Drought tolerance and water use by plants along an alpine topographic gradient

  title={Drought tolerance and water use by plants along an alpine topographic gradient},
  author={Steven F. Oberbauer and William Dwight Billings},
SummaryIn the alpine zones of western North American mountains, topographic-moisture gradients are the results of winter winds blowing snow from the upper windward slopes and ridgetops into snowdrifts on the lee slopes. Wet meadows at the foot of the lee slope are the result of summer snowmelt. Such gradients are repeated many times in a single mountain range. They are useful units for studies of the effects of drought and water use on patterning of alpine vegetation.The research was done… 
Phytomass and phenology of three alpine snowpatch species across a natural snowmelt gradient
The study suggests that the predicted declines in snow cover in Australia in coming decades may affect the phytomass of species that are currently constrained by late-lying snow, which may affect their long-term patterns of distribution.
Relationships between plant communities and late snow melting on Mount Prado (Northern Apennines, Italy)
Relationships between the spatial and temporal distribution of long-lasting snow-cover and the spatial distribution of plant communities above timberline were studied on Mount Prado (2054 m), a
Mortality of Australian alpine grasses (Poa spp.) after drought: species differences and ecological patterns
A simple polynomial relationship between rainfall and field soil moisture, which predicts that the alpine soils dry below wilting point several times a year, is presented, suggesting the timing of long rain-free periods may be more important than their duration.
Intraspecific variation in the water relations of Salix arctica, an arctic-alpine dwarf willow
The observed variation in patterns of stomatal conductance and in values of tissue water relations characteristics between arctic and alpine populations of S. arctica is hypothesized to have arisen in response to these different environmental regimes which represent different selective regimes that occur along the arctic-alpine environmental continuum inhabited by this wide ranging species.
This study attempts to quantify alpine snow-patch vegetation-soil communities with respect to distance from the center of the snow patch on north and south sites. Discriminant models using vegetation
Snowmelt Timing Regulates Community Composition, Phenology, and Physiological Performance of Alpine Plants
Alpine community composition and peak % cover are strongly structured by spatio-temporal patterns in snowmelt timing, and near-term, community-wide changes in phenology and physiology in response to shifts in snow melt timing or rates of soil dry down are likely to be contingent on the legacy of past climate on community structure.
Recovery of Alpine Vegetation on Small, Denuded Plots, Niwot Ridge, Colorado, U.S.A.
Small plots (0.25 to 1.0 m2) denuded 13 and 31 yr previously were studied to investigate vegetation recovery at the alpine site of the Long-Term Ecological Research network. Recovery was slow,
Alpine Nodal Ecology and Ecosystem Evolution in the North-Central Rockies (Mount Washburn; Yellowstone National Park, Wyoming)
Abstract We studied Mount Washburn (Yellowstone National Park, Wyoming) to describe alpine ecosystem function and evolution at an important site in the North-Central Rockies. To describe the alpine
Relationships between plant drought response, traits, and climate of origin for green roof plant selection.
The natural distribution of species was not related to their water use or drought response, which suggests that shrubs from less arid climates may be suitable for use on green roofs and could both improve green roof performance and biodiversity outcomes by expanding the current plant palette.
Plant Functional Groups in Alpine Fellfield Habitats of the White Mountains, California
Overall, the data on plant functional attributes showed no strong patterns of differences between categories of life forms in the fellfield community, suggesting that classicallife forms in this habitat do not represent plant functional groups.


Transpiration Rates of Alpine Plants in the Sierra Nevada of California
Field and laboratory gravimetric measurements were made of transpiration rates in several species of alpine plants from dry and moist environments in the Sierra Nevada. Maximum transpiration rates
Ecology of Subalpine Meadows in the Olympic Mountains, Washington
The following eight community types in the Olympic Mountains, delimited from an ordination of 38 plots, are described: the cushion plant type occurring in dry habitats on exposed knolls or ridge tops, the dry grass—forb type occurring on steep, dry, south— to west—facing slopes, and the moist Saussaurea forbtype occurring in shallow gullies kept moist by melting snowbanks or shallow streams.
Photosynthetic Response to Temperature and Moisture Stress of Three Timberline Meadow Species
The photosynthetic response to temperature and moisture stress of three dominants of the west, moist, and dry meadows of the central Sierra Nevada was determined and Calamagrostis photosynthesis more efficiently at lower temperatures than Carex or Potentilla.
Vertical Gradients of Water Potential and Tissue Water Relations in Sitka Spruce Trees Measured with the Pressure Chamber
Under static conditions of no water flow, a change in water potential is expected over the distance between the soil and the leaves in the canopy of a tree, and under conditions where there is a flow of water through the soil-plant-atmosphere continuum, a larger difference is to be expected as the result of the resistances to flow encountered by the moving water.
Water Relations of Selected Plant Species in the Alpine Tundra, Colorado
The changing daily pattern of leaf water potential and leaf resistance is shown to be related to the diurnal environmental pattern, to root resistances, and to the relationships between leaf resistance and leaf water possible and between leaf water Potential and leaf relative saturation deficit.
Plant transpiration at high elevations: Theory, field measurements, and comparisons with desert plants
Close agreement was observed between predicted and measured values of transpiration for the environmental and leaf parameters tested, and transpirational fluxes at higher elevations were considerably greater than expected for all leaves, especially larger leaves, due to the strong influence of increased solar heating and a greater Dwv.
Origins and Ecology of the Sierran Alpine Flora and Vegetation
The alpine flora of the Sierra Nevada has developed relatively recently and largely in situ from western American sources. The Sierra thus provides a good site for an attempt to answer the question:
Leaf and environmental parameters influencing transpiration: Theory and field measurements
For several combinations of Ta, Sffs, and rs, transpiration was minimal for a specific leaf size, and these theoretical results were compared to field measurements to evaluate the possible interactions of leaf and environmental parameters that may serve to reduce transpiration in xeric habitats.
Arctic and Alpine Vegetations: Similarities, Differences, and Susceptibility to Disturbance
According to Diels (1937), the species of plant reaching the highest elevation on Chimborazo is Draba depressa, at 5600 m. At sealevel on Kap Morris Jesup, the northernmost plant species is Saxifraga
Plants are adapted to these severe environments by employing combinations of the following general characteristics: low‐temperature metabolism, frost resistance, and the environmental cues and requirements for flowering, dormancy, regrowth, and germination.
