Book Description
This book is a concise and well-illustrated treatment of the conventional knowledge and modern utilities of earthworms. The first two chapters deal with earthworm morphology, food relationship, behavior, functional role, interaction with soil biota, and the influence of environmental factors. Earthworms found in the tropics and sub-tropics are also discussed in this section. The third chapter provides a good account of utilizing species of worms to produce high value manure through vermitechnology and its application in agriculture. The nutritional and medicinal values of earthworms are illustrated in the fourth chapter, while the fifth c provides information on how earthworms are used successfully as indicators of ecological perturbations, soil quality and for remediation of contaminated soils. The book will immensely benefit students, faculty and researchers in biological, agricultural and environmental sciences. It is also a source of information for anyone interested in knowing more about earthworms.

Book Description
'Darwin cleared: official' This 1982 Times (7 January) head line of a first leader, reporting the astonishing case brought in Arkansas against compulsory teaching of a biblical account of creation, hopefully set at rest doubts about Darwin in the minds of a public confused by media presentations of such unfamiliar concepts as punctuated equilibria, cladism and phenetics. Mud sticks, but Darwin's perturbed ghost may have found some consolation in the concurrent celebrations at Grange-over-Sands, a modest township in Cumbria, UK, of the centenary of the publication of his less controversial book The Formation of Vegetable Mould through the Action of Worms. In the form of a symposium on earthworm ecology, this attracted some 150 participants, predominantly adrenalin-charged research workers in the full heat of peer-group interaction. This book comprises a selection of the more ecologically oriented papers contributed to the symposium, brutally edited in the interests of brevity and thematic continuity. The book opens with an appraisal of Darwin's earthworm work in its historical and philosophical context and relates his views on 'vegetable mould' to current concepts of humus formation. Thereafter, quotations from Darwin made out of piety have been rigorously excluded. Subsequent sections each comprise a review chapter and two or three 'case studies' presenting new data on a related topic.

Book Description
Difficult to obtain in its original print this classic work on ecology is a fascinating read for anybody with a passion for systems in the natural world. Originally published in 1896. Contents include; Habits of Worms, The amount of fine earth bought up by worms to the surface, The part which worms have played in the burial of Ancient Buildings, The action of worms in the Denudation of the Land, The Denudation of the Land and Conclusion... Introduction: The share which worms have taken in the formation of the layer of vegetable mould, which covers the whole surface of the land in every moderately humid country, is the subject of the present volume..... Many of the earliest books, particularly those dating back to the 1900's and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork. It comes complete with a specially commissioned new biography of the author.

Book Description
It is generally recognized that where earthworms are abundant they can exert significant influence on the structure and function of soils. Compared to other biogeographic regions of Earth, however, surprisingly little is known about the earthworm fauna of the western hemisphere and their role in soil processes. This book is the first comprehensive review and analysis of the state of understanding of earthworm biogeography and ecology in North America. Topics of in-depth discussion include earthworm systematics, biogeography and ecology, influences on soil structure and ecosystem nutrient dynamics, and implications for ecosystem management. Each chapter provides a general review and statement of current understanding, an assessment of current research problems, recent developments and advances, and priorities for future research and applications. This book is a must for researchers and students studying the soil-related facets of terrestrial ecology.

Book Description
Animals as geomorphic agents have primarily been considered "curiosities" in the literature of geomorphology, whose spatial and quantitative influences have been seen as both limited and minor. Zoogeomorphology: Animals as Geomorphic Agents examines the distinct geomorphic influences of invertebrates, ectothermic vertebrates, birds, and mammals, and demonstrates the importance of animals as landscape sculptors. Specific processes associated with the diversity of animal influences in geomorphology are examined, including burrowing and denning, nesting, lithophagy and geophagy, wallowing and trampling, food caching, excavating for food, and dam building by beavers. Particular emphasis is placed on terrestrial animals, although aquatic animals are also discussed where appropriate. This book, which is the only one available wholly devoted to this topic, will interest graduate students and professional research workers in geomorphology, ecology, environmental science, physical geography, and geology.
