Hydraulic conductance and the maintenance of water balance in flowers

Flowers face desiccating conditions, yet little is known about their ability to transport water. We quantified variability in floral hydraulic conductance (Kflower) for 20 species from 10 families and related it to traits hypothesized to be …

A physiological approach to the ecology and evolution of flowers

Flowers have long been considered one of the hallmarks of angiosperm evolution. They are morphologically complex structures that both promote efficient pollination and protect the developing embryo. When it was championed in 1793 by Christian Konrad …

Uncorrelated evolution of leaf and petal venation patterns across the angiosperm phylogeny

Early angiosperm evolution, beginning approximately 140 million years ago, saw many innovations that enabled ow- ering plants to alter ecosystems globally. These included the development of novel, ower-based pollinator attrac- tion mechanisms and …

Novel patterns of hysteresis in the response of leaf-level sap flow to vapor pressure deficit

Recent methodological advances toward measuring sap flow on small- diameter stems allow for near continuous monitoring of leaf-level water flux in response to naturally varying environmental conditions. Elucidating the response functions of sap flow …

Determining the water dynamics of flowering using miniature sap flow sensors

Angiosperms dominate almost every ecosystem globally, and for the vast majority, flowering is vital to successful reproduction, yet little work has characterized the dynamics of water use during flowering and its impacts on the reproductive biology …
