Relationships between spatially weighted density (Eq. 3) and meter-specific mean body length of juvenile salmon in six different streams. Stream-specific values of d* used to calculate spatially weighted densities were those identified as giving the lowest AIC value (Fig. 5). Linear regression results are given; regression lines are included for significant models. For comparisons with conventional measurements of density, a homogenous density of one fish m⁻² corresponds to a spatially weighted density of 17 given the mean value of d* found in this study (11 m) and the mean width of the streams (3 m)
