Language
Because this work integrates a project about conservation and organic farming of Helix pomatia
in Germany, the part concerning research in this species was written in German except for
articles. The general introduction and conclusion as well as the abstract of the study that could
not be published were also translated in English. The joint supervision thesis contract allows this
duality in language choice.

Da diese Arbeit Teil eines Projektes zum Schutz und zur Schneckenzucht von Helix pomatia in Deutschland ist,
wurde der Forschungsteil zu dieser Art auf Deutsch geschrieben, auer die Artikel. Die allgemeine Einleitung und
Schlussfolgerung sowie die Zusammenfassung der Studie, die nicht veröffentlicht werden kann, wurden auch ins
Englische übersetzt. Der binationale Promotionsvertrag erlaubt die Auswahl dieser zwei Sprachen.

Financial support
This work was supported by a grant from the German Federal Environmental Foundation and a
joint thesis subvention from the university Rennes 1. All field experimental work was financed
by the University of Economics and Environment Nürtingen-Geislingen and by the Cooperative
Albschneck®. All laboratory experimental work was financed by the UMR-CNRS 6553 EcoBio
of the University Rennes 1.

Acknowledgement
I’m grateful to my thesis supervisors Maryvonne Charrier, Juliane Filser and Roman Lenz.
Thanks to the team of the university in Nürtingen : Markus and Susanne Röhl, Werner Rolf,
Wolfgang Bortt, Renate Fischer, Manfred Wüstholz, Rainer Mauthe and Joachim Teeuwen.
Thanks to the team from the university in Rennes : Armelle Ansart, Philippe Vernon, Jacques
van Alphen, Sandra Rigaud, Jocelyne Beven, David Renault, Emmanuelle Billard, Jacqueline
Russo, Guénola Perres. Special thanks go to Valérie Briand for documentation, Carole Bertrand
and Anne Pando for their technical help, to Frédéric Magnin and Aude Vialatte for suggestions
on experimental design, to Joseph Le Lannic for electro-microscopic scans, to Patrick Boidé and
Denis Billaud for snail food formulation and fabrication, to Laurent Griscom for language
revision, to Matthias Krebs and Christopher Callahan for some translations, and to Kerstin Rupp
for artwork as well as to the referees. All experimental individuals of Cornu aspersum were
happy snails from the snail farm « Escargotier » in Corps-Nuds, Brittany, and all Helix pomatia
were collected with the help of the snail farmer Manfred Schrimpf and rainy weather. Some
farmed Helix pomatia came from the Snail Farm Institute of Cherasco (Italy). This work would
have never been finished if not supported by my wonderful family: Christoph, Magdalena,
Johanna and Loma, as well as by my parents, grand-parents and friends. Thank you very much.
