Dear Colleagues, The organizers wish to extend a cordial invitation to participate in the 4th International Berlin Bat Meeting: Movement ecology of bats to be held from 13-15 March 2015, in Berlin, Germany. With this conference, we aim at fostering an exchange of ideas among international specialists working on bats in the context of movement ecology. We are especially keen on crossing disciplinary boundaries and hope that the discussion among ecologists, morphologists, theoreticians, physiologists and conservationists will advance the field substantially. We suggest several exciting topics as sessions or workshops. In addition, we have invited plenary speakers to review novel applications and exciting developments in their respective research areas. Please check the details in the attached first call. We are expecting a stimulating program with many interesting scientific presentations supplemented by an entertaining evening program. Please feel free to distribute this call to anyone you think might be interested in participating. We apologize in case you received this letter more than once.
