RESEARCH INTERESTS

Analysis and Monitoring of animal biodiversity using passive acoustics

My PhD started in November 2009 (CNRS INEE PhD Grant). This work is co-supervised by Jérôme Sueur, Sandrine Pavoine (UMR 7204) and Philippe Grandcolas.
Biodiversity measurement is an urgent but challenging task. A non-invasive, inexpensive and fast method was developed to infer local diversity through the analysis of animal sound. Indices of acoustic complexity have been proposed previously in Sueur et al., PLos ONE, 2008. The first part of my work is to test these indices and to specify what kind of biodiversity information can be extracted through a global analysis of acoustic complexity. The second part of my research will consist of applying this method in biological conservation context. Agroforestry is a potential refuge for tropical biodiversity that is threatened by habitat lost due to deforestation. The impact of these farming practices need a better understanding. In India, two types of coffee agroforestry, preserving or not native trees, will be compared in term of biodiversity using the acoustic complexity indices.

Key-Words : biodiversity, bioacoustics, conservation, tropical forest, ecological indicators
