Última Are communication activities shaped by environmental constraints in reverberating and absorbing forest habitats? Anais da ABC (AABC) Manthevon,Nicolas; Aubin,Thierry; Dabelsteen,Torben; Vielliar,Jacques M.E.. In the dense vegetation of temperate or tropical forests, communication processes are constrained by propagation-induced modifications of the transmitted sounds. The presence of leaves, trunks and branches induces important sound reverberation and absorption leading to diminution of the signal energy as well as qualitative modifications. The aim of this paper is to briefly review the different strategies used by birds to manage with these constraints. At the emitter's level, an adapted emission behavior which takes into account both the physical heterogeneities of the forest environment and the temporal variations of the acoustic constraints, is especially useful to control the active space of signaling. The coding of information into acoustic parameters...
