Although molluscs from LT and Ch presented values similar to

d13C were found in limpets from LC (5‰ depleted) and mussels
from S (2‰ depleted) (p < 0.01) (Fig. 5). Several works have reported
this pattern in organisms inhabiting beaches under the in-
fluence of freshwater discharges, either of large
