Tracking Animal Migration with Stable Isotopes


Book Description

Tracking Animal Migration with Stable Isotopes, Second Edition, provides a complete introduction to new and powerful isotopic tools and applications that track animal migration, reviewing where isotope tracers fit in the modern toolbox of tracking methods. The book provides background information on a broad range of migration scenarios in terrestrial and aquatic systems and summarizes the most cutting-edge developments in the field that are revolutionizing the way migrant individuals and populations are assigned to their true origins. It allows undergraduates, graduate students and non-specialist scientists to adopt and apply isotopes to migration research, and also serves as a useful reference for scientists. The new edition thoroughly updates the information available to the reader on current applications of this technique and provides new tools for the isotopic assignment of individuals to origins, including geostatistical multi-isotope approaches and the ways in which researchers can combine isotopes with routine data in a Bayesian framework to provide best estimates of animal origins. Four new chapters include contributions on applications to the movements of terrestrial mammals, with particular emphasis on how aspects of animal physiology can influence stable isotope values. - Includes an animal physiology component that is an in-depth overview of the cautions and caveats related to this technique - Covers marine and aquatic isoscapes and methods to track marine organisms for researchers trying to apply isotopic tracking to animals in these environments - Features state-of-the-art statistical treatments for assignment and combining diverse datasets




Variational Analysis and Applications


Book Description

This book discusses a new discipline, variational analysis, which contains the calculus of variations, differential calculus, optimization, and variational inequalities. To such classic branches of mathematics, variational analysis provides a uniform theoretical base that represents a powerful tool for the applications. The contributors are among the best experts in the field. Audience The target audience of this book includes scholars in mathematics (especially those in mathematical analysis), mathematical physics and applied mathematics, calculus of variations, optimization and operations research, industrial mathematics, structural engineering, and statistics and economics.




The Albatross and the Fish


Book Description

Breeding on remote ocean islands and spending much of its life foraging for food across vast stretches of seemingly empty seas, the albatross remains a legend for most people. And yet, humans are threatening the albatross family to such an extent that it is currently the most threatened bird group in the world. In this extensively researched, highly readable book, Robin W. Doughty and Virginia Carmichael tell the story of a potentially catastrophic extinction that has been interrupted by an unlikely alliance of governments, conservation groups, and fishermen. Doughty and Carmichael authoritatively establish that the albatross's fate is linked to the fate of two of the highest-value table fish, Bluefin Tuna and Patagonian Toothfish, which are threatened by unregulated commercial harvesting. The authors tell us that commercial fishing techniques are annually killing tens of thousands of albatrosses. And the authors explain how the breeding biology of albatrosses makes them unable to replenish their numbers at the rate they are being depleted. Doughty and Carmichael set the albatross's fate in the larger context of threats facing the ocean commons, ranging from industrial overfishing to our habit of dumping chemicals, solid waste, and plastic trash into the open seas. They also highlight the efforts of dedicated individuals, environmental groups, fishery management bodies, and governments who are working for seabird and fish conservation and demonstrate that these efforts can lead to sustainable solutions for the iconic seabirds and the entire ocean ecosystem.
