Knowledge of ecological and life-history traits over ontogeny for long-lived migratory marine species is vital to creating effective conservation and management strategies, however these details are often difficult to obtain. Incrementally growing biomineralized structures, such as elasmobranch vertebrae, are metabolically stable and provide the potential to investigate changes in spatial and trophic ecology over ontogeny. In the present dissertation, chemical tracer analysis (δ13C, δ15N, and Δ14C) and opportunistic sightings data are used to address data deficiencies for a threatened marine predator (white shark, Carcharodon carcharias).
