"As I write this, I am sitting in a cabin at Cedar Point Biological Station in southwestern Nebraska.... The glorious elemental mixture of earth, water, and sky around me is the home of nearly three hundred species of birds, and comprises one of my favorite places in the world. Here no radio stations blare out the most recent results of meaningless sports events ... no traffic noises confound the senses. Instead the wind is the unquestioned dominating summer influence. The prairie grasses bend willingly and gracefully before it, and the leaves of the cottonwood trees convert its breezes into soft music."

Paul Johnsgard is one of America's most prominent ornithologists and a world authority on waterfowl behavior. In these popularly written, often lyrical essays, he describes some of his most fascinating encounters with birds, from watching the annual mating displays of prairie-chickens on a hilltop in Pawnee County, Nebraska, to attempting to solve some of the mysteries surrounding Australia's nearly flightless musk duck.

Reflecting his worldwide interests and travels, the birds Johnsgard describes inhabit many parts of the globe. Grouping the birds by the element they frequent most—earth, water, or sky—he weaves a wealth of accurate natural history into personal stories drawn from a lifetime of avian observation. And, as a bonus, Johnsgard's lovely pen-and-ink drawings illustrate each species he describes.

Marine pollution causes significant damage to fisheries and other economically productive uses of the ocean. The value of that damage can be quantified by economists, but the meanings of those valuations and how they are derived are often obscure to noneconomists.Economic Losses from Marine Pollution brings a fuller understanding of the variety and extent of marine losses and how they are assessed to scientists, lawyers, and environmentalists by systematically identifying and classifying marine losses and relating them to models and methods of economic valuation. The authors use a step-by-step approach to show how economists have used these methods and how they approach the problem of assessing economic damage.The book begins by describing the importance of economic valuation of marine damages, the history of concern over marine pollution, and the development of economic methodologies to assess damage from it. Following that, the book: considers types of marine pollution and their effects on organisms, ecosystems, and humans, and the corresponding economic effects of those biological impacts introduces the economic principles and methods needed to understand and to assess economic damages expresses losses from water quality impairments in terms of economic value introduces the basic economic techniques that have been developed and used to measure changes in economic value discusses how to apply those economic techniques, and presents a variety of practical examples explores limitations and problems that can arise in such applied work.Economic Losses from Marine Pollution includes all of the relevant economic theory together with specific examples of how that theory has been and can be applied. It offers environmental professionals with little or no background in economics the basic economic tools needed to understand economic valuations of environmental damage, and represents a unique handbook for environmental and marine scientists, lawyers, economists, policy professionals, and anyone interested in issues of marine water quality.

A unique study of an Andean community’s water rituals and the extraordinary document describing how they should be performed

In the dry season in the Andes, water from springs, lakes, reservoirs, and melting glaciers feeds irrigation canals that have sustained communities for thousands of years. Managing and maintaining these water infrastructures is essential, and in 1921, in the village of San Pedro de Casta, Peru, local authorities recorded their ritual canal-cleaning duties in a Spanish-language document called the Entablo. It is only the second book (along with the Huarochirí Manuscript) ever seen by scholars in which an Andean community explains its customs and ritual laws in its own words.

Sarah Bennison offers a critical introduction to the Entablo, a Spanish transcription of the document, and an English translation. Among its other revelations, the Entablo delves into the use of khipu boards, devices that meld the traditional knotted strings known as khipus with a written alphabet. Only in the Entablo do we learn that there were multiple khipu boards associated with a single canal-cleaning ritual, or that there were separate khipu records for men and women. The Entablo manuscript furnishes unparalleled insights into Andean rituals, religion, and community history at a historical moment when rural highland communities were changing rapidly.
