Biology of Earthworms
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.
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...

Vermiculture Technology
Exploring the dramatic growth and changes in the field of vermicomposting since 1988, this comprehensive review assesses the advancements made in government-funded projects in the U.S. and UK. It discusses outdoor and indoor windrows, container systems, wedge systems, and low labor-requirements. It also examines fully-automated continuous flow vermicomposting reactor systems that can process more than 1000 tons of organic wastes per reactor. The book highlights the science and biology behind the use and efficacy of vermicomposting and details the technology of the past, present, and future.
Culture and Utilization of Live Food Organisms for Aquahatcheries
In today's world, food scarcity and food security are significant global concerns, with 811 million people suffering from hunger and 3 billion individuals unable to afford healthy diets. This book discusses fisheries and aquaculture as crucial contributors to nutritional security and the need for sustainable practices to meet the growing demand. The subject matter of this book covers: Recycling of Waste Through Tubifex Culture and Used as Live Food in Aquahatcheries Culture Techniques of Daphnia Mosquito Larval Control Through the Larvivorous Fish Chlorella Live Food: Cultivation and Applications Print edition not for sale in South Asia (India, Sri Lanka, Nepal, Bangladesh, Pakistan and Bhutan)
