In accordance with the main purpose of the meeting, senior scientists, postdoctoral investigators and graduate students working in areas of descriptive and experimental embryology, classical, molecular and developmental biology, physiology and biochemistry etc., were brought together for two weeks as a community with a strong common interest in "development"; that is, the multiple phenomena and mechanisms, in molecular, cellular, genetic and organismic terms, observed in the development of aquatic organisms. Initial concern that the great variety of biological models as well as of research subjects would harm the scientific quality and coherency of the course was unnecessary. It was exactly this breadth which made the Institute worthwhile for each of the participants. Since many of the "students" were younger scientists starting a career, it was the main goal of the course to offer a concise overview of selected system models of primarily aquatic organisms and to present and discuss research carried out in the past and in progress. Thus, each main speaker gave two in-depth lectures: one in which he presented an overview of "his" model and another dealing with current investigations. As to their contributions for this book, it was at each individual author's discretion to present his/her knowledge in the form of one manuscript or, as had been done orally, in two distinct chapters. In addition, a few participants were also invited to write short manuscripts. The models that were presented span the range from the unicellular algae to complex vertebrate embryos. Each model has its own properties and specific value which makes it suitable for a particular type of research. For example, whereas algae or coelenterates are highly suitable for studies on cell polarity determination, ooplasmic segregation, nucleo-cyto plasmic interactions or pattern formation phenomena, control mechanisms on oocyte maturation and fertilization events are classically best analyzed in echinoderms and ascidians. Planarians proved uniquely suitable for regeneration studies and molluscs give essential insight into compartmentalization processes in embryonic tissues. Representatives of annelids are of great interest for basic neurobiological research, and fish embryos are worthy of note for the study of cell migration in vivo, etc. In particular, this book contains chapters on research done on the following model systems: v Uni- and pluricellular algae by S. Berger and R. Quatrano; Coelenterates (hydroids and ctenophores) by G. Plickert and Ch. Sardet; Turbellaria (planarians) and nematodes (Caenorhabiditis elegans, living on a water film) by J. Baguna and E. Schierenberg; Molluscs by J. Van den Biggelaar and H. -J. Marthy; Annelids (leeches and polychaetes) by S. Blackshaw and A. Dorresteijn; Echinoderms (starfish and urchins) by L. Meijer and R. Burke; Chordates (tunicates) by B. Dale and W. Jeffery; Vertebrates (teleost fishes) by J.P. Trinkaus and R. Fleig. It is also interesting to remember the historical and conceptual framework in which "causal embryology" is anchored (J .L. Fischer). For their high general scientific and stimulating value, the book contains finally chapters on research work done on avian eggs (G. Eichele:morphogens; P. Kucera: physiological approaches to embryogenesis; embryos' sensitivity against environmental factors). They should provide a "challenge" for encouraging similar research on and/or methodological approaches to eggs and embryos of aquatic organisms. Twenty years have passed since Reverberi' s book on "Experimental Embryology of Marine and Fresh-water Invertebrates" was published and became a standard reference book for developmental biology. It is the intention of the editor and the authors of this book that the information contained herein should not only update some of the research reported there, but by introducing new original aspects, prove to be invaluable as a contemporary reference work for research scientists, teachers and students alike. I take the opportunity to thank the NATO Scientific Affairs Committee for having supported this ASI and, in particular, the Director of the ASI Programme Dr. L.V. da Cunha. I also want to thank the lecturers of the course and all the "students" for their great efforts in making it a real success. Thanks belong also to the Director of the Laboratoire Arago, ~rofessor A. Guille, for hospitality. Important organizational and administrative work has been done by Mrs. N. Clara and Mr. C. Febvre. The diligent work of Mrs. U. Marthy Stampfli, who prepared the manuscript in camera-ready form is greatly acknowledged.
