The third edition of The Ciliated Protozoa thoroughly documents the progress in our understanding of the evolutionary diversification of these widely distributed eukaryotic microorganisms. The Glossary is considerably revised and expanded, serving as an illustrated subject index of more than 700 terms. An introduction to the phylum is followed by chapters on the 11 classes. The book also contains a major chapter entitled The Ciliate Taxa. As an additional feature, all figures are available electronically for free viewing on the book's homepage at www.springer.com/978-1-4020-8238-2, under Additional Information.
