The Thermal Death Time (TDT) model has enabled quantification of heat injury in ectothermic organisms across variable thermal stress intensities and durations. Using experimental data from Drosophila suzukii , here we extend this framework to include a quantitative assessment of repair of thermal injury. We first demonstrate that heat injury accumulates additively and exponentially at stressful temperatures and subsequently sh...

Studies of ectotherm responses to heat extremes often rely on assessing absolute critical limits for heat coma or death (CT max ), however, such single parameter metrics ignore the importance of stress exposure duration. Furthermore, population persistence may be affected at temperatures considerably below CT max through decreased reproductive output. Here we investigate the relationship between tolerance duration and severity...
