Eco-acoustics: stakes, theory, tools & methods (Field Trip) (Weeks 4 & 8, 6 ECTS)

 

This two-week module will consist of a field trip at the heart of the Jura Natural Park followed by one week in the lab. We will review the science behind eco-acoustics.  We will see the principles, methods and applications of this exciting emerging field. We will see how we can assess the biodiversity based on sounds emanating from a variety of species and environments. We will analyse the relationship between eco-acoustics and bioacoustics while also addressing key concepts such as landscape ecology and behavioural ecology. We will also discuss the areas for potential future research in eco-acoustics including challenges in species conservation and soundscape conservation. In the mornings, key theoretical notions will be presented by specialist speakers and each afternoon a more practical part will be carried. During this field- and computer-based practical sessions we will review cutting edge methods and tools for the implementation of a study for the analysis of song and for the measurement of biodiversity, including the spatiotemporal sampling strategy.

Research talks on, e.g.,  the use of eco-acoustic methods to survey the impacts of climate change on biodiversity, on the analysis of the acoustic functionality of ecological corridors, or on soundscape conservation will expose students directly to current research in these fast-expanding areas of eco-acoustics.

Assessment

The final mark of this module will be based on a small research project involving the tools and methods, and data that were introduced during the two weeks.  Each group of four students will produce a poster and present it orally (20 minutes per group, 5 minutes per student). The mark will reflect the quality of the common poster and the quality of the individual oral delivery.

Organisers and tutors : F. Sèbe.

Tutors: Y. Bas, S. Haupert, C. Huetz & J. Sueur.

Demonstrators: A. Guibard

Learning outcomes

By the end of the module, a successful student should be able to:

1. Record soundscapes and measure biodiversity from soundscapes.

2. Demonstrate a good understanding of tools for analysing soundscapes. 

3. Demonstrate familiarity with main issues and current topics relating to eco-acoustics and challenges in species conservation and soundscape conservation.
