Clinton Establishes Science and Technology Council
from: AIBS Washington Scene, December, 1993
On November 23, President Clinton established by executive order a new science advisory group, the National Science and Technology Council (NSTC). The NSTC re-places the Federal Coordinating Council on Science, Engineering, and Technology, and is envisioned as a coordinating body for science, space, and technology policies throughout the federal government.
The NSTC has cabinet-rank status within the Clinton administration, and the president himself will chair the council. Other members include Vice President Al Gore, presidential science advisor John Gibbons, and the secretaries of Commerce, Defense, Energy, Health and Human Services, Interior, and State. The heads of NASA, NSF, EPA, and the Office of Management and Budget are also members of the council.
The United States Department of Agriculture, however, was not included on the council. Therefore, USDA science agencies, including the Forest Service, the Agricultural Research Service, the Cooperative State Research Service, and the Soil Conservation Service, may have limited involvement in the NSTC process. Efforts to redress this omission have been initiated by AIBS and many of its member societies.
According to the presidential statement accompanying the executive order, the council will focus on broad national goals, such as information technology, rather than agency missions. The council will coordinate R&D budgets in order to accomplish national objectives in areas ranging from information technologies to health research. Co-ordinating committees include Education and Training R&D; Environment and Natural Resources Research; Fundamental Science and Engineering Research; and Health, Safety and Food R&D. On the same day, Clinton also established the President's Committee of Advisors on Science and Technology to serve as a private sector group for the president and the council. The committee's mission is to ensure that the government's science and technology policies reflect the nation's needs. Fifteen individuals from industry, education, research institutions, and other non-federal sectors will comprise the committee.

JOINT FIELD MEETING 26–30 June 1994
The 1994 joint field meeting of the Botanical Society of America, the
Torrey Botanical Club and the Philadelphia Botanical Club will be June
26-30, 1994 under the auspices of Frostburg State University, Frostburg,
Maryland. The field trips will examine plants of shale barrens, swamps,
old-growth forests, bogs and Triassic uplands. Evening programs will
deal with aspects of the the flora visited, with the geology of the region,
and with the management of the threatened species. Western Maryland
and eastern West Virginia have many interesting habitats, as well as development pressure which threatens those habitats. It should be an interesting meeting. The price is $175.00 per person. This includes housing,
meals, bus transportation, trip leadership and evening programs. For further information and a registration form, send E-MAIL to:

National Biological Survey Survives Contentious Floor Fight from: AIBS Washington Scene, December, 1993
Property rights issues dominated debate over the creation of a National Biological Survey (NBS) at the Department of the Interior on the House floor in October. Some members of Congress expressed considerable concern about federal scientists trespassing on private land to gain biological data. As a result of continued debate along this course, several amendments were added to the bill (HR 1845) to further ensure protection of the property rights of landowners, and lessen the impact of the survey. The NBS is a Department of Interior proposal to create a new agency to consolidate biological research within the department. Interior Secretary Bruce Babbitt announced his intention to establish the NBS in late March, and requested that Congress enact the proposal into law. Babbitt has the authority to establish the agency within the department, but he requested congressional consideration to put the agency into statute. The goal of the NBS is assessment of the nation's biological resources, in a manner similar to the way the US Geological Survey evaluates the nation's mineral resources. Biologists from each of Interior's agencies (e.g., Fish and Wildlife Service, Bureau of Land Management) will be transferred to the NBS to consolidate research efforts and ease jurisdictional tensions among agencies.
At times, opponents of the NBS appeared to be arguing against the acquisition of more scientific knowledge. This unsettling debate held that the more science knowledge acquired, the more precarious the situation for private property owners. AIBS, on behalf of the life sciences community, strongly objected to this reasoning, and wrote to each member of Congress that "scientific knowledge, in and of itself, will not infringe on private property rights; it will, however, provide a sound scientific base on which to determine the wisest use and management of the nation's biological resources."
Amendments adopted on the House floor included a measure to eliminate authority for the secretary to use volunteers to collect data. As an indication of the contentiousness of the debate, these volunteers were once referred to on the House floor as "environmental Gestapo." That amendment was agreed to by a 217—212 vote. Another amendment prohibits other federal agencies from using the information gathered by the survey unless the landowner was given a detailed description of the manner in which it was collected.

In his recent presidential address to the Botanical Society of America (Plant Science Bulletin 39(4):8-12, 1993) Grady L. Webster exhumes the old argument that the only way for botanists in Academe to survive and prosper is to remain totally independent in their own Department of Botany. He implies that amalgamation of botanists into any combination such as a Department of Biology guarantees a withering away of botanical strength. Like William L. Stem, to whom I responded aboutthree decades ago, Webster is partly right but mostly wrong.
The truth is that no single organizational pattern guarantees the optimal development of botany in a,~l academic settings. The best arrangement for any campus depends on many considerations, such as the nature and size of the institution, the number and quality of students and courses in botany, and the strength of relevant colleagues in related departments. Thus, the situation in a liberal arts-oriented institution, especially one without any attached school of agriculture or forestry, may dictate one course of action, while in a large state institution including many applied plant science departments, a different strategy might well be more appropriate. (For some reason, Webster refers to this rather obvious generalization as a "surprising admission".) Accordingly, I continue to believe that any attempt to force all botanists into a single organizational mold may turn out to be inappropriate or harmful to some of them.
Academic growth or even survival in these days of budgetary stringency is no simple matter, and little wisdom inheres in the adoption of stubbornly parochial or impolitic positions. Certainly some groups of botanists have been forced into integrated biology departments against their wills or because that is the only way they could survive at their particular university. That is certainly to be deplored. On the other hand, integration into Departments of Biology has sometimes helped botanists to improve their research and teaching, sometimes to an enlarged and superior student body from whom they can recruit outstanding scientists who otherwise would not have done botanical work. I believe that despite important setbacks in some areas, this has been generally true at Yale, used by both Stem and Webster as a horrible example to bolster their thesis. Webster goes so far as to refer to "the meloncholy history of botany at Yale". A look at the record of this "melancholy history" will yield a more balanced view.
First, the generally "down" side of the picture. Yale fused its Departments of Botany and Zoology into Biology in 1962. Since then the number of faculty positions assigned to botanists has declined from 9 to 7, but current searches and offers will probably soon increase that number. Fifteen botanical graduate students, twelve postdocs and a weekly seminar in Experimental Botany provide a reasonably lively and productive intellectual environment for the plant group, which specializes in genetics, development, plant molecular biology, physiology and cellular biology. Additional botanical strength is also found in certain "non-botanical" members of the Department of Biology, our sister Department of Molecular Biophysics and Biochemistry and the School of Forestry and Environmental Studies. Unhappily (and as predicted by good friend Oswald Tippo, as well as by Webster and Stem), plant anatomy, systematics, and certain other organismic studies are gone from the department, a fact that saddens the remaining botanists, and causes them to continue to press for the appointment of more classical botanists. On the other hand, plant ecology has been very strong in our flourishing (not in demise!) School of Forestry and Environmental Studies, which also offers courses in plant systematics, anatomy, pathology, soils and microbiology, while Geology and Geophysics includes a well-known paleobotanist in its distinguished paleontological group.
Now for the "up" side. One way to measure the quality of any educational program is to assess the impact of the students it has produced. In this respect the record is outstanding in one field with which lam familiar. Because Yale's Department of Biology has taught an integrated course in Developmental Biology staffed by both botanists and zoologists, its botanists have been able to co-opt several distinguished non-botanical students into re-search with plants. Among these have been Elliott Meyerowitz, now Professor at Cal Tech, whose work on the genes controlling floral development is classic, Peter Carlson, of Crop Genetics International, who first accomplished parasexual plant hybridization via fusion of protoplasts, and Gerald Fink, head of the Whitehead Institute at MIT, whose molecular genetic studies have contributed definitive information on auxin biosynthesis. Among other distinguished botanical graduates of Our department are Sharon Long, Professor at Stanford, who has revolutionized our understanding of nodulation, Virginia Walbot, also at Stanford, whose work on the plant genome has been very influential, Masaki Furuya, now retired as Professor at Tokyo University, whose laboratory was for a while the world center for studies of phytochrome, Ralph Guatrano, of the University of North Carolina, who has contributed so much to our understanding of polarity and the molecular biology of abscisic acid physiology, David Meinke of the University of Oklahoma, whose analysis of embryo-lethal mutants has greatly advanced the field, Robert E. Cook, now Director of the Arnold Arboretum at Harvard, Scott Poethig, of the University of Pennsylvania, whose analysis of clonal cell development has sparked a new under-standing of plant organization and Hector Flores of Pen State who has produced brilliant studies of plant stress and of the uses of hairy root cultures. W c have also been blessed by many able postdocs: I recall with great appreciation two influential ones of my own, both now deceased; William S. Hillman, who opened up Lenora forphotoperiodic studies, and Ruth L. Satter, who helped explain the physiology of nyctinastic leaf movements in Albizzia and Samanea. It seems tome that these people have all added to the prestige, visibility and funding of botanical research in this country. If that list constitutes a "melancholy history",I'll eat the Cycas revoluta in the greenhouse of our Marsh Botanical Gar-den.
My advice to Grady Webster is to "lighten up a bit". It is certainly commendable to fight for the rights of botanists at all universities and colleges, but in Academe, as in nature, heterogeneity or organizational pattern is a virtue. We all do what we can, in our own organizational setting, to advance our field, and each unique setting carries its own built-in strengths and weaknesses. Let us remember that not all Departments of Botany do a good job.
One final point: it is certainly a mistake to say, as Webster does, that "the molecular revolution in botany is too recent to have had a major effect in publication patterns over the past 80 years". A perusal of the size, quality and contents of such journals as Plant physiology, The Plant Cell and Plant Molecular Biology certainly leads one to the opposite conclusion.

How to Write an Influential Review
Reprinted from Pula SCIENCE BULLETIN 34(2): 5—7 (1988)
Michael L. Rosenzweig2, Jerrold I. Davis3 and James H. Browns
"It is not the critic who counts. The credit belongs to the (one) who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, and comes short again and again; who knows the great enthusiasm, the great devotions; who at the best knows in the end the triumph of high achievement, and who at the worst, at last fails while daring greatly." —Theodore Roosevelt.
Often we are asked for our anonymous written opinion of a colleague's research proposal or manuscript. Most of us respond whenever we can, because it is one of the most important ways that we contribute to the development of our science. Such peer review is the primary mechanism by which we, the community of scientists, affect the distribution of limited grant funds and journal pages. Our reviews have enormous influence on the direction and rate of progress in our disciplines.
It is not much help if we use this influence unwisely, or our review is not taken seriously. How should a review be fashioned so that it is taken at face value and not discounted? What sort of influence should it try to exert?
Surely a review should seek to identify and encourage the most promising and innovative research. Yet it is precisely the newest ideas that are the least tested, the most controversial and easiest to criticize. In fact, history reveals that new theories often are incomplete and often do contain serious errors. But wouldn't it have been a tragedy if Natural Selection had been rejected because Darwin founded it upon incorrect mechanisms of inheritance?
If we are to advance our science, it is necessary that we take risks and actively encourage the development of new concepts, theories, and methods. If we as reviewers are afraid of mistakes, and insist that our peers write airtight proposals, then who will dare to tackle the difficult questions? If we required that a proposal be so well described that we can visualize every aspect of the research, is the work really likely to produce any surprises or major new discoveries? We have to be honest and point out potential problems, but, above all, we must strive to identify and express our enthusiasm for new ideas and innovative approaches.
How do we write a review that will convince panel members and program directors that a proposal, for all its rough edges, is an eminently worthwhile risk, an exciting adventure with a high payoff if it succeeds? The Research Support Liaison Committee in Ecology, Evolution and Systematics took this question to the staff members of NSF's Division of Biotic Systems and Resources. The way we phrased it reflects a nagging perception that we shared with them: With funds scarce relative to need and the average quality of proposals very high, is there a tendency for reviewers, panel members, and program directors to be conservative, avoid risks, and look for grounds to criticize a proposal? Is any fault or loose end likely to prevent funding? Must we avoid negative comments in our reviews if we feel a proposal should he funded?
The Correlation Between Detail and Negativity in Reviews
The more negative the tenor of a review, the more detail it has. This is a fact. We know no reason why it has to be so, but it is. Negative reviews are often full of well-reasoned objections. Positive reviews are more often brief statements of approval. They may be full of glowing adjectives, but they rarely contain the details and logical arguments which would give them substance.
Faced with positive reviews lacking substance and with well-documented negative criticisms, panels are often swayed by the negative comments. What else can we expect? If NSF is to discount negative comments about promising, but risky and even somewhat flawed proposals, it must have good reasons for doing so.
Accentuate the Positive
We all know what along, negative review looks like. It is time to produce some long, positive ones. When you encounter a good proposal or manuscript, spend your time on that one. Describe in detail what makes it good. Remember that NSF panels and ad hoc reviewers are drawn from a wide spectrum of our peers. Just because we recognize the merits of a proposal does not mean that other reviewers will appreciate them. State why the problem is important, what contribution the proposed research will make, and why the investigators are well-qualified to do the work. Avoid hyperbole and be specific. Point out weaknesses, too, and explain why they have not put you off. Give the program director or editor a good excuse to follow your advice.
Many reviewers seem to think it is their primary responsibility to discover and call attention to all the flaws in a proposal or manuscript. Perhaps they have the attitude that it should be deemed worthy until proved otherwise. They may sound fair, but it is, in truth, pernicious. It makes us over into petty bookkeepers, subtracting the value of each counterfeit penny without noticing that they arc coming from a solid gold box. If we adopt the attitude that a proposal does not deserve funding unless the research is daring, novel or interesting, then we should place more emphasis on the positive aspects of a good proposal and write longer, more constructive positive reviews.
We need to remember that it is much more damaging to our discipline to suppress an important contribution than to fund or publish a questionable piece of research. New ideas and conflicting data cannot have any influence unless they are developed, whereas serious errors will usually be detected and corrected, either by the investigator before publication or by the scientific community soon afterward. This is why it is essential to be broad-minded, and to consider the potential importance of a piece of research as well as to search for flaws.
Regulate the Proportion of Positive Comments
Do not undermine what is intended to be a positive_ review by devoting more attention to criticism than to supporting comments. The overall impression your re-view makes depends upon the proportion of criticisms which are positive. You cannot counter that fact with an introductory or concluding paragraph. If there are three pages of negatives, and the first sentence says, "This is a manifestly important proposal and should be fully funded," what do you think the panelists notice? Their overall negative impression cannot be reversed. Believe it. If you really think the proposal is that good, fill the review with your reasons and mention the negatives briefly.
The score assigned by reviewers to NSF proposals is also very influential. As much as panel members and program officers try to read the reviews carefully, it is a fact that proposals that receive low scores or average less than "very good" have a difficult time. Scores should reflect the priority that we place on supporting a particular program of research, not the number of nita that can be picked from the way the proposal is written. In writing a review we would all do well to bear in mind the difficulties we each have in writing a proposal to support the most exciting of our own research.
If you feel compelled to note every flaw, send the details directly to the author, and point out in your review that you have done so. The panel will then be even more convinced of your positive opinion because they see you are taking so much time to help. For example, a prescient reviewer of Darwin might have written, "I have my doubts as to the validity of Mr. Darwin's ideas on the process of heredity, and I have written to him in detail about these doubts. But even if I am correct, Mr. Dar-win's proposal to visit the Galapagos Islands remains extremely valuable." And just to be sure that you realize Darwin is hardly the only example, consider whether it would have been wise to discourage R.A. Fisher's re-searches because his models lacked the component of genetic drift. Would you have suppressed Eldredge and Gould's work on punctuated equilibria because they first insisted that punctuation had to be connected to speciation? Would you have retired R.H. MacArthur as soon as he made the illogical jump from resource-use overlaps to competitive alphas?
Simultaneously, we should learn to write shorter negative reviews. Simply admit that you found nothing particularly exciting or novel. It is very important, however, to write such reviews, thus calling attention to proposals that are solid but unexciting and unlikely to result in significant advances. If other reviewers have expressed similar concerns, the panel will have little difficulty making an evaluation. The panel needs help ensuring that critically short funds are not wasted on pedestrian projects.
The above is not intended to suggest that we should endeavor to be less critical. Serious criticisms and substantial concerns should always be expressed, but this can be done in dispassionate language without indulging in ad hominem assaults.
Critics of art and literature, whose criticisms are often published and who earn their keep from them, feel they must entertain their readers with a rapier wit, caustic comments, piercing put-downs, and acid cuts. Many appear to have decided that criticism is a written version of prize fighting, except that in boxing, low blows are against the rules. Leon Wieseltier calls it "aggression as an intellectual instrument".5
Unfortunately, all too many negative scientific re-views seem to have been written by put-down artists. This is not only cruel and cowardly (at least the literary critic signs his piece), but it minimizes their influence as well. The editor, panelist or program director is driven to sympathize with the victim. This may mean that if you and you alone noticed the flaws, but reported them intemperately, your criticism will be ignored. Moreover, such aggressive attacks leave a lasting impression of unprofessionalism on your part.
The Payoff to our Whole Science
Basic science in America is often under attack as a social luxury, and an expensive one at that. Usually the attacks are oblique. Politicians ask what direct, immediate benefits to expect from our work, or given golden fleece awards to projects whose titles make them easy targets.
Dr. Janet V. Dorigan of the Department of Energy has observed that when scientists are under attack, they circle `round, wagon train style. The physicists aim outward at their opponents. Biologists, on the other hand, aim inward, at each other. Their weapons, of course, are disparaging reviews and negative comments.
The earth pulses with fascinating ecological and evolutionary questions, and threatens with environmental concerns. The questions are as intellectually challenging as those facing any other scientific discipline. The answers are essential to deal with the environmental problems that best the world. But we cannot convince other scientists (or the public, or government officials) of the importance of our work if we seem to be calling each other incompetents. Why should anyone want to invest in a bunch of incompetents?
In order to convey a more accurate impression of the view of our collective labors, we all need to make a conscious effort to tolerate diverse ideas and unconventional approaches, and to promote independence and originality. Robert Reich has written that "Technological innovation is largely a process of imagining radical alternatives to what is currently accepted." In our reviews, we must encourage that dissent and emphasize the advances it will make possible.
A famous cartoon character (Pogo) once said, "We have met the enemy and he is us." This may accurately characterize many human activities, such as ethnic and religious prejudice, war, and degradation of the environment. But it cannot be permitted to be true of the scientific enterprise, which is, in its very essence, mutuālistic and collaborative. The peer review system has obvious limitations and imperfections, but it is the best means that scientists have devised to evaluate each others' work. It is up to us, the community of ecologists, evolutionists and systematists, to use the peer review system carefully and wisely. One then can make it serve the goal we all share: the rapid advancement of our disciplines.

With sorrow we announce the death on Jan. 14, 1994, of Joseph Miller Wood, age 72, Professor Emeritus of Biological Sciences at the University of Missouri. Joe came to Missouri in 1960 after completeing his PhD in botany at Indiana University. He regularaly taught Botany to an audience of more than 500 students, and was considered "a master with a piece of chalk." He was one of the first recipients of the Standard Oil Teaching Award, and also received the Teaching Award of Merit of the Gamma Sigma Delta Honor Society and the coveted MU Arts and Science Student Government Purple Chalk Award. Joe maintained an active research program in paleobotany, training seven PhD and two MA students. He was appointed Professor Emeritus in 1985, at which time he donated his extensive pollen slide and specimen collection to the MU Herbarium (UMO).—Robin Kennedy, University of Missouri

The Molecular Biology of Flowering B.R.Jordan, ed. 1993. ISBN 0-85198-723-0 (cloth US$85.50; UK£45.00) C.A.B. International, Wallingford, Oxon OX10 8DE, UK—"Flowering is a fundamental process in plant development", the Preface of this expensive little tome begins. Well, "Call me Ishmael!" I said to myself. Things soon looked up, however: The Preface promised a set of reviews, each of which "provides a framework of existing knowledge into which future information can be incorporated." And then it promised two introductory chapters "that establish the context of the molecular research." Now this could be my kind of book, I thought. While there is at least one excellent chapter in this book (unfortunately, a xerographic copy won't do justice to the color plate), I found the rest of the book to fall quite short of the rather lofty aims in the Preface. Eternal optimist that I am, I hoped that the first chapter would point out that flowering was an angiosperm-specific example of a widespread and more general property. From the algae on up (ignoring similar phenomena in animals), plants perceive their environment, and, often when times get bad or nutrients start to dry up, development switches from ordinary vegetative growth to the production of some kind of propagule, vegetative or otherwise. And, since you know that photoperiodism is going to rear its ugly head later in the book, I was ready to read about appropriately primitive floras, their latitude and longitude, and get the current scoop on whether photoperiodism is primitive or derived. Perhaps, since all that long-day, short-day, vernalization stuff continues to fascinate plant physiologists, the introductory chapters might speculate at least on whether such responses are variations on one theme or some exercise in counterpoint. I'd learn a lot; I'd be able to mine it for lecture material.
The first chapters do make for nice reading, but are so restricted in scope they seem most suited to remind you (a seasoned professional) of what you already know. For me there was a sprinkling of incidental facts and nuggets—did you know that water stress has little or no effect on flowering in sunflower, for example? No reference given, so you'll have to test it yourself, write the author, or browse through a data-base if you want to know more. Even the stuff I found myself disagreeing with was sufficiently superficial that I couldn't really object—like the part about plants being made up of phytomers, and sentences like "Defoliation experiments indicate the rate at which the stimulus moves." I think I'll continue to haul out the Wareing and Phillips for the undergraduates, use things like Carl McDaniel's re-views to jog my own thinking, and hope that Richard Greyson's new book may be what I seek. It really would be nice to have what the Preface promised: a rigorous context to introduce and focus the contemporary molecular work on flowering.
The next chapters re-review the first chapters (and it is interesting to see how each set of authors picks and
chooses) and then review gene cloning and genes cloned by gene cloning (covering and recovering the same ground, once again showing interesting variation in the views of the sets of authors). There are no "frameworks" for incorporating future information here, gentle reader. There are some good tables with the various names for the same gene isolated by different people in the same organism, or the homologous genes isolated by other people in other organisms: a kind of floral molecular concordance, and certainly useful. In general, these chapters will go out of date quickly—witness the papers on Arabidopsis flowers and inflorescences in recent issues of SCIENCE and PLANTA. There is at Ieast one glorious typo: a Figure on page 55 where Genotype and Environment are coded "+" and "–" and presented four times as interacting in the same pattern with the same end results, while the fascinating but incomprehensible section of the text begins "The last of these patterns of effect describes the situation where the genotypic difference is not influenced at all by the environment." The authors of this chapter are smart folks, and I really wish I could decipher their page about genes for time-to-flower and how they might act.
The final two chapters, a brief look at fertilization by Dumas and Gaude, and a succinct summary of floral pigmentation by Martin and Gerats, come close to the promise in the preface. Neither is encyclopedic, and there are typos or out-and-out mistakes (unless some Authority has transferred Camellia japonica to the mono-cotyledons). Maybe I'm just a sucker for papers that cite
"Mendel, G. (1865) VERHANDLUNGEN DES NATURFORSCIIENDEN VEREINS IN BRCTNN IV:3-47" with such authority that I am convinced that the writers actually read it in the original and not in the Stem and Sherwood translation. These chapters summarize results by giving the actual finding (and then the reference). The subsections usually end with a speculation or suggestion of what is likely to be exciting soon, conveying a sense of movement and scientific progress—a marked contrast to the suggestions elsewhere in the book that accumulating enough genes and sequences will eventually lead to deeper (or real) understanding of the flowering process.
This is one book that your librarian should get only by interlibrary loan.—Michael Christianson, University of Kansas, Lawrence
Forest Development in Cold Climates NATO ASI series A: Vol. 244. J. Alden and S. 0dum, eds. 1993. ISBN 0-306-44480-1 (cloth US$135.00) Plenum Publ. Corp., 233 Spring St., New York NY 10013—At first glance Forest Development in Cold Climates appears to be the right book for the wrong reason; an extensive compendium of papers on silviculture, tree developmental morphology and physiology, biogeography, genetics, and forest history —with the singular intent of improving forest productivity at high latitudes for commercial use. A second look at the book, tempered with a forward by President V. Finnbogadōttir of Iceland (where this NATO symposium was held in 1991) introduces the humanistic importance of trees and forests, especially for people in nearly treeless high latitudes. The president ends her address on a note of hope which acts, unfortunately, as the major unifying theme in this large (566 pp) volume. There is little else to direct the collection, save a disappointing four-page summary of working group sessions toward the back of the book. Questions brought up in early papers, such as the desirability of introducing exotic species to delicate ecosystems, forestry vs. agriculture, and the role of afforestation in reclaimining degraded ecosystems, all go unexplored. If there is a theme in this book, it is the then-presumed inevitable advance of global warming and its projected effects on cold-climate forestry. Tragically, the here-and-now consequences of severe over-utilization of forests in marginal areas, for example northwestern North America, are ignored. The topic of environmental abuse through clearcutting might have been too controversial at a NATO meeting in 1991, given the policies of the Reagan-Bush era, but it would have provided a stronger basis for action than the hypothetical scenario of global warming that is repeated throughout this book.
Within its narrow scope the book makes a scientific contribution. The papers strike a balance among disciplines. Readers are introduced to topics atmolecular and cellular levels, and larger-scale studies are also included. The inclusion of Webb and Harwood's paper on PlioceneNothofagus forests provides abalance from the perspective of historical biogeography. Trees as organ-isms are not neglected, which helps to make the book accessible to non-specialists who may be interested in a range of issues. However, they are viewed as organisms in a biotic vacuum. The scope of the book is too narrow because it portrays trees as living systems at their functional limit as defined by climate. Much of the book seems to address trees as a problem in engineering: models are introduced, discussed, and applied, but some-thing is missing. The interactions of trees with other organisms is somehow overlooked. Yet interactions would seem to be of great importance in marginal climates since the stresses on biological systems are so great. For example, fungal and animal pathogens, the role of birds and small mammals in seed dispersal and consumption, and the effect of lichens and bryophytes as inhibitors of seedling establishment are not reported. Mycorrhizal relationships, which are potentially of major importance to tree survival in cold climates, are briefly mentioned in only three of the papers but are not discussed in depth anywhere.
It is curious that the papers focus on treeline, which is the most marginal of cold-climate forest habitats. Taiga, wetlands, bogs, and sinkholes, all of which are marginal and which may be considered cold-climate in some contexts, are not treated. These habitats occupy vast areas of the earth's surface and from an afforestation perspective they are perhaps more practical than the
coldest climates. Marginal forests have been variously utilized by humans for millenia, and they are closer to centers of human population (and more threatened by humans!) than are high arctic areas. Why have they been ignored here?
A strong point of the book is that exhaustive references are provided by the contributing authors. I was introduced to research I was not aware of in areas of interest (for example, the horticultural uses of Salix) through the contributed papers and their literature citations. The papers themselves might have benefited from a bit of pruning. This would have made the book more managable in terms of size and cost, and would have reduced some of the repetitious material. The obvious expense and technical expertise that were devoted to the volume are belied by its incomplete subject index. Forest Development in Cold Climates is a useful albeit narrow reference book with some excellent contributions. It brings a variety of disciplines together through its contributed papers, which may be useful for some readers. Its focus on the biotic-abiotic interface of trees with the most marginal cold climates is just too narrow a scope to make this book a must for every library.—Samuel Hammer, Boston University
Functional Ecology of Woodlands and Forests. Packham, J. R., D. J. L. Harding, G. M. Hilton, R. A. Stuttard. 1992. Chapman and Hall, London. 408 pp. ISBN 0-412-44390-2 (cloth), ISBN 0-412-44390-6 (paper)—There has been a recent upsurge in student interest in both ecology and a wide range of issues related to woodlands and forests. Accordingly, the publication of this text is timely. The book, which is a completely renovated edition of Ecology of Woodland Processes (Packham, J. R. and D. J. L. Harding. 1982. Chapman and Hall, London), is written as a standard undergraduate text in forest-woodland ecology. The layout, printing, and figures in the book are excellent, and I could find only three typos in the entire text.
The book is divided into eleven chapters. An introductory chapter reviews the ecology of individual trees, spatial and temporal organization of forest-woodland communities, ecosystem components, tropical forests, biomes, forest threats, and silviculture. Chapters 2 and 3 focus on plant adaptations, including sections on physiological ecology, phenology, life forms, and basic strategies of germination, establishment, growth, andreproduction. Chapter 4 covers soils, plant-soil interactions, community zonation over the landscape (latitude, longitude, and altitude), and a section on sources of diversity within communities. In Chapter 5, on "Forest Change," the authors present succession, the mosaic theory, patch dynamics, the Krakatau case study, paleoecology of British woods, and coppicing systems. Chapters 6-8 provide broad coverage of the autecology and strategies of herbivores, pathogens, carnivores, and decomposers, as well as information on key-factor analysis, ecological strategies (r- and k-selection), and sources of gradients in diversity within communities (e.g. latitudinal gradients). This overview of these functional groups of organ-isms provides the background for Chapter 9, which reviews energy flow and nutrient cycling through these trophic levels. Chapter 10 and Chapter 11 are each a collection of topics related to "Working forests" (forest management, forest genetics, fire, and agroforestry) and "Contemporary problems and the future of forests" (desertification, climate change, acid rain, arboriculture, farm forestry, and habitat restoration), respectively.
One of the strengths of this book is its broad coverage, much broader than most other forest ecology textbooks, such as Forest Ecosystems (Waring, R. H. and W. H. Schlesinger. 1991.340 pp. Academic Press, Inc., Orlando, FL), Terrestrial Ecosystems (Aber, J. D. and J. M.Melillo. 1992.427 pp. Saunders College Publishing, Philadelphia, PA), and Forest Ecology (Spurr, S. H. and B. V. Barnes. 1980. 3rd ed. Wiley, New York). Packham et al. broach almost every subject related to forests and woodlands, including the autecology of a very wide range of plant, animal, and other species; interactions of plants with other organisms; community ecology; vegetation science; soil science and ecology; ecosystem ecology; conservation issues; arboriculture; forest management; and silviculture. There is more plant autecology and more applied ecology in this book than in those listed above and other similar books. In fact, the text could be described as a merger of texts on plant autecology, forest ecosystems, and forestry. The advantage of this approach is that is exposes students, such as lower-level undergraduates, to a smorgasbord of topics related to ecology and forests, some of which they may wish to pursue in more advanced courses or for a career.
Clearly, the greatest strength of the book is its richness of examples, case studies, and natural history details. For almost every general point, specific species or systems are presented in some detail. The strength of this approach shines through in the context of ecosystem ecology. Energy flow and nutrient cycling often are presented in textbooks in what students might call a "dry" manner, devoid of the excitement of real organisms. Chapter 9 presents this important information, but Chapters 6, 7, and 8 do an excellent job of setting the context for this material in terms of the examples, basic strategies, and effects on live and dead plants of the species that actually fill the "black boxes" used in Chapter 9. Chapter 3 on "Reproductive Strategies of Woodland Plants" also provides an impressive variety and depth of examples and natural history. Refreshingly, many of the examples in the book are from the authors' own studies and experiences, and these cases are conveyed with the depth possible only with such inside knowledge.
The approach of the book—broad reportage and emphasis on case studies and examples—may constrain the usefulness of the book for some audiences. The broad coverage appears to result in uneven treatment of topics. For example, although there are six pages on masting in
trees, there is relatively little on germination. There are eight pages on coppicing, mainly in Britain, but only one or two paragraphs each on diversity and stability and on global climate change. Such sections should, perhaps, be deleted or elaborated in future editions. In general, owing to its breadth, a book of this sort can not present the depth that some teachers may seek.
The richness of examples in the text appears to be at a cost of emphasis on general principles and themes; for some, the book may read more like a compilation than a synthesis, especially compared to similar textbooks. This approach may, in part, reflect a more system-oriented as opposed to a concept-oriented philosophy, which is suggested in the text as follows: " ... the quest to find a unifying theory of succession is a pointless one. On the other hand, an understanding of how succession operates in particular habitats is of great value to vegetation managers ... " (p. 141). This emphasis also appears to result in some lack of clarity in organization. For example, seed dormancy is in a section in Chapter 3 on seasonal changes in communities rather than with other aspects of reproductive strategies earlier in the chapter. A section on diversity within communities seems very out-of-place in Chapter 4 on "Soil, Climate, and Zonation"; in fact, factors controlling diversity are scattered among Chapters 4, 5, and 7. Combining these sections would clarify and emphasize this crucial topic. In other chapters (e.g. 7 and 10), it is similarly difficult to detect a conceptual thread. The challenge of this type of book is to provide students with a feeling for the complexity and excitement of nature, while conveying generalizations in concepts, approaches, and contexts—no easy task. The text achieves the first goal with flying colors, but, for some teachers, this book may have inordinately sacrificed attention to general principles in the process.
Although the range of concepts and examples in this book is international, the authors emphasize Britain, British ecological perspective, and temperate zone forests. Much attention is devoted to some concepts (e.g. phytosociology, British consery ation science) and methods (e.g. coppicing) that are much more relevant to British and European ecologists than to North American or tropical ecologists. Other topics (e.g. fire ecology, conservation biology, gradient analysis) of stronger relevance to North America and the tropics receive little coverage. A large portion of the examples, especially the detailed ones, are from Britain and from the temperate zone.
This book is an excellent choice for lower-level (or non-majors) forest ecology courses in which teachers seek breadth of treatment, solid knowledge of British systems, but also an international scope. For upper-division courses, texts with a more narrow focus, more emphasis on principles, and more references (e.g. Waring and Schlesinger 1985) may be more appropriate. For North American teachers and courses, the book would probably not be satisfactory. Other course texts, with more emphasis on North America, such as the three mentioned in this review, would make better choices.—Drew Barton
Nature's Champion. B. W. Wells, Tar Heel Ecologist James R. Troyer. 1993. ISBN 0-8078-2081-4, 243 pp. (cloth US$24.95). University of North Carolina Press, Post Office Box 2288, Chapel Hill, North Carolina 27515-2288.-Ecology is becoming more and more aware of its history. Over the last several years, a number of books have appeared that outline the development of the science, as well as a selection of biographies of ecologists that serve to flesh out the skeleton. Book-length works about Victor Ernest Shelford, Forrest Shreve, Aldo Leopold, and John Thomas Curtis are recent examples. Troyer has now given us a biography of Bertram Whittier Wells, another of the "old timers" that helped to build ecology into its current position in the community of sciences.
The book consists of 14 chapters organized into four parts; Scientist, Champion of Nature, Academician, and Private Person, plus a short Prologue and an even shorter Epilogue. Wells spent most of his professional career in North Carolina, starting in the early days of what was to become North Carolina State University in Raleigh. He was trained at Ohio State, and finished his PhD at the University of Chicago in 1917. After a couple of temporary positions, he began his career at North Carolina State in 1919 as head of the Department of Botany and Plant Pathology. The other two faculty members were both pathologists, so it fell to Wells to handle all of the botany courses. Not unusual for that time, conditions were primitive, equipment almost nonexistent, and library facilities in short supply. Apparently, Wells was
most concerned, however, with the lack of "academic excellence," and throughout his career, he tried to raise the standards of the institution. By linking teaching and research, by upgrading the curriculum, by proposing that the College begin a program in Forestry, Wells sought to elevate the intellectual atmosphere. Reviewing North Carolina State University today, success in this venture is evident.
Wells was a good teacher, as exemplified by his classroom and laboratory skills, his eminence as a field trip leader, and the tremendous amount of time he spent in public lectures and semipopular writing. In research, he was oriented primarily to the Carolina Coastal Plain, with apparently little interest in either the Piedmont or the Mountains, although class trips were sometimes taken to these regions. His research was sometimes ignored, sometimes denigrated, particularly by those with whom he was often in direct competition. Ecologists at Duke and elsewhere took issue with his work on the origin of the Carolina Bays, resulting in Wells working (perhaps) in somewhat of a professional vacuum.
In addition, Wells did not have many graduate students, producing only one PhD in over thirty years. In contrast to many contemporaries, even those in close proximity, one is left to wonder at the potential reasons. What comes through in the biography is a private person of quick temper, constantly reminded of his lack of respect by his peers—almost a Rodney Dangerfield syndrome. There is little information on his activity in the research arena that might have led to greater fortune. He loved the Big Savannah, and left his mark with good work on southeastern plant communities, from the Carolina Bays to the Appalachian Grass Balds. His published scientific works in ecology range from ten cited abstracts and three by "title only," to many contributions to the Journal of the Elisha Mitchell Scientific Society. To be sure, Wells published in Ecology, Ecological Mono-graphs, and the Botanical Review too, but his research record, by many standards, is still sparse.
Nevertheless, Troyer has presented an admirable biography of a quite remarkable man. Virtually all that one looks for in a work such as this is present, although one wishes for a bit more integration and less apologia. The parts on "Scientist" and "Academician" are, in my view, inseparable, and I believe both would have been strengthened in combination. Some of the writing is difficult at times, with introductory clauses straining the precepts of good grammatical construction and syntax. My main problems with what is otherwise a most engaging story lie with the citation style. Whole paragraphs are covered by a single footnote. Pages 199-213 carry "Notes" for each chapter. Many of these refer to archival sources (e. g., Wells papers, Whitford papers, etc.), while others are bibliographical references by author and date. The Bibliography (pp. 215-231) is sectionalized. Section I., Unpublished Sources, is followed by H., Published Writings of B. W. Wells, and III., Other Published Sources. Section II has six parts, A. Reports of Research in Ecology, B. Reports of Research on Insect Galls, C. Miscellaneous Scientific Reports, D. Other Communications to Scientists, E. Works Related to Teaching, and F. Popular or Semipopular Works. Working from text to footnotes to citations, I kept wishing for a simple, unified, chronological bibliography of the writings of B. W. Wells.
At times the author goes to great lengths to make the writing conform to the endnotes. On page 194, for example, "... in 1986 the botanical community was provided with a detailed study of his ecological work." Getting to the end of the long paragraph yields note 11, which among other references, cites Troyer 1986, a reference to a paper published in the AMERICAN JOURNAL OF BOTANY by the current book's author. While cognizant that this is a matter of personal preference, I wish that "(Troyer 1986)" simply appeared in the text. After much back and forth searching, the frustration level climbs precipitously.
Several redundancies could have been eliminated. We are told several times of "his book, The Natural Gardens of North Carolina," and are twice informed (p. 175 and p. 191) that he referred to himself as "a gifted amateur artist. Wells' second wife, Maude Rhodes Barnes, is repeatedly referred to as "Barnes." In Chapter 14, she becomes "Maude," but we are left to wonder what B. W. called her!
The book is nicely printed and bound, and is remark-ably free of error. It is liberally sprinkled with photo-graphs of Wells, spanning his lifetime, and showing him in laboratory, field, and office. His retirement photo (p. 148) is of an impressive gentleman, whose pose and mien almost seem to summarize the set of chapters in Troyer's biography.
As the life and times of one of America's early ecologists, the book is a welcome addition to the biographical and historical literature of the science. If widely read, it will serve to remind many contemporary ecologists of what conditions were like before the National Science Foundation. North Carolina State University, the State of North Carolina, and the entire south-eastern United States are enriched by its publication, and I have only drawn attention to minor blernishes in what otherwise is an important and scholarly work on an exemplary, but little known, ecologist.—Robert L. Burgess,SUNY, Syracuse plant will be locally managed.
The potential for using ecotourism as a means of integrating conservation and development is addressed by William Weber in one of the case studies dealing with fisheries and wildlife. Focusing on primate conservation in Africa, Weber reports how the combination of foreign revenue and local employment associated with the Rwandan mountain gorilla project has resulted in increased protection for this endangered species. One of the most important aspects of ecotourism revenues is in changing how local residents and government agencies view the value of conservation. Serious constraints to ecotourism, however, exist. Besides being dependent on political stability, ecotourism is limited by the number of charismatic, easily viewed species that visitors are willing to pay relatively large fees to "experience." Further-more, areas of greatest biodiversity may not coincide with those of target species.
While Perspective on Biodiversity focuses on the relationship between development and conservation, it is not limited to low latitudes. Wilcove and Olson quickly point out that this issue in the Pacific northwest of the United States is not one of owls vs. jobs, but a complex debate over valuing goods and services from forest ecosystems. They too emphasize the importance of in situ conservation in maintaining the "content and con-text" of diversity. They point out that we have little information of the impacts of development on genetic diversity because such data are difficult and expensive to obtain. One of my surprises in reading this book was how little genetic resources have been directly assessed. This may reflect technological limitations for inexpensive, rapid through-put methods for genetic appraisal. It may, however, indicate the critical state of conservation world-wide for which the absence of such information is not a major limitation.
Throughout the book the importance of local contribution to and benefits from conservation efforts is emphasized. In their chapter on "Community and govern-mental experiences protecting biodiversity in the lowland Peruvian Amazon," Pinedo-Vasques and Padoch contrast the current state of the Pacaya-Samiria national reserve with the Mahuizococha intervillage reserve. The management of the former occurs at the national level and is directed by a team of specialists; the latter depends exclusively on an intervillage committee and is not formally recognized by the Peruvian government as a conservation area. Both seek to preserve biodiversity in the face of increasing pressure by commercial extractors. In the former all resource extraction is prohibited, in the latter hunting, fishing, and collecting forest products are permitted in specific areas. Mahuizococha provides most of the fish and game meat consumed in three villages; Pacaya-Samira supplies urban areas of the Peruvian Amazon with nearly all of their fish and game meat. This points out both the importance of local involvement for protecting resources and the need to coordinate conservation programs with regionwide planning to ensure that urban communities have access to
Perspectives on Biodiversity: Case Studies of Genetic Resource Conservation and Development C. S. Potter, J. I. Cohen & D. Janczewski, eds. 1993. ISBN 0-87168-512-4, 245 pp (no price given). AAAS Press, 1333 H Street, NW, Washington, DC 20005, USA—What is biodiversity? Is it important, and if so, important to what? How much is a species worth? What is the value of a given species to human society? Should conservation strategies be scientifically or culturally based? Why should we care?
A central premise of this collection of essays is that conservation of biodiversity enhances the potential for economic development, whereas loss of genes, species and ecosystems reduces options for transforming society. Thus, conservation of biotic resources—whether they be housed in communities or chromosomes—requires that the socioeconomic context be examined. Yet, while the consideration and involvement of local factors is essential in promoting both conservation and sustain-able development, it is not enough. Ultimately, population, poverty, political instability, and economic policies that promote export-driven resource exploitation under-lie the environmental, cultural, and genetic erosion that form the hallmark of the 20th century.
Perspectives inBiodiversity addresses the importance and implementation of genetic resource conservation. The book itself can be divided into two parts. The first consists of four essays (three of which are reprinted from Science) that explore broad conceptual issues surrounding conservation; the second documents specific examples of resource conservation. This latter part is, in turn, broken into four sections (of three chapters each) covering agroccosystcms, fisheries and wildlife, managed forest ecosystems, and regional development. A common theme running through these "case studies" is that they occur within the context of international development and, thus, highlight the competing interests and often antagonistic relationships between the various stakeholders. It should come as no surprise that it is these case studies that form the most engaging portion of the book. This is not to imply that the opening chapters are neither instructive nor unimportant. Yet, perhaps as in poetry, it is through specific experiences and details that a more universal understanding is achieved.
Or maybe we just like reading about Carlos Pinto's farm. In the first of the case studies sections, Garrison Wilkes documents a recent trip (1991) to visit all of the known sites of teosintc populations in Guatemala. Drawing upon 30 years of experience with maize relatives, Wilkes documents not only a dramatic decline in teosinte populations, but also his interactions with co-workers and government officials. His travels emphasize that genetic resources most important for crop species often occur in weedy zones associated with cultivated areas, rather than sites of intrinsically high diversity. Thus the importance of fallow areas on Carlos Pinto's farm. Wilkes also reports a Guatemalan initiative to financially encourage farmers to protect and preserve teosinte populations. This represents the first time that in situ conservation of an annual wild relative of a major crop adequate resources.
How do we value good vs. goods? Ethics vs. economics? The issues are complex; the options irrevocably closing. As Morowitz points out in his chapter entitled "Balancing species preservation and economic considerations," there has been far too little dialogue between economist and environmental biologists. Perspectives in Biodiversity presents an invitation and a confirmation that addressing specific situations, rather than searching for broad principles, that natural resources are actually conserved.—N.M.

Crop Evolution, Adaptation and Yield L.T. Evans. 1993. ISBN 0-521-22571-X (cloth US$95.00) Cam-bridge University Press, 40 West 20th St., New York NY 10011-4211—This is an amazing book. The subject is crop plants, their domestication, evolution through migration and adaptation to evolving pest and pathogens, new soils and water regimes, changes in daylength, seasons and cultivator practices. Them ark of success for almost all crop plants has been measured by yield. The ultimate test of a "good crop" has usually been yield over cost of inputs (labor, land, water, fertilizers, seed, etc.). The book is unlike any other I've ever read in the area of cultivated plants, the coverage is both wide ranging and unique, totally fresh views are taken in every chapter with the author putting his personal experiences and insights on every page. The book is a true rambling of genius through all the elements that make crop plants so highly productive and that influence yield both positively and negatively.
The book is organized in eight chapters that group in three mega-sections. The first three chapters take a quarter of the book and cover the role of crop plants in feeding the world, regional differences and domestication histories of the classic Vavilov centers. This section is not a rehash of the familiar but full of novel ideas and new emphases. The next three chapters cover half of the book and look at the ecology of yield, physiological aspects of crop improvement and trends, and limits to yield increase. The first six chapters are a backdrop to understanding the last two chapters, on inputs, the efficient use of resources, and the future of yield.
The book is a personal synthesis of the author which is well documented with original figures to illustrate the text and almost a hundred pages of references. The author truly breaks new ground and has created a whole new way to look at crop plant evolution and improvement. The coverage is expansive, with many tropical crops used as examples, but the style is not encyclopedic in the sense of exhaustive or complete coverage in a systematic way of all that is known about yield. The value of the book is the breadth of new ways of looking at familiar topics. Stereotypic coverage of the familiar is totally lacking and for those that enjoy new and piquant ideas the book is pure pleasure. Some of the views and interpretations might not be true or hold up under scrutiny of detailed examination but they are certainly mind expanding.
To truly appreciate the work requires an extensive knowledge of crops, the agricultural context of production and classic plant physiology. Sometimes the author jumps too fast without leading the reader carefully through the literature to follow the flow of ideas. Since this book is like no other and should be read by all involved in international agricultural development to feed an expanding human population, I do hope there will be a second and expanded edition in the future. This book marks the threshold of a new way to view crop improvement and both the Cambridge University Press and the author should be congratulated for a brave step forward and beyond the maddening crowd's "same and safe" writing. In my view the author is in the company of DeCandolle and Vavilov in the new insights he brings to cultivated plants. Bravo!—Garrison Wilkes, University of Massachusetts, Boston
Origin and Geography of Cultivated Plants N.I. Vavilov. 1992. [ed., V.F. Dorofeyev]. English Translation, D. Lave. xxxi + 498 pp. ISBN 0-521-40427-4 (cloth US$120)Cambridge University Press, 40 West 20th St., New York, N.Y. 10011-4211. —This collection of papers written by Nikol ay Ivanovich Vavilov on the geographic origins of cultivated plants was originally published in Russian in 1987 by the Soviet Academy of Sciences to commemorate the 100th anniversary of his birth. It is one of several volumes of his works published for this celebration. The 1992 English language edition was made possible by a cooperative agreement between the Russian N.I. Vavilov Institute of Plant Industry (VIR) and the United States Department of Agriculture (USDA-ARS).
Students of agriculture are well aware of the contributions of Vavilov who in the tradition of Darwin essentially created the modern discipline of crop evolution. During his tenure as director of the VIR from 1921 until his arrest in 1940, Vavilov pioneered the discipline of genetic resource management and created an infrastructure for cultivated plant exploration, germplasm collection and evaluation, and modern plant breeding pro-grams which became an example for the rest of the world. Ironically, this man who contributed so significantly to the Soviet effort to reorganize its agricultural system died of starvation in the Saratov prison in 1943. Although his voice was silenced by the collaboration of the Stalinist system with the political goals of T. D. Lysenko, Vavilov's strong influence on the scientific commitment of his colleagues persisted. In the Preface, V.F. Dorofeyev and A.A. Filatenko document the further development of the centers of origin theory by Vavilov's colleagues, noting that it continues to serve as the fundamental basis for Russian plant breeding pro-grams.
Most Westerners are only familiar with Vavilov's first major article published in Russian in 1926, "Center of Origin of Cultivated Plants" (pp. 22-135), and a 1935 article published posthumously in English [CHRON. BOT. 13 (1-6): 14-54, 1950]. In the initial introduction of his theory, Vavilov proposed five centers of type formation for cultivated plants—Southwestern Asia, Southeastern Asia, Mediterranean area, Abyssinia and Egypt, Mexico and South America. In 1935, the number had increased to eight by the subdivision of the Southeastern Asian and South American centers but was reduced to seven in 1939. Vavilov 's concept of centers of origin as centers of diversity has been challenged. J.R. Harlan, who is perhaps the most outspoken of his critics, takes issue with the "fundamental concept of "centers" as a universal phenomenon" [SCIENCE 174:468-474, 1971] His evaluation of the theory is based on a partialrecord of Vavilov 's prolific writings. In this regard, Dorofeyev and Filatenko suggest that contemporary critics have not paid due attention to the theory's progressive 20-year development, which saw change in concept and terminology. With the availability of this complete compilation of articles and lectures, a more comprehensive evaluation of this theory is now possible.
Included in the 24 chapters are reports on plant expeditions—Vavilov himself visited 52 countries—that embodied the mission of the VIR "to bring the best plant resources of the world to the service of socialistic agriculture" (p. xiv). Over the 15 years of active plant exploration (1924-1939), Vavilov and his colleagues collected agricultural plants in the field and market-place, observed and documented agricultural methods, studied the ecology and geography of each country and region they visited, and conducted genetic and agronomic studies of the germplasm they brought to the institute and its field stations. In the early years of the VIR program, the research effort was built upon the phytogeographic method introduced in the latter half of the 19th century by the Swiss botanist Alphonse de Candolle. Botanical and genetic techniques used in the study of phytogeography were refined by concentrating on infraspecific variation, distributions of this variation both past and present, and taxonomic differences (p.32). At the end of Vavilov's career, in a lecture delivered before the Soviet Academy of Sciences (pp. 421-442), Vavilov acknowledged Charles Darwin as the greater influence and driving force behind the development of his theory of cultivated plant origins. It was upon Dar-win's concept of "centers of origins of species" (p. 451) that Vavilov operated with a view toward the "interrelated variation, heredity and selection" (p. 423), factors incorporated into Darwin's explanations of the evolutionary process. Vavilov's statement that de Candolle's work was "one-sided" (p.424) is an interesting comment in light of Harlan's assessment that "the modern approach is more in the tradition of de Candolle than Vavilov" [SCIENCE 174:468-474, 1971].
The articles and lectures in this volume, which are arranged chronologically, trace the development of an evolutionary concept which goes far beyond the geographic demarcation of centers of origin. They document a theory that dramatically changed the direction of plant breeding and essentially laid the groundwork for modem-day germplasm programs. In these writings, Vavilov expounds upon the evolution of plants and animals under domestication, the genetics of type-formation and variation in and out of the geographic centers, the changes in biological patterns that occurred in one center versus another, how artificial and natural selection acted in the domestication process, and the ecological patterns shared in common by all the centers. Included with the translations are the original distribution maps, photos and draw ings of agricultural implements and plants, compilations of plant distributions and infraspecific variation, and tables recording data from agronomic and inheritance studies.
The value of this publication will be found principally within a historical context. It will be a useful resource volume for a variety of researchers—geneticists, plant breeders, botanists, ethnobotanists, and science historians. Indexes to plant names (Latin and vernacular), animal names, and centers of origins allow easy access to the location of each item as it is treated throughout the 24 chapters. An index for the textual content, which is not present, would have been useful. The price may prove prohibitive, an unfortunate limitation that will affect the book's accessibility. The book itself provides the international scientific community with the full record of one part of Vavilov's extensive contribution to mod-ern biology. Perhaps it will help to stimulate Western science to undertake a more comprehensive reassessment of his accomplishments.—Laura A. Morrison, Oregon State University, Corvallis.
Molecular, Biochemical and Physiological Aspects of Plant Respiration H. Cambers and L.H.W. Van der Plas, eds. ISBN 90-5103-079-7 (cloth US$148.00). SPB Academic Publishing bv, P.O. Box 97747, 2509 GC The Hague, The Netherlands.—Chapters in this book are based on 82 presentations made during the "Third Plant Respiration Meeting" held in Utrecht (1991). The text is very comprehensive and its coverage is basically divided into three sections: Electron Transport Chains; Interactions Between Mitochondria, other Cell Organelles and the Cytosol; and Biogenesis of Mitochondria and Molecular Aspects of Plant Respiration. The book is very informative and would be a valuable text for those actively involved in respiration biochemistry. Its major draw-back is that discipline-specific abbreviations are utilized throughout the text and this makes it difficult to comprehend for anyone not recently trained in the discipline.—James W. Wallace, Jr., Western Carolina Univ., Cullowhee NC
Cellular Communication in Plants. Richard M. Amasino, Ed. 1993. ISBNO-306-44415-1 (cloth US$69.50) Plenum Publishing Corp., 233 Spring St., New York NY 10013.—Plants share with animals the ability to sense external stimuli and to transmit signals representing external stimuli and internal changes throughout the organism. We know quite a lot about signal perception, transduction, and cellular communication in animals but remarkably little about the molecular, cellular and structural basis for these actions in plants.
By bringing together a group of papers on transduction and cellular communication in plants, the present volume, the Proceedings of the Twenty-First Steenbock Symposium, held in Madison, Wisconsin in 1992, not only serves to summarize current work in cellular communication in plants but also heightens awareness of the importance of this developing field among those from other areas of research. The nineteen papers in this volume represent a spectrum of work ranging from "Signal Perception in Plants" to "Cell Communication and the Coordination of Differentiation." In addition to the papers, abstracts are presented for 44 talks and posters.
I was somewhat disappointed when I first opened this short volume and found a lack of cohesiveness among the papers. Even after spending some time with this book, I have emerged from the text with many details but a poor overview of cell communication in plants. I do not think that this is the fault of the symposium organizers or the individual authors. Rather, it is indicative of our lack of detailed knowledge of the many facets of plant cell communication. This field could benefit especially from the increased funding supplied by a major research initiative.
Overall, I am glad to have Cellular Communication in Plants on my bookshelf. It provides a view into one of the most important, developing research areas in the biological sciences.—Thomas J. Herbert, University of Miami, Coral Gables, FL
Origin of Land Plants. Linda E. Graham. 1993. ISBN 0-471-61527-7 (cloth, (US$89). John Wiley & Sons, Inc., 605 Third Avenue, New York, New York 10158, USA—This is the first comprehensive review of the topic in 85 years, says the publisher. The chapter titles make it clear what the book covers: An Introduction to Land Plant Origins; Early Silurian and Late Ordovician Environments; Approaches to an Under-standing of Early Land Plant Evolution; The Charophycean Algae; Morphology, Ecology, and Physiology of Charophytes; Gaps Between Charophycean Algae and Land Plants; Evolution of Plant Morphology: Cell Walls, etc.; Evolution of Plant Sexual Reproduction; Origin of Plant Signal Transduction Systems, etc.; and Land Plant Origins—A Summary. To call this book "comprehensive" is an understatement.
The author appears to have cited every relevant reference; scarcely any important point lacks a modern reference to the primary literature, including some from [early] 1993.1 found but one exception: page 234, "The closest marine relatives of the [land] plant lineage were most likely scaly, unicellular flagellates. Land plants almost certainly did not arise from multicellular sea-weeds that washed up onto beaches and sprouted there—a concept often presented in introductory textbooks." I've never seen such a thing in print; no references to such books are given — to protect the guilty, perhaps. Because the book is everywhere marked by the most careful scholarship, one wonders whether the publisher's lawyers asked Graham to delete the citations!
Throughout, the author repeatedly tells us what is not known and she states explicitly what studies need to be undertaken to support or repudiate a given line of reasoning. I find this rare, and I compliment the author for taking such an approach.
Definitions for possibly obscure words are given regularly. Symplesiomorphy, autapomorphy, homoplasy: all are defined parenthetically where they first occur, and sometimes again in later pages. Graham is a teacher, and it shows.
The book is lavishly illustrated. There is a problem with the very numerous electron micrographs (and may-be for some readers some of the light micrographs as well): they need marker arrows to point to the relevant structure or organelle. Those well versed in interpreting electron micrographs will probably have no trouble. However, I found I lost the thread of the argument on several occasions, until I took the book to my local friendly electron microscopist, and he set me straight very quickly, and commented on the excellence of some of the pictures as well.
The last chapter happily includes clever cartoons by the author's husband and co-worker, James Graham. These mostly feature a stylized anthropomorphic Coleochaete with two supraocular antennae. In some, the antennae are lacking—the artist's sly way of suggesting the loss of biflagellate zoospores as Charophycean algae gave rise to the first terrestrial plants.
This is a masterful synthesis of paleobotany, biochemistry, morphology, ecology, cladistics, and classical life cycle studies. Because the author points so clearly to what lines of research need to be pursued, one can anticipate that a second edition is not so many years away. Meantime, buy it; read it; it deserves a wide audience.—Neil Harriman, University of Wisconsin-Oshkosh
Weed Seeds ofthe Great Plains, A Handbook for Identification Linda W. Davis. 1993, vi + 145 pp., ISBNO-7006-0651-3 (cloth US$25.00), University Press of Kansas, 2501 W 15th St., Lawrence KS 66049-3904—Much of the vast Great Plains region of the United States has been converted to farm and range-land. Control of undesirable native or introduced plant species that occur in this region is necessarily of great importance to agribusiness. One of the most effective and environmentally sound methods of weed control is the detection, identification and removal of weed seed contaminants in crop seed. The purpose of this aptly titled handbook is to present a system that will enable users to compare, distinguish and identify the seeds, fruits or disseminules of 280 common or problematic weed species (mostly herbs) that occur in the region. True to this purpose, discussions of seed biology and dispersal, plant anatomy, systematics or allied topics are not included. Readers desiring information on these subjects are free to consult works that appear in the annotated list of references provided in the introduction. After brief introductory remarks the author proceeds directly to a clear explanation of the system and how to use it.
The author has devised a useful multiple-entry key based on 22 non-technical characters describing conspicuous macroscopic features of the various disseminules such as size, three-dimensional form, and gross surface ornamentation or texture. To identify an unknown seed, one simply selects an obvious character exhibited by the seed and locates the appropriate "finding list" containing the subset of taxa whose disseminules exhibit that character. Most of the disseminules included in this handbook possess several salient features and so appear on more than one finding list. The user thus is afforded the luxury of several "correct" starting points from which to initiate a search. The subset of taxa appearing in each finding list is further divided into "subgroups," each based on an additional distinguishing character. Upon identifying the subgroup of taxa containing the possible match (3–14 taxa) the user has two options. One may either check the unknown against the excellent color enlargements of each of the disseminules of that subgroup or turn to the written description of each for a summary of the important disseminule characters and information about its range, preferred habitat, familial assignment and common name(s). Life-size silhouettes of several representative disseminules accompanying each description offer an additional opportunity to visually compare the unknown disseminule with those of the particular entity described. Exercising either option results in a quick and successful identification of the unknown disseminule, provided of course, it is one of the species treated.
The merits of this system are several. Foremost, in my opinion, is the careful avoidance of technical jargon wherever possible. This is evident in the selection of characters used to construct the findings lists, where terms such as "spherical," "bristles" and "chiplike form" are the norm and "floret," "bract" and "apical collar" are the exception. As a result, the entire book is "user-friendly" and readily accessible to the non-specialist. Two glossaries are provided to elucidate the smattering of botanical terms employed for the sake of precision and clarity. The second of these illustrates descriptive terms for basic shapes and surface textures by means of simple line drawings.
The book os not so large (26 x 18.5 cm) as to preclude its use as a field manual; its quality paper, sturdy binding and cloth-covered boards will surely endure frequent use outside of the laboratory. The individual user is left to solve the problem of extracting tiny seeds of Capsella bursa-pastoris or Hypericum perforatum from the gutter between the pages should a puff of wind lodge them there while performing identifications. I suggest that perhaps microforceps should follow handlens on the list of necessary gear that should be carried with this volume into the field.
This handbook, unmatched in its taxonomic and geographic coverage and centerpiece (literally) of beautiful photographs, will be a standard reference for the identification of Great Plains weed seeds. Its usefulness will not be restricted to specialists at private and governmental seed certification agencies. Straightforward and concise, it will serve a broad spectrum of students and practitioners of taxonomy, agronomy, agribusiness, conservation, archeology and paleobotany.—Victor Call, University of Florida
