The incorporation of environmentally derived ⁸⁷Sr/⁸⁶Sr and Sr/Ca in early otolith formation of Chinook salmon

Abstract

Effective species management and conservation often require understanding patterns of movement and habitat use. A common approach used in identifying where individuals reside relies upon chemical tracers from the environment that are incorporated into an individual's tissues. These chemical tracers, such as stable isotopes and trace elements, are used as a location-specific marker and depending on the tissue being examined can represent a variety of temporal scales from days (blood, Kurle & Gudmundson, 2007) and
