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.

History and Climate Change

A Eurocentric Perspective

History and Climate Change is a balanced and comprehensive overview of the links between climate and man's advance from early to modern times. It draws upon demographic, economic, urban, religious and military perspectives. It is a synthesis of the many historical and scientific theories, which have arisen regarding man's progress through the ages. Central to the book is the question of whether climate variation is a fundamental trigger mechanism from which other historical sequences develop, or one amongst a number of other factors, decisive only when a regime/society is poised for change. Evidence for prolonged climate change is not that extensive. But it is clear that climatic variation has regularly played a part in historical development. Paricular attention is here paid to Europe since AD 211. Cold and warmth, wetness and aridity can create contrary reactions within societies, which can be interpreted in vary different ways by scholars from differenct disciplines. Does climate change exacerbate famine and epidemics? Did climate fluctuation play a part in pivotal historical events such as the mass exodus of Hsuing-nu from China, the pressure of the Huns on the Romans and the genesis of the Crusades? Did the bitter Finnish winter of 1939-40 ensure the ultimate defeat of Hitler? These episodes, and many others are discussed throughout the book in the authors distinctive style, with maps and photographs to illustrate the examples given.

Animals and the Shaping of Modern Medicine

One Health and its Histories

This book is open access under a CC BY 4.0 license. This book breaks new ground by situating animals and their diseases at the very heart of modern medicine. In demonstrating their historical significance as subjects and shapers of medicine, it offers important insights into past animal lives, and reveals that what we think of as ‘human’ medicine was in fact deeply zoological. Each chapter analyses an important episode in which animals changed and were changed by medicine. Ranging across the animal inhabitants of Britain’s zoos, sick sheep on Scottish farms, unproductive livestock in developing countries, and the tapeworms of California and Beirut, they illuminate the multi-species dimensions of modern medicine and its rich historical connections with biology, zoology, agriculture and veterinary medicine. The modern movement for One Health – whose history is also analyzed – is therefore revealed as just the latest attempt to improve health by working across species and disciplines. This book will appeal to historians of animals, science and medicine, to those involved in the promotion and practice of One Health today.

Arctic and Alpine Mycology II

During the summer of 1980, the First International symposium on Arctic and Alpine Mycology (ISAM-I) was held at the then extant Naval Arctic Research Laboratory near Barrow, Alaska, U.S.A., well within the Arctic Circle (Laursen and Ammirati, Arctic and Alpine Mycology. The First International symposium on Arcto-Alpine Mycology. Univ. Wash. Press, 1982). The facility is currently owned and operated by the Utkeagvik Inupiat community and is named the National Academic and Research Laboratory, thus retaining its acronym NARL. Twenty-five scientists participated in that historic first meeting. Their interests in the fungi spanned a vast geographic area of cold dominated habitats in both the northern and southern hemispheres that included four continents (N. and S. America, Eurasia,and Antarctica), nine countries, and numerous islands ranging from Greenland to Jan Mayen in the Svalbard group. ISAM-I helped to develop ongoing interests and initiate others. This is what ISAM-I founders hoped would happen. Asa result, the organizing committee for ISAM-II was formed. Its mandate was to: involve a maximum of one third new participants in future ISAM meetings: divide the responsibility for organizing future meetings at sites located in areas of interest to research thrusts in Arctic and alpine environments: keep the number of participants small enough to ensure manageability, taking full advantage of field collecting opportunities with minimal complications and cost.

Lawrie’s Meat Science has established itself as a standard work for both students and professionals in the meat industry. Its basic theme remains the central importance of biochemistry in understanding the production, storage, processing and eating quality of meat. At a time when so much controversy surrounds meat production and nutrition, Lawrie’s meat science, written by Lawrie in collaboration with Ledward, provides a clear guide which takes the reader from the growth and development of meat animals, through the conversion of muscle to meat, to the point of consumption. The seventh edition includes details of significant advances in meat science which have taken place in recent years, especially in areas of eating quality of meat and meat biochemistry. A standard reference for the meat industry Discusses the importance of biochemistry in production, storage and processing of meat Includes significant advances in meat and meat biochemistry

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.
