Seed Ecology
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 discu...
Micro Mischief
Wouldn't it be nice to end our dependence on foreign oil, and fuel automobiles with a cheap and abundant energy source? Corith College scientist George Hollaway thinks he's found the answer to this dilemma when he finally succeeds in squeezing fuel from the tenacious kudzu plant. But when George seeks financial advice for his discovery from newly hired economics professor Dia Fenner, he receives some bad news. He's overlooked some key costs in producing kudzu fuel that make the alternative unprofitable in today's marketplace. Yet powerful forces see kudzu fuel as the ticket to their dreams, including the interim college president and two influential businessmen. When Dia persists in presenting her economic arguments questioning the fuel, she first finds her job-then her life-in jeopardy. Her house is vandalized, she's attacked, and shadowy figures stalk her. Someone is trying to silence Dia. Will they succeed?

Seeds
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 in...
The Ecology of Seeds
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.
