Book Description
One of two special issues of Advances in Marine Biology focusing on sponge science, it features comprehensive reviews of the latest studies that are advancing our understanding of the fascinating marine phylum Porifera. The selected contributors are internationally renowned researchers in their respective fields and provide a thorough overview of the state-of-the-art of sponge science. This volume will become a reference to marine biologists with interest in benthic ecology and biotic interactions, including symbiosis; chemical and molecular ecology; systematics, phylogeny, and evolution; sponge culture and tissue engineering

Book Description
Cyanobacterial symbioses are no longer regarded as mere oddities but as important components of the biosphere, occurring both in terrestrial and aquatic habitats worldwide. It is becoming apparent that they can enter into symbiosis with a wider variety of organisms than hitherto known, and there are many more still to be discovered, particularly in marine environments. The chapters cover cyanobacterial symbioses with plants (algae, bryophytes, Azolla, cycads, Gunnera), cyanobacterial symbioses in marine environments, lichens, Nostoc-Geosiphon (a fungus closely related to arbuscular mycorrhiza fungi) symbiosis, and artificial associations of cyanobacteria with economically important plants. In addition, cyanobiont diversity, sensing-signalling, and evolutionary aspects of the symbiosis are dealt with. Renowned experts actively involved in research on cyanobacterial symbioses deal with ecological, physiological, biochemical, molecular, and applied aspects of all known cyanobacterial symbioses. This volume on cyanobacteria in symbiosis complements the two earlier volumes on cyanobacteria published by Kluwer (Molecular Biology of Cyanobacteria, edited by D.A. Bryant and Ecology of Cyanobacteria, edited by B.A. Whitton and M. Potts). Together, the three volumes provide the most comprehensive treatment of cyanobacterial literature as a whole. The book will serve as a valuable reference work and text for teaching and research in the field of plant-microbe interactions and nitrogen fixation.

Book Description
Research whilst compiling this book has uncovered a fauna about twice the size as that previously published in the literature and consequently Systema Porifera revises and stabilizes the systematics of the phylum to accommodate this new knowledge in a contemporary framework. Practical tools (key illustrations, descriptions of character) are provided to facilitate the assignment of approximately 680 extant and 100 fossil genera. Systema Porifera is unique making sponge taxonomy widely available at the practical level of classification (genera, families, order). It is a taxonomic revision of sponges and spongiomorphis (such as sphinctozoans and archaeocyathans) based on re-evaluation of type materials and evidence. It is also a practical guide to sponge identification providing descriptions and illustrations of characters and interpretation of their importance to systematics. Systema Porifera addresses many long standing nomenclatural problems and provides a sound baseline for future debate on sponges and their place in time and space. Systema Porifera describes 3 classes, 7 subclasses, 24 orders, 127 families and 682 valid genera of extant sponges (with over 1600 nominal generic names and an additional 500 invalid names treated). Treatment of the fossil fauna is less comprehensive or critical, although 6 classes, 30 orders, 245 families and 998 fossil genera are mentioned. Keys to all recent and many fossil taxa are provided.

Book Description
Sponges (phylum Porifera) are known to be very rich sources for bioactive compounds, mainly secondary metabolites. Main efforts are devoted to cell- and mariculture of sponges to assure a sustainable exploitation of bioactive compounds from biological starting material. These activities are flanked by improved technologies to cultivate bacteria and fungi which are associated with the sponges. It is the hope that by elucidating the strategies of interaction between microorganisms and their host (sponge), by modern cell and molecular biological methods, a more comprehensive cultivation of the symbiotic organisms will be possible. The next step in the transfer of knowledge to biotechnological applications is the isolation, characterization and structural determination of the bioactive compounds by sophisticated chemical approaches.

Book Description
The interdisciplinary field of marine chemical ecology is an expanding and dynamic science. It is no surprise that the breadth of marine organisms studied expanded in concert with developments in underwater technology. With its up-to-date subject reviews by experts, Marine Chemical Ecology is the most current, comprehensive book on the subject. The

Book Description
"Handbook of Marine Natural Products" takes a fresh approach to describing the major themes of research in this rapidly developing field. This two volume reference work begins with a section that provides a taxonomic survey of the secondary metabolites of diverse marine life including microbes, algae, and invertebrates. This is followed by a demonstration of the techniques and strategies employed in modern structure elucidation of complex natural products. The natural roles of marine natural products are then explored in a series of focused chapters which include the topics of symbiosis, anti-predation and antifouling, chemical interactions, and defence against UV stress. Various routes which facilitate the understanding of marine natural product biosynthesis are subsequently explained and these are followed by an extensive set of chapters on the biomedical potential of marine natural products. The latter portion of this section considers the technologies and scientific disciplines necessary for advancing bioactive marine natural product lead compounds into actual pharmaceuticals. The reference work finishes with a selection of chapters describing marine toxins and their impact on public health and seafood resources. Final thoughts presented at the end of the second volume focus on the future of this field of investigation and discovery research. This publication is presented as a reference handbook and general concepts are emphasized and illustrated with numerous interesting examples, graphical information, and a comprehensive index. "Handbook of Marine Natural Products" introduces students who are at advanced undergraduate and entry graduate student levels to this fascinating multidisciplinary field. It is an ideal desk companion for courses focusing on this contemporary area.
