Table 3.

Clinal variation in fitness for the two cohorts planted into the Idaho garden. As we found no evidence for clines in lifetime fitness, we also analyzed fitness in the first growing season (Year 1 fitness). We included genotype as a random effect in these models. There was no evidence for curvilinear fitness clines in this dataset.
