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.

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.

The content is focused on benthic communities showing how they play an in important role in the river ecosystems. Provides also information on taxonomy of river-inhabiting algal groups, including phylogeny, distribution, collection, preservation and description of the most representative genera of algae in river benthic algal communities. The book also approaches the ecology of river algae not to mention the ecological factors influencing abundance, distribution and diversity of river benthic algal communities and their use as bio-indicators, providing an up-to-date information on taxonomy, ecology, methodology and uses, and a great source of research to everyone interested in freshwater algae, limnology, water quality assessment and biodiversity in river ecosystems.

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.

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.
