Book Description
Biochemistry and Physiology of Protozoa, Volume I focuses on the chemical and physiological features of Protozoa, including nutrition, metabolism, and growth of phytoflagellates, Trypanosomidae and Bodonidae, biochemistry of ciliates and Plasmodium, and the influence of antimalarials. The selection first offers information on the biochemistry of Protozoa and phytoflagellates, including sexuality in Chlamydomonas, growth factors and chemical asepsis, descriptive chemistry and phylogenetic relationships, evolutionary aspects of photosynthesis, nutrition and biochemistry of Protozoa, and the biochemical evolution of Protozoa. The text then ponders on the nutrition of parasitic flagellates and metabolism of Trypanosomidae and Bodonidae. The publication takes a look at the nutrition of parasitic amebae, biochemistry of Plasmodium and the influence of antimalarials, and the biochemistry of ciliates in pure culture. Topics include carbon metabolism and respiration, nitrogen metabolism, antimalarial compounds and their influence on the metabolism of malarial parasites, metabolism of malarial parasites, and nutrition of the dysentery ameba, Entamoeba histolytica. The selection is a valuable reference for cytologists, geneticists, and pathologists interested in the biochemistry and physiology of protozoa.

Book Description
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.

Book Description
It is now 17 years since the junior author's book Parasitic protozoa was first published, and 13 years since it received limited revision. The study of symbiotic protozoa has meanwhile progressed, and much of the content of the earlier book has been superseded if not displaced by recent knowledge. We believe that there is still a place for an introductory textbook, conventionally arranged on a taxonomic frame work, on this most fascinating group of organisms. It should supplement (certainly not supplant) more modern treatments from different angles. A mountain looks very different if one approaches it from different sides, though a true picture of that mountain can be built up only by the laborious summation of the views provided by all approaches. The immunology and the chemotherapy of protozoal infections are subjects so complex that we do not propose to try to encompass them in this book. We mention briefly the more commonly used therapeutic compounds in the various chapters that follow, without giving details of dosage schedules. Further information on immunology and chemo therapy can be obtained from the books listed at the end of the Introduction; the information we give on chemotherapy is largely drawn from that of James & Gilles. This book can be regarded as an evolutionary descendant of the earlier "Parasitic protozoa", referred to above, extensively revised and much more fully illustrated. We hope that it will prove as useful as its predecessor appears to have been.

Book Description
Comparative Biochemistry: A Comprehensive Treatise, Volume I: Sources of Free Energy focuses on the desire to provide a sound, critical, and provocative summary of knowledge in comparative biochemistry, including thermodynamics, biological systems, oxidation, visual systems, and aerobic and anaerobic reactions of inorganic substances. The selection first offers information on the introduction to comparative biochemistry and thermodynamics of living systems. Discussions focus on comparative point of views in biology and biochemistry, classical thermodynamics, reaction rates in chemical and biological systems, and thermodynamics of open systems. The text then ponders on comparative mechanisms for fatty acid oxidation; phosphoric acid anhydrides and other energy-rich compounds; and onium compounds and their biological significance. The publication examines phototropism and phototaxis and distribution and evolution of visual systems. Topics include phototropism in plants, analysis of phototropic reaction, nature of photoreceptors, role of auxin in phototropism of plants, visual systems of vertebrates, and habitat relations. The book also tackles aerobic and anaerobic reactions of inorganic substances and comparative biochemistry of glycolysis. The selection is a dependable source of data for readers interested in the sources of free energy.

Book Description
The protozoa are an eclectic assemblage of organisms encompassing a wide range of single-celled and multiple-celled colonial organisms lacking tissue organiza tion, but exhibiting remarkably refined biological behavior. In some modern classifications, they are classified as a subkingdom among the Protista (eukary otic single-celled organisms). Although they are not considered a formal cate gory by some taxonomists and some biologists consider the name inappropriate (inferring that they are the first unicellular animals, although some photosynthe size), it is still convenient to consider this group of organisms as an informal collection under the heading of protozoa. Their cosmopolitan distribution, sig nificant ecological role in mineral recycling and enhancement of carbon flow through lower trophic levels of food webs, and remarkable cellular adaptations to enhance survival in diverse environments make them significant organisms for biological investigation. In some cases, biologists are introduced to this group in first level courses or in invertebrate zoology, but never develop a full appreciation for the diverse and biologically sophisticated characteristics of these organisms. This book is intended as a survey of broad concepts in protozoan biology with an emphasis on comparative data. The focus is on the zoological aspects of the group. Topics more closely related to plantlike characteristics, as presented in books on phycol ogy, are not considered in detail here. A sound background in modern biology and an introduction to cellular biology will be helpful in understanding Chapters 15 and 16, which include a substantial amount of information on biochemistry.

Book Description
1 Modern biologists describe protozoa as microscopic eukaryotic organ isms with a capacity for establishing themselves in almost every con ceivable habitat provided it contains moisture in some form. In 1674 at the time when Antony von Leeuwenhoek was making his first observations of 'very small animalcules' in Berkelse Mere near his home town of Delft, this concept of the ubiquity of protozoa would have been difficult to comprehend. Leeuwenhoek's curiosity later led him to examine the body fluids, gut contents and excreta of different animals and to describe 'an inconceivably great company of living animalcules, and these of divers sorts and sizes'. Here were early des criptions of parasitic protozoa, species which later came to be recog nized as Opalina, Giardia, Trichomonas and others. Following his pioneering work in the field of microscopic observation, knowledge of protozoa has accumulated at an accelerating pace. Some 30,000 living species have been identified, and an equal number of fossil species, from habitats which range from the ocean waters to the exuvial fluid of insects. The study of protozoan nutrition is a particularly interesting aspect of this expanding field of zoology. What kind of nourishment do protozoa need, how do they acqlire it, and what influence do the answers to these two questions havE on where protozoa live? The need to determine what hId of food protozoa are utilizing in their environment is desirable in al ecological studies involving micro organisms of aquatic communities.

Book Description
Updated and much expanded, the Second Edition of Parasitic Protozoa is designed to be useful to physicians, veterinarians, and research scientists concerned with diseases caused by protozoa in man, and in domestic and wild animals including fish, mollusks and insects, as well as the more commonly considered vertebrate animals. Each section contains information on disease pathogens, treatment, diagnosis, and epidemiology of the diseases caused by the various protozoans. The book is not limited to these medically-oriented subjects, but treats taxonomy, morphology, and metabolism of the organisms in such a way as to be of interest to scientists and graduate students working in the field of protozoology. The entire edition, published in ten volumes, is arranged so that subjects of common interest occupy individual volumes.

Book Description
Biology of Plant Litter Decomposition, Volume II is organized into two parts. The first part focuses on the organisms involved in plant litter decomposition, particularly, their structure and function. The second part deals with the environmental conditions under which breakdown occurs over the whole global surface. This volume separately considers terrestrial, freshwater, and marine environments. Furthermore, it describes two anthropocentric aspects: agriculture, with an emphasis on the importance of the saprophytic activity of plant pathogenic fungi, and the increasingly important composting of urban waste. This book will be invaluable to science students and instructors, as well as to biologists, botanists, marine ecologists.
