Seeds provide half of the calories consumed by humans today and helped grow human civilization. Just ten crops (rice, maize, wheat, potatoes, etc.) provide 75% of human energy needs. "Seeds: A Natural History" unearths the evolution of seeds from the time before dinosaurs to how they became our primary source of calories and protein today. Using vivid photos of seeds, which invite readers to appreciate their diversity of form and function, along with a text by an award winning science journalist and writer, "Seeds "harvests the importance of the nature and productivity of seeds. And to complete the narrative arc, Seeds" shows how modern scientific techniques of genetic profiling, seed banking, and plant breeding may be the answer to humanity s future. Seeds and humans have had a bountiful history and this book captures the scientific, artistic, and economic vitality of these incredible natural packages."

Charting the political, social, and environmental history of efforts to conserve crop diversity. Many people worry that we're losing genetic diversity in the foods we eat. Over the past century, crop varieties standardized for industrial agriculture have increasingly dominated farm fields. Concerned about what this transition means for the future of food, scientists, farmers, and eaters have sought to protect fruits, grains, and vegetables they consider endangered. They have organized high-tech genebanks and heritage seed swaps. They have combed fields for ancient landraces and sought farmers growing Indigenous varieties. Behind this widespread concern for the loss of plant diversity lies another extinction narrative that concerns the survival of farmers themselves, a story that is often obscured by urgent calls to collect and preserve. Endangered Maize draws on the rich history of corn in Mexico and the United States to uncover this hidden narrative and show how it shaped the conservation strategies adopted by scientists, states, and citizens. In Endangered Maize, historian Helen Anne Curry investigates more than a hundred years of agriculture and conservation practices to understand the tasks that farmers and researchers have considered essential to maintaining crop diversity. Through the contours of efforts to preserve diversity in one of the world's most important crops, Curry reveals how those who sought to protect native, traditional, and heritage crops forged their methods around the expectation that social, political, and economic transformations would eliminate diverse communities and cultures. In this fascinating study of how cultural narratives shape science, Curry argues for new understandings of endangerment and alternative strategies to protect and preserve crop diversity.

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

This book introduces the reader to synthetic or artificial seeds, which refer to alginate encapsulated somatic embryos, vegetative buds or any other micropropagules that can be used as seeds and converted into plantlets after propagating under in vitro or in vivo conditions. Moreover, synthetic seeds retain their potential for regeneration even after low-temperature storage. The production of synthetic or artificial seeds using micropropagules opens up new vistas in agricultural biotechnology. Encapsulated propagules could be used for in vitro regeneration and mass multiplication at reasonable cost. In addition, these propagules may be used for germplasm preservation of elite plant species and the exchange of plant materials between national and international laboratories. This book offers state-of-the-art findings on methods, applications and prospects of synthetic or artificial seeds.

A New York Times Book Review Editors' Choice What Saladino finds in his adventures are people with soul-deep relationships to their food. This is not the decadence or the preciousness we might associate with a word like “foodie,” but a form of reverence . . . Enchanting." —Molly Young, The New York Times Dan Saladino's Eating to Extinction is the prominent broadcaster’s pathbreaking tour of the world’s vanishing foods and his argument for why they matter now more than ever Over the past several decades, globalization has homogenized what we eat, and done so ruthlessly. The numbers are stark: Of the roughly six thousand different plants once consumed by human beings, only nine remain major staples today. Just three of these—rice, wheat, and corn—now provide fifty percent of all our calories. Dig deeper and the trends are more worrisome still: The source of much of the world’s food—seeds—is mostly in the control of just four corporations. Ninety-five percent of milk consumed in the United States comes from a single breed of cow. Half of all the world’s cheese is made with bacteria or enzymes made by one company. And one in four beers drunk around the world is the product of one brewer. If it strikes you that everything is starting to taste the same wherever you are in the world, you’re by no means alone. This matters: when we lose diversity and foods become endangered, we not only risk the loss of traditional foodways, but also of flavors, smells, and textures that may never be experienced again. And the consolidation of our food has other steep costs, including a lack of resilience in the face of climate change, pests, and parasites. Our food monoculture is a threat to our health—and to the planet. In Eating to Extinction, the distinguished BBC food journalist Dan Saladino travels the world to experience and document our most at-risk foods before it’s too late. He tells the fascinating stories of the people who continue to cultivate, forage, hunt, cook, and consume what the rest of us have forgotten or didn’t even know existed. Take honey—not the familiar product sold in plastic bottles, but the wild honey gathered by the Hadza people of East Africa, whose diet consists of eight hundred different plants and animals and who communicate with birds in order to locate bees’ nests. Or consider murnong—once the staple food of Aboriginal Australians, this small root vegetable with the sweet taste of coconut is undergoing a revival after nearly being driven to extinction. And in Sierra Leone, there are just a few surviving stenophylla trees, a plant species now considered crucial to the future of coffee. From an Indigenous American chef refining precolonial recipes to farmers tending Geechee red peas on the Sea Islands of Georgia, the individuals profiled in Eating to Extinction are essential guides to treasured foods that have endured in the face of rampant sameness and standardization. They also provide a roadmap to a food system that is healthier, more robust, and, above all, richer in flavor and meaning.

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.
