Freshwater Algae of North America, Second Edition is an authoritative and practical treatise on the classification, biodiversity, and ecology of all known genera of freshwater algae from North America. The book provides essential taxonomic and ecological information about one of the most diverse and ubiquitous groups of organisms on earth. Scientists from many disciplines, from evolutionary biology to DNA bar-coding to ecosystem management, rely on up-to-date information on the biology and classification of algae. This book brings together experts on all the groups of algae that occur in fresh waters (also soils, snow, and extreme inland environments), providing all of this comprehensive information in a single volume. In the decade since the first edition, there has been an explosion of new information on the classification, ecology, and biogeography of many groups of algae, with the use of molecular techniques and renewed interest in biological diversity. Accordingly, this new edition covers updated classification information of most algal groups and the reassignment of many genera and species, as well as new research on harmful algal blooms.
