7 - 2- Welcome Address of the Organizers Dear colleagues, we are very pleased that you accepted our invitation to come to Regensburg to attend the 102 nd annual meeting of the Deutsche Zoologische Gesellschaft in the Darwinian Year Charles Darwin's theory of evolution provides the foundation of modern biology and its diverse subdisciplines. Therefore we have attempted to commemorate the 200th birthday of Darwin and the 150th anniversary of the publication of "The Origin of Species" through the selection of renowned main speakers. Through your participation the meeting will reflect the entire breadth and meaning of modern zoology. There are also other excellent reasons to come to Regensburg. After all it has been 30 years since the DZG met last in Regensburg saw the 1,800 th anniversary of the city's founding by the Roman Emperor, Marcus Aurelius, as the garrison "Castra Regina" was also noteworthy because eight years prior the first students had begun their studies in biology at the young University of Regensburg. In the meantime, many things have changed. The Regensburg old town has obtained UNESCO World Heritage status. An honorary professor of the theology faculty has even become Pope. As you will see, the University buildings are being renovated, and the first students have obtained their bachelors degrees. We hope you will enjoy the conference and your stay in Regensburg! The Members of the Institute of Zoology

9 - 4- General Information Conference Venue The conference venue will be the Audimax building on the campus of University of Regensburg. Access to campus / maps A map of the campus can be found on the back cover page, and a schematic map on one of the last pages of this program booklet indicates the location of the lecture halls. The conference venue can be reached from the city centre and the main station by busses 6 (direction Klinikum) and 11 (direction Burgweinting / Sophie-Scholl-Straße). Exit at Universität Mensa. The stops of busses 6 and 11 are indicated on the maps. Please note that busses 6 and 11 with direction city centre leave the stop Universität Mensa in opposite directions: bus 6 leaves towards the east (bus stop across the street from Audimax; direction Wernerwerkstraße), bus 11 towards the west (bus stop in front of Audimax, direction Roter-Brach-Weg). We have been promised that the basement garage will be open during the conference times. Other parking areas are indicated on the maps. However, please be aware that alcoholic beverages will be offered during the reception and the poster session.
