No coin nor oath required. For personal study only.
A solid introduction to stable isotopes that can also be used as an instructive review for more experienced researchers and professionals. The book approaches the use of isotopes from the perspective of ecological and biological research, but its concepts can be applied within other disciplines. A novel, step-by-step spreadsheet modeling approach is also presented for circulating tracers in any ecological system, including any favorite system an ecologist might dream up while sitting at a computer. The authorβs humorous and lighthearted style painlessly imparts the principles of isotope ecology. The attached CD-ROM contains color illustrations, spreadsheet models, technical appendices, and problems and answers.
