Stable isotopes in archaeobotanical research

In recent decades the analysis of stable isotopes in plants has become a useful method to infer natural and anthropogenic effects on the growing conditions of plants. Here we present a review of the state-of-the-art regarding the use of stable isotopes in plant macroremains. After providing a brief theoretical and methodological background, we will concentrate on the most common applications developed so far: reconstruction of climate and crop growing conditions, and crop provenancing. Finally, we will discuss current methodological challenges, and potential new directions for research.
