Use of the acoustic descriptors as environmental proxies to study spatio-temporal soundscape variations, organism-environment relationships
Our research activity concerns the description of each soundscape component (biophony, geophony and antropophony) and their interactions to infer information on the structure, state, functioning and dynamics of an ecosystem. Among the main subjects are organism-environment relationships at different ecological scales including the study of:
- the biophony, from invertebrates to fish and marine mammals, in terms of organisms’ activity (through movements, behaviours, etc.), biodiversity (taxonomic level), abundance, biorythms, and spatio-temporal variations. Biophony can be considered as a proxy of biological traits that can be monitored at high resolution and over long time periods.
Invertebrate and fish sound diversity – link to species and/or behaviours
- environmental responses :
- linking biophony and anthropophony or biophony and other anthropogenic activities, which may have a negative (e.g., pollution, fisheries, etc.) or a positive (e.g., natural reserves, etc.) effect on the marine fauna and its environment,
- linking biophony and geophony as well as biophony and other physical and oceanographic phenomena.
