Journal ArticleDOI
Carbon and nitrogen stable isotope fractionation in the sediment of Lake Bled (Slovenia)
TL;DR: In this article, stable isotope composition of carbon and nitrogen in the sediment and pore water of a eutrophic freshwater lake was studied based on changes in the δ13C and δ15N values of dissolved components and sediment fraction.
Journal ArticleDOI
Nutrient fluxes and sulfur cycling in the organic-rich sediment of Makirina Bay (Central Dalmatia, Croatia).
Sonja Lojen,Nives Ogrinc,Tadej Dolenec,Barbara Vokal,Janina Szaran,Goran Mihelčić,Marko Branica +6 more
TL;DR: The mirror-imaged concentration vs. depth profiles of sulfide and organic sulfur, as well as their stable isotopic compositions, show that they were formed simultaneously, most probably in competitive processes.
Journal ArticleDOI
Seasonal differences of stable isotope composition and lipid content in four bivalve species from the Adriatic Sea
Daria Ezgeta-Balić,Sonja Lojen,Tadej Dolenec,Petra Žvab Rožič,Matej Dolenec,Mirjana Najdek,Melita Peharda +6 more
TL;DR: The feeding ecology of four bivalve species co-occurring in the Mali Ston Bay was investigated by analysing the stable isotope composition and lipid content in two tissue types, indicating isotopic niche overlap in the investigated species.
Journal ArticleDOI
Ir anomalies and other elemental markers near the Palaeocene–Eocene boundary in a flysch sequence from the Western Tethys (Slovenia)
TL;DR: In this article, a flysch sequence from the Western Tethys (Goriska Brda section, W. Slovenia) was used to record one of the most important calcareous deep benthic extinctions in the history of the Earth.
Journal ArticleDOI
Qualitative interpretation of physico-chemical and isotopic parameters in the Krka River (Croatia) assessed by multivariate statistical analysis
Neven Cukrov,Nataša Tepić,Dario Omanović,Sonja Lojen,Elvira Bura-Nakić,Vjeročka Vojvodić,Ivanka Pižeta +6 more
TL;DR: In this paper, multivariate statistical analyses were applied on the measured physico-chemical (Cd, Pb, Cu, Zn, Mg, Ca, O2, alkalinity, temperature, pH, SAS, DOC and DIC) and isotopic parameters (δ13C and δ18O) to estimate and distinguish anthropogenic from natural influences to the water system of the Krka River.
