Workshop 5 – Novel approaches to bat acoustic analysis

When: Wednesday 9:45am to 12pm

Organisers: Greg Ford (Balance! Environmental, greg@balance-environmental.com.au); Julie Broken-Brow (University of Queensland, julie.brokenbrow@uqconnect.edu.au)

This workshop will explore emerging techniques for processing large volumes of microbat echolocation data and alternative approaches to identifying and monitoring bat species and communities through bioacoustics. Presenters will discuss topics ranging from foraging and social call structure, to automated processing of bulk recordings and the use of bat recordings in soundscape analyses.  A series of short presentations will be followed by a panel discussion on topics raised and potential applications.

Presentations include

Kyle Armstrong (Specialized Zoological, South Australia) – Pioneering exploration of Papua New Guinea’s nocturnal ultrasonic realm using a flexible semi-automated approach to processing bulk recordings

Julie Broken-Brow (University of Queensland) – The use of novel acoustic methods to answer ecological questions: A case study examining the effect of fire-return interval on bats by assessing the nocturnal ultrasonic soundscape

Michael Towsey (Queensland University of Technology, Ecoacoustics Research Group) – False-colour spectrographic analysis of long-duration bioacoustic recordings: a case study using bat echolocation.

Nicola Hanrahan (Hawkesbury Institute for the Environment, Western Sydney University) – Hearing ghosts: automatic classification of social vocalisations to monitor abundance and behaviour in a threatened bat species

Greg Ford (Balance! Environmental, Toowoomba, Qld) – Bat foraging calls: help or hindrance in echolocation analysis?
