ENVIRONMENTAL ACOUSTIC RESEARCH (EAR) – Objectives
long-term (> years) monitoring oftropical acoustic diversity to
(1) estimate and track extreme terrestrial acoustic diversity(2) assess acoustic variations within and between years
(3) correlate acoustics variations with global changes

. temporal and spatial acoustic heterogeniety assess with acoustic indices on a 3D audio sampling of the tropical forest
. automatic tracking of the singing activity of a focal species, the bird Lipaugus vociferans
