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 is a comprehensive treatise on meiobenthology, the science of small animals which live, often disregarded even by zoologists, in huge numbers in all aquatic sediments. Covering all the scientific literature on the subject, particular emphasis is placed on ecological and systematic aspects. After a survey of the biotope conditions and important methods, the animals are introduced in a systematic account. This is followed by a report on the meiobenthos in relevant biotopes. The book concludes with an analysis of the productive role and the position of meiofauna in the food web and perspectives for future research.
