The frontier images of America embrace endless horizons, majestic herds of native ungulates, and romanticized life-styles of nomadie peoples. The images were mere reflections of vertebrates living in harmony in an ecosystem driven by the unpre dictable local and regional effects of drought, frre, and grazing. Those effects, often referred to as ecological "disturbanees," are rather the driving forces on which species depended to create the spatial and temporal heterogeneity that favored ecological prerequisites for survival. Alandscape viewed by European descendants as monotony interrupted only by extremes in weather and commonly referred to as the "Great American Desert," this country was to be rushed through and cursed, a barrier that hindered access to the deep soils of the Oregon country, the rich minerals of California and Colorado, and the religious freedom sought in Utah. Those who stayed (for lack of resources or stamina) spent a century trying to moderate the ecological dynamics of Great Plains prairies by suppressing fires, planting trees and exotic grasses, poisoning rodents, diverting waters, and homogenizing the dynamies of grazing with endless fences-all creating bound an otherwise boundless vista. aries in Historically, travelers and settlers referred to the area of tallgrasses along the western edge of the deciduous forest and extending midway across Kansas as the "True Prairie. " The grasses thlnned and became shorter to the west, an area known then as the Great Plains.

This is the first comprehensive environmental history of California’s Great Central Valley, where extensive freshwater and tidal wetlands once provided critical habitat for tens of millions of migratory waterfowl. Weaving together ecology, grassroots politics, and public policy, Philip Garone tells how California’s wetlands were nearly obliterated by vast irrigation and reclamation projects, but have been brought back from the brink of total destruction by the organized efforts of duck hunters, whistle-blowing scientists, and a broad coalition of conservationists. Garone examines the many demands that have been made on the Valley’s natural resources, especially by large-scale agriculture, and traces the unforeseen ecological consequences of our unrestrained manipulation of nature. He also investigates changing public and scientific attitudes that are now ushering in an era of unprecedented protection for wildlife and wetlands in California and the nation.

The various Red Data Books prepared by the IUCN and ICBP have set the standards for recognizing birds close to or at risk of extinction worldwide. This book, by focusing on vulnerable species living in or visiting Britain, sets out to define the British situation and to clearly establish both the importance of British populations and our own responsibilities for contributing to bird conservation. Compiled by an editorial team drawn from the Nature Conservancy Council and the Royal Society for the Protection of Birds, it identifies 117 species that demand our care and attention. It includes species that breed in or visit Britain in small numbers and whose populations are threatened by natural or man-made circumstances. It also deals with birds that are common or numerous but which, due to their localized distribution worldwide, have the greater part of their European populations in British sites. Each of the species accounts provides up-to-date information on current populations, basic ecology, threats to the species and the legal protection and conservation measures now in force. General chapters deal with the state of Britain's various habitats, legal matters and conservation action for the future. This book should mean that no-one, whether ornithologist, land manager or bureaucrat, can plead ignorance when future land-use changes or management decisions threaten an endangered, vulnerable or important bird species. Illustrated by Ian Willis.

The Poyser avifaunas Birds in Scotland, Birds in Ireland and Birds in Wales are all now regarded as classic works. The series is now completed with Birds in England, an avifauna for England's diverse birdlife, past and present. England marks the northwestern limit for many Palearctic breeding birds, and is close to the southwestern limit for several others - in particular, several seabird species whose English colonies are of international significance. It is the first point of arrival for new colonists from the south - Little Egret and Yellow-legged Gull are two recent arrivals - and it is also of international importance for wintering and passage populations of various species which breed in the far north of the Palearctic. A diverse and fascinating avifauna is augmented by visits from an impressive range of rarities from as far afield as Siberia and Canada - Nearctic vagrants in particular are well-represented on the English list. This important new avifauna looks in detail at England and its birds, analysing present and historical data to present a complete picture of the status, range and abundance of every bird on the English list.

There are four species of tundra plover: the Grey Plover, and the Eurasian, Pacific, and American golden plovers. They breed only in the northern hemisphere, principally on tundra, and migrate far south to coastal mudflats, saltings and agricultural landscapes. They have attracted avid interest from birdwatchers and researchers worldwide, not least the authors who have studied all four species. The Eurasian Golden Plover has a special claim to fame as questions over its flight speed first prompted the compilation of the world bestseller the Guinness Book of Records! This ground-breaking book on shorebirds (waders) examines the taxonomy, appearance, behaviour, ecology and conservation of Golden and Grey plovers, and compares and contrasts their natural history and biogeography. There are detailed accounts on all aspects of their lifestyle including feeding, mating, parental care, moults, migration and avoidance of predators. The personal touches in this book add immensely to its value, not least the authors' first hand experiences of the birds and their haunts. Most of their work presented here has not been published before, adding to the significance of this highly original book. Long-awaited considerations of differences in plumage, vocalisations, habitat use, breeding, movements and food are included. The links between phylogeny, biogeography and behaviour are bound to excite interest. The comparative approach is highly detailed and refreshing, and marks the book as a classic. Ingvar Byrkjedal has also contributed all of the wonderful colour and line illustrations. Over fifty-five photographs, over one hundred and twenty tables and figures, and many other embellishments complete this definitive book.

This is the third volume in the new multi-volume set, Global Biodiversity. Each volume in this series covers the biodiversity of a selection of nations in particular regions of the world. The volumes discuss and summarize the available information on both wild and cultivated plants, wild and domesticated animals, and the variety of microbes of the different nations. This volume looks at the biodiversity of selected countries of Africa, providing a rich resource of biodiversity information on countries in different parts of Africa, including: Libya, Morocco, and Egypt in North Africa countries on the east coast, including Gabon, Ghana, Sierra Leone, Togo, Senegal land-locked countries, including Burkina Faso and Zambia, countries on the west coast, including Sudan, Tanzania and South Africa With chapters written by research scientists and conservationists, the book covers geographical status, ecosystem diversity, species diversity, genetic diversity, and conservation efforts in each selected country. The authors provide statistical data on plants, animals, and microbes of that country along with genetic diversity with the focus on crop plants/cultivated plants and domesticated animals and their wild relatives. Endangered plants and animals and protected areas are discussed. Other volumes in this series include coverage of selected countries in Asia, Europe, the Americas, and Australia.

In 1984, a conference called Wildlife 2000: Modeling habitat relationships of terrestrial vertebrates, was held at Stanford Sierra Camp at Fallen Leaf Lake in the Sierra Nevada Mountains of California. The conference was well-received, and the published volume (Verner, J. , M. L. Morrison, and C. J. Ralph, editors. 1986. Wildlife 2000: modeling habitat relationships of terrestrial vertebrates, University of Wisconsin Press, Madison, Wisconsin, USA) proved to be a landmark publication that received a book award by The Wildlife Society. Wildlife 2001: populations was a followup conference with emphasis on the other major biological field of wildlife conservation and management, populations. It was held on July 29-31, 1991, at the Oakland Airport Hilton Hotel in Oakland, California, in accordance with our intent that this conference have a much stronger international representation than did Wildlife 2000. The goal of the conference was to bring together an international group of specialists to address the state of the art in wildlife population dynamics, and set the agenda for future research and management on the threshold of the 21st century. The mix of specialists included workers in theoretical, as well as practical, aspects of wildlife conservation and management. Three general sessions covered methods, modelling, and conservation of threatened species.

Sedimentary coasts with their unique forms of life and productive ecosystems are one of the most threatened parts of the biosphere. This volume analyzes and compares ecological structures and processes at sandy beaches, tidal mudflats and in shallow coastal waters all around the world. Analyses of local processes are paired with comparisons between distant shores, across latitudinal gradients or between separate biogeographic provinces. Emphasis is given to suspension feeders in coastal mud and sand, to biogenic stabilizations and disturbances in coastal sediments, to seagrass beds and faunal assemblages across latitudes and oceans, to recovery dynamics in benthic communities, shorebird predation, and to experimental approaches to the biota of sedimentary shores.

Once thought of as a pristine environment, it is now all too apparent that the Arctic is a sink for pollutants transported northwards over long distances in the atmosphere and oceans, and is also likely to be subject to major climate change as a result of global warming. Many ecologists are currently seeking to further our understanding of how arctic ecosystems function, and to detect and predict anthropogenic changes which may occur within them. This book, resulting from a British Ecological Society Special Symposium, addresses these issues.
