The use of natural and seeded grass pastures for the feeding of livestock and other unfamiliar uses for the ubiquitous grass family are described in this succinct and beautifully illustrated work. This edition is exclusive to newnaturalists.com The New Naturalist series has already covered many facets of the interrelationship between man and nature, but the grass family is probably the most important man in the whole plant kingdom - just how important is shown in this book. Dr. Moore, the Principal of Seale Hayne Agricultural College in Devon, is our leading authority on grasses and their utilization. His special interest is the use of natural and seeded grass pastures for the feeding of livestock. Striking advances have been made in recent years in the improvement of such pastures and Dr. Moore deals very fully with this vital link in the feeding of the human race; but he also covers that other equally important role of the grass family in our economy, the cultivation of cereal crops for the production of grain. Grass lawns and playing fields form a centre-piece in most British gardens and public parks and there is a chapter on these, but the horticultural value of grasses as ornamental plants in herbaceous borders and woodland gardens is less well known. These and many other unfamiliar uses for the ubiquitous grass family are described in this succinct and beautifully illustrated work.

Pesticides and Pollution examines the problems of pollution of air, land, river, and the sea, by herbicides, pesticides, sewage, industrial effluents, gases, radiation, leakages, over-drainage, mistakes and mismanagement, in Britain today. From an objective and scientific standpoint, Dr. Mellanby examines the problems of pollution of air, land, river, and the sea, by herbicides, pesticides, sewage, industrial effluents, gases, radiation, leakages, over-drainage, mistakes and mismanagement, in Britain to-day. He sets out to placate neither farmers nor naturalists, but to explain in each case what is happening, to point to both dangers and practical necessities, and to discuss what steps should be taken. Dr. Mellanby is Director of the Nature Conservancy's Monks Wood Experimental Station, was head of the Entomology department at Rothamsted, and for many years before that did research in medical entomology both in Britain and the tropics.

Leslie Brown's account of our 15 resident, 7 vagrant and 2 migrant species of eagles, falcons, hawks and vultures in Britain presents a great mass of scientific information about our birds of prey in a manner as attractive to the general reader as to the dedicated ornithologist. The diurnal raptors are among the most arresting and dramatic of British bird species, from the magnificent and immense golden eagle of the Highlands to the more widespread but equally spectacular peregrine falcon and the frequent and adaptable kestrel of motorways and urban ledges. Leslie Brown's account of our 15 resident, 7 vagrant and 2 migrant species of eagles, falcons, hawks and vultures in Britain presents a great mass of scientific information about these birds in a manner as attractive to the general reader as to the dedicated ornithologist. Each of the resident species is discussed in detail - its status, past and present; its feeding and hunting behaviour; its life history; its breeding behaviour; migration and the threats to its survival. Then the biology of the birds of prey, changes in their habitat and status, their food habits, breeding behaviour, their territories and populations are examined in depth in separate chapters. An acknowledged world authority on birds of prey - co-author with Dean Amadon of Eagles, Hawks and Falcons of the World, and author of many other books besides - Leslie Brown is immensely enthusiastic; and the many tables, maps, figures and bibliography are all indicative of the thoroughness of his research. Also illustrated with 40 superb black and white photographs.

This is the first survey of the islands' natural history, complete in one volume. Because Orkney is exceptional, it is vital reading for the serious naturalist, as well as for being a comprehensive and absorbing guide for every visitor. This edition is exclusive to newnaturalists.com Orkney is a very special place for naturalists. Closer to Oslo than to London, its geography and climate create quite distinct environmental conditions - even though it is only six miles from the Scottish mainland. On these islands of fierce gales, long summer days and long winter nights, the wildlife has adapted in intriguing ways… Starlings adapt to ground-nesting…local sheep eat seaweed…and there are voles exclusive to Orkney. Here is one of the very few areas where the rare and delicate Scottish Primrose thrives…where you find the British stronghold of the Hen Harrier, and vast colonies of seabirds and seals. This is the first - and long-needed - survey of the islands' natural history, complete in one volume. Because Orkney is exceptional, it is vital reading for the serious naturalist, as well as for being a comprehensive and absorbing guide for every visitor. In his tracing of the island's evolution from its geological creation to the effects of oil technology; in the detailed, yet fascinating exploration of the plants and animals (and where best to see them), Professor Berry's expertise and enthusiasm is backed by that of local specialists, and Orkney's long tradition of natural history study. Appendices include definitive lists of all the species of flora and fauna on record, and an extensive bibliography.

Birds and bird lore provide a fascinating window onto our social and cultural history, and can tell us much about our changing relationship with the British landscape, our people and society. We Brits love our birds. They hold a special place in our hearts – whether it's the sound of birdsong on a spring morning, the sight of a Barn Owl hunting on a summer's evening, or a Robin perched on our garden spade. In this book, Stephen Moss focusses on some of our most beloved and charismatic birds. He explores their fascinating biology, and their place in the evolving culture and history of the British people. The author delves into the worlds of Sea Birds (Puffin, Sea Eagle and Gannet), Water Birds (Kingfisher, Swan and Avocet), Countryside Birds (Red Grouse, Nightingale and Skylark ) and Town & Garden Birds (Robin, House Sparrow and Magpie), weaving their stories together to tell four very different stories about the changing face of Britain.

This edition does not include illustrations. ‘Dry Store Room No. 1’ is an intimate biography of the Natural History Museum, celebrating the eccentric personalities who have peopled it and capturing the wonders of scientific endeavour, academic rigour and imagination. Behind the public fa?ade of any great museum there lies a secret domain: one of unseen galleries, locked doors, priceless specimens and hidden lives.Through the stories of the numerous eccentric individuals whose long careers have left their mark on the study of evolutionary science, Richard Fortey, former senior paleaontologist at London's Natural History Museum, celebrates the pioneering work of the Museum from its inception to the present day. He delves into the feuds, affairs, scandals and skulduggery that have punctuated its long history, and formed a backdrop to extraordinary scientific endeavour from Darwin to the present day. He explores the staying power and adaptability of the Museum as it responds to changes wrought by advances in technology and molecular biology – 'spare' bones from an extinct giant bird suddenly become cutting-edge science with the new knowledge that DNA can be extracted from them, and ancient fish are tested with the latest equipment that is able to measure rises in pollution. 'Dry Store Room No.1’ is a fascinating and affectionate account of a hidden world of untold treasures, where every fragment tells a story about time past, by a scientist who combines rigorous professional learning with a gift for prose that sparkles with wit and literary sensibility.

In one corner, a godless young warrior, Voltaire's heralded 'philosopher-king', the It Boy of the Enlightenment. In the other, a devout if bad-tempered old composer of 'outdated' music, a scorned genius in his last years. The sparks from their brief conflict illuminate a turbulent age. Behind the pomp and flash, Prussia's Frederick the Great was a tormented man, son of an abusive king who forced him to watch as his best friend (probably his lover) was beheaded. In what may have been one of history's crueler practical jokes, Frederick challenged 'old Bach' to a musical duel, asking him to improvise a six-part fugue based on an impossibly intricate theme (possibly devised for him by Bach's own son). Bach left the court fuming, but in a fever of composition, he used the coded, alchemical language of counterpoint to write 'A Musical Offering' in response. A stirring declaration of faith, it represented 'as stark a rebuke of his beliefs and world view as an absolute monarch has ever received,' Gaines writes. It is also one of the great works of art in the history of music. Set at the tipping point between the ancient and the modern world, the triumphant story of Bach's victory expands to take in the tumult of the eighteenth century: the legacy of the Reformation, wars and conquest, the birth of the Enlightenment. Brimming with originality and wit, 'Evening in the Palace of Reason' is history of the best kind - intimate in scale and broad in its vision.

The story of the 19th-century ice trade, in which ice from the lakes of New England – valued for its incredible purity – revolutionised domestic life around the world. In the days before artificial refrigeration, it was thought impossible to transport ice for long distances. But one man, Frederic Tudor, was convinced it could be done. This is the story of how, almost single-handedly, and in the face of near-universal mockery, he established a vast industry that would introduce the benefits of fresh ice to large parts of the globe. Thanks to Tudor, the American fashion for drinks ‘on the rocks’ spread to tropical areas such as the West Indies and British India. By the 1830s fleets of schooners carried the frozen cargo, packed with sawdust and tarpaulins for insulation, to all corners of the world. The harvesting of the ice from New England’s lakes employed thousands of men. The frozen water trade had a profound influence on the tastes of a large part of the world, but with the development of artificial cooling systems in the first quarter of the 20th century, the huge industry established by Frederic Tudor vanished as if it had never been. Note that it has not been possible to include the same picture content that appeared in the original print version.

The phenomenon of bird migration has fascinated people from time immemorial. The arrivals and departures of different species marked the seasons, heralding spring and autumn, and providing a reliable calendar long before anything better became available. Migration is shown by many kinds of animals, including butterflies and other insects, mammals, marine turtles and fish, but in none is it as extensively developed as in birds. The collective travel routes of birds span almost the entire globe, with some extreme return journeys covering more than 30,000 km. As a result of migration, bird distributions are continually changing – in regular seasonal patterns, and on local, regional or global scales. Migration has repeatedly prompted familiar questions, such as where birds go or come from, why do they do it, how do they know when and where to travel, and how do they find their way? In this book, Ian Newton sets out to answer these – and other – questions. The book is divided into four main sections: the first is introductory, describing the different types of bird movements, methods of study, and the main migration patterns seen around the British Isles; the second part is concerned mainly with the process of migration – with timing, energy needs, weather effects and navigation; the third with evolution and change in migratory behaviour; and the fourth with the geographical and ecological aspects of bird movements.
