Freshwater Algae provides a comprehensive guide to temperate freshwater algae, with additional information on key species in relation to environmental characteristics and implications for aquatic management. Existing books on freshwater algae fall into two categories: simple identification texts or highly specialised research volumes. There is currently nothing in between that practitioners and students can use on a regular basis. The authors filled this gap with the first edition which provided an accessible, visually appealing volume that is of immediate use to aquatic biologists for algal identification that includes key environmental information on major species. The book is divided into two parts: part I is a general introduction to algae and techniques for sampling, measuring and observation and then looks at the role of algae as bioindicators and the implications for aquatic management, part II provides the identification of major genera and 250 important species. The book is well illustrated in full colour with numerous original illustrations and photographs. This new revised edition will retain the same clear writing style and accessible format of the first edition with new coverage of species from North America, Asia and Australia in addition to expanded coverage of molecular and computational techniques in algal biology.

This practical manual of freshwater ecology and conservation provides a state-of-the-art review of the approaches and techniques used to measure, monitor, and conserve freshwater ecosystems. It offers a single, comprehensive, and accessible synthesis of the vast amount of literature for freshwater ecology and conservation that is currently dispersed in manuals, toolkits, journals, handbooks, 'grey' literature, and websites. Successful conservation outcomes are ultimately built on a sound ecological framework in which every species must be assessed and understood at the individual, community, catchment and landscape level of interaction. For example, freshwater ecologists need to understand hydrochemical storages and fluxes, the physical systems influencing freshwaters at the catchment and landscape scale, and the spatial and temporal processes that maintain species assemblages and their dynamics. A thorough understanding of all these varied processes, and the techniques for studying them, is essential for the effective conservation and management of freshwater ecosystems.

Algen spielen neben den Bakterien und Pilzen eine wichtige Rolle im Bodenleben. Zur Vertiefung der Kenntnis bodenbewohnender eukaryontischer Algen fehlte bisher ein Bestimmungswerk, das die weltweit verstreuten Daten zusammengefasst darstellt. Über 1000 Algenarten sind bislang aus Böden, aus der Luft und aus Flechten beschrieben, doch ist das Wissen über Lebensvorgänge, Reproduktion, Entwicklung usw. noch sehr lückenhaft. Auch sind viele Bodenalgen überhaupt nur mittels Kulturen erfassbar. Dieser Syllabus enthält deshalb für 260 Gattungen und mehr als 1000 Arten aero-terrestrischer Algen entsprechende Bestimmungsschlüssel, Beschreibungen von Morphologie und Zytologie samt Abbildungen, dazu noch ergänzende Hinweise auf Vorkommen, Verbreitung und vorhandene Kulturen. Ein Sonderkapital ist dabei den eukaryontischen Flechtenalgen gewidmet. Die systematische Gliederung und Anordnung stellt einen Kompromiss zwischen den Auffassungen der klassischen und modernen Systematik unter besonderer Berücksichtigung der Lichtmikroskopie dar. Soweit möglich wurden neben der Originalliteratur auch Eigenbeobachtungen und Kulturen in die Bearbeitung mit einbezogen. An taxonomischen Namensänderungen und Neubeschreibungen ist die neue Familie Myrmeciaceae (Ordnung Chlorellales) hervorzuheben. Hinweise auf wichtige Literatur sollen zu weiterführenden Untersuchungen anregen. Im allgemeinen Teil finden sich wesentliche Informationen über Ökologie, Bestimmung und Kulturmethoden bei Bodenalgen sowie übersichtliche Darstellungen der charakteristischen morphologischen und zytologischen Merkmale der behandelten Algengruppen. Seit dem Erscheinen der 1. Auflage sind zahlreiche weitere aeroterrestrische Algen beschrieben und taxonomische Änderungen vorgenommen worden. Hinweise dazu und die entsprechenden Literaturangaben samt Register sind als Ergänzungsteil nach den Bildtafeln und vor der Literatur des Hauptteils eingefügt.

Trieste Publishing has a massive catalogue of classic book titles. Our aim is to provide readers with the highest quality reproductions of fiction and non-fiction literature that has stood the test of time. The many thousands of books in our collection have been sourced from libraries and private collections around the world.The titles that Trieste Publishing has chosen to be part of the collection have been scanned to simulate the original. Our readers see the books the same way that their first readers did decades or a hundred or more years ago. Books from that period are often spoiled by imperfections that did not exist in the original. Imperfections could be in the form of blurred text, photographs, or missing pages. It is highly unlikely that this would occur with one of our books. Our extensive quality control ensures that the readers of Trieste Publishing's books will be delighted with their purchase. Our staff has thoroughly reviewed every page of all the books in the collection, repairing, or if necessary, rejecting titles that are not of the highest quality. This process ensures that the reader of one of Trieste Publishing's titles receives a volume that faithfully reproduces the original, and to the maximum degree possible, gives them the experience of owning the original work.We pride ourselves on not only creating a pathway to an extensive reservoir of books of the finest quality, but also providing value to every one of our readers. Generally, Trieste books are purchased singly - on demand, however they may also be purchased in bulk. Readers interested in bulk purchases are invited to contact us directly to enquire about our tailored bulk rates.

Cyanoprokaryotes are probably the oldest organisms with plant metabolism. However, their cell structure and type of asexual reproduction prove their eubacterial origin. In spite of their existence from Precambrian onwards they have not lost their vitality, and still are able to colonize all possible biotopes, including very extreme environments (thermal springs up to 80 °C, rocks in extremely hot or cold deserts in both the tropics and Antarctica, hypersaline lakes and marshes, biotopes in volcanic regions, and other harsh habitats). This book is a review of all the cyanoprokaryotic taxonomic units, registered and recognizable from European natural biotopes, including the marine coasts. Our determination keys and taxonomic descriptions should permit the identification of natural populations, and should be related to known culture material. Numerous strains were isolated, kept in strain collections and used as important model organisms for experiments of various kinds. In culture only a few cyanoprokaryotes show the typical growth form known from nature, most others can be made to display their typical forms and life cycles by special procedures only. The identification of strains without previous knowledge of natural material needs to be carried out with special care. The aim of this book is to make possible the identification and standardization of known, morphologically and ecologically distinguishable cyanoprokaryotes that have been described from natural populations in Europe. Therefore, in the introductory part only data important for identification are presented. At the end of this chapter we append a list of basic literature, where all the detailed information necessary can be found. We have selected accurate drawings of the species described in the text. We also present illustrations of some non-European species if necessary for understanding the generic diacritical features or infrageneric diversity.
