Book excerpt: Although Charles Darwin's theory of evolution laid the foundations of modern biology, it did not tell the whole story. Most remarkably, The Origin of Species said very little about, of all things, the origins of species. Darwin and his modern successors have shown very convincingly how inherited variations are naturally selected, but they leave unanswered how variant organisms come to be in the first place. In Symbiotic Planet, renowned scientist Lynn Margulis shows that symbiosis, which simply means members of different species living in physical contact with each other, is crucial to the origins of evolutionary novelty. Ranging from bacteria, the smallest kinds of life, to the largest -- the living Earth itself -- Margulis explains the symbiotic origins of many of evolution's most important innovations. The very cells we're made of started as symbiotic unions of different kinds of bacteria. Sex -- and its inevitable corollary, death -- arose when failed attempts at cannibalism resulted in seasonally repeated mergers of some of our tiniest ancestors. Dry land became forested only after symbioses of algae and fungi evolved into plants. Since all living things are bathed by the same waters and atmosphere, all the inhabitants of Earth belong to a symbiotic union. Gaia, the finely tuned largest ecosystem of the Earth's surface, is just symbiosis as seen from space. Along the way, Margulis describes her initiation into the world of science and the early steps in the present revolution in evolutionary biology; the importance of species classification for how we think about the living world; and the way "academic apartheid" can block scientific advancement. Written with enthusiasm and authority, this is a book that could change the way you view our living Earth.
Book Synopsis The Nature of Symbiotic Stars by : M. Friedjung
Download or read book The Nature of Symbiotic Stars written by M. Friedjung and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many aspects of symbiotic stars have long puzzled astronomers. For instance while most students of the subject have considered them binary, many have at different times supported single star models. The nature of their outbursts is uncertain, while the dividing line between symbiotic stars and novae is unclear. In any case doubts can even be raised as to whether a class of "Symbiotic Stars" really exists. Much new data has been obtained in recent years, in particular from the study of radiation outside the visual region. Many symbiotic stars have been studied in the UV with IUE since 1978, while X-rays were det ected in a few cases with the Einstein satellite. There have been a num ber of infrared and radio studies, and the number of known symbiotic stars has also considerably increased. Furthermore theoretical ideas have in recent years been considerably enriched by concepts of stellar winds, and accretion phenomena in binaries including accretion disks. It was there fore extremely opportune and timely to hold the first international meet ing exclusively devoted to these stars, so as to consider the new results from such a wide range of observations in different spectral regions, and the conclusions which can be drawn for possible models as well as theories of the nature and structure of symbiotic stars. After a session devoted to new observations in different spectral regions, a session was spent considering some individual stars.
Book Synopsis An Introduction to Close Binary Stars by : R. W. Hilditch
Download or read book An Introduction to Close Binary Stars written by R. W. Hilditch and published by Cambridge University Press. This book was released on 2001-03-12 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Binary systems of stars are as common as single stars. They are of fundamental importance because they allow stellar masses, radii and luminosities to be measured directly, and explain a host of diverse and energetic phenomena including X-ray binaries, cataclysmic variables, novae, symbiotic stars, and some types of supernovae. This 2001 book was the first to provide a pedagogical and comprehensive introduction to binary stars. It combines theory and observations at all wavelengths to develop a unified understanding of binaries of all categories. It comprehensively reviews methods for calculating orbits, the Roche model, ideas about mass exchange and loss, methods for analysing light curves, the masses and dimensions of different binary systems, and imaging the surfaces of stars and accretion structures. This book provides a thorough introduction to the subject for advanced undergraduate and graduate students. Researchers will also find this to be an authoritative reference.
Book Synopsis The Symbiotic Stars by : S. J. Kenyon
Download or read book The Symbiotic Stars written by S. J. Kenyon and published by Cambridge University Press. This book was released on 1986-12-18 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dr Kenyon has researched and assembled here all the existing data for the known symbiotic stars, in which a dwarf star accretes material from its red giant companion. In this book he summarises observational material covering the eruptive and quiescent phases of these objects, and emphasises the important astrophysical problems raised and resolved by results at infrared, optical, radio, ultraviolet and X-ray wavelengths. Physical models for the eruptive and quiescent phases and the long-term evolution of symbiotic stars are discussed, with the goal of developing observational diagnostics that serve to test the basic theories. The book concludes with a detailed appendix and bibliography that will aid researchers interested in the history of individual symbiotic systems and confirm this volume as an indispensable handbook at any observatory where research on stellar objects in undertaken.
Book Synopsis The Symbiotic Habit by : Angela E. Douglas
Download or read book The Symbiotic Habit written by Angela E. Douglas and published by Princeton University Press. This book was released on 2021-08-10 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the natural world, organisms have responded to predators, inadequate resources, or inclement conditions by forming ongoing mutually beneficial partnerships--or symbioses--with different species. Symbiosis is the foundation for major evolutionary events, such as the emergence of eukaryotes and plant eating among vertebrates, and is also a crucial factor in shaping many ecological communities. The Symbiotic Habit provides an accessible and authoritative introduction to symbiosis, describing how symbioses are established, function, and persist in evolutionary and ecological time. Angela Douglas explains the evolutionary origins and development of symbiosis, and illustrates the principles of symbiosis using a variety of examples of symbiotic relationships as well as nonsymbiotic ones, such as parasitic or fleeting mutualistic associations. Although the reciprocal exchange of benefit is the key feature of symbioses, the benefits are often costly to provide, causing conflict among the partners. Douglas shows how these conflicts can be managed by a single controlling organism that may selectively reward cooperative partners, control partner transmission, and employ recognition mechanisms that discriminate between beneficial and potentially harmful or ineffective partners. The Symbiotic Habit reveals the broad uniformity of symbiotic process across many different symbioses among organisms with diverse evolutionary histories, and demonstrates how symbioses can be used to manage ecosystems, enhance food production, and promote human health.

Download or read book Pulsating Stars written by Márcio Catelan and published by John Wiley & Sons. This book was released on 2015-03-23 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book surveys our understanding of stars which change in brightness because they pulsate. Pulsating variable stars are keys to distance scales inside and beyond the Milky Way galaxy. They test our understanding not only of stellar pulsation theory but also of stellar structure and evolution theory. Moreover, pulsating stars are important probes of the formation and evolution of our own and neighboring galaxies. Our understanding of pulsating stars has greatly increased in recent years as large-scale surveys of pulsating stars in the Milky Way and other Local Group galaxies have provided a wealth of new observations and as space-based instruments have studied particular pulsating stars in unprecedented detail.

Book Synopsis Symbiosis as a Source of Evolutionary Innovation by : Lynn Margulis
Download or read book Symbiosis as a Source of Evolutionary Innovation written by Lynn Margulis and published by MIT Press. This book was released on 1991 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis, supplemented by the gradual accumulation of heritable mutation, results in the origin of new species and morphological novelty.A departure from mainstream biology, the idea of symbiosis--as in the genetic and metabolic interactions of the bacterial communities that became the earliest eukaryotes and eventually evolved into plants and animals--has attracted the attention of a growing number of scientists.These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis, supplemented by the gradual accumulation of heritable mutation, results in the origin of new species and morphological novelty. They include reports of current research on the evolutionary consequences of symbiosis, the protracted physical association between organisms of different species. Among the issues considered are individuality and evolution, microbial symbioses, animal-bacterial symbioses, and the importance of symbiosis in cell evolution, ecology, and morphogenesis. Lynn Margulis, Distinguished Professor of Botany at the University of Massachusetts at Amherst, is the modern originator of the symbiotic theory of cell evolution. Once considered heresy, her ideas are now part of the microbiological revolution. ContributorsPeter Atsatt, Richard C. Back, David Bermudes, Paola Bonfante-Fasolo, René Fester, Lynda J.

Written for graduate students, professional astronomers and researchers who want to start working in this field, this book is a practical guide to x-ray astronomy. The handbook begins with x-ray optics, basic detector physics and CCDs, before focussing on data analysis. It introduces the reduction and calibration of x-ray data, scientific analysis, archives, statistical issues and the particular problems of highly extended sources. The book describes the main hardware used in x-ray astronomy, emphasizing the implications for data analysis. The concepts behind common x-ray astronomy data analysis software are explained. The appendices present reference material often required during data analysis.
Book Synopsis Stars and Their Spectra by : James B. Kaler
Download or read book Stars and Their Spectra written by James B. Kaler and published by Cambridge University Press. This book was released on 1997-03-27 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of stars and their spectra is central to an understanding of classical and modern astronomy. The principal tool for investigating the nature of stars is to observe and interpret their spectra. In this lucid book, James Kaler clearly explains the alphabet of stellar astronomy - from the cool M stars to hot O stars - and tells the story of the evolution of stars and their place in the Universe. Before embarking on a fascinating voyage of cosmic discovery, we are introduced to the fundamental properties of stars, and how they can be categorised. Next, the structure of atoms and the formation of spectra is discussed, as a prelude to a full description of the spectral classification itself. The heart of the book examines each star type in turn and explores their spectra in detail. Notable discoveries and features related to each class sustain the story. There is also a review of unusual stars that cannot easily be classified. Finally, the book closes with a skilful integration of all the data - tracing the paths of birth, life and death of stars on the Hertzsprung-Russell diagram. This book is based on a widely acclaimed series of articles on stellar astronomy which appeared in the magazine Sky and Telescope. It provides an invaluable introduction for observers and students.
Book Synopsis RS Ophiuchi (2006) and the Recurrent Nova Phenomenon by : Aneurin Evans
Download or read book RS Ophiuchi (2006) and the Recurrent Nova Phenomenon written by Aneurin Evans and published by . This book was released on 2008 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: "On 12 February 2006, the recurrent nova RS Ophiuchi erupted for the first time since 1985, its 6th (at least!) known eruption. This event triggered an intensive multi-wavelength observational campaign, from the radio to gamma-rays, and theoreticians have been presented with a wealth of high-quality data. A workshop was held at Keele University, UK, from 12-14 June 2007 to discuss the observations, their interpretation, and where RS Ophiuchi sits in the wider astrophysical picture. The workshop brought together observers, from gamma-ray to radio wavelengths, theoreticians, and workers in closely related areas. The workshop considered not only the 2006 eruption of RS Oph but also the implications that this has had for our understanding of other much broader areas of astrophysics. It was wide ranging, taking in the environments of red giants; supernova progenitors; accretion, thermonuclear processes and evolution of close binary systems; and shocks of jets, as well as recurrent novae and related objects. The proceedings contain 15 invited reviews, 38 contributed talks and posters, and 3 specially commissioned papers which we hope will enhance the value of the workshop for the wider astrophysical community."--Publisher's website
Book Synopsis The Symbiotic Phenomenon by : Joanna Mikolajewska
Download or read book The Symbiotic Phenomenon written by Joanna Mikolajewska and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Symbiotic stars were identified spectroscopically as M giants with a very strong He II 4686 emission line. After five decades of study by many astronomers, the first internatioinal meetings devoted to symbiotics were held at the University of Colorado (Boulder) and at the Haute Provence Observatory during the Summer of 1981. These conferences emphasized exciting new results obtained by modern satellite (EINSTEIN, IUE) and ground-based observatories. Although the vast majority of the participants were already fairly sure that symbiotics are almost certainly interacting binary systems, and not extremely peculiar single stars, it was not clear exactly which types of physical processes were needed to be invoked to explain their observed behaviour. Many were even worried that it might not be possible to clearly define a class of "symbiotic stars" , and thus establish a unique model applicable to any system. Since the publication of the Haute-Provence proceedings, our understanding of the physical processes occuring in symbiotic stars (and in related objects such as cataclysmic variables and compact planetary nebulae) has greatly improved. We now speak confidently of a "symbiotic phenomenon" , in which an evolved red giant and a hot companion object (usually thought to be an accreting main sequence star or a luminous white dwarf star) happily coexist.
