Figure 2. The (a) fundamental thermal performance curves (TPCs) used in the theoretical model to generate (b) the predicted realized TPCs.

Blue lines represent the TPCs of the low temperature specialist species, whereas orange lines depict the high temperature generalist species. T_optimal indicates the optimal temperature of the realized TPCs, as shown by vertical dashed lines. The horizontal dashed line represents the relative performance of the two species, which are equal to each other.
