Download or read book Lessons in Immunity written by Loriano Ballarin and published by Academic Press. This book was released on 2016-04-08 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lessons in Immunity: From Single-cell Organisms to Mammals stems from the activity of the Italian Association of Developmental and Comparative Immunobiology (IADCI), represented by the editors. This book is presented as a series of short overviews that report on the current state of various relevant fields of immunobiology from an evolutionary perspective. The overviews are written by authors directly involved in the research, and most are members of the IADCI or have otherwise been involved in the related research for their respective overview. This publication offers scientists and teachers an easy and updated reference tool. - Provides simple and updated reviews on the immunobiology of a wide spectrum of organisms, considered in an evolutionary context - Focuses on both cells and humoral components of a variety of non-classical model organisms - Offers in a single volume many contributions which can help with understanding the evolution of immune responses and the main adaptations in animal phyla - Presents a valuable holistic cross-sectional approach for teaching immunology and its applications

Download or read book Recent Antarctic and Subantarctic Brachiopods written by Merrill W. Foster and published by American Geophysical Union. This book was released on 1974 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 21. The Recent brachiopod faunas from southernmost South America, Antarctica, and the Subantarctic consisting of 21 genera and 37 species are described from new material. New taxa include the genera Manithyris and Bathynanus. Also new are 11 species: Compsothyris ballenyi, Hispanirhynchia? chiliensis, Manithyris rossi, Liothyrella multiporosa, Liothyrella scotti, Bathynanus tenuicostatus, Eucalathis macrorhynchus, Amphithyris hallettensis, Dallina eltanini, Fallax antarcticus, and Magellania? spinosa. Factor analysis was used to study relationships among morphological characters and environmental parameters. In Liothyrella, negative associations were found between beak height and water depth. The size of the pedicle opening within this genus is associated with the width of the hinge plate and the loop; apparently, these associations are related to increased dorsal adjustor muscle size with increased pedicle size. Similar relationships are found in the terebratellids, although here all of the characters are also negatively associated with water depth. Characters negatively associated with water depth may relate to the differing current strength at various depths. Puncta density is positively correlated with water temperature. Examples of brachiopod variation are discussed. Synonyms have resulted from former failure to study large samples and to appreciate the extent of brachiopod variation. A priori valuation of certain characters as being specific is unwarranted, since sibling species may be more similar than different subspecies of the same species. Many Recent and fossil brachiopod genera are too narrow in definition owing to oversplitting or to a narrow conception of monophyly. I advocate somewhat broader and more practical genera for obtaining the maximal information value from such taxa. Brachiopods, contrary to popular belief, are an abundant and viable group in the southern hemisphere faunas. Most brachiopods in the Ross Sea appear to have definite niches and habitats but may overlap geographically where population densities are low. Brachiopods here can be divided roughly into a slope and a shelf assemblage. The greatest species diversity occurs at the seaward edge of the Ross Sea shelf, interpreted as an ecotone effect where two different water types meet. Only South America and Antarctica appear to have or have had direct communication between some elements of their brachiopod faunas. Other similarities between separate southern continents are related to retention of common pre-Cenozoic elements or to chance dispersal of larvae across barriers. Events related to cooling during the late Pliocene or Pleistocene caused reduction of puncta density, shell thickness, and spiculation in the Recent fauna and apparently influenced the present species structure, at least in Liothyrella uva, Gyrothyris mawsoni, and Macandrevia.

Download or read book Biology and Evolution of the Mollusca Volume 1 written by Winston Frank Ponder and published by CRC Press. This book was released on 2019-11-18 with total page 1524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molluscs comprise the second largest phylum of animals (after arthropods), occurring in virtually all habitats. Some are commercially important, a few are pests and some carry diseases, while many non-marine molluscs are threatened by human impacts which have resulted in more extinctions than all tetrapod vertebrates combined. This book and its companion volume provide the first comprehensive account of the Mollusca in decades. Illustrated with hundreds of colour figures, it reviews molluscan biology, genomics, anatomy, physiology, fossil history, phylogeny and classification. This volume includes general chapters drawn from extensive and diverse literature on the anatomy and physiology of their structure, movement, reproduction, feeding, digestion, excretion, respiration, nervous system and sense organs. Other chapters review the natural history (including ecology) of molluscs, their interactions with humans, and assess research on the group. Key features of both volumes: up to date treatment with an extensive bibliography; thoroughly examines the current understanding of molluscan anatomy, physiology and development; reviews fossil history and phylogenetics; overviews ecology and economic values; and summarises research activity and suggests future directions for investigation. Winston F Ponder was a Principal Research Scientist at The Australian Museum in Sydney where he is currently a Research Fellow. He has published extensively over the last 55 years on the systematics, evolution, biology and conservation of marine and freshwater molluscs, as well as supervised post graduate students and run university courses. David R. Lindberg is former Chair of the Department of Integrative Biology, Director of the Museum of Paleontology, and Chair of the Berkeley Natural History Museums, all at the University of California. He has conducted research on the evolutionary history of marine organisms and their habitats on the rocky shores of the Pacific Rim for more than 40 years. The numerous elegant and interpretive illustrations were produced by Juliet Ponder.
