A natural abundance hydrogen stable isotope technique was used to study seasonal changes in source water utilization and water movement in the xylem of dimorphic root systems and stem bases of several woody shrubs or trees in mediterranean-type ecosystems of south Western Australia. Samples collected from the native treeBanksia prionotes over 18 months indicated that shallow lateral roots and deeply penetrating tap (sinker) roots obtained water of different origins over the course of a winter… Expand
Root distribution of Nitraria sibirica with seasonally varying water sources in a desert habitat
TLDR
The results suggested that the shrub’s root distribution and morphology were the most important determinants of its ability to utilize different water sources, and that its adjustment to water availability was significant for acclimation to the desert habitat. Expand
Coordination of rooting depth and leaf hydraulic traits defines drought-related strategies in the campos rupestres, a tropical montane biodiversity hotspot
TLDR
It is demonstrated that shallow-rooted species, more exposed to variation in water availability, have mechanisms to confer drought resistance through turgor maintenance, which support the theory of hydrological niche segregation and its underlying trade-offs related to drought resistance. Expand
Water uptake and transport in lianas and co-occurring trees of a seasonally dry tropical forest
Water uptake and transport were studied in eight liana species in a seasonally dry tropical forest on Barro Colorado Island, Panama. Stable hydrogen isotope composition (δD) of xylem and soil water,Expand
Seasonal variation of water uptake of a Quercus suber tree in Central Portugal
Hydraulic redistribution (HR) is the phenomenon where plant roots transfer water between soil horizons of different water potential. When dry soil is a stronger sink for water loss from the plantExpand
Water use patterns of co-occurring C3 and C4 shrubs in the Gurbantonggut desert in northwestern China.
TLDR
Shrubs in the Gurbantonggut desert displayed varying adaptations across species and communities through divergent root functioning and shoot eco-physiological traits, demonstrating divergent adaptations to water availability and water stress. Expand
Intraspecific variation in the use of water sources by the circum-Mediterranean conifer Pinus halepensis.
TLDR
It is found that most populations reverted to deep soil layers as the main plant water source during seasonal summer droughts, and the observed ecotypic patterns point to the adaptive relevance of resource investment in deep roots as a strategy towards securing a source of water in dry environments for P. halepensis.

Running head: Effects of drought on plant-water sources

Variation in soil water uptake and its effect on plant water status in Juglans regia L. during dry and wet seasons.
TLDR
J. regia was compelled to take a larger amount of water from the deep soil layers in the dry season, but this shift could not prevent water stress in the plant, so the xylem water δD values could be used as an indicator to investigate the water stress of plants, besides probing profiles of soil water use.

Partitioning of water resources among plants of a lowland tropical forest
TLDR
In evergreen shade-tolerant and high-light requiring shrubs and small trees, δD of xylem water was negatively correlated with transpiration rate and leaf water potential indicating that species using deeper, more abundant water resources had both higher rates of water use and more favorable leaf water status. Expand
Water relations, shoot and root architecture, and phenology of three co-occurring Banksia species: no evidence for niche differentiation in the pattern of water use
TLDR
It is concluded that co-occurrence of these species cannot be attributed to their differential partitioning of this apparently limiting resource. Expand
Mineral nutrition and transport in xylem and phloem of Banksia prionotes (Proteaceae), a tree with dimorphic root morphology
TLDR
Xylem sap of proteoid roots, lateral roots, sinker root and age classes of trunk segments, and phloem sap of mid-trunks were collected from trees of Banksia prionotes in native habitat on highly impoverished sands in south-western Australia to suggest lateral abstraction and storage of incoming phosphate in basal stem parts during winter and a subsequent release to the xylem in summer. Expand
Hydraulic lift and water use by plants: implications for water balance, performance and plant-plant interactions
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. Expand
Mineral uptake and transport in xylem and phloem of the proteaceous tree, Banksia prionotes
TLDR
Xylem sap of sinker (tap) root, cluster feeding roots, lateral roots and from an age series of main stem extensions of 6-year trees of Banksia prionotes was collected and analyzed for principal organic and inorganic solutes and indicated poor discrimination against sodium during phloem loading. Expand
Hydraulic lift: water efflux from upper roots improves effectiveness of water uptake by deep roots
TLDR
The hypothesis that water absorbed by deep roots in moist soil moves through the roots, is released in the upper soil profile at night, and is stored there until it is resorbed by roots the following day is supported. Expand
