Stable Isotopes in Plant Ecology
TLDR
How isotope measurements associated with the critical plant resources carbon, water, and nitrogen have helped deepen the understanding of plant-resource acquisition, plant interactions with other organisms, and the role of plants in ecosystem studies is reviewed.
Molecular Paleohydrology: Interpreting the Hydrogen-Isotopic Composition of Lipid Biomarkers from Photosynthesizing Organisms
TLDR
The factors and processes that are known to influence the hydrogen-isotopic compositions of lipids-especially n-alkanes-from photosynthesizing organisms are reviewed, and a framework for interpreting their D/H ratios from ancient sediments is provided to identify future research opportunities.
Global patterns of foliar nitrogen isotopes and their relationships with climate, mycorrhizal fungi, foliar nutrient concentrations, and nitrogen availability.
TLDR
It is suggested that warm, dry ecosystems have the highest N availability, while plants with high N concentrations, on average, occupy sites with higher N availability than plants with low N concentrations.
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, are
Fog in the California redwood forest: ecosystem inputs and use by plants

  • 1 December 1998
TLDR
Fog, as a meteorological factor, plays an important role in the water relations of the plants and in the hydrology of the forest, and the results presented suggest that proportional use of fog water by plants increased during the mild El Niño year of 1993.
A macroscope in the redwoods
TLDR
A case study of a wireless sensor network that recorded 44 days in the life of a 70-meter tall redwood tree, at a density of every 5 minutes in time and every 2 meters in space is presented.
Hydraulic lift and water use by plants: implications for water balance, performance and plant-plant interactions

  • 1 October 1993
TLDR
Hydraulic lift need not only occur in arid or semi-arid environments where chronic water deficits prevail, but can be important in relatively mesic environments when subjected to periodic soil water deficits, that plants neighboring trees which conduct hydraulic lift can use a significant proportion of this water source, and that the HLW source can effectively ameliorate the influence of drought on the performance and growth of neighboring vegetation.
Nighttime transpiration in woody plants from contrasting ecosystems.
TLDR
The data support four plausible explanations for the occurrence of nighttime transpiration, E(n) or g(n), which likely varies with species and ecosystem type; however, it may facilitate carbon fixation earlier in the day because stomata are already open.
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 under
Streamside trees that do not use stream water
TLDR
These analyses provide both a relatively non-destructive method for assessing water sources of plants and a means of assessing potential competitive interactions among cooccurring taxa, and may aid in resolving the role of water in determining plant distributions in areas characterized by sharp soil moisture gradients.
