North American Crop Wild Relatives, Volume 1: Conservation Strategies

The plant species that humans rely upon have an extended family of wild counterparts that are an important source of genetic diversity used to breed productive crops. These wild and weedy cousins are valuable as a resource for adapting our food, forage, industrial and other crops to climate change. Many wild plant species are also directly used, especially for revegetation, and as medicinal and ornamental plants. North America is rich in these wild plant genetic resources. This book is a valuable reference that describes the important crop wild relatives and wild utilized species found in Canada, the United States and Mexico. The book highlights efforts taken by these countries to conserve and use wild resources and provides essential information on best practices for collecting and conserving them. Numerous maps using up-to-date information and methods illustrate the distribution of important species, and supplement detailed description on the potential value these resources have to agriculture, as well as their conservation statuses and needs. There is broad recognition of the urgent need to conserve plant diversity; however, a small fraction of wild species is distinguished by their potential to support agricultural production. Many of these species are common, even weedy, and are easily overshadowed by rare or endangered plants. Nevertheless, because of their genetic proximity to agriculturally important crops or direct use, they deserve to be recognized, celebrated, conserved, and made available to support food and agricultural security. This comprehensive two-volume reference will be valuable for students and scientists interested in economic botany, and for practitioners at all levels tasked with conserving plant biodiversity.The chapters 'Public Education and Outreach Opportunities for Crop Wild Relatives in North America' and 'Genetic Resources of Crop Wild Relatives – A Canadian Perspective' are open access under a CC BY 4.0 license via link.springer.com.

North American and European Perspectives on Sustainability in Higher Education (World Sustainability Series)

The scientific, cultural and diplomatic relations between Europe and its partners in North America are very strong. From a scientific point of view, this long-standing cooperation has taken place across a wide range of areas. They include the field of sustainability, where North America and Europe are working hand in hand, seeking solutions to the many regional and global problems currently faced. Against this backdrop and in order to facilitate a broad discussion on the contribution of higher education institutions from both sides of the Atlantic towards a more sustainable future, this book is being produced. The book gathers inputs from universities and research organizations on the one hand, but also from companies and enterprises on the other, from Europe and North America, working on matters related to sustainable development in a higher education context. It also provides a platform for the dissemination of information on the latest initiatives, paving the way for technology transfer and networking. Furthermore, the book intends to provide a fertile basis upon which European and North American organizations may cooperate more closely in this key area. Last but not least, a further aim of the book is to present methodological approaches and experiences deriving from case studies and projects, which aim to show how sustainability in North America and in Europe may be enhanced in practice.

North Atlantic Right Whales: From Hunted Leviathan to Conservation Icon

The fascinating story of North Atlantic right whales—from their evolutionary origin, through a thousand-year history of relentless pursuit by whalers, to ongoing efforts to rescue them from the brink of extinction.In the cold waters of the unforgiving North Atlantic Ocean, some of the heartiest humans of medieval days ventured out in search of whales. Through the centuries, people on both sides of the Atlantic became increasingly dependent on whale oil and other cetacean products. To meet this growing demand, whaling became ever more sophisticated and intense, leading to the collapse of what was once a seemingly inexhaustible supply of large cetaceans. Central to the whale's subsequent struggle for existence has been one species—the North Atlantic right whale. Conservationist David W. Laist now provides the first complete history of the North Atlantic right whale, from its earliest encounters with humans to its close brush with extinction, to its currently precarious yet hopeful status as a conservation icon.Favored by whalers because of their high yields of oil and superior baleen, these giants became known as "the right whale to hunt," and their numbers dwindled to a mere 100 individuals worldwide. Their dire status encouraged the adoption of a ban on hunting and a treaty that formed the International Whaling Commission. Recovery of the species, however, has proven elusive. Ship strikes and entanglement in commercial fishing gear have hampered herculean efforts to restore the population. Today, only about 500 right whales live along the US and Canadian Atlantic coasts—an improvement from the early twentieth century, but still a far cry from the thousands that once graced Atlantic waters.Laist's masterpiece features an incredible collection of photographs and artwork that give life to the fascinating history that unfolds in its pages. The result is a single volume that offers a comprehensive understanding of North Atlantic right whales, the role they played in the many cultures that hunted them, and our modern attempts to help them recover.

North Pacific Fisheries Management (Routledge Revivals)

In anticipation of the UN Conference of the Law of the Sea taking place in 1973, Dr Kasahara and Dr Burke of the University of Washington first published North Pacific Fisheries Management earlier that year. The conference brought fishery territories to a global stage with delegates that may not be as informed about ocean issues as those previously making decisions. Therefore the Program of International Studies of Fishery Arrangements was created to explore the management of fisheries in specific regions. This study focusses on the North Pacific region and delves into the implications of a global regime, generic problems concerning fishery management, distribution and institutions as well as alternative arrangements that can be made to make the management of fisheries smoother. This title will be of interest to students of environmental studies and policy makers.

North Pole, South Pole: The Epic Quest to Solve the Great Mystery of Earth's Magnetism

This &“fantastic story&” of one of physics&’ great riddles takes us through centuries of scientific history (Simon Lamb, author of Devil in the Mountain). Why do compass needles point north—but not quite north? What guides the migration of birds, whales, and fish across the world&’s oceans? How is Earth able to sustain life under an onslaught of solar wind and cosmic radiation? For centuries, the world&’s great scientists have grappled with these questions, all rooted in the same phenomenon: Earth&’s magnetism. Over two thousand years after the invention of the compass, Einstein called the source of Earth&’s magnetic field one of greatest unsolved mysteries of physics. Here, for the first time, is the complete history of the quest to understand the planet&’s attractive pull—from the ancient Greeks&’ fascination with lodestone to the geological discovery that the North Pole has not always been in the North—and to the astonishing modern conclusions that finally revealed the true source. Richly illustrated and skillfully told, North Pole, South Pole unfolds the human story behind the science: that of the inquisitive, persevering, and often dissenting thinkers who unlocked the secrets at our planet&’s core. &“In recent years, many very good books for interested non-scientists have been published: Richard Dawkins&’s Climbing Mount Improbable and The Ancestor&’s Tale, Stephen Jay Gould&’s The Lying Stones of Marrakech, and Dava Sobel&’s Longitude and The Planets, to name some of them. North Pole, South Pole . . . is a worthy addition to that list . . . Turner has a great story to tell, and she tells it well.&” —The Press (New Zealand)

North on the Wing: Travels with the Songbird Migration of Spring

The story of an ornithologist's journey to trace the spring migration of songbirds from the southern border of the United States through the heartland and into Canada.In late March 2015, ornithologist Bruce M. Beehler set off on a solo four-month trek to track songbird migration and the northward progress of spring through America. Traveling via car, canoe, and bike and on foot, Beehler followed woodland warblers and other Neotropical songbird species from the southern border of Texas, where the birds first arrive after their winter sojourns in South America and the Caribbean, northward through the Mississippi drainage to its headwaters in Minnesota and onward to their nesting grounds in the north woods of Ontario. In North on the Wing, Beehler describes both the epic migration of songbirds across the country and the gradual dawning of springtime through the U.S. heartland--the blossoming of wildflowers, the chorusing of frogs, the leafing out of forest canopies--and also tells the stories of the people and institutions dedicated to studying and conserving the critical habitats and processes of spring songbird migration. Inspired in part by Edwin Way Teale's landmark 1951 book North with the Spring, this book--part travelogue, part field journal, and part environmental and cultural history--is a fascinating first-hand account of a once-in-a-lifetime journey. It engages readers in the wonders of spring migration and serves as a call for the need to conserve, restore, and expand bird habitats to preserve them for future generations of both birds and humans.

North to the Future: An Offline Adventure through the Changing Wilds of Alaska

Hailed as a &“worthy successor&” to John McPhee (Kirkus Reviews), Ben Weissenbach —a digital native with little prior wilderness experience—embarks on a series of scientific adventures across the wilds of Alaska with some of the state's most distinguished and audacious researchers. At the age of twenty, college student Ben Weissenbach went north to Arctic Alaska armed with little more than inspiration from his literary heroes and a growing interest in climate change. What met him there was a world utterly unlike the 21st century Los Angeles in which he grew up—a land of ice, rock, and grizzlies seen by few outside a small contingent of scientists with big personalities. There&’s Roman Dial, the larger-than-life ecologist with whom Ben walks and rafts a thousand miles across Alaska&’s Brooks Range. There&’s Kenji Yoshikawa, the reindeer-herding permafrost expert who leaves Ben alone for eleven days to care for his off-grid homestead, where temperatures drop to -49 degrees Fahrenheit. And there&’s Matt Nolan, the independent glaciologist who flies him to the largest glaciers in the American Arctic. As these scientists teach Ben to read Alaska's warming landscape, he confronts the limits of digital life and the complexity of the world beyond his screens. He emerges from each adventure with a new perspective on our modern relationship to technology and a growing wonder for our fast-changing—ever-changing—natural world.

North-South Grain Markets And Trade Policies

The book is composed of a series of case studies. The countries included reflect the interest and experience of the authors who collaborated in preparing the volume. No attempt was made to provide representative coverage based upon a comprehensive classiftcation of countries, which is why there are no chapters dealing with such exporters as Argentina or Thailand or importers such as Egypt or Japan. Despite the somewhat eclectic geographical mix, many of the fundamental issues that face the North and the South, both individually and collectively, are illustrated by the case countries. We would argue that there is much to be learned about the effective implementation of policy choices and the constraints that policymakers face by looking at individual country experiences, rather than by attempting to generalize on the basis of an abstract theoretical framework There is a dearth of information on what countries actually do in managing domestic grain markets.

Northern Forested Wetlands Ecology and Management

Forested wetlands are a major component of northern landscapes, important both for their ecological functions and their socioeconomic values. Historically, these lands have been used for timber and fiber products, hunting, fishing, trapping, food gathering, and recreation. There are many questions about the use and management of these lands in the future, particularly with respect to forest products, hydrology and water quality, plant and wildlife ecology, landscape dynamics, and wetland restoration. Northern Forested Wetlands: Ecology and Management provides a synthesis of current research and literature. It examines the status, distribution, and use of these wetland resources. The book focuses on understanding the role of wetlands in the landscape and on how to manage these wetlands and sustain their important functions. This is a primary reference text for the study and management of northern forested wetlands, providing a forum for information discovered by researchers and managers from many nations.

Northern Pike: Ecology, Conservation, and Management History

The northern pike—sometimes affectionately known as the &“aquatic wolf&”—is one of the most sought after and mythologized fishes in Minnesota, but until now there have been few books devoted to the history and ecological management of the species. Based on pioneering research carried out in Minnesota by leading pike specialist Rodney B. Pierce, Northern Pike Ecology, Conservation, and Management History is the most complete collection of information to date on the species, for everyone from scientists and conservation biologists to general readers and recreational anglers.A tremendously important game fish and resource both in Minnesota and throughout the northern hemisphere, northern pike populations directly reflect local geology and human influence, playing a key role in the health of freshwater ecosystems. As urbanization spreads and the human population continues to grow, pike populations face increasing pressure, requiring new ways of looking at and managing the species. In Minnesota, groundbreaking work has been conducted on northern pike: analyses of stocking success and investigations into the relationships within fish communities, the management of rearing marshes, environmental effects on natural production, the genetics of northern pike, and strategies for scientifically monitoring pike. The state has been a leader in developing fishing regulations to help restore large pike, among many other measures designed to ensure the future quantity and health of a key species in Minnesota&’s waterways.Weaving significant historical scientific literature and technical details together with his own research, Pierce&’s benchmark study documents and synthesizes the long history of northern pike management and describes the latest efforts being taken to better understand and manage this critical and renowned species.

Northern Star: J.S. Plaskett

John Stanley Plaskett was Canada’s pre-eminent astronomer in the first half of the twentieth century. His legacy lives on in the observatory he founded in Victoria, British Columbia, and the reputation he built for Canada as a nation making vital contributions to basic science. Plaskett’s pioneering work with the most massive stars and his definitive determination of the rotation of the Milky Way Galaxy earned him international recognition of the highest order. Northern Star explores Plaskett’s unorthodox and fascinating life from his rural roots near Woodstock, Ontario through his days as a technician at the University of Toronto to his initiation in astronomy at the Dominion Observatory in Ottawa. His greatest achievements followed after he persuaded the government of Canada, in spite of the strictures of the First World War, to finance what was then the world’s largest operational telescope. Peter Broughton’s accessible and engaging prose illuminates Plaskett’s numerous achievements and the social, political, economic, and religious milieu surrounding them. This richly illustrated volume invites readers to understand the pull that Plaskett’s passions, personality, and motivations exerted on him during his lifetime.

Nose Dive: A Field Guide to the World's Smells

The ultimate guide to the smells of the universe--the ambrosial to the pungent, and everything in between--from the author of the acclaimed culinary guides On Food and Cooking and Keys to Good Cooking.From Harold McGee, James Beard Award-winning author and leading expert on the science of food and cooking, comes an extensive exploration of the awe-inspiring world of smell. In Nose Dive, McGee takes us on a sensory-filled adventure, from the sulfurous nascent earth more than four billion years ago, to the sweetly fragrant Tian Shan mountain range north of the Himalayas, to the keyboard of your laptop, where trace notes of formaldehyde escape between the keys. We'll sniff the ordinary (wet pavement and cut grass) and extraordinary (fresh bread and chocolate), the delightful (roses and vanilla) and the unpleasant (spoiled meat and rotten eggs). We'll smell each other. We'll smell ourselves.Through it all, McGee familiarizes us with the actual bits of matter that we breathe in -- the molecules that trigger our perceptions, that prompt the citrusy smells of coriander and beer and the medicinal smells of daffodils and sea urchins. And like everything in the physical world, molecules have histories. Many of the molecules that we smell every day existed long before any creature was around to smell them -- before there was even a planet for those creatures to live on. Beginning with the origins of those molecules in interstellar space, McGee moves onward through the smells of our planet, the air and the oceans, the forest and the meadows and the city, all the way to the smells of incense, perfume, wine, and food. Here is a story of the world, of all of the smells under our collective nose. A work of astounding scholarship and originality, Nose Dive distills the science behind the smells and translates it, as only McGee can, into an accessible and entertaining guide. Incorporating the latest insights of biology and chemistry, and interwoven with personal observations, McGee reveals how our sense of smell has the power to expose invisible, intangible details of our material world and life, and trigger in us feelings that are the very essence of being alive.
