This study measures flower surface conductance across nine species and finds it is low and unresponsive to humidity changes, leading to linear water loss with vapor pressure deficit.

The study tests whether hydraulic costs of seed retention explain sexual dimorphism in Leucadendron, finding that branch ramification metrics do not conform to scaling relationships and sexual dimorphism does not affect hydraulic efficiency.

The paper measures leaf-level sap flow in Tabebuia rosea to study responses to light and vapor pressure deficit, finding non-linear and asymmetric patterns that differ from stem-level measurements.
