Changes in Ginkgo transpiration since 1754: (A) reduction in maximum stomatal transpiration
(l·s–1·m–2) of Ginkgo (1σ error) calculated using Equation 4; (B) mean annual level of
Mississippi River at Hannibal, Missouri, (m) as a function of maximum stomatal transpiration (l·s–1·m–2)
of Ginkgo. Comparable data in panel (A) from Quercus laurifolia in Florida is from
Lammertsma et al. (2011).
