Book Description
Although plants comprise more than 90% of all visible life, and land plants and algae collectively make up the most morphologically, physiologically, and ecologically diverse group of organisms on earth, books on evolution instead tend to focus on animals. This organismal bias has led to an incomplete and often erroneous understanding of evolutionary theory. Because plants grow and reproduce differently than animals, they have evolved differently, and generally accepted evolutionary views—as, for example, the standard models of speciation—often fail to hold when applied to them. Tapping such wide-ranging topics as genetics, gene regulatory networks, phenotype mapping, and multicellularity, as well as paleobotany, Karl J. Niklas’s Plant Evolution offers fresh insight into these differences. Following up on his landmark book The Evolutionary Biology of Plants—in which he drew on cutting-edge computer simulations that used plants as models to illuminate key evolutionary theories—Niklas incorporates data from more than a decade of new research in the flourishing field of molecular biology, conveying not only why the study of evolution is so important, but also why the study of plants is essential to our understanding of evolutionary processes. Niklas shows us that investigating the intricacies of plant development, the diversification of early vascular land plants, and larger patterns in plant evolution is not just a botanical pursuit: it is vital to our comprehension of the history of all life on this green planet.

Book Description
Reviewers from diverse branches of botany have exerted pressure to have chapters dealing with their field extended. If only to cover his incompetence, the author could not accede to these requests. Nor was it possible to respond to Eastern European urgings to extend the classificatory terminology, especially in ChapterX. He is grateful for indications of factual shortcomings in the chosen field, especially for those by Dr. RUDOLF SCHMID (Ann Arbor), who provided exten sive comment. L. VAN DER PIlL The Hague, spring 1972 Preface to the First Edition The work offered here is a companion volume to the work by K. FAEGRI and 1. VAN DER PIJL, Principles of Pollination Ecology, whim. deals with the preced ing phase of reproduction in plants. In the present work too, the emphasis is on principles and ecology. It is neither an enumeration of mechanisms, nor a compilation of cases. RIDLEY'S monumental work The Dispersal of Plants Throughout the World comprises 700 large pages of small print, and research has proceeded since then. Though this work is more than just a compilation and contains much insight and thoughts on principles in addition to reviews, its completeness hinders its use as a text book. As a reference work, it is unsurpassed and the writer made frequent use of it. The writer paid special attention to functional backgrounds for the use of taxonomists working with "characters" and to biosystematics at the macro-level.

Book Description
The original suggestion to organize a symposium about the classi fication and evolution of the Flowering Plants was made at, the International Botanical Congress at Leningrad in 1975, and the idea was so well accepted by several colleagues that plans for such a symposium quickly took shape. An organizing committee consisting of Professor H. MERXMULLER, Miinchen, Professor V. H. HEYWOOD, Reading, and Professor K. KUBITZKI, Hamburg, was set up. The conference took place on 7-12 September 197tl in the Institut fiir Allgemeine Botanik of the University of Hamburg under the auspices of the International Association for Plant Taxonomy and was at tended by 80 participants from 14 countries. There have been several meetings in recent years which have dealt with the origin and evolution of the Flowering Plants so that it might be questioned whether yet another symposium dealing with more or less the same subject were really "justified. As the reader will see from the contents of the book, this symposium differed from similar ones held recently in two respects: 1. Emphasis was given to methodological aspects of the classification of higher taxa, and 2. much classificatory and evolutionary evidence relating to the higher taxa of Flowering Plants was presented.

Book Description
Many of the characteristics that distinguish plants from other living organisms can be traced to their bacterial origin early in the history of life. These features-such as a multicellular haploid life stage, prevalent hermaphroditism, self-fertilization, and general dependence on biotic and abiotic vectors for reproduction-stem directly from the plant's ability to obtain energy from the sun. This novel mode of energy capture had far-ranging implications for plant evolution. It not only fueled the tremendous diversification of life on Earth that followed, but also had far-ranging implications for the evolution of photosynthetic microorganisms and eventually for land plants. Understanding the evolutionary processes for the proliferation and diversification of plants requires an appreciation of their unique biological features. While the processes of mutation, selection, genetic drift, and gene flow remain the same for both plants and animals, there are specific characteristics of plants that modify the way their evolution is implemented. Unique traits of plants affect everything from the fate of mutations, through exposure to selection in a haploid life phase, to the distribution of genetic variation within populations, and ultimately the rates and patterns of diversification. This book examines the origins of the unique evolutionary features of plants, as well as their implications for evolutionary processes. Author Mitchell B. Cruzan provides contemporary discussion of subjects including population genetics, phylogeography, phylogenetics, ecological genetics, and genomics. The book fills a need for modern coverage of these topics, all of which are essential to a wide range of advanced courses in plant biology.
