Available in PDF, EPUB and Kindle. Book excerpt: One of the privileges of appointment to a Chair at another University is that it gives one the right to talk to many distinguished people about their work and ideas. E. B. Ford was known to me before I came to Oxford as the author of a book on butterflies and as somewhat of an eccentric, but I was quite unprepared for the welcome he gave me into the Department of Zoology and for the enormous interest of the subject which he gradually revealed to me. My contact with the Genetics Laboratory was made easier by one of the first things I had to do. Within a few weeks of my arrival, it came to light that a new building for another department was to be erected on a piece of land, known to us as 'Henry's weed garden' but generally regarded as being derelict. Even my, at that time, elementary, knowledge of ecological genetics made it easy to realize that the population of caterpillars that had been under continuous observation there for eleven years put it in a rather special category of wilderness; although I did not succeed in saving it, I was able to persuade the university to substitute another experimental plot and this may have helped the geneticists to appreciate that the new professor was not only interested in electrical apparatus.

Download or read book Breeding Fodder Crops for Marginal Conditions written by O.A. Rognli and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains papers and posters presented at the 18th Eucarpia Fodder Crops Section Meeting held at Loen, Nordfjord, Norway in August 1993. In most environments some form of marginal conditions or stress prevails. Few crops are being produced under such a wide range of environmental and management stresses as fodder crops. Improved adaptation of fodder crops to marginal conditions is crucial in developing sustainable, low-input agricultural systems. The book is unique in demonstrating the large diversity both in crops and environmental stresses that confront the forage breeders. Both general and specific aspects of adaptation to marginal growing conditions are presented, ranging from problems caused by snow and ice in the Subarctic regions of Europe to the severe drought problems in the Mediterranean regions. For everyone involved in studies of adaptation and breeding of perennial plants for marginal conditions or stress environments.
Download or read book Genetics of Flowering Plants written by Verne Grant and published by Columbia University Press. This book was released on 1975 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gore Vidal, known for such best-sellers as The City and the Pillar, Burr, Lincoln, and Myra Breckinridge, is a household name. The controversial Vidal ran for Congress in 1960, and set sparks flying with his public debates challenging William F. Buckley and Norman Mailer. Although one of America's most admired and prolific writers, Vidal has been steadfastly ignored or impugned by many critics. This is partly owing to the vast scope of his writings, which include more than twenty novels, half a dozen plays, dozens of screenplays, countless essays and book reviews, political commentary, and short stories; how do the critics approach such a writer? There has also been backlash against Vidal, whose radical polemics and undisguised contempt for those whom he has called "the hacks and hicks of academe" have hardly endeared him to the critical establishment. Gore Vidal: Writer Against the Grain is the first collection of critical essays to approach this important American writer in an attempt to rectify the unwarranted underestimation of his work. Jay Parini has drawn from the best of previously published criticism and commissioned fresh articles by leading contemporary critics to construct a comprehensive portrait of Vidal's multifaceted and memorable career. Writers as diverse as Harold Bloom, Stephen Spender, Catharine R. Stimpson, Richard Poirier, and Italo Calvino examine Vidal's work in their own highly individual ways, and each finds a different Vidal to celebrate, chide, recollect, or view close up. Also included is a recent interview with Parini in which Vidal discusses his career and his troubled relationship with the reviewers.The Vidal that finally emerges from these essays is a writer of undeniable weight and importance. As readers will agree, Gore Vidal: Writer Against the Grain establishes his rightful role as one of the premier novelists and leading critical observers of this century.
Download or read book The Accidental Homo Sapiens written by Ian Tattersall and published by Simon and Schuster. This book was released on 2019-04-02 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: What happens now that human population has outpaced biological natural selection? Two leading scientists reveal how we became who we are—and what we might become. When we think of evolution, the image that likely comes to mind is the iconic, straight-forward image of a primate morphing into a human being. Yet random events have played huge roles in determining the evolutionary histories of everything from lobsters to humans. However, random genetic novelties are most likely to "stick" in small populations. It is mathematically unlikely to happen in large ones. With our enormous and seemingly inexorably expanding population, humanity has fallen under the influence of the famous (or infamous) “bell curve.” This revelatory new book explores what the future of our species could hold, while simultaneously revealing what we didn’t become—and what we won’t become. A cognitively unique species, our actions fall on a bell curve as well. Individuals may be saintly or evil, narrow-minded or visionary. But it is possible not just for the species, but for a person to be all of these things—even in a single day. We all fall somewhere within the giant hyperspace of the human condition that these curves describe. The Accidental Homo Sapiens shows readers that though humanity now exists on this bell curve, we are far from a stagnant species. Tattersall and DeSalle reveal how biological evolution in modern humans has given way to a cultural dynamic that is unlike anything else the Earth has ever witnessed, and that will keep life interesting—perhaps sometimes too interesting—for as long as we exist on this planet.

Download or read book Engineering the Environment written by David P. D. Munns and published by University of Pittsburgh Press. This book was released on 2017-07-19 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Promising an end to global hunger and political instability, huge climate-controlled laboratories known as phytotrons spread around the world to thirty countries after the Second World War. The United States built nearly a dozen, including the first at Caltech in 1949. Made possible by computers and other novel greenhouse technologies of the early Cold War, phytotrons enabled plant scientists to experiment on the environmental causes of growth and development of living organisms. Subsequently, they turned biologists into technologists who, in their pursuit of knowledge about plants, also set out to master the machines that controlled their environment. Engineering the Environment tells the forgotten story of a research program that revealed the shape of the environment, the limits of growth and development, and the limits of human control over complex technological systems. As support and funding for basic science dwindled in the mid-1960s, phytotrons declined and ultimately disappeared—until, nearly thirty years later, the British built the Ecotron to study the impact of climate change on biological communities. By revisiting this history of phytotrons, David Munns reminds us of the vital role they can play in helping researchers unravel the complexities of natural ecosystems in the Anthropocene.

Download or read book Sex and Evolution MPB 8 Volume 8 written by George Christopher Williams and published by Princeton University Press. This book was released on 2020-03-31 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the relationship between various types of reproduction and the evolutionary process. Starting with the concept of meiosis, George C. Williams states the conditions under which an organism with both sexual and asexual reproductive capacities will employ each mode. He argues that in low-fecundity higher organisms, sexual reproduction is generally maladaptive, and persists because there is no ready means of developing an asexual alternative. The book then considers the evolutionary development of diverse forms of sexuality, such as anisogamy, hermaphroditism. and the evolution of differences between males and females in reproductive strategy. The final two chapters examine the effect of genetic recombination on the evolutionary process itself.
Download or read book Ecological Speciation written by Patrik Nosil and published by OUP Oxford. This book was released on 2012-03-15 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origin of biological diversity, via the formation of new species, can be inextricably linked to adaptation to the ecological environment. Specifically, ecological processes are central to the formation of new species when barriers to gene flow (reproductive isolation) evolve between populations as a result of ecologically-based divergent natural selection. This process of 'ecological speciation' has seen a large body of particularly focused research in the last 10-15 years, and a review and synthesis of the theoretical and empirical literature is now timely. The book begins by clarifying what ecological speciation is, its alternatives, and the predictions that can be used to test for it. It then reviews the three components of ecological speciation and discusses the geography and genomic basis of the process. A final chapter highlights future research directions, describing the approaches and experiments which might be used to conduct that future work. The ecological and genetic literature is integrated throughout the text with the goal of shedding new insight into the speciation process, particularly when the empirical data is then further integrated with theory.

Beginning with a description of the processes of evolution in native and cultivated plants, the book reviews the origins of crop domestication and their subsequent development over time. All major crop species are discussed, including cereals, protein plants, starch crops, fruits and vegetables, from their origins to conservation of their genetic resources for future development.
Download or read book A Lab for All Seasons written by Sharon E. Kingsland and published by Yale University Press. This book was released on 2023-07-25 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first book to chronicle how innovation in laboratory designs for botanical research energized the emergence of physiological plant ecology as a vibrant subdiscipline Laboratory innovation since the mid-twentieth century has powered advances in the study of plant adaptation, evolution, and ecosystem function. The phytotron, an integrated complex of controlled-environment greenhouse and laboratory spaces, invented by Frits W. Went in the 1950s, set off a worldwide laboratory movement and transformed the plant sciences. Sharon Kingsland explores this revolution through a comparative study of work in the United States, France, Australia, Israel, the USSR, and Hungary. These advances in botanical research energized physiological plant ecology. Case studies explore the development of phytotron spinoffs such as mobile laboratories, rhizotrons, and ecotrons. Scientific problems include the significance of plant emissions of volatile organic compounds, symbiosis between plants and soil fungi, and the discovery of new pathways for photosynthesis as an adaptation to hot, dry climates. The advancement of knowledge through synthesis is a running theme: linking disciplines, combining laboratory and field research, and moving across ecological scales from leaf to ecosystem. The book also charts the history of modern scientific responses to the emerging crisis of food insecurity in the era of global warming.
