Effect of lateral heat conduction between adjacent
patches
We assessed the potential influence of lateral heat conduction between
adjacent bald and hairy patches in the same leaf during cooling curves
(Supporting Information Methods S3). Our analysis suggests that the rate
of lateral heat conduction between patches was between 250 and 2,000
times smaller than the rate of convective heat loss to the air,
indicating that lateral heat conduction was unlikely to have
substantially influenced our results.
