New in HOORC's Library: Tracking animal migration

Successful application of tagging techniques in the study of terrestrial animal migration has been somewhat limited to larger species that could be intercepted with high probability. Tracking animal migration with stable isotopes explores recent developments that have the potential to improve researchers' ability to gather new insights into wild animal mobility. The book explains that light stable isotopes -- isotopes of elements that are not radioactive -- can function as dietary tracers that indicate where an animal has been and what it has been eating. Light isotopes form the key atomic building blocks of the biosphere and most animal tissues. Samples of of animal hair, claw, muscle and blood are taken and isotope values identified -- indicating the food web in which they participate. You can find the book in HOORC's Library.
