(Top) Z. marina population differentiation, estimated by FST (using 4 loci), between meadows in Bodega Bay, Tomales Bay and San Francisco Bay did not change between two sampling times 6 to 12 years apart. Historical samples are from Kamel et al. (2012) and Ort et al. (2012). The reference line is a 1:1 line. (Bottom) Population differentiation (FST) calculated with a full set of 12 loci vs the restricted set of 4 used in the study with the fewest markers. The reference line is a 1:1 line and indicates that for these loci and populations there is little change in FST with reduced number of markers.
