Download or read book Biology of Earthworms written by Ayten Karaca and published by Springer Science & Business Media. This book was released on 2010-11-09 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthworms, which belong to the order Oligochaeta, comprise roughly 3,000 species grouped into five families. Earthworms have been called ‘ecosystem engineers’; much like human engineers, they change the structure of their environments. Earthworms are very versatile and are found in nearly all terrestrial ecosystems. They play an important role in forest and agricultural ecosystems. This Soil Biology volume describes the various facets of earthworms, such as their role in soil improvement, soil structure, and the biocontrol of soil-borne plant fungal diseases. Reviews discuss earthworms’ innate immune system, molecular markers to address various issues of earthworm ecology, earthworm population dynamics, and the influences of organic farming systems and tillage. Further topics include the characteristics of vermicompost, relationships between soil earthworms and enzymes, the role of spermathecae, copulatory behavior, and adjustment of the donated sperm volume.

Download or read book Earthworm Ecology and Biogeography in North America written by Paul F. Hendrix and published by CRC Press. This book was released on 1995-02-22 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Earthworm Ecology written by Clive A. Edwards and published by CRC Press. This book was released on 2004-03-29 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthworm Ecology, Second Edition updates the most comprehensive work available on earthworm ecology with extensive revisions of the original chapters. New chapters analyze the history of earthworm research, the importance of earthworms as representatives of soil fauna and how they affect plant growth, the effects of the invasion of exotic earthworms into North America and other regions, and vermiculture and vermicomposting in Europe.This well-illustrated, expansive study examines the important and often overlooked impact earthworms have on the environment. It discusses the impact of climate, soil properties, predation, disease and parasitism, and competition upon earthworm ecology.

Download or read book The Physiology of Earthworms written by M. S. Laverack and published by Elsevier. This book was released on 2013-10-22 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Physiology of Earthworms focuses on the three species of earthworms — Liimbricus terrestris, Eisenta foetida, and Allolobophora longa. Other earthworms or oligochaetes such as the fresh-water species are briefly mentioned. The topics covered include the biochemical architecture; digestion and metabolism; calciferous glands; axial field; nitrogenous excretion; water relations; respiration; physiology of regeneration; neurosecretion; nervous system; and behavior of oligochaetes. This book is a good source of information for biology students and researchers conducting work on earthworms and its different species.
Download or read book Earthworm Ecology written by J. Satchell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: '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.

Download or read book Rediscovering Earthworms written by C.S.K. Mishra and published by Cambridge Scholars Publishing. This book was released on 2021-01-04 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
