Mean δ¹³C and δ¹⁵N ratios of prey and predator species from Nabeta (a), Shirahama (b), and Suzaki (c) ( per each species). Triangle = S. virgatus in Nabeta (a) and Shirahama (b) and A. senhousia in Suzaki (c); × = Capitulum mitella; circle = Tetraclita japonica; and square = Reishia clavigera. Error bars indicate 1 standard deviation.
