Download or read book The Biology of Ascidians written by H. Sawada and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ascidians are the invertebrate group that gave rise to vertebrates, thus the biology of ascidians provides an essential key to understanding both invertebrates and vertebrates. This book is the first to cover all areas of ascidian biology, including development, evolution, biologically active substances, heavy metal accumulation, asexual reproduction, host-defense mechanisms, allorecognition mechanisms, comparative immunology, neuroscience, taxonomy, ecology, genome science, and food science. The 69 articles that make up the collection were contributed by leading ascidiologists from all over the world who participated in the First International Symposium on the Biology of Ascidians, held in June 2000 in Sapporo, Japan. For scientists and students alike, the book is an invaluable source of information from the latest, most comprehensive studies of ascidian biology.

Download or read book Sea Squirts and Sea Sponges of Britain and Ireland written by Sarah Bowen and published by Princeton University Press. This book was released on 2018-07-09 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea squirts and sponges are found in most seafloor habitats around the coasts of Britain and Ireland. Despite being the dominant life forms in many areas, these two groups of under-recorded marine animals are often confused with one another, and most divers and snorkellers can recognise and name very few species. In fact, around 500 species of Ascidiacea (sea squirts) and Porifera (sponges) have been described so far in British and Irish seas, corresponding to over 4% of the world’s total. This book is recommended reading for anyone who wants to identify and discover more about these fascinating and diverse animals. Rather than relying on the characteristics of preserved specimens, this guide uses marine photography and detailed underwater observations to concentrate on in situ features, allowing you to record species without collecting them. Most sea squirts found in Britain and Ireland’s shallow waters are included, together with the most easily recognised sponges. Whether you are a student, a diver, a rockpooler or simply an enthusiast, this is an essential companion. ● Over 115 species described in detail with in situ photographs to help with underwater recognition ● Information on size, depth, habitat and distribution ● Key distinguishing features and areas of confusion in identification highlighted ● Details of body structure, life histories, digestive and reproductive processes ● Information about predators, interactions between species, non-native and problem invasive species

Download or read book Treatise on Zoology - Anatomy, Taxonomy, Biology. The Gregarines (2 vols) written by Isabelle Desportes and published by BRILL. This book was released on 2013-05-23 with total page 793 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phylum Apicomplexa is characterized by the unique cell organisation of the zoites, the infective stages of unicellular parasites previously designated as Sporozoa. Apicomplexa includes Coccidian and Hematozoa well known for human and veterinary diseases they cause, such as malaria, toxoplasmosis, babesiosis, coccidiosis, and the large group of Gregarines, the early branching Apicomplexa. Gregarines are parasite of invertebrates and urochordates and they performed an extraordinary radiation from the marine and terrestrial hosts known from the Cambrian biodiversity explosion. After the basic publication in the Traité de Zoologie by Grassé in 1953, this second edition updates the knowledge with information provided by new technologies such as electron microscopy, biochemistry and molecular biology and to enlighten their high diversity of adaptation to invertebrate hosts living in a diversity of biotopes. The extracellular development of Gregarines, the considerable diversification of their cell cortex, their wide distribution in Annelids, Crustaceans, Echinoderms, Myriapods or Insects with about hundred thousands of species contribute to the understanding of many biological aspects of the pathogenic Apicomplexa. Since 1953, taxonomical reviews on Gregarines were published in the Illustrated Guide of Protozoa. In this supplement, there is a special emphasis on the hosts. Contributors include: Stuart Goldstein, Ryoko Kuriyama, Gérard Prensier, Jiri Vavra, Lawrence Howard Bannister, Jean François Dubremetz. Without the financial support of academic and non-profit organisations the edition of this volume would not have been possible.

Download or read book Reproduction and Development in Minor Phyla written by T. J. Pandian and published by CRC Press. This book was released on 2021-05-14 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 26 recognized minor phyla comprise aberrant clades, as most of them terminate as blind offshoots. Untied from the discussion on their phylogenesis of minor phyla, this book is largely devoted, for the first time, to aspects of reproduction and development in minor phyletics. The minor phyla are not as speciose (1,795 species/phylum) as the major phyla (157,066 species/phylum) are. The accumulation of deleterious genes causes inbreeding depression among progenies arising from parthenogenesis, clonal multiplication and selfing hermaphrodites. The reason for the limited species diversity in minor phyla is traced to (i) eutelism in 65.7% of minor phyletics and (ii) existence of 21.6% clonals, (iii) 6.4% parthenogens and (iv) 1.2% selfing hermaphroditism. Gonochorism obligately requires motility to search for a mate. The combination of low motility and gonochorism from Placozoa to hemocoelomatic minor phyla has limited diversity to

Available in PDF, EPUB and Kindle. Book excerpt: The Ecology of the Indonesian Seas distills for the first time the information found in thousands of scholarly works relevant to an understanding of the sustainable use of marine and coastal resources in these islands&8212;many of them available up to now only in Dutch, German or Indonesian. It is an invaluable tool for government planners, resource managers, ecologists, university students, scuba divers, and all those with an interest in the sea. The second volume discusses the origins, formation and distribution of various reef types in the Indonesian Archipelago, and provides new estimates on their extent. The second volume also provides a review of the ecology of Indonesian seagrass, mangrove and open-ocean ecosystems. The chapter on marine biodiversity focuses on a number of marine and coastal habitats and threatened marine organisms. The final two chapters discuss what recent effects the human race has had on marine resources, and what we can do to protect and preserve our marine and coastal zones for generations to come.

Download or read book Vanadium in Biological Systems written by N.D. Chasteen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past several decades, vanadium has increasingly attracted the interest of biologists and chemists. The discovery by Henze in 1911 that certain marine ascidians accumulate the metal in their blood cells in unusually large quantities has done much to stimulate research on the role of vanadium in biology. In the intervening years, a large number of studies have been carried out to investigate the toxicity of vanadium in higher animals and to determine whether it is an essential trace element. That vanadium is a required element for a few selected organisms is now well established. Whether vanadium is essential for humans remains unclear although evidence increasingly suggests that it probably is. The discovery by Cantley in 1977 that vanadate is a potent inhibitor of ATPases lead to numerous studies of the inhibitory and stimulatory effects of vanadium on phosphate metabolizing enzymes. As a consequence vanadates are now routinely used as probes to investigate the mechanisms of such enzymes. Our understanding of vanadium in these systems has been further enhanced by the work of Tracy and Gresser which has shown striking parallels between the chemistry of vanadates and phosphates and their biological compounds. The observation by Shechter and Karlish, and Dubyak and Kleinzeller in 1980 that vanadate is an insulin mimetic agent has opened a new area of research dealing with the hormonal effects of vanadium. The first vanadium containing enzyme, a bromoperoxidase from the marine alga Ascophyllum nodosum, was isolated in 1984 by Viltner.
