Message from the Chair

John P. Wourms

I am composing this message in the waning days of August while contemplating this summer's efforts in research, writing and attendance at conferences and also preparing for the fall semester. Traditionally, this is a time of taking stock and looking toward the future. The June issue of American Zoologist contained the proceedings of our 1995 symposium, "Forces in Developmental Biology Research: Then and Now" organized by Louise Luckenbill-Edds. Several more of our symposia should be appearing soon. The task ahead of us, and it is a pleasant one, is to prepare for the SICB 1998 Annual Meeting in Boston, Jan. 3-7, 1998. Except for a few comments on the meeting, most of the newsworthy items will be found in the accompanying reports of our secretary and program chair. I also look forward to working with Scott Gilbert, our new chair-elect.

Before the SICB 1998 Annual Meeting begins, there will be a pre-meeting of a new group, the Julia B. Platt Club, on Jan. 2. This group is being established to provide a forum for evolutionary morphology and development. Our meeting date was changed from late December to January to avoid conflict with family celebrations of the holiday season. I encourage all members to attend the meeting. There are no excuses now.

Boston, which has long been a center for intellectual and scientific activity, is a fine site for a meeting. An outstanding program has been planned. Our division is sponsoring or co-sponsoring several symposia. There are at least four symposia that will be of interest to cell developmental biologists: "Comparative Embryology of Myogenesis," "Evolution of

the Steroid/Thyroid/Retinoic Acid Receptor Family," "Aquatic Organisms, Terrestrial Eggs: Early Development at the Water's Edge," and "Development and Evolutionary Perspectives on Major Transformations in Body Organization."

There will be a number of contributed paper sessions sponsored by divisions and also several interdivisional sessions, one of which is "Reproduction and Life Cycles." Encourage fellow faculty and graduate students to attend. The SICB Annual Meeting provides a unique forum where individuals interested in cell developmental biology, comparative embryology and evolutionary developmental biology can gather and exchange ideas.

The past two years have been marked by the passing of many members of the Old Guard. Their memorial notices have appeared in these pages and elsewhere. Because I knew one and studied with the other, I have been affected by the deaths of N.J. Berrill and Keith Porter. Neither was active in SICB, but through their research activities and scholarly accomplishments, they had a profound effect in shaping the field of cell and developmental biology. One is saddened by the loss of friends, mentors and role models. Some consolation can be found in the knowledge that their spirits live on in the rich intellectual legacy that they bequeathed us.

Message from the Program Officer

Billie J. Swalla

Greetings from the DDCB Program Officer!

It's the time of year that we are very busy scheduling symposia and contributed papers for the upcoming SICB 1998 Annual Meeting in Boston, Jan. 3-7, 1998. We thank you all for sending in your abstracts on time.

This year promises to be a great meeting for DDCB. We received nearly three times the number of contributed papers that we had last year. DDCB is co-sponsoring two symposia and the symposium organizers Judy Venuti, Lennart Olsson and Brian Hall have been working very hard all summer, communicating with speakers and obtaining funding. In addition, Damhnait McHugh at Harvard University and Ken Halanych at Rutgers University are organizing an additional symposium on "Evolutionary Relationships of Metazoan Phyla: Advances, Problems and Approaches" (Jan. 5-6), which will have a number of speakers also interested in evolution of body plans. Look up the speakers on the SICB Web site:

Be sure to thank these symposia organizers for their efforts when you see them in Boston. In addition, we would like to thank the speakers who have committed to participating even if not fully funded. I think it underlines the fact that we do our science well because we love our work, and we continually seek new ideas and interactions. I know this will be a productive and exciting meeting for all who attend it and I hope to see you there! Enjoy.

Message from the Secretary

Charles H. Ellis, Jr.

There is little new to report since the spring. The division membership is currently listed as 201, placing us only fifth among the ten SICB divisions. As our molecular approaches bring us back to important comparative and evolutionary questions, the field's paradigm shift ought to make our division attractive to new members. Of course it is we, the current members, who must make our colleagues and students aware of what we can offer as a community of integrative developmental biologists. Our symposia for the Boston meeting are concrete examples of what we offer that is often lacking in other more specialized venues. Each of us should try to attend, to bring our students to the meeting, and to interest colleagues in joining us.

Next spring, we will hold elections for two officer positions as Billie Swalla and I progress toward the ends of our respective terms. The Nominating Committee will be appointed at or after the SICB 1998 Annual Meeting, but I am sure that John Wourms would welcome advance suggestions for potential candidates for program officer-elect and secretary (or Nominating Committee volunteers - the sure way to control your own fate). Ballots will be distributed in the spring 1998 newsletter.

I look forward to seeing many of you in January. Bring your concerns and ideas so that we have a lively business meeting and I will have a lot of items for the minutes. If you have ideas on how this newsletter space can be made more useful, or if you wish to submit something to be included in these pages, please contact me.

Three New Books

Charles H. Ellis, Jr., DDCB Secretary

In recent months two major new books have been published, each in its own way providing a new look at comparative and evolutionary issues in development. Also a new edition of one of the major developmental biology textbooks came out during the summer. These three works certainly speak to the integrative and comparative aspect of our science.

Described in flyers as the first comparative embryology textbook in a century, Embryology: Constructing the Organism, edited by Scott Gilbert and Anne Raunio provides up-to-date descriptive and experimental information on the development of nearly every major invertebrate and vertebrate group. The chapter authors, many of whom are or have been active in SICB, also examine evolutionary implications of the developmental patterns discussed. This text is aimed toward an undergraduate course and is published by Sinauer Associates.

Another book that brings forth the information and ideas involved in the developmental paradigm shift is Cells, Embryos and Evolution by John Gerhart and Marc Kirschner. It was given a detailed review by Tony Mahowald in Science (vol 277: 772-773, August 8, 1997). The book focuses on the conservation of developmental mechanisms, among them cell surface - matrix interactions and signaling systems, relating them to development of body plans across the phyla. The publisher is Blackwell Science.

We are all familiar with one of the favorite current texts, Developmental Biology, by Scott Gilbert. Scott has revised and updated it as the fifth edition, published once again by Sinauer Associates. In addition to the book's detailed coverage of all the key areas of developmental biology, Scott has made even more information and graphics available on the Web site

I would be happy to receive word of other relevant new books to include in future newsletters.

Scott Gilbert Chosen as Chair-Elect

The results of the election for chair-elect were tabulated by the SICB office in June; Scott F. Gilbert of Swarthmore College was elected to serve as chair-elect in 1998 and lead DDCB in 1999-2000. In the balloting, Scott and Andy Cameron were separated by only a few votes. We were lucky to have such strong candidates, both of whom are so committed to DDCB and the integrative aspects of cellular developmental biology.
