The Handbook of Histopathological Practices in Aquatic Enviroments 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 all the necessary knowledge for the aquatic environmental scientist, from sample preparation to essential trait identification, scoring and data treatment. Furthermore, with examples from several groups of organisms (from worms to fish), it can be applied across a wide array of aquatic ecosystems, providing a step by step approach to solving the everyday questions of newcomers and experienced researchers 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 often hard to find non-commercial and non-model species Provides an indepth understanding of how and why techniques are used, as opposed to just a list of procedures Combines into a single work everything from sample handling to scoring.
