Figure 2.

Variation in mean thermal preference among a global sample of C. elegans natural isolates. Mean thermal preferences are based on an average of 4 replicates and 233 individuals per replicate, 7484 total individuals. Values are least square means ± SEM. Isolates not connected by the same horizontal line are significantly different from one another (Tukey's HSD, p ≤ 0.05).
