Download or read book A History of Weed Science in the United States written by Robert L Zimdahl and published by Elsevier. This book was released on 2010-02-04 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is important that scientists think about and know their history - where they came from, what they have accomplished, and how these may affect the future. Weed scientists, similar to scientists in many technological disciplines, have not sought historical reflection. The technological world asks for results and for progress. Achievement is important not, in general, the road that leads to achievement. What was new yesterday is routine today, and what is described as revolutionary today may be considered antiquated tomorrow. Weed science has been strongly influenced by technology developed by supporting industries, subsequently employed in research and, ultimately, used by farmers and crop growers. The science has focused on results and progress. Scientists have been--and the majority remain--problem solvers whose solutions have evolved as rapidly as have the new weed problems needing solutions. In a more formal sense, weed scientists have been adherents of the instrumental ideology of modern science. That is an analysis of their work, and their orientation reveals the strong emphasis on practical, useful knowledge; on know how. The opposite, and frequently complementary orientation, that has been missing from weed science is an emphasis on contemplative knowledge; that is, knowing why. This book expands on and analyzes how these orientations have affected weed science’s development. The first analytical history of weed science to be written Compares the development of weed science, entomology and plant pathology Identifies the primary founders of weed science and describes their role

Available in PDF, EPUB and Kindle. Book excerpt: “Pollan shines a light on our own nature as well as on our implication in the natural world.” —The New York Times “A wry, informed pastoral.” —The New Yorker The book that helped make Michael Pollan, the New York Times bestselling author of How to Change Your Mind, Cooked and The Omnivore’s Dilemma, one of the most trusted food experts in America Every schoolchild learns about the mutually beneficial dance of honeybees and flowers: The bee collects nectar and pollen to make honey and, in the process, spreads the flowers’ genes far and wide. In The Botany of Desire, Michael Pollan ingeniously demonstrates how people and domesticated plants have formed a similarly reciprocal relationship. He masterfully links four fundamental human desires—sweetness, beauty, intoxication, and control—with the plants that satisfy them: the apple, the tulip, marijuana, and the potato. In telling the stories of four familiar species, Pollan illustrates how the plants have evolved to satisfy humankind’s most basic yearnings. And just as we’ve benefited from these plants, we have also done well by them. So who is really domesticating whom?

Download or read book Parthenium Weed written by Stephen W Adkins and published by CABI. This book was released on 2018-11-07 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the most important aspects of the biology, ecology and management of what is one of the world's worst weeds. Originally regarded as a major weed in Australia and India, Parthenium weed is now widespread in around 48 countries in Africa, Asia and the South Pacific, and has the potential to spread to new countries in Africa, Asia and Europe. This book, which is a collective effort by 27 members of the International Parthenium Weed Network, addresses research and knowledge gaps for different countries. It examines the weed's mode of spread, its impact on agricultural production, its effect on the environment and on human health, and its management using biological control, as well as cultural, physical and chemical approaches. It also considers the coordination of the weed's management, possible uses for Parthenium weed, its present distribution and how this is impacted by climate change. This book includes: A detailed analysis of Parthenium weed biology. Experiences with Parthenium weed worldwide. An explanation of practical management options. This book will be of interest to graduate students and researchers in universities and institutes, in the fields of plant ecology, botany, agriculture, conservation and restoration ecology.

Download or read book Black 47 and Beyond written by Cormac Ó Gráda and published by Princeton University Press. This book was released on 2020-09-01 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here Ireland's premier economic historian and one of the leading authorities on the Great Irish Famine examines the most lethal natural disaster to strike Europe in the nineteenth century. Between the mid-eighteenth and early-nineteenth centuries, the food source that we still call the Irish potato had allowed the fastest population growth in the whole of Western Europe. As vividly described in Ó Gráda's new work, the advent of the blight phytophthora infestans transformed the potato from an emblem of utility to a symbol of death by starvation. The Irish famine peaked in Black '47, but it brought misery and increased mortality to Ireland for several years. Central to Irish and British history, European demography, the world history of famines, and the story of American immigration, the Great Irish Famine is presented here from a variety of new perspectives. Moving away from the traditional narrative historical approach to the catastrophe, Ó Gráda concentrates instead on fresh insights available through interdisciplinary and comparative methods. He highlights several economic and sociological features of the famine previously neglected in the literature, such as the part played by traders and markets, by medical science, and by migration. Other topics include how the Irish climate, usually hospitable to the potato, exacerbated the failure of the crops in 1845-1847, and the controversial issue of Britain's failure to provide adequate relief to the dying Irish. Ó Gráda also examines the impact on urban Dublin of what was mainly a rural disaster and offers a critical analysis of the famine as represented in folk memory and tradition. The broad scope of this book is matched by its remarkable range of sources, published and archival. The book will be the starting point for all future research into the Irish famine.

Download or read book The Cosmic Oasis written by Mark Williams and published by Oxford University Press. This book was released on 2022-05-26 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alone in the known universe the Earth glows bright with life, a unique cosmic oasis of biodiversity which is now under threat from our own actions. The Earth is a unique as a living planet, a cosmic oasis drifting in the vastness of barren space. It is strikingly and obviously different from our nearest heavenly neighbours, the Moon, Venus and Mars, in its thin skin of biology, extending from the surface for a few kilometres into the crust, and for a few tens of kilometres into the air. But how did this remarkable abundance and diversity of life arise? How has life survived over the enormous time frame of Earth's history? And does it continue to flourish now, especially with the growing pressure for space from humans? The Cosmic Oasis examines life on Earth, from our earliest interactions with animals and plants to our absolute domination of biology. It follows our developing understanding of life's origins, its remarkable complexity, and its interactions with the air, oceans and land. It also shows how patterns of diversity across the surface of the planet evolved, and how humans are now homogenising these, degrading both biodiversity and the space in which life can exist. Within this overall trend of loss there are some remarkable examples of survival, from the beneficial relationships between the gelada monkeys and wolves of the Ethiopian highlands, and the people and brown howler monkeys of Porte Allegre in Brazil, to interactions between you and your gut microbiome. Thoughout, the authors ask what these interactions can teach us about building a better relationship with nature, and consider how we might become stewards, rather than destructive exploiters, of the life around us.

Download or read book The Anthropocene written by Julia Adeney Thomas and published by John Wiley & Sons. This book was released on 2020-10-06 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans rank with the powerful forces of nature transforming Earth. Since the mid-20th century, population growth, industrialization, and globalization have had such deep and wide-ranging impacts that our planet no longer functions as it did during the previous eleven millennia. So distinctive is this collective human intervention that a new geological interval has been proposed; it is called the Anthropocene. The Anthropocene is intriguing scientifically, fascinating intellectually, and deeply disturbing politically, socially, economically, and ethically. We must learn how to co-exist sustainably with the rest of nature in what is emerging as a new planetary state. To do so, we must first understand what "Anthropocene" means in all its dimensions. This book adopts a multidisciplinary approach, starting with an exploration of the Anthropocene as a geological concept: ranging across the physical changes to the landscape, to the rapidly heating climate, to a biosphere undergoing transformation. And what of the "anthropos" in the Anthropocene? While geoscience does not normally address political and ethical issues of justice and equity, or economics and culture, Anthropocene studies in the humanities and social sciences investigate the complexities of the human activity driving global change. Here the book looks at human history, both in the deep past and more recently, the politics and economics of growth spurring the Anthropocene, and potential ways of mitigating its cruel effects. Our fragile, still beautiful, planet is finite. The new realities of the Anthropocene will need our best efforts, across disciplinary divides, at effective hope and action.

Download or read book Around the World in 80 Species written by Jill Atkins and published by Routledge. This book was released on 2018-11-08 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world is currently experiencing a sixth period of mass species extinction, and extinction of flora and fauna is caused by a variety of factors arising from industrial activity and increasing human population, such as global warming, climate change, habitat loss, pollution and use of pesticides. Most causes of extinction are linked to corporate activity, either directly or indirectly. Around the World in 80 Species: Exploring the Business of Extinction responds to the ongoing mass extinction crisis engulfing our planet by exploring the ways in which accounting, business and finance can be used to prevent species extinctions. From Africa to the Far East and from Europe to the Americas, the authors explore species loss and how businesses can stop mass extinctions through greater transparency, and through closer engagement with their investors and wildlife organisations. The book concludes that global capitalism has led us to this extinction crisis and that therefore the mechanisms of capitalism – namely accounting, finance, investment – can help to pull us out. Businesses must urgently address extinction before it is too late for all species, including ourselves. As the first book to explore corporate accounting and accountability in relation to species on the brink of extinction, this book will be of great interest to both professionals and a wider audience interested in the causes and prevention of extinction.

Book excerpt: EXILED FROM IMMORTALITY!The third entry in McCarthy's groundbreaking, mind-bending Queendom of Sol series back in print. Brash and idealistic, they were rebels without a cause in a world governed by science, reason . . . and immortality. Banished for their troubles to the starship Newhope, they now face a bold future: to settle the worlds of Barnard’s Star. Now King Bascal Edward de Towaji Lutui, former prince of the Queendom of Sol, together with Captain Xiomara “Xmary” Li Weng and her lover, first mate Conrad Mursk, face a perilous voyage with thousands of their fellow exiles. The journey will last a century, but with Queendom technology it’s no problem to step into a fax machine and “print” a fresh, youthful version of yourself. But what this crew of rebels will find is far from the paradise they seek. Before long, their optimistic young colony has started to show signs of strain. And worst of all, death itself has returned with a vengeance.
