We are pleased to announce that the 5th Animal Sonar Symposium will be held from September 14 to 18, 2009, in Kyoto, Japan. This meeting has been held approximately every 10 years very successfully at Frascati (1966), Jersey (1979), Helsingor (1986), and Algarve (1998). We invite you to participate in this meeting. We provide contributed poster sessions that anyone can join. Big afternoon poster sessions are designed for the discussion among participants. Not only biosonar research but also any bioacoustic subjects are welcome to join us. The best presenter(s) will be awarded. All of the contributed papers will be peer reviewed. In the morning session, over 40 invited presenters will update their results in biosonar research. Good papers will be published after the symposium. Further details are below. http://cse.fra.affrc.go.jp/akamatsu/AnimalSonar.html Cheers, Hiroshi Riquimaroux (chair) and Tom Akamatsu (secretary) ------------------------------------ Tomonari AKAMATSU http://nrife.fra.affrc.go.jp/akamatsu/
