C and N stable isotope variability in soft tissue of invasive species Ficopomatus enigmaticus (Annelida, Polychaeta)

Ficopomatus enigmaticus (Fauvel, 1923) is a sedentary polychaete. As invasive species F. enigmaticus has been found worldwide, inhabiting coastal brackish waters, lagoons and estuaries of both hemispheres. This tubeworm (Serpulidae) builds calcareous tubes on any hard substrate with distinctive collar-like rings at irregular intervals and is relatively easy to identify. It is an efficient suspension-feeder, very tolerant and physiologically well adapted to temperature and salinity variations, eutrophic conditions and low dissolved oxygen content. Recently it’s introduced at Eastern Adriatic coast. Here we report on the first record C and N stable isotope variability in soft tissue of F. enigmaticus from Krka River Estuary and Nertva River Delta. We found that obtained results are very interest specially those of N isotope.
