Plant Taxonomy
Author: Tod F. Stuessy
Publisher: Columbia University Press
ISBN: 0231518641
Category : Science
Languages : en
Pages : 566
Book Description
The field of plant taxonomy has transformed rapidly over the past fifteen years, especially with regard to improvements in cladistic analysis and the use of new molecular data. The second edition of this popular resource reflects these far-reaching and dramatic developments with more than 3,000 new references and many new figures. Synthesizing current research and trends, Plant Taxonomy now provides the most up-to-date overview in relation to monographic, biodiversity, and evolutionary studies, and continues to be an essential resource for students and scholars. This text is divided into two parts: Part 1 explains the principles of taxonomy, including the importance of systematics, characters, concepts of categories, and different approaches to biological classification. Part 2 outlines the different types of data used in plant taxonomic studies with suggestions on their efficacy and modes of presentation and evaluation. This section also lists the equipment and financial resources required for gathering each type of data. References throughout the book illuminate the historical development of taxonomic terminology and philosophy while citations offer further study. Plant Taxonomy is also a personal story of what it means to be a practicing taxonomist and to view these activities within a meaningful conceptual framework. Tod F. Stuessy recalls the progression of his own work and shares his belief that the most creative taxonomy is done by those who have a strong conceptual grasp of their own research.

Patterns of Chloroplast Reproduction
Author: T. Butterfass
Publisher: Springer Science & Business Media
ISBN: 3709185610
Category : Science
Languages : en
Pages : 217
Book Description
The subject of this book has not been treated comprehensively before. For many years I have hesitated to attempt a monographic presentation because I felt uneasy about the idea of delineating something I am not sure about myself, and I felt it might be rash to try to integrate what seemed-and largely still seems-to consist of a heap of tessera not fitting together. The conviction won over, however, that the many details accumulated thus far call for some order now, and that an appraisal of where we stand would be appropriate. This book, I hope, can fill a gap barring the way to further progress in the field. It is not only a compilation of details but also an attempt to delineate the first outlines of a picture-blurry, obscure, and controversial as it must appear. The imagination of the research worker will be aroused, I hope, and stimulate further progress. In addition to data widely dispersed in the literature much unpublished material has been included. The limited space available prevented me from giving all the details known. The subject is also linked to many neighboring fields of study, but these relationships and their ramifications could not be discussed at length. This is a minor shortcoming, however, compared with our great ignorance of the subject in general.
