Genetic changes in a population of F. serratus over eight generations. (Abbreviations: average number of alleles−locus (α), Hexp (non-biased), θ estimator of FST (reflecting temporal differences in allelic frequencies between 2000 and 2008) and estimates of temporal changes in Ne. Parenthetical values of Ne represent estimations without locus F65 (see table 1 legend); n.s., non-significant; *p<0.05; **p<0.001.)
