Dorylaims are probably the most diverse order of nematodes and are often an abundant component of the fauna in soils and freshwater habitats. As a result of their widespread distribution and many different feeding habits, they are considered as good bio-indicators of environmental quality and soil health. Their usefulness in this regard is only impeded by practical difficulties related to the accurate identification of the members of such a large and complex group. In this volume, Professor Reyes Peña-Santiago gives a detailed morphology of the dorylaims and provides a thorough overview of their feeding behaviour, reproduction, ecology, and diversity. You will learn what dorylaims are like and how they live, making this book an invaluable tool for nematologists, ecologists and other scientists who wish to embark on an in-depth study of the members of this fascinating group.
