Acknowledgements The work described in this bookcould be completedthanks to the support and contributions ofmany persons. The whole project, writing a book on the state of the art of modeling and simulating the growth and form of seaweeds,sponges,andstonycorals,wasinitiatedinameetingattheNational Center for Ecological Analysis and Synthesis in Santa Barbara (California) thatweorganizedinAugust1999(seebelow).Thismeetingwasveryinspiring and successful; afterwards we requested several participants to contribute sections in their field of expertise to this book. Weand the contributors would liketothankmanypersons. Bastien Chopard and Peter Sloot wish to thank Alfons Hoekstra and Benno Overeinder from the University ofAmsterdam aswellasAlexandre Masselot and Alexandre Dupuis from the University of Geneva for their contributionand assistanceinpreparingtheirsection.
