Visualization of significant model terms in generalized least squares models on gill surface areas. Shown are the relationships between male gill surface areas and a environmental principal component (PC) 1 and b PC 4 (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 the model (e.g., body length). For display purpose, data points were slightly shifted using the position_jitter-function in ggplot2
