Mass Production of Beneficial Organisms by Juan A. Morales-Ramos,M. Guadalupe Rojas,David I. Shapiro-Ilan Pdf

Mass Production of Beneficial Organisms: Invertebrates and Entomopathogens, Second Edition explores the latest advancements and technologies for large-scale rearing and manipulation of natural enemies while presenting ways of improving success rate, predictability of biological control procedures, and demonstrating their safe and effective use. Organized into three sections, Parasitoids and Predators, Pathogens, and Invertebrates for Other Applications, this second edition contains important new information on production technology of predatory mites and hymenopteran parasitoids for biological control, application of insects in the food industry and production methods of insects for feed and food, and production of bumble bees for pollination.Beneficial organisms include not only insect predators and parasitoids, but also mite predators, nematodes, fungi, bacteria and viruses. In the past two decades, tremendous advances have been achieved in developing technology for producing these organisms. Despite that and the globally growing research and interest in biological control and biotechnology applications, commercialization of these technologies is still in progress. This is an essential reference and teaching tool for researchers in developed and developing countries working to produce “natural enemies in biological control and integrated pest management programs. Highlights the most advanced and current techniques for mass production of beneficial organisms and methods of evaluation and quality assessment Presents methods for developing artificial diets and reviews the evaluation and assurance of the quality of mass-produced arthropods Provides an outlook of the growing industry of insects as food and feed and describes methods for mass producing the most important insect species used as animal food and food ingredients

Biology of Earthworms by Ayten Karaca Pdf

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.

The Geographical Distribution of Animals by Alfred Russel Wallace Pdf

"Wallace, together with Darwin was the founder of modern evolutionary theory, and when Darwin received Wallace's paper of 1858 (a year before the publication of the Origin of Species), he wrote to Lyell "All my originality, whatever it may amount to, will be smashed"."I never saw a more striking coincidence.Your words (referring to Lyell's earlier warnings that Darwin might be anticipated) have come true with a vengeance." In 1858 Wallace was already preparing an announcement of an importent zoogeographical discovery, which proposed a boundary line dividing the archipelago of Indo-Malayan and Australian zoological regions. The culmination of Wallace's approach was achieved in his monumental two-volume "The geographical Distribution." and it is a pioneer-work in zoogeography."--Abebooks website.

Soil Invertebrates by Nico M. van Straalen Pdf

Soil invertebrates make up diverse communities living in soil pores and on the soil surface, digging burrows and tunnels, processing organic matter and interacting with microbes. Soil is also a habitat of growing concern as many human activities cause soil degradation. This book documents the evolutionary history of soil invertebrates and their multitude of adaptations. Soil invertebrates live in a twilight zone: some have gone down to seek stability, constancy and rest, others have gone up and faced environmental variation, heat, cold and activity. And it all happens in a few decimetres, millimetres sometimes. Check out the wonderful life below ground in this book.

Earthworm Ecology by Clive A. Edwards Pdf

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.

The Physiology of Earthworms by M. S. Laverack Pdf

The Physiology of Earthworms focuses on the three species of earthworms — Liimbricus terrestris, Eisenta foetida, and Allolobophora longa. Other earthworms or oligochaetes such as the fresh-water species are briefly mentioned. The topics covered include the biochemical architecture; digestion and metabolism; calciferous glands; axial field; nitrogenous excretion; water relations; respiration; physiology of regeneration; neurosecretion; nervous system; and behavior of oligochaetes. This book is a good source of information for biology students and researchers conducting work on earthworms and its different species.

Variation and Evolution in Plants and Microorganisms by National Academy of Sciences Pdf

"The present book is intended as a progress report on [the] synthetic approach to evolution as it applies to the plant kingdom." With this simple statement, G. Ledyard Stebbins formulated the objectives of Variation and Evolution in Plants, published in 1950, setting forth for plants what became known as the "synthetic theory of evolution" or "the modern synthesis." The pervading conceit of the book was the molding of Darwin's evolution by natural selection within the framework of rapidly advancing genetic knowledge. At the time, Variation and Evolution in Plants significantly extended the scope of the science of plants. Plants, with their unique genetic, physiological, and evolutionary features, had all but been left completely out of the synthesis until that point. Fifty years later, the National Academy of Sciences convened a colloquium to update the advances made by Stebbins. This collection of 17 papers marks the 50th anniversary of the publication of Stebbins' classic. Organized into five sections, the book covers: early evolution and the origin of cells, virus and bacterial models, protoctist models, population variation, and trends and patterns in plant evolution.

Earthworm Ecology by J. Satchell Pdf

'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.
