An illustrated guide to the identification of protozoa that includes over 230 high-quality colour photographs and nearly 500 detailed line drawings.
This exquisitely illustrated book is the definitive guide to the identification of protozoa. As well as over 230 high-quality colour photographs, it contains 500 detailed line drawings, showing essential features and making speedy and positive identification possible. The succinct and authoritative text is supported by extensive references. Communities of protozoa are dealt with in a separate section, which covers a range of environments and contains information on the significance of these communities as indicators of contamination and pollution. As well as being an essential teaching aid, Free-Living Freshwater Protozoa is a valuable guide for professional biologists involved with water, sewage treatment, rivers, soils and environmental management. it is also an important reference source for food science laboratories and public health and regulatory bodies. Free-Living Freshwater Protozoa includes: Collection, examination and recording of protozoa Classification Identification — using the highly illustrated key with supporting text and references Protozoan communities — covering a range of man-made and natural environments Glossary of terms Extensive bibliography and reference lists From the Reviews: ‘… The photomicrographs are generally of excellent quality, and these, with the equally excellent line drawings and complete descriptions, make for a very easy-to-use key. This is about the best reference one could have, short of an actual, living specimen … This is not a specialist book and can be easily used by amateurs; but it should also prove a valuable guide to professional biologists involved with water, sewage works, rivers, soils, environmental management, food science, and public health; it would, in addition, serve as a dandy teaching aid for classroom use, as well as for self-study.’ — The Microscope
Protozoa are active components of the soil microfauna. For example, they may stimulate bacterial metabolism and some fungal metabolites can lyse protozoa. They may be predators of bacteria and hence have a role in biological control. Their presence in groundwaters can be used as an indicator of pollution, while they are also being used to treat sewage in the activated-sludge and reed-bed processes. They are believed to be major secondary decomposers in soil and increased knowledge about these microorganisms is important to sustain soil fertility and food production. This book is the first in English for 65 years devoted entirely to soil protozoology. It is written by experienced microbiologists and should be of interest to protozoologists, other microbiologists, and soil scientists.
This long-awaited book about non-pollen palynomorphs (NPPs) aims to cover gaps in our knowledge of these abundant but understudied palynological remains. NPPs, such as fungal spores, testate amoebae, dinoflagellate cysts, acritarchs and animal remains, are routinely recovered from palynological preparations of marine or terrestrial material, from Proterozoic to recent geological times. This book gives the reader a comprehensive overview of the different types of NPPs, with examples from diverse time periods and environments. It provides guidance on sample preparation to maximize the recovery of these NPPs, detailed information on their diversity and ecological affinity, clarification on the nomenclature and demonstrates their value as environmental indicators. This volume will become the reference guide for any student, academic or practitioner interested in everything else in their palynological preparations.
Protists are by far the most diverse and abundant eukaryotes in soils. Nevertheless, very little is known about individual representatives, the diversity and community composition and ecological functioning of these important organisms. For instance, soil protists are commonly lumped into a single functional unit, i.e. bacterivores. This work tackles missing knowledge gaps on soil protists and common misconceptions using multi-methodological approaches including cultivation, microcosm experiments and environmental sequencing. In a first part, several new species and genera of amoeboid protists are described showing their immense unknown diversity. In the second part, the enormous complexity of soil protists communities is highlighted using cultivation- and sequence-based approaches. In the third part, the present of diverse mycophagous and nematophagous protists are shown in functional studies on cultivated taxa and their environmental importance supported by sequence-based approaches. This work is just a start for a promising future of soil Protistology that is likely to find other important roles of these diverse organisms.
This well-referenced, inquiry-driven text presents an up-to-date and comprehensive understanding of the emerging field of environmental microbiology. Coherent and comprehensive treatment of the dynamic, emerging field of environmental microbiology Emphasis on real-world habitats and selective pressures experienced by naturally occurring microorganisms Case studies and “Science and the Citizen” features relate issues in the public’s mind to the underlying science Unique emphasis on current methodologies and strategies for conducting environmental microbiological research, including methods, logic, and data interpretation
