Figure 6.

Elastic net estimated effects of environmental variables on generation-by-environment interactions. Network plots are used to represent the magnitude of the estimated effect of each environment variable (node) on flowering time within each generation, the correlation between environment variables (blue line=positive correlation; green line=negative correlation; line thickness represents the relative magnitude of the correlation, with no lines shown for correlations between −0.5 and 0.5), and the percent variation explained by the model (upper right corner of each network). See Materials and methods for a description of the node abbreviations. To allow for comparison among generations and between traits, the dependent variable data were rescaled using a Z-transformation (see Materials and methods).
