What determines the number and size of the seeds produced by a plant? How often should it reproduce them? Why and how are seeds dispersed, and what are the implications for the diversity and composition of vegetation? These are just some of the questions tackled in this wide-ranging review of the role of seeds in the ecology of plants. The text encompasses a wide range of concepts of general relevance to plant ecology, reflecting the central role that the study of seed ecology has played in elucidating many fundamental aspects of plant community function.

This book is about the regeneration of plants from seed under field conditions. It attempts to give a reasonably balanced overview of the many aspects of this broad topic. The first chapter introduces some general ideas about reproduction in plants. Subsequent chapters deal with the early stages in the life of a plant, from ovule to established seedling, in a more or less chronological order. The final chapter shows how the data on regeneration requirements of different species can be used to explain a number of important characteristics of whole plant communities. The study of the ecological aspects of reproduction by seed touches on a range of issues of current interest in biology. A discussion of seed size and number involves a consideration of the concepts of resource allocation, life cycles and strategies. The in teractions between plants and animals seen in pollination, seed dispersal and predation provide excellent material for the study of coevolution. Investigations on regeneration from seed have greatly our understanding of the causes and maintenance of species added to diversity. The reader will find that virtually all the experiments and field observations described in this book are conceptually very simple. Many of them merely required numerous careful measurements.

The new edition of Seeds contains new information on many topics discussed in the first edition, such as fruit/seed heteromorphism, breaking of physical dormancy and effects of inbreeding depression on germination. New topics have been added to each chapter, including dichotomous keys to types of seeds and kinds of dormancy; a hierarchical dormancy classification system; role of seed banks in restoration of plant communities; and seed germination in relation to parental effects, pollen competition, local adaption, climate change and karrikinolide in smoke from burning plants. The database for the world biogeography of seed dormancy has been expanded from 3,580 to about 13,600 species. New insights are presented on seed dormancy and germination ecology of species with specialized life cycles or habitat requirements such as orchids, parasitic, aquatics and halophytes. Information from various fields of science has been combined with seed dormancy data to increase our understanding of the evolutionary/phylogenetic origins and relationships of the various kinds of seed dormancy (and nondormancy) and the conditions under which each may have evolved. This comprehensive synthesis of information on the ecology, biogeography and evolution of seeds provides a thorough overview of whole-seed biology that will facilitate and help focus research efforts. Most wide-ranging and thorough account of whole-seed dormancy available Contains information on dormancy and germination of more than 14,000 species from all the continents – even the two angiosperm species native to the Antarctica continent Includes a taxonomic index so researchers can quickly find information on their study organism(s) and Provides a dichotomous key for the kinds of seed dormancy Topics range from fossil evidence of seed dormancy to molecular biology of seed dormancy Much attention is given to the evolution of kinds of seed dormancy Includes chapters on the basics of how to do seed dormancy studies; on special groups of plants, for example orchids, parasites, aquatics, halophytes; and one chapter devoted to soil seed banks Contains a revised, up-dated classification scheme of seed dormancy, including a formula for each kind of dormancy Detailed attention is given to physiological dormancy, the most common kind of dormancy on earth

Publisher: Elsevier
ISBN: 0323148654
Category: Nature
Page: 484
View: 4009
Ecology of Soil Seed Banks examines the factors that influence seed bank dynamics and the variety of patterns found among different species. This book presents seed banks in a community context to explore the ecological implications of different patterns, and thus begin the development of a synthesis by comparing various communities. Organized into five parts, this book first examines the general processes that influence inputs or losses from the seed bank, including predation, dormancy/germination mechanisms, and their evolutionary importance. Then, this text examines seed banks in a community context. Only eight vegetation types are included, but the range in diversity of life form, length of growing season, and dominant environmental conditions allow comparisons of seed bank patterns. This book also explores the role of seed banks in vegetation management. This reference material will be a valuable reference material to population and community ecologists and managers. Evolutionary consequences of seed banks should be of interest to population and theoretical biologists.

The Ecology of Trees in the Tropical Rain Forest


Author: I. M. Turner
Publisher: Cambridge University Press
ISBN: 9781139428873
Category: Science
Page: N.A
View: 6952
Our knowledge of the ecology of tropical rain-forest trees is limited, with detailed information available for perhaps only a few hundred of the many thousand of species that occur. Yet a good understanding of the trees is essential to unravelling the workings of the forest itself. This book aims to summarise contemporary understanding of the ecology of tropical rain-forest trees. The emphasis is on comparative ecology, an approach that can help to identify possible adaptive trends and evolutionary constraints and which may also lead to a workable ecological classification for tree species, conceptually simplifying the rain-forest community and making it more amenable to analysis.

Faith in a Seed

The Dispersion Of Seeds And Other Late Natural History Writings
Author: Henry D. Thoreau
Publisher: Island Press
ISBN: 9781597262873
Category: Nature
Page: 301
View: 4692
Faith in a Seed contains the hitherto unpublished work The Dispersion of Seeds, one of Henry D. Thoreau's last important research and writing projects, and now his first new book to appear in 125 years.With the remarkable clarity and grace that characterize all of his writings, Thoreau describes the ecological succession of plant species through seed dispersal. The Dispersion of Seeds, which draws on Charles Darwin's theory of natural selection, refutes the then widely accepted theory that some plants spring spontaneously to life, independent of roots, cuttings, or seeds. As Thoreau wrote: "Though I do not believe a plant will spring up where no seed has been, I have great faith in a seed. Convince me that you have a seed there, and I am prepared to expect wonders." Henry D. Thoreau's Faith in a Seed, was first published in hardcover in 1993 by Island Press under the Shearwater Books imprint, which unifies scientific views of nature with humanistic ones. This important work, the first publication of Thoreau's last manuscript, is now available in paperback. Faith in a Seed contains Thoreau's last important research and writing project, The Dispersion of Seeds, along with other natural history writings from late in his life. Edited by Bradley P. Dean, professor of English at East Carolina University and editor of the Thoreau Society Bulletin, these writings demonstrate how a major American author at the height of his career succeeded in making science and literature mutually enriching.

"The genius of Hanson's fascinating, inspiring, and entertaining book stems from the fact that it is not about how all kinds of things grow from seeds; it is about the seeds themselves." --Mark Kurlansky, New York Times Book Review We live in a world of seeds. From our morning toast to the cotton in our clothes, they are quite literally the stuff and staff of life: supporting diets, economies, and civilizations around the globe. Just as the search for nutmeg and pepper drove the Age of Discovery, coffee beans fueled the Enlightenment and cottonseed sparked the Industrial Revolution. Seeds are fundamental objects of beauty, evolutionary wonders, and simple fascinations. Yet, despite their importance, seeds are often seen as commonplace, their extraordinary natural and human histories overlooked. Thanks to this stunning new book, they can be overlooked no more. This is a book of knowledge, adventure, and wonder, spun by an award-winning writer with both the charm of a fireside story-teller and the hard-won expertise of a field biologist. A fascinating scientific adventure, it is essential reading for anyone who loves to see a plant grow.

Seeds are nature’s consummate survivors. The next time you admire a field of waving green grassland or a stunning grove of acacia, stop to consider how it got that way—often against incredible odds. Seeds can survive freezing temperatures and drought. They can pass through our digestive systems without damage and weather a trip across the ocean, hitching a ride on marine debris. They can even endure complete desiccation, a feat taken to extraordinary lengths by the date palm, a seed from which was recovered from the palace of Herod the Great was germinated after some two thousand years. The Book of Seeds takes readers through six hundred of the world’s seed species, revealing their extraordinary beauty and rich diversity. Each page pairs a beautifully composed photo of a seed—life-size, and, in some cases, enlarged to display fine detail—with a short description, a map showing distribution, and information on conservation status. The whole spectrum of seeds is covered here. There are prolific species like corn and less widely distributed species, like the brilliant blue seeds of the traveler’s palm or the bird of paradise flower, aptly named for its distinctive orange coiffure. There are tiny seeds and seeds weighing up to forty pounds. And while seeds in all their shapes, sizes, and colors grant us sustenance, there are even some we would be wise to treat with caution, such as the rosary pea, whose seeds are considered more toxic than ricin. The essential guide to these complex plant creations, The Book of Seeds offers readers a rare, up-close look that will inspire scientists and nature lovers alike.

Category: Science
Page: 322
View: 2935
Seed Dispersal focuses on the mechanics and processes involved in seed dispersal, including its implications in ecology, animal behavior, plant and animal biogeography, speciation, and evolution. The selection first elaborates on the aerial motion of seeds, fruits, spores, and pollen and seed dispersal by water. Discussions focus on seed dispersal by rain, river, and flood, effective seed dispersal by ocean currents compared to other vectors, aerodynamic forces and their effects, and launching and release mechanisms. The text then takes a look at seed dispersal syndromes in Australian Acacia, including inference of dispersal syndromes, seed dispersal syndromes, ecological consequences of seed dispersal, and evolutionary derivation of dispersal syndromes. The publication ponders on seed dispersal by fruit-eating birds and mammals, rodents as seed consumers and dispersers, and seed dispersal in relation to fire. Topics include fire as a dispersal vector, long distance dispersal, granivorous rodents and the fates of seeds, determinants of the fate path, population ecology of seed dispersal, and foraging for fruits. The selection is a valuable reference for researchers interested in the factors involved in seed dispersal.

Seeds of Sustainability is a groundbreaking analysis of agricultural development and transitions toward more sustainable management in one region. An invaluable resource for researchers, policymakers, and students alike, it examines new approaches to make agricultural landscapes healthier for both the environment and people. The Yaqui Valley is the birthplace of the Green Revolution and one of the most intensive agricultural regions of the world, using irrigation, fertilizers, and other technologies to produce some of the highest yields of wheat anywhere. It also faces resource limitations, threats to human health, and rapidly changing economic conditions. In short, the Yaqui Valley represents the challenge of modern agriculture: how to maintain livelihoods and increase food production while protecting the environment. Renowned scientist Pamela Matson and colleagues from leading institutions in the U.S. and Mexico spent fifteen years in the Yaqui Valley in Sonora, Mexico addressing this challenge. Seeds of Sustainability represents the culmination of their research, providing unparalleled information about the causes and consequences of current agricultural methods. Even more importantly, it shows how knowledge can translate into better practices, not just in the Yaqui Valley, but throughout the world.

Seed Biology: Insects, and Seed Collection, Storage, Testing, and Certification, Volume III brings together a large body of important information on seed biology. The book describes seed collection, identification, storage, testing, and certification. It also considers insects that directly affect seeds, seed-producing organs, or seed-bearing structures of plants. Organized into six chapters, this volume begins by outlining man’s dependency on seeds as source of food, fiber, spices, beverages, oils, vitamins, and drugs. Harmful effects of seeds are also mentioned. Separate chapters focus on seed development, dissemination, germination (including metabolism, environmental control, internal control, dormancy, and seed and seedling vigor), protection from diseases and insects, longevity, and deterioration. The book concludes with a discussion on the certification of field and tree seeds, the Organization for Economic Cooperation and Development certification schemes, and trends in seed certification. This book is a valuable source of information for seed producers and users as well as various groups of research biologists and teachers, including agronomists, plant anatomists, biochemists, ecologists, entomologists, foresters, horticulturists, plant pathologists, and plant physiologists.
