Since time immemorial mankind has taken it upon himself to wage war against nature — against those species of birds and mammals which he believes conflict with his livelihood. This remarkable book is about that war of attrition against the native mammals and birds of England and Wales from the middle ages to the present day. There is widespread knowledge about the huge declines in popular species such as song birds, farmland birds, otters, and pine martens, however, there is less understanding about the deep-rooted causes of these losses, or about the complex relationship between mankind and these species. Roger Lovegrove has undertaken years of unique research: by searching through parish records of 'vermin' trapped, hunted, and killed over the generations, he has revealed an unprecedentedly accurate and detailed picture of the history of a nation's wildlife, and of the often devastating impact and extinction that we have forced on our ecology. Consisting of species-by-species accounts, accompanied by beautiful, specially-commissioned illustrations, this book outlines the history - and often the future too - of a wealth of wildlife species, from badgers, bears and beavers, to wolves, kingfishers, the golden eagle and the humble house sparrow. The geographical scope is British, but the subject will be of interest to conservationists around the world because of the unique historical material that will be included. The topic has enormous relevance today, as public concern about the environment rises, and controversies rage about hunting, wildlife management and reintroduction of ancient species.

Behaviour problems" in our schools occupy a considerable part of the education agenda and media attention. The major thrust of the literature has been on the provision of "new classroom management approaches". Too often these "packages" are inappropriate to the specific context of the school and its pupils. There are no "quick-fix" solutions. In this book, Slee proposes a critical re-examination of the school discipline issue. In doing so, he provides an overview of policy change; an examination of the major schools of thought on student discipline; a reconsideration of the context in which young people, teachers and schools now find themselves; and practical responses for addressing all levels of discipline policy making.
Universally recognised as by far the most authoritative work ever published on the subject, The Birds of Africa is a superb multi-contributor reference work, with encyclopaedic species texts, stunning paintings of all species and numerous subspecies, informative line drawings, detailed range maps, and extensive bibliographies. Each volume contains an Introduction that brings the reader up to date with the latest developments in African ornithology, including the evolution and biogeography of African birds. Diagnoses of the families and genera, often with superspecies maps, are followed by the comprehensive species accounts themselves. These include descriptions of range and status, field characters, voice, general habits, food, and breeding habits. Full bibliographies, acoustic references, and indexes complete this scholarly work of reference. This eighth and final volume covers the Malagasy region which comprises Madagascar and the various islands and archipelagos of the Indian Ocean including the Seychelles, the Comoros, Mauritius and Réunion. Every resident and migrant species is covered in full detail, comparable to other volumes in the series, and with a colour map for each species. Vagrants are treated in less detail. All species are illustrated on a beautiful series of 64 colour plates, with original artwork from John Gale and Brian Small. This is a major work of reference on the birds of the region and will remain the standard text for many years to come.
A groundbreaking argument on how endothermy--arguably the most important innovation in vertebrate evolution--developed in birds and mammals "Vividly narrated and illustrated. . . . Provocative and fascinating for specialists and lay readers alike."--Southeastern Naturalist This pioneering work investigates why endothermy, or "warm-bloodedness," evolved in birds and mammals, despite its enormous energetic costs. Arguing that single-cause hypotheses to explain the origins of endothermy have stalled research since the 1970s, Barry Gordon Lovegrove advances a novel conceptual framework that considers multiple potential causes and integrates data from the southern as well as the northern hemisphere. Drawing on paleontological data; research on extant species in places like the Karoo, Namaqualand, Madagascar, and Borneo; and novel physiological models, Lovegrove builds a compelling new explanation for the evolution of endothermy. Vividly narrated and illustrated, this book stages a groundbreaking argument that should prove provocative and fascinating for specialists and lay readers alike.
Since time immemorial mankind has taken it upon himself to wage war against nature -- against those species of birds and mammals which he believes conflict with his livelihood. This remarkable book documents the history of that battle in England and Wales from the Middle Ages, shedding a new light on the history of our much-loved wildlife.
A wide-ranging account of how birds spend the quiet half of their lives Birds at Rest is the first book to give a full picture of how birds rest, roost, and sleep, a vital part of their lives. It features new science that can measure what is happening in a bird’s brain over the course of a night or when it has flown to another hemisphere, as well as still-valuable observations by legendary naturalists such as John James Audubon, Alfred Russel Wallace, and Theodore Roosevelt. Much of what they saw and what ornithologists are studying today can be observed and enjoyed by any birder. From the poles to the tropics, how, when, and where birds sleep reflect the ecology and behavior of each species, as well as their evolution from dinosaur ancestors. Some sleep briefly, their brain half awake, others spend long cold nights in torpor, and a few can sleep while flying. Their roosting habits are also varied. Most birds sleep alone, some in pairs or families, while others in flocks of millions. Birds at Rest explains how each strategy works over the course of a season, a year, or a lifetime by providing protection, mating opportunities, information about food, and other survival benefits. With evocative drawings by artist and illustrator Margaret La Farge, Birds at Rest discusses how environmental challenges such as artificial lights and noise, invasive species, and climate change are disrupting avian sleep and proposes solutions to ensure that birds get the rest they need.
Shearwater is sheer delight, a luminous portrait of a magical seabird which spans the watery globe' Daily Mail. 'Charming and impassioned ... a rich tribute to an extraordinary bird.' Horatio Clare, author of A Single Swallow and Heavy Light. A very personal mix of memoir and natural history from the author of Liquid Gold. Ten weeks into its life, a Manx shearwater chick will emerge from its burrow and fly 8,000 miles from the west coast of the British Isles to the South Atlantic. It will be unlikely to touch land again for four years. Part memoir, part homage to wilderness, Shearwater traces the author's 50-year obsession with one of nature's supreme travellers. In the finest tradition of nature writing, Roger Morgan-Grenville, author of Liquid Gold - described by Mary Colwell ( Curlew Moon) as 'a book that ignites joy and warmth' - unpicks the science behind its incredible journey; and into the story of a year in the shearwater's life, he threads the inspirational influence of his Hebridean grandmother who instilled in him a love of wild places and wild animals. Full of lightly-worn knowledge, acute human observation and self-deprecating humour, Shearwater brings to life a truly mysterious and charismatic bird.
Mankind has reached deep space. Separated from earth and each other by unimaginable reaches of space, forced to adapt to various diverse planetary environments the colonies have become isolated and inward looking, forgetting their pasts, losing touch with their humanity. Until a mysterious ship found locked in the deep rock by a mining team on a planet whose surface is drenched in lethal radiation sparks off a deadly conspiracy that threatens man wherever he is. After his grim dystopias set on a failing earth Roger Levy has spread his wings to give us a broad and exciting SF novel of exotic locales and mindblowing ideas without losing any of his trademark psychological acuity and elegant style.
“Reveals the strange and wondrous adaptations birds rely on to get by.” —National Audubon Society When we see a bird flying from branch to branch happily chirping, it is easy to imagine they lead a simple life of freedom, flight, and feathers. What we don’t see is the arduous, life-threatening challenges they face at every moment. Beaks, Bones, and Bird Songs guides the reader through the myriad, and often almost miraculous, things that birds do every day to merely stay alive. Like the goldfinch, which manages extreme weather changes by doubling the density of its plumage in winter. Or urban birds, which navigate traffic through a keen understanding of posted speed limits. In engaging and accessible prose, Roger Lederer shares how and why birds use their sensory abilities to see ultraviolet, find food without seeing it, fly thousands of miles without stopping, change their songs in noisy cities, navigate by smell, and much more.
On a desert planet, two boys meet, sparking a friendship that will change human society forever. On the windswept world of Bleak, a string of murders lead a writer to a story with unbelievable ramifications. One man survives the vicious attacks, but is left with a morbid fascination with death; the perfect candidate for the perilous job of working on a rig. Welcome to the System. Here the concept of a god has been abandoned, and a new faith pervades: AfterLife, a social media platform that allows subscribers a chance at resurrection, based on the votes of other users. So many Lives, forever interlinked, and one structure at the centre of it all: the rig.
Pasquier describes the season's distinct conservation challenges for birds that winter where they have bred and for migrants to distant regions. Filled with elegant line drawings, the text describes how winter influences the lives of birds from the poles to the equator.
The African lion (Panthera leo), long celebrated as the king of beasts, faces unprecedented challenges in the wild today. Loss of habitat through the expansion of human activity increasingly restricts the lion to game reserves and national parks, while diseases such as bovine tuberculosis pose a threat to the health of lion prides. Over a period of two years, Roger and Pat de la Harpe have documented wild lions of South Africa, and the result is a superbly photographed and engagingly written tribute to this often misunderstood predator. In Search of the African Lion enters the complex world of the lion, describing pride dynamics, hunting patterns, the reproductive cycle and interactions with human communities. The book focuses on four main areas: the Kalahari, the Madikwe/Mapungubwe area, the Greater Kruger National Park and Northern Zululand -each with its own problems, challenges and opportunities. In addition, the authors highlight the important work done by game rangers, wildlife managers and scientific researchers in understanding the lion and in protecting existing populations. The In Search of... series focuses on the plight of threatened and endangered species. Also available by the same authors: In Search of the African Wild Dog.
The properties of rubbers are subject to change as a result of ageing, ultimately to the point where the material is no longer capable of fulfilling its function. After a brief introduction to the main environmental and mechanical factors affecting performance, this review focuses on the thermo-oxidative ageing of rubber. It considers the methods of, and the published results from, both natural and accelerated tests. A major section of the report is devoted to exposure and test techniques with discussion of the methods of physical and chemical analysis. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.
Rubber components are used in many demanding applications, from tyres and seals to gloves and medical devices, and failure can be catastrophic. This review of Rubber Product Failure outlines and illustrates the common causes of failure, while addressing ways of avoiding it. There has been increasing pressure to improve performance so that rubbers can be used at higher temperatures and in harsher environments. For example, the under-the-bonnet temperature has increased in some vehicles and new medical devices require longer lifetimes in potentially degrading biological fluids. The expectations of tyre performance in particular are increasing, and retreads have been in the spotlight for failures. The definition of failure depends on the application. For example, a racing car engine seal that lasts for one race may be acceptable, but in a normal car a life span of 10 years is more reasonable. If appearance is critical as in surface coatings and paints, then discolouration is failure, whilst in seals leakage is not acceptable. Each rubber product must be fit for the use specified by the consumer. Failure analysis is critical to product improvement. the cause of the problem can be much harder to find. It can range from a design fault to poor material selection, to processing problems, to manufacturing errors such as poor dimensional tolerances, to poor installation, product abuse and unexpected service conditions. The rubber technologist must become a detective, gathering evidence, understanding the material type and using deductive reasoning. Testing and analysis of failed materials and components add to the information available for failure analysis. For example, stored aged tyres appeared superficially to be alright for use, but on drum testing small cracks grew more quickly than in new tyres leading to rapid failure in service. Quality control procedures such as product inspection, testing and material quality checks can help to reach 100 percent reliability. In critical applications such as electricians' gloves for high voltage working, gloves are inspected before each use, while engine seals may be routinely replaced before the expected lifetime to avoid problems. in the literature is not high. However, several reviews have been written on specific products and references can be found at the end of this review. Around 400 abstracts from papers in the Polymer Library are included with an index. Subjects covered include tyre wear and failure, seals, engine components, rubber bonding failure, rubber failure due to chloramine in water, tank treads, gloves and condoms, medical devices and EPDM roofing membranes.
Polymers have been used in agriculture and horticulture since the middle of the last century. There is a tremendous potential for using polymers in agriculture and our fields and garden would look very different if we did not use polymers in them. This review traces the history of polymer use, discusses the markets for polymers in these applications, and describes in detail the different types of polymers that can be used and their specific applications. An additional indexed section containing several hundred abstracts from the Polymer Library gives useful references for further reading.

This volume sets out for the first time the historical and current status of all the bird species found in Wales together with their present distribution. The rugged countryside of Wales has long been a destination for successive generations of naturalists, ornithologists, oologists and, latterly, birdwatchers. Since the pioneering days of Willoughby and Ray, Pennant and Edward Llwyd, a growing number of intrepid travellers have recorded the wildlife and other natural riches of the mountains and coastlines of Wales. Despite these beginnings and the more recent twentieth century vogue for birdwatching, no volume on the birds of Wales has been produced until now to serve the increasing need for scientifically valid information for conservation purposes. In the years that have passed since the first naturalists visited Wales, changes of unimaginable scale have taken place in the Welsh countryside which have had equally dramatic impacts on the native bird communities. A succession of bird species have either been eliminated deliberately by the hand of man - mainly birds of prey - or have been dispossessed by changes in land use, the spread of industrialisation, urbanisation and pollution, trends which continue today to the increasing detriment of even some of our most familiar countryside birds. Much fine habitat remains however, and new species have come in to colonise Wales and add to the magic of its countryside. The three authors, all staff of the RSPB in Wales, have between them an accumulated experience of some 80 years of first-hand knowledge of birds in the Principality. Their knowledge and love of the birds and Wales itself makes this authoritative volume a landmark both in Welsh and ornithological publishing.
