Photosynthetic light-response curves describe how leaf photosynthesis
changes with light intensity, but they are time-consuming to measure,
differ between species and change depending on the growth environment of
the leaf.
Lachapelle and Shipley study
plants of 25 herbaceous species grown in four different light and
fertility environments in an interspecific context and show that
light-response curves can be predicted on the basis of two static leaf
traits that are available in large trait databases, namely specific leaf
mass and leaf nitrogen content.
