Visualization of significant model terms in generalized least squares models using offspring-related phenotypic traits as the dependent variable. We depict predicted marginal effects for female fecundity along principal components that contain information of environmental variation along the examined stream gradients [(a) environmental PC 1, (b) environmental PC 2; Table 5]. 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
