Book excerpt: Where do camels belong? In the Arab world may seem the obvious answer, but they are relative newcomers there. They evolved in North America, retain their greatest diversity in South America, and the only remaining wild dromedaries are in Australia. This is a classic example of the contradictions of 'native' and 'invasive' species, a hot issue right now, as the flip-side of biodiversity. We have all heard the horror stories of invasives, from Japanese knotweed that puts fear into the heart of gardeners to brown tree snakes that have taken over the island of Guam. But do we need to fear invaders? And indeed, can we control them, and do we choose the right targets? Ken Thompson puts forward a fascinating array of narratives to explore what he sees as the crucial question - why only a minority of introduced species succeed, and why so few of them go on to cause trouble. He discusses, too, whether our fears could be getting in the way of conserving biodiversity, and responding to the threat of climate change.

Download or read book Where Do Camels Belong written by Ken Thompson and published by Greystone Books. This book was released on 2014-09-13 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ecologist and author of Do We Need Pandas? “presents a stimulating challenge to our perceptions of nature” and non-native species (George Monbiot). You may be surprised to learn that camels evolved and lived for tens of millions of years in North America—and also that the leek, national symbol of Wales, was a Roman import to Britain, as were chickens, rabbits and pheasants. These classic examples highlight the issues of “native” and “invasive” species. We have all heard the horror stories of invasives wreaking havoc on ecosystems. But do we need to fear invaders? In this controversial book, Ken Thompson asks: Why do very few introduced species succeed, why do so few of them go on to cause trouble, and what is the real cost of invasions? He also discusses whether fear of invasive species could be getting in the way of conserving biodiversity and responding to climate change.
Download or read book Camels in Asia and North Africa written by Eva-Maria Knoll and published by Austrian Academy of Sciences Press. This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humanity's history is closely linked to those of camels. Without these remarkable animals we could not have inhabited the arid zones of Asia and North Africa, nor could we cope with today's challenges of increasing desertification. Researching interactions between humans and camels therefore has been established at the Austrian Academy of Sciences ever since its foundation more than 160 years ago. The present publication is committed to this research tradition. This book assembles insights upon current and historical interactions between humans and camels. Thereby it is international and interdisciplinary from the outset and aims at intensifying a camel-related knowledge exchange between the natural sciences and the humanities. The here presented discussions of Old World camels (dromedary, Bactrian, wild camel) include such diverse topics as camel origin, domestication, breeding, raising and commerce. Moreover, camels' significance is also discussed regarding socio-cultural and economic factors, music, folk medicine and veterinary medicine, as well as saving the last remaining wild camels. With an afterword by Richard W. Bulliet (New York), one of the world's leading authorities on the camels' history.
Download or read book Darwin s Most Wonderful Plants written by Ken Thompson and published by University of Chicago Press. This book was released on 2019-10-07 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many people, the story of Charles Darwin goes like this: he ventured to the Galapagos Islands on the Beagle, was inspired by the biodiversity of the birds he saw there, and immediately returned home to write his theory of evolution. But this simplified narrative is inaccurate and lacking: it leaves out a major part of Darwin’s legacy. He published On the Origin of Species nearly thirty years after his voyages. And much of his life was spent experimenting with and observing plants. Darwin was a brilliant and revolutionary botanist whose observations and theories were far ahead of his time. With Darwin’s Most Wonderful Plants, biologist and gardening expert Ken Thompson restores this important aspect of Darwin’s biography while also delighting in the botanical world that captivated the famous scientist. Thompson traces how well Darwin’s discoveries have held up, revealing that many are remarkably long-lasting. Some findings are only now being confirmed and extended by high-tech modern research, while some have been corrected through recent analysis. We learn from Thompson how Darwin used plants to shape his most famous theory and then later how he used that theory to further push the boundaries of botanical knowledge. We also get to look over Darwin’s shoulder as he labors, learning more about his approach to research and his astonishing capacity for hard work. Darwin’s genius was to see the wonder and the significance in the ordinary and mundane, in the things that most people wouldn’t look at twice. Both Thompson and Darwin share a love for our most wonderful plants and the remarkable secrets they can unlock. This book will instill that same joy in casual gardeners and botany aficionados alike.

Download or read book Do We Need Pandas written by Ken Thompson and published by Bloomsbury Publishing. This book was released on 2011-05-28 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: How much do we really know about the species that make up the natural world? All over the world, biodiversity is gravely threatened – by overfishing, habitat destruction, pollution and climate change. Yet life on Earth has previously experienced five episodes of mass extinction, and nature has repeatedly proved itself to be a resilient, regenerative force. In this fascinating book, ecologist Dr. Ken Thompson surveys the Earth's biodiversity, its origins and some of the threats it currently faces. Thought-provoking and deeply engaging, Do We Need Pandas? offers a non-technical overview of our ecosystems and expands on the causes and consequences of biodiversity loss. Importantly, it also examines what we should be doing to secure the survival not only of the species with which we share the planet, but of ourselves – and whether we need to be more concerned about ecosystems as a whole than about iconic species such as the orangutan and giant Panda.
Download or read book Cumin Camels and Caravans written by Gary Paul Nabhan and published by University of California Press. This book was released on 2020-09-22 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gary Paul Nabhan takes the reader on a vivid and far-ranging journey across time and space in this fascinating look at the relationship between the spice trade and culinary imperialism. Drawing on his own family’s history as spice traders, as well as travel narratives, historical accounts, and his expertise as an ethnobotanist, Nabhan describes the critical roles that Semitic peoples and desert floras had in setting the stage for globalized spice trade. Traveling along four prominent trade routes—the Silk Road, the Frankincense Trail, the Spice Route, and the Camino Real (for chiles and chocolate)—Nabhan follows the caravans of itinerant spice merchants from the frankincense-gathering grounds and ancient harbors of the Arabian Peninsula to the port of Zayton on the China Sea to Santa Fe in the southwest United States. His stories, recipes, and linguistic analyses of cultural diffusion routes reveal the extent to which aromatics such as cumin, cinnamon, saffron, and peppers became adopted worldwide as signature ingredients of diverse cuisines. Cumin, Camels, and Caravans demonstrates that two particular desert cultures often depicted in constant conflict—Arabs and Jews—have spent much of their history collaborating in the spice trade and suggests how a more virtuous multicultural globalized society may be achieved in the future.

Download or read book Tickets for the Ark written by Rebecca Nesbit and published by Profile Books. This book was released on 2022-02-17 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: A NEW SCIENTIST BOOK OF THE YEAR 2022 'A fascinating read for anyone interested in the future of the planet' Adam Hart, author and BBC science presenter Our planet hasn't seen the current rate of extinction since the demise of the dinosaurs 65 million years ago, and global conservation efforts are failing to halt this. As a society, we face choices which will determine the fate of Earth's estimated 8.7 million species, including humans. As wildlife declines, conservation needs to make trade-offs. But what should we conserve and why? Are we wrong to love bees and hate wasps? Are native species more valuable than newcomers (aka invasives)? Should some animals be culled to protect others, and what do we want the 'natural world' to look like? There are many surprising answers in Rebecca Nesbit's lively, stimulating book, which sows the seeds of a debate we urgently need to have.
Download or read book The New Wild written by Fred Pearce and published by Beacon Press. This book was released on 2016-04-05 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Named one of the best books of 2015 by The Economist A provocative exploration of the “new ecology” and why most of what we think we know about alien species is wrong For a long time, veteran environmental journalist Fred Pearce thought in stark terms about invasive species: they were the evil interlopers spoiling pristine “natural” ecosystems. Most conservationists and environmentalists share this view. But what if the traditional view of ecology is wrong—what if true environmentalists should be applauding the invaders? In The New Wild, Pearce goes on a journey across six continents to rediscover what conservation in the twenty-first century should be about. Pearce explores ecosystems from remote Pacific islands to the United Kingdom, from San Francisco Bay to the Great Lakes, as he digs into questionable estimates of the cost of invader species and reveals the outdated intellectual sources of our ideas about the balance of nature. Pearce acknowledges that there are horror stories about alien species disrupting ecosystems, but most of the time, the tens of thousands of introduced species usually swiftly die out or settle down and become model eco-citizens. The case for keeping out alien species, he finds, looks increasingly flawed. As Pearce argues, mainstream environmentalists are right that we need a rewilding of the earth, but they are wrong if they imagine that we can achieve that by reengineering ecosystems. Humans have changed the planet too much, and nature never goes backward. But a growing group of scientists is taking a fresh look at how species interact in the wild. According to these new ecologists, we should applaud the dynamism of alien species and the novel ecosystems they create. In an era of climate change and widespread ecological damage, it is absolutely crucial that we find ways to help nature regenerate. Embracing the new ecology, Pearce shows us, is our best chance. To be an environmentalist in the twenty-first century means celebrating nature’s wildness and capacity for change.

It is well-illustrated, provides summaries of the most important invasive species and issues impacting all regions of the country, and includes a comprehensive primary reference list for each topic. This scientific synthesis provides the cultural, economic, scientific and social context for addressing environmental challenges posed by invasive species and will be a valuable resource for scholars, policy makers, natural resource managers and practitioners.
Download or read book Invasive Birds written by Colleen T. Downs and published by CABI. This book was released on 2020-12-07 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examining globally invasive alien birds, the first part of this book provides an account of 32 global avian invasive species (as listed by the Invasive Species Specialist Group, ISSG). It acts as a one stop reference volume; it assesses current invasive status for each bird species, including details of physical description, diet, introduction and invasion pathways, breeding behaviour, natural habitat. It also looks at the environmental impact of each species, as well as current and future control methods. Full colour photographs assist with species identification and global distribution maps give a visual representation of the current known distributions of these species. The second part of the book discusses the biogeographical aspects of avian invasions, highlighting current and emerging invasive species across different regions of the world. The third section considers the impact of invasive species on native communities, problems associated with invasive bird management and the use of citizen science in the study of invasive birds.
Download or read book Chance and Change written by William H. Drury and published by University of California Presson Demand. This book was released on 1998 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: The result of a lifetime in the field and in the classroom, Chance and Change challenges many of the tenets of establishment ecology. Charging that most of the environmental movement has ignored or rejected the changes in thinking that have infiltrated ecological theory since the mid 70s, William Drury presents a convincing case that disorder is what makes the natural world work, and that clinging to romantic notions of nature's grand design only saps the strength of the conservation movement. Drury's training in botany, geology, and zoology as well as his life-long devotion to work in the field gave him a depth and range of knowledge that few ecologists possess. This book opens our eyes to a new way of looking at the environment and forces us to think more deeply about nature and our role in it. Chance and Change is intended for the serious amateur naturalist or professional conservationist. Drury argues that chance and change are the rule, that the future is as unpredictable to other organisms as it is to us, and that natural disturbance is too frequent for equilibrium models to be useful. He stresses the centrality of natural selection in explaining the meaning of biology and insists the book and the laboratory must be checked at all times against the real world. Written in an easy, personal style, Drury's narrative comes alive with the landscape--the salt marshes, dunes, seashores, and forests--that he believed served as the best classroom. His novel approach of correlating landscape evolution with ecological principles offers a welcome corrective to discordance between what we observe in nature and what theory tells us we should see.

Download or read book Beyond the War on Invasive Species written by Tao Orion and published by Chelsea Green Publishing. This book was released on 2015-06-17 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive species are everywhere, from forests and prairies to mountaintops and river mouths. Their rampant nature and sheer numbers appear to overtake fragile native species and forever change the ecosystems that they depend on. Concerns that invasive species represent significant threats to global biodiversity and ecological integrity permeate conversations from schoolrooms to board rooms, and concerned citizens grapple with how to rapidly and efficiently manage their populations. These worries have culminated in an ongoing “war on invasive species,” where the arsenal is stocked with bulldozers, chainsaws, and herbicides put to the task of their immediate eradication. In Hawaii, mangrove trees (Avicennia spp.) are sprayed with glyphosate and left to decompose on the sandy shorelines where they grow, and in Washington, helicopters apply the herbicide Imazapyr to smooth cordgrass (Spartina alterniflora) growing in estuaries. The “war on invasive species” is in full swing, but given the scope of such potentially dangerous and ecologically degrading eradication practices, it is necessary to question the very nature of the battle. Beyond the War on Invasive Species offers a much-needed alternative perspective on invasive species and the best practices for their management based on a holistic, permaculture-inspired framework. Utilizing the latest research and thinking on the changing nature of ecological systems, Beyond the War on Invasive Species closely examines the factors that are largely missing from the common conceptions of invasive species, including how the colliding effects of climate change, habitat destruction, and changes in land use and management contribute to their proliferation. There is more to the story of invasive species than is commonly conceived, and Beyond the War on Invasive Species offers ways of understanding their presence and ecosystem effects in order to make more ecologically responsible choices in land restoration and biodiversity conservation that address the root of the invasion phenomenon. The choices we make on a daily basis—the ways we procure food, shelter, water, medicine, and transportation—are the major drivers of contemporary changes in ecosystem structure and function; therefore, deep and long-lasting ecological restoration outcomes will come not just from eliminating invasive species, but through conscientious redesign of these production systems.
Download or read book Invasion Biology written by Jonathan M Jeschke and published by CABI. This book was released on 2018-04-25 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many hypotheses describing the interactions involved in biological invasions, but it is largely unknown whether they are backed up by empirical evidence. This book fills that gap by developing a tool for assessing research hypotheses and applying it to twelve invasion hypotheses, using the hierarchy-of-hypotheses (HoH) approach, and mapping the connections between theory and evidence. In Part 1, an overview chapter of invasion biology is followed by an introduction to the HoH approach and short chapters by science theorists and philosophers who comment on the approach. Part 2 outlines the invasion hypotheses and their interrelationships. These include biotic resistance and island susceptibility hypotheses, disturbance hypothesis, invasional meltdown hypothesis, enemy release hypothesis, evolution of increased competitive ability and shifting defence hypotheses, tens rule, phenotypic plasticity hypothesis, Darwin's naturalization and limiting similarity hypotheses and the propagule pressure hypothesis. Part 3 provides a synthesis and suggests future directions for invasion research.
