Determining the provenance of species based on biological samples is a major challenge in population ecology and food traceability. While previous research has shown the capability of bio-tracers (e.g., isotopes, trace elements) to tackle this challenge, most research employs a single bio-tracer, arguing for a species-specific approach (e.g., genomics). We developed a general framework that fully integrates multi-dimensional bio-tracer approaches and allows the creation of complex geographic fingerprints of species origin. We used both simulations and actual samples to demonstrate how the integration of heterogeneous data is a key to ascribe a sample to its true origin.
