This book was released on 2013-06-29 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the summer of 1988, under NATO sponsorship, approximately 80 scientists lived and worked together in Plymouth for two weeks to evaluate the ecological role of protozoa in the sea. Through the convivial surroundings, close working conditions and special facilities that had been brought together for NATO ASI 604/87 a 'melting pot' of ideas was formed, which stimulated the multidisciplinary creativity which is expressed in this book and in a second series of papers which will be published in Marine Microbial Food Webs under the title - "Protozoa and their Role in Marine Microbial Food Webs". Discussions of the role of protozoa in the microbial food web, in the cycling of carbon and nitrogen and the extent to which this web acts as a link or sink to metazoa in the water column were major themes of the ASI. Structured sessions covering oral and poster presentations, field work, model 1 ing, laboratory practicals and demonstrations of techniques such as image analysis and flow cytometry, formed the core of the meeting. Participants took part enthusiastically in the practical sessions developing new concepts and obtaining new insights into their work. The practicals included a 'protozoo' and some beautiful films and videos. Field excursions were made to a range of sites including a unique marine sewage farm at Looe in Cornwall, (Jones this volume). Interactive workshops allowed scientists with no modelling experience to input their results to three simulation models and a flow analysis package.

This book was released on 2012-12-06 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: In its statutory authority (National Science Foundation Act of 1950, as amended), the NSF is directed to both initiate and support basic scientific research. In its Ecology Program, one mode of initiating research is to en courage the development of new ideas through advisory workshops. The NSF is specifically directed to strengthen our nation's research potential. In addition, stimulating new approaches to research will continue to be prominent in the coming years as federal attention is given to increasing the innovativeness and competitiveness of the U. S. in science and engineering. A decision to initiate a workshop does not arise de novo in the Ecology Program. Rather, it emerges from panel discussions, conversations with in vestigators at meetings or on the phone, and from discussions between pro gram officers in the Division of Biotic Systems and Resources. This workshop was developed to provide advice to the NSF and the lim nological community. Some NSF perceptions on future funding for ecolog ical research on lake communities are presented here. Researchers often mentioned a paucity of innovative lake ecology at the community level. This perception was accompanied by a certain frustration since lakes probably have the best empirical data base of any natural environment and should continue to lead in the development of ecological concepts. Members of NSF advisory panels sometimes expressed similar concerns during consid eration of proposals for lake research.
Download or read book Ecology of Protozoa written by Genoveva F. Esteban and published by Springer Nature. This book was released on 2021-01-04 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Soil Protists written by Stefan Geisen and published by Sudwestdeutscher Verlag Fur Hochschulschriften AG. This book was released on 2015-10-13 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protists are by far the most diverse and abundant eukaryotes in soils. Nevertheless, very little is known about individual representatives, the diversity and community composition and ecological functioning of these important organisms. For instance, soil protists are commonly lumped into a single functional unit, i.e. bacterivores. This work tackles missing knowledge gaps on soil protists and common misconceptions using multi-methodological approaches including cultivation, microcosm experiments and environmental sequencing. In a first part, several new species and genera of amoeboid protists are described showing their immense unknown diversity. In the second part, the enormous complexity of soil protists communities is highlighted using cultivation- and sequence-based approaches. In the third part, the present of diverse mycophagous and nematophagous protists are shown in functional studies on cultivated taxa and their environmental importance supported by sequence-based approaches. This work is just a start for a promising future of soil Protistology that is likely to find other important roles of these diverse organisms.

Download or read book Explore the World Using Protozoa written by National Science Teachers Association and published by NSTA Press. This book was released on 1997 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Protozoa may not be the first things that come to mind when you think of adaptation, evolution, food webs, succession, physiology, life strategies, and chemical susceptibility. These microorganisms, however, are a great tool to model these and other macro-concepts. Protozoa perform many of the same biological and ecological activities seen in their macroscopic counterparts. And they are much easier to find and cultivate. This book's 28 hands-on activities will help teach organizing principles of biology and ecology, and make links to other disciplines."--Back cover

Download or read book Soil Protozoa written by J. F. Darbyshire and published by Oxford University Press, USA. This book was released on 1994 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protozoa are active components of the soil microfauna. For example, they may stimulate bacterial metabolism and some fungal metabolites can lyse protozoa. They may be predators of bacteria and hence have a role in biological control. Their presence in groundwaters can be used as an indicator of pollution, while they are also being used to treat sewage in the activated-sludge and reed-bed processes. They are believed to be major secondary decomposers in soil and increased knowledge about these microorganisms is important to sustain soil fertility and food production. This book is the first in English for 65 years devoted entirely to soil protozoology. It is written by experienced microbiologists and should be of interest to protozoologists, other microbiologists, and soil scientists.

Download or read book Microbial Ecology of the Oceans written by David L. Kirchman and published by Wiley-Liss. This book was released on 2000-05 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wiley Series in Ecological and Applied Microbiology, Ralph Mitchell, Series Editor Microbial ecology is now recognized to be fundamental for understanding the natural world around us and is essential for examining life in the oceans. For the first time, this book brings together international experts to explore the incredibly diverse collection of microbes (and viruses) found in the oceans and to dissect many of the processes mediated by these microbes in aquatic environments. Although the oceans are emphasized, the organisms and processes discussed in the book occur in nearly all natural environments, including rivers and lakes. Microbial Ecology of the Oceans reviews some basics of marine microbiology andprovides a foundation for researchers and students new to the field while also examining several questions currently being discussed in modern microbial ecology. The book brings together concepts from autoecological studies of individual bacterial groups and from ecological studies of microbial assemblages in the oceans. In addition to drawing on the rich history of microbiology, Microbial Ecology of the Oceans uses the latest advances in biological and chemical oceanography and limnology to examine the role of marine microbes and viruses in the oceans. Some of the topics covered by this informative book include: * Microbial evolution, as revealed by molecular techniques * Microbes in carbon budgets and cycles * Viruses and grazers of bacteria * Competition between bacteria and phytoplankton for limited nutrientsMarine symbiosis Microbial Ecology of the Oceans elucidates the role of microbes in food web dynamics and biogeochemical cycles in the ocean. It will prove to be an indispensable resource for students and researchers in biological and chemical oceanography, geochemistry, marine chemistry, freshwater ecology, and microbiology.
