Figure 3

Temperature-time duration curves from thermal dataloggers (solid lines) in our study in comparison to the minimum 50 % lethal thermal death time (TDT) curve (dotted line) from experimental data gathered by Rezende et al. (2014), graphed for the 10 plots in which a lethal heat dosage occurred. Each datalogger curve represents one quadrat in the plot, and only quadrats in which a lethal heat dosage occurred are shown. X-axes are logarithmic time (min) and y-axes are temperature (°C), with datalogger curves showing the time spent at or above each temperature. Plots are shown in order of increasing mean lethal heat dosage. Burn date and burn time are indicated in corner of each graph; additional details for each burn are in Table 3 and Table 4.
