Available in PDF, EPUB and Kindle. Book excerpt: Effects of siphonophores on sound propagation in the sea were studied by determining the size of gas bubbles they contain and produce, and the times, volumes, and rates involved in these processes. Major findings were: (1) gases contained in fresh siphonophore floats are generally close to ambient pressure, suggesting release of many bubbles during vertical ascent; (2) oxygen consumption may be elevated during production of CO; (:) diffusion constants for siphonophore floats are close to those for chitin; (4) calculated energy requirements for countering hydrostatic pressures indicate that float refilling times are probably no more than a few hours.

Book excerpt: MacGregor is desperate to return home. Unfortunately, he's marooned in the Gulf of Darién, following independent Scotland's doomed colonisation attempt at the end of the 17th century. Worse still, he's a character in a novel whose author is dying, and he's running out of time. As the author's preoccupations, memories and spiralling thoughts start to pollute MacGregor's world, he finds his narrative eroding and his escape routes blocked. Desperately clinging to hope, MacGregor is determined to keep his Creator writing long enough to deliver him home. But will he be able to drive the story to its end before his Creator reaches theirs?

Download or read book Biological Identity written by Anne Sophie Meincke and published by Routledge. This book was released on 2020-08-25 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytic metaphysics has recently discovered biology as a means of grounding metaphysical theories. This has resulted in long-standing metaphysical puzzles, such as the problems of personal identity and material constitution, being increasingly addressed by appeal to a biological understanding of identity. This development within metaphysics is in significant tension with the growing tendency amongst philosophers of biology to regard biological identity as a deep puzzle in its own right, especially following recent advances in our understanding of symbiosis, the evolution of multi-cellular organisms and the inherently dynamical character of living systems. Moreover, and building on these biological insights, the broadly substance ontological framework of metaphysical theories of biological identity appears problematic to a growing number of philosophers of biology who invoke process ontology instead. This volume addresses this tension, exploring to what extent it can be dissolved. For this purpose, the volume presents the first selection of essays exclusively focused on biological identity and written by experts in metaphysics, the philosophy of biology and biology. The resulting cross-disciplinary dialogue paves the way for a convincing account of biological identity that is both metaphysically constructive and scientifically informed, and will be of interest to metaphysicians, philosophers of biology and theoretical biologists.
Download or read book Jellyfish written by Lisa-ann Gershwin and published by University of Chicago Press. This book was released on 2016-06-07 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: An introduction to these bizarre and beautiful creatures of the sea, filled with color photos and illustrations: “Fascinating.”—Boing Boing Jellyfish are the oldest multi-organed life form on the planet, having inhabited the ocean for more than five hundred million years. With their undulating umbrella-shaped bells and sprawling tentacles, they are compelling and gorgeous, strange and dangerous. In many places they’re also vastly increasing in number, and these population blooms may be an ominous indicator of the rising temperatures and toxicity of the oceans. Jellyfish presents these aquarium favorites in all their glory. Fifty unique species, from the purple people eater to black sea nettles, are presented in stunning photos along with the most current scientific information on their anatomy, history, distribution, position in the water, and environmental status. Foremost jellyfish expert Lisa-ann Gershwin provides an insightful look at the natural history and biology of each of these spellbinding creatures, plus a timely take on their place in the rapidly changing and deteriorating condition of the oceans. Learn about immortal jellyfish who live and die and live again—as well as those who camouflage themselves amid sea grasses and shells, hiding in plain sight. Discover the jellyfish that’s the world’s most venomous animal, and the jellyfish that helped scientists win the Nobel Prize. They’re all here and more in this delightful volume. “A thorough coverage of jellyfish history, biology and ecology. Gershwin, a marine biologist who has discovered over 200 new species of jellyfish, does an excellent job of combining a compelling narrative of 50 different jellyfish with luscious, I-can’t-believe-they’re-real photos.”—Boing Boing

Download or read book Antarctic Siphonophores From Plankton Samples of the United States Antarctic Research Program written by Angeles Alvarino and published by American Geophysical Union. This book was released on 1991-01-08 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 49. The distribution of Siphonophora of the Antarctic, Subantarctic, and adjacent regions of the Pacific and Atlantic Oceans is described. Specimens for this study were obtained during the United States Antarctic Research Program from USNS Eltanin cruises 3-5, 8-23, 25-28, 35, and 38 during spring, summer, fall, and winter. Samples were collected from 1962 to 1969, using open-closing and nonclosing plankton nets. Information is compiled on horizontal distributions of siphonophores in the South Atlantic Ocean west of 0°. Illustrations of the species, and maps of distribution at the three bathymetric levels, are also included. In addition, data on Eltanin cruise 30 are presented, covering mainly the Pacific tropical region during the summer, with some stations below the equator (austral winter). Vertical distributions of each species are discussed for the three bathymetric zones: epipelagic (200-0 m), mesopelagic (1000-200 m), and bathypelagic (below 1000 m). Life stages and seasonal variations are also considered. Eighty species of Siphonophora were identified in these collections. Among these, and described elsewhere, were five new species: Lensia eltanin, L. eugenioi, L. landrumae, Heteropyramis alcala, and Thalassophyes ferrarii. The eudoxid stages of L. lelouveteau and L. reticulata were also discovered. In addition, the following rare Siphonophora species were collected: Halistemma cupulifera, Desmophyes annectens, Lilyopsis rosea, Eudoxia macra, Lensia achilles, L. baryi, L. exeter, L. grimaldii, L. hostile, Nectocarmen antonioi, and Clausophyes galeata. The most common species of the Antarctic Subantarctic region during the four seasons was Dimophyes arctica. The eudoxid stages of Chelophyes appendiculata, Diphyes dispar, Diphyopsis mitra, Clausophyes ovata, and Heteropyramis maculata were abundant.
