subject, sounds are investigated in order to understand their evolution, functions and properties under environmental pressures. As tools, sounds are used to study and monitor animal diversity, abundance, behaviour, dynamics and distribution, and their relationship with ecosystems and the environment.
