General Editor: Peter Calow, Department of Zoology, University of Sheffield, England The main aim of this series will be to illustrate and to explain the way organisms 'make a living' in nature. At the heart of this - their func tional biology - is the way organisms acquire and then make use of resources in metabolism, movement, growth, reproduction, and so on. These processes will form the fundamental framework of all the books in the series. Each book will concentrate on a particular taxon (species, family, class or even phylum) and will bring together information on the form, physiology, ecology and evolutionary biology of the group. The aim will be not only to describe how organisms work, but also to consider why they have come to work in that way. By concentrating on taxa which are well known, it is hoped that the series will not only illustrate the success of selection, but also show the constraints imposed upon it by the physiological, morphological and developmental limita tions of the groups. Another important feature of the series will be its organismic orienta tion. Each book will emphasise the importance of functional integra tion in the day-to-day lives and the evolution of organisms. This is crucial since, though it may be true that organisms can be considered as collections of gene-determined traits, they nevertheless interact with their environment as integrated wholes and it is in this context that individual traits have been subjected to natural selection and have evolved.

This book emphasises the important role that protozoa play in many natural ecosystems. To shed new light on their individual adaptive skills, the respective chapters examine the ecology and functional biology of this diverse group of eukaryotic microbes. Protozoa are well-established model organisms that exemplify many general problems in population ecology and community ecology, as well as evolutionary biology. Their particular characteristics, like large population sizes, life cycles and motile sensory behaviour, have a profound impact on their survival, distribution, and interaction with other species. Thus, readers will also be introduced to protozoan habitats in a broad range of environments. Even though this group of unicellular organisms is highly diverse, the authors focus on shared ecological patterns. Students and scientists working in the areas of eukaryotic microbiology and ecology will appreciate this updated and revised 2nd Edition as a valuable reference guide to the “lifestyles” of protozoa.

Protozoa may be found in almost every aquatic habitat, each containing dozens of species. The diversity can provide invaluable insights into the nature of the habitat and can be used as an indicator of environmental change, pollution and contamination. This colour guide makes the identification of individual protozoa easily accessible to students and professionals and provides information on protozoan communities found in different environments by means of a wealth of colour photomicrographs supported by original and detailed line drawings and concise text.

Protozoa and Human Disease is a textbook on medically important protozoa and the diseases they cause for advanced undergraduate students, graduate students, and professionals. It combines a taxonomic and medical approach and is therefore suitable for a parasitology, microbiology, medical, and public health readership. In addition to the basics such as morphological features, life cycles, and the clinical manifestations of the diseases, topics like the molecular and immunological basis of pathogenesis, metabolic pathways, specialized subcellular structures, ecology of disease transmission, antigenic variation, and molecular epidemiology are discussed for many of the protozoan pathogens. At the end of the book is an extensive glos
