Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Plant Ecology Man could not live without plants. They are the source of all food, practically all fuel, and all important natural fibers except wool and silk which are obtained from animals that feed upon plants. They are also the direct source of rubber, paper, most drugs, and very many other products without which the progress of civilization would have been absolutely impossible. There can be no question of the desirability of studying objects that are of such very great importance to our health and comfort, indeed to our very existence, as are plants.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Field Manual of Plant Ecology Having taught plant ecology at the University of Michigan Biological Station during the past thirty-two summers, the author has acceded to repeated requests for a manual based on this course. The course was initiated and developed in line with Agassiz's famous maxim: Study nature, not books, in addition to which special effort was made to use as little and as simple apparatus as possible. The aim was to work with plants at all times. Both high-school and college students can use the manual with suitable modification in any part of the country.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Study of Plants: An Introduction to Botany and Plant Ecology The course of work followed in this book is directed, in the main, to the establishment of the fundamental principles of Plant Physiology. Plant Morphology receives a less extended treatment; but this aspect of the subject is freely introduced in the discussion of Plant Ecology, i. E. The relation of the structure and functions of plants to their habitat. More space has been devoted to Ecology than is usual in an ele mentary text-book, but the Author believes that this aspect of plant life gives to field work a more definite aim, and broadens the outlook of the student by linking up Botany with the study of climate, geology, and topography. Similarly, to avoid the weariness of lessons dealing merely with the comparison of forms, the Author has throughout treated the forms of roots, stems, and leaves in relation to their functions and to the habitat of the plant.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Plant Physiology and Ecology The point of view and the methods of study first advanced in "Research Methods in Ecology" have proved so satisfactory in teaching as to make it desirable to embody them in a text-book. The present text has been based largely upon "Research Methods," though most of the matter is new or rewritten. The manner of treatment is essentially the same, but the subject-matter has been rearranged and broken up into a larger number of chapters. The plant is first considered as an individual, with respect to factor, function, and form, and then as a member of a plant group or formation. The reasons for regarding ecology and physiology as essentially the same have been given elsewhere, and need not be repeated here. An endeavor has been made to give the various parts of this vast field their proper importance. Since ecology and physiology are merged, it is manifestly impossible to give to either what would be regarded as a complete treatment by a specialist in either line. No attempt has been made to touch all the points in each, but it is thought that nothing really fundamental has been omitted. The book is intended for use with classes in second-year botany in college and university. In manuscript form, it has been in such use for two years with good results. Although the amount of laboratory and field work is large, it is possible to accomplish all of it in a course requiring 6-8 hours of laboratory time each week. This can be done only by careful planning on the art of both instructor and student, and for this reason the following suggestions are offered as aids. The instructor will find it imperative to plan in advance for the experiments for the whole year, in order that plants may be ready as needed. Seeds and fruits for the study of migration should be collected in the fall. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Bio-Ecology From the beginnings of life, organisms have lived together in some kind of grouping. Since the differentiation of plants and animals, communities in which both occurred and interacted have undoubtedly characterized the arrangement of living things on the face of the earth. We know now that there are no habitats in which both plant and animal organisms are able to live, in which both do not occur and, influence each other. In contrast, the development of the science of ecology has been hindered in its organization and distorted in its growth by the separate development of plant ecology on the one hand and animal ecology on the other. The authors were brought together in this task of attempting to correlate the fields of plant and animal ecology by the common belief that it would tend to advance the science of ecology in general. It was this common interest rather than agreement in all matters which led to the initiation of this book as a joint project several years ago. In part, it grew out of the fact that the junior author's experience in dealing with the marine communities of the Puget Sound region had led to the discovery of community phenomena paralleling those found on land and fitting the system of classification in use by the senior author.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Biology of Flowering Plants This book is an attempt to give an account of the way in which the flowering plant lives, especially in relation to its environment. This, it might be said, is the aim of ecology but ecology approaches the plant as a member Of a community, while biology, as it is understood here, is interested rather in the plant as an individual. In its methods biology has, during the last generation, become more and more experimental; it builds on a foundation of physiology. A certain amount of pure physiology must therefore be introduced. The difficulty of giving enough to make the foundation sound, and yet not so much as to obscure the picture, has been fully realised, though perhaps not overcome.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Ecology: Continuing the Plant World My purpose today is to draw your attention briefly to certain facts and tendencies in the field of ecology. All life is controlled by two great forces, heredity and environment, and ecology is the science dealing with the environment. It therefore covers practically the whole field of biology, and is related in one way or another to every science which touches life. There have 'been three stages in the development of the biological sci ences: first, a period of general work, when Darwin, Agassiz and others amassed and gave their knowledge of such natural phenomena as could be studied with the limited methods at hand; next, men Specialized in different branches, and gradually built up the biological sciences which we know today; and now has begun the third or synthetic stage. Since the biological field has been reconnoitered and divided into its logical parts, it becomes possible to see the interrelations and to bring these related parts more closely together. Many sciences have been developed to the point where, although the field has not yet been fully covered, contact and cooperation with related sciences are essential to full development. Ecology represents the third phase. You have but to glance at the list of ecological problems drawn up by the Committee on Cooperation of the Ecological Society and appearing in Science for January 16, 1920. And this list is far from complete. You will see problems requiring work by zoologists, botanists, foresters, geographers, meteorologists, soil chemists, soil physicists, bacteriologists, and geologists, to mention only some of the leading lines.

Book excerpt: Excerpt from A Textbook of Plant Physiology Plant physiology is an inseparable part of botany. It is closely connected with the study of morphology and anatomy of plants, since without a sufficient knowledge of plant structure an effective study of physiology is hardly possible. Recently plant physiology has been forming connections not only with plant ecology and plant geography but also with taxonomy. Plant physiology is passing gradually from the study of activities common to all plants to a consideration of the physiological distinctions that exist between various groups or even species.

Book excerpt: Excerpt from Plant Succession: An Analysis of the Development of Vegetation The present book constitutes the general part of a monograph on Rocky Mountain vegetation which has been under way since 1899. It is hoped that another volume dealing with the details of the development and structure of the climax formations of the Great Plains, Rocky Mountains, and Great Basin may appear subsequently. The general principles advanced here are an outgrowth of the treatment in the "Development and Structure of Vegetation" (1904) and "Research Methods in Ecology" (1905), in which an endeavor to organize the whole field of present-day succession was made for the first time. The studies of the past decade have confirmed and broadened the original concepts, and have led irresistibly to the conclusion that they are of universal application. The summer of 1913 and the spring and summer of 1914 were spent in testing both principles and processes throughout the vegetation of the western half of the continent. The area scrutinized extends from the Great Plains to the Pacific Coast and from the Canadian Rockies to the Mexican boundary. The great climax formations of this region were traversed repeatedly, and their development and relations subjected to critical analysis and comparison. As a consequence, it is felt that the earlier concept of the formation as a complex organism with a characteristic development and structure in harmony with a particular habitat is not only fully justified, but that it also represents the only complete and adequate view of vegetation. This concept has been broadened and definitized by the recognition of the developmental unity of the habitat. As a result, formation and habitat are regarded as the two inseparable phases of a development which terminates in a climax controlled by climate. Hence, the basic climax community is taken to be the formation, which exhibits seral or developmental stages as well as climax units. It is hardly necessary to point out that this places the study of vegetation upon a purely developmental basis, which is as objective as it is definite. The recognition of development as the cause and explanation of all existing climax formations forced the conclusion that all vegetation has been developmentally related; in short, that every climax formation has its phylogeny as well as its ontogeny. This led at once to the further assumption that the processes or functions of vegetation to-day must have been essentially those of the geological past, and that the successional principles and processes seen in existing seres hold equally well for the analysis of each eosere. As a consequence, it has been possible to sketch in bold outline the succession of plant populations in the various eras and periods, and to organize in tentative fashion the new field of paleo-ecology.

Download or read book A Laboratory Course in Plant Physiology written by William F. Ganong and published by . This book was released on 2015-07-26 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Laboratory Course in Plant Physiology: Especially as a Basis for Ecology If the present book is found to have any merit in its particular field, it will consist chiefly in its practicability. With but few and clearly indicated exceptions, everything recommended in it has been repeatedly tested and found effective both by my students and myself. The book is the resultant of six years of effort and experiment directed to this end with classes of from eight to twelve students. The illustrations of the experiments are in every case from photographs of experiments in successful operation. Such pictures, while inferior in clearness of detail and perhaps in artistic effect to good drawings, have at least this conspicuous merit, that they may be accepted and followed with perfect confidence. In developing the course and the experiments herein recommended, I have tried to utilize, and, naturally, to improve upon, the best work done by others in the same lines. Little account is taken in these pages of the exact appliances and methods with which the classical work of plant physiology has been done, for the investigation phases of the subject lie without the scope of this work, and they are, moreover, summarized admirably in Pfeffer's great Handbook. But all phases of plant physiology utilizable for purposes of general education are meant to be included.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Elementary Plant Biology In the judgment Of the authors the kind of biology most worth while for the average boy or girl of fourteen years Of age is not' one based primarily on structure. Young stu dents are naturally more interested in activities or func tions than they are in mere form or structure. Hence, if we wish to work with, rather than against the grain, we must put function in the foreground of our discussion. Every boy and girl knows, too, that both plants and animals as well as human beings must have food and drink, and that they grow and reproduce their kind. It is relatively much easier, therefore, to unify a course like this along physiological lines than on the basis of morphology, or of homologies of structure, many of which are far too complicated to be made clear to young students.
