  1. Provided are the mean ± SEM differences between these two temperature measurements (Tobj − T0.98) in degrees Celsius/Kelvin for each measurement location on each species (as well as the average for all species) across both measurement protocols. ‘Repro struc’ indicating reproductive structures. For the water bath protocol mean differences are provided for both set temperatures of the water bath (35 and 45 °C), these are indicated by subscript values following mean ± SEM values
