FIGURE 6.

The estimated number of different parental genotypes in the pedigree (${\widehat{N}}_{\mathrm{s}}$) characterized using pedigree accumulation curves for all three stream systems. For all locations, boxplot distributions for each step size overlay a line plot with a gray background for +/‐ one standard error, and labeled horizontal lines represent ${\widehat{N}}_{\mathrm{s}}$ estimates from the jackknife and chao methods. Due to the large number of individuals, the Ocqueoc River boxplots are plotted in step sizes of 5 sampled individuals and the Lower Black Mallard River boxplots are shown for sample sizes increasing by 10 individuals. The boxplots for all other locations are plotted for a step size of 1 sampled individual
