Book Description
What determines the number and size of the seeds produced by a plant? How often should it reproduce them? How often should a plant produce 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 authors bring together information on the ecological aspects of seed biology, starting with a consideration of reproductive strategies in seed plants and progressing through the life cycle, covering seed maturation, dispersal, storage in the soil, dormancy, germination, seedling establishment, and regeneration in the field. 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.

Book Description
This fascinating book is the first volume in a projected cultural history of the United States, from the earliest English settlements to our own time. It is a history of American folkways as they have changed through time, and it argues a thesis about the importance for the United States of having been British in its cultural origins. While most people in the United States today have no British ancestors, they have assimilated regional cultures which were created by British colonists, even while preserving ethnic identities at the same time. In this sense, nearly all Americans are "Albion's Seed," no matter what their ethnicity may be. The concluding section of this remarkable book explores the ways that regional cultures have continued to dominate national politics from 1789 to 1988, and still help to shape attitudes toward education, government, gender, and violence, on which differences between American regions are greater than between European nations.

Book Description
This technical reference applies to monitoring situations involving a single plant species, such as an indicator species, key species, or weed. It was originally developed for monitoring special status plants, which have some recognized status at the Federal, State, or agency level because of their rarity or vulnerability. Most examples and discussions in this technical reference focus on these special status species, but the methods described are also applicable to any single-species monitoring and even some community monitoring situations.We thus hope wildlife biologists, range conservationists, botanists, and ecologists will all find this technical reference helpful.

Book Description
Plant breeders continue to make significant advances in developing high yield ing, adaptable, disease-free crops. These advances, however, are not realized until an efficient seed production system is in place that rapidly increases geneti cally superior crops and makes them available to the consumer in large quantities at a reasonable cost. Successful seed production requires seed to be genetically pure, free of admixtures, and able to establish rapidly a uniform stand. Seed production is a complex process. Rigorous production criteria are followed by both seed producer and seed companies to ensure that high-quality seed is produced and marketed. These criteria become even more stringent in hybrid seed production. This volume identifies the factors most critical in a successful seed production operation. The fundamental considerations common to all seed crops are established in Part I, Principles of Seed Production. From this founda tion, the practices of seed production are provided in detail in Part II, Seed Production of Specific Crops.
