Earthworm Ecology
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.
Biology and Ecology of Earthworms
Describes earthworm community ecology, interactions between earthworms and microorganisms and the importance of earthworms in environmental management
Earthworm Ecology
'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 earthwo...
Grassland Invertebrates
Grasslands comprise more than a quarter of the Earth's land surface. In addition to supporting a wide range of vertebrates such as domestic livestock and a variety of games species, grassland is the natural habitat for a wide range of invertebrate species, and this book considers those which occur in grassland and their impact on soil fertility and herbage growth. It describes grassland as a habitat for invertebrates, the groups which occur there and their abudance. An extensive literature on grassland invertebrates scattered through numerous scientific journals and reports is drawn on in an attempt to develop an overview. In the opening chapter the major grassland types are considered and t...
Biological Husbandry
Biological Husbandry: A Scientific Approach to Organic Farming covers a proceeding of a symposium organized by International Institute of Biological Husbandry on August 26-30, 1980 at Wye College in London, United Kingdom. Said symposium aims to promote the scientific development of biological or organic agriculture. The text covers topics such as the assessment of conventional, biological, and integrated agriculture; soil use in temperate climates, organic matter cycles in tropical soils, and plant-microbial interactions; biological pest control, the importance of chemical agents and biotechnology in biological husbandry, and allelochemicals in the future of agriculture. The book is recommended for biologists and agriculturists who would like to know more about the studies in biological husbandry and its implications in the field.

Fauna in Soil Ecosystems
Offers an integrated presentation of the microbial, agronomic and recycling aspects of soil faunal potentials, emphasizing agricultural ecosystems and furnishing methods for modelling food webs. The text covers morphology, reproduction, abundances, basic requirements, competition, predation, parasitism, nutrient cycling and phytopathological intera
Advances in Ecological Research
Jarvis and McNaughton provide a cogent example of the impact of physiological studies in ecology. The study of transpiration is of basic importance in botany and their paper shows how the often conflicting conclusions reached by physiological ecologists and micrometeorologists may be reconciled. Courtney's analysis of Pereid butterfly ecology looks at the various evolutionary strategies adopted by the butterflies, their food plants and their predators and parasites. Franklin and his colleagues have distilled years of research on the decomposition of woody debris into a comprehensive treatment of both the nature and importance of this process in a variety of environments. Vogt and her colleag...
