Dear All, _Both registration and abstract submission_ are now open for the XXIII meeting of the _ __International BioAcoustic Coucil (IBAC)_ that will be held in the city of La Rochelle, France, from 12-16 September 2011 at the Aquarium. __ The objective of IBAC meeting is to promote international participation throughout the entire field of bioacoustical activity. The subject of bioacoustics is principally a marriage between the fields of biology and physical acoustics. Given its multidisciplinary nature, IBAC aims to bring together, in informal settings, biologists from different specialisms (ethologists, physiologists, taxonomists, etc) with engineers, sound archivists and amateur sound recordists, to foster discussion and exchange of ideas. The scientific program will be composed of sessions of invited speakers integrated with thematic symposia and poster presentations. More information are available on the following website: http://www.cb.u-psud.fr/ibac2011 We hope to see you in La Rochelle next September !
