Hardback. Condizione: New. Sea anemones are among the most ancient of living metazoans. Long a paradigm of the "elementary nervous system" and constructional simplicity, sea anemones have been favourite experimental subjects in behavioural neurophysiology and in biomechanics. Their unique nematocyst toxins are used to study the sodium and calcium channels in excitable membranes, and their agonistic interactions provide insights into the evolution of allororecognition systems. Incorporation of algal endosymbionts by some of these animals combines in a single unit both primary producer and consumer, and provides a tight recycling of scarce nutrients between host and symbiont. Many species include vegetative proliferation or parthogenesis in their life cycle and are important organisms in the study of the evolutionary potential and adaptive demography of co-ordinated clonal growth and bisexual reproductive strategies. The ability of clonal anemones to recognize members of different clones upon contact provides insight into the evolution of immune systems. This book provides an introduction and synthesis of the biology of sea anemones.The text is cross-referenced and integrated, and together with a bibliography, should be valuable to those interested in the physiology, ecology, biochemistry, behaviour, population biology and evolution of this group of marine invertebrates. This book should be of interest to marine biologists, ecologists and zoologists with a general interest in themes such as symbiosis and life cycles.…

No Binding. Condizione: Very Good. 1st Edition. Very rare original declassified technical study under US Air Force contract at the beginning of the project which, in 1957, resulted in Atlas, the first Intercontinental Ballistic Missile. Atlas would later become the launch vehicle that sent the first four Mercury astronauts into space. Signed by the Convair author and by Ralph H. Shick, Convair Chief of Aerodynamics. San Diego: General Dynamics/Convair [Consolidated Vultee Aircraft], December 30, 1954. Unbound pages, produced on a special paper using an early form of photocopying. 32 pages total, including 15 pages of rocket diagrams and graphs. Originally classified Confidential, with 1967 declassification stamp. Declassification marks smeared on front cover, illustration pages with punched holes at spine. Overall, in very good condition.…
