Izotopske značilnosti lupin školjke Mytilus galloprovincialis z vzhodne Jadranske obale
Vzorce lupin Mytilus galloprovincialis smo zbrali vzdolž celotne vzhodne Jadranske obale. Analizirali smo izotopsko sestavo ogljika in kisika v kalcitnem in aragonitnem delu skeleta {;koljke M. galloprovincialis. S pomočjo stabilnih izotopov ogljika in kisika smo preverili ali so lupine školjke M. galloprovincialis dober indikator pogojev v okolju (temperature in slanosti). S pomočjo izmerjene izotopske sestave kisika v školjčnih lupinah in privzete izotopske sestave kisika v vodi smo izračunali temperature izločanja kalcitnega in aragonitnega skeleta školjke M. galloprovincialis, ki se dobro ujemajo z izmerjenimi temperaturami morske vode. Glede na rezultate izotopske sestave ogljika in kisika v lupinah lahko raziskana območja razdelimo v tri skupine: z večjim vplivom sladke vode, z manjšim vplivom sladke vode in morska okolja, kjer ni vpliva sladke vode.

Isotopic characteristics of the shells Mytilus galloprovincialis from eastern coastal area of Adriatic Sea
Samples of Mytilus galloprovincialis were collected from entire Eastern Adriatic coast to determine δ18O and δ13C performed on calcite and aragonite shell layers. The aim of this work was to check whether shells of M. galloprovincialis are good environmental indicators (water temperature, salinity). Based on measured isotopic composition of oxygen in shell layers and assumed isotopic composition in water temperatures of calcite and aragonite of shell lavers were calculated. The calculated temperatures for M. galloprovincialis shell growth of calcite and aragonite shell layer are in good agreement with measured temperatures of sea water. According to our results of δ18O and δ13C in shell layers we can separate the locations of the investigated area into three groups: those with more influence of fresh water, those with less influence of fresh water and those of marine environments.
