This topical and exciting textbook describes fisheries exploitation, biology, conservation and management, and reflects many recent and important changes in fisheries science. These include growing concerns about the environmental impacts of fisheries, the role of ecological interactions in determining population dynamics, and the incorporation of uncertainty and precautionary principles into management advice. The book draws upon examples from tropical, temperate and polar environments, and provides readers with a broad understanding of the biological, economic and social aspects of fisheries ecology and the interplay between them. As well as covering 'classical' fisheries science, the book...
The use of wildlife for food and other human needs poses one of the greatest threats to the conservation of biodiversity. Wildlife exploitation is also critically important to many people from a variety of cultures for subsistence and commerce. This book brings together international experts to examine interactions between the biology of wildlife and the divergent goals of people involved in hunting, fishing, gathering and culling wildlife. Reviews of theory show how sustainable exploitation is tied to the study of population dynamics, with direct links to reproductive rates, life histories, behaviour and ecology. As such theory is rarely put into practice to achieve sustainable use and effective conservation, Conservation of Exploited Species explores the many reasons for this failure and considers remedies to tackle them, including scientific issues such as how to incorporate uncertainty into estimations, as well as social and political problems that stem from conflicting goals in exploitation.
In the summer of 1965, an eighteen-year-old boy, filled with frustration and anger at the injustices of the segregated society in his hometown of Troy, Alabama, volunteers to help Civil Rights workers sent to Alabama by the Southern Christian Leadership Conference as part of a campaign to register black people to vote. A few short months later, he finds himself in Atlanta, standing in the sanctuary of Ebenezer Baptist Church being interviewed by Dr. Martin Luther King Jr. for a position on SCLC's field staff. As a young foot soldier in the Civil Rights Movement, author John Reynolds was an eyewitness to history. In The Fight for Freedom, he shares his experiences in some of the hot spots of ...
John Reynolds Gardiner's classic action-packed adventure story about a thrilling dogsled race has captivated readers for more than thirty years. Based on a Rocky Mountain legend, Stone Fox tells the story of Little Willy, who lives with his grandfather in Wyoming. When Grandfather falls ill, he is no longer able to work the farm, which is in danger of foreclosure. Little Willy is determined to win the National Dogsled Raceāthe prize money would save the farm and his grandfather. But he isn't the only one who desperately wants to win. Willy and his brave dog Searchlight must face off against experienced racers, including a Native American man named Stone Fox, who has never lost a race. Exciting and heartwarming, this novel has sold millions of copies and was named a New York Times Outstanding Children's Book.
The goal of this book is to provide a comprehensive and systematic introduction to the important and highly applicable method of data refinement and the simulation methods used for proving its correctness. The authors concentrate in the first part on the general principles needed to prove data refinement correct. They begin with an explanation of the fundamental notions, showing that data refinement proofs reduce to proving simulation. The book's second part contains a detailed survey of important methods in this field, which are carefully analysed, and shown to be either incomplete, with counterexamples to their application, or to be always applicable whenever data refinement holds. This is shown by proving, for the first time, that all these methods can be described and analysed in terms of two simple notions: forward and backward simulation. The book is self-contained, going from advanced undergraduate level and taking the reader to the state of the art in methods for proving simulation.
America has a long tradition of middle-class radicalism, albeit one that intellectual orthodoxy has tended to obscure. The Radical Middle Class seeks to uncover the democratic, populist, and even anticapitalist legacy of the middle class. By examining in particular the independent small business sector or petite bourgeoisie, using Progressive Era Portland, Oregon, as a case study, Robert Johnston shows that class still matters in America. But it matters only if the politics and culture of the leading player in affairs of class, the middle class, is dramatically reconceived. This book is a powerful combination of intellectual, business, labor, medical, and, above all, political history. Its a...

"Courtyards presents a survey of courtyards, contemporary design guidelines, and a diverse selection of examples. Readers will acquire a basic understanding of the balance that must exist between garden and building, including practical advice for planting."--BOOK JACKET.
An Introduction to Applied and Environmental Geophysics, 2nd Edition, describes the rapidly developing field of near-surface geophysics. The book covers a range of applications including mineral, hydrocarbon and groundwater exploration, and emphasises the use of geophysics in civil engineering and in environmental investigations. Following on from the international popularity of the first edition, this new, revised, and much expanded edition contains additional case histories, and descriptions of geophysical techniques not previously included in such textbooks. The level of mathematics and physics is deliberately kept to a minimum but is described qualitatively within the text. Relevant math...
