Visualization of significant model terms in generalized least squares models on body size/condition-related adult phenotypic traits. Principal components (PCs) capturing variation in environmental parameters along the examined stream gradients (Table 2) served as explanatory variables. Shown are effects for a, b body length, and c, d body weight (dry weight), which are presented separately for both sexes if the models uncovered significant sex-effects (Table 3). Solid lines show linear relationships of raw data with 95% confidence intervals (shaded area), while dashed lines represent the linear relationships based on predicted values that were adjusted for other predictors in each model. For display purpose, data points were slightly shifted using the position_jitter-function in ggplot2
