E. GWINNER! The phenomenon of bird migration with its large scale dimensions has attracted the attention of naturalists for centuries. Worldwide billions of birds leave their breeding grounds every autumn to migrate to areas with seasonally more favor able conditions. Many of these migrants travel only over a few hundred kilo meters but others cover distances equivalent to the circumference of the earth. Among these long-distance migrants are several billion birds that invade Africa every autumn from their West and Central Palaearctic breeding areas. In the Americas and in Asia the scope of bird migration is of a similar magnitude. Just as impressive as the numbers of birds are their achievements. They have to cope with the enormous energetic costs of long-distance flying. particularly while crossing oceans and deserts that do not allow replenishment of depleted fat reserves. They have to appropriately time the onset and end of migrations. both on a daily and annual basis. And finally. they have to orient their migratory movements in space to reach their species- or population-specific wintering and breeding grounds, irrespective of the variable climatic conditions along their migratory routes.

This Book of Abstracts is the main publication of the 55th Annual Meeting of the European Association for Animal Production (EAAP) held in Bled, Slovenia, on 5-9 September 2004. It contains abstracts of the invited papers and contributed presentations. The meeting addressed subjects relating to science and innovation, but in Bled the main theme is "Sustainability of Livestock Systems". Also, important problems were discussed during the sessions of EAAP's nine Commissions: Animal Genetics, Animal Nutrition, Animal Management and Health, Animal Physiology, Livestock Farming Systems, Cattle Production, Sheep and Goat Production, Pig Production and Horse Production. In addition joint sessions on topics interesting several disciplines and species were included in the programme. A total of 2843 authors (741 abstracts) contributed to this publication.

Coastal Waders and Wildfowl in Winter

This 1984 book arose from an international meeting held at Texel in the Netherlands in April 1981 to discuss the feeding requirements and behaviour of shorebirds and coastal wildfowl. The book was designed both for general ornithologists, so that they may advise planners concerned with coastal wetlands, and for research workers interested in bird ecology and behaviour. The book is divided into three sections, each the responsibility of one of the editors, who provides a brief section introduction. The first covers bird numbers in relation to food resources; the second relates population densities to social and individual behaviour of birds within the flocks, and the third examines the role of areas of particular significance to migrant shorebirds along the route from West Africa to the high-latitude breeding grounds stretching from Greenland to western Siberia. This volume was produced in conjunction with the British Ornithologists' Union.

The Three Hostages

This early (1924) spy adventure is one of five Buchan novels featuring the heroic Richard Hannay. Hannay is called out of retirement to rescue the kidnapped offspring of three highly placed British citizens. Hannay soon uncovers a global syndicate supporting a single man who has notions of world domination. The story suffers from exaggerated descriptions of its characters. For instance, the kidnapper, Medina, is not just a good shot, he's the best shot in England next to the King. The British are portrayed as wonderful people, but other races fare less well. Yet the story is undoubtedly good fun and is enhanced by the modulated voice and subtle characterizations of British actor Edmund Dehn. For large suspense collections.

Conquering the Highlands

A history of the afforestation of the Scottish uplands

Deforestation of Scotland began millennia ago and by the early 20th century woodland cover was down to about 6 per cent of the total land area. A century later woodland cover had tripled. Most of the newly established forestry plantations were created on elevated land with wet peaty soils and high wind exposure, not exactly the condition in which forests naturally thrive. Jan Oosthoek tells in this book the story of how 20th century foresters devised ways to successfully reforest the poor Scottish uplands, land that was regarded as unplantable, to fulfil the mandate they had received from the Government and wider society to create a timber reserve. He raises the question whether the adopted forestry practice was the only viable means to create forests in the Scottish Highlands by examining debates within the forestry community about the appearance of the forests and their longterm ecological prospects. Finally, the book argues that the long held ecological convictions among foresters and pressure from environmentalists came together in the late 20th century to create more environmentally sensitive forestry.

Among birds, shorebirds provide some of the more unique opportunities to examine basic problems in behavior, ecology, and evolution. This is in large measure due to the diversity, both behaviorally and ecologically, of a group closely related taxonomically and distributed throughout the world. The overall aim of these two volumes is to provide a representative selection of current research being conducted on shorebird behavior and ecology. Traditionally, marine birds have included those species that breed in large colonies on offshore islands along coasts (see Volume 4 of this series). Although shorebirds have generally not been considered within this group, the fact that almost 40% of the species breed along coasts and more than 60% often or always spend the nonbreeding season in coastal habitats more than justifies their inclusion as marine birds (at least those species that totally or partially depend upon the marine environment). Their inclusion markedly increases species diversity in marine birds since shorebirds add about 217 species to the 280 that are traditionally thought of as marine.

A Scientist Audits the Earth

Humans use 50 percent of the world's freshwater supply and consume 42 percent of its plant growth. We are liquidating animals and plants one hundred times faster than the natural rate of extinction. Such numbers should make it clear that our impact on the planet has been, and continues to be, extreme and detrimental. Yet even after decades of awareness of our environmental peril, there remains passionate disagreement over what the problems are and how they should be remedied. Much of the impasse stems from the fact that the problems are difficult to quantify. How do we assess the impact of habitat loss on various species, when we haven't even counted them all? And just what factors go into that 42 percent of biomass we are hungrily consuming? It is only through an understanding of the numbers that we will be able to break that impasse and come to agreement on which environmental issues are most critical and how they might best be addressed. Working on the front lines of conservation biology, Stuart Pimm is one of the pioneers whose work has put the “science” in environmental science. In this book, he appoints himself “investment banker of the global, biological accounts,” checking the environmental statistics gathered by tireless scientists in work that is always painstaking and often heartbreaking. With wit, passion, and candor, he reveals the importance of understanding where these numbers come from and what they mean. To do so, he takes the reader on a globe-circling tour of our beautiful, but weary, planet from the volcanic mountains and rainforests of Hawai'i to the boreal forests of Siberia. At times, the view looks rather grim. Yet Pimm, ever the optimist, presents a world filled with mysterious beauty, the infinite variety of nature, and an urgent hope that through an understanding of our planet's environmental past and present, we will be inspired to save it from future extinction.
