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.

Available in PDF, EPUB and Kindle. Book excerpt: "The earthworm has been known since ancient times for its valuable services to soil fertility management and litter nutrient cycling. The Greek philosopher Aristotle named earthworm "the guts of the soil" because of its direct role in soil formation through gut fragmentation of large soil particles, forming fine soil aggregates rich in organic matter. The famous natural scientist Charles Darwin also described the importance of earthworms in the natural world and he wrote the document entitled "The Formation of Vegetable Mould Through the Action of Worms with Observation on Their Habits" in 1881, observing that "worms have played a more important part in the history of the world than most persons would at first suppose." During the last 30-40 years, earthworms have been studied intensively in the various disciplines of animal ecology, pedology, waste recycling, agriculture science, soil biology and chemistry, ecotoxicology, and pharmaceutical sciences. Because of their importance in soil and below-ground ecology, earthworms have been designated as "ecosystem engineers". Soil fertility maintenance, soil litter decomposition, soil microbial communities and other detritus community structures and their function are directly or indirectly affected by earthworms' presence in soils. Apart from that, earthworms have appeared as a promising tool to recycle nutrients from various kinds of organic waste substances and stabilization of industrial sledges. Vermicomposting could be a valuable and low-cost technique for farmers for onsite waste management and nutrient-rich manure production. Scientists are always looking for new species for solid waste management. Thus, scientists around the world are working on earthworm biodiversity assessment and evaluation of their ecosystem services and value addition in other environmental management sectors. Efforts have been made in this edited volume to compile recent advancements in earthworm biology and their promising services in different fields of environmental management and resource conservations. This book contains three sub-sections: earthworm ecology, vermicomposting, and earthworm ecotoxicology. A total of 17 chapters are included in this edited volume. In the first section two chapters cover phylogeny and distribution of earthworm, and distribution of earthworm in Canadian ecozones; in the second section a total of seven chapters are included describing the role of vermitechnology in bioremediation of agriculture waste, pharmaceutical waste substances, industrial sludge stabilizations, and soil nutrient supply; and the third section includes eight chapters describing the effect of various hazardous substances like pesticides, microplastics, heavy metals, and neonicotinoids on earthworm growth, survival, reproduction and toxicity. In the end, we acknowledge the people and family members who are directly or indirectly associated with the compilation of this book. Without their moral and technical support, this book would not see the light of day"--

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.

Book excerpt: Earthworms are often recognised 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-orthogonalisation 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 mineralisation 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.
