The second revised edition of this manual aims at providing students and less experienced professional aquatic biologists with a key to identify some to the more commonly encountered aquatic freshwater algal genera of the United States. In response to reviewers comments, a brief section on diatoms, a section providing a number of possible of dispositions of the genera into a taxonomic hierarchy and a brief glossary of technical terms have been added in this revised edition. A number of nomenclatural changes is reflected as well.Keys, representative illustrations and general ecological notes are provided for some 300 genera, excluding the diatoms (except for a brief section on them). The keys are based on features observable in freshly collected material.

Freshwater Algae: Identification and Use as Bioindicators provides a comprehensive guide to temperate freshwater algae, with additional information on key species in relation to environmental characteristics and implications for aquatic management. The book uniquely combines practical material on techniques and water quality management with basic algal taxonomy and the role of algae as bioindicators. Freshwater Algae: Identification and Use as Bioindicators is divided into two parts. Part I describes techniques for the sampling, measuring and observation of algae and then looks at the role of algae as bioindicators and the implications for aquatic management. Part II provides the identification of major genera and 250 important species. Well illustrated with numerous original illustrations and photographs, this reference work is essential reading for all practitioners and researchers concerned with assessing and managing the aquatic environment.
