From stable isotope ecology to forensic isotope ecology — Isotopes’ tales [PDF]

open access: yesForensic Science International, 2019
Stable isotope ecology and forensic isotope ecology are not only linked by name. More often than not, knowledge and insights gained through the former serve as a springboard for application focused work of the latter. This review aims to offer a glimpse into the fascinating world of both though with more emphasis on forensic isotope ecology.
