Morphological variation vs. geographical distance along the shoreline. Variation in meristics was descibed by SR-PC1 (a), SR-PC2 (b), SR-PC3 (c) calculated on 15 meristics, variation in shape was described by PC2 (d), PC3 (e) and PC4 (f) calculated on 23 log-transformed measurements for 570 specimens from 86 locations. The distance was taken along the shoreline (in km) starting from the northwesternmost locality. LOESS curves were calculated with a fixed smoothening parameter of 0.5
