Baltic Sea, North Sea and Atlantic Sea regions, characterized by strong differences in (benthic) biodiversity, were compared. Mytilus spp. showed more depleted [delta]13C values than M. balthica, most evident in the Baltic Sea in spring, where also particulate organic matter and macroalgae [delta]13C values were found to be depleted. This suggested differences in food sources among the two species, consistent with the wider spectrum of food items known for M. balthica. No differences in [delta]15N values between Mytilus spp. and M. balthica, however, indicated the same trophic level within a food web. Moreover, enriched [delta]15N values, up to 2 trophic levels higher, were found at some stations for both bivalves, as an indication of local eutrophic conditions. The results suggest similar pathways in energy flow from primary producers to bivalves, irrespective of biogeographic differences related to environmental conditions and biodiversity levels." . @prefix modulo: . prodotto:ID75152 prodottidellaricerca:prodottoDi modulo:ID1916 . @prefix istituto: . prodotto:ID75152 prodottidellaricerca:prodottoDi istituto:CDS002 . @prefix unitaDiPersonaleInterno: . prodotto:ID75152 pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA10339 . istituto:CDS002 prodottidellaricerca:prodotto prodotto:ID75152 . unitaDiPersonaleInterno:MATRICOLA10339 pubblicazioni:autoreCNRDi prodotto:ID75152 . modulo:ID1916 prodottidellaricerca:prodotto prodotto:ID75152 .
