This book was released on 2010-04-11 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Band 21 der „Süßwasserflora von Mitteleuropa“ beschreibt die aquatischen Pilze. Der vorliegende Teil 21/1 behandelt die Süßwasserflechten (symbiotische Assoziationen von Pilzen mit Grünalgen oder Cyanobakterien), die man in fast allen Fließgewässern mit sauberem Wasser und steinigem Bett findet. Die Süßwasserflechten-Flora hat ein großes Potential als Bioindikator für Sedimenteintrag, Stabilität des Gewässerbetts, Konstanz der Überflutung und des ph-Wertes. Mit weniger als 100 Arten sind die Süßwasserflechten eine relativ kleine und systematisch sehr heterogene Gruppe von spezialisierten Pilzen, die die aquatische Lebensweise konvergent erworben haben. Sie gehören mehreren nicht näher verwandten Ordnungen der Ascomycota an.

Download or read book Automatic Diatom Identification written by Hans Du Buf and published by World Scientific. This book was released on 2002 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to deal with automatic diatom identification. It provides the necessary background information concerning diatom research, useful for both diatomists and non-diatomists. It deals with the development of electronic databases, image preprocessing, automatic contour extraction, the application of existing contour and ornamentation features and the development of new ones, as well as the application of different classifiers (neural networks, decision trees, etc.). These are tested using two image sets: (i) a very difficult set of Sellaphora pupula with 6 demes and 120 images; (ii) a mixed genera set with 37 taxa and approximately 800 images. The results are excellent, and recognition rates well above 90% have been achieved on both sets. The results are compared with identification rates obtained by human experts. One chapter of the book deals with automatic image capture, i.e. microscope slide scanning at different resolutions using a motorized microscope stage, autofocusing, multifocus fusion, and particle screening to select only diatoms and to reject debris. This book is the final scientific report of the European ADIAC project (Automatic Diatom Identification and Classification), and it lists the web-sites with the created public databases and an identification demo.

Book excerpt: Volume 7 of the series "Süßwasserflora/Freshwater Flora of Central Europe" covers the freshwater red algae and brown algae of this region. These organisms can be found in running waters, in lakes and ponds, on wet soils and sometimes also in hot sulphuric springs. This book is intended to aid both the algologists and applied researchers to correctly identify European freshwater algae using updated nomenclature. Detailed descriptions of all taxa and high-quality drawings and photographs of the species facilitate their identification are provided.
Download or read book Biological Monitoring of Heavy Metal Pollution written by M. H. Martin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past two decades there has been an increasing public awareness of the hazards that exist from the contamination of the environment by toxic substances. 'Heavy metals' and the terrestrial environment are but one facet of the impact of toxic substances on the natural environment, and the use of biological materials for indicating the occurrence of, and continually monitoring the presence of, these materials is a specific topic which is of considerable interest to a diverse range of individuals, organisations and disciplines. It was our intention when we first en visaged this book that it should contain a description of a range of circumstances in which biological monitoring techniques have been employed in the terrestrial environment and that it should be seen as a practical text which dealt with the merits, shortcomings and suitability of biological monitoring materials. Monitoring is, however, a manifold process. It serves not only to provide information on past and present concentrations of toxic materials in various components of the environ ment, but also to provide information on the processes of environmental release, transport, accumulation and toxicity. Indeed, this may be one of the greatest virtues of biological monitoring over other forms of monitor ing. According to the skill of the staff employed in the monitoring procedure, the information that is accrued can have a vastly different value.

Download or read book The Diatom World written by Joseph Seckbach and published by Springer Science & Business Media. This book was released on 2011-07-23 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diatom biology, genomics and ecology are becoming more relevant to the human species. While there have been recent compilations of some of the applied aspects of diatoms, and the dizzying pace of taxonomic revisions, this new volume bring us up to date on their classification, biology and ecology, as well as covering the topics of genomics and applied uses. In this collection, some of the leaders in diatom research present either new information or summarize recent research efforts on a wide range of topics, including the tree of life of diatoms, their classifications, the wide habitats and ecological spectra the group exploits, as well as the beauty of their form. This volume celebrates the diversity, emerging areas of research and fascinating ecology of the diatoms bringing this group of world-renown and emerging research leaders together. 'The Diatom World' will foster greater appreciation and research contributions on this incredibly diverse and fascinating group of organisms.

Download or read book Modern Trends in Diatom Identification written by Gabriel Cristóbal and published by Springer Nature. This book was released on 2020-05-28 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-resolution images of phytoplankton cells such as diatoms or desmids, which are useful for monitoring water quality, can now be provided by digital microscopes, facilitating the automated analysis and identification of specimens. Conventional approaches are based on optical microscopy; however, manual image analysis is impractical due to the huge diversity of this group of microalgae and its great morphological plasticity. As such, there is a need for automated recognition techniques for diagnostic tools (e.g. environmental monitoring networks, early warning systems) to improve the management of water resources and decision-making processes. Describing the entire workflow of a bioindicator system, from capture, analysis and identification to the determination of quality indices, this book provides insights into the current state-of-the-art in automatic identification systems in microscopy.
