Fig 7. Dual plots of mean δ¹³C and δ¹⁵N values for sedentary and motile invertebrates, and fish in spring (white) and fall (gray) in (A−C) intertidal and (D−F) subtidal habitats.

The groups of taxa were clustered according to the result of hierarchical cluster analysis (see details in Methods). Numbers designate different taxa (see Table 1 for species code). Circle, suspension feeder; triangle, deposit feeder; diamond, omnivore; inverted triangle, carnivore and scavenger; square, fish. Grey ellipses represent potential sources of organic matter: SPOM, suspended particulate organic matter; SOM, sedimentary organic matter; MPB, microphytobenthos.
