Fig. 1. Map of the estimatedδ 15NBase isoscape showing the
location of zooplankton sampling sites (white circles).
Fig. 2. Patterns inδ 15NBulk along the vertebral
sections of sampled Japanese chum salmon (IDs: OK1–8). Vertebral bone
sections (x -axis) are numbered from the center of the vertebral
centrum and increase toward the margin.
Fig. 3. Estimated chum salmon migration areas. Mean presence
probabilities for two salmon individuals (IDs: OK2 and OK8) at growth
stages 1–10 (panels 1–10, respectively). The color gradients (tints
of orange) indicate presence probability (low to high). The grey area
shows the extent of the isoscape.
