(A) Beta function (unitless) of stomatal sensitivity to leaf water potential across cases 3–8 described in Table 1. Note that y-axis values are arbitrary and were chosen to maximize visibility of the functional forms. (B) MXTE in response to changing leaf water potential across cases 3–8 in Table 1. Note that dashed lines indicate highly concave-up cost functions compared with the base scenario in a given case.
