Fig. 7. Box plots displaying the percentage of error between predicted and observed proportions of Calopteryx aequabilis along stream habitat on individual landscapes, for the Basic and P_mv parameter sets of the PERMEABILITY model. Individual boxes represent among-run variation in model fits on individual landscapes. Total variation among individual landscapes within a landscape type is represented by the blue box (Total) in each panel. The numbers along the x-axes are individual landscape designations. The plots display the median value (white bar), mean value (yellow diamond), interquartile range (box), range (whiskers), and outliers (bars). Yellow diamonds, blue boxes only, display mean percentage of error for comparison with Fig. 6. The horizontal dotted line through each panel indicates perfect agreement between predicted and observed data. Dashed lines indicate the ± 25% cutoffs for acceptable model fit. Ten replicate runs were conducted for each individual landscape.
