Fig. 4. Adaptations or plastic responses required to reverse extinction in the most sensitive life stage.

The required phenotypic changes required to maintain habitat suitability under climate warming by (A) changing r_i relative to the observed distribution of r_i in our experiments, (C) maximizing energy intake, and (E) minimizing energetic costs. Below the phenotypic responses, we demonstrate the reductions of extinction risk and increased energy balance throughout the geographic range of the species complex (B, D, and F). Green regions are predicted to have sufficient energy for growth and survival, orange regions are in negative energy balance, and grayscale regions are extinct. The maps have a spatial resolution of 1 km² over an area of 430 km × 530 km.
