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.

Ecology of Protozoa

Ecology of Protozoa PDF Author: Genoveva F. Esteban
Publisher: Springer Nature
ISBN: 3030599795
Category : Science
Languages : en
Pages : 188

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.

Lysosomes

Lysosomes PDF Author: Eric Holtzman
Publisher: Springer Science & Business Media
ISBN: 1489925406
Category : Science
Languages : en
Pages : 454

Book Description
In 1976 I wrote a monograph on lysosomes (Lysosomes: A Survey, Springer Verlag, Vienna) that was intended as an up-to-date, comprehensive survey. Whatever success I may have achieved then in fulfilling that intention, even the effort now would be foolhardy. The literature has grown so rapidly in the past decade that I certainly could not even read all of the essential papers, let alone understand and analyze them. My goal here, therefore, is simply to introduce the major features of lysosomes at a level I hope will be useful both to I;ldvanced students and to researchers interested in obtaining a broad background. This is in keeping with the design of the Cellular Organelles series: the series is more a set of advanced texts than of review monographs. This design carries with it the decision not to support each point by refer ences to the original literature. I apologize for the injustice involved in such a decision but feel that in any event it would be impossibly unwieldy to cite, adequately and in a balanced manner, the contributions of the vast network of researchers responsible for the information upon which I draw.

Microbial Ecology of Activated Sludge

Microbial Ecology of Activated Sludge PDF Author: Robert Seviour
Publisher: IWA Publishing
ISBN: 1843390329
Category : Science
Languages : en
Pages : 685

Book Description
Microbial Ecology of Activated Sludge, written for both microbiologists and engineers, critically reviews our current understanding of the microbiology of activated sludge, the most commonly used process for treating both domestic and industrial wastes. The contributors are all internationally recognized as leading research workers in activated sludge microbiology, and all have made valuable contributions to our present understanding of the process. The book pays particular attention to how the application of molecular methods has changed our perceptions of the identity of the filamentous bacteria causing the operational disorders of bulking and foaming, and the bacteria responsible for nitrification and denitrification and phosphorus accumulation in nutrient removal processes. Special attention is given to how it is now becoming possible to relate the composition of the community of microbes present in activated sludge, and the in situ function of individual populations there, and how such information might be used to manage and control these systems better. Detailed descriptions of some of these molecular methods are provided to allow newcomers to this field of study an opportunity to apply them in their research. Comprehensive descriptions of organisms of interest and importance are also given, together with high quality photos of activated sludge microbes. Activated sludge processes have been used globally for nearly 100 years, and yet we still know very little of how they work. In the past 15 years the advent of molecular culture independent methods of study have provided tools enabling microbiologists to understand which organisms are present in activated sludge, and critically, what they might be doing there. Microbial Ecology of Activated Sludge will be the first book available to deal comprehensively with the very exciting new information from applying these methods, and their impact on how we now view microbiologically mediated processes taking place there. As such it will be essential reading for microbial ecologists, environmental biotechnologists and engineers involved in designing and managing these plants. It will also be suitable for postgraduate students working in this field.

The Biology of Paramecium

The Biology of Paramecium PDF Author: R. Wichterman
Publisher: Springer Science & Business Media
ISBN: 1475703724
Category : Medical
Languages : en
Pages : 614

Book Description
This completely revised, updated, and expanded edition has been neces sitated by the many important newer discoveries that have been made since the publication of the first edition. That volume contained almost 2000 references from the 1600s to 1953. Since then and after an extensive search, I have accumulated some 3800 additional titles from the world's literature on Paramecium. After certain titles that largely represented abstracts and preliminary reports that were followed by full research papers were eliminated, approximately 4400 full titles from the 1600s to the present were selected for inclusion in this edition. Most of the titles in the Bibliography are the more recent ones beginning with 1953. I consider the Bibliography an important part of the book: A good title of a paper in a journal is a minature abstract of its contents. Thus, the reader who may be interested in obtaining additional information not found in the book may refer directly to the original source. A cursory examination of the Bibliography will reveal that parame cium research has extended into all branches of biology, including bio chemistry and biophysics. Like other areas of science, paramecium research has become highly specialized and fragmented. I have attempted to organize and present the basic information in one book. Because of space limitations, some items may have been dealt with briefly. It is in such instances that the Bibliography will be found to be invaluable.

Protozoan Parasites of Fishes

Protozoan Parasites of Fishes PDF Author: J. Lom
Publisher:
ISBN:
Category : Medical
Languages : en
Pages : 336

Book Description
Based on twenty years of research experience, this unique, large format volume presents an up-to-date treatment of the biology, relation to the host, taxonomy and diagnostic features of protozoan parasites infecting fishes. By presenting definitions of all 151 genera, keys for the determination of all main groups of fish protozoa, copious illustrations and half-tone plates, and details on the technique of investigation, the book makes it possible to determine all protozoan parasites of fishes down to generic level. In each genus, all important pathogenic species are dealt with, special attention being paid to their pathogenic action, and these are well documented by photomicrographs. A wide range of information is given on host-parasite relations, including data on pathogenicity of separate groups and species; and a host-parasite checklist enables a quick orientation on protozoa that may be encountered in one hundred economically important fish species. In addition to the to the true protozoan phyla, an appendix lists a few organisms of uncertain position with alleged or possible relation to protozoa; altogether, 561 species are described. This book is the first of its kind and should be invaluable reading for all fish parasitologists, fisheries biologists, aquaculturists and all others interested in protozoan parasites of fishes.
