Query: Fitting rectangles under vulnerability curves: optimal water flow
  through plants   We study an optimization problem for a model of steady state water transport
through plants that maximizes water flow subject to the constraints on
hydraulic conductance due to vulnerability to embolism (air blockage of
conduits). The model has an elementary geometric interpretation, and exhibits
bottleneck behavior where one of the plant segments limits the overall optimal
flow, sometimes in a counterintuitive way. The results show good agreement with
experimental measurements and provide support for the hypothesis that leaves
serve as a safety buffer protecting stems against excessive embolism.
