Nematodes are the most wide spread multicellular animals in nature and analysis of nematodes in terrestrial, freshwater and marine environments as well as their role and function in ecosystems, can be used for environmental monitoring. Compared to other organisms, they offer the greatest potential as bioindicators and can be used to study gene expression in relation to environmental challenges, to monitor changing impacts on the environment and in laboratory ecotoxicity tests. This volume addresses classical and molecular approaches to nematode community analysis, the contemporary field of nematodes as biosensors, as well as genomic aspects of nematode bioindicators. In addition, the case studies stress the importance of these bioindicators and demonstrate the commercial potential of these technologies.

This book contains 22 chapters on various aspects of freshwater nematode ecology and taxonomy. Subjects covered include the techniques for processing freshwater nematodes, the composition and distribution of free living freshwater nematodes, their abundance, biomass and diversity, the production of freshwater nematodes, their feeding ecology, patterns in size structure of freshwater nematode communities, different nematode habitats, and computation and application of nematode community indices. It provides descriptions with figures of each taxon at the genus level and above to currently valid genera. For every genus, a complete list of species, with an emphasis on biogeography, is given for primarily freshwater taxa and a list of only those species reported from freshwater bodies is given for the genera that are considered primarily non-freshwater. This book is intended to provide a useful reference to students, beginners and established researchers in the field of freshwater nematology, benthologists, invertebrate biologists, limnologists, ecologists, microbiologists and soil biologists.

The offered volume intends to review the biological control theme of phytonematodes from several prospects: ecological; applicative as well as commercial state of the art; understanding the mode-of-action of various biocontrol systems; interaction between the plant host, nematodes’ surface and microorganism’s; candidates for biocontrol; extrapolation of the wide knowledge existed in another systems for understanding biocontrol processes: C. elegans as a model and lessons from other natural systems; and exploiting advanced genomic tools to promote understanding biocontrol processes and thereafter improve specific biological control agents.

These chapters provide up-to-date information on nematophagous fungi, particularly those of the Orbiliaceae in Ascomycota, whose asexual states produce nematode-trapping devices. The authors consider fungal-nematode interactions, fossil fungi, the biodiversity, ecology and geographical distribution of nematode-trapping fungi, and their potential use in biocontrol of nematodes, all in detail. Nematode-trapping fungi with adhesive or mechanical hyphal traps are the main focus of this book which begins with an overview of the data on nematode-trapping fungi, including their taxonomy, phylogeny and evolution. Subsequent chapters expand upon the methods and techniques used to study these fascinating fungi. Keys for genera of Arthrobotrys, Drechslerella and Dactylellina, which include all reported species of predatory orbiliaceous fungi are presented and numerous species from these genera are morphologically described and illustrated. The ecology of nematode-trapping fungi is expertly presented: their occurrence and habitats, their geographical and seasonal distribution and the effects of soil conditions and nematode density on their distribution all feature amongst the relevant themes. Further chapters examine the use of nematode-trapping fungi in biological control and the authors consider nematicidal activities in detail, exploring the many compounds from fungi that feature in nematicidal activities and of course useful paths for further study on this topic. This is a highly informative and carefully presented book, providing scientific insight for scholars with an interest in fungi and in biological control of nematodes.

The preface of a book often provides a convenient place in which the author can tender his apologies for any inadequacies and affords him the facility to excuse himself by reminding the reader that his art is long but life, or at least the portion of it in which he has the opportunity for writing books, is short. I, too, am deeply conscious that I have undertaken a task which I could not hope to complete to my own satisfaction but I offer, in self defence, the observation that, inadequate though it is, there is no other book extant, so far as I am aware, which provides the information contained herein within the covers of a single volume. Often during the last decade, in discharging my responsibilities for the environmental aspects of the water authority's operations and works, I should have been deeply grateful to have had access to a compendium such as this. The lack of a convenient source of data made me aware of the need which I have attempted to fill and in doing so I have drawn on my experiences of the kinds of problem which are presented to biologists in the water industry. The maxim 'half a loaf is better than none' seems particularly apt in this context.
