Book Synopsis Biology of Earthworms by : Ayten Karaca
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 316 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 Earthworms written by Clayton G. Horton and published by Nova Science Publishers. This book was released on 2017 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthworms are often recognized as key organisms in soil ecosystems. In Chapter One, the authors propose endozoochory (seed dispersal through ingestion) as a missing mechanism of Oligochaeta dispersal and put forward the fusion-orthogonalization model for the diversification and speciation of the Oligochaeta populations. Chapter Two discusses the biodiversity of earthworms in Madhya Pradesh, a central part of India. Earthworm diversity in some parts of India is still poorly explored, but findings suggest that the Madhya Pradesh region is rich in biodiversity of earthworms. In Chapter Three, a predation pressure is presented as an important variable which can be viewed as another type of pressure on the earthworm population, such as pollution, environmental stress or land management, causing additional or extrinsic mortality to earthworm population. Chapter Four covers the key role played by earthworms as ecosystem engineers through their bioturbation activities involving soil mixing, their influence on the decomposition and mineralization of litter by breaking down organic matter, and their influence on the gas and water exchange or nutrient transfer in the soil. Chapter Five reviews recent research regarding the assessment of various pollutants on earthworms with emphasis on the possible improvement of the investigation in soil pollution monitoring using these organisms.
Download or read book The Earth Moved written by Amy Stewart and published by Algonquin Books. This book was released on 2005-03-11 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Earth Moved, Amy Stewart takes us on a journey through the underground world and introduces us to one of its most amazing denizens. The earthworm may be small, spineless, and blind, but its impact on the ecosystem is profound. It ploughs the soil, fights plant diseases, cleans up pollution, and turns ordinary dirt into fertile land. Who knew? In her witty, offbeat style, Stewart shows that much depends on the actions of the lowly worm. Charles Darwin devoted his last years to the meticulous study of these creatures, praising their remarkable abilities. With the august scientist as her inspiration, Stewart investigates the worm's subterranean realm, talks to oligochaetologists—the unsung heroes of earthworm science—who have devoted their lives to unearthing the complex life beneath our feet, and observes the thousands of worms in her own garden. From the legendary giant Australian worm that stretches to ten feet in length to the modest nightcrawler that wormed its way into the heart of Darwin's last book to the energetic red wigglers in Stewart's compost bin, The Earth Moved gives worms their due and exposes their hidden and extraordinary universe. This book is for all of us who appreciate Mother Nature's creatures, no matter how humble.
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.
