Edge Effects and the Population Structure of Humboldt Bay, California, Eelgrass (Zostera marina L.)

Table 3

Values of observed and expected heterozygosity at four microsatellite loci. Data is arranged by plot and bed position. Multiply sampled multilocus genotypes were excluded. Significant values are denoted by “” which indicates a departure from Hardy-Weinberg equilibrium. To assure experimentwise error rate of 0.05, Bonferroni-corrected comparisonwise alpha values of (a) 0.00114 and (b) 0.00625 were used.
