The Handbook of Histopathological Practices in Aquatic Environments: Guide to Histology for Environmental Toxicology offers readers in aquatic biology and other water-based environmental sciences a comprehensive resource on histopathology, which is a key tool in the growing field of ecotoxicology. This work brings together the necessary knowledge, from sample preparation, to trait identification, and scoring and data treatment. Furthermore, with examples from several groups of organisms (from worms to fish), these practices can be applied across a wide array of aquatic ecosystems. This book provides a step-by-step approach to solving the questions researchers encounter in aquatic biology and related fields. - Offers examples from a broad range of aquatic organisms, replacing sparse, dispersed and often aged literature - Covers a variety of organisms, including hard to find, non-commercial and non-model species - Provides an in-depth understanding of how and why techniques are used, as opposed to just a list of procedures - Combines, in a single work, everything from sample handling to scoring
