Role of diet on population dynamics of the scale-worms Lepidonotus squamatus and Harmothoe imbricata(Polychaeta, Polynoidae) in the White Sea

Our results pointed out that the dietary regimes were significantly dependent on the collection site (and the respective dominant prey species) and not on the scale-worm species, suggesting that L. squamatus and H. imbricata are non-selective at the species level.
