Soil Invertebrates
"Soil invertebrates consist of a great variety of body plans and life-forms, since about every phylum of the animal kingdom has at least some representatives in the soil, while some are almost exclusively soil-living. All soil invertebrates descend from originally marine ancestors that have undergone many independent terrestrializations. In addition, several lineages that became fully terrestrial in their later evolution have adopted a secondary soil-living life-style. Upon all these life-forms, the soil environment has imposed similar conditions relating to space, humidity, temperature gradients and microbial communities. As a consequence we see many similar adaptations, both in reproductive biology and life-history, but also in physiology and molecular responses. The soil invertebrate community is an example par excellence of convergent and parallel evolution"--
Impact of Agricultural Practices on Biodiversity of Soil Invertebrates
Soil fauna plays a key role in many soil functions, such as organic matter decomposition, humus formation, and nutrient release, modifying soil structure, and improving its fertility. Soil invertebrates play key roles in determining soil suitability for agricultural production and realizing sustainable farming systems. They include an enormous diversity of arthropods, nematodes, and earthworms. However, this fauna suffers from the impact of agricultural activities with implications for the capacity of soil to maintain its fertility and provide ecosystem services. Some agricultural practices may create crucial soil habitat changes, with consequences for invertebrate biodiversity. In the few l...
Soil Invertebrates
This book places the biodiversity of soil invertebrates in an evolutionary framework, showing the various adaptations to the soil environment. Species radiations are discussed for each of the terrestrializations leading to a lineage of soil invertebrates. Phylogenetic analyses, now becoming available for most of these groups thanks to DNA sequencing, show monophyly of complete soil-living groups in some cases and multiple independent soil adaptations in others. The book includes many classical methods of soil animal enumeration and community surveys developed in the 1970s, which can now be supplemented by physiological and molecular study techniques.
Handbook of Soil Invertebrate Toxicity Tests
A comprehensive user guide to toxicity testing which provides readily accessible information on the results of terrestrial invertebrate testing. Presenting guidelines for the application of new test systems for soil ecotoxicity testing, this unique book also includes standard operating procedures and specialist protocols.
Soil Invertebrates
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.
Grassland Invertebrates
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 t...
Studying Invertebrates
Studying invertebrates is a comprehensive guide to designing and carrying out ecological investigations, especially those involving sampling invertebrates. A highly practical guide to fieldwork, statistical testing and interpretation. The book introduces ways of designing and analysing experiments so that complex situations can be described and summarised, comparisons made, and interactions between organisms and their environment examined objectively. This digital reprint replaces ISBN 0-85546-313-9. First published in 2003. Editors' preface The books in this series are designed to encourage readers to undertake their own studies of natural history. Each one describes some relevant technique...

Forest Ecosystems
"Fresh, exciting, and more comprehensive than many other texts. Perry introduces a whole new view of forest ecosystems. This will challenge, stimulate, and redefine current understanding and management." -- Michael Amaranthus, U.S. Forest Service
