Training and intercalibration reduce observer-induced variability in forest vegetation surveys

	Figure 3. Quantile dot-plot of the expectation of the posterior predictions of beta diversity in the two exercises. The blue dots represent 100 evenly spaced quantiles of the distribution. The intervals represent 50%, 80%, 95% widths, the point represents the median.
