Earthworms

Biology and Ecology of Earthworms is established as a key valuable text for students of agriculture, soil science, and soil invertebrate zoology and ecology. This is the 4th Edition of the popular textbook which reviews all aspects of earthworm biology and ecology. The book has been fully revised and updated throughout. Particular changes include: new treatments of earthworm taxonomy, diversity, migration and geographical distribution; interactions between earthworms and other soil organisms, especially microorganisms and soil-borne pests and diseases; as well as the importance of earthworms in organic waste management.

This volume represents the current trend of research in ecology and biology of earthworms.

Bioavailability is a complicated issue. In this thesis, Tjalling Jager discusses how organic chemicals are taken up by earthworms, and to what extent. Earthworms are essential for soil fertility, as well as important dietary items for a range of predators. A "mechanistic" approach is followed: starting with the theory, translating theory into mathematical models, and experiments to verify the model predictions.

Cement, Earthworms, and Cheese Factories examines the ways in which religion and community development are closely intertwined in a rural part of contemporary Latin America. Using historical, documentary, and ethnographic data collected over more than a decade as an aid worker and as a researcher in central Ecuador, Jill DeTemple examines the forces that have led to this entanglement of religion and development and the ways in which rural Ecuadorians, as well as development and religious personnel, negotiate these complicated relationships.
