Lipids in Aquatic Ecosystems integrates this divergent literature into a coordinated, digestible form. Chapters are organized so as to discuss and synthesize the flow of lipids from lower to higher trophic levels, up to and including humans. Linkages between the production, distribution and pathways of these essential compounds within the various levels of the aquatic food webs, and their ultimate uptake by humans and other terrestrial organisms, are highlighted throughout the book. This book will be of interest to researchers and resource managers working with aquatic ecosystems.

In an age where chemicals and antibiotics are under greater scrutiny than ever, a strong understanding of the role of nutrients and feed additives is essential in the aquaculture industry. Dietary Nutrients, Additives and Fish Health is a comprehensive review of dietary nutrients, antinutritional factors and toxins, and non-nutrient dietary additives, and their effects on fish performance and immune system function, as well as overall health. The book opens with an overview of fish immune systems and health. Subsequent chapters delve into proteins and amino acids, lipids and fatty acids, carbohydrates, beta glucans, vitamins, minerals, antinutrients, mycotoxins, nucleotides, prebiotics, probiotics, organic acids and their salts, and plant extracts and their impacts on fish health, growth, and development. The text then concludes with a chapter on feeding practices. Authored by leaders in aquaculture, Dietary Nutrients, Additives and Fish Health will be an invaluable resource to graduate students, researchers and professionals alike.

Webspinner: Songs, Stories, and Reflections of Duncan Williamson, Scottish Traveller is based on more than a hundred hours of tape-recorded interviews undertaken with him in the 1980s. Williamson tells of his birth and upbringing in the west of Scotland, his family background as one of Scotland’s seminomadic travelling people, his varied work experiences after setting out from home at about age fifteen, and the challenges he later faced while raising a family of his own, living on the road for half the year. The recordings on which the book is based were made by John D. Niles, who was then an associate professor at the University of California, Berkeley. Niles has transcribed selections from his field tapes with scrupulous accuracy, arranging them alongside commentary, photos, and other scholarly aids, making this priceless self-portrait of a brilliant storyteller available to the public. The result is a delight to read. It is also a mine of information concerning a vanished way of life and the place of singing and storytelling in Traveller culture. In chapters that feature many colorful anecdotes and that mirror the spontaneity of oral delivery, readers learn much about how Williamson and other members of his persecuted minority had the resourcefulness to make a living on the outskirts of society, owning very little in the way of material goods but sustained by a rich oral heritage.
