WCH 2020 Bioacoustic Abstracts

Symposium Abstract

Studying amphibians in the wild is often difficult and challenging, especially in remote areas, under hard weather conditions and in rugged terrain. However, many amphibians vocalise, which not only serves as a communication tool between individuals but also enables researchers to record them. Acoustic data, collected from species monitoring programs can provide insights into activity levels, functions of communication, acoustic niches, and behaviour among others. The decrease in price of recorders, the advance in technologies such as on-cue automated recordings allow data to be collected from areas that were previously not within reach. The advance of automated data extraction and increase of computing power have led to the potential to collect, store and analyse vast datasets. By integrating new tools and methods into the field, it is now possible to reach a step further and predict behaviour, breeding phenology, population size, individual interactions, and others, which in turn can be used in predicting population fluctuation, breeding behaviour or even conduct population viability analyses. Such findings would inform conservation practitioners towards mitigating threats to this greatly endangered group of animals. Here we aim to highlight the diversity of use of bioacoustics in amphibian research and how new tools and techniques can be used to further the field.

Symposium Justification

Bioacoustic research is a rapidly expanding field. It is also non-invasive and consequently highly important for the conservation of amphibian species. Considering the lack of resources for amphibian monitoring in a number or regions around the world, this is a potentially cost-effective addition to manual audio-visual encounter surveys. The area of bioacoustics also provide valuable insights into areas such as evolution of acoustic niches, functionality of sound and behaviour. Providing updates from this area and potentially new direction or uses of the data is of high importance.
