Adaptation: differential expression for each strain of redband trout across all time periods of heat stress versus fish held at control temperatures. Results for a) desert strain from Little Jacks Cr. b) F1 crosses; and c) montane strain from Keithley Cr. Genes that are significantly differentiated (FDR ≤ 0.05) are in red and those that are not significant are in black. On a log₂ scale, the green lines show genes that are ≥ 2 fold, and the blue lines designate genes that are ≥ 4 fold. The x-axis is the mean expression of each gene in counts per million reads (CPM) on a log₂ scale.
