Towards the flower economics spectrum

Understanding how floral traits affect reproduction is key for understanding genetic diversity, speciation, and trait evolution in the face of global changes and pollinator decline. However, there has not yet been a unified framework to characterize …

Recent paper proposing a Flower Economics Spectrum (FES)

New paper proposes the primary dimensons of flower construction

Flower Physiology

Defining the physiological dimensions of floral form and evolution

Energy balance implications of floral traits involved in pollinator attraction and water balance

For most angiosperms, flowers are critical to reproduction because they increase rates of outcrossing. Flowers are highly variable in numerous traits, including size, shape, and color. Most of this variation is thought to have arisen because of …

Pollination traits have physiological consequences

Accepted paper explains how flower size and color have important effects on flower energy balance.

Flower physiology is more diverse than leaf physiology

Published paper shows that flower physiological traits covary the same as leaves even though flowers are more hydraulically variable.

Hydraulic traits are more diverse in flowers than in leaves

-Maintaining water balance has been a critical constraint shaping the evolution of leaf form and function. However, flowers, which are heterotrophic and relatively short-lived, may not be constrained by the same physiological and developmental …

Water relations of Calycanthus flowers: Hydraulic conductance, capacitance, and embolism resistance

For most angiosperms, producing and maintaining flowers is critical to sexual repro- duction, yet little is known about the physiological processes involved in maintaining flowers throughout anthesis. Among extant species, flowers of the genus …

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 …
