Input Prep for SIAR/MixSIAR
X-Axis: δ13C (Carbon) | Y-Axis: δ15N (Nitrogen)
Blue Dot = Corrected Consumer (Consumer - TEF)
Model Feasibility
Within Mixing Polygon
The corrected consumer value falls within the range of the source means.

Consumer & Enrichment Factors
Consumer Signature (Raw)
Trophic Enrichment (TEF)
Values to subtract from Consumer (or add to Sources) to align trophic levels.
