Trends in Species’ Gene Expression. a PCA of gene expression profiles for the three notothenioid species; blue circles represent ambient temperature controls and red circles represent individuals heated to CTMax followed by 2 h of recovery time in ambient water. Clear separation of expression profiles between controls and heat stressed individuals was found for E. maclovinus and C. rastrospinosus but not for P. borchgrevinki. One control sample was removed from P. borchgrevinki and one heat shocked sample from C. rastrospinosus both as outliers. b Histograms showing changing expression of differentially expressed genes in all three species. Y-axis is log2FC and X-axis is the number of responding genes (c) Scaled schematics comparing the magnitude (in numbers) of differentially expressed genes detected in the three species
