<p><i>Tracking Animal Migration with Stable Isotopes, Second Edition, </i> 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.</p> <p>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.</p>

Biological control has long been used against invasive plants and, less often, invasive insects, in forests, aquatic systems, grasslands, coastal areas, riparian areas, islands, and other biomes or habitats of conservation concern. Historically, motivation for such efforts has shifted gradually away from economic interests toward ecological protection for its own sake. Future projects of this type will require better integration of biological control into conservation practice, a better understanding by societies of the reasons for such work and its possible risks and benefits, as well as continued, consistent public funding. Examples of successful projects in high-value conservation areas (Everglades, Galápagos, oceanic islands, wetlands, forests) are discussed, and future challenges and caveats mentioned. <p/> Environmentalists, nature conservationists, scientists, forestry personnel, USDA employees, and others interested in biological control would be interested in this publication. Additionally, students pursuing coursework, and research for Natural Resource Management degree programs may be interested in this work. <p/> Related products: <br><b>Plants resources collection </b>can be found here: https: //bookstore.gpo.gov/catalog/plants <p/><b>Major Forest Insect and Disease Conditions in the United States: 2013 </b>is available here: https: //bookstore.gpo.gov/products/major-forest-insect-and-disease-conditions-united-states-2013 <p/><b>Forest Health Monitoring: National Status, Trends, and Analysis 2015 </b>can be found here: https: //bookstore.gpo.gov/products/forest-health-monitoring-national-status-trends-and-analysis-2015 <p/> Other products produced by the <b>United States Department of Agriculture, U.S. Forest Service </b>are available here: https: //bookstore.gpo.gov/agency/us-forest-service <p/>
