This book was released on 2020-10-13 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Associations of marine algae with symbiotic or parasitic microorganisms are ubiquitous phenomena known for a long time. However, there is an almost complete lack of knowledge on details of such interactions. The intention of this study is to use the potentials of modern biological and biochemical techniques in order to analyze the reaction of brown algal hosts to the attack by pathogens and epibionts. A 3-year field study at different localities on the European Atlantic coast revealed that Pylaiella littoralis populations were subject to massive epidemics of the parasites Eurychasma dicksonii, Chytridium polysiphoniae and Anisolpidium rosenvingei. Laboratory cultures were used to investigate the association of Eurychasma and Chytridium with brown algal hosts from different taxonomic groups: Eurychasma has a much broader host range than Chytridium, comprising members of all brown algal orders investigated, and it tolerates a wider range of temperatures than the latter. Phylogenetic studies based upon 18 S rRNA genes revealed that Eurychasma dicksonii belongs to the Oomycota, branching at an ancestral position between terrestrial plant pathogens and free-living members of the marine heterotrophic picoplankton. Chytridium polysiphoniae, a fungus, appears more closely related to the genera Rhizophydium and Spizellomyces (Chytridiomycota) than to other known Chytridium species. Chytridium produces chitin, whilst Eurychasma does not. Early stages of Eurychasma infection have a rather modest effect on host physiology. The photosynthetic capacity is enhanced, suggesting a temporary stimulation of host metabolism for hypertrophic growth. Chytridium, in contrast, has an immediate detrimental effect on host photosynthesis, which breaks down once a cell is infected, leading to the rapid death of infected cells.

Book Synopsis The Ecology and Evolution of Inducible Defenses by : Ralph Tollrian
Download or read book The Ecology and Evolution of Inducible Defenses written by Ralph Tollrian and published by Princeton University Press. This book was released on 1999-01-17 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inducible defenses--those often dramatic phenotypic shifts in prey activated by biological agents ranging from predators to pathogens--are widespread in the natural world. Yet research on the inducible defenses used by vertebrates, invertebrates, and plants in terrestrial, marine, and freshwater habitats has largely developed along independent lines. Tollrian and Harvell bring together leading researchers from all fields to review common themes and explore emerging ideas. Contributors examine organisms as different as unicellular algae and higher vertebrates, and consider defenses ranging from immune systems to protective changes in morphology, behavior, chemistry, and life history.

Book Synopsis Seagrasses of Australia by : Anthony W. D. Larkum
Download or read book Seagrasses of Australia written by Anthony W. D. Larkum and published by Springer. This book was released on 2018-07-27 with total page 791 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book takes the place of “Biology of Seagrasses: A Treatise on the Biology of Seagrasses with Special Reference to the Australian Region”, co-edited by A.W.D. Larkum, A.J. MaCComb and S.A. Shepherd and published by Elsevier in 1989. The first book has been influential, but it is now 25 years since it was published and seagrass studies have progressed and developed considerably since then. The design of the current book follows in the steps of the first book. There are chapters on taxonomy, floral biology, biogeography and regional studies. The regional studies emphasize the importance of Australia having over half of the world’s 62 species, including some ten species published for Australia since the previous book. There are a number of chapters on ecology and biogeography; fish biology and fisheries and dugong biology are prominent chapters. Physiological aspects again play an important part, including new knowledge on the role of hydrogen sulphide in sediments and on photosynthetic processes. Climate change, pollution and environmental degradation this time gain an even more important part of the book. Decline of seagrasses around Australia are also discussed in detail in several chapters. Since the first book was published two new areas have received special attention: blue carbon and genomic studies. Seagrasses are now known to be a very important player in the formation of blue carbon, i.e. carbon that has a long turnover time in soils and sediments. Alongside salt marshes and mangroves, seagrasses are now recognized as playing a very important role in the formation of blue carbon. And because Australia has such an abundance and variety of seagrasses, their role in blue carbon production and turnover is of great importance. The first whole genomes of seagrasses are now available and Australia has played an important role here. It appears that seagrasses have several different suites of genes as compared with other (land) plants and even in comparison with freshwater hydrophytes. This difference is leading to important molecular biological studies where the new knowledge will be important to the understanding and conservation of seagrass ecosystems in Australia. Thus by reason of its natural abundance of diverse seagrasses and a sophisticated seagrass research community in Australia it is possible to produce a book which will be attractive to marine biologists, coastal scientists and conservationists from many countries around the world.
Book Synopsis Indicators for Waterborne Pathogens by : National Research Council
Download or read book Indicators for Waterborne Pathogens written by National Research Council and published by National Academies Press. This book was released on 2004-06-19 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent and forecasted advances in microbiology, molecular biology, and analytical chemistry have made it timely to reassess the current paradigm of relying predominantly or exclusively on traditional bacterial indicators for all types of waterborne pathogens. Nonetheless, indicator approaches will still be required for the foreseeable future because it is not practical or feasible to monitor for the complete spectrum of microorganisms that may occur in water, and many known pathogens are difficult to detect directly and reliably in water samples. This comprehensive report recommends the development and use of a "tool box" approach by the U.S Environmental Protection Agency and others for assessing microbial water quality in which available indicator organisms (and/or pathogens in some cases) and detection method(s) are matched to the requirements of a particular application. The report further recommends the use of a phased, three-level monitoring framework to support the selection of indicators and indicator approaches.Â
