It is commonly assumed that transpiration does not occur at night because leaf stomata are
closed in the dark. We tested this assumption across a diversity of ecosystems and woody …

Evaluations of plant water use in ecosystems around the world reveal a shared capacity by
many different species to absorb rain, dew, or fog water directly into their leaves or plant …

Leaf water contains naturally occurring stable isotopes of oxygen and hydrogen in abundances
that vary spatially and temporally. When sufficiently understood, these can be harnessed …

Although crown wetting events can increase plant water status, leaf wetting is thought to
negatively affect plant carbon balance by depressing photosynthesis and growth. We …

The abrupt origin and rapid diversification of the flowering plants during the Cretaceous has
long been considered an “abominable mystery.” While the cause of their high diversity has …

A central challenge in plant ecology is to define the major axes of plant functional variation
with direct consequences for fitness. Central to the three main components of plant fitness (…

Mesophyll conductance significantly, and variably, limits photosynthesis but we currently
have no reliable method of measurement for C 4 plants. An online oxygen isotope technique …

Maintaining high rates of photosynthesis in leaves requires efficient movement of CO 2 from
the atmosphere to the mesophyll cells inside the leaf where CO 2 is converted into sugar. …

Many efforts to improve science teaching in higher education focus on a few faculty members
at an institution at a time, with limited published evidence on attempts to engage faculty …

Leaf hydraulic conductance (k leaf ) is a central element in the regulation of leaf water
balance but the properties of k leaf remain uncertain. Here, the evidence for the following two …
