FIGURE 5.
Maximum air temperature tolerated as a function of (a) evaporative water loss inflection point and (b) average evaporative scope among 24 arid‐zone passerines and Arctic snow buntings. Evaporative scope represents the ratio between the maximum rate of EWL and the minimum rate of EWL (sensu Czenze et al., 2020). Arid species data are from McKechnie et al. (2017), Smith et al. (2017), and Czenze et al. (2020)
