Download or read book A Check List and Synonym Key for the Phylum Porifera written by Tim Williams and published by . This book was released on 2008-01-01 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sponges are an ancient group of invertebrate animals whose basic body plan has remained unchanged for millions of years. There are no distinct organs or tissues, digestion is intracellular with excretion and respiration being by diffusion. The classification of sponges presents many problems because they share very few characteristics with other animals. Some zoologists consider them to be outside the line of evolution which led to other animals, the metazoans. Consequently, sponges may be labeled as parazoans. This essential reference provides a complete list of all the known species of sponges (up to the end of 2007), along with a key to their synonyms. At the front of the book there is an outline classification to guide you to the location of unfamiliar species, followed by a synopsis of the phylum. This is followed by the checklist and synonym key. At the end of the book is an outline classification of the animal kingdom, and a brief bibliography.
Download or read book Systema Porifera written by John N.A. Hooper and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1779 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book A Guide to the Deep water Sponges of the Aleutian Island Archipelago written by Robert P. Stone and published by . This book was released on 2011 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Furthermore, sponges are extremely fragile and easily damaged by contact with fishing gear. High rates of fishery bycatch clearly indicate a strong interaction between existing fisheries and sponge habitat. Bycatch in fisheries and fisheries-independent surveys can be a major source of information on the location of the sponge fauna, but current monitoring programs are greatly hampered by the inability of deck personnel to identify bycatch. This guide contains detailed pecies descriptions for 112 sponges collected in Alaska, principally in the central Aleutian Islands. It addresses bycatch identification challenges by providing fisheries observers and scientists with the information necessary to adequately identify sponge fauna.Using that identification data, areas of high abundance can be mapped and the locations of indicator species of vulnerable marine ecosystems can be determined.

Download or read book Marine Genetics written by Antonio M. Solé-Cava and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our current knowledge of marine organisms and the factors affecting their ecology, distribution and evolution has been revolutionised by the use, in the last 20 years, of molecular population genetics tools. This book is the result of a meeting of world-leading experts, in Rio de Janeiro, where the state of the art of this field was reviewed. Topics covered include the molecular analysis of bio-invasions, the recent developments in marine biotechnology, the factors affecting levels of genetic variation and population structure in marine organisms and their application to conservation biology, fisheries and aquaculture. This is the first book dedicated to the genetic study of marine organisms. It will be very useful to biology students, scientists and anyone working or simply interested in areas such as marine biology, zoology, ecology, and population and molecular genetics.

Download or read book Climate Change Ocean Acidification and Sponges written by José Luis Carballo and published by Springer. This book was released on 2017-10-27 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
