Variation of shell growth parameters in relation to different SST (Sea Surface Temperature). Three groups were considered: correlations in all shells, correlations in immature shells (< 18 mm), and correlations in mature shells (> 18 mm). The box colors represent the age of the assemblages, ranging from the oldest fossil horizon (dark grey boxes) to the present-day horizon (white boxes). The boxes indicate the 25th and 75th percentiles, the lines within the boxes mark the medians, and the crosses mark the mean values. Black points represent outliers. Different letters indicate statistical differences among assemblages (p < 0.05; the number of clams measured for each assemblage is reported in Table 1). rS, Spearman’s rho coefficient. ***p < 0.001, NS, not significant.
