Stable Isotopes in Plant Ecology
▪ Abstract The use of stable isotope techniques in plant ecological research has grown steadily during the past two decades. This trend will continue as investigators realize that stable isotopes canExpand

Global patterns of foliar nitrogen isotopes and their relationships with climate, mycorrhizal fungi, foliar nutrient concentrations, and nitrogen availability.
Ratios of nitrogen (N) isotopes in leaves could elucidate underlying patterns of N cycling across ecological gradients. To better understand global-scale patterns of N cycling, we compiled data onExpand

  • 1 December 1998
Abstract Fog has been viewed as an important source of moisture in many coastal ecosystems, yet its importance for the plants which inhabit these ecosystems is virtually unknown. Here, I report theExpand

Hydraulic lift: consequences of water efflux from the roots of plants
Abstract Hydraulic lift is the passive movement of water from roots into soil layers with lower water potential, while other parts of the root system in moister soil layers, usually at depth, areExpand

During drought periods, sugar maple (Acer saccharum) demonstrates “hydraulic lift”; nocturnal uptake of water by roots from deep soil layers that is released from shallow roots into upper soilExpand

Water uptake by plants: perspectives from stable isotope composition
Stable isotope studies of hydrogen and oxygen stable isotope ratios of water within plants are providing new information on water sources, competitive interactions and water use patterns underExpand

Nighttime transpiration in woody plants from contrasting ecosystems.
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 plant species byExpand

The contribution of fog to the water relations of Sequoia sempervirens (D. Don): foliar uptake and prevention of dehydration
Fog is a defining feature of the coastal California redwood forest and fog inputs via canopy drip in summer can constitute 30% or more of the total water input each year. A great deal of occultExpand

Root water uptake and transport: using physiological processes in global predictions.
Plant water loss, regulated by stomata and driven by atmospheric demand, cannot exceed the maximum steady-state supply through roots. Just as an electric circuit breaks when carrying excess current,Expand

Streamside trees that do not use stream water
A LONG-STANDING axiom is that plant distribution is strongly influenced by soil moisture content1,2. While it has been shown that plant taxa inhabiting streamside communities receive or use moreExpand
