Download or read book The Seeds of Dicotyledons Volume 1 written by E. J. H. Corner and published by Cambridge University Press. This book was released on 1976-04-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1976, Professor Corner's study is a major work of botanical scholarship and reference. The most unsatisfactory part of the classification of dicotyledons is the arrangement of their families into orders. In these volumes the author shows how important the seed is in classification. Systems of ordinal classification based on the flower are potentially misleading in as much as floral similarity is often the effect of polyphyletic convergence. A different system of classification based on the seed is outlined. The work is the result of more than thirty years' collection and study of seeds, particularly in the tropics. The account is published in two volumes. The text in this first volume has five introductory chapters leading up to the nature of the primitive arillate seed. There then follows in alphabetical order concise descriptions of the seed in families and certain of their genera. The second volume contains more than 600 original illustrations made by the author. The two volumes are unique sources of teaching and reference material for botanical institutions throughout the world.

Download or read book Flowering Plants Dicotyledons written by Klaus Kubitzki and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 663 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume - the first of this series dealing with angiosperms - comprises the treatments of 73 families, representing three major blocks of the dicotyledons: magnoliids, centrosperms, and hamamelids. These blocks are generally recognized as subclasses in modern textbooks and works of reference. We consider them a convenient means for structuring the hundreds of di cotyledon families, but are far from taking them at face value for biological, let alone mono phyletic entities. Angiosperm taxa above the rank of family are little consolidated, as is easily seen when comparing various modern classifications. Genera and families, in contrast, are comparatively stable units -and they are important in practical terms. The genus is the taxon most frequently recognized as a distinct entity even by the layman, and generic names provide the key to all in formation available about plants. The family is, as a rule, homogeneous enough to conve niently summarize biological information, yet comprehensive enough to avoid excessive re dundance. The emphasis in this series is, therefore, primarily on families and genera.

Book excerpt: Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

Available in PDF, EPUB and Kindle. Book excerpt: "Thsi guide provides, for the first time, an account of the seeds and other persistent parts of fruits for New Zealand plants. ... Because seeds survive long after most plant parts have deteriorated, the guide will assist in many sciences: in analysing diet from the gut, gizzard contents or faeces of mammals or birds, recreating past plant distributins from deposits in bogs or soils, and determining native food and criop plants at archaeological sites. And because seeds are relatively conservative structures in terms of their evolutionary diversification, it will also a wealth of information of use in plant identification and classification - a critical science for conservation of biodiversity."--Back cover.

Download or read book Seedtime written by Scott Chaskey and published by Rodale Books. This book was released on 2014-01-21 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scott Chaskey—working farmer, poet, and spiritual father of the community farming movement—considers "the web of biodiversity and resilience at the heart of our cultural inheritance" by masterfully weaving history, politics, botany, literature, mythology, and memoir into a beautiful and instructive book. It's hard to think of a subject more fundamental to the sustenance of the human race than seeds. Having coevolved with the Earth's plants, insects, and animals, seeds are entwined with the core myths of ancient cultures and the development of human consciousness. Their story remains vitally important today, as the corporations that manufacture GMOs threaten our food security and the future of seed-cultivated agriculture. The stakes, for those concerned with preserving biodiversity and ecological integrity, are high. Balancing a wide view of politics and history, Chaskey alights from life on the farm he has cultivated for 25 years to conjure Gregor Mendel's breeding experiments that yielded our modern understanding of genetics; he also introduces us to several "bioneers," such as the geobotanist Nikolay Vavilov and agriculturalist Cary Fowler, who are preserving global biodiversity through seeds. Integrating scholarship with accessible storytelling, Seedtime is a celebration as well as a call to action urging us to renew our role as citizens of nature, in ecologist Aldo Leopold's phrase, not as conquerors of it.

Download or read book Embryology of Angiosperms written by B. M. Johri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 850 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirty-four years have elapsed since the publication of the late Professor P. Maheshwari's text, An Introduction to the Embryology of Angiosperms, a work which for many years served as an invaluable guide for students and a rich source book for research workerso Various texts dealing with sections of the braad spectrum oftopics encompassed by Maheshwari in his book have appeared in the interim, but a compendious modem work dealing with the whole field has been lacking. This present volume splendidly meets the need, and it is altogether fitting that Professor B. M. lohri, long an associate and close colleague of Professor Maheshwari and himself a prolific contributor to the subject, should have undertaken the task of editing it. When Maheshwari wrote, it was stiIl feasible for one author to handIe the subject, but today even someone with his fine bread th of vision and depth of understanding could not, alone, do it justice. So the effort has to be a collaborative one; and Professor lohri's achievement has been to bring together a team of authoritative collaborators, assign them their responsibilities, and put them to work to produce a text as integrated in its treatment as the diversity of the subject would allow. The product vividly illustrates the advances that have been made in the study of angiosperm reproductive systems in the last 30 years, and the book is surely destined to become the new standard for student and researcher alike.

Download or read book Flowering Plants Dicotyledons written by Joachim W. Kadereit and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, 24 flowering plant families comprising a total of 911 genera are treated. They represent the asterid order Lamiales except for Acanthaceae (including Avicenniaceae), which will be included in a later volume. Although most of the constituent families of the order have been recognized as being closely related long ago, the inclusion of the families Byblidaceae, Carlemanniaceae and Plocospermataceae is the result mainly of recent molecular systematic research. Keys for the identification of all genera are provided, and likely phylogenetic relationships are discussed extensively. To facilitate the recognition of relationships, families are cross-referenced where necessary. The wealth of information contained in this volume makes it an indispensable source for anybody in the fields of pure and applied plant sciences.
