The amazonian tropical forest is one of the richest ecosystem on Earth producing complex soundscapes with intricate sounds of mammals, amphibians, birds and arthropods.
We run long term and one-shot research programs in the Nouragues Reserve in French Guiana, more specifically at CNRS Nouragues field research station.

We mainly aim at monitoring and understanding the local acoustic diversity. To do that, we designed temporary audio samplings and a permanent recording station in the COPAS zone where the CNRS offers an access to the canopy. Here, we will document the phenology of the soundscape, of specific acoustic communities and populations. This will be linked with weather data to estimate the possible impacts of climate changes on tropical ecosystems.
