Rediscovering Earthworms by C.S.K. Mishra,Suryasikha Samal Pdf
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.
Describes the digging habits, physical characteristics, reproduction process, and habitat of the earthworm and provides instructions for related hands-on science projects.
Terrestrial Earthworms (Oligochaeta: Opisthopora) of China by Nengwen Xiao Pdf

The content is classified according to the classification system of Sims and Easton. Each earthworm is described in detail from existing data sources and includes descriptions of external morphological characteristics, internal morphological characteristics, body color and distribution. This book is a useful resource for researchers and practitioners in the field of systematics, phylogeny, biodiversity, soil invertebrate zoology and ecology. Covers over 370 species of earthworms Describes the source of each kind of earthworm, their main classification features, and distribution Discusses the differences between similar earthworms Includes accompanying figures on the typical characteristics of each earthworm
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.
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.
'I thought I knew quite a bit about earthworms – until I picked up this charming little book' Nick Baker 'Many wonderful wormy tales unearthed by Coulthard' BBC Countryfile Magazine 'A gem of a book' Country Smallholding Without these little engineers of the earth, the world's soils would be barren, and our gardens and fields wouldn't be able to grow the food we need to survive. Worms recycle decaying plants, putting nutrients back into the soil; they provide a food source for wildlife; and their constant burrowing helps heavy rain soak away. Sally Coulthard's fascianting guide offers a wealth of information and practical advice about the world's msot industrious but little understood creature.
Biological Invasions Belowground: Earthworms as Invasive Species by Paul F. Hendrix Pdf
The papers in this book are based on efforts by an international group of soil ecologists to assess the biological and ecological mechanisms of earthworm invasions. They examine their geographic extent and impacts on terrestrial ecosystems, and possible means by which earthworm invasions might be mitigated. The book broadens the discussion on invasion biology and ecology to belowground systems.
