DDCB: 1997 Spring Newsleter

This Newsletter by Section

Message from the Chair

John P. Wourms

The pleasure of assuming the Chair's duties at the SICB 1996 Annual Meeting in Albuquerque was lessened by the absence of our outgoing Chair, John B. Morrill. We wish John a speedy convalescence from his recent surgery. The other SICB Newsletter reports cover most of our newsworthy items. Thanks to the efforts of Mark Martindale, Billie Swalla and an outstanding group of speakers, our DDCB symposium on "Evolution and Development: Patterns and Processes" was a resounding success. Mark, from the University of Chicago, deserves congratulations for organizing such a fine symposium on short notice and with a very limited budget. We look forward to its publication in American Zoologist.

The 1996 Best Student Presentation Award of $100 plus copies of at least 10 back issues of American Zoologist that have major developmental biology symposia was awarded to Julia Dallman, University of Washington, whose paper was entitled "Electrical Activity Regulates Ion Channel Expression and Contractility During Development of Muscle in Ascidian Larvae."

The next SICB Annual Meeting will be in Boston, January 3-7, 1998. (Moving to the new schedule, there will be no meeting in the 1997 calendar year because we will not meet in December.) The Division will sponsor one symposium and co-sponsor at least one more. Because our Annual Meeting will no longer coincide with the holidays, we look forward to greatly increased attendance at the meeting. It is not too early to start planning your presentations and encourage fellow faculty and graduate students to do the same. The Annual Meeting offers a unique forum at a national meeting that is large enough to be comprehensive but still small enough to be intimate. Its diversity encourages communication across specialties. In this respect, I hope that with the change in timing of the Annual Meeting one of the major obstacles both to attendance and membership will have been removed. Our Society and our Division form a meeting ground for people interested in comparative embryology, cell-developmental biology, and evolutionary developmental biology. In 1997, each member of the Division should try to recruit at least one new graduate student member, encourage a colleague to join, and prevail upon a lapsed member to rejoin the Society.

No sooner does one assume the Chair, than it is time to search for a successor. The elections for Chair-Elect are upon us. Thanks to the efforts of the Nominating Committee we have two outstanding candidates, R. Andrew Cameron, California Institute of Technology, and Scott F. Gilbert, Swarthmore College.

Remember, as the old pol said, "Vote early and vote often!"

Message from the Program Officer

Billie J. Swalla

The symposium generated much enthusiasm across the SICB membership and was well integrated.

Greetings from the DDCB Program Officer!

Thanks to all of you for your great participation in the SICB 1996 Annual Meeting in Albuquerque. A very special thanks to Mark Martindale and the speakers in his excellent symposium "Evolution of Development: Patterns and Process." All who attended were very impressed by the quality of the talks and the research presented. The symposium generated much enthusiasm across the SICB membership and was well integrated.

We would also like to sincerely thank the students and faculty who presented in the contributed papers session. In spite of being the last day, there were many excellent talks and for those of you that stuck around, there were chocolate covered espresso beans to accompany the very last talk of the meetings, Julia Dallman. Julia did an outstanding job in a tough slot and I encourage you that didn't stay for the contributed paper session to try and arrange your schedules to include them in the SICB 1998 Annual Meeting in Boston.

[Secretary's comment: I was on the judging committee, and the espresso beans had no bearing whatever on our decision on the Best Student Paper Award.]

We had less scheduling complaints this year than in the past few years and all of the Program Officers are working very hard to minimize problems in scheduling.

It may be tough to decide what to attend next year, there were a number of interesting, up-to-date symposia accepted for the meetings next year in Boston. DDCB is sponsoring two symposia to be held at the SICB 1998 Annual Meeting, January 3-7, 1998 (Click here for more details).

Message from the Secretary

Minutes of the 1996 DDCB Business Meeting

In the absence of John Morrill, who was sidelined by surgery, the Division's Chair-Elect, John Wourms called the meeting to order. One of the largest turnouts of recent years, 17 members were present, including two graduate student members.

Prior to the regular business, Stacia Sower, representing the National Science Foundation, reported that the NSF Postdoctoral Fellowship in integrative animal biology would expire in 1997, and requested input regarding the appropriate area foci should the program continue. The current focus is molecular evolution. Division members agreed that the focus should be broadened, with development and molecular systematics as one possibility. The Division thanked Dr. Sower for the opportunity to provide some input before decision making in January.

The minutes of the 1995 business meeting were approved as printed in the SICB Newsletter.

John Wourms thanked John Morrill, in absentia, for his stalwart service as DDCB Chair over the last two years and members expressed their best wishes for John Morrill's speedy and complete recovery. He also expressed DDCB's heartfelt thanks to Billie Swalla, DDCB Program Officer, for the excellent program at the meeting and for progress on excellent symposia for the SICB 1998 Annual Meeting in Boston.

He then discussed the condition of the Division. The membership has slipped to 527 (228 primary, 299 secondary affiliates), making DDCB the fourth largest division of SICB. We were once the largest. While it is possible that some members may reaffiliate as SICB asks members to declare two primary divisions, everyone should do their part to improve membership: members sponsoring students, students bringing mentors back into the fold, and the like.

Deaths were noted of several prominent DDCB members during the year: Katsuma Dan, Richard Goss, Sven Horstadius, Daniel Mazia and Jane Oppenheimer. All major contributors to the field during much of the century, and mentors to many currently active developmentalists, they will be greatly missed.

After summarizing some topics from the SICB business meeting and the Executive Committee sessions, John Wourms then pointed out that a Nominating Committee would be needed to select candidates for Chair-Elect. Hans Laufer agreed to chair the committee.

Pat Glas, DDCB's Graduate/Postdoctoral Affairs Committee Representative, reported that with the end of her term, divisional student members had been in consultation, and wished to recommend Jamie Foster, University of Hawaii, present at the business meeting, to succeed her. This recommendation was accepted enthusiastically by the membership.

Billie Swalla delivered her report as Program Officer. She was very encouraged that the symposium on comparative myogenesis for the Boston meeting was approved by SICB. In addition to this symposium, organized by Judith Venuti, the Division will co-sponsor at least one other symposium at that meeting. Jim Hanken, editor of American Zoologist promised that a strong divisional voice on symposia will be heard while final decisions on topics will include issues of publication in the journal. Billie also pointed out that ideas are needed for the SICB 1999 Annual Meeting in Denver, and that the new 18-month schedule establishes an April 1997 decision date.

Billie thanked all involved in the current symposium, and expressed special thanks to Society for Developmental Biology for providing half the support for it.

General discussion turned to the question of improving attendance at the Annual Meeting. While moving to January may provide some help, members seemed to agree that direct action by active members is needed. Also recruitment of new members is key. One suggestion was that SICB send its posters directly to an SICB member within a department rather than to the department chair. This would increase the likelihood of posting. It was also suggested that we split members into groups to contact colleagues by e-mail, or telephone to get them to send students (and themselves) to a meeting. Other recruitment suggestions would be welcomed.

In the remaining time, discussion items included what could be done to minimize the deficit at which the Annual Meeting still runs, and incentives for improving the program, which might include a separate fund for the Society-wide symposia.

1996 DDCB Best Student Paper Award

The Best Student Paper Award Judging Committee attended the several graduate student paper and poster presentations that were entered in this year's competition.

The 1996 winner is: Julia Dallman, Department of Zoology, University of Washington, "Electrical Activity Regulates Ion Channel Expression and Contractility During Development of Muscle in Ascidian Larvae."

She receives the $100 award and copies of selected back issues of American Zoologist with significant developmental symposia. Congratulations!

The Judging Committee consisted of John Wourms (Clemson), Charles Ellis (Northeastern), and Judith Venuti (Columbia P&S).

In Memory

Richard J. Goss 1925-1996

"On November 21, 1996, losing a battle against cellular growth, a phenomenon that he had spent most of his professional career studying, Richard Johnson Goss died at his home in Barrington, R.I., at the age of 71. An internationally renowned authority on growth and regeneration, Dr. Goss was known for his warm and generous personality as well as his incisive mind. His numerous scientific publications and books include the classic Principles of Regeneration (1969), still regarded as the primer for anyone entering the field. Following his retirement from Brown University, he increased his activities as an eloquent spokesman for rational inquiry in the science versus religion debate."

So begins an extended memorial note on the life of our colleague and former DDCB Chair, prepared by Charles Dinsmore who was a student of Dick Goss. This note was too extensive for the available newsletter space and is being placed on the SICB Web Site ( for those who wish to read the full text. Printed copies may be requested from Division Secretary Charles Ellis.

We extend our sympathy to his wife Marcy, their son, daughter and five grandchildren, and to his many students.

DDCB Candidates for Election

As John Wourms begins his term as Chair (1997-1998), we must elect a Chair-Elect to hold office during 1998 and to become Chair for the 1999-2000 term. The Nominating Committee, chaired by Hans Laufer has found two eminently qualified candidates who are willing to serve.

Candidates for Chair-Elect

Scott Gilbert

Current Position: Professor of Biology, Swarthmore College.

Education: B.A., Wesleyan University; M.A. (history of science); Ph.D. (biology) Johns Hopkins University.

Professional Experience: Postdoctoral work in molecular biology and in developmental immunology (University of Wisconsin); sabbatical research in Wistar Institute (pronuclear transplants in mice), Jefferson University School of Medicine (chick neurulation), and University of Helsinki (mouse kidney development).

SICB Activities: Chair of the ASZ Cell and Developmental Biology Division, 1990-1991.
