Iron (Fe) is an essential element for almost all living organisms. Since the bioavailable iron in the environment is limited, efficient dietary uptake and the development of internal storage systems are indispensable for maintaining biological functions and ecosystem processes. Tissue stable iron isotope ratio (δ⁵⁶Fe) has been proposed as a potential tracer for tracking iron sources and metabolic processes at the individual level. In this presentation, we provide an overview of δ⁵⁶Fe analyses of animal tissues (28 species in total), focusing on the diversity among animal species and the factors controlling these variations.
