Book Description
Antarctica, a vast land remote from the other continents and still the least known of them all, provides a unique international laboratory for science. Despite the costs, a growing number of countries are supporting basic scientific research on the continent and in its surrounding seas. Our knowledge of life in this extreme environment, although limited, suggests that it is a key environment for many areas of science. Potential economic developments for food and minerals as well as increasing political complications might jeopardise the present scientific accord in the future. Now is the time to take stock: what do we know about Antarctic ecology? What are the threats and how can they be met? In this volume Antarctic scientists from six countries write about the Antarctic ecosystem.

Book Description
This is the second book of a series treating the hypotrichs, a major part of the spirotrichous ciliates. It summarises 230 years of morphological, morphogenetic, faunistic, and ecological data, heretofore scattered in some 1,300 references around the world. The book provides taxonomists, cell biologists, and ecologists with a thorough survey supplying synonyms, nomenclature and systematics, and an extensive description of morphology and ecology, including almost all published records, for each species.

Book Description
Conservation and biodiversity of protists The conservation of biodiversity is not just an issue of plants and vertebrates. It is the scarcely visible invertebrates and myriads of other microscopic organisms that are crucial to the maintenance of ecological processes on which all larger organisms and the composition of the atmosphere ultimately depend. Biodiversity and Conservation endeavours to take an holistic view of biodiversity, and when the opportunity arises to issue collections of papers dealing with too-often neglected groups of organisms. The protists, essentially eukaryotes that cannot be classi?ed in the kingdoms of animals, fungi, or plants, include some of the lea- known groups of organisms on earth. They are generally treated as a separate kingdom, commonly named Protista (or Protoctista) in textbooks, but in reality they are a mixture of organisms with disparate a?nities. Some authors have hypothesized that the numbers of protists are not especially large, and that many have extraordinarily wide distributions. However, the p- ture that unfolds from the latest studies discussed in this issue is di?erent. There are many species with wide ranges, and proportionately more cosmopolitan species than in macroorganism groups, as a result of their long evolutionary histories, but there are also de?nite patterns and geographical restrictions to be found. Further, some protists are linked to host organisms as mutualists or parasites and necessarily con?ned to the distributions of their hosts.

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
This multi-disciplinary book will cater to students and those who want to have a more critical look behind the scenes of Antarctic science. This book will take a systems approach to providing insights into Antarctic ecosystems and the geophysical environment. Further, the book will link these insights to a discussion of current issues, such as climate change, bio prospecting, environmental management and Antarctic politics. It will be written and edited by experienced Antarctic researchers and scientists from a wide range of disciplines. Academic references will be included for those who wish to delve deeper into the topics discussed in the book.

Book Description
The International Committee on Microbial Ecology (ICOME) sponsors both the Interna tional Symposium on Microbial Ecology, held in various parts of the world at three-year intervals, and the publication of Advances in Microbial Ecology. Advances was estab lished to provide a vehicle for in-depth, critical, and even provocative reviews in microbial ecology and is now recognized as a major source of information for both practicing and prospective microbial ecologists. The Editorial Board of Advances nor mally solicits contributions from established workers in particular areas of microbial ecology, but individuals are encouraged to submit outlines of unsolicited contributions to any member of the Editorial Board for consideration for pUblication in Advances. Chapters in Volume 11 of Advances in Microbial Ecology include those on micro bial transformations of chitin by G. W. Gooday, organic sulfur compounds by D. P. Kelly and N. A. Smith, and phosphorus, including its removal in waste water treatment plants, by D. F. Toerien, A. Gerber, L. H. Lotter, and T. E. Cloete. The importance of diffusion processes in microbial ecology is discussed by A. L. Koch, and 1. I. Prosser reviews the application of mathematical modeling to nitrification processes. Considera tions of particular ecosystems include the Antarctic by D. D. Wynn-Williams and Australian coastal microbial mats by G. W. Skyring and 1. Bauld. Other chapters include the regulation of N2 fixation by H. W.
