Stable Isotope Analysis of Caribou Antlers as Ecological Indicators
This study aims to determine whether Rangifer tarandus (caribou) antlers can be used as effective ecological indicators relative to other hard tissues such as bone and teeth using stable isotopes of oxygen, carbon, and nitrogen. Variation in the rate and timing of tissue development should create di...
