Sažetak
Sclerochronology is a developing interdisciplinary field that analyses structural elements as well as their geochemical composition of bivalves, fish, corals and algae and enables obtaining of environmental data from them. These data are of great importance for understanding of marine ecosystem-level processes and responses to climate variability. Majority of sclerochronological studies were conducted in the northern Atlantic and Pacific and there were very few studies on samples collected in semi-enclosed basins such as Adriatic and Mediterranean Seas. In recent years, several studies were conducted in the Adriatic Sea looking at shell structure and geochemical composition of several bivalve species and presentation will contain their review and current status. Target species were diverse with respect to their life history and population status – from commercially important Mediterranean scallop Pecten jacobaeus and smooth clam Callista chione, to legally protected Lithophaga lithophaga, and finally large and long lived (>50 years) bivalves Glycymeris bimaculata and Glycymeris pilosa. Methods applied include acetate peels of shell sections and analysis of stable oxygen isotopes in shell and advantages and disadvantages of each target species will be presented. Given its longevity and clarity of annual increments, G. pilosa is the best target form sclerochronological studies in the Mediterranean and has considerable potential for testing hypotheses relating to environmental variability and biological response.
