Aspects of Sponge Biology is the result of a symposium about sponge biology held in Albany, New York in May 1975. The symposium not only presents investigations, but also problem areas in the field of sponge biology. This book therefore shows that sponges are a very challenging and untouched subject area for future studies. This book is divided into three major parts, wherein the first part introduces and discusses sponge biology. The introduction and discussion include sponge biology principles, perspectives, and problems. The next two parts discuss cell and development biology, taxonomy, and ecology. Part 2 deals with several topics of the cellular aspect, including an analysis of reproduction in sponge populations and cytochemical studies of connective tissues in sponges. This part also looks into the cytological abnormalities in various normal and transformed cell lines. Part 3 describes the different types of sponge in their various habitats. Sponge feeding mechanisms, ecological factors controlling sponge distribution, and zoogeography of Brazilian marine Demospongiae are also discussed in this part. This book will be of important value to biology students and teachers. Specialists including zoologists, ecologists, comparative physiologists, and biologists will also benefit from this book.

Modem biology owes much to the study of favorable model systems which fa cilitates the realization of critical experiments and results in the introduction of new concepts. Examples of such systems are numerous and studies of them are regularly recognized by the scientific community. The 1983 Nobel Prize in Med icine and Physiology is a magnificent example in which com plants served as the experimental model. In a manner somewhat more modest, other biological systems have attracted recognition due to their critical phylogenetic position, or indeed because of their uniqueness which distinguishes them from all other organisms. Assuredly, among the whole assemblage ofliving organisms, sponges stand out as worthy of interest by scientists: they are simultaneously models, an important group in evolution, and animals unlike others. As early as the beginning of this century, sponges appeared as exceptional models for the study of phenomena of cell recognition. Innumerable works have been dedicated to understanding the mechanisms which assure the reaggregation of dissociated cells and the reconstitution of a functional individual. Today, re search on these phenomena is at the ultimate, molecular level. Through an as semblage of characteristics the sponges are, based upon all available evidence, the most primitive Metazoans. Their tissues-perhaps one can say their cell groups-are loosely assembled (they possess no tight or gap junctions), cell dif ferentiation appears highly labile, and they do not develop any true organs. But, they are most certainly Metazoans.

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.

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.

The main focus of this book entitled is to provide an up-to-date coverage of marine sponges and their significance in the current era. This book is an attempt to compile an outline of marine sponge research to date, with specific detail on these bioactive compounds, and their pharmacological and biomedical applications. The book encompasses twenty chapters covering various topics related to Marine Sponges. Initial couple of chapters deal about the worldwide status of marine sponge research, the recent findings regarding dynamics of sponges, and several interesting research areas, that are believed to be deserving of increased attention. Variety of sponges, their toxicology, metagenomics, pharmaceutical significance and their possible applications in biomedicine has been discussed in detail. The second half of this part includes chapters on chemical ecology of marine sponges followed by the discussion on importance of bioeroding sponges in aquaculture systems. The following four chapters of the book deal majorly with the chemical molecules of marine sponges. In the fifth chapter, marine sponge-associated actinobacteria and their pysicochemical properties have been discussed followed by their bioactive potential. The biological application of marine sponges has been presented in later chapters with the classification of biologically active compounds being explored in detail. The second half of the book presents the vast repertoire of secondary metabolites from marine sponges, which include terpenoids, heterocycles, acetylenic compounds, steroids and nucleosides. Further, the bioactive potential of these compounds has also been discussed. One of the constituent chapter elaborates the bioactive alkaloids from marine sponges namely, pyridoacridine, indole, isoquinolene, piperidene, quinolizidine, steroidal and bromotyrosine alkaloids isolated from them. In the next couple of chapters, important sponge polymers and the anticancer effects of marine sponge compounds have been presented. The most interesting aspect of sponge biology is their use in biomedical arena. An effort has been made in this book, to cover the major constituents of sponges and their biomedical potentials. The major portion of sponge body is composed of collagen and silica and used in tissue engineering as scaffold material. This part of the book compiles chapters delineating the isolation of sponge biomaterials including collagen and their use in medical diagnostics. Overall, this book would be an important read for novice and experts in the field of sponge biology.

Knowledge in the field of the biology of the extracellular matrix, and in particular of collagen, has made considerable progress over the last ten years, especially in mammals, birds and ln man with respect to very important applied medical aspects. Basic knowledge in the animal kingdom overall has increased more slowly and haphazardly. We, therefore, considered it useful to organize a meeting specifically devoted to the study of the invertebrate and lower vertebrate collagens. The NATO Scientific Division financed an Advanced Research Workshop aimed at bringing together experts qualified in collagen biology (with morphological, biochemical and genetic specialization) with researchers who are currently studying collagenous tissues of invertebrates and lower vertebrates. The Medical-Biology Committee of the CNR-Rome and the University of Milan also supplied interest and support for the organization of this Meeting. The format of the workshop consisted in: 1) main lectures on the most recent aspects of collagen biology; 2) minireviews on the current knowledge of collagenous tissues in the various invertebrate phyla and in fish; 3) contributed papers on particular aspects of research in specific fields; 4) workshops on the methodology of studying collagen. As we had intended, the Workshop gave a comprehensive overview of acquired knowledge and of the present state of research actlvlty. It permitted wide interdisciplinary discussion, enabling collabora tions to be established and new research themes to be chosen. This volume contains the text of all the contributions presented at the Meeting, including posters.

Climate Change, Ocean Acidification and Sponges

While sponges represent a very simple group of organisms, which are represented by over 8000 species, there is considerable interest in the increasing role they may play in future marine ecosystems. While we still have a comparatively limited understanding of how sponges will respond to ocean warming and acidification there is evidence that some species may have the ability to acclimate or even adapt to these stressors. This comprehensive collection of articles describes our current understanding of the impacts of ocean acidification and warming on sponges across multiple levels of biological organisation, and from the geological past to the present. With expert contributions from across the world this book represents the most up-to-date view on sponge responses to climate change. This book will be of interest to a wide audience of marine scientists and managers, who are grappling with how to manage, conserve and protect marine ecosystems.

The Biology of Reefs and Reef Organisms

Reefs provide a wealth of opportunity for learning about biological and ecosystem processes, and reef biology courses are among the most popular in marine biology and zoology departments the world over. Walter M. Goldberg has taught one such course for years, and he marshals that experience in the pages of The Biology of Reefs and Reef Organisms. Goldberg examines the nature not only of coral reefs—the best known among types of reefs—but also of sponge reefs, worm reefs, and oyster reefs, explaining the factors that influence their growth, distribution, and structure. A central focus of the book is reef construction, and Goldberg details the plants and animals that form the scaffold of the reef system and allow for the attachment and growth of other organisms, including those that function as bafflers, binders, and cementing agents. He also tours readers through reef ecology, paleontology, and biogeography, all of which serve as background for the problems reefs face today and the challenge of their conservation. Visually impressive, profusely illustrated, and easy to read, The Biology of Reefs and Reef Organisms offers a fascinating introduction to reef science and will appeal to students and instructors of marine biology, comparative zoology, and oceanography.
