DOWNLOAD EBOOKSoil 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.

DOWNLOAD EBOOKIn aquatic ecosystems, the oligochaetes are often a major component of the community. Their relevance in sediment quality assessment is largely related to their benthic and detritivorous life habit. In this book, we aim to present the state of the art of Pollution Biology using oligochaete worms in laboratory and field studies. Future research will require the combination of a variety of methodological approaches and the integration of the resulting information, avoiding fragmented and often conflicting visions of the relationships of the species with their environment. Current approaches to ecotoxicology and bioaccumulation using ecological risk assessment provide the opportunity to relate community studies with probability of effects. This book addresses three main themes: Ecological and Field Studies using the composition and structure of oligochaete communities, Toxicology and Laboratory Studies, and Bioaccumulation and Trophic Transfer Studies. Two appendices list values of toxicological parameters (LC50, EC50) and several bioaccumulation variables (bioaccumulation factors, biological half-life, toxicokinetic coefficients, and critical body residues) for different oligochaete species. Additional information is provided on Methodological Issues and on the Taxonomy of several oligochaete families, with information on the most recent taxonomic debates. Each chapter includes a critical view, based on the authors’ experience, of a number of current issues which have been raised in the literature.

DOWNLOAD EBOOKThe book contains papers on the biology of aquatic oligochaetes and some related groups. They cover a wide range of topics including phylogeny, taxonomy, geographic distribution, freshwater and marine ecology, population dynamics, histology and ultrastructure, physiology and behaviour. The wide scope is in line with recent trends in annelid research with less emphasis on pollution studies and faunistics and a renewed interest in experimental biology using new techniques.
