Sažetak
Sclerochronology is the study of calcified structures, including fish otoliths, bivalve shells and corals, to reconstruct the past events. During the last decades, it has become increasingly evident that bivalve shells can enhance our knowledge about climatic and environmental changes, that can, due to long life span of some bivalve species, extend for decades and centuries into past. This study was conducted in Pag bay, location for which the first bivalve chronology for the Adriatic Sea was recently developed. Samples of two bivalve species, Glycymeris bimaculata and Callista chione, were live collected by skin and SCUBA diving from 3-5 m depth in a period from May 2014 to July 2016. G. bimaculata is a large and long lived bivalve that can grow over 80 mm in length with age surpassing 60 years. The other target species (C. chione) is a commercially important bivalve whose life span can extend over four decades. We analyzed 53 samples of G. bimaculata, which ranged in length from 82 to 98 mm and 50 shells of C. chione, which ranged in length from 64 to 79 mm. Each shell length, height, width and dry shell weight was measured before every sample was cut around the hinge and embedded in epoxy resin. Embedded samples were cut along the maximum growth axis, grinded, polished and etched and acetate peel replicas of shell sections were prepared. Series of images for each specimen were taken using Zeiss microscope and camera, and composite images were prepared using Image Pro Premier program. List year method was used for visual crossdating of images. Measurements of increment widths were then continuously taken along maximal growth axis using Image Pro Premier. Crossdating was verified using program COFECHA while dendrochronology software package ARSTAN was used to construct chronologies for both G. bimaculata and C. chione. Constructed chronologies were compared to each other and to available environmental data. Advantages and challenges of use of each species for chronology construction and potential for developing multi-species chronologies in the Mediterranean Sea are presented and discussed.
