WHO WILL BE TEACHING BOTANY IN THE 1980'S - SURVIVAL OF VIABLE BOTANY PROGRAMS IN THE FACE OF DECLINING ENROLLMENTS

By Roy Saigo, University of Wisconsin-Eau Claire

Some of the demographic information related to college enrollments is grave for the future of botany. (1) The 18-year-old population is decreasing, resulting in overall lower college enrollments (Fig. 1). (2) Male students are decreasing; however, there is an increase in relative numbers of female students. (3) More older people will be returning to higher education for various reasons. Most schools report approximately 25% of their student body is composed of students older than 23. (4) There is an increase in numbers of part-time students. (5) More students are interested in disciplines with a better possibility for employment after graduation.

To answer the question of survival of viable botany programs with major decreases of 18-year-old students, the following possibilities deserve consideration:

1. Develop a comprehensive 5- and 10-year long-range plan to help your department anticipate needs and adjust to them before they happen as well as to take advantage of your strengths.

2. Evaluate the population projection for your state and school as a part of your long-range plan.

3. Find out what your college or university is doing in the recruitment of minorities and women. Discuss ways in which the sciences, and especially botany, can assist in their recruitment.

4. Discuss methods to innovatively approach the teaching of inadequately-prepared students. You will be surprised to find that approximately 30% of incoming freshmen have some weaknesses in their basic training prior to attending the University. Without assistance for correction, these students will never fulfill their potential and/or will become discouraged and join the approximately 30% of students who drop out of school prior to graduation.

5. Do you have an office of cooperative education? This support service finds cooperating businesses to provide professional positions for students during their college careers. The students must have a certain minimum grade point to qualify, and they must serve in this job full-time for approximately one semester during the school year and one summer school session. Some departments provide a certain number of credits for this experience. Approximately 90% of the students participating are hired by their particular company after graduation.

6. What are you doing, or have you done, to enhance your relationship with the high school biology teachers? Since most of our students still come from high schools, this relationship will certainly enhance the possibility of their coming to your institution. A high school botany or biology

PAGE FORTY-TWO

conference and/or workshop would help to improve communication and relationships.

7. It is important that your departmental members be made aware of the importance of faculty governance, especially during these troubled times.

8. Actively seek different approaches to fulfilling your science course requirements. Contact colleagues at other institutions for additional ideas to implement at your home institution.

9. Spend more time identifying sources of dollars to support curricular change. If your school has a person in charge of grant-writing, obtain his/her assistance. Remember that the undergraduate student is the foundation of your department, so spend a proportionate amount of time enhancing undergraduate teaching.

Who Will Be Teaching Botany in the 1980's?

The majority of teachers will be the people in the associate and early full professorial ranks. As tenure track positions will not be available, the above-categorized people will have to become, as in the early days of science, true botanists. That is, persons versed in all the basic units of this discipline. In order to achieve this level of competency, many professors will have to undergo extensive retraining efforts during the decade to come.

If your institution is fortunate and the enrollment is stable or continuing to grow, the introductory courses will be taught by temporary professors who will be hired as lecturers or visiting professors with year-to-year contracts. The danger of this system is that it leads to disillusioned teachers of little help to building the department.

In specific and unusual situations, the use of adhoc teachers will be used. These people will generally have other full-time employment, but will be hired on a per-course basis to fill in the area of need.

Which Botany Programs Will Survive Under These Conditions?

The trends in the population of our student body have been noted. Some of the suggestions to fulfill the needs of those specific groups have been elaborated. All methods of delivery must be investigated to transfer botanical information to these audiences. As in the development of a new species, those are advantaged that are fit and flexible.

BOTANICAL SOCIETY AWARDS

Citations for the Awards Presented at the 1981 Annual Dinner for All Botanists, Botanical Society of America, Inc. at Indiana University, Bloomington, Indiana, on 19 August 1981.

PAGE FORTY-THREE

Merit Awards:
These awards are made to persons judged to have made outstanding contributions to botanical science. The first awards were made in 1956 at the 50th anniversary of the Botanical Society, and one or more have been presented each year since that time. This year the Award Committee has selected two botanists who are eminently qualified to join the ranks of merit awardees.

To Clanton C. Black, Jr., University of Georgia "for his significant contributions to our knowledge of the photosynthetic process; for probing the similarities and differences in carbon metabolism in C3' C4 and CAM plants; and for seeing the immediate implications for both agriculture and ecology in new advances in photosynthetic chemistry."

To Ernest M. Gifford, Jr., University of California at Davis "for his services to The Society as Editor-in-Chief of the AmericanJournalofBotany, for contributions to botanical science as mentor of many professional botanists and as an author of a popular text, and for research that has extended the frontiers of plant development and structure."

Darbaker Prize:
This award is made for meritorious work in the study of microscopical algae. The recipient is selected by a Committee of the Botanical Society which bases its judgment primarily on papers published during the last two calendar years.

Elisabeth Gantt, Radiation Biology Laboratory, Smithsonian Institution and Alex N. Glazer, Department of Bacteriology and Immunology, University of California at Berkeley were awarded the prize "for their pioneering, imaginative investigations and detailed analyses of phycobiliprotein-containing photosynthetic antennae in diverse al gal organisms."

Isabel C. Cookson Paleobotanical Award:
Each year the Isabel C. Cookson Award is given for the best contributed paper in paleobotany or palynology presented at the annual meeting. The 1981 Award was presented to Steven Manchester from Indiana University for his paper "Fossil fruits and the history of the walnut family."

Henry Allan Gleason Award:

The Henry Allan Gleason Award of the New York Botanical Garden is given annually, from a fund established by the late Dr. Gleason, for an outstanding recent publication in the field of plant taxonomy, plant ecology, or plant geography.

This year the New York Botanical Garden awarded the prize to Drs. Howard Crum and Lewis E. Anderson for their monumental MossesofEasternNorthAmerica. This two volume, fully illustrated flora by two of the most prominent bryologists in North America is a labor of love spanning 25 years.

Jessie M. Greenman Award:

The Jessie M. Greenman Award is presented each year by the Alumni Association of the Missouri Botanical Garden. It recognizes the paper judged best in vascular plant or bryophyte systematics based on a doctoral dissertation published during the previous year. The 1981 award went to Dr. William R. Buck for his paper entitled "A generic revision of the Entodontaceae" published in the JournaloftheHattori BotanicalLaboratory 48:71-159, in 1980.

George R. Cooley Award:
The George R. Cooley Award is given annually by the American Society of Plant Taxonomists for the best paper in plant systematics presented at the annual meetings. The 1981 recipient of the Award is Gregory J. Anderson, University of Connecticut, for his paper (with David E. Symon) entitled "Sex forms in Solanum." The Award is presented for a detailed study of the breeding systems in the genus Solanum utilizing a variety of techniques including morphological characters and crossing experiments to interpret the evolution of non-hermaphroditic sex forms. Honorable mention was given to Lisa A. Standley,University of Washington, for her paper entitled "The systematics of Carex section Carex in the Pacific Northwest."

Physiological Section Award:
Each year the Physiological Section of the Botanical Society of America presents an Award for the best student paper dealing with physiology presented at the annual meeting. The 1981 Award is presented to Pete O. Council, University of North Carolina at Chapel Hill, for his paper entitled, "The control of growth in carrot cell suspension cultures."

Pteridological Section Award:

Each year the Pteridological Section presents an Award for the best paper dealing with any aspect of pteridology presented at the annual meeting. The 1981 Award (a check for $100.00) was presented to James A. Tanno, University of Connecticut, for his paper entitled "Plastid ultrastructure in Selaginella martensii forma albovariegata."

Ralph E. Alston Award:
Each year the Phytochemical Section of the Botanical Society of America presents the Ralph E. Alston Award of $100 for the best paper dealing with phytochemistry presented

BOOK REVIEWS

Mayo, O., TheTheoryofPlantBreeding, Clarendon Press, Oxford Univ. Press, New York, 1980, xiii + 293 pp.

This book by Mayo is neither a text on plant breeding nor a book on either quantitative genetics theory or population genetics theory. Instead, the author tries to cover the ground where the above topics overlap – plant breeding theory. To a large extent the chapter titles are those in a text on plant breeding, including introductory material, genotype-environment interaction, and selection response. The content stresses the theory behind plant breeding, and the theoretical questions raised by practical problems. The somewhat uneven nature of the book is probably a result of a gap between practice and theory, particularly with population genetics (as opposed to quantitative genetics) theory. Also, at times the author is extremely brief. However, the book should prove a valuable reference both to plant breeders and particularly to theoreticians looking for important, unanswered questions.

Alan Hastings, University of California, Davis

Levitt, J., ResponsesofplantstoEnvironmentalStress. Second Ed. Vol. II. Water, Radiation, Salt, and Other Stresses. Academic Press, N.Y. 1980. xiii + 606 pp. $45.00

On both theoretical and practical grounds, the ability of plants to withstand and react to the slings and arrows of outrageous environmental fortune is of increasing importance to plant scientists in many disciplines. Although there have been many research reports and several important symposium volumes on aspects of environmental stress, Prof. Levitt’s two volumes on the topic provide a consolidation and overview of the field that is otherwise unavailable. Not only are various

PAGE FORTY-EIGHT

Facets of the topic covered, but one finds a point of view and a conceptual framework that is badly needed for students and for researchers.  Although this reviewer, and others interested in environmental stress, may disagree with some of the conclusions reached by the author4, all of us are deeply in debt to him. Both this and the previous volume in the set (Chilling, Freezing and High Temperature Stress) are necessary occupants on the bookshelves of plants scientists.

Richard M. Klein, University of Vermont

Hartmann, H. T., W. J. Flocker and A. M. Kofrank. PlantScience. Growth, Development, andUtilizationofCultivatedPlants. xi + 676 pp. illust. Prentice-Hall, Inc. Englewood Cliffs, NJ 1981. $26.95.

As stated in the preface, this book was designed as a text for plant science courses "at the lower division level and in community colleges" and must be judged by this standard. Organized into three major units or sections dealing with plant structure, classification and growth, with horticultural crops and urban forest practice and with cereal, forage etc., crops, the student is exposed to a logical developmental sequence of plants and their cultivation - both theoretically and practically. It is probably a direct competitor of Janick etal. and admirably holds its own against Janick's book. Indeed, Hartmann etal. is generally a more useful book for those students who require the applied information at a more sophisticated level than can be obtained by reading the plethora of how-to books on the market, and can become better practitioners with the underpinnings that theory and fundamental botany provides.

It is a large (and expensive) volume, well illustrated with graphs, tables and photographs drawn from primary sources and each chapter ends with appropriate references and supplementary readings for use in term papers or for additional information. Review questions are included, but their value is small since they tend to be material found in the text and not questions that stimulate thinking. All-in-all, the authors have prepared an excellent, valuable and seminal book.
