Figure 3
Variation in temperature responses, minimum torpid metabolic rate (TMRmin), and evaporative water loss (EWL) among species. (a) Minimum defended temperature and the range of temperatures which resulted in TMRmin varied among species. Grey area represents the temperature range over which the species was tested, the black bars represent the temperature range over which TMRmin was measured. The lower end of the black boxes represents the estimated minimum defended temperature, but note that asterisks highlight cases where the TMRmin temperature range reached either the upper or lower limit of the tested temperature range. (b) Within the range of temperatures at which TMRmin was measured, evaporative water loss (EWL) varied among species (high and low EWL clusters) but not TMRmin. Error bars indicate standard error and grey ovals are presented for visual interpretation. Species codes indicate the first two letters of the genus and the specific epithet (see Table 1).
