Available in PDF, EPUB and Kindle. Book excerpt: Fossil and Recent Sponges contains articles on taxonomic, phylogenetic and ecological aspects of sponges of both biological and paleontological interest. They focus on three main topics: phylogeny and systematics, biology, and paleoecology of sponges. The reader is offered an overview over the most important aspects of current sponge research: - establishment of a new taxonomy based on mono phyletic groups (phylogenetic systematics) including recent and fossil taxa - new concepts of the biomineralisation of sponge skeletons - palaeoenvironmental analysis of fossil sponge buildups.
Download or read book The Comparative Embryology of Sponges written by Alexander V. Ereskovsky and published by Springer Science & Business Media. This book was released on 2010-03-27 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the major questions in the evolution of animals is the transition from unicellular to multicellular organization, which resulted in the emergence of Metazoa through a hypothetical Urmetazoa. The Comparative Embryology of Sponges contains abundant original and literary data on comparative embryology and morphology of the Porifera (Sponges), a group of 'lower Metazoa'. On the basis of this material, original typization of the development of Sponges is given and the problems concerning origin and evolution of Porifera and their ontogenesis are discussed. A morphogenetic interpretation of the body plan development during embryogenesis, metamorphosis and asexual reproduction in Sponges is proposed. Special attention is given to the analysis of characteristic features of the ontogenesis in Porifera. The book pursues three primary goals: 1) generalization of all existing information on individual development of sponges, its classification and a statement according to taxonomical structure of Porifera; 2) revealing of heterogeneity of morphogenesis and peculiarities of ontogeneses in various clades of Porifera, and also their correlations with the organization, both adult sponges, and their larvae; 3) revealing homology of morphogeneses in both Porifera and Eumetazoa, testifying to the general evolutionary roots of multicellular animals, and peculiar features of sponges' morphogeneses and ontogenesis. This book will be of interest to embryologists, zoologists, morphologists and researchers in evolutionary biology.
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.

Book excerpt: This book discusses the current direction of the research approach to extreme biomimetics through biological materials-inspired chemistry and its applications in modern technology and medicine. It is a resource covering topics of extreme (psychrophilic and thermopilic) biomineralization, solvothermal and hydrothermal chemistry of metal oxides and nanostructured composites, and bioinspired materials science in a diverse areas. The authors review the current advances in the extreme biomimetics research field and describe various approaches introduced and explored by their respective laboratories. • Details the basic principles of extreme biomimetics approach for design of new materials and applications; • Includes numerous examples of the hierarchical organization of hydrothermally or psychrophilically obtained biocomposites, structural bioscaffolds, biosculpturing, biomimetism, and bioinspiration as tools for the design of innovative materials; • Describes and details the principles of extreme biomimetics with respect to metallization of chemically and thermally stable biopolymers.
Download or read book Species Diversity of Animals in Japan written by Masaharu Motokawa and published by Springer. This book was released on 2016-11-26 with total page 718 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the status quo of the knowledge about the biodiversity in terrestrial, freshwater, and marine animals that live in Japan. Consisting of some 6,800 islands that are arrayed for approximately 3,500 km from north to south, the Japanese archipelago has a complex history in a paleogeographic formation process over time and harbors rich flora and fauna. This work will contribute to establishing a general biogeographic theory in archipelagoes around continental shelves. Facing the ongoing extinction crisis, one of the most important tasks for our generation is to bequeath this precious natural heritage to future generations. As the first step toward this goal, a species list has been compiled through solid, steady alpha-taxonomic work in each taxon. Furthermore, the phylogeography and population genetic structure for each species is elucidated for deeper understanding of the local fauna, the scientific results of which should be the basis for establishing conservation policies and strategies. Also the problem of alien or introduced species is investigated as another threat to the native fauna.Each of the 27 chapters is written by the most active specialist leading the field, thus readers can acquire up-to-date knowledge of the animal species diversity and their formation process of Japanese animals in the most comprehensive form available. This book is recommended for researchers and students who are interested in species diversity, biogeography, and phylogeography.

This book was released on 2012-12-06 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, new genes and their proteins that revealed striking new insights into the early evolution of multicellular animals have been identified and characterized from members of the lowest metazoan phylum, the porifera (sponges). The unexpected result was that the sequences obtained from sponge displayed high similarity to those found in higher metazoa; in consequence, it was concluded that during the transition from protozoa to metazoa the major structural and regulatory proteins evolved only once. The data gathered are now powerful arguments to establish monophyly of metazoa; in addition, new insights on the evolutionary diversification of metazoa were obtained.
Download or read book Marine Biological Materials of Invertebrate Origin written by Hermann Ehrlich and published by Springer Nature. This book was released on 2019-10-17 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work is a source of modern knowledge on biomineralization, biomimetics and bioinspired materials science with respect to marine invertebrates. The author gives the most coherent analysis of the nature, origin and evolution of biocomposites and biopolymers isolated from and observed in the broad diversity of marine invertebrate organisms and within their unusual structural formations. The basic format is that of a major review article, with liberal use of references to original literature. There is a wealth of new and newly synthesized information, including dozens of previously unpublished images of unique marine creatures and structures from nano- to microscale including high-resolution scanning and transmission electron micrographs. The material is organized effectively along both biological (phyla) and functional lines. The classification of biological materials of marine origin is proposed and discussed. Much of the pertinent data is organized into tables, and extensive use is made of electron micrographs and line drawings. Several modern topics e.g. “biomineralization- demineralization-remineralization phenomena”, or “phenomenon of multiphase biomineralization”, are discussed in details. Traditionally, such current concepts as hierarchical organization of biocomposites and skeletal structures, structural bioscaffolds, biosculpturing, biomimetism and bioinspiration as tools for the design of innovative materials are critically analyzed from both biological and materials science point of view using numerous unique examples of marine origin. This monograph reviews the most relevant advances in the marine biomaterials research field, pointing out several approaches being introduced and explored by distinct laboratories.
Download or read book In Deeper Waters written by Edith H. Chave and published by University of Hawaii Press. This book was released on 1998-03-01 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thousands of meters beneath the surface of Hawaii's warm, sunlit waters lies the vast Hawaiian Ridge, a dark, cold region more than 2,600 kilometers in length. Its undersea mountains, sediment plains, lava flows, and volcanic vent fields are home to a variety of unusual deep-sea organisms. Since 1965, the ridge's unique geological features and animal communities have been studied with the aid of submersibles. This copiously illustrated volume describes 200 animals and geological formations photographed and collected by the University of Hawaii's HURL (Hawaii Undersea Research Laboratory) submersibles around the Hawaiian Islands, Cross Seamount, Loihi Volcano, and Johnston Atoll. In Deeper Waters is a valuable record for the professional and amateur marine biologist and geologist alike and adds substantially to our knowledge of deep-sea floor features and the distribution and behavior of their inhabitants.
