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.

Soil Biology brings together the microbiological, botanical, and zoological aspects of soil biology. Leading specialists provide critical reviews and assessments of their particular branches of soil biology, paying particular attention to functional aspects and biotic interrelationships whenever possible. This volume is organized into 17 chapters and begins with an overview of the soil system, emphasizing the system components including the mineral fraction, organic matter, soil moisture, and soil atmosphere. The next chapters focus on microorganisms present in the soil, along with their effects on plant roots. The book also discusses the soil algae, including how algae are affected by physical and chemical environments and their interrelations with other organisms. The remaining chapters look at other organisms that inhabit the soil, including Arthropoda, Collembola, and Mollusca, as well as the probable effects of inhibiting substances upon the biology of soil microorganisms. The final chapters explain the decomposition of organic matter in the soil and the effects of synthetic chemicals on soil microorganisms. This book is a valuable resource for soil biologists and research workers in fields such as botany, agriculture, zoology, and microbiology.

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 the features which influence the distribution and abudance of the invertebrates which inhabit them are discussed. Next the major taxonomic groups are reviewed in turn, with a brief account of their biology and ecology and of their ecosystem role. Some general features of grassland invertebrate communities are then described and teh factors which influence th epopulation densities of their constituent species are considered. Particular attentionm is given to the ways in which populations are influenced by management practices. The final and largest chapterdeals with the various ways in which invertebrates influence important grassland processes through ingestion of organic matter, interaction with injurious species is considered, with particular emphasis on the potential for achieving this through manipulating grassland management practices.

In the past fifteen years there has been considerable interest in neural circuits that initiate behavior patterns. For many types of behaviors, this involves decision-making circuits whose primary elements are neither purely sensory nor motor, but represent a higher order of neural pro cessing. Of the large number of studies on such systems, analyses of startle circuits compose a major portion, and have been carried out on systems found throughout the animal kingdom. Startle has been an im portant model because of the reliability of the behavioral act for laboratory study and the accessibility of the underlying neural circuitry. However, probably because of the breadth of the subject, this material has never been reviewed in a comprehensive way that presents the elements com mon to startle circuits in the different animal systems in which they occur. This book presents a diversity of approaches based on a broad back ground of animal groups ranging from the earliest nervous systems in cnidarians to the most recently evolved and advanced in mammals. The behaviors themselves are all short latency, fast motor acts, when consid ered on the time scale of the organism, and involve avoidance or evasion, although in some cases we do not yet completely understand their natural role. These behaviors occur in response to stimuli that have sudden or unexpected onset.
