Orcas Everywhere: The History and Mystery of Killer Whales (Orca Wild #1)

by Mark Leiren-Young

Orcas are found in every ocean on the planet. But can they survive their relationship with humans? Orcas Everywhere looks at how humans around the world (Indigenous and non-Indigenous alike) related to orcas in the past, how we relate to them now and what we can do to keep cetacean communities alive and thriving. The book deals with science, philosophy, environmentalism and ethics in a kid-friendly and accessible way. Writer, filmmaker and orca activist Mark Leiren-Young takes us back to when killer whales were considered monsters and examines how humans went from using orcas for target practice to nearly loving them to death. If you know a young person who loves Free Willy or Finding Nemo, they will fall in love with these whales.

The Orchid Outlaw: On a Mission to Save Britain's Rarest Flowers

by Ben Jacob

The fascinating story of one man's mission to track down and rescue rare orchids from destruction on the building sites of Britain.Ben Jacob is an orchid thief. He spends his life (and risks prison) tracking down rare orchids and rescuing them from unwitting destruction on the building sites and greenbelt developments of Britain. This is his story.Ben fell in love with orchids as a nine-year-old, when his parents bought him a Cymbidium. That love then led him to spend his twenties in various tropical cities, teaching English and exploring jungles where exotic orchid species grew wild, pollinated by hummingbirds, huge moths and more. After a decade abroad, Ben returned to the UK. Here, his passion re-ignited when he encountered a colony of Bee orchids, a cryptic species which tricks bees into mating with its flowers. Ben was entranced. Having long seen Britain's orchids as pale imitations of their tropical cousins, he changed his mind completely and set out to find and photograph all fifty-one British species.Reading and learning everything he could, Ben realised that Britain's orchids are in desperate trouble. Some, such as Summer's Lady Tresses, have gone extinct; others, such as the magnificently strange Ghost Orchid, have not been seen since 2009; all have experienced vertiginous declines. Changes in land use and climate are responsible, but so too are Britain's outdated environmental and planning laws, which seem incapable of protecting rare species in the face of the drive to build new homes and infrastructure.That's how Ben turned outlaw. He began saving orchids slated for destruction, digging them out in the middle of the night and replanting them in safe places, all this while knowing that the work he was doing was illegal, for if arrested Ben could have been fined £5,000 for each wild orchid plant he saved, and he might even have faced prison.Part memoir, part fascinating history of our most exotic and yet overlooked flower, this is nature writing with a real story. Ben shares with us his mission, and raises urgent questions about our environmental legislation.The world needs more Bens.(P) 2023 Hodder & Stoughton Limited

The Orchid Outlaw: On a Mission to Save Britain's Rarest Flowers

by Ben Jacob

TEN YEARS AGO, BEN JACOB TURNED OUTLAW TO SAVE OUR RAREST FLOWERS. THIS IS HIS STORY.Obsessed by orchids since childhood, Ben spent years travelling to far-flung jungles to see them in the wild. Then a chance encounter set him off on a journey of discovery into the wonderful, but often forgotten, world of Britain's fifty-one native species. These include the Bee which looks (and smells) so much like one that even bees are fooled, the Ghost which exists without sunlight, and Autumn Lady's Tresses which gave Darwin the proof he needed for his theory of evolution.But our orchids are in desperate trouble. Many species are facing extinction. Decimated by changes in land use and climate, inadequately protected by environmental and planning laws, their habitats are disappearing fast. Determined to act before it was too late, Ben broke into building sites in the dead of night to rescue threatened plants, and turned his kitchen into a laboratory, his fridge into storage for hundreds of baby orchids, and his back yard into a plantation. But doing all that put him on the wrong side of the law. . . At once a memoir, a natural history, and an inspiring call to action, reintroducing us to Britain's most endangered flowers, The Orchid Outlaw shows us how we can all save the world, one plant at a time.

Order and Fluctuations in Collective Dynamics of Swimming Bacteria: Experimental Exploration of Active Matter Physics (Springer Theses)

by Daiki Nishiguchi

This thesis focuses on experimental studies on collective motion using swimming bacteria as model active-matter systems. It offers comprehensive reviews of state-of-the-art theories and experiments on collective motion from the viewpoint of nonequilibrium statistical physics. The author presents his experimental studies on two major classes of collective motion that had been well studied theoretically. Firstly, swimming filamentous bacteria in a thin fluid layer are shown to exhibit true, long-range orientational order and anomalously strong giant density fluctuations, which are considered universal and landmark signatures of collective motion by many numerical and theoretical works but have never been observed in real systems. Secondly, chaotic bacterial turbulence in a three-dimensional dense suspension without any long-range order as described in the first half is demonstrated to be capable of achieving antiferromagnetic vortex order by imposing a small number of constraints with appropriate periodicity. The experimental results presented significantly advance our fundamental understanding of order and fluctuations in collective motion of motile elements and their future applications.

Ordinary Cities: Between Modernity and Development (Questioning Cities)

by Jennifer Robinson

With the urbanization of the world's population proceeding apace and the equally rapid urbanization of poverty, urban theory has an urgent challenge to meet if it is to remain relevant to the majority of cities and their populations, many of which are outside the West. This groundbreaking book establishes a new framework for urban development. It makes the argument that all cities are best understood as ‘ordinary’, and crosses the longstanding divide in urban scholarship and urban policy between Western and other cities (especially those labelled ‘Third World’). It considers the two framing axes of urban modernity and development, and argues that if cities are to be imagined in equitable and creative ways, urban theory must overcome these axes with their Western bias and that resources must become at least as cosmopolitan as cities themselves. Tracking paths across previously separate literatures and debates, this innovative book - a postcolonial critique of urban studies - traces the outlines of a cosmopolitan approach to cities, drawing on evidence from Rio, Johannesburg, Lusaka and Kuala Lumpur. Key urban scholars and debates, from Simmel, Benjamin and the Chicago School to Global and World Cities theories are explored, together with anthropological and developmentalist accounts of poorer cities. Offering an alternative approach, Ordinary Cities skilfully brings together theories of urban development for students and researchers of urban studies, geography and development.

Ordinary Differential Equations with Applications (Texts in Applied Mathematics #34)

by Carmen Chicone

This book, developed during 20 years of the author teaching differential equations courses at his home university, is designed to serve as a text for a graduate level course focused on the central theory of the subject with attention paid to applications and connections to other advanced topics in mathematics. Core theory includes local existence and uniqueness, the phase plane, Poincaré-Bendixson theory, Lyapunov and linearized stability, linear systems, Floquet theory, the Grobman–Hartman theorem, persistence of rest points and periodic orbits, the stable and center manifold theorems, and bifurcation theory. This edition includes expanded treatment of deterministic chaos, perturbation theory for periodic solutions, boundary value problems, optimization, and a wide range of their applications. In addition, it contains a formulation and new proof of a theorem on instability of rest points in the presence of an eigenvalue with positive real part, and new proofs of differential inequalities and Lyapunov’s center theorem. New sections present discussions of global bifurcation, the Crandall–Rabinowitz theorem, and Alekseev’s formula. Of particular note is a new chapter on basic control theory, a discussion of optimal control, and a proof of a useful special case of the maximum principle. A key feature of earlier editions, a wide selection of original exercises, is respected in this edition with the inclusion of a wealth of new exercises. Reviews of the first edition:“As an applied mathematics text on linear and nonlinear equations, the book by Chicone is written with stimulating enthusiasm. It will certainly appeal to many students and researchers.”—F. Verhulst, SIAM Review “The author writes lucidly and in an engaging conversational style. His book is wide-ranging in its subject matter, thorough in its presentation, and written at a generally high level of generality, detail, and rigor.”—D. S. Shafer, Mathematical Reviews

Oregon City Floods (Images of America)

by Clackamas County Historical Society

Native American legends from times long ago tell of great floods that covered the earth in the Pacific Northwest. Early fur trappers describe the Willamette River as a sheet of water covering the land as far as the eye can see in the early 1800s. As American settlement of the Oregon Territory began in the 1840s, a great flood carried away many of the new businesses at the base of majestic Willamette Falls. Again and again the rivers rose, inundating the historic city to the north and south. But Oregon City, the first incorporated city in the Oregon Territory, survives, thrives, and grows despite these floods.

Ores to Metals

by James Fell

This comprehensive treatment of the smelting industry of Colorado, originally published in 1979, is now back in print with a new preface by the author. Packed with fascinating statistics and mining data, Ores to Metals details the people, technologies, and business decisions that have shaped the smelting industry in the Rockies. Although mining holds more of the glamour for those in and interested in the minerals industry, smelters have continuously played a critical role in the industry's evolution since their introduction in Colorado in the 1860s. At that time, miners desperately needed new technology to recover gold and silver from ores resistant to milling. Beginning as small independent enterprises, progressing to larger integrated firms working in urban centers, and finally following a trend toward mergers, the entire industry was absorbed into one large holding company - the American Smelting and Refining Company. Over time, fortunes were won and lost, business success was converted to political success, and advances were made in science and metallurgy. Drawing on archival material, Fell expertly presents the triumphs and troubles of the entrepreneurs who built one of the great industries of the West.

Organic Agriculture and Climate Change

by Klaus Lorenz Rattan Lal

This book will collate, review and synthesize information on how Organic Agriculture (OA) practices affect and are affected by climate change, in comparison to the more widely used conventional agricultural practices. Pros and cons of OA practices will be discussed separately for croplands, pasture lands, mixed livestock cropping systems, vegetable fields, fruit and tree orchards, and vineyards. The book concludes with an overview on how conventional and OA practices can be prudently and discriminately combined to identify and adopt climate-resilient agro-ecosystems under site-specific conditions.

The Organic Farmer's Business Handbook

by Richard Wiswall

Contrary to popular belief, a good living can be made on an organic farm. What's required is farming smarter, not harder. InThe Organic Farmer's Business Handbook, Richard Wiswall shares advice on how to make your vegetable production more efficient, better manage your employees and finances, and turn a profit. From his twenty-seven years of experience at Cate Farm in Vermont, Wiswall knows firsthand the joys of starting and operating an organic farm-as well as the challenges of making a living from one. Farming offers fundamental satisfaction from producing food, working outdoors, being one's own boss, and working intimately with nature. But, unfortunately, many farmers avoid learning about the business end of farming; because of this, they often work harder than they need to, or quit farming altogether because of frustrating-and often avoidable-losses. In this comprehensive business kit, Wiswall covers: Step-by-step procedures to make your crop production more efficient Advice on managing employees, farm operations, and office systems Novel marketing strategies What to do with your profits: business spending, investing, and planning for retirement A companion CD offers valuable business tools, including easy-to-use spreadsheets for projecting cash flow, a payroll calculator, comprehensive crop budgets for twenty-four different crops, and tax planners.

Organic Farming, Pest Control and Remediation of Soil Pollutants

by Eric Lichtfouse

Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur from the molecular level to the farming system to the global level at time scales ranging from seconds to centuries. For that, scientists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable agriculture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. Because most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world. This book series gathers review articles that analyze current agricultural issues and knowledge, then propose alternative solutions. It will therefore help all scientists, decision-makers, professors, farmers and politicians who wish to build a safe agriculture, energy and food system for future generations.

Organic Futures: Struggling for Sustainability on the Small Farm

by Brian Gareau Connor J. Fitzmaurice

An exploration of the lived experience of small-scale organic farmers in New England that unpacks how they balance their ideals with economic realities In recent years, the popularity of organically grown produce has exploded. In 2014, organic fruits and vegetables accounted for 12% of all produce sales in the United States, with $39 billion in consumer sales reported for 2015. As a federally recognized niche market within the agricultural mainstream, organic farming is increasingly on display in American grocery stores. Yet the organic food most Americans consume today is produced by an industrial food system at odds with the practices and ideals of small-scale farmers. Taking an ethnographic approach, the fieldwork by Connor Fitzmaurice and Brian Gareau at a small New England organic farm sheds light on how farmers navigate the difficult terrain between practices of sustainability and the economic realities of contemporary agriculture. Drawing on extensive research, Fitzmaurice and Gareau examine the historical context, complexities, and viability of nonconventional organic farming practices: practices that seek to balance ecology and community with the business of agriculture.
