Download or read book Lake Pavin written by Télesphore Sime-Ngando and published by Springer. This book was released on 2016-10-31 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.

Download or read book Marine and Coastal Systems of the Quoddy Region New Brunswick written by Martin Lewis Hall Thomas and published by . This book was released on 1983 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book describes the main marine and coastal biological systems of Passamaquoddy Bay and adjacent waters and the oceanographic and meteorological characteristics of the area. Subject areas begin with meteorolgy and oceanography. The second group covers the intertidal systems with chapters on rocky intertidal shores, rock pools, coarse sedimentary shores and salt marshes. The third general section covers hard and sedimentary sublittoral habitats. Following chapters discuss pelagic systems under the headings fishes, phytoplankton, larger zooplankton, and microzooplankton. Three chapters deal with the birds, amphibians and reptiles, and marine mammals. Finally coastal vegetation is described.

Download or read book Algal Toxins Nature Occurrence Effect and Detection written by Valtere Evangelista and published by Springer Science & Business Media. This book was released on 2008-06-27 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the lectures and seminars given at the NATO Advanced Study Institute on “Sensor Systems for Biological Threads: The Algal Toxins Case”, held in Pisa, Italy in October, 2007. The Institute was sponsored and funded by the Scientific Affairs Division of NATO. It is my pleasant duty to thank this institution. This ASI offered updated information on how far the research on algal toxins has gone in the exploration of structures, biosynthesis and regulation of toxins, and the development of technology for bio-monitoring these c- pounds. Algae can form heavy growths in ponds, lakes, reservoirs and sl- moving rivers throughout the world; algae can house toxins which are - ually released into water when the cells rupture or die. Hundreds of toxins have been identified so far. Detection methods, including rapid screening, have been developed to help us learning more about them, especially to find out which toxins are a real threat for people and what conditions encourage their production and accumulation. Early detection of algal toxins is an - portant aspect for public safety and natural environment, and significant efforts are underway to develop effective and reliable tools that can be used for this purpose.

Download or read book Travertine written by Allan Pentecost and published by Springer Science & Business Media. This book was released on 2005-07-22 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: uring the spring of 1960, an uncle showed me a ‘petrifying spring’ near Plaxtol in Kent Dwhere twigs had been encased in a calcareous jacket. A twig was collected and having - cently been given I. Evan’s Observer’s Book of Geology by my parents, I found a photograph of another petrifying spring and an explanation of its origin. In those days, Derbyshire was too far for a holiday destination, and I took little further interest until a research studentship with Professor G. E. Fogg became available in 1971. Tony Fogg had recently moved to the University College of North Wales, Bangor and the research was to be into cyanobacterium mats, with fieldwork along the Red Sea coast. The fieldwork never materialised but my interest in algal mats had been aroused. A chance stroll along the Bangor shore revealed beautifully calcified cya- bacterium mats, and Tony generously allowed me to investigate these instead. The old Plaxtol collection was retrieved and yielded abundant cyanobacteria. It became apparent that here was a wealth of information about a rock whose formation was so rapid, that the process could be studied in days rather than years – an exceptional state of affairs. A search of the literature also revealed that the rock, a form of travertine, had other unusual features.

Download or read book Symbolic Construction of Community written by Anthony P. Cohen and published by Routledge. This book was released on 2013-03-07 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthony Cohen makes a distinct break with earlier approaches to the study of community, which treated the subject in largely structural terms. His view is interpretive and experiential, seeing the community as a cultural field with a complex of symbols whose meanings vary among its members. He delineates a concept applicable to local and ethnic communities through which people see themselves as belonging to society. The emphasis on boundary is sensitive to the circumstances in which people become aware of the implications of belonging to a community, and describes how they symbolise and utilise these boundaries to give substance to their values and identities.
