Nematodes are the most numerous metazoans in aquatic sediments. The majority of conducted studies on these aquatic forms focus mainly on those in marine and estuarine habitats. Nematodes from inland water bodies have been relatively forgotten or ignored.

This section of the Handbook of Zoology is intended as a comprehensive and exhaustive account of the biology of the taxa Gastrotricha, Nematoda, Nematomorpha, Priapulida, Kinorhyncha, Loricifera, Gnathostomulida, Micrognathozoa, Rotifera, Seisonida and Acanthocephala, covering all relevant topics such as morphology, ecology, phylogeny and diversity. The series is intended to be a detailed and up-to-date account of these taxa. As was the case with the first edition, the Handbook is intended to serve as a reliable resource for decades. Many of the taxa of this volume are comparatively unknown to many biologists, despite their diversity and importance for example in meiofaunal communities (Gastrotricha, Rotifera, Gnathostomulida), their fascinating recent discoveries (Loricifera and Micrognathozoa), their importance as parasites (many nematodes, Nematomorpha, Acanthocephala) and their importance for evolutionary questions (e.g. Priapulida, Gastrotricha). The groups covered range from those poor in species (such as Micrognathozoa with 2 known species) to the species-rich and diverse Nematoda and their ca. 20.000 described species. While each taxon is covered by one chapter, nematodes are treated in several chapters dedicated to their structural, taxonomic and ecological diversity.

Nematode worms - living as parasites of virtually every species of plant and animal, and inhabiting terrestrial, fresh water, and marine habitats - exert a powerful effect on the Earth's biosphere. While nearly 20,000 species have been described, it is estimated that 80,000 to 1,000,000 species of nematodes actually exist. Best known as parasitic disease carriers and crop destroyers, the more abundant free-living (nonparasitic) nematode species play instead a valuable ecological role.

The Biology of Nematodes synthesizes knowledge of the biology of free-living, plant-parasitic, and animal-parasitic nematodes. Contributed works by recognized researchers apply groundbreaking molecular techniques, many of which resulted from work on Caenorhabditis elegans, toward new approaches to the study of nematode worms. Topics covered include: ̈ Systematics and phylogeny ̈ Neuromuscular physiology ̈ Locomotion ̈ Sense organs ̈ Behavior ̈ Aging ̈ The nematode genome ̈ Survival strategies ̈ Immunology ̈ Epidemiology ̈ Structure and organization ̈ Gametes and fertilization ̈ Development ̈ Feeding, digestion, and metabolism

The volume deals with morphology, taxonomy and systematics of entomopathogenic nematodes (EPN) in the families Steinernematidae and Heterorhabditidae and bacteria associated with these nematodes. In the first part, history, taxonomic status, family and genus definitions of EPN are mentioned. In the second part, all useful aspects of morphology and methodology of EPN are mentioned with illustrations and SEM photographs and instructions on how to make the measurements, and how to use them in taxonomic work. A polychotomous key with SEM photographs and illustrations is provided. In the third part, full descriptions of all species are presented with latest information about each species. In the fourth part, molecular and phylogenetic methods for working with EPN are presented, including the latest information and instructions on how to use molecular data in taxonomic work. In the last part, bacteria associated with this group of nematodes are discussed in the context of the latest information about methodology, biology and taxon.

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.
